本申请涉及医疗器械领域，特别是涉及一种心室连接装置及心室连接系统。The present application relates to the field of medical devices, and in particular to a ventricular connection device and a ventricular connection system.
背景技术Background technique
血泵或称心室辅助装置，用于为进展期难治性心衰患者血液循环提供机械支持，即心脏移植前或恢复心脏功能的过渡治疗以及长期治疗。血泵以并联旁路方式与患者的心室及主动脉相连，血泵的入口管从心脏心尖插入心室，由动力驱动血泵的叶轮工作，使血液由心室经泵入口进入到泵腔，在叶轮离心的作用下，将血液从泵出口排出，再经桥接的人造血管到升主动脉，从而支持患者血液循环。Blood pumps, or ventricular assist devices, are used to provide mechanical support for blood circulation in patients with progressive refractory heart failure, i.e. transitional treatment before heart transplantation or to restore heart function, as well as long-term treatment. The blood pump is connected to the patient's ventricle and aorta in a parallel bypass mode. The inlet tube of the blood pump is inserted into the ventricle from the apex of the heart. The power drives the impeller of the blood pump to work, so that blood enters the pump chamber from the ventricle through the pump inlet. Under the centrifugal action of the impeller, the blood is discharged from the pump outlet and then reaches the ascending aorta through the bridged artificial blood vessel, thereby supporting the patient's blood circulation.
在血泵植入手术中，通常需要使用心室连接装置将心室辅助装置固定安装在生物组织上。但是，相关技术中，心室连接装置和心室辅助装置固定在一起都需要多余的操作步骤。这些动作都会降低连接的效率，延长手术时间，从而使得手术风险增大。In blood pump implantation surgery, a ventricular connection device is usually required to fix the ventricular assist device on biological tissue. However, in the related art, fixing the ventricular connection device and the ventricular assist device together requires redundant operation steps. These actions will reduce the efficiency of the connection, prolong the operation time, and thus increase the risk of the operation.

本申请的心室连接装置，在手术前将连接件与心室辅助装置实现固定连接。然后，再将连接件和心室辅助装置形成的整体结构插入至底座结构中。底座结构中的锁定组件还可以在第一锁定状态和第一解锁状态之间进行切换。当锁定组件处于第一锁定状态下，心室辅助装置与心室连接装置实现了固定连接，二者之间不会发生转动或轴向运动，进而实现了心室辅助装置与天然心脏的连接。当锁定组件处于第一解锁状态下，连接件既可带动心室辅助装置相对于底座结构发生转动，也可以带动心室辅助装置脱离或插入底座结构。这样，即实现了心室辅助装置和心室连接装置之间的相对转动和轴向插拔。由此，第一方面，可以实现心室辅助装置的快速连接或分离，而不需要使用工具对心室辅助装置和心室连接装置进行紧固或松开，进而可以大大缩短手术时间，降低手术风险。第二方面，还可以实现心室辅助装置和心室连接装置之间的相对转动，从而可以随时调整心室辅助装置的出口的角度。这样，可以进一步提高手术的便利性，进而有利于进一步节约手术时间，降低手术风险。The ventricular connection device of the present application is fixedly connected to the ventricular assist device before surgery. Then, the integral structure formed by the connecting member and the ventricular assist device is inserted into the base structure. The locking assembly in the base structure can also be switched between a first locking state and a first unlocking state. When the locking assembly is in the first locking state, the ventricular assist device and the ventricular connection device are fixedly connected, and no rotation or axial movement occurs between the two, thereby realizing the connection between the ventricular assist device and the natural heart. When the locking assembly is in the first unlocking state, the connecting member can drive the ventricular assist device to rotate relative to the base structure, and can also drive the ventricular assist device to be separated from or inserted into the base structure. In this way, the relative rotation and axial plugging and unplugging between the ventricular assist device and the ventricular connection device are realized. Therefore, on the first hand, the rapid connection or separation of the ventricular assist device can be realized without the need to use tools to tighten or loosen the ventricular assist device and the ventricular connection device, thereby greatly shortening the operation time and reducing the risk of surgery. On the second hand, the relative rotation between the ventricular assist device and the ventricular connection device can also be realized, so that the angle of the outlet of the ventricular assist device can be adjusted at any time. In this way, the convenience of the operation can be further improved, which in turn will help to further save operation time and reduce operation risks.

为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似改进，因此本申请不受下面公开的具体实施例的限制。In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
正如背景技术所述，相关技术中，心室连接装置和心室辅助装置固定在一起都需要多余的操作步骤。例如，需要用工具（螺丝刀）锁紧螺钉或卡箍，从而将心室连接装置与心室辅助装置进行紧固。这些动作都会降低二者连接的效率，延长手术时间，从而使得手术风险增大。As described in the background art, in the related art, fixing the ventricular connection device and the ventricular assist device together requires redundant operation steps. For example, a tool (screwdriver) is required to tighten a screw or a clamp to fasten the ventricular connection device to the ventricular assist device. These actions will reduce the efficiency of the connection between the two, prolong the operation time, and thus increase the risk of the operation.
基于此，本申请提供一种心室连接装置及心室连接系统，以利于提高心室辅助装置的连接效率，从而降低手术时间，进而降低手术风险。Based on this, the present application provides a ventricular connection device and a ventricular connection system to improve the connection efficiency of the ventricular assist device, thereby reducing the operation time and further reducing the surgical risk.
本申请第一方面的实施例提出一种心室连接装置10，用于连接心室辅助装置200和心脏300。如图1至图3所示，心室辅助装置200包括上壳体210以及与上壳体210顶部连通的入口管220。心室连接装置10包括连接件100以及底座结构110。连接件100配置为套设于入口管220上并与上壳体210连接。如图1和图4所示，底座结构110用于与心脏300连接，底座结构110包括套设于连接件100外部的锁定组件111，锁定组件111具有第一锁定状态和第一解锁状态，在第一锁定状态下，锁定组件111与连接件100固定连接，在第一解锁状态下，连接件100可相对于锁定组件111转动以及相对于锁定组件111运动。The embodiment of the first aspect of the present application provides a ventricular connection device 10 for connecting a ventricular assist device 200 and a heart 300. As shown in FIGS. 1 to 3 , the ventricular assist device 200 includes an upper shell 210 and an inlet tube 220 connected to the top of the upper shell 210. The ventricular connection device 10 includes a connector 100 and a base structure 110. The connector 100 is configured to be sleeved on the inlet tube 220 and connected to the upper shell 210. As shown in FIGS. 1 and 4 , the base structure 110 is used to connect to the heart 300, and the base structure 110 includes a locking assembly 111 sleeved on the outside of the connector 100, and the locking assembly 111 has a first locking state and a first unlocking state. In the first locking state, the locking assembly 111 is fixedly connected to the connector 100, and in the first unlocking state, the connector 100 can rotate relative to the locking assembly 111 and move relative to the locking assembly 111.
本申请的心室连接装置10，用于连接心室辅助装置200和心脏300。心室辅助装置200例如可以为血泵。在手术前，可以提前将心室连接装置10的连接件100和心室辅助装置200的上壳体210实现连接。具体地，如图3和图4所示，上壳体210上设置有与连接件100连接的凹槽230，将心室连接装置10的连接件100套设于心室辅助装置200的入口管220上，并将连接件100卡接在凹槽230内。可选地，可采用激光焊接的方式将连接件100焊接在凹槽230内，以使连接件100与心室辅助装置200固定连接。当然，也可以采用其他方式实现连接件100和上壳体210的固定连接。由于该项工作为术前的准备工作，因此并不会增加后续的手术时间。The ventricular connection device 10 of the present application is used to connect a ventricular assist device 200 and a heart 300. The ventricular assist device 200 may be, for example, a blood pump. Before surgery, the connector 100 of the ventricular connection device 10 and the upper shell 210 of the ventricular assist device 200 may be connected in advance. Specifically, as shown in FIGS. 3 and 4 , a groove 230 connected to the connector 100 is provided on the upper shell 210, and the connector 100 of the ventricular connection device 10 is sleeved on the inlet tube 220 of the ventricular assist device 200, and the connector 100 is clamped in the groove 230. Optionally, the connector 100 may be welded in the groove 230 by laser welding so that the connector 100 is fixedly connected to the ventricular assist device 200. Of course, other methods may also be used to achieve fixed connection between the connector 100 and the upper shell 210. Since this work is preparatory work before surgery, it does not increase the subsequent surgery time.
如图2所示，当心室辅助装置200的上壳体210和入口管220、心室连接装置10的连接件100按照上述过程连接为一体后，可以形成如图2的虚线框内所示的整体结构200a。As shown in FIG2 , when the upper shell 210 and the inlet tube 220 of the ventricular assist device 200 and the connector 100 of the ventricular connection device 10 are connected together according to the above process, an overall structure 200a as shown in the dotted frame of FIG2 can be formed.
整体结构200a准备完毕后，心室辅助装置200的植入过程为：如图1所示，将人工血管400的一端与天然心脏300的主动脉410相连，另一端与整体结构200a中的心室辅助装置200的出口230相连。然后，在心脏300的心尖310处将底座结构110缝合到心尖310上。之后，如图2所示，沿着底座结构110的内孔10a在心尖310上开一个圆孔，并将整体结构200a通过底座结构110的内孔10a及心尖310的圆孔插入到心室内。当入口管220插到底，即表明心室辅助装置200与心室连接装置10连接到了一起，这样即实现了心室辅助装置200与天然心脏300的连接。After the overall structure 200a is prepared, the implantation process of the ventricular assist device 200 is as follows: as shown in FIG1 , one end of the artificial blood vessel 400 is connected to the aorta 410 of the natural heart 300, and the other end is connected to the outlet 230 of the ventricular assist device 200 in the overall structure 200a. Then, the base structure 110 is sutured to the apex 310 at the apex 310 of the heart 300. Afterwards, as shown in FIG2 , a circular hole is opened on the apex 310 along the inner hole 10a of the base structure 110, and the overall structure 200a is inserted into the ventricle through the inner hole 10a of the base structure 110 and the circular hole of the apex 310. When the inlet tube 220 is inserted to the bottom, it means that the ventricular assist device 200 is connected to the ventricular connection device 10, so that the connection between the ventricular assist device 200 and the natural heart 300 is achieved.
由上述过程可知，本申请的心室连接装置10，其连接件100需要提前套设在心室辅助装置200的入口管220上并与上壳体210连接。其底座结构110用于与心脏300的心尖310缝合。From the above process, it can be known that the connector 100 of the ventricular connection device 10 of the present application needs to be pre-mounted on the inlet tube 220 of the ventricular assist device 200 and connected to the upper shell 210. The base structure 110 is used to suture with the apex 310 of the heart 300.
进一步地，底座结构110还用于实现与心室辅助装置200的固定和分离。具体地，底座结构110包括锁定组件111，锁定组件111具有第一锁定状态和第一解锁状态，在第一锁定状态下，锁定组件111与连接件100固定连接，在第一解锁状态下，连接件100可相对于锁定组件111转动以及相对于锁定组件111运动。Furthermore, the base structure 110 is also used to achieve fixation and separation with the ventricular assist device 200. Specifically, the base structure 110 includes a locking assembly 111, and the locking assembly 111 has a first locking state and a first unlocking state. In the first locking state, the locking assembly 111 is fixedly connected to the connecting member 100, and in the first unlocking state, the connecting member 100 can rotate relative to the locking assembly 111 and move relative to the locking assembly 111.
由此，当形成的整体结构200a插入底座结构110的内孔10a中后，底座结构110的锁定组件111可以在第一锁定状态和第一解锁状态之间切换。当锁定组件111处于第一锁定状态下，锁定组件111和连接件100固定连接。此时，整体结构200a与底座结构110之间实现固定连接。也就是说，心室辅助装置200与心室连接装置10实现了固定连接，二者之间不会发生转动或轴向运动，进而实现了心室辅助装置200与天然心脏300的连接。当锁定组件111处于第一解锁状态下，连接件100可相对于锁定组件111转动例如由第一位置转动至第二位置，或者，连接件100可相对于锁定组件111发生轴向运动，例如将整体结构200a由底座结构110的内孔10a中拔出，或将整体结构200a插入底座结构110的内孔10a中。由于整体结构200a包括连接件100和心室辅助装置200，锁定组件111为底座结构110的一部分。因此此时，连接件100既可带动心室辅助装置200相对于底座结构110发生转动，也可以带动心室辅助装置200脱离或插入底座结构110。这样，即实现了心室辅助装置200和心室连接装置10之间的相对转动和插拔。Thus, after the formed integral structure 200a is inserted into the inner hole 10a of the base structure 110, the locking assembly 111 of the base structure 110 can be switched between the first locking state and the first unlocking state. When the locking assembly 111 is in the first locking state, the locking assembly 111 and the connecting member 100 are fixedly connected. At this time, the integral structure 200a and the base structure 110 are fixedly connected. In other words, the ventricular assist device 200 and the ventricular connecting device 10 are fixedly connected, and no rotation or axial movement occurs between the two, thereby realizing the connection between the ventricular assist device 200 and the natural heart 300. When the locking assembly 111 is in the first unlocking state, the connecting member 100 can rotate relative to the locking assembly 111, for example, from the first position to the second position, or the connecting member 100 can move axially relative to the locking assembly 111, for example, the integral structure 200a is pulled out of the inner hole 10a of the base structure 110, or the integral structure 200a is inserted into the inner hole 10a of the base structure 110. Since the overall structure 200a includes the connector 100 and the ventricular assist device 200, the locking assembly 111 is a part of the base structure 110. Therefore, at this time, the connector 100 can drive the ventricular assist device 200 to rotate relative to the base structure 110, and can also drive the ventricular assist device 200 to be separated from or inserted into the base structure 110. In this way, the relative rotation and insertion and removal between the ventricular assist device 200 and the ventricular connection device 10 are realized.
综上所述，本申请的心室连接装置10，在手术前将连接件100与心室辅助装置200实现固定连接。然后，再将连接件100和心室辅助装置200形成的整体结构200a插入至底座结构110中。底座结构110中的锁定组件111还可以在第一锁定状态和第一解锁状态之间进行切换。当锁定组件111处于第一锁定状态下，心室辅助装置200与心室连接装置10实现了固定连接，二者之间不会发生转动和轴向运动，进而实现了心室辅助装置200与天然心脏300的连接。当锁定组件111处于第一解锁状态下，连接件100既可带动心室辅助装置200相对于底座结构110发生转动，也可以带动心室辅助装置200脱离或插入底座结构110。这样，即实现了心室辅助装置200和心室连接装置10之间的相对转动和轴向插拔。由此，第一方面，在植入手术过程中，医生可能需要多次插入和拔出心室辅助装置200。本申请通过底座结构110中的锁定组件111，可以实现心室辅助装置200的快速连接或分离，而不需要使用工具对心室辅助装置200和心室连接装置10进行紧固或松开，进而可以大大缩短手术时间，降低手术风险。第二方面，在植入手术过程中，通常还需要旋转心室辅助装置200来调整出口230的角度，使人工血管更顺畅。因此，本申请通过底座结构110中的锁定组件111，还可以实现心室辅助装置200和心室连接装置10之间的相对转动，从而可以随时调整心室辅助装置200的出口230的角度。这样，可以进一步提高手术的便利性，进而有利于进一步节约手术时间，降低手术风险。In summary, the ventricular connection device 10 of the present application is used to achieve a fixed connection between the connector 100 and the ventricular assist device 200 before surgery. Then, the integral structure 200a formed by the connector 100 and the ventricular assist device 200 is inserted into the base structure 110. The locking assembly 111 in the base structure 110 can also be switched between a first locking state and a first unlocking state. When the locking assembly 111 is in the first locking state, the ventricular assist device 200 and the ventricular connection device 10 are fixedly connected, and no rotation or axial movement occurs between the two, thereby achieving the connection between the ventricular assist device 200 and the natural heart 300. When the locking assembly 111 is in the first unlocking state, the connector 100 can drive the ventricular assist device 200 to rotate relative to the base structure 110, and can also drive the ventricular assist device 200 to detach from or insert into the base structure 110. In this way, the relative rotation and axial insertion and removal between the ventricular assist device 200 and the ventricular connection device 10 are achieved. Therefore, on the first hand, during the implantation operation, the doctor may need to insert and remove the ventricular assist device 200 multiple times. The present application can realize the rapid connection or separation of the ventricular assist device 200 through the locking assembly 111 in the base structure 110, without the need to use tools to tighten or loosen the ventricular assist device 200 and the ventricular connection device 10, thereby greatly shortening the operation time and reducing the surgical risk. On the second hand, during the implantation operation, it is usually necessary to rotate the ventricular assist device 200 to adjust the angle of the outlet 230 to make the artificial blood vessel smoother. Therefore, the present application can also realize the relative rotation between the ventricular assist device 200 and the ventricular connection device 10 through the locking assembly 111 in the base structure 110, so that the angle of the outlet 230 of the ventricular assist device 200 can be adjusted at any time. In this way, the convenience of the operation can be further improved, which is conducive to further saving operation time and reducing surgical risks.
需要说明的是，本申请中，轴向是指入口管220的轴线所在的方向。It should be noted that, in the present application, the axial direction refers to the direction in which the axis of the inlet pipe 220 is located.
可选地，在一些实施例中，如图2至图4所示，心室连接装置10还可以包括套筒400。当连接件100与心室辅助装置200的上壳体210固定连接后，将套筒400套设在连接件100的上表面，并将套筒400与入口管220固定密封连接。具体地，可以采用激光焊接的方式实现套筒400与入口管220的连接以及密封。这样，第一方面，连接件100位于套筒400和上壳体210之间，可以避免连接件100从上壳体210上脱落，从而有利于进一步提高连接件100和上壳体210连接的稳固性和可靠性。第二方面，套筒400与入口管200实现密封，从而可以避免血液流入连接件100和入口管220之间的间隙内，从而还有利于提高心室连接装置10的密封性能。该项工作也为术前的准备工作，因此也不会增加后续的手术时间。Optionally, in some embodiments, as shown in FIGS. 2 to 4 , the ventricular connection device 10 may further include a sleeve 400. After the connector 100 is fixedly connected to the upper shell 210 of the ventricular assist device 200, the sleeve 400 is sleeved on the upper surface of the connector 100, and the sleeve 400 is fixedly sealed and connected to the inlet tube 220. Specifically, the connection and sealing of the sleeve 400 and the inlet tube 220 can be achieved by laser welding. In this way, on the first hand, the connector 100 is located between the sleeve 400 and the upper shell 210, which can prevent the connector 100 from falling off from the upper shell 210, thereby further improving the stability and reliability of the connection between the connector 100 and the upper shell 210. On the second hand, the sleeve 400 and the inlet tube 200 are sealed, thereby preventing blood from flowing into the gap between the connector 100 and the inlet tube 220, thereby also helping to improve the sealing performance of the ventricular connection device 10. This work is also a preparatory work before surgery, so it will not increase the subsequent surgery time.
在一些实施例中，如图2和图3所示，连接件100的外表面沿周向设置有第一密封槽101，心室连接装置10还包括密封件120，密封件120设置于第一密封槽101内，以对连接件100和底座结构110之间的间隙密封。本实施例中，心室连接装置10还包括密封件120。密封件120例如可以为O型圈。通过设置密封件120，从而可以对连接件100和底座结构110之间的间隙进行密封，避免血液外流，进而有利于提高心室连接装置10的密封性能和可靠性，提高手术安全性。In some embodiments, as shown in FIG. 2 and FIG. 3 , the outer surface of the connector 100 is provided with a first sealing groove 101 along the circumferential direction, and the ventricular connection device 10 further includes a sealing member 120, which is provided in the first sealing groove 101 to seal the gap between the connector 100 and the base structure 110. In this embodiment, the ventricular connection device 10 further includes a sealing member 120. The sealing member 120 may be, for example, an O-ring. By providing the sealing member 120, the gap between the connector 100 and the base structure 110 may be sealed to prevent blood from flowing out, thereby facilitating the improvement of the sealing performance and reliability of the ventricular connection device 10 and the safety of the operation.
在一些实施例中，如图2和图3所示，连接件100的外表面沿周向间隔设置有多个第一定位槽102。如图5至图8所示，锁定组件111包括至少一个滚珠111a、套设于连接件100外部的连接环111b以及套设于连接环111b外部的外环111c，连接环111b设置有至少一个沿其径向方向贯穿的第一通孔1111，外环111c的内壁设置有与第一通孔1111相对的第一抵接件1112，第一抵接件1112具有第一接触面1112a以及位于第一接触面1112a至少一侧的第二接触面1112b，第二接触面1112b与第一接触面1112a连接且朝靠近外环111c内壁的方向延伸。外环111c与连接环111b可转动连接，以使锁定组件111在第一锁定状态和第一解锁状态之间切换。如图9所示，在第一锁定状态下，滚珠111a位于第一通孔1111且分别与第一接触面1112a和第一定位槽102抵接。如图10所示，在第一解锁状态下，滚珠111a位于第一通孔1111且与第二接触面1112b抵接。In some embodiments, as shown in FIG. 2 and FIG. 3 , the outer surface of the connector 100 is provided with a plurality of first positioning grooves 102 at intervals along the circumferential direction. As shown in FIG. 5 to FIG. 8 , the locking assembly 111 includes at least one ball 111a, a connecting ring 111b sleeved on the outside of the connector 100, and an outer ring 111c sleeved on the outside of the connecting ring 111b, the connecting ring 111b is provided with at least one first through hole 1111 penetrating along its radial direction, the inner wall of the outer ring 111c is provided with a first abutment member 1112 opposite to the first through hole 1111, the first abutment member 1112 has a first contact surface 1112a and a second contact surface 1112b located at least on one side of the first contact surface 1112a, the second contact surface 1112b is connected to the first contact surface 1112a and extends in a direction close to the inner wall of the outer ring 111c. The outer ring 111c is rotatably connected to the connecting ring 111b so that the locking assembly 111 switches between the first locking state and the first unlocking state. As shown in Fig. 9, in the first locking state, the ball 111a is located in the first through hole 1111 and respectively contacts the first contact surface 1112a and the first positioning groove 102. As shown in Fig. 10, in the first unlocking state, the ball 111a is located in the first through hole 1111 and contacts the second contact surface 1112b.
本实施例提出了锁定组件111的具体结构。锁定组件111包括至少一个滚珠111a、连接环111b以及外环111c。如图6和图7所示，连接环111b设置有至少一个第一通孔1111，第一通孔1111用于容纳滚珠111a。也即，滚珠111a和第一通孔1111为一一对应关系。如图8所示，外环111c内壁设置有与第一通孔1111相对的第一抵接件1112。也即，第一抵接件1112和第一通孔1111也为一一对应关系。This embodiment proposes a specific structure of the locking assembly 111. The locking assembly 111 includes at least one ball 111a, a connecting ring 111b and an outer ring 111c. As shown in Figures 6 and 7, the connecting ring 111b is provided with at least one first through hole 1111, and the first through hole 1111 is used to accommodate the ball 111a. That is, the ball 111a and the first through hole 1111 are in a one-to-one correspondence. As shown in Figure 8, the inner wall of the outer ring 111c is provided with a first abutment 1112 opposite to the first through hole 1111. That is, the first abutment 1112 and the first through hole 1111 are also in a one-to-one correspondence.
连接环111b套设在连接件100的外部，外环111c套设在连接环111b的外部。外环111c与连接环111b可转动连接，以使锁定组件111在第一锁定状态和第一解锁状态之间切换。参照图9和图10，以下具体说明锁定组件111实现第一解锁状态和第一锁定状态的原理。The connecting ring 111b is sleeved on the outside of the connecting member 100, and the outer ring 111c is sleeved on the outside of the connecting ring 111b. The outer ring 111c is rotatably connected to the connecting ring 111b so that the locking assembly 111 switches between the first locking state and the first unlocking state. Referring to Figures 9 and 10, the principle of the locking assembly 111 realizing the first unlocking state and the first locking state is described in detail below.
如图11所示，当外环111c和连接环111b不发生转动时，滚珠111a位于第一通孔1111内，滚珠111a的一端与第一抵接件1112的第一接触面1112a抵接。这种状态下，滚珠111a的另一端会凸出于连接环111b的内表面。此时，滚珠111a会形成干涉作用，从而无法将由连接件100和心室辅助装置200形成的整体结构200a插入到底。As shown in FIG. 11 , when the outer ring 111c and the connecting ring 111b do not rotate, the ball 111a is located in the first through hole 1111, and one end of the ball 111a abuts against the first contact surface 1112a of the first abutting member 1112. In this state, the other end of the ball 111a protrudes from the inner surface of the connecting ring 111b. At this time, the ball 111a will form an interference effect, so that the integral structure 200a formed by the connecting member 100 and the ventricular assist device 200 cannot be inserted to the bottom.
如图10所示并参照图2，由于外环111c与连接环111b可转动连接。因此，首先对外环111c施加一个顺时针或逆时针的旋转力矩T，以使外环111c相对于连接环111b转动一个角度。旋转力矩T的方向可以根据第一抵接件1112上的第二接触面1112b的数量而定。例如，若第二接触面1112b为两个且位于第一接触面1112a的两侧，则既可以施加顺时针旋转力矩T，也可以施加逆时针旋转力矩T。若第二接触面1112b仅一个，则需要根据第二接触面1112b相对于第一接触面1112a的位置决定旋转力矩T的方向。在图10中，第二接触面1112b为两个且位于第一接触面1112a的两侧，因此以施加顺时针旋转力矩T为例，但并不作为对其的具体限定。As shown in FIG. 10 and with reference to FIG. 2 , since the outer ring 111c is rotatably connected to the connecting ring 111b. Therefore, firstly, a clockwise or counterclockwise rotational torque T is applied to the outer ring 111c so that the outer ring 111c rotates an angle relative to the connecting ring 111b. The direction of the rotational torque T can be determined according to the number of second contact surfaces 1112b on the first abutment member 1112. For example, if there are two second contact surfaces 1112b and they are located on both sides of the first contact surface 1112a, both a clockwise rotational torque T and a counterclockwise rotational torque T can be applied. If there is only one second contact surface 1112b, the direction of the rotational torque T needs to be determined according to the position of the second contact surface 1112b relative to the first contact surface 1112a. In FIG. 10 , there are two second contact surfaces 1112b and they are located on both sides of the first contact surface 1112a, so the application of a clockwise rotational torque T is taken as an example, but it is not a specific limitation thereto.
此时，随着外环111c的转动，使得第一抵接件1112的第二接触面1112b与滚珠111a抵接。由于第二接触面1112b朝向外环111c内壁方向延伸，也即第二接触面1112b更靠近外环111c内壁。因此，滚珠111a在径向上的空间增加，进而使得滚珠111a可以在第一通孔1111的延伸方向上运动。在这种情况下，滚珠111a的一端与第二接触面1112b抵接，则另一端不会凸出于连接环111b的内表面。这样，锁定组件111即为第一解锁状态。此时，即可将整体结构200a插入至底座结构110中，或者，将整体结构200a从底座结构110中拔出。也即，在第一解锁状态，可以实现心室辅助装置200的快速轴向插拔和周向转动。At this time, as the outer ring 111c rotates, the second contact surface 1112b of the first abutment member 1112 abuts against the ball 111a. Since the second contact surface 1112b extends toward the inner wall of the outer ring 111c, that is, the second contact surface 1112b is closer to the inner wall of the outer ring 111c. Therefore, the radial space of the ball 111a increases, so that the ball 111a can move in the extension direction of the first through hole 1111. In this case, one end of the ball 111a abuts against the second contact surface 1112b, and the other end does not protrude from the inner surface of the connecting ring 111b. In this way, the locking assembly 111 is in the first unlocked state. At this time, the overall structure 200a can be inserted into the base structure 110, or the overall structure 200a can be pulled out from the base structure 110. That is, in the first unlocked state, the ventricular assist device 200 can be quickly inserted and pulled out in the axial direction and rotated in the circumferential direction.
若需要将整体结构200a和底座结构110二者进行锁定，则可以对外环111c施加与旋转力矩T的方向相反的旋转力矩。这样，如图9所示，随着外环111c的转动，外环111c第一抵接件1112的第一接触面1112a重新与滚珠111a抵接。在这个过程中，滚珠111a在第一通孔1111内朝靠近连接件100的方向运动，最终使得滚珠111a的一端固定在连接件100的第一定位槽102内，另一端与第一接触面1112a抵接。在这种情况下，锁定组件111即处于第一锁定状态。也即，心室辅助装置200和心室连接装置10实现了固定连接。If it is necessary to lock both the overall structure 200a and the base structure 110, a rotational torque in the opposite direction to the rotational torque T can be applied to the outer ring 111c. In this way, as shown in Figure 9, as the outer ring 111c rotates, the first contact surface 1112a of the first abutment 1112 of the outer ring 111c abuts against the ball 111a again. In this process, the ball 111a moves in the first through hole 1111 toward the direction close to the connecting member 100, and finally one end of the ball 111a is fixed in the first positioning groove 102 of the connecting member 100, and the other end abuts against the first contact surface 1112a. In this case, the locking assembly 111 is in the first locking state. That is, the ventricular assist device 200 and the ventricular connecting device 10 are fixedly connected.
若需要将整体结构200a和底座结构110二者由锁定变为解锁。此时，只需要重复前述的过程，将外环111c相对于连接环111b转动一个角度，使得外环111c的第一抵接件1112的第二接触面1112b与滚珠111a抵接即可。If the overall structure 200a and the base structure 110 need to be unlocked from being locked, the above process only needs to be repeated, and the outer ring 111c is rotated by an angle relative to the connecting ring 111b, so that the second contact surface 1112b of the first abutting member 1112 of the outer ring 111c abuts against the ball 111a.
上述过程中，滚珠111a始终有一部分位于第一通孔1111内。当整体结构200a未插入锁定组件111内时，为了避免滚珠111a从第一通孔1111的内部脱落，第一通孔1111可以为锥形通孔。具体地，第一通孔1111靠近连接件100的一侧的孔径小于第一通孔1111靠近外环111c的一侧的孔径。In the above process, a part of the ball 111a is always located in the first through hole 1111. When the overall structure 200a is not inserted into the locking assembly 111, in order to prevent the ball 111a from falling off from the inside of the first through hole 1111, the first through hole 1111 may be a tapered through hole. Specifically, the aperture of the first through hole 1111 on the side close to the connector 100 is smaller than the aperture of the first through hole 1111 on the side close to the outer ring 111c.
可选地，在一些实施例中，第二接触面1112b为两个且位于第一接触面1112a的两侧，第二接触面1112b为斜面。Optionally, in some embodiments, there are two second contact surfaces 1112b located on both sides of the first contact surface 1112a, and the second contact surface 1112b is an inclined surface.
在一些实施例中，如图9所示，连接环111b沿其周向间隔设置有三个第一通孔1111，外环111c的内壁设置有与三个第一通孔1111相对的三个第一抵接件1112，滚珠111a的数量与第一通孔1111的数量相同。In some embodiments, as shown in Figure 9, the connecting ring 111b is provided with three first through holes 1111 along its circumferential interval, the inner wall of the outer ring 111c is provided with three first abutment members 1112 opposite to the three first through holes 1111, and the number of balls 111a is the same as the number of the first through holes 1111.
本实施例中，第一通孔1111、滚珠111a以及第一抵接件1112的数量均为三个。由前述的锁定和解锁原理可知，在第一锁定状态下，是依靠滚珠111a来提供底座结构110和整体结构200a之间的锁紧力。滚珠111a的数量越多，在第一锁定状态下，底座结构110和整体结构200a之间越不容易因外力而发生脱落。通过设置多个第一通孔1111、滚珠111a以及第一抵接件1112，从而有利于提高在第一锁定状态下底座结构110和整体结构200a之间连接的可靠性和稳固性，进而有利于提高手术的安全性。In this embodiment, the number of the first through holes 1111, the balls 111a and the first abutment members 1112 are all three. It can be seen from the aforementioned locking and unlocking principles that in the first locking state, the balls 111a are relied upon to provide the locking force between the base structure 110 and the overall structure 200a. The more the balls 111a are, the less likely it is that the base structure 110 and the overall structure 200a will fall off due to external forces in the first locking state. By providing a plurality of first through holes 1111, balls 111a and first abutment members 1112, it is helpful to improve the reliability and stability of the connection between the base structure 110 and the overall structure 200a in the first locking state, thereby helping to improve the safety of the operation.
需要说明的是，第一通孔1111、滚珠111a以及第一抵接件1112的数量还可以为两个、四个等，具体可根据实际情况灵活设置。It should be noted that the number of the first through hole 1111 , the ball 111 a and the first abutment member 1112 may also be two, four, etc., and may be flexibly set according to actual conditions.
在一些实施例中，如图7、图8和图9所示，连接环111b的外壁设置有第一配合部1113，第一配合部1113的上表面设置有凹槽1113a，外环111c的内壁设置有与第一配合部1113上表面贴合的第二配合部1114，第二配合部1114设置有与凹槽1113a相对的断口1114a，凹槽1113a和断口1114a共同形成第一容纳腔S1，锁定组件111还包括设置于第一容纳腔S1内的弹性元件111d。In some embodiments, as shown in Figures 7, 8 and 9, the outer wall of the connecting ring 111b is provided with a first matching portion 1113, the upper surface of the first matching portion 1113 is provided with a groove 1113a, the inner wall of the outer ring 111c is provided with a second matching portion 1114 that is in contact with the upper surface of the first matching portion 1113, the second matching portion 1114 is provided with a break 1114a opposite to the groove 1113a, the groove 1113a and the break 1114a together form a first accommodating cavity S1, and the locking assembly 111 also includes an elastic element 111d arranged in the first accommodating cavity S1.
本实施例中，锁定组件111还包括弹性元件111d。如图7和图8所示，连接环111b的外壁设置有第一配合部1113，外环111c的内壁设置有与第一配合部1113上表面贴合的第二配合部1114。也即，当连接环111b与外环111c装配后，第一配合部1113和第二配合部1114贴合，且第二配合部1114位于第一配合部1113的上表面。进一步地，第一配合部1113的上表面设置有凹槽1113a，第二配合部1114设置有与凹槽1113a相对的断口1114a。当二者贴合后，凹槽1113a和断口1114a共同形成上方具有开口的第一容纳腔S1。本实施例将弹性元件111d设置在第一容纳腔S1内。这样，当外环111c相对于连接环111b发生转动时，由于弹性元件111d既与外环111c的断口1114a侧壁抵接，同时还与凹槽1113a的侧壁抵接。因此，弹性元件111d会因外环111c的转动而发生压缩，进而产生反作用力。In this embodiment, the locking assembly 111 further includes an elastic element 111d. As shown in FIGS. 7 and 8 , the outer wall of the connecting ring 111b is provided with a first matching portion 1113, and the inner wall of the outer ring 111c is provided with a second matching portion 1114 that fits with the upper surface of the first matching portion 1113. That is, when the connecting ring 111b is assembled with the outer ring 111c, the first matching portion 1113 and the second matching portion 1114 fit together, and the second matching portion 1114 is located on the upper surface of the first matching portion 1113. Further, the upper surface of the first matching portion 1113 is provided with a groove 1113a, and the second matching portion 1114 is provided with a break 1114a that is opposite to the groove 1113a. When the two fit together, the groove 1113a and the break 1114a together form a first accommodating cavity S1 with an opening on the top. In this embodiment, the elastic element 111d is arranged in the first accommodating cavity S1. Thus, when the outer ring 111c rotates relative to the connecting ring 111b, the elastic element 111d abuts against the side wall of the break 1114a of the outer ring 111c and the side wall of the groove 1113a. Therefore, the elastic element 111d is compressed by the rotation of the outer ring 111c, thereby generating a reaction force.
弹性元件111d的作用有多种。第一方面，当施加旋转力矩T使外环111c相对于连接环111b转动一个角度后，第一抵接件1112的第二接触面1112b与滚珠111a抵接。此时，弹性元件111d被压缩，锁定组件111处于第一解锁状态。在这种状态下，可以完成心室辅助装置200的快速插拔或角度调整等工作。当这些工作完成后，弹性元件111d可以提供反作用力，使得外环111c相对于连接环111b恢复原位。此时，滚珠111a的一端固定在连接件100的第一定位槽102内，另一端与第一接触面1112a抵接，弹性元件111d恢复原状，锁定组件111处于第一锁定状态。在这种状态下，心室辅助装置200和心室连接装置10实现了固定连接。通过设置弹性元件111d，从而可以提供反作用力，而不需要人为进行操作，进而利于提高锁定组件111在第一锁定状态和第一解锁状态切换的便利性。第二方面，弹性元件111d可以以预压缩的状态设置在第一容纳腔S1内。此时，弹性元件111d具备初始的反作用力。这样，可以提高驱动外环111c相对于连接环111b转动的作用力，避免外环111c轻易发生转动，进而有利于提高锁定组件111在第一锁定状态下的可靠性。The elastic element 111d has multiple functions. On the one hand, when the rotational torque T is applied to rotate the outer ring 111c relative to the connecting ring 111b by an angle, the second contact surface 1112b of the first abutment member 1112 abuts against the ball 111a. At this time, the elastic element 111d is compressed, and the locking assembly 111 is in the first unlocking state. In this state, the quick plug-in and pull-out or angle adjustment of the ventricular assist device 200 can be completed. When these tasks are completed, the elastic element 111d can provide a reaction force to restore the outer ring 111c to its original position relative to the connecting ring 111b. At this time, one end of the ball 111a is fixed in the first positioning groove 102 of the connecting member 100, and the other end abuts against the first contact surface 1112a, the elastic element 111d returns to its original state, and the locking assembly 111 is in the first locking state. In this state, the ventricular assist device 200 and the ventricular connection device 10 are fixedly connected. By setting the elastic element 111d, a reaction force can be provided without manual operation, which is conducive to improving the convenience of switching the locking assembly 111 between the first locked state and the first unlocked state. On the second aspect, the elastic element 111d can be set in the first accommodating cavity S1 in a pre-compressed state. At this time, the elastic element 111d has an initial reaction force. In this way, the force driving the outer ring 111c to rotate relative to the connecting ring 111b can be increased, and the outer ring 111c can be prevented from rotating easily, which is conducive to improving the reliability of the locking assembly 111 in the first locked state.
可选地，弹性元件111d可以为压缩弹簧、橡胶弹簧等中的一种。Optionally, the elastic element 111d may be a compression spring, a rubber spring, or the like.
可选地，为了提高转动外环111c的便利性，外环111c的外表面还设置有外齿1115，这样方便手术工具对外环111c的夹持。Optionally, in order to improve the convenience of rotating the outer ring 111c, the outer surface of the outer ring 111c is further provided with outer teeth 1115, so as to facilitate the clamping of the outer ring 111c by surgical tools.
需要说明的是，在图8中，第二配合部1114与第一抵接件1112为一体式结构。当然，第二配合部1114与第一抵接件1112还可以间隔设置，本申请对此不作限制。It should be noted that, in Fig. 8, the second matching portion 1114 and the first abutting member 1112 are an integrated structure. Of course, the second matching portion 1114 and the first abutting member 1112 can also be arranged at intervals, and the present application does not limit this.
此外，本申请中，上方、上表面是指，当心室连接装置10的底座结构110缝合至心尖310后，靠近心尖310的一侧为上，背离心尖310的一侧为与上相对的下。In addition, in the present application, the upper side and the upper surface mean that when the base structure 110 of the ventricular connection device 10 is sutured to the apex 310, the side close to the apex 310 is the upper side, and the side facing away from the apex 310 is the lower side opposite to the upper side.
在一些实施例中，如图4、图6和图11所示，底座结构110还包括缝合组件112，缝合组件112包括压圈112a、缝合裙边112b以及内环112c，压圈112a与连接环111b的上表面连接，内环112c与连接环111b的内表面连接，缝合裙边112b位于内环112c与压圈112a之间。In some embodiments, as shown in Figures 4, 6 and 11, the base structure 110 also includes a suturing assembly 112, which includes a pressure ring 112a, a suturing skirt 112b and an inner ring 112c, the pressure ring 112a is connected to the upper surface of the connecting ring 111b, the inner ring 112c is connected to the inner surface of the connecting ring 111b, and the suturing skirt 112b is located between the inner ring 112c and the pressure ring 112a.
本实施例中，底座结构110还包括缝合组件112，缝合组件112用于将底座结构110缝合至心尖310上。缝合组件112包括压圈112a、缝合裙边112b以及内环112c。压圈112a的一端与连接环111b的上表面连接，另一端压紧缝合裙边112b，从而有利于提高压圈112a和缝合裙边112b之间的密封性能。缝合裙边112b需要缝合到心尖310上，缝合裙边112b大致呈喇叭状，这样，有利于提高缝合的便利性。缝合裙边112b可以为涤纶布材料。内环112c与连接环111b的内表面连接。这样，可以实现连接环111b、压圈112a、缝合裙边112b以及内环112c之间的轴向固定。本实施例中，底座结构110的缝合组件112可以实现底座结构110与心尖310的连接，锁定组件111可以实现底座结构110与整体结构200a的锁定和解锁。并且，缝合组件112和锁定组件111可以紧密连接为一体。这样，使得底座结构110的整体轴向尺寸较小。如图1所示，当心室辅助装置200与心脏300连接后，二者之间的距离仅为底座结构110的轴向尺寸。这样，可以整体减小心室辅助装置200以及心室连接装置10的占用空间，尽可能降低因植入心室辅助装置200和心室连接装置10而对人体产生的不良影响，进而有利于进一步降低手术的风险。In this embodiment, the base structure 110 further includes a suturing assembly 112, which is used to suturing the base structure 110 to the apex 310. The suturing assembly 112 includes a pressure ring 112a, a suturing skirt 112b, and an inner ring 112c. One end of the pressure ring 112a is connected to the upper surface of the connecting ring 111b, and the other end presses the suturing skirt 112b, which is conducive to improving the sealing performance between the pressure ring 112a and the suturing skirt 112b. The suturing skirt 112b needs to be sutured to the apex 310, and the suturing skirt 112b is roughly trumpet-shaped, which is conducive to improving the convenience of suturing. The suturing skirt 112b can be made of polyester cloth. The inner ring 112c is connected to the inner surface of the connecting ring 111b. In this way, axial fixation between the connecting ring 111b, the pressure ring 112a, the suturing skirt 112b, and the inner ring 112c can be achieved. In this embodiment, the suturing assembly 112 of the base structure 110 can realize the connection between the base structure 110 and the apex 310, and the locking assembly 111 can realize the locking and unlocking of the base structure 110 and the overall structure 200a. In addition, the suturing assembly 112 and the locking assembly 111 can be tightly connected as a whole. In this way, the overall axial dimension of the base structure 110 is smaller. As shown in FIG. 1 , when the ventricular assist device 200 is connected to the heart 300, the distance between the two is only the axial dimension of the base structure 110. In this way, the space occupied by the ventricular assist device 200 and the ventricular connection device 10 can be reduced as a whole, and the adverse effects on the human body caused by the implantation of the ventricular assist device 200 and the ventricular connection device 10 can be reduced as much as possible, which is conducive to further reducing the risk of surgery.
在一些实施例中，如图7所示，连接环111b的外壁沿周向间隔设置有至少一个限位部1116，限位部1116位于第一通孔1111的一侧，限位部1116配置为限定外环111c相对于连接环111b的转动角度。In some embodiments, as shown in FIG. 7 , at least one limiting portion 1116 is circumferentially spaced apart on the outer wall of the connecting ring 111b. The limiting portion 1116 is located on one side of the first through hole 1111 and is configured to limit the rotation angle of the outer ring 111c relative to the connecting ring 111b.
由前述第一锁定状态和第一解锁状态的论述中可知，滚珠111a仅在第一接触面1112a和第二接触面111两个位置进行切换，从而可避免滚珠111a因空间过大而从第一通孔1111内脱离，掉入至外环111c和内环111b之间的间隙内。由此，本实施例中，连接环111b的外壁设置有限位部1116。这样，在转动外环111c的过程中，限位部1116会与第一抵接件1112发生干涉，从而可以避免外环111c相对于连接环111转动的角度过大，进而避免滚珠111a从第一通孔1111中流出而掉入至外环111c和内环111b之间的间隙内，进而有利于提高锁定组件111工作的可靠性。As can be seen from the above discussion of the first locking state and the first unlocking state, the ball 111a is switched only between the first contact surface 1112a and the second contact surface 111, thereby preventing the ball 111a from escaping from the first through hole 1111 due to the large space and falling into the gap between the outer ring 111c and the inner ring 111b. Therefore, in this embodiment, the outer wall of the connecting ring 111b is provided with a limiting portion 1116. In this way, during the rotation of the outer ring 111c, the limiting portion 1116 will interfere with the first abutment 1112, thereby preventing the outer ring 111c from rotating too much relative to the connecting ring 111, thereby preventing the ball 111a from flowing out of the first through hole 1111 and falling into the gap between the outer ring 111c and the inner ring 111b, thereby facilitating the improvement of the reliability of the locking assembly 111.
在一些实施例中，如图11和图12所示，压圈112a靠近连接环111b的一侧表面设置有至少一个第一凸起1117，第一凸起1117与限位部1116错位设置，以使压圈112a和连接环111b周向固定。本实施例中，压圈112a靠近连接环111b的一侧表面设置有至少一个第一凸起1117。并且，第一凸起1117与限位部1116在连接环111b的厚度方向错位设置。这样，当压圈112a与连接环111b的上表面连接时，第一凸起1117会插入限位部1116一侧的凹陷处，从而实现压圈112a和连接环111b的周向固定，避免二者发生转动。In some embodiments, as shown in FIG. 11 and FIG. 12 , at least one first protrusion 1117 is provided on a side surface of the pressing ring 112a close to the connecting ring 111b, and the first protrusion 1117 is staggered with the limiting portion 1116 so as to fix the pressing ring 112a and the connecting ring 111b circumferentially. In this embodiment, at least one first protrusion 1117 is provided on a side surface of the pressing ring 112a close to the connecting ring 111b. Moreover, the first protrusion 1117 and the limiting portion 1116 are staggered in the thickness direction of the connecting ring 111b. In this way, when the pressing ring 112a is connected to the upper surface of the connecting ring 111b, the first protrusion 1117 will be inserted into the recess on one side of the limiting portion 1116, thereby realizing the circumferential fixation of the pressing ring 112a and the connecting ring 111b and preventing the two from rotating.
可选地，第一凸起1117为三个，且周向均匀设置。Optionally, there are three first protrusions 1117 , and they are evenly arranged in the circumferential direction.
在一些实施例中，如图6、图7、图11和图12所示，连接环111b的内壁沿周向设置有第一连接槽1118，内环112c的外表面设置有与第一连接1118相适配的第二连接槽1119，底座结构110还包括卡环113，卡环113位于第一连接槽1118和第二连接槽1119之间，以使内环112c和连接环111b轴向固定。本实施例中，底座结构110还包括卡环113。卡环113卡接于第一连接槽1118和第二连接槽1119形成的容纳腔内，从而实现内环112c和连接环111b的轴向固定。这样，通过内环112c依次压紧缝合裙边112b、压圈112a、连接环111b以及外环111c。In some embodiments, as shown in FIG. 6, FIG. 7, FIG. 11 and FIG. 12, the inner wall of the connecting ring 111b is provided with a first connecting groove 1118 along the circumferential direction, the outer surface of the inner ring 112c is provided with a second connecting groove 1119 adapted to the first connecting groove 1118, and the base structure 110 further includes a snap ring 113, and the snap ring 113 is located between the first connecting groove 1118 and the second connecting groove 1119, so as to axially fix the inner ring 112c and the connecting ring 111b. In this embodiment, the base structure 110 further includes a snap ring 113. The snap ring 113 is clamped in the accommodating cavity formed by the first connecting groove 1118 and the second connecting groove 1119, so as to achieve axial fixation of the inner ring 112c and the connecting ring 111b. In this way, the sewing skirt 112b, the pressing ring 112a, the connecting ring 111b and the outer ring 111c are sequentially pressed by the inner ring 112c.
在一些实施例中，如图6、图7和图12所示，内环112c的外表面周向设置有至少一个第二凸起1120，连接环111b的内壁设置有与第二凸起1120相适配的第一限位槽1121，第二凸起1120与第一限位槽1121配合，以使内环112c和连接环111b周向固定。本实施例中，通过第二凸起1120和第一限位槽1121的配合，从而实现内环112c和连接环111b的周向固定，避免二者发生相对转动。可选地，第二凸起1120和第一限位槽1121还可以互换位置。也即，连接环111b的内壁周向设置第二凸起1120，内环112c的外表面设置第一限位槽1121，本申请对此不作限制。可选地，第二凸起1120和第一限位槽1121的数量均为三个。In some embodiments, as shown in FIG. 6, FIG. 7 and FIG. 12, at least one second protrusion 1120 is circumferentially arranged on the outer surface of the inner ring 112c, and a first limiting groove 1121 adapted to the second protrusion 1120 is arranged on the inner wall of the connecting ring 111b, and the second protrusion 1120 cooperates with the first limiting groove 1121 to fix the inner ring 112c and the connecting ring 111b circumferentially. In this embodiment, the circumferential fixation of the inner ring 112c and the connecting ring 111b is achieved by the cooperation of the second protrusion 1120 and the first limiting groove 1121, so as to prevent the two from rotating relative to each other. Optionally, the second protrusion 1120 and the first limiting groove 1121 can also interchange positions. That is, the inner wall of the connecting ring 111b is circumferentially arranged with the second protrusion 1120, and the outer surface of the inner ring 112c is arranged with the first limiting groove 1121, and the present application does not limit this. Optionally, the number of the second protrusions 1120 and the number of the first limiting grooves 1121 are both three.
在一些实施例中，如图2至图4所示，连接件100的外表面沿周向间隔设置有多个第二定位槽103，第二定位槽103位于第一定位槽102的上方，锁定组件111还具有第二锁定状态，外环111c与连接环111b可转动连接，以使锁定组件111在第二锁定状态和第一解锁状态之间切换，在第二锁定状态下，滚珠111a位于第一通孔1111内且分别与第一接触面1112a和第二定位槽103抵接。In some embodiments, as shown in Figures 2 to 4, a plurality of second positioning grooves 103 are circumferentially spaced apart on the outer surface of the connector 100, and the second positioning grooves 103 are located above the first positioning grooves 102. The locking assembly 111 also has a second locking state, and the outer ring 111c is rotatably connected to the connecting ring 111b so that the locking assembly 111 can switch between the second locking state and the first unlocking state. In the second locking state, the ball 111a is located in the first through hole 1111 and abuts against the first contact surface 1112a and the second positioning groove 103, respectively.
本实施例中，连接件100的外表面还设置有第二定位槽103，第二定位槽103位于第一定位槽102的上方。这样，使得本申请的锁定组件111还具有第二锁定状态。由于前文已经详细描述过第一锁定状态和第一解锁状态实现的原理，因此此处不再赘述。在手术时，首先需要将锁定组件111切换至第一解锁状态，然后才能实现心室辅助装置200与底座结构110的周向转动，以及将心室辅助装置200轴向插入到底。但是，锁定组件111切换状态时，需要使外环111c相对于连接环111b转动一个角度。而在底座结构110未与整体结构200a连接时，若转动外环111c，则连接环111b会跟随外环111c一起转动，从而无法实现锁定组件111的状态切换。In this embodiment, the outer surface of the connector 100 is further provided with a second positioning groove 103, and the second positioning groove 103 is located above the first positioning groove 102. In this way, the locking assembly 111 of the present application also has a second locking state. Since the principles of the first locking state and the first unlocking state have been described in detail above, they will not be repeated here. During surgery, the locking assembly 111 needs to be switched to the first unlocking state first, and then the ventricular assist device 200 and the base structure 110 can be rotated circumferentially, and the ventricular assist device 200 can be inserted axially to the bottom. However, when the locking assembly 111 switches the state, the outer ring 111c needs to be rotated by an angle relative to the connecting ring 111b. When the base structure 110 is not connected to the overall structure 200a, if the outer ring 111c is rotated, the connecting ring 111b will rotate with the outer ring 111c, so that the state switching of the locking assembly 111 cannot be achieved.
由此，本实施例中，在连接件100的外表面设置有第二定位槽103。这样，如图13所示，在手术时，可以先将整体结构200a插入至底座结构110的内孔10a内，使得滚珠111a的一端位于第二定位槽103内，另一端与第一接触面1112a抵接。也即，在插入的轴向力作用下，滚珠111a可以直接卡接入第二定位槽103内，从而使锁定组件111处于第二锁定状态。这样，在转动外环111c时，连接环111b不会跟随外环111c一起转动，从而可以实现锁定组件111在第一锁定状态和第一解锁状态的切换，最终如图4所示，将整体结构200a插到底。换句话说，第二定位槽103可以实现锁定组件111中的连接环111b和连接件100之间的预固定，之后即可对外环111c施加驱动力矩，实现锁定组件111在第一锁定状态和第一解锁状态的切换。由此，有利于提高锁定组件111状态切换的便利性。Therefore, in this embodiment, a second positioning groove 103 is provided on the outer surface of the connecting member 100. Thus, as shown in FIG13 , during surgery, the overall structure 200a can be first inserted into the inner hole 10a of the base structure 110, so that one end of the ball 111a is located in the second positioning groove 103, and the other end is in contact with the first contact surface 1112a. That is, under the action of the axial force of insertion, the ball 111a can be directly inserted into the second positioning groove 103, so that the locking assembly 111 is in the second locking state. Thus, when the outer ring 111c is rotated, the connecting ring 111b will not rotate with the outer ring 111c, so that the locking assembly 111 can be switched between the first locking state and the first unlocking state, and finally, as shown in FIG4 , the overall structure 200a is inserted to the bottom. In other words, the second positioning groove 103 can realize the pre-fixation between the connecting ring 111b and the connecting member 100 in the locking assembly 111, and then the driving torque can be applied to the outer ring 111c to realize the switching of the locking assembly 111 between the first locking state and the first unlocking state. This is conducive to improving the convenience of state switching of the locking assembly 111.
本申请第二方面的实施例提出一种心室连接系统，包括心室辅助装置200以及第一方面所述的心室连接装置10，心室辅助装置200包括上壳体210以及与上壳体210顶部连通的入口管220，连接件100套设于入口管220上并与上壳体210连接。An embodiment of the second aspect of the present application proposes a ventricular connection system, including a ventricular assist device 200 and the ventricular connection device 10 described in the first aspect, the ventricular assist device 200 includes an upper shell 210 and an inlet tube 220 connected to the top of the upper shell 210, and the connector 100 is sleeved on the inlet tube 220 and connected to the upper shell 210.
