背景技术Background technique
介入手术中，通常利用控制手柄来操作导管组件，将装载于导管组件的介入器械输送至病灶部位，而后将导管组件中包裹介入器械的外鞘管回撤、即暴露介入器械，介入器械的释放可以是利用自膨方式，也可以是利用球囊导管由内而外的将介入器械扩张。In interventional surgery, the control handle is usually used to operate the catheter assembly, and the interventional instrument loaded in the catheter assembly is transported to the lesion site, and then the outer sheath wrapping the interventional instrument in the catheter assembly is withdrawn, that is, the interventional instrument is exposed, and the interventional instrument is released. It can be self-expanding or a balloon catheter can be used to expand the interventional device from the inside out.

参见图1，显示了心脏介入手术中，主动脉弓部位的器械姿态示意图，为了适应该部位的生理结构，导管组件30的远端呈现明显的弯曲转折，通常会借助调弯手段主动干预导管组件30的远端姿态，介入器械8基本就位后，无论是自膨或球扩方式，均是通过回撤外鞘管310的方式暴露介入器械，以便于介入器械8的完全释放。Referring to Figure 1, a schematic diagram of the posture of the instrument at the aortic arch during cardiac interventional surgery is shown. In order to adapt to the physiological structure of this site, the distal end of the catheter assembly 30 exhibits an obvious bend. Usually, bending means are used to actively intervene in the catheter assembly 30. In the distal posture, after the interventional instrument 8 is basically in place, whether it is self-expansion or bulb expansion, the interventional instrument is exposed by withdrawing the outer sheath 310 to facilitate the complete release of the interventional instrument 8 .
导管组件的近端连接并受控于控制手柄，受控制手柄体积(长度)的限制，各管件的相对活动行程有限，因此在回撤外鞘管的过程中，外鞘管的远端一般仍处在主动脉弓部位，对于导管组件整体而言，各部位的刚度(暴露于外鞘管的部位以及仍处在外鞘管内的部位)差异较大，空间姿态不再稳定，可能需要重新调整，给手术带来了不必要的繁琐操作。尤其在针对球扩方式释放介入器械的场景中，容许外鞘管快速回撤，以期提高效率。The proximal end of the catheter assembly is connected and controlled by the control handle. Limited by the volume (length) of the control handle, the relative movable stroke of each pipe fitting is limited. Therefore, during the process of withdrawing the outer sheath, the distal end of the outer sheath is generally still In the aortic arch, for the entire catheter assembly, the stiffness of each part (the part exposed to the outer sheath and the part still inside the outer sheath) is quite different, and the spatial posture is no longer stable, and may need to be readjusted for surgery. It brings unnecessary cumbersome operations. Especially in scenarios where interventional devices are released by ball expansion, the outer sheath is allowed to be quickly withdrawn in order to improve efficiency.
参见图2～图5，本申请一实施例提供了一种基于直接驱动外鞘管310的控制手柄，包括：Referring to Figures 2 to 5, one embodiment of the present application provides a control handle based on direct driving of the outer sheath 310, including:
外壳200，具有空间上的轴向，以及在轴向上相对的远端和近端，外壳200具有轴向贯通的穿引通道201；The housing 200 has an axial direction in space and a distal end and a proximal end that are opposite in the axial direction. The housing 200 has an axially penetrating through channel 201;
连接套210，固定在外壳200内且绕穿引通道201布置，连接套210的远端侧供外鞘管310插接配合；The connecting sleeve 210 is fixed in the shell 200 and arranged around the penetration channel 201. The distal side of the connecting sleeve 210 is used for the outer sheath tube 310 to be plugged and matched;
定位件220，活动安装在外壳200内，定位件220具有干涉穿引通道201的锁定位以及释放穿引通道201的解锁位；The positioning piece 220 is movably installed in the housing 200. The positioning piece 220 has a locking position for interfering with the threading channel 201 and an unlocking position for releasing the threading channel 201;
驱动件230，与定位件220传动配合带动定位件220切换位置。The driving member 230 cooperates with the positioning member 220 to drive the positioning member 220 to switch positions.
本申请中针对导管组件30中的外鞘管310，独立配置控制手柄，整个控制手柄中带有穿引通道201，一方面用以插入对接外鞘管310，另一方面供导管组件30中的其他管件经由外鞘管近端延伸出以后、滑动的穿过控制手柄，就整个介入器械输送系统1而言具有控制手柄9，而外鞘管310的控制手柄可视为副手柄20(下文亦称副手柄)，其余管件的控制手柄可视为主手柄10(下文亦称主手柄，此处的主、副理解为相对概念)。In this application, the outer sheath 310 in the catheter assembly 30 is independently configured with a control handle. The entire control handle is provided with a through passage 201. On the one hand, it is used to insert the docking outer sheath 310, and on the other hand, it is used for After other pipe fittings extend through the proximal end of the outer sheath tube and slide through the control handle, the entire interventional instrument delivery system 1 has a control handle 9, and the control handle of the outer sheath tube 310 can be regarded as the auxiliary handle 20 (hereinafter also referred to as the auxiliary handle 20). (called the auxiliary handle), and the control handles of the other pipe fittings can be regarded as the main handle 10 (hereinafter also referred to as the main handle, and the main and auxiliary here are understood as relative concepts).
将副手柄20与主手柄10分别设置，可进一步提高外鞘管控制的灵活程度，更为重要的是外鞘管的行程不再受主手柄长度的限制，在回撤外鞘管时，可将外鞘管的远端部位也撤出主动脉弓，尽可能的减少对其余管件空间姿态的影响。Setting the auxiliary handle 20 and the main handle 10 separately can further improve the flexibility of the outer sheath control. More importantly, the stroke of the outer sheath is no longer limited by the length of the main handle. When withdrawing the outer sheath, the outer sheath can be The distal part of the outer sheath is also withdrawn from the aortic arch to minimize the impact on the spatial posture of the remaining tubing.
其中，定位件220与驱动件230的设置主要是为了调节以及锁定副手柄20与主手柄10的相对位置，避免外鞘管310相对于其他管件发生不必要的滑移错位，以降低安全隐患。Among them, the positioning member 220 and the driving member 230 are mainly provided to adjust and lock the relative position of the auxiliary handle 20 and the main handle 10 to avoid unnecessary slippage and dislocation of the outer sheath tube 310 relative to other pipe parts, so as to reduce safety risks.
在配合使用时，除外鞘管310的其他管件均处在穿引通道201内，因定位件220干涉穿引通道201也意味着可以对其他管件施加作用力，继而锁定副手柄20与其他管件的相对位置，同理释放穿引通道201则意味着降低或彻底解除对其他管件施加作用力，允许副手柄20带动外鞘管310与其他管件相对滑动，驱动件230与定位件220之间可以是一体结构，分体固定，或传动配合，用以带动定位件220在锁定位和解锁位之间切换。When used together, all other pipe fittings except the sheath tube 310 are located in the threading channel 201. Since the positioning member 220 interferes with the threading channel 201, it also means that it can exert force on other pipe fittings, thereby locking the auxiliary handle 20 and other pipe fittings. Relative position, in the same way, releasing the penetration channel 201 means reducing or completely releasing the force exerted on other pipe fittings, allowing the auxiliary handle 20 to drive the outer sheath tube 310 to slide relative to other pipe fittings, and the driving member 230 and the positioning member 220 can be The integrated structure, split fixation, or transmission matching is used to drive the positioning member 220 to switch between the locking position and the unlocking position.
本实施例中并不严格限制定位件和驱动件相对于副手柄的运动方向，作为定位件而言，至少具有沿穿引通道径向的运动分量，以改变对其他管件的作用力或径向相对位置。In this embodiment, the movement direction of the positioning member and the driving member relative to the auxiliary handle is not strictly limited. As a positioning member, it at least has a movement component along the radial direction of the passage to change the force or radial direction of other pipe parts. relative position.

单向阀芯整体而言可浮动设置，限位杆261活动安装且位置受限于第一管接头211，可限制密封片262的行程，尤其在开放状态，若密封片262行程过大，可能会直接封堵第一排气孔2102。例如第一管接头211的内壁设有环绕在限位杆外周的卡环2112，流体间隙位于卡环2112的外周与第一管接头211的内壁之间；The one-way valve core can be set to float as a whole. The limit rod 261 is movably installed and its position is limited by the first pipe joint 211, which can limit the stroke of the sealing plate 262, especially in the open state. If the stroke of the sealing plate 262 is too large, it may The first exhaust hole 2102 will be blocked directly. For example, the inner wall of the first pipe joint 211 is provided with a snap ring 2112 surrounding the outer periphery of the limiting rod, and the fluid gap is located between the outer periphery of the snap ring 2112 and the inner wall of the first pipe joint 211;

在另一实施例中，参阅图9～图10b，单向阀芯整体而言也可以固定设置，限位杆261固定安装，仅依靠密封片262边缘的形变开放或封闭流体间隙。例如第一管接头211的内壁设有环绕在限位杆外周的卡环2112，流体间隙位于卡环2112的外周与第一管接头211的内壁之间；In another embodiment, referring to Figures 9 to 10b, the one-way valve core as a whole can also be fixedly installed, the limiting rod 261 is fixedly installed, and the fluid gap is opened or closed only by the deformation of the edge of the sealing piece 262. For example, the inner wall of the first pipe joint 211 is provided with a snap ring 2112 surrounding the outer periphery of the limiting rod, and the fluid gap is located between the outer periphery of the snap ring 2112 and the inner wall of the first pipe joint 211;

以下实施例中提供了关于定位件的具体结构，例如参阅图8～图13，定位件220为弹性爪，弹性爪的一端固定于连接套210，另一端为沿连接套径向摆动的自由端2201。The specific structure of the positioning member is provided in the following embodiments. For example, refer to Figures 8 to 13. The positioning member 220 is an elastic claw. One end of the elastic claw is fixed to the connecting sleeve 210, and the other end is a free end that swings along the radial direction of the connecting sleeve. 2201.
驱动件230与弹性爪221的自由端2201联动，使得自由端2201沿连接套径向向内(即干涉穿引通道201、抱紧内部管件)运动，或释放弹性爪221，弹性爪221具有复位趋势(即远离穿引通道、减小对内部管件的作用)，容许副手柄20相对内部管件滑动，改变外鞘管远端的相对位置。The driving member 230 is linked with the free end 2201 of the elastic claw 221, so that the free end 2201 moves radially inward along the connecting sleeve (i.e., interferes with the passage 201 and holds the internal pipe fittings tightly), or releases the elastic claw 221, which has a reset function. trend (that is, moving away from the passageway and reducing the effect on the internal pipe fittings), the auxiliary handle 20 is allowed to slide relative to the internal pipe fittings to change the relative position of the distal end of the outer sheath.
弹性爪221的固定端2202与连接套210之间可以是分体固定，还可以是弹性爪与连接套210为一体结构。The fixed end 2202 of the elastic claw 221 and the connecting sleeve 210 can be fixed separately, or the elastic claw and the connecting sleeve 210 can be an integral structure.
连接套210整体上为管状，在其管壁部位可带有U形镂空区2204，U形镂空区环绕的部位即为弹性爪221，弹性爪221整体上为条状，相对而言、弹性爪的固定端2202在远端侧，自由端2201在近端侧。为了获得比较均匀的束紧力，弹性爪可配置多个，例如弹性爪为二～六个(例如四个)，沿连接套210周向分布。The connecting sleeve 210 is tubular as a whole, and can have a U-shaped hollow area 2204 on the tube wall. The part surrounded by the U-shaped hollow area is the elastic claw 221. The elastic claw 221 is strip-shaped as a whole. Relatively speaking, the elastic claw 221 is in the shape of a strip. The fixed end 2202 is on the distal side, and the free end 2201 is on the proximal side. In order to obtain a relatively uniform tightening force, multiple elastic claws may be configured, for example, two to six elastic claws (for example, four), distributed along the circumferential direction of the connecting sleeve 210 .
为了同步驱动各弹性爪，简化部件结构，驱动件230为筒状且滑动套设在连接套210的外周，驱动件230的内壁作用于弹性爪。In order to drive each elastic claw synchronously and simplify the component structure, the driving member 230 is cylindrical and a sliding sleeve is provided on the outer periphery of the connecting sleeve 210. The inner wall of the driving member 230 acts on the elastic claws.
驱动件230的滑动方向即连接套210的长度方向，驱动件230运动至不同位置时，对弹性爪施加的径向力会发生变化，使定位件220在锁定位和解锁位之间切换，为了使弹性爪获得较为均匀的径向力变化趋势，弹性爪和驱动件230彼此可通过斜面配合，例如沿连接套210的径向，弹性爪221的外侧设有导向斜台2203，驱动件230的内壁作用于导向斜台2203。The sliding direction of the driving member 230 is the length direction of the connecting sleeve 210. When the driving member 230 moves to different positions, the radial force exerted on the elastic claw will change, causing the positioning member 220 to switch between the locking position and the unlocking position. In order to In order to obtain a more uniform radial force change trend of the elastic claw, the elastic claw and the driving member 230 can cooperate with each other through an inclined plane. For example, along the radial direction of the connecting sleeve 210, a guide ramp 2203 is provided on the outside of the elastic claw 221, and the driving member 230 can The inner wall acts on the guide ramp 2203.
沿连接套210径向，导向斜台2203的高度有远端至近端逐渐变高，在不考虑驱动件内壁变化时，驱动件230向近端运动时，即可使得弹性爪221的自由端2201进一步向内运动，增加与内部管件的作用力，直至锁紧。为了实现缓冲、保护，以及获得较好的束紧、密封效果，在弹性爪221于内部管件之间可设置弹性部件，在副手柄20滑动时还可以获得阻尼效果，改善操作体验。例如连接套210的内部设有弹性衬管240，弹性爪221作用在弹性衬管的外壁、通过挤压弹性衬管240干涉穿引通道201。Along the radial direction of the connecting sleeve 210, the height of the guide ramp 2203 gradually increases from the distal end to the proximal end. When the change of the inner wall of the driving member is not considered, when the driving member 230 moves toward the proximal end, the free end of the elastic claw 221 can be 2201 moves further inward, increasing the force against the internal pipe until it is locked. In order to achieve buffering, protection, and obtain better tightening and sealing effects, elastic components can be provided between the elastic claws 221 and the internal pipes. When the auxiliary handle 20 slides, a damping effect can also be obtained to improve the operating experience. For example, an elastic lining tube 240 is provided inside the connecting sleeve 210 , and the elastic claws 221 act on the outer wall of the elastic lining tube to interfere with the penetration channel 201 by squeezing the elastic lining tube 240 .
在穿入内部管件时，弹性爪221向内挤压弹性衬管240，并通过弹性衬管240箍紧内部管件。为了避免不必要的松脱，弹性衬管240可采用过盈的方式插入连接套内部。为了进一步轴向定位，弹性衬管240的远端延伸出连接套210，在延伸出的部位上设有径向外凸的定位台阶2401，沿轴向，定位台阶2401与连接套210的端面和/或外壳200的内壁轴向定位配合。When penetrating the inner pipe, the elastic claws 221 press the elastic liner 240 inward and tighten the inner pipe through the elastic liner 240. In order to avoid unnecessary loosening, the elastic liner 240 can be inserted into the connecting sleeve in an interference manner. For further axial positioning, the distal end of the elastic liner 240 extends out of the connecting sleeve 210, and a radially outwardly protruding positioning step 2401 is provided at the extended part. Along the axial direction, the positioning step 2401 is in contact with the end surface of the connecting sleeve 210 and /or the inner wall of the housing 200 is axially positioned and matched.

The first escape opening 2302 can also be further extended along the radial direction of the connecting sleeve 210. The first escape opening 2302 has a corresponding configuration length according to the sliding stroke of the driving member 230.
为了使驱动件230稳定滑动以及保证必要的结构强度，应具有足够的轴向长度，基于此尚需考虑与第一排气通道的干涉，驱动件230的侧壁设有第二避让口2303，连接套210的侧壁设有与穿引通道201相配合的第一排气孔；沿连接套210的轴向、第二避让口2303的位置与第一排气孔的位置对应。In order for the driving member 230 to slide stably and ensure the necessary structural strength, it should have sufficient axial length.

本申请控制手柄件可独立的操作外鞘管，使外鞘管的运动与内部的其他管件相分离，同时也释放了对主手柄长度的限制，在回撤外鞘管时，可以直接驱动副手柄，且行程足以使得外鞘管的远端脱离主动脉弓，例如副手柄向近端回撤至极限位置时，导管组件中其余管件的远端暴露(解除被外鞘管的束缚)较长的一段，结合调弯场景，当内部管件有调弯管时，该调弯管的远端暴露0～20cm，以副手柄整体行程作为衡量时，行程至少10～40cm，以避让主动脉弓或导管组件远端的调弯部位，便于对介入器械进行调整或其他操作。The control handle piece of this application can independently operate the outer sheath tube, so that the movement of the outer sheath tube is separated from other internal pipe parts. It also releases the restriction on the length of the main handle. When the outer sheath tube is withdrawn, the auxiliary sheath tube can be directly driven. handle, and the stroke is sufficient to make the distal end of the outer sheath tube detach from the aortic arch. For example, when the auxiliary handle is retracted proximally to the extreme position, the distal end of the remaining tubing in the catheter assembly is exposed (released from the outer sheath tube) for a longer period , combined with the bending scenario, when the internal pipe fittings have a bending tube, the distal end of the bending tube is exposed 0 to 20cm. When measured by the overall stroke of the auxiliary handle, the stroke should be at least 10 to 40cm to avoid the aortic arch or the distal end of the catheter assembly The bending part facilitates adjustment or other operations of interventional instruments.
