一种用于闭合血管伤口的系统及方法A system and method for closing a vascular wound

技术领域technical field

本发明涉及血管腔内治疗技术领域，尤其涉及一种用于闭合血管伤口的系统及方法。The present invention relates to the technical field of intravascular treatment, in particular to a system and method for closing a vascular wound.

背景技术Background technique

在经血管腔进行诊断和介入性血管手术时，通常需要在指定的血管壁上开设创口。这一类血管介入操作通常是在众所周知的Seldinger技术基础上进行的。在进行穿刺操作时，套管针依次穿过患者的皮肤、组织以及血管壁，从而构建出进入血管腔的通路。然后通过套管针引入导丝并通过脉管系统导航到所需的治疗部位。在导丝就位的情况下，首先移除套管针，然后可以在导丝上推进引导器护套，直到引导器护套的远端进入血管腔。随着引导器护套适当地定位在管腔内后，导管通过引导器护套引入血管系统，然后使用已存在的血管介入治疗技术对目标治疗位置进行手术。Transluminal diagnostic and interventional vascular procedures often require incisions in the designated vessel wall. This type of vascular intervention is usually performed on the basis of the well-known Seldinger technique. During the puncture operation, the trocar passes through the patient's skin, tissue and blood vessel wall in sequence, thereby constructing a passageway into the blood vessel lumen. A guidewire is then introduced through the trocar and navigated through the vasculature to the desired treatment site. With the guidewire in place, the trocar is first removed and the introducer sheath can then be advanced over the guidewire until the distal end of the introducer sheath enters the vessel lumen. With the introducer sheath properly positioned within the lumen, the catheter is introduced into the vascular system through the introducer sheath, and the target treatment site is then operated on using existing vascular interventional techniques.

在不再需要已建立的血管通路时，首先移除导管和引导器护套，然后通过经皮缝合施加装置进行创口缝合，该装置的远端能够穿过血管穿刺孔并且定位在血管腔内。缝合装置的中间部分能够向远端推进一根或多根针，穿过与进入穿刺部位相邻的血管壁组织。然后使用一根或多根针将缝合线进入创口相对两侧的血管壁，并将缝合装置从组织道中抽出，将缝合线的末端打结。在缝合线末端通过手动打结并且将线结沿组织道向下推进，直到将它定位在血管壁的外膜表面上。另一种创口缝合方式是用夹具或锁定片将缝合线固定在一起，该夹具或锁定片以手动推进的方式穿过组织后定位在穿刺部位旁边。然而，手动打结或单独的夹持构件进行创口缝合是困难的、耗时的，并且如果操作不正确，会产生额外的不良影响，还可能导致创口无法实现有效闭合。When the established vascular access is no longer needed, the catheter and introducer sheath are first removed and the wound sutured by a percutaneous suture application device, the distal end of which can be passed through the vessel puncture hole and positioned within the vessel lumen. The intermediate portion of the suturing device is capable of advancing one or more needles distally through the tissue of the vessel wall adjacent to the entry puncture site. The suture is then inserted into the vessel wall on opposite sides of the wound using one or more needles, the suture device is withdrawn from the tissue tract, and the ends of the suture are knotted. The suture ends are tied manually and the knot is advanced down the tissue tract until it is positioned on the adventitial surface of the vessel wall. Another way to close the wound is to hold the sutures together with clips or locking tabs that are manually advanced through the tissue and positioned next to the puncture site. However, manual knotting or a separate gripping member for wound closure is difficult, time-consuming, and, if performed incorrectly, has additional adverse effects and may result in ineffective wound closure.

公开号为CN109199485A的专利文献公开了一种用于使缝合线穿引通过组织的外科器械，所述外科器械包括第一钳口和第二钳口以及针，所述第一钳口和第二钳口设置在细长轴的远侧端部上，所述针能够沿穿过第一钳口的外侧壁的纵向通道选择性地进行移动。第一钳口具有被配置成安置可移除和可置换的缝合线盒的腔体。缝合线盒可连接到缝合线盒支架上，该缝合线盒支架在使用外科器械之前被移除，使得针朝远侧推进，从而使连接在缝合线盒支架上的缝合线穿过患者体内的组织。当针朝近侧回缩时，将后续的缝合线部分装载到针上。在缝合线穿过患者体内的组织时，钳口保持在身体中。该专利无法在完成组织的穿刺操作后快速的形成线结，不利于在完成介入手术后快速闭合创口。Patent document publication number CN109199485A discloses a surgical instrument for threading a suture through tissue, the surgical instrument comprising first and second jaws and a needle, the first and second jaws A jaw is provided on the distal end of the elongated shaft, and the needle is selectively movable along a longitudinal passage through the outer sidewall of the first jaw. The first jaw has a cavity configured to accommodate a removable and replaceable suture cartridge. The suture cassette is attachable to a suture cassette holder that is removed prior to use of the surgical instrument, such that the needle is advanced distally, thereby passing the suture attached to the suture cassette holder through the suture cassette holder in the patient. organize. As the needle is retracted proximally, subsequent suture portions are loaded onto the needle. The jaws remain in the body as the suture is passed through tissue in the patient. This patent cannot quickly form a knot after completing the tissue puncture operation, which is not conducive to quickly closing the wound after completing the interventional operation.

因此，本申请提供一种能够限定血管伤口四周的血管壁形态并快速完成缝合线打结操作的用于闭合血管伤口的系统。Therefore, the present application provides a system for closing a vascular wound that can define the morphology of the vascular wall around the vascular wound and quickly complete the suture knotting operation.

具体实施方式Detailed ways

下面结合附图进行详细说明。The following detailed description is given in conjunction with the accompanying drawings.

实施例1Example 1

本申请还提供一种用于闭合血管伤口的系统，其可以包括闭合主体1、导丝鞘管2、调节组件3和缝合单元4。The present application also provides a system for closing a vascular wound, which may include aclosing body 1 , a guide wire sheath 2 , anadjustment assembly 3 and asuturing unit 4 .

根据一种具体的实施方式，闭合主体包括导丝鞘管2、调节组件3和缝合单元4。导丝鞘管2按照部分管体插入调节组件3的本体腔室内的方式与调节组件3连接。缝合单元4设置在调节组件3的本体腔室靠近导丝鞘管2的一端。在进行穿刺操作和缝合操作时，首先，带有针芯的穿刺针在医护人员的控制下依次穿过皮肤、组织和血管壁后插入到血管腔中。导丝沿穿刺针的针管进入血管腔内部。在导丝部分置入血管腔内后，拔出穿刺针，并且将闭合主体1的导丝鞘管2沿导丝置入血管腔内。调节组件3能够对血管伤口进行封堵，同时调节组件3能够通过夹持血管伤口周围的血管壁的方式限定血管壁的形态，使得血管伤口周围的血管壁能够保持一个稳定且平整的形态，从而方便缝合单元4的缝合针线能够沿预设的弧形穿刺路径以环绕血管伤口区域的方式完成缝合针线穿过血管壁的穿刺操作，从而构建出能够闭合血管伤口的呈“U型荷包形态”的线结圈。缝合单元4构建的线结圈能够在完成介入手术后，医护人员通过推结器推动线结圈的线结逐渐靠近血管外壁的方式缩小构成线结圈的缝合线42的长度，使得血管伤口两侧的血管壁在缝合线42的拉动下发生相互靠近的运动，从而实现伤口的闭合。According to a specific embodiment, the closure body includes a guide wire sheath 2 , anadjustment assembly 3 and asuturing unit 4 . The guide wire sheath 2 is connected to theadjustment assembly 3 in a manner that a part of the tube body is inserted into the body cavity of theadjustment assembly 3 . Thesuturing unit 4 is disposed at one end of the body chamber of theadjustment assembly 3 close to the guide wire sheath 2 . During the puncture operation and the suture operation, firstly, the puncture needle with the needle core is inserted into the blood vessel lumen after passing through the skin, the tissue and the blood vessel wall in sequence under the control of the medical staff. The guide wire is inserted into the lumen of the blood vessel along the needle tube of the puncture needle. After the guide wire is partially inserted into the blood vessel lumen, the puncture needle is pulled out, and the guide wire sheath 2 that closes themain body 1 is placed into the blood vessel lumen along the guide wire. Theregulating component 3 can seal the blood vessel wound, and at the same time theregulating component 3 can limit the shape of the blood vessel wall by clamping the blood vessel wall around the blood vessel wound, so that the blood vessel wall around the blood vessel wound can maintain a stable and flat shape, thereby It is convenient for the suture needle thread of thesuture unit 4 to complete the puncture operation of the suture needle thread through the blood vessel wall along the preset arc-shaped puncture path in a manner of surrounding the blood vessel wound area, so as to construct a “U-shaped purse shape” that can close the blood vessel wound. Wire knot loop. The knot loop constructed by thesuturing unit 4 can reduce the length of thesuture 42 forming the knot loop by pushing the knot of the knot loop with the knot pusher to gradually approach the outer wall of the blood vessel after the interventional operation is completed, so that the two sides of the vascular wound can be shortened. Under the pulling of thesuture 42, the lateral vessel walls move toward each other, thereby achieving the closure of the wound.

如图2所示，导丝鞘管2可以包括鞘管主体21和拇指板22。其中，鞘管主体21插入调节组件3的管体的轴向上端连接有控制鞘管主体21沿其轴线方向进行移动的拇指板22。具体地，拇指板22按照贯穿调节主体33的方式与安装在调节主体33内部的鞘管主体21的端部进行连接，从而通过推动拇指板22沿调节主体33的轴线方向进行往复平移的方式实现导丝鞘管2与调节组件3之间的相对平移。医护人员在进行操作时能够通过控制拇指板22发生定向平移，使得导丝鞘管2带动球囊31进行上提操作，使得置入血管腔中的球囊31能够在发生体积膨胀的情况下贴附在血管伤口上，从而实现球囊31对血管伤口的封堵。优选地，鞘管主体21的管体上安装有能够对血管伤口进行封堵的球囊31。鞘管主体21靠近球囊31的管体侧面还开设有能够排出血液的侧孔23。在未发生膨胀的球囊31跟随鞘管主体21伸入到血管腔中时，球囊31会对血管造成一定程度的堵塞，导致血液会顺着鞘管主体21上的侧孔23流入到调节主体33。因此，鞘管主体21与拇指板22连接的端部还设有能够方便观察和排出血液的导引外管24。优选地，导引外管24的末端可以连接一个方便观察是否出现血液外流的透明储血囊。优选地，导引外管24能够跟随拇指板22在调节主体33上发生平移，使得导引外管24能够跟随鞘管主体21的运动而发生相同的平移，避免导引外管24与鞘管主体21发生分离，造成鞘管主体21内引出的血液污染装置其他部件。在将导丝鞘管2置入血管腔的过程中，医护人员通过观察与导引外管24的末端连通的透明储血囊中是否突然出现呈喷射状的血液的方式判断球囊31是否已进入到血管腔中。在球囊31进入血管腔而侧孔23没有完全进入血管腔时，鞘管主体22虽然也能够引出血流，但是进入导引外管24的血液在管道内的压力并不高，无法出现血液喷射的情况。当侧孔23完全进入到血管腔时，随着血管波动，侧孔23中血液的进入速度和压力激增，导致导引外管24中的血液能够喷涌而出，使得在透明储血囊中观察到血液喷射的情况。因此，医护人员在进行鞘管主体22的插入操作时，可以根据透明储血囊中出现血液喷射的现象来判断鞘管主体22的插入操作是否成功。As shown in FIG. 2 , the guide wire sheath 2 may include asheath body 21 and athumb plate 22 . Wherein, the axial upper end of the tube body of the sheath tubemain body 21 inserted into theadjustment assembly 3 is connected with athumb plate 22 for controlling the movement of the sheath tubemain body 21 along the axial direction thereof. Specifically, thethumb plate 22 is connected with the end of thesheath tube body 21 installed inside theadjustment body 33 in a manner of penetrating theadjustment body 33 , so as to realize the reciprocating translation by pushing thethumb plate 22 along the axial direction of theadjustment body 33 Relative translation between the guide wire sheath 2 and theadjustment assembly 3 . During the operation, the medical staff can control thethumb plate 22 to perform directional translation, so that the guide wire sheath 2 drives theballoon 31 to carry out the lifting operation, so that theballoon 31 placed in the vascular cavity can be attached to the vascular cavity under the condition of volume expansion. It is attached to the vascular wound, so as to realize the occlusion of the vascular wound by theballoon 31 . Preferably, aballoon 31 capable of sealing a blood vessel wound is installed on the tubular body of thesheath body 21 . Aside hole 23 capable of draining blood is further opened on the side surface of thesheath body 21 close to theballoon 31 . When theuninflated balloon 31 follows thesheath body 21 into the blood vessel lumen, theballoon 31 will block the blood vessel to a certain extent, so that blood will flow into the regulator along theside hole 23 on thesheath body 21main body 33.
