技术领域Technical field
本公开涉及医疗器械技术领域，具体而言，涉及一种吻合口加固修补片。The present disclosure relates to the technical field of medical devices, and specifically to an anastomotic reinforcing patch.
背景技术Background technique
吻合器的应用极大地推动了现代外科和微创外科的发展，具有里程碑的意义。吻合器可以在切割的同时通过吻合钉对组织钉合，广泛用于肠、胃、肺、胰腺等脏器组织的切割、缝合或吻合。但仅仅通过吻合钉的硬性钉合并不能完全避免吻合口组织的渗漏、出血。这是因为吻合钉为刚性结构，与软组织的柔性不能完全匹配，导致钉孔出现渗漏、出血。此外，由于不同区域的软组织性状存在差异，有些软组织例如肺的强度较低，可能存在吻合口撕裂的风险。为解决上述问题，可以通过将吻合口加固修补片与吻合器联用，使得吻合器切割和封闭创面的同时，将加固修补片固定于创面，封堵吻合钉钉孔，提高创面强度，从而避免创面的渗漏和出血。但是在临床实践中，由于某些特定部位的手术空间狭小，例如盆腔，普通的吻合器无法深入患处为患者进行吻合修补，故此，临床实践中还需要弧形吻合器。The application of staplers has greatly promoted the development of modern surgery and minimally invasive surgery, which is a milestone. The stapler can staple tissues through staples while cutting, and is widely used for cutting, suturing or anastomosis of intestines, stomach, lungs, pancreas and other organs and tissues. However, leakage and bleeding of anastomotic tissue cannot be completely avoided by using rigid staples alone. This is because the staples have a rigid structure and cannot fully match the flexibility of the soft tissue, causing leakage and bleeding in the nail holes. In addition, due to differences in soft tissue properties in different regions, some soft tissues such as the lungs have lower strength and may be at risk of anastomotic tearing. In order to solve the above problems, the anastomotic reinforcement patch can be used in conjunction with the stapler, so that the stapler cuts and seals the wound and at the same time fixes the reinforcement patch to the wound, seals the anastomotic nail holes, improves the strength of the wound, and thus avoids Leakage and bleeding from the wound. However, in clinical practice, due to the small surgical space in some specific parts, such as the pelvic cavity, ordinary staplers cannot penetrate into the affected area to perform anastomotic repair for the patient. Therefore, curved staplers are also needed in clinical practice.

Without further limitation, an element defined by the statement "comprises a..." does not exclude the presence of other identical elements in the goods or devices including the stated element.
在相关技术中，吻合口加固修补片包括：背衬、修补片和缝合线。缝合线将背衬和修补片连接在一起，使背衬和修补片成为一个整体，且两根缝合线具有较长的牵引段。使用时，将修补片安装至吻合器上，再将吻合器前部伸入体腔内，抵达病灶。闭合吻合器钳口，使钳口夹持住待吻合组织。然后抽拉牵引段，使修补片与背衬完全分离。由于缝合线与背衬在前端有固定连接点，此时背衬受缝合线拉扯后撤。接下来，击发吻合器，利用吻合器切割组织，并形成吻合口；吻合器在形成吻合口的同时将修补片固定至吻合口处，并切割为两部分。然后松解吻合器钳口,接着向病人体外撤出吻合器，并继续抽拉牵引段，取出背衬。从而完成操作，并实现修补片对吻合口修补的目的。In the related art, an anastomotic reinforcement patch includes: a backing, a patch, and a suture. The sutures connect the backing and the patch together so that the backing and the patch become a single unit, and the two sutures have longer traction sections. During use, the patch is installed on the stapler, and then the front part of the stapler is extended into the body cavity to reach the lesion. Close the jaws of the stapler so that the jaws clamp the tissue to be anastomotic. Then pull the traction section to completely separate the patch from the backing. Since the suture and the backing have a fixed connection point at the front end, the backing is pulled back by the suture at this time. Next, the stapler is fired, and the stapler is used to cut the tissue and form an anastomosis; while forming the anastomosis, the stapler fixes the patch to the anastomosis and cuts it into two parts. Then loosen the jaws of the stapler, then withdraw the stapler outside the patient's body, continue to pull the traction section, and remove the backing. This completes the operation and achieves the purpose of repairing the anastomosis with the patch.
常用腔镜吻合器主要是用于腹腔内的手术，吻合器经穿刺器进入腹腔，抵达病灶。这一类吻合器的前端为直线型的结构。但由于某些特定部位的手术空间狭小，例如在盆腔内的直肠肿瘤手术，采用直线型的吻合器虽然可以进入盆腔，但是由于其切割线为直线型，无法深入盆底切割肿瘤。对于这类手术，尤其是低位直肠肿瘤手术，采用弧形吻合器进行病灶切除，而采用吻合器就存在吻合口钉孔出血及发生吻合口缝合不严的风险。Commonly used laparoscopic staplers are mainly used for intra-abdominal surgeries. The staplers enter the abdominal cavity through the puncture device and reach the lesion. The front end of this type of stapler has a linear structure. However, due to the small surgical space in some specific parts, such as rectal tumor surgery in the pelvis, although a linear stapler can be used to enter the pelvic cavity, its cutting line is linear and cannot penetrate the pelvic floor to cut the tumor. For this type of surgery, especially for low rectal tumors, arc-shaped staplers are used for lesion resection. However, the use of staplers involves the risk of anastomotic nail hole bleeding and lax anastomotic suturing.
有鉴于此，下面结合附图详细说明本公开的可选实施例。In view of this, optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
本公开实施例提供一种吻合口加固修补片200，包括：背衬100、端帽103、修补片200、缝合线310以及牵引线320。The embodiment of the present disclosure provides an anastomotic reinforcement patch 200, which includes: a backing 100, an end cap 103, a patch 200, a suture 310 and a traction thread 320.

The stapler can repair the anastomosis in a small space to protect the fragile tissue from being torn, thereby strengthening the anastomosis and reducing the risk of anastomotic bleeding, exudation, etc.
所述端帽103设置于所述背衬100的所述第一面，所述端帽103的圆弧端与所述背衬100的第一端101固定连接，所述端帽103可折叠使所述端帽103与背衬100重合，所述端帽103用于限制所述吻合口加固修补片200与所述弧形吻合器连接。The end cap 103 is disposed on the first surface of the backing 100. The arc end of the end cap 103 is fixedly connected to the first end 101 of the backing 100. The end cap 103 is foldable. The end cap 103 overlaps the backing 100, and the end cap 103 is used to restrict the anastomosis reinforcement patch 200 from being connected to the arc-shaped stapler.

The end cap 103 is sleeved with an arc-shaped stapler and wraps the end of the arc-shaped stapler to avoid arc-shaped anastomosis. The end of the device is in direct contact with human tissue.
所述缝合线310设置于所述背衬100上，用于将所述背衬100与所述修补片200和所述端帽103连接，如图2所示，所述缝合线310在所述背衬100上设置为封闭环形。The suture line 310 is provided on the backing 100 for connecting the backing 100 to the patch 200 and the end cap 103. As shown in FIG. 2, the suture line 310 is on the backing 100. The backing 100 is provided in a closed ring shape.
在一些实施例中，所述缝合线310的至少部分与所述端帽103连接，以避免端帽103与修补片200之间存在缝隙使吻合器露出。其中，所述缝合线310使端帽103和修补片200与背衬100可拆卸地连接。In some embodiments, at least part of the suture 310 is connected to the end cap 103 to avoid a gap between the end cap 103 and the patch 200 to expose the stapler. The sutures 310 detachably connect the end cap 103 and the patch 200 to the backing 100 .
具体地，所述端帽103与所述背衬100具有展开状态和折叠状态，如图1、图2所示，当所述缝合线310未将端帽103与所述背衬100缝合时，所述端帽103与所述背衬100为展开状态，此时端帽103的端部与所述背衬100的第一段连接，端帽103与所述背衬100补充和；当所述缝合线310将端帽103与所述背衬100缝合时，所述端帽103与背衬100第一端101的部分重合，此时，所述端帽103与所述背衬100为折叠状态。Specifically, the end cap 103 and the backing 100 have an unfolded state and a folded state. As shown in Figures 1 and 2, when the suture line 310 does not sew the end cap 103 and the backing 100, The end cap 103 and the backing 100 are in an unfolded state. At this time, the end of the end cap 103 is connected to the first section of the backing 100, and the end cap 103 and the backing 100 are complementary; when the When the suture line 310 sews the end cap 103 to the backing 100, the end cap 103 overlaps with the first end 101 of the backing 100. At this time, the end cap 103 and the backing 100 are in a folded state. .
所述端帽103至少具有朝向第二端102方向的单侧开口，所述端帽103用于容纳弧形吻合器的端部，以使弧形吻合器的端部与所述端帽103抵接并包裹在所述端帽103内，避免弧形吻合器端部直接接触人体组织；同时避免在弧形吻合器在狭窄空间内工作时，因碰触体内腔壁而导致的修补片200发生翻卷。The end cap 103 has at least one unilateral opening toward the second end 102. The end cap 103 is used to accommodate the end of the arc-shaped stapler, so that the end of the arc-shaped stapler abuts against the end cap 103. Connected and wrapped in the end cap 103 to prevent the end of the arc-shaped stapler from directly contacting human tissue; at the same time, it avoids the occurrence of the patch 200 caused by touching the wall of the body cavity when the arc-shaped stapler is working in a narrow space. Roll over.
需要注意的是，使用带有端帽103的吻合口加固修补片，有助于准确固定修补片200的位置，并避免修补片200发生翻卷。而对于操作空间更为充足的开放手术用的吻合器，也可以使用不带有端帽103的吻合口加固修补片。这是因为对于开放式手术，操作空间大，可以使用带端帽103或不带端帽103的吻合口加固修补片。It should be noted that using an anastomotic reinforcement patch with an end cap 103 helps to accurately fix the position of the patch 200 and prevent the patch 200 from rolling over. For staplers for open surgery that have more ample operating space, an anastomotic reinforcing patch without an end cap 103 can also be used. This is because for open surgery, the operating space is large, and an anastomotic reinforcing patch with or without the end cap 103 can be used.
在一些实施例中，所述修补片200沿所述背衬100的弯曲方向延伸，且所述修补片200的至少部分收容至所述端帽103内部。In some embodiments, the patch 200 extends along the bending direction of the backing 100 , and at least part of the patch 200 is received inside the end cap 103 .
具体地，所述背衬100的第一面上设置修补片200，所述缝合线310用于将所述修补片200与所述背衬100缝合，使所述修补片200与所述背衬100为可拆卸连接。所述背衬100的第一端101设置有端帽103，用于收容至少一部分所述修补片200。Specifically, a patch patch 200 is provided on the first surface of the backing 100, and the suture line 310 is used to sew the patch patch 200 and the backing 100, so that the patch patch 200 and the backing 100 are 100 for detachable connection. The first end 101 of the backing 100 is provided with an end cap 103 for receiving at least a portion of the patch 200 .
在一些实施例中，缝合线310的一端以不可拆卸的方式与背衬缝合，用于在缝合线310被拆卸后，仍与背衬100相连，从而将背衬100从体腔内牵拉至体外。若缝合线310完全与背衬100分离，可通过其它医疗器械，例如：医用钳或夹子，将背衬100取出体外。In some embodiments, one end of the suture 310 is non-detachably sewn to the backing, and is used to remain connected to the backing 100 after the suture 310 is detached, thereby pulling the backing 100 from the body cavity to the outside of the body. . If the suture 310 is completely separated from the backing 100, the backing 100 can be taken out of the body using other medical instruments, such as medical forceps or clamps.
在一些实施例中，所述缝合线310的至少部分与所述端帽103连接，所述修补片200的至少部分延伸至所述端帽103内部，用于导引弧形吻合器进入端帽103。其中，所述缝合线310使端帽103以可拆卸地方式设置于背衬100上。当拆卸缝合线310时，端帽103与背衬100的缝线连接能够被松解开，从而释放被套接的弧形吻合器端部。In some embodiments, at least part of the suture 310 is connected to the end cap 103, and at least part of the patch 200 extends into the end cap 103 for guiding an arc-shaped stapler into the end cap. 103. Wherein, the suture 310 enables the end cap 103 to be detachably disposed on the backing 100 . When the suture 310 is removed, the suture connection of the end cap 103 to the backing 100 can be loosened, thereby releasing the encased arcuate stapler end.
在一些实施例中，所述吻合口加固修补片200还包括牵引线320，所述牵引线320套设于临近所述第二端102的所述缝合线310上，在外力作用下拖拽所述牵引线320，可以带动所述缝合线310与所述背衬100分离。In some embodiments, the anastomosis reinforcement patch 200 further includes a traction wire 320, which is set on the suture 310 adjacent to the second end 102 and drags the suture 310 under the action of external force. The pulling line 320 can drive the suture line 310 to separate from the backing 100 .
具体地，在外力作用下拉动所述牵引线320，可以使所述缝合线310脱离所述背衬100，进一步地，使端帽103由折叠状态转换至展开状态，所述修补片200与所述背衬100分离。此时，所述修补片200与所述端帽103处于展开状态，所述修补片200与所述背衬100相对独立，吻合口加固修补片200修补至病人患处，背衬100和弧形吻合器可以抽出病人体外。Specifically, by pulling the traction line 320 under the action of external force, the suture line 310 can be separated from the backing 100, and further, the end cap 103 can be converted from the folded state to the unfolded state, and the repair piece 200 can be connected with the backing 100. The backing 100 separates. At this time, the patch 200 and the end cap 103 are in an unfolded state, the patch 200 is relatively independent of the backing 100, the anastomotic reinforcement patch 200 is repaired to the patient's affected area, and the backing 100 is consistent with the arc. The device can be withdrawn from the patient's body.
在一些实施例中，如图3所示，弧形的修补片200弯曲延伸方向的两侧边具有相同的圆心和圆心角角度，在实际应用中，为使得修补片200与弧形吻合器具有更高的匹配度，现对修补片200的参数加以限定。In some embodiments, as shown in FIG. 3 , both sides of the curved extension direction of the arc-shaped patch 200 have the same center and center angle. In practical applications, in order to make the patch 200 and the arc-shaped stapler have the same For a higher degree of matching, the parameters of the patch 200 are now limited.
具体地，将所述修补片200上两圆弧的圆心在空间上命名为(a，b)，以圆心为基准，所述修补片200的内圆弧的半径长度为r，r＝15mm-40mm；所述修补片200的宽度为w，w＝5mm-20mm；所述弧形结构的圆心角角度为θ，θ＝80°-180°；例如，圆心角角度θ可以为90°、100°、110°、120°、130°、140°、150°、160°或170°。所述修补片200在此限定下，可以满足多使用场景下与弧形吻合器的配合精度标准，便于临床实践中医生对吻合口加固修补片200的控制，提高手术精确性和时效性。Specifically, the centers of the two arcs on the patch 200 are spatially named (a, b). Based on the center of the circle, the radius length of the inner arc of the patch 200 is r, r=15mm- 40mm; the width of the patch 200 is w, w=5mm-20mm; the central angle of the arc-shaped structure is θ, θ=80°-180°; for example, the central angle θ can be 90°, 100 °, 110°, 120°, 130°, 140°, 150°, 160° or 170°. Under this limitation, the patch 200 can meet the matching accuracy standard with the arc-shaped stapler in multiple usage scenarios, which facilitates doctors' control of the anastomotic reinforcement patch 200 in clinical practice and improves surgical accuracy and timeliness.
在一些实施例中，所述缝合线310包括：第一缝合线311以及第二缝合线312。In some embodiments, the suture line 310 includes: a first suture line 311 and a second suture line 312 .

As shown in FIG. 4 , the first suture line 311 is inserted between the first side of the backing 100 and the repair patch 200 . Multiple sections of double-stranded wire sleeves are exposed on the sheet 200, and a lasso structure is formed between the double-stranded wire sleeves. Multiple sections of single-stranded wires are exposed on the second side of the backing 100, and the second suture line 312 is threaded multiple times. Provided in the noose structure, the noose structure can be untied when the second suture line 312 is pulled. After the locking structure is untied, the first suture line 311 and the second suture line 312 are separated.
具体地，当所述修补片200与所述背衬100处于第一状态时，外力作用拉动所述第二缝合线312的牵引段自由端时，所述第二缝合线312由所述套索结构中脱出，同时，所述第一缝合线311的套索结构解散。所述修补片200与所述背衬100的连接状态由第一状态转换至第二状态，即，使背衬100与修补片200分离。Specifically, when the patch 200 and the backing 100 are in the first state and an external force pulls the free end of the traction section of the second suture 312, the second suture 312 is pulled by the lasso. At the same time, the lasso structure of the first suture line 311 is disbanded. The connection state of the repair patch 200 and the backing 100 is converted from the first state to the second state, that is, the backing 100 and the repair patch 200 are separated.
在一些实施例中，所述牵引线320与所述第二缝合线312连接，在外力作用下拖拽所述牵引线320可以将所述第二缝合线312与所述第一缝合线311分离。如图1所示，所述牵引线320与所述缝合线310连接的至少部分构造为牵引环321，所述牵引环321套设所述第二缝合线312。In some embodiments, the traction line 320 is connected to the second suture line 312, and dragging the traction line 320 under the action of external force can separate the second suture line 312 from the first suture line 311. . As shown in FIG. 1 , at least part of the connection between the traction line 320 and the suture 310 is configured as a traction ring 321 , and the traction ring 321 covers the second suture 312 .
在一些实施例中，所述修补片200与所述背衬100具有至少一部分连接的第一状态，以及所述修补片200与所述背衬100相对独立的第二状态，外力作用拖拽所述牵引线320以将所述修补片200与所述背衬100由第一状态转换至第二状态。In some embodiments, the patch 200 and the backing 100 have a first state in which they are at least partially connected, and a second state in which the patch 200 and the backing 100 are relatively independent. The pulling wire 320 is used to convert the repair patch 200 and the backing 100 from the first state to the second state.
具体地，当所述修补片200与所述背衬100处于第一状态时，所述修补片200与所述背衬100的至少一部分连接，此时吻合口加固修补片200套设于弧形吻合器或至少一部分包裹所述弧形吻合器。Specifically, when the patch 200 and the backing 100 are in the first state, the patch 200 is connected to at least a part of the backing 100. At this time, the anastomosis reinforcing patch 200 is sleeved on the arc. The stapler or at least part of it wraps the arc-shaped stapler.
当所述修补片200与所述背衬100处于第二状态时，所述修补片200与所述背衬100相对独立，吻合口加固修补片200修补至病人患处，背衬100和弧形吻合器可以抽出病人体外。When the patch 200 and the backing 100 are in the second state, the patch 200 and the backing 100 are relatively independent, the anastomotic reinforcement patch 200 is repaired to the patient's affected area, and the backing 100 is consistent with the arc. The device can be withdrawn from the patient's body.
当所述修补片200与所述背衬100处于第一状态时，外力作用下拉动所述牵引线320，可以将所述修补片200与所述背衬100的连接状态由第一状态转换至第二状态。When the patch 200 and the backing 100 are in the first state, the pulling wire 320 is pulled under the action of external force, and the connection state of the patch 200 and the backing 100 can be converted from the first state to the first state. Second state.
在一些实施例中，所述背衬100包括：第一弧形结构110以及第二弧形结构120。In some embodiments, the backing 100 includes a first arc-shaped structure 110 and a second arc-shaped structure 120 .
如图5所示，所述第一弧形结构110在所述背衬100的第一面上朝逆时针方向弯曲；所述第二弧形结构120在所述背衬100的第一面上朝顺时针方向弯曲，其中，所述第一弧形结构110和所述第二弧形结构120在所述背衬100的第一面上配置为对称结构。As shown in FIG. 5 , the first arc-shaped structure 110 is curved in the counterclockwise direction on the first surface of the backing 100 ; the second arc-shaped structure 120 is on the first surface of the backing 100 Bend in the clockwise direction, wherein the first arc-shaped structure 110 and the second arc-shaped structure 120 are configured as a symmetrical structure on the first surface of the backing 100 .
所述第一弧形结构110和所述第二弧形结构120上分别设置有第一修补片210和第二修补片200，所述第一修补片210在所述背衬100的第一面上朝逆时针方向弯曲；所述第二修补片200在所述背衬100的第一面上朝顺时针方向弯曲。所述第一修补片210和所述第二修补片200在所述背衬100的第一面上配置为对称结构。A first patch 210 and a second patch 200 are respectively provided on the first arc-shaped structure 110 and the second arc-shaped structure 120. The first patch 210 is on the first side of the backing 100. The second patch 200 is bent in a clockwise direction on the first surface of the backing 100 . The first patch 210 and the second patch 200 are arranged in a symmetrical structure on the first surface of the backing 100 .
在临床实践中，第一弧形结构110以及第二弧形结构120分别套设于弧形吻合器的两个吻合钳上，当两个吻合钳啮合时，具有第一弧形结构110以及第二弧形结构120的背衬100沿对称轴对折，实现在狭长空间内的弧形吻合口修补作业。In clinical practice, the first arc-shaped structure 110 and the second arc-shaped structure 120 are respectively sleeved on the two stapling forceps of the arc-shaped stapler. When the two stapling forceps are engaged, the first arc-shaped structure 110 and the second arc-shaped structure 120 are formed. The backing 100 of the two arc-shaped structures 120 is folded in half along the symmetry axis to realize the arc-shaped anastomosis repair operation in a narrow space.
在一些实施例中，所述缝合线310为封闭环形，沿着所述第一弧形结构110和所述第二弧形结构120的边缘延伸，所述第一弧形结构110和所述第二弧形结构120的对称轴上横穿两条所述缝合线310。所述牵引线320套设对称轴上的两条所述缝合线310，在外力作用下拖拽所述牵引线320，以使两根所述缝合线310同时与所述背衬100分离。In some embodiments, the suture line 310 is in a closed ring shape and extends along the edges of the first arc-shaped structure 110 and the second arc-shaped structure 120 . The two arc-shaped structures 120 cross the two suture lines 310 on their symmetry axes. The traction line 320 is sleeved on the two suture lines 310 on the axis of symmetry, and the traction line 320 is dragged under the action of external force, so that the two suture lines 310 are separated from the backing 100 at the same time.
在一些实施例中，所述缝合线310可以设置有两组，如图6、图7所示，两组缝合线310分别沿着第一弧形结构110以及第二弧形结构120的边缘延伸，形成两个封闭环形结构。牵引线320套设对称轴两侧的两条所述缝合线310远离所述端帽103的一端，在外力作用下拖拽所述牵引线320，以使两根所述缝合线310同时与所述背衬100分离。In some embodiments, the suture lines 310 may be provided in two groups. As shown in FIGS. 6 and 7 , the two groups of suture lines 310 extend along the edges of the first arc-shaped structure 110 and the second arc-shaped structure 120 respectively. , forming two closed ring structures. The traction line 320 is sleeved on one end of the two suture lines 310 on both sides of the symmetry axis away from the end cap 103, and the traction line 320 is dragged under the action of external force, so that the two suture lines 310 are connected to the end cap 103 at the same time. The backing 100 separates.
由于所述缝合线310为封闭环形，故此，当外力作用下拖拽牵引线320时，两组封闭环形的缝合线310具有相同的力趋性，拉动牵引段即可使背衬100与修补片200由第一状态转换至第二状态。Since the suture line 310 is a closed ring, when the traction line 320 is dragged under the action of external force, the two groups of closed ring suture lines 310 have the same force tendency, and the backing 100 and the repair patch can be separated by pulling the traction section. 200 transitions from the first state to the second state.
需要单独说明的是，拉动牵引线320时，由于牵引环321的设置，两根缝合线310的受到的拉力基本相同。这是因为对于通常在拉动牵引线320时，位于两侧的牵引线320虽然同时被拉动但是各自单独受力，由于位于内外圆弧的牵引线320的长度不同，因而拆解速度也不同，容易造成修补片两侧受力不均。而通过牵引环321的设置，能够使得两侧的牵引线320同时受力，并且修补片200两侧的牵引线320虽然拆解速度不同，但是牵引线320与牵引环321之间是套接，使得拆解快一侧的牵引线320可以补偿给拆解慢的一侧的牵引线320，从而实现牵引线320被同时拉动，且受力均匀。故此，拉动牵引线320带动缝合线310与背衬100分离时，可以保证修补片200与吻合口连接的稳定性，避免由于拆线受力不均而影响修补片200在吻合器上的准确定位。It should be noted separately that when pulling the traction wire 320, due to the arrangement of the traction ring 321, the two suture wires 310 receive substantially the same pulling force. This is because when pulling the traction wire 320, the traction wires 320 on both sides are pulled at the same time but are stressed separately. Since the lengths of the traction wires 320 located in the inner and outer arcs are different, the disassembly speeds are also different, making it easier to This results in uneven stress on both sides of the patch. Through the arrangement of the traction ring 321, the traction wires 320 on both sides can be stressed at the same time, and although the traction wires 320 on both sides of the repair patch 200 are disassembled at different speeds, the traction wires 320 and the traction ring 321 are connected. This allows the traction wire 320 on the faster side to be disassembled to compensate for the traction wire 320 on the slower side, so that the traction wires 320 can be pulled simultaneously and receive even force. Therefore, when pulling the traction wire 320 to separate the suture 310 from the backing 100, the stability of the connection between the patch 200 and the anastomosis can be ensured, and the uneven force on the removal of the sutures from affecting the accurate positioning of the patch 200 on the stapler can be avoided. .
在一些实施例中，所述修补片200上设置有引刀槽。所述引刀槽沿着所述修补片200的长度方向延伸，所述引刀槽大致呈条状，在与水平面平行的平面上的正投影大致呈矩形形状，但是不限于此，在其他示例中，上述正投影还可以为倒角矩形或其他多边形形状。上述仅作为可选示例进行说明，不能理解成对本发明的限制。In some embodiments, the repair piece 200 is provided with a guide groove. The guide groove extends along the length direction of the repair piece 200 . The guide groove is generally in the shape of a strip, and the orthographic projection on a plane parallel to the horizontal plane is generally in a rectangular shape. However, it is not limited to this. In other examples, , the above-mentioned orthographic projection can also be a chamfered rectangle or other polygonal shape. The above are only described as optional examples and should not be construed as limitations of the present invention.
所述引刀槽用于与吻合器的切割组件配合使用，通过所述引刀槽限制所述切割组件在对待处理组织等切割处理时的切割位置。The knife guide groove is used in conjunction with the cutting component of the stapler, and the cutting position of the cutting component during cutting of tissue to be treated is limited by the knife guide groove.
具体地，当所述修补片200与吻合口接触后，所述吻合器内部的切割组件可以沿着所述引刀槽的延伸方向将所述修补片200切割成两部分，引刀槽的设置能够保证切割组件完全切断修补片200，同时能够保证修补片200与吻合口完全吻合，而无需使用额外的切割工具，进而能够实现了实际应用中的操作便利性。Specifically, when the patch 200 comes into contact with the anastomosis, the cutting assembly inside the stapler can cut the patch 200 into two parts along the extending direction of the knife groove. The arrangement of the knife groove It can ensure that the cutting assembly completely cuts off the patch 200 and at the same time ensures that the patch 200 completely matches the anastomosis without using additional cutting tools, thereby achieving operational convenience in practical applications.
