本申请实施例公开的缝合装置，主要应用于内镜手术中对各类型创面、瘘口、穿孔等进行减张和闭合，并特别适用于缝合较大的创面。该缝合装置包括至少两个带线夹子1，在缝合过程中，将带线夹子1分别夹在创面的周围，通过将各带线夹子1向中间牵拉使之聚拢，使创面周围的肌体向中间收紧，实现创面的减张和闭合，从而实现将创面缝合。The suturing device disclosed in the embodiments of the present application is mainly used for reducing and closing various types of wounds, fistulas, perforations, etc. in endoscopic surgery, and is especially suitable for suturing larger wounds. The suturing device comprises at least twoclips 1 with thread. During the suturing process, theclips 1 with thread are respectively clamped around the wound surface. The middle is tightened to reduce and close the wound surface, so as to suture the wound surface.

如图1所示，虚线部分表示为创面，该缝合装置的两个带线夹子1分别夹在创面的两侧，将两个带线夹子1向中间拉紧即可以实现将创面减张和闭合。可以理解的是，术者可根据创面的大小选择不同数量的带线夹子1，对于较小的创面，带线夹子1可以仅设置两个，而对于较大的创面，可以设置多个带线夹子1围绕在创面的周围，以提升缝合的效果。As shown in Figure 1, the dashed part is the wound surface. The twowire clips 1 of the suture device are respectively clamped on both sides of the wound surface, and the wound can be reduced and closed by pulling the twowire clips 1 toward the middle. . It can be understood that the operator can choose different numbers ofclips 1 with wire according to the size of the wound. For smaller wounds, only two clips withwire 1 can be installed, while for larger wounds, multiple wire clips can be installed.Clip 1 surrounds the wound surface to enhance the effect of suture.

具体的，该带线夹子1包括夹子本体2和缝合线3，缝合线3连接于夹子本体2上。在一些实施例中，夹子本体2可以直接选用现有一次性使用组织夹，在现有一次性使用组织夹的基础上连接缝合线3，即可制成一个带线夹子1。缝合线3选用医用柔性材料制作而成，材质可为金属或者高分子，缝合线3和夹子本体2的连接方式可为焊接或者打结的方式，本领域技术人员可根据具体材质选择合适的连接方式将两者连接在一起。由于缝合线3相对于夹子本体2而言较为细小，且材质比较柔软，不会对夹子本体2的移动造成干涉，因而在连接缝合线3之后，夹子本体2仍可顺畅经过内窥镜钳道，顺利完成缝合手术。Specifically, theclip 1 with wire includes aclip body 2 and asuture 3 , and thesuture 3 is connected to theclip body 2 .

Preferably, in some embodiments, thesuture 3 is attached to theclip 6 . During suture, since the body around the wound needs to be clamped by theclip 6, compared with connecting thesuture 3 to theclip base 5, when thesuture 3 is connected to theclip 6, its connection position is far from the wound surface. Closer, after the two clips are closed, the wound can be brought closer and the effect of the suture can be improved. In addition, thesuture thread 3 is connected to theclip 6 so that the root is closer to the wound surface, so that theclip body 2 will not be pulled down, which further ensures the safety of suture.

请一并结合图2所示，该缝合装置还包括释放装置7，释放装置7用于将带线夹子1由钳道送入并释放，使带线夹子1夹在创面周围。一般地，可直接采用现有内窥镜手术中组织夹释放装置，以方便操作者实施手术操作。在缝合过程中，该释放装置7将带线夹子1逐一通过钳道送入体内，并后拉手柄释放带线夹子1，使带线夹子1分别夹在创面的周围，缝合线3被留置在钳道内。操作者将预留在钳道内的所有缝合线3锁紧，剪断多余缝合线3，即完成创面的减张和闭合。2, the suturing device further includes a release device 7, the release device 7 is used for feeding and releasing thewire clip 1 from the forceps, so that thewire clip 1 is clamped around the wound surface. Generally, the existing tissue clip releasing device in endoscopic surgery can be directly used, so as to facilitate the operator to perform the surgical operation. During the suturing process, the release device 7 sends theclips 1 with wire into the body one by one through the forceps channel, and pulls the handle back to release theclips 1 with wire, so that theclips 1 with wire are respectively clamped around the wound surface, and thesuture 3 is left in the inside the clamp. The operator locks all thesutures 3 reserved in the forceps channel, and cuts off theexcess sutures 3, that is, the reduction and closure of the wound are completed.

The distal end of the slidingblock 19 is further provided with an accommodation cavity communicating with the throughhole 22 , and a slot is also opened on the side wall of the accommodation cavity to form thesecond shearing unit 20 . Thefirst shearing unit 18 and thesecond shearing unit 20 constitute the shearingpart 12 , when theslider 19 slides proximally in thebase 17 , the edges of the two slots are staggered to each other, so as to cut thesuture 3 . cut.

在一些实施例中，拉绳13一般可采用0.4mm缆绳，其远端设置一球头，形成阻挡部23。自远端向近端，拉绳13依次穿过第二锁块10的弹性孔道、第一锁块9，进入基座17内从滑块19的容纳腔、贯孔22穿过，接着穿过导管15连接操控机构14。In some embodiments, the pullingrope 13 can generally be a 0.4 mm cable, and a ball head is provided at the distal end to form the blockingpart 23 . From the distal end to the proximal end, thepull rope 13 sequentially passes through the elastic hole of thesecond lock block 10 and thefirst lock block 9, enters thebase 17, passes through the accommodation cavity of theslider 19, the throughhole 22, and then passes through Theconduit 15 is connected to thesteering mechanism 14 .

如图8所示，该锁紧装置4在初始状态下，第一锁块9和第二锁块10之间的锁紧区域应当具备一定的穿线空间，此时，第一锁块9和第二锁块10是分离的，第二锁块10通过拉绳13保持与锁紧装置4其余部分的连动。基座17和滑块19的远端边缘齐平，两个狭槽相互对齐，并与容纳腔共同形成穿线通道。第一锁块9插入设置在滑块19的容纳腔中，其限位部21抵靠于基座17的边缘，限位部21的外径与基座17的外径大致相同。操作者需要将预留在钳道内的缝合线3穿过锁紧区域缝，并从穿线通道的两个狭槽穿出。然后将锁紧装置4的远端沿着缝合线3逐渐插入钳道，到达创面附近,拉紧缝合线，并将锁紧元件8向缝合线3的根部靠拢。As shown in FIG. 8, in the initial state of thelocking device 4, the locking area between thefirst lock block 9 and thesecond lock block 10 should have a certain threading space. The two locking blocks 10 are separated, and thesecond locking block 10 is kept in linkage with the rest of thelocking device 4 through the pullingrope 13 . The distal edges of thebase 17 and theslider 19 are flush with each other, and the two slots are aligned with each other, and together with the accommodating cavity form a threading channel. Thefirst locking block 9 is inserted into the accommodating cavity of theslider 19 , and its limitingportion 21 abuts against the edge of thebase 17 , and the outer diameter of the limitingportion 21 is approximately the same as that of thebase 17 . The operator needs to pass thesuture 3 reserved in the forceps channel through the locking area slit and out from the two slots of the threading channel. Then, the distal end of thelocking device 4 is gradually inserted into the forceps channel along thesuture 3 to reach the vicinity of the wound surface, the suture is tightened, and thelocking element 8 is brought closer to the root of thesuture 3 .

如图9所示，操作者通过操控机构14将拉绳13向近端牵拉，第二锁块10随即被拉入第一锁块9中，两者之间的缝合线3锁定收紧。As shown in FIG. 9 , the operator pulls thepull rope 13 toward the proximal end through themanipulation mechanism 14 , thesecond lock block 10 is then pulled into thefirst lock block 9 , and thesuture line 3 between the two is locked and tightened.

如图10所示，在锁紧状态下，继续向近端牵拉拉绳13，其球头形成的阻挡部23对第二锁块10施加指向近端的力，同时由于限位部21的存在，基座17形成反力架施加反向力，两个力的共同作用使弹性孔道变形，阻挡部23从弹性孔道脱出，解除对拉绳13的锁止，使拉绳13与第二锁块10分离。随着拉绳13向近端滑动，其阻挡部23抵靠于滑块19的贯孔22远端边缘，从而滑块19被拉绳13拉动沿着基座17向近端滑动，第一剪切单元18和第二剪切单元20交错剪切多余的缝合线3。As shown in FIG. 10 , in the locked state, continue to pull thepull rope 13 toward the proximal end, and the blockingportion 23 formed by the ball head exerts a force directed toward the proximal end to thesecond locking block 10 . Existing, the base 17 forms a reaction force frame and exerts a reverse force, the combined action of the two forces deforms the elastic channel, the blockingportion 23 comes out of the elastic channel, releases the locking of thepull rope 13, and makes thepull rope 13 and thesecond lock Block 10 separates. As thepull rope 13 slides toward the proximal end, its blockingportion 23 abuts against the distal edge of the throughhole 22 of theslider 19, so that theslider 19 is pulled by thepull rope 13 and slides toward the proximal end along thebase 17. The cuttingunit 18 and thesecond cutting unit 20 cut theredundant sutures 3 alternately.

如图11所示，随着滑块19继续向近端移动，第一锁块9也从容纳腔逐渐脱出，与支持部16完全分离。此时，可抽离操控组件11，锁紧元件8留于体内。As shown in FIG. 11 , as the slidingblock 19 continues to move toward the proximal end, thefirst locking block 9 also gradually comes out of the accommodating cavity and is completely separated from the supportingportion 16 . At this time, thecontrol assembly 11 can be pulled out, and thelocking element 8 remains in the body.

与以上实施例有所不同，在另外一些实施例中，第一锁块9插入设置于基座17中，其插入部分与基座17内壁贴合。滑块19仅用于和基座17配合形成剪切部12，因而以图8的结构为基础做出改变，滑块19应设置的更短，缩短的主要是以上实施例中容纳腔用于插入设置第一锁块9的部分。具体的锁紧、切割操作与以上实施例大致相同。Different from the above embodiments, in other embodiments, thefirst locking block 9 is inserted into thebase 17 , and the inserted part thereof is in contact with the inner wall of thebase 17 . The slidingblock 19 is only used to cooperate with the base 17 to form theshearing portion 12. Therefore, changes are made based on the structure of FIG. 8. The slidingblock 19 should be set shorter. Insert the part where thefirst lock block 9 is provided. The specific locking and cutting operations are substantially the same as the above embodiments.

此外，在其他的一些实施例中，支持部16取消了滑块19的设置，仅设置基座17。基座17大致呈圆筒形，连接于导管15的远端，其侧壁上开设有一个狭槽，狭槽的边缘具有锋利的刀刃，形成剪切部12，该狭槽与基座17的内腔形成缝合线3的穿线通道。拉绳13从基座17的内腔穿过，经过第一锁块9后与第二锁块10连接。第一锁块9插入设置于基座17中，其插入部分与基座17内壁贴合，其限位部21抵靠于基座17的边缘，限位部21的外径与基座17的外径大致相同。In addition, in some other embodiments, thesupport part 16 cancels the provision of theslider 19, and only thebase 17 is provided. Thebase 17 is substantially cylindrical and is connected to the distal end of thecatheter 15. A slot is formed on the side wall of thebase 17. The edge of the slot has a sharp edge to form ashearing portion 12. The lumen forms a threading channel for thesuture 3 . Thepull cord 13 passes through the inner cavity of thebase 17 , passes through thefirst lock block 9 and is connected to thesecond lock block 10 . Thefirst locking block 9 is inserted into thebase 17 , and its insertion part is in contact with the inner wall of thebase 17 . The outer diameter is approximately the same.

在该实施例中，操作者仍旧通过操作操控机构14，控制拉绳13向近端拉紧，将第二锁块10拉入第一锁块9中，实现缝合线3的锁定收紧。此时继续拉紧缝合线3，通过将锁紧装置4的操控组件11向体外抽出，基座17够实现与锁紧元件8的分离，将其留于体内，同时其剪切部12可将多余缝合线3割断。In this embodiment, the operator still operates thecontrol mechanism 14 to control thepull rope 13 to be pulled proximally and pull thesecond locking block 10 into thefirst locking block 9 to achieve locking and tightening of thesuture 3 . At this time, continue to tighten thesuture 3. By pulling out thecontrol assembly 11 of thelocking device 4 to the outside of the body, thebase 17 can be separated from the lockingelement 8, and it can be kept in the body. Cut offexcess suture 3.
