The interlink clip suturing device disclosed by the embodiment of the application is mainly applied to the relaxation and closure of various wound surfaces, fistula, perforation and the like in endoscopic surgery, and is particularly suitable for suturing large wound surfaces.

The interlinked clip sewing device comprises a belt line clip 1 and a belt clip 2. As shown in fig. 1, the dotted line part indicates a wound surface, in the suturing process, the band clamp 1 and the band clamp 2 are respectively clamped around the wound surface, the suture line 3 of the band clamp 1 passes through the ring of the band clamp 2, the band clamp 1 and the band clamp 2 are drawn towards the middle by drawing the suture line 3, and the body around the wound surface is drawn towards the middle, so that the wound surface can be quickly and efficiently sutured.

It can be understood that the number of the band clamp 2 is determined according to the size of the wound surface, and for a smaller wound surface, only one band clamp 2 can be arranged and clamped on two sides of the wound surface together with the band clamp 1, so that the wound surface can be closed in a tension reducing manner; and to great surface of a wound, can set up a plurality of belt ring clips 2, arrange around the surface of a wound with belt line clip 1 in proper order, each ring of belt ring clip 2 is passed in proper order to the stylolite 3 of belt line clip 1, through tractive stylolite 3, carries out the tractive of a plurality of angles to the surface of a wound to promote sutural effect.

Specifically, referring to fig. 2, the suture clip 1 includes a clip body 25 and a suture 3, the suture 3 includes a connecting end and a pulling end, and the connecting end of the suture 3 is connected to the clip body 25. In some embodiments, the clip body 25 can be directly selected from the existing disposable tissue clip, and the suture 3 is connected on the basis of the existing disposable tissue clip, so that the clip with the thread 1 can be manufactured. The suture 3 is made of a medical flexible material, the material can be metal or high polymer, the connection mode of the suture 3 and the clamp body 25 can be a welding or knotting mode, and a person skilled in the art can select a proper connection mode according to the specific material to connect the suture 3 and the clamp body together. Because the suture line 3 is relatively thin and soft relative to the clip body 25, the movement of the clip body 25 is not interfered, and the clip body 25 can still smoothly pass through the endoscopic forceps channel after the suture line 3 is connected, thereby smoothly finishing the suture operation.

Referring also to fig. 3, the band clamp 2 includes a clamp body 25 and a ring 26, the ring 26 being connected to the clamp body 25. In some embodiments, the clip body 25 can be directly selected from the existing disposable tissue clip, and the existing disposable tissue clip is modified to be connected with the ring 26 to form the ring-shaped clip 2. Correspondingly, the ring 26 is made of a medical flexible material, the material of the ring can be metal or high polymer, the connection mode of the ring 26 and the clamp body 25 can be welding or a mode of tying a ring by knotting, and a person skilled in the art can select a proper connection mode according to the specific material to connect the ring and the clamp together. This application is connected on clip body 25 and is set up a ring 26, and does not select to punch on clip body 25, because the size of clip body 25 itself is very little, punches and has increased the preparation degree of difficulty on it, and the hole of punching also is not convenient for wear to establish stylolite 3. And relatively, set up a ring 26 in addition on the clip body 25, more convenient pass suture line 3 to because ring 26 is flexible, softer, be difficult for the fish tail pincers way, be difficult for cutting off suture line 3, also can not cause the interference to the removal of clip body 25, therefore belt loop clip 2 also can smoothly pass through the endoscope pincers way, accomplishes the suture operation smoothly.

Referring again to fig. 1, the clip body 25 includes a holder 5 and a clip 6, the clip 6 is connected to the holder 5, and the suture 3 can be connected to either the holder 5 or the clip 6. Preferably, in some embodiments, the attached ends of suture 3 are attached to clip 6.

Correspondingly, the ring 26 can be connected to the holder 5 and also connected to the clip 6, preferably, in some embodiments, the ring 26 is connected to the clip 6, since the diameter of the clip 6 is smaller than that of the holder 5, the ring 26 is connected to the clip 6, the overall outer diameter of the clip body 25 is not increased, and after the clip bodies 25 are folded, the wound can be closer, and the clip body 25 can be prevented from falling.

As shown in fig. 2 and 3, the interlinked clip suturing device further includes a releasing device 7, and the releasing device 7 is used for feeding and releasing the band wire clamp 1 or the band clamp 2 from the channel, so that the clamp body 25 is clamped around the wound surface. Generally, the tissue clip releasing device in the existing endoscopic surgery can be directly adopted to facilitate the operator to perform the surgical operation. In the suturing process, the releasing device 7 sends the band-thread clamp 1 into a body through a forceps channel, the handle is pulled backwards to release the band-thread clamp 1, the band-thread clamp 1 is clamped on one side of a wound surface, the suture thread 3 is kept in the forceps channel, the ring 26 with the band-thread clamp 2 is sleeved into the suture thread 3 through the releasing device 7, the band-thread clamp is sequentially sent into the body through the forceps channel and clamped around the wound surface, then an operator pulls and locks the suture thread 3 reserved in the forceps channel, and the redundant suture thread 3 is cut off, namely the tension and the closure of the wound surface are completed.

In some embodiments, the interlinked crimping devices also include a locking device 4, and the locking device 4 locks the trailing end of the suture 3, it being understood that in the locked position, the trailing end of the suture 3 is in the locked position by the locking device 4.

The locking means 4 may employ means for tightening the wire known in the art, such as a rubber ring, a locking block, or the like. The application makes the operation of locking the suture line under the endoscope simpler and safer, and the locking effect is more stable and firmer, and the locking device 4 is specially designed. Referring to fig. 4-14, in some embodiments, the locking device 4 includes a locking element 8, and the locking element 8 mainly includes two parts, namely a first locking piece 9 and a second locking piece 10. The suture 3 passes through the locking area between the first locking piece 9 and the second locking piece 10, and the suture 3 is locked and tightened through the combination of the two.

In some embodiments, locking device 4 further comprises a steering assembly 11 having a threading channel for passing suture 3, the threading channel having a cutting portion 12 for cutting suture 3. And the distal end of the steering assembly 11 is detachably connected to the first locking piece 9 for feeding the locking element 8 into the body to lock the suture 3 and then separating it therefrom. In some embodiments, steering assembly 11 includes steering mechanism 14, catheter 15, and support 16. The actuation mechanism 14 is used to actuate the action of the entire locking device 4, including advancing the distal end of the locking device 4 into the body through the jaw passage along the suture 3, locking the suture 3 by the locking element 8, severing the suture 3, and removing the remainder of the locking device 4 separately from the locking element 8. The guide tube 15 connects the actuating mechanism 14 and the support 16, which on the one hand serves as an extension guide and on the other hand also accommodates the pull cord 13 therein for protection. The holding portion 16 is connected to the distal end of the catheter 15, and the threading passage is formed in the holding portion 16, and functions mainly include three parts, one for smoothly feeding the locking member 8 into the body and maintaining a desired operation state, the other for cutting the unnecessary suture thread 3, and the other for separating from the locking member 8 after the locking of the suture thread 3 is completed.

Locking device 4 further comprises a pull cord 13, the function of pull cord 13 comprising at least the triggering of the locking action of locking element 8 to lock the tightening suture 3. After the locking is completed, the pull cord 13 should also be detached from the locking element 8, leaving the locking element 8 in the body. Therefore, the proximal end of the locking device is connected with the control mechanism 14, so that the pulling control of the pull rope 13 can be carried out through the control mechanism 14, and the distal end of the locking device is detachably connected with the second locking block 10, so that the second locking block 10 can be pulled to the first locking block 9 to lock the suture 3, and the locking device is separated from the second locking block 10 after the locking.

In some embodiments, the first lock 9 is a sleeve as shown in fig. 6, and a stopper 21 is protruded from a distal end of the sleeve in a radial direction. The second lock 10 is a plunger as shown in fig. 7, matching the shape of the sleeve of the first lock 9, inserted into the sleeve to lock the suture 3. Both are made of medical materials, wherein the first locking piece 9 can be made of medical metal materials in an integrated mode, and the second locking piece 10 can be made of medical plastics, and due to certain elasticity, the connecting portion 24 arranged on the first locking piece and used for connecting the pull rope 13 can deform when being pulled and stressed, so that the pull rope 13 is separated from the second locking piece 10. Specifically, the connecting portion 24 is an elastic hole in which the pulling rope 13 can be locked.

In some embodiments, steering mechanism 14 may be implemented using the handle of an existing endoscopic surgical tissue clip release device to facilitate the surgical procedure performed by the operator.

In some embodiments, the conduit 15 may be a spring conduit as shown in fig. 14, which surrounds the pull cord 13 and may be covered by a protective film. In some embodiments, the conduit 15 may also be made of a rubber conduit, or other material.

In some embodiments, the support portion 16 comprises two main parts, namely a base 17 and a slider 19, which are both made of a medical metal material. As shown in fig. 13, the base 17 is substantially cylindrical and is connected to the distal end of the catheter 15, and has a slot cut in its side wall to form a first shearing module 18. The slider 19 is a cylindrical structure with an outer wall attached to an inner wall of the base 17, and has a through hole 22 at the center thereof, the through hole 22 has a slightly larger aperture than the diameter of the pull cord 13, and the pull cord 13 passes through the through hole 22. The distal end of the slider 19 is further provided with a receiving cavity communicated with the through hole 22, and a slot is also formed on the side wall of the receiving cavity to form a second cutting unit 20. The first and second cutting elements 18, 20 constitute the cutting portion 12, the edges of the two slots being staggered with respect to each other to cut the suture 3 when the slider 19 is slid proximally in the base 17.

In some embodiments, pull cord 13 may be a 0.4mm cable having a ball at its distal end forming stop 23. From the far end to the near end, the pulling rope 13 sequentially passes through the elastic hole of the second locking block 10 and the first locking block 9, enters the base 17, passes through the accommodating cavity of the sliding block 19 and the through hole 22, and then passes through the conduit 15 to be connected with the control mechanism 14.

As shown in fig. 9, in the initial state of the locking device 4, the locking area between the first locking piece 9 and the second locking piece 10 should have a certain threading space, and at this time, the first locking piece 9 and the second locking piece 10 are separated, and the second locking piece 10 is kept linked with the rest of the locking device 4 through the pulling rope 13. The distal edges of the base 17 and the slider 19 are flush and the two slots are aligned with each other and form a threading channel together with the receiving cavity. The first lock 9 is inserted into the receiving cavity of the slide 19, the limiting part 21 of the first lock abuts against the edge of the base 17, and the outer diameter of the limiting part 21 is substantially the same as that of the base 17. The operator needs to thread the suture 3, which is reserved in the jaw path, through the locking area seam and out of the two slots of the threading channel. The distal end of the locking device 4 is then gradually inserted into the jaw path along the suture 3, to the vicinity of the wound bed, tightening the suture and bringing the locking element 8 towards the root of the suture 3.

As shown in fig. 10, the operator pulls the pulling rope 13 proximally by the operating mechanism 14, and the second lock block 10 is then pulled into the first lock block 9, and the suture 3 between the two is locked and tightened.

As shown in fig. 11, in the locked state, the pulling rope 13 is continuously pulled to the proximal end, the blocking portion 23 formed by the ball head applies a force pointing to the proximal end to the second lock piece 10, meanwhile, due to the existence of the limiting portion 21, the base 17 forms a counter-force frame to apply a reverse force, the elastic hole channel is deformed under the combined action of the two forces, the blocking portion 23 is disengaged from the elastic hole channel, the locking of the pulling rope 13 is released, and the pulling rope 13 is separated from the second lock piece 10. As the pulling rope 13 slides proximally, the blocking portion 23 abuts against the distal edge of the through hole 22 of the slider 19, so that the slider 19 is pulled by the pulling rope 13 to slide proximally along the base 17, and the first cutting unit 18 and the second cutting unit 20 alternately cut the excess suture thread 3.

As the slider 19 continues to move proximally, the first lock 9 also gradually disengages from the receiving cavity and becomes fully disengaged from the support 16, as shown in FIG. 12. At this point, the operating assembly 11 can be withdrawn, leaving the locking element 8 in the body.

Unlike the previous embodiments, in other embodiments, the first locking piece 9 is inserted into the base 17, and the inserted portion of the first locking piece is attached to the inner wall of the base 17. The slider 19 is only used to form the cutout 12 in cooperation with the base 17, and thus, with a modification based on the structure of fig. 9, the slider 19 should be provided shorter, shortened mainly by the receiving cavity for inserting the portion where the first lock piece 9 is provided in the above embodiment. The specific locking, cutting operation is substantially the same as in the previous embodiment.

In addition, in other embodiments, the support portion 16 eliminates the slider 19 and only the base 17 is provided. Base 17 is generally cylindrical and is attached to the distal end of catheter 15 and has a slot in its side wall with sharp cutting edges forming cutting portion 12, which forms a passage for suture 3 with the lumen of base 17. The pull rope 13 passes through the inner cavity of the base 17, passes through the first locking block 9 and then is connected with the second locking block 10. The first locking piece 9 is inserted into the base 17, the inserted portion of the first locking piece is attached to the inner wall of the base 17, the limiting portion 21 of the first locking piece abuts against the edge of the base 17, and the outer diameter of the limiting portion 21 is substantially the same as that of the base 17.

In this embodiment, the operator, still by operating the operating mechanism 14, controls the proximal tightening of the pull cord 13, pulling the second lock 10 into the first lock 9, and effecting a locked tightening of the suture 3. At this point, the tensioning of the suture 3 is continued, and by withdrawing the operating assembly 11 of the locking device 4 towards the outside of the body, the seat 17 is sufficiently detached from the locking element 8 to leave it inside the body, while its cutting portion 12 can cut off the excess suture 3.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.

The above detailed description is provided for the interlinking and stitching device provided by the embodiment of the present invention, wherein a specific example is applied to explain the principle and the implementation mode of the present invention, and the description of the above embodiment is only used to help understand the technical scheme and the core idea of the present invention; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present invention in its various embodiments.
