[0002] Surgery, also known as surgery or incision, refers to the process of inserting surgical equipment or instruments into the human body or other biological tissues through the operation of a surgeon or other professionals, in order to remove lesions, change structures, or implant foreign objects by external force. In surgery, hemostatic forceps are usually used to stop bleeding, and sutures are used to close the wound.

[0003] When using multiple hemostatic forceps, medical staff need to tighten multiple hemostatics together. One end of the suture can be knotted and fixed on the hemostatic forceps. However, due to the limited operating space, it is inconvenient for medical staff to knot and cut the other end of the suture. Therefore, a special integrated device for locking and cutting the suture is needed. Utility Model Content

[0004] The purpose of this invention is to provide an integrated suture locking and cutting device to solve the problem mentioned in the background art, where it is inconvenient for medical staff to tie and cut one end of the suture during surgery due to the limited operating space.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suture locking and cutting integrated device, comprising a rubber sleeve and a fixing mechanism. One end of the rubber sleeve is provided with a locking head, and the bottom end of the rubber sleeve is provided with a spring sleeve. A first pull plate is slidably connected to the upper middle part of the spring sleeve, and a second pull plate is slidably connected to the middle part of the spring sleeve. A first spring is fixedly connected to the top end of the second pull plate, and the top end of the first spring is fixedly connected to the bottom end of the first pull plate. A sliding hole is provided at the bottom end of the spring sleeve, and a pull rod is slidably connected inside the sliding hole. The top end of the pull rod is fixedly connected to the second pull plate, and a pull ring is fixedly connected to the bottom end of the pull rod. Two sets of thread holes are provided at the top end of the spring sleeve.

[0006] Preferably, the fixing mechanism includes an insertion hole, a third pull plate, a cutter, a steel wire rope, a fixing rod, a circular groove, an elastic rod, and a suture body. The bottom end of the locking head has an insertion hole, the bottom end of the locking head has a third pull plate, the bottom end of the cutter is fixedly connected to a cutter, both ends of the third pull plate are fixedly connected to steel wire ropes, and the steel wire ropes pass through the thread hole and are fixedly connected to the first pull plate. The insertion hole has a fixing rod inside, and the bottom end of the fixing rod is fixedly connected to the third pull plate. The upper middle part of the fixing rod has a circular groove. The insertion hole has symmetrically fixedly connected elastic rods, and the middle part of each elastic rod is located inside the circular groove. The rubber sleeve has a suture body inside, which facilitates cutting the suture body.

[0007] Preferably, the locking head is inverted conical, and the rubber sleeve is elastic, which facilitates locking the main body of the suture.

[0008] Preferably, a buffer pad is fixedly connected to the top of the spring sleeve, and the steel wire rope passes through the buffer pad to facilitate buffering of the cutter.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When using this device, the suture body is first passed through the rubber sleeve, placing it between the rubber sleeve and the locking head. Simultaneously, the suture body is positioned between two sets of steel wire ropes. A pull rod and pull ring facilitate the pulling of the second pull plate by medical staff. The second pull plate, first spring, first pull plate, steel wire rope, third pull plate, fixing rod, and elastic rod pull the locking head inwards from the rubber sleeve, thus fixing the suture body between the rubber sleeve and the locking head. This allows medical staff to tighten and secure the suture body. When the rebound force of the first spring exceeds the elastic force of the elastic rod, the third pull plate and cutter detach. The first spring, first pull plate, and steel wire rope enable the third pull plate and cutter to move rapidly towards the spring sleeve, causing the cutter to move quickly. When the cutter impacts the buffer pad, it cuts the suture body, facilitating the cutting work by medical staff. This device can complete locking and cutting operations in a confined space, making it easier for medical staff to lock and cut sutures, thereby reducing surgical difficulty and increasing the success rate.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 One embodiment provided by this utility model:

[0020] The suture locking and cutting integrated device includes a rubber sleeve 1 and a fixing mechanism. One end of the rubber sleeve 1 is provided with a locking head 2, and the bottom end of the rubber sleeve 1 is provided with a spring sleeve 3. The upper middle part of the spring sleeve 3 is slidably connected to a first pull plate 6, and the middle part of the spring sleeve 3 is slidably connected to a second pull plate 7. The top end of the second pull plate 7 is fixedly connected to a first spring 8, and the top end of the first spring 8 is fixedly connected to the bottom end of the first pull plate 6. The bottom end of the spring sleeve 3 is provided with a sliding hole 4, and a pull rod 10 is slidably connected inside the sliding hole 4. The top end of the pull rod 10 is fixedly connected to the second pull plate 7, and the bottom end of the pull rod 10 is fixedly connected to a pull ring 11. The top end of the spring sleeve 3 is provided with two sets of thread holes 9 to facilitate the fixing of a third pull plate 13 and a cutter 14.

[0021] Furthermore, the fixing mechanism includes an insertion hole 12, a third pull plate 13, a cutter 14, a steel wire rope 15, a fixing rod 16, a circular groove 17, an elastic rod 18, and a suture body 19. The bottom end of the locking head 2 has an insertion hole 12, and the bottom end of the locking head 2 is provided with a third pull plate 13. The bottom end of the cutter 14 is fixedly connected to a cutter 14. Both ends of the third pull plate 13 are fixedly connected to steel wire ropes 15, which pass through the thread holes 9 and are fixedly connected to the first pull plate 6. The insertion hole 12 contains a fixing rod 16, and the bottom end of the fixing rod 16 is fixedly connected to the third pull plate 13. The upper middle part of the fixing rod 16 has a circular groove 17. The insertion hole 12 contains symmetrically fixed elastic rods 18, and the middle parts of the elastic rods 18 are all located inside the circular grooves 17. The rubber sleeve 1 contains a suture body 19. The first spring 8 pulls the steel wire rope 15 through the first pull plate 6. The elastic rod 18 is pulled by the third pull plate 13 and the fixing rod 16. At this time, the elastic rod 18 deforms and can pull the locking head 2 to move into the rubber sleeve 1. The locking head 2 can cause the rubber sleeve 1 to deform. At this time, the suture body 19 can be fixed between the rubber sleeve 1 and the locking head 2, so that the medical staff can tighten and fix the suture body 19. When the rebound force of the first spring 8 exceeds the elastic force of the elastic rod 18, the third pull plate 13 and the cutter 14 will fall off. At this time, the first pull plate 6 and the steel wire rope 15 can be pulled by the rebound force of the first spring 8. Thus, the first spring 8, the first pull plate 6 and the steel wire rope 15 can move quickly towards the spring sleeve 3, so that the cutter 14 moves quickly. When the cutter 14 hits the buffer pad 5, the suture body 19 can be cut, thus facilitating the cutting work of the medical staff.

[0022] It should be noted that the locking head 2 is inverted conical, the rubber sleeve 1 is elastic, which facilitates locking the suture body 19, the top of the spring sleeve 3 is fixedly connected to the buffer pad 5, the steel wire rope 15 passes through the buffer pad 5, which facilitates the buffering of the cutter 14, the suture body 19 is located between the rubber sleeve 1 and the locking head 2, and the middle part of the suture body 19 is located between the two sets of steel wire ropes 15, which facilitates cutting the suture body 19. The buffer pad 5 is elastic, which improves the buffering performance. The first pull plate 6 and the second pull plate 7 are the same size, and the outer diameter of the first pull plate 6 and the second pull plate 7 is adapted to the inner diameter of the spring sleeve 3, which facilitates the sliding of the first pull plate 6 and the second pull plate 7 inside the spring sleeve 3.

[0023] Working principle: When medical staff use this device, they first pass the suture body 19 through the rubber sleeve 1, so that the suture body 19 is between the rubber sleeve 1 and the locking head 2, and also between the two sets of steel wire ropes 15. After tightening the suture body 19, they hold the spring sleeve 3 with one hand and pull the pull ring 11 with the other. The pull ring 11 pulls the second pull plate 7 through the pull rod 10, and the second pull plate 7 pulls the first spring 8. At this time, the first spring 8 is stretched. The first spring 8 pulls the steel wire rope 15 through the first pull plate 6. The steel wire rope 15 pulls the elastic rod 18 through the third pull plate 13 and the fixing rod 16. At this time, the elastic rod 18 deforms, and at the same time, the elastic rod 18 can pull the locking head 2 to move inward into the rubber sleeve 1. The locking head 2 can cause the rubber sleeve 1 to deform, and at this time, the suture body can be tightened. The suture body 19 is fixed between the rubber sleeve 1 and the locking head 2, making it convenient for medical staff to tighten and fix the suture body 19. When the rebound force of the first spring 8 exceeds the elastic force of the elastic rod 18, the third pull plate 13 and the cutter 14 fall off. At this time, under the action of the rebound force of the first spring 8 itself, the first pull plate 6 and the steel wire rope 15 can be pulled to move. Thus, the first spring 8, the first pull plate 6 and the steel wire rope 15 can move quickly towards the spring sleeve 3, thereby making the cutter 14 move quickly. When the cutter 14 hits the buffer pad 5, the suture body 19 can be cut, thus facilitating the cutting work of medical staff. This device can complete the locking and cutting work in a narrow space, thus facilitating the operation of locking and cutting sutures by medical staff, thereby reducing the difficulty of surgery and improving the success rate of surgery.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
