The introduction of continuous clamping technology has made it possible to reduce the operation time, but due to the limitations of polymer materials, it is difficult for existing tissue clamps to automatically rebound to their natural state after semi-closing. When clamping continuously, the plastic deformation of the root of the tissue clamp often leads to problems such as clip drop and clamp jam, which ultimately affects the surgical efficiency and experience of clinicians, and has a huge impact on the promotion of continuous clamping technology.

[0051] The following is combined with Figure 2-14 This application is described in further detail.

[0054] Reference Figure 2 In the natural state, the protrusion 212 is against the opening of the concave shaft groove 221, and the first clamp body 21 and the second clamp body 22 are in a small opening state, which is convenient for pre-storing the tissue clip in the tissue clip storage slot 33 of the continuous clip applier;

[0055] Reference Figure 3 In the working state, the protrusion 212 is stuck in the locking groove 222, and the first clamp body 21 and the second clamp body 22 are in a wide open state, which is convenient for clamping, so as to simplify the structure of the clamping forceps.

[0056] Reference Figure 2 A slot 213 is provided on the head of the first clamp body 21, and a clip 223 is provided on the head of the second clamp body 22. The head of the first clamp body 21 is slidably engaged with the head of the second clamp body 22. Positioning protrusions 23 for cooperating with the clamping forceps are fixed on the heads of the first clamp body 21 and the second clamp body 22. An anti-slip protrusion 214 is provided on the inner side surface of the first clamp body 21, and an anti-slip protrusion 224 is provided on the side surface of the second clamp body 22 corresponding to the anti-slip protrusion 214. The anti-slip protrusion 214 and the anti-slip protrusion 224 form a bite structure to prevent tissue from slipping.

[0057] The present application adopts a brand-new structural solution, which overcomes the problems of traditional polymer tissue clips often falling off and getting stuck due to the plastic deformation of the root of the tissue clip when clamping continuously. It can withstand the pressure in the tube of 50KPa for 48 hours without the lock being disengaged or broken; it can meet the technical requirements of continuous clamping for more than 3 times and the strength reduction after clamping not exceeding 5%, and is particularly suitable for clamping forceps for continuously clamping polymer tissue clips.

[0058] The implementation principle of a tissue clip in the embodiment of the present application is:

[0059] Under the action of external force, the first clamp body 21 and the second clamp body 22 can rotate relative to each other. When the head of the first clamp body 21 is engaged with the head of the second clamp body 22, a clamping space is formed. The first clamp body 21 and the second clamp body 22 can rotate around the cylindrical surface of the rotation axis 211.

[0060] Embodiment 1 of the present application also discloses a continuous-fire clip applier capable of continuously firing and applying the above-mentioned tissue clips.

[0061] Reference Figure 4-7 , including a clamp tube 3 and a handle 4 connected to the clamp tube 3, a transmission assembly extending into the clamp tube 3 for launching tissue clips, and a trigger 5 linked to the transmission assembly are installed in the handle 4, a release head 6 is arranged at one end of the clamp tube 3 away from the handle 4, the transmission assembly includes a driving tube 31, a tail tube 32 and a tissue clip storage groove 33, the clamp tube 3 is fixed on the driving tube 31, the tail tube 32 is linked to the trigger 5, the driving tube 31 is pushed by the tail tube 32, a displacement groove 311 is opened on the side wall of the driving tube 31 close to the tail tube 32, a transmission convex head 321 is fixed on the side wall of the tail tube 32, the transmission convex head 321 is correspondingly arranged in the displacement groove 311, and the tissue clip storage groove 33 is arranged in the driving tube 31;

[0062] Reference Figure 8 and Fig. 9 The tissue clip storage groove 33 includes an upper movable groove 331 and a lower storage groove 332 arranged along the length direction of the clamp tube 3. The upper movable groove 331 is embedded in the lower storage groove 332 and slides along the lower storage groove 332. The lower storage groove 332 is fixed on the handle 4. One end of the upper movable groove 331 is fixed on the tail tube 32. The inner wall of the upper movable groove 331 is evenly distributed along the length direction. The elastic push piece 3311 is pressed against the tissue clip. At the two positioning protrusions 23 on the clip, a plurality of elastic stop pieces 3321 are evenly distributed along the length direction of the inner wall of the lower storage slot 332, and the elastic stop pieces 3321 are against the hinge point of the tissue clip. The lower storage slot 332 can clamp no less than 20 tissue clips at one time, and the elastic push piece 3311 and the elastic stop piece 3321 both extend toward the release head 6, and the end of the upper movable slot 331 has a push head for pushing the tissue clip into the release head 6;

[0063] When the upper movable groove 331 is pushed forward, the elastic push piece 3311 abuts against the two positioning protrusions 23 of the tissue clip and pushes the tissue clip at the corresponding position to move toward the release head 6, and because the elastic stop piece 3321 in the lower storage groove 332 is arranged along the direction of movement of the tissue clip, the elastic stop piece 3321 is forced to close;

[0064] When the upper movable groove 331 is reset, the elastic push piece 3311 is forced to close, and the elastic stop piece 3321 in the lower storage groove 332 abuts against the hinge point of the tissue clip to limit the tissue clip;

[0065] Reference Figure 6 and Figure 7 The driving tube 31 and the upper movable groove 331 are respectively provided with guide grooves, and a guide rod 7 is matched in the guide groove. The guide rod 7 is fixed in the handle 4, and a through hole is provided at the end of the lower storage groove 332 near the tail tube 32. The guide rod 7 is inserted in the through hole to fix the lower storage groove 332 on the handle 4. A return spring is provided inside the tail tube 32, and one end of the return spring is against the driving tube 31. At the same time, in order to improve the resetting effect of the clamp, a return spring is also sleeved on the surface of the driving tube 31.

[0066] Reference Figure 4-12 The release head 6 includes a pair of release splints 61, which are hinged on the lower storage slot 332. Each release splint 61 is provided with a guide slot for moving the tissue clip, and a baffle 611 is provided on the side of the guide slot. The end of the guide slot has a retaining slot for matching one of the positioning protrusions 23 on the tissue clip. The guide slot can limit the tissue clip to prevent the tissue clip from falling.

The sliding sleeve 62 is arranged on the surface of the pair of release clamps 61. One end of the sliding sleeve 62 abuts against the end surface of the clamp tube 3. The sliding sleeve 62 is pushed by the clamp tube 3 and the driving tube 31. When the clamp tube 3 and the driving tube 31 push the sliding sleeve 62 forward, the pair of release clamps 61 move toward the middle under the extrusion force and complete the clamping action. After the tissue clamp is closed, the clamping force is ≥1.5Bar;

[0068] The reset piece 63 is fixed on the lower storage groove 332. The reset piece 63 drives a pair of release clamps 61 to open. After clamping is completed, the trigger 5 is reset, and the reset piece 63 restores its deformation to push the pair of release clamps 61 to open, and pushes the sliding sleeve 62 to reset for the next clamping.

[0069] Reference Fig.11 Supporting springs 8 are provided on both upper and lower sides of the lower storage slot 332 near one end of the release head 6.

[0070] The provision of the supporting spring piece 8 can limit and support the tissue clamp up and down, making it easier for the tissue clamp to enter the release clamp plate 61.

[0071] The implementation principle of a continuous-fire clip applier pliers in the embodiment of the present application is as follows:

[0072] The clamp storage slot 33 contains a plurality of clamps. When the clamp is in use, the operator only needs to pull the trigger 5. The trigger 5 first pushes the tail tube 32 to move forward. The tail tube 32 pushes the upper movable slot 331 to move forward. The elastic push pieces 3311 on the upper movable slot 331 push the tissue clamps at the corresponding positions to move forward. At the same time, the front section of the upper movable slot 331 pushes the front tissue clamps to be pushed into the release clamp plate 61 (and under the action of the thrust, the convex column 212 on the tissue clamp is stuck in the locking slot 222, and the first clamp body 21 and the second clamp body 22 are in a large opening state, which is convenient for clamping). When the tail tube 32 continues to move forward, the transmission boss on the tail tube 32 abuts against the front end of the displacement slot 311, pushing the driving tube 31 to move downward. The driving tube 31 pushes the sliding sleeve 62 to move forward. The sliding sleeve 62 squeezes a pair of release clamp plates 61, thereby pressing and clamping the tissue clamp on the tissue.

[0073] After clamping is completed, the reset spring and the reset plate 63 drive the sliding sleeve 62, the driving tube 31 and the tail tube 32 to reset. During the reset process of each component, the elastic push plate 3311 in the upper movable groove 331 is forced to retract, while the elastic stop plate 3321 in the lower storage groove 332 is against the tissue clamp to prevent the tissue clamp from retreating.
