Description

Technical Field

[0001] The invention relates to the technical field of medical devices and in particular to a double-arm suture clamp capable of closing a wound surface. Background Art

[0002] At present, when performing digestive tract surgery under flexible endoscopy, especially when performing mucosal stripping surgery, it is easy to cause tissue perforation, such as gastric perforation and intestinal perforation. Once perforation occurs, it is very difficult to remedy it under endoscopy, which will cause great risks to patients. When using existing suture clips, multiple suture clips are required to cooperate with nylon ropes to suture tissue wounds. In this way, it is necessary to clamp each suture clip at the required position of the tissue first, and then pull the suture clips together through the nylon rope to close the wound, which greatly prolongs the operation time, reduces work efficiency, and causes great trauma to patients. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that when the existing suture clamps are used, multiple suture clamps are needed to cooperate with nylon ropes to suture tissue wounds, so that the suture clamps need to be clamped at the required positions of the tissues one by one, and then the suture clamps are pulled together by the nylon ropes to close the wounds, which greatly prolongs the operation time, reduces the work efficiency, and causes great trauma to the patients. A double-arm suture clamp that can close the wound is provided.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a double-arm suture clamp capable of closing a wound, comprising a control component and an upper suture clamp component and a lower suture clamp component relatively arranged on the control component, and also comprising a sleeve, wherein the upper suture clamp and the lower suture component both comprise a splint, a chuck, a front locating pin and a rear locating pin, wherein the splint passes through both ends of the sleeve, the front locating pin and the rear locating pin are respectively arranged at both ends in the sleeve, one end of the chuck is arranged on the splint, the front locating pin is located between the splint and the chuck, and the chuck is located between the front locating pin and the rear locating pin, and the control component is respectively provided with slip rings corresponding to the upper suture assembly and the lower suture assembly, one end of the splint is arranged on the slip ring, and when the slip ring controls the splint to move along the front locating pin to the rear locating pin, the chuck gradually moves closer to the splint under the action of the front locating pin and the sleeve. When the front positioning pin causes the sliding ring to push the suture assembly forward, the splint and the chuck are relatively open, and when the rear positioning pin causes the sliding ring to pull the suture assembly, the chuck and the splint are relatively close and can clamp the tissue between the splint and the chuck. In this way, the chucks and splints on both sides of the suture assembly clamp the tissues on both sides respectively, so that one suture assembly can be used twice and clamp the tissue, which greatly improves the efficiency of the operation, reduces the use of medical equipment, improves work efficiency, and reduces the pain of patients.

[0005] In order to facilitate the separation of the suturing assembly and the control assembly, the control assembly further includes a fixed seat, a connector, a spring tube and a core rod, a release notch is opened on the splint, a rivet matching the release notch is arranged on the splint, the release notch is arranged on the rivet, the slip ring is slidably arranged on the fixed seat, one end of the sleeve close to the rear positioning pin is detachably connected to one end of the connector, the other end of the connector is slidably connected to the fixed seat, and the end of the fixed seat close to the connector is provided with a limiting shoulder for limiting the displacement of the connector toward the sleeve, the two ends of the splint pass through the connector, the spring tube is sleeved on the splint, one end of the spring tube is abutted against the connector, the other end of the spring tube is arranged on the core rod, and the slip ring is slidably arranged on the core rod. By cooperating with the rivet on the splint through the release notch on the splint, when the slip ring is pulled, one end of the connector slides in the fixed seat and exerts a reverse force on the sleeve, and the reverse force forces the connector to separate from the sleeve. At the same time, there will be a reverse force at the connection between the splint and the chuck, so that the release notch of the chuck will be separated from the rivet on the splint under the reverse force, so that the splint and the chuck are separated, and the sleeve and the connector are separated, so that the chuck and the sleeve maintain the clamping organization, and the control component and the splint are taken out.

[0006] In order to save medical costs and improve the utilization rate of the equipment, further, a butt-joint pipe, a cable and a booster pipe are arranged between the splint and the slip ring, one end of the butt-joint pipe is fixedly connected to the splint, the other end of the butt-joint pipe is fixedly connected to the cable, one end of the cable is fixedly connected to the booster pipe, and one end of the booster pipe is fixedly connected to the slip ring. The cable is connected to the splint through the butt-joint pipe, so that the cable can be separated from the splint, so that the control component can be disinfected and can be used again with the suture component to be used, so as to improve the utilization rate of the control component.

[0007] In order to ensure that the clamping of the chuck is stable and reliable, a bayonet is provided on one side of the chuck close to the front positioning pin, and the bayonet is located outside the sleeve. When the chuck is retracted to the sleeve and clamps the tissue, the front positioning pin is located inside the bayonet. Since the chuck needs to be retained in the human body, and the sleeve can only constrain the chuck in one direction, in order to ensure that the chuck is clamped stably, a bayonet is provided on the chuck, and the bayonet cooperates with the front positioning pin, thus increasing a radial restraining force on the chuck, thus ensuring that the chuck is stable and reliable, and avoiding the phenomenon that the chuck is separated from the tissue clamping and the chuck is separated from the sleeve.

[0008] The beneficial effects of the present invention are as follows: when the double-arm suture clamp capable of closing a wound surface is in use, when the front positioning pin causes the sliding ring to push the suture assembly forward, the splint and the chuck are relatively opened, and when the rear positioning pin causes the sliding ring to pull the suture assembly, the chuck and the splint are relatively brought close to each other and can clamp the tissue between the splint and the chuck, so that the chucks and the splints on both sides of the suture assembly clamp the tissues on both sides respectively, so that one suture assembly can be used twice and can clamp the tissue, thus greatly improving the surgical efficiency, reducing the use of medical equipment, improving the work efficiency, and reducing the pain of the patient.

The chuck 3 is provided with barbs, which are used to facilitate the chuck 3 to penetrate into the desired position of the tissue and keep the chuck 3 clamped stably and reliably. The chuck 3 is provided with fixed thorn openings.

[0031] The control component includes a fixed seat 7, a connector 8, a spring tube 9 and a core rod 10. A release notch 11 is provided on the chuck 3, a rivet 12 matching the release notch 11 is provided on the splint 2, the release notch 11 is arranged on the rivet 12, the slip ring 6 is slidably arranged on the fixed seat 7, one end of the sleeve 1 close to the rear positioning pin 5 is detachably connected to one end of the connector 8, the other end of the connector 8 is slidably connected to the fixed seat 7, the end of the fixed seat 7 close to the connector 8 is provided with a limiting shoulder 13 for limiting the displacement of the connector 8 toward the sleeve 1, both ends of the splint 2 pass through the connector 8, the spring tube 9 is sleeved on the splint 2, one end of the spring tube 9 is abutted against the connector 8, the other end of the spring tube 9 is arranged on the core rod 10, and the slip ring 6 is slidably arranged on the core rod 10.

[0032] It also includes a butt-joint pipe 14, a cable 15 and a booster pipe 16 arranged between the clamping plate 2 and the slip ring 6, one end of the butt-joint pipe 14 is fixedly connected to the clamping plate 2, the other end of the butt-joint pipe 14 is fixedly connected to the cable 15, one end of the cable 15 is fixedly connected to the booster pipe 16, and one end of the booster pipe 16 is fixedly connected to the slip ring 6. The butt-joint pipe 14 may also be unnecessary, and the cable 15 and the tail of the clamping plate 2 can be directly welded, which reduces the installation steps of the staff, improves the work efficiency, and reduces the space occupied by the components.

[0033] A bayonet is provided on one side of the chuck 3 close to the front positioning pin 4 , and the bayonet is located outside the sleeve 1 . When the chuck 3 is retracted into the sleeve 1 and clamps the tissue, the front positioning pin 4 is located in the bayonet.

[0034] like Figure 8-17As shown, when the double-arm suture clamp capable of closing a wound surface is used, the core rod 10 and the slip ring 6 on the fixing seat 7 are first pushed to move relative to each other, so that both slip rings 6 slide on the core rod 10, and drive the splint 2 to extend out of the sleeve 1 through the booster tube 16, the cable 15 and the butt joint tube 14. At this time, the splint 2 is gradually opened relative to the splint 2 under the action of the front positioning pin 4, and the clamp 3 on one side is inserted into the tissue to be clamped, and then one of the slip rings 6 is pulled to make the slip ring 6 slide on the core rod 10, and the slip ring 6 drives the corresponding booster tube 16, the cable 15 and the butt joint tube 14, and then the butt joint tube 14 drives the splint 2 to move, and the splint 2 gradually shrinks into the sleeve 1, and under the action of the rear positioning pin 5 and the sleeve 1, the chuck 3 gradually moves closer to the splint 2, and the chuck 3 on one side of the suture assembly clamps the tissue, and then controls another slip ring 6 to slide on the core rod 10, and the slip ring 6 drives the corresponding booster tube 16, the cable 15 and the butt joint tube 14, and then the butt joint tube 14 drives the splint 2 to move, and the splint 2 gradually shrinks into the sleeve 1, and under the action of the rear positioning pin 5 and the sleeve 1, the chuck 3 gradually moves closer to the splint 2, and the chuck 3 on the other side of the suture assembly clamps the tissue;

[0035] At this time, the clamps 3 on both sides of the suturing assembly clamp the tissue, and then simultaneously pull the two slip rings 6 to move on the core rod 10. Since a bayonet is provided at one end of the rear locating pin 5 at the far end of the clamp 3, the front locating pin 4 is located between the bayonet and the rear locating pin 5. When the front locating pin 4 is located in the bayonet, the slip ring 6 continues to pull the splint 2, thereby applying a reverse force to the clamp 3. The reverse force causes the release notch 11 of the clamp 3 to disengage from the rivet 12 of the splint 2, and one end of the connector 8 disengages from the sleeve 1 under the action of the reverse force. At this time, the splint 2 and the clamp 3 are disengaged, and The connector 8 is disengaged from the sleeve 1, and the core rod 10 of the control assembly is pulled. The chucks 3 on both sides of the suturing assembly always keep the tissue clamped under the action of the sleeve 1, so that the wound can be clamped twice by one suturing assembly, which reduces the operation time and improves the work efficiency. At the same time, a barb 17 is provided at one end of the chuck 3, and a notch corresponding to the barb 17 is provided on the sleeve 1. When the clip 3 is clamped, the barb 17 moves toward the notch direction, and finally the barb 17 is stuck in the notch, which fixes the chuck 3 and effectively prevents the chuck 3 from loosening, thereby playing a double protection role.
