Through the rivet on the release breach cooperation splint on the splint, simultaneously when pulling the sliding ring, the one end of connector slides in the fixing base to apply a reverse effort to the sleeve, force connector and sleeve separation at reverse effort, splint and chuck junction also have reverse effort simultaneously, make the release breach of chuck break away from the rivet of splint under reverse effort, just so make splint and chuck separate, sleeve and connector separate simultaneously, make chuck and sleeve keep holding the centre gripping tissue, and make control assembly and splint take out.
In order to save medical cost and improve the utilization rate of equipment, the device further comprises a butt joint pipe, a pull rope and a boosting pipe, wherein the butt joint pipe, the pull rope and the boosting pipe are arranged between the clamping plate and the sliding ring, one end of the butt joint pipe is fixedly connected to the clamping plate, the other end of the butt joint pipe is fixedly connected to the pull rope, one end of the pull rope is fixedly connected with the boosting pipe, and one end of the boosting pipe is fixedly connected with the sliding ring. The stay cable is connected with the clamping plate through the butt joint pipe, so that the stay cable can be separated from the clamping plate, the control assembly is disinfected, the suture assembly to be used is matched with the stay cable to be reused, and the utilization rate of the control assembly is improved.
In order to ensure stable and reliable clamping of the clamping head, further, a bayonet is formed in one side, close to the front locating pin, of the clamping head, the bayonet is located outside the sleeve, and when the clamping head contracts to the sleeve and clamps tissues, the front locating pin is located in the bayonet. Because the clamping head needs to be kept in the human body, the sleeve can only restrict the clamping head in one direction, in order to ensure the clamping stability of the clamping head, the clamping opening is formed in the clamping head and matched with the front positioning pin, so that the binding force of the clamping head in the radial direction is increased, the sub-stability and reliability of the clamping head are ensured, and the phenomenon that the clamping head is separated from the tissue clamping and separated from the sleeve is avoided.
The double-arm suture clamp capable of closing the wound surface has the advantages that when the double-arm suture clamp capable of closing the wound surface is used, when the front locating pin enables the slip ring to push the suture assembly forwards, the clamping plate and the clamping head are relatively opened, when the rear locating pin enables the slip ring to pull the suture assembly, the clamping head and the clamping plate are relatively close and can clamp tissues between the clamping plate and the clamping head, so that the clamping heads and the clamping plates at two sides of the suture assembly respectively clamp the tissues at two sides, one suture assembly can be used for two times and clamp the tissues, the operation efficiency is greatly improved, the use of medical instruments is reduced, the working efficiency is improved, and the pain of a patient is also reduced.
