Memory hemostatic clip and distraction-type clamping dual-purpose clip applier and clip holder

Abstract

The invention discloses a memory hemostatic clip and distraction-type clamping dual-purpose clip applier and a clip holder. The memory hemostatic clamp comprises two clamping arms with automatic clamping elasticity, the two clamping arms are in a clamping state; the holder is used for storing the memory hemostatic clip; the distraction-type clamping dual-purpose clip applier comprises a clip opening and closing device and a handle assembly, the forceps holder opening and closing device is in transmission connection with the handle assembly; the normal state of the forceps clip opening and closing device is a closed state, the handle assembly comprises a driving handle, when the driving handle is pulled, the clip opening and closing device is opened to take down the memory hemostatic clip from the clip holder, and when the target tissue is clamped, the driving handle is loosened, and the memory hemostatic clip clamps the target tissue under the action of the elasticity of the memory hemostatic clip and the closing restoring force of the clip opening and closing device. The product has the dual-purpose integrated function of clip applying and clip taking, the hemostatic clip does notneed to be cut off through a secondary repair operation, mechanical damage and injuries are avoided, and the product is safer and high in efficiency.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a memory hemostatic clip and a clip applier and a clip base for dual-purpose use of expansion type clipping. Background technique [0002] The hemostatic clip is a surgical instrument that achieves blood blocking by clamping blood vessels, and the clip applier is used to hold the hemostatic clip. After the existing hemostatic clips are clipped, secondary repair operations are often required to cut off the hemostatic clips, resulting in mechanical damage and secondary injuries. Moreover, it is difficult to hold the existing clip appliers, and it is time-consuming and laborious to use clip appliers to clamp the hemostatic clips. In addition, the hemostatic clip and the clips of the clip applicator are not tightly matched, and the hemostatic clip is easy to break away from the clip. Contents of the invention [0003] The purpose of the present invention is to overcome the deficienc...
