Needle stitch removing device for obstetrical and gynecological operation

Abstract

The needle thread removing device structurally comprises a pull handle, a fixed handle, a connecting shaft and a cutting mechanism, the upper end of the pull handle is hinged to the upper end of the fixed handle through the connecting shaft, the right end of the cutting mechanism is fixed to the upper end of the pull handle, a closing piece abuts against a needle thread at a wound, and the needle thread extends into a cutter mechanism; the cutter mechanism and a surgical suture wound can be separated through the closing piece, and meanwhile, the sliding block drives the fixing plate to elastically slide up and down along the spring rod, so that contact extrusion between the lower end of the cutter mechanism and the surgical suture wound is avoided, the surgical suture wound is prevented from cracking again, and a telescopic hose is prevented from shrinking and extruding; the air pressure in the liquid guide pipe is changed, at the moment, the disinfectant stored in the liquid guide pipe is sprayed out downwards from the interior of the nozzle, it is ensured that the blade mechanism keeps the disinfection cleanliness all the time in the process of detaching and cutting the needle and thread, and secondary infection of a surgical suture wound is prevented.

Description

Technical field [0001] The present invention involves the field of obstetrics and gynecology, and more specifically, especially the needle demolition device for obstetrics and gynecology surgery. Background technique [0002] Gynecological minimally invasive surgery, as the name implies, is to reduce the damage of surgery on normal tissue as much as possible, minimize the impact of surgery on the function of all systems of the whole body. During gynecological surgery, you need to sew pins on wounds. The wire device removes the needle wire, but because the needle removal device of the needle uses a wire disassembly and cutting method, the needle wire is cut and cut. The micro -invasive wound is very small. In contact with the wound, it caused secondary cracks to the wound during the cutting process. At the same time, the needle demolition device needs to be disinfected during the cutting process. During the cutting process, the disinfection effect of the needle removal device grad...

Problems solved by technology

[0002] Gynecological minimally invasive surgery, as the name implies, is to minimize the damage to normal tissues and minimize the impact of surgery on the functions of various systems in the body. During gynecological surgery, it is necessary to suture the wound. The thread device removes the needle and thread, but because the needle thread removing device adopts the method of thread removing scissors to cut the needle and thread, the minimally invasive wound is small, and the needle thread removing device will also contact the needle and thread at the suture of the wound at the same time. Contact at the wound causes secondary cracking of the wound during the cutting process. At the same time, the needle suture removal device needs to be sterilized during the cutting process. During the cutting process, the disinfection effect of the needle suture removal device itself gradually declines, making it difficult to Keep clean at all times, which may easily lead to secondary infection of the wound during the stitch removal process
