Problems solved by technology

The original instrument already contains a closing handle, a firing handle and an instrument shell handle. If another handle is added for the separation of suturing and cutting, the instrument is very cumbersome and inconvenient for doctors to operate.
If the height of the blade is reduced so that the height of the staples is higher than the height of the blade, the thickness of the tissue that can be clamped by the instrument will be affected during the operation, and the blade will lose the acoustic effect of cutting the backing blade when operating in the low position of the pelvis

Abstract

The invention relates to a closed-excision mechanism used on a curved cutter stapler, which comprises a nail seat, a nail box, a blade, a blade seat, a lateral plate, supporting plates, a main rushing board, auxiliary rushing boards, a pusher and a triggering handle. The triggering handle is movably connected with the main rushing board; the blade is arranged on the blade seat; the blade is fixedly connected with the main rushing board; the pusher is fixedly arranged on the auxiliary rushing boards; two auxiliary rushing boards are provided and are connected with each other through a riveting pin; the main rushing board is positioned between the two auxiliary rushing boards which are inserted in the lateral plate; two supporting plates are provided and are positioned outside the lateral plate, and are connected with each other through the riveting pin. The closed-excision mechanism also comprises a connecting bar plate; a track groove is arranged on the supporting plates; the connecting bar plate is articulated with the main rushing board through a pin, and is connected with the supporting plates through the pin; the pin is positioned in the track groove of the supporting plates; the connecting bar plate is articulated with the auxiliary rushing boards through the pin. The closed-excision mechanism can realize the function that the blade cuts off the tissue after an anastomoses nail sutures the tissue completely, the safety performance is good, and the operation is practical, simple and convenient.

Description

technical field [0001] The invention relates to the field of curved cutting staplers, in particular to a closing mechanism for curved cutting staplers. Background technique [0002] The curved cutting stapler is mainly suitable for low anterior resection of the rectum. In order to enter the lower part of the pelvic cavity, we have developed a curved cutting stapler. The design of this device can better expose the anatomical structure, facilitate deep operation, and the doctor's operation is more in line with the natural physiological anatomy. It can be used in the low anterior resection of the rectum. Get deep into the lower pelvic floor, even into the small pelvis. More importantly, the instrument can complete suturing and cutting in one operation, which simplifies the steps of distal rectum resection. This instrument conforms to the design of ergonomic engineering, and can be closed with one hand, and the positioning pin can be pushed and placed with one hand, so that th...
