An endoscope cutting stapler with adjustable jaw direction

Abstract

The invention discloses a laparoscopic cutting stapler with adjustable jaw direction, which relates to the field of laparoscopic cutting staplers, comprising a mounting cylinder, one end of which is fixedly mounted with two symmetrical arc-shaped blocks, wherein The top side of one of the arc blocks is rotatably mounted with a rotating block. In the present invention, the rotation of the rotating rod drives the turntable to rotate, the turntable drives two fixed rods to rotate, the two fixed rods drive the cylindrical block to rotate, the rotation of the cylindrical block drives the rotating rod to rotate, the rotation of the rotating rod drives the helical gear to rotate, and the helical gear rotates. The rotation of the gear drives the driven gear to rotate, and the rotation of the driven gear drives the rotating block and the bottom plate to rotate, and then the jaw can be adjusted to rotate left and right, so that it can accurately approach the cutting position. The L-shaped pull rod moves to drive the T-shaped column to move, and the T-shaped The column moves to drive the stay cord to move, and the stay cord moves to drive the mounting block and the clamping plate to rotate, so that cutting can be performed.

Description

technical field [0001] The invention relates to the field of laparoscopic cutting staplers, in particular to a laparoscopic cutting stapler with adjustable jaw direction. Background technique [0002] Laparoscopic cutting and stapler is suitable for resection, transection and anastomosis of tissues in abdominal, gynecological, pediatric and thoracic surgery, and can also be used for resection and transection of liver parenchyma, liver blood vessels and gallbladder ducts. The cutting stapler is composed of pin, rod, joint head knob, rotating collar, green firing button, black recovery button, light blue unloading button, ring handle and accessories. The accessories are disposable tip curved rotatable nail magazine and disposable Rotatable nail magazine. When operating the laparoscopic cutting stapler and its components for surgery, it is necessary to use the stapler component to close the free blood vessels and other tissues through the narrow space of the tissue.

AI Technical Summary

Problems solved by technology

[0004] The jaws of the above-mentioned endoscopic cutting stapler in the prior art are fixed and cannot be adjusted. During the operation, the jaws cannot be flexibly and accurately approached to the cutting position, resulting in a long time for surgery, especially during cutting. The cutting position cannot be clamped, causing the cutter to deviate from the cutting position during cutting, which makes the patient's condition worse due to cutting errors, and it is not easy to install and disassemble, which delays patients who need emergency surgery, and there is no card to connect the drawstring buckle so that the unit cannot be disassembled
