An Electric Endoscopic Stapler Against Misfire

Abstract

The invention discloses an electric endoscopic stapler for preventing misfiring, which comprises a gun body, a wire block, a threaded rod and an antimisfire mechanism. A firing handle is movable, one side of the firing handle is movable with an adjusting handle, one side of the wire block is fixed with a fixed handle, one end of the threaded rod is fixed with an adjusting disc, and the other end of the threaded rod is fixed through the installation frame and The wire block is rotatably connected to one side of the inner wall of the installation frame, and one end of the installation frame is fixedly connected to the lower side of the gun body. The electric endoscopic stapler for preventing false firing is provided with a first installation groove, through which the first installation groove is connected. , The effect of fixing and concealing the installation, so as to avoid that some parts in the anti-misfire mechanism need to be fixedly connected and installed through auxiliary installation parts, which not only affects the appearance of the overall gun body, but also affects the overall operation progress during the operation of the overall gun body Case.

Description

technical field [0001] The invention relates to the technical field of electric endoscopic staplers, in particular to an electric endoscopic stapler for preventing false firing. Background technique [0002] Laparoscopic stapler (laparoscopic cutting stapler and disposable staple cartridge) is one of the important instruments in endoscopic surgery. It replaces traditional manual suture and uses titanium staples to cut off or anastomose tissue. The operation time is shortened, and the endoscopic stapler makes the anastomosis with narrow operating field and deep parts easy, accurate, firm and reliable, and significantly reduces the incidence of anastomotic leakage. Since its birth, the device has undergone many design improvements, from the original medical "stapler" to a stapler, and started after going through two technical stages of the first generation of open staplers and the second generation of endoscopic staplers. Entering the era of the third-generation electric endo...

Problems solved by technology

[0003] The object of the present invention is to address the deficiencies of the prior art, and provide an electric endoscopic stapler that prevents misfiring, so as to solve the problems of the existing electric endoscopic stapler proposed in the above-mentioned background technology due to the failure of the firing handle and the adjustment handle. The installation location is close, and the firing handle needs to be pressed repeatedly for surgical operation during the operation, which will easily cause the operator to press the firing handle again according to the operation memory after the operation, and at the same time cause the wrong firing process of the firing handle, which in turn will easily lead to surgical danger. Due to the fact that the existing electric endoscopic stapler has a certain installation distance from the fixed handle, the firing handle and the adjusting handle, different operators need to manually hold the fixed handle, the firing handle and the adjusting handle for operation. The problem of constantly adjusting the direction and angle of the handle to affect the progress of the overall operation
