Endoscope linear cutting anastomat

Abstract

The invention relates to an endoscope linear cutting anastomat. The endoscope linear cutting anastomat comprises a shell assembly, a percussion assembly, a propelling assembly, a nail box assembly anda rotary positioning sleeve, the percussion assembly is installed on the rear portion of the shell assembly, the propelling assembly is installed in the shell assembly, the nail box assembly is installed at the front end of the shell assembly, and the nail box assembly is connected with the propelling assembly and the percussion assembly; the shell assembly comprises a rear shell and a front gunbarrel. The rotary positioning sleeve is mounted on the front gun barrel and comprises an inner barrel and an outer barrel mounted on the inner barrel, and the outer barrel can rotate around the innerbarrel; and the inner barrel and the front gun barrel are fixed together. According to the endoscope linear cutting anastomat, a traditional rotating head structure is improved to be of a rotating positioning sleeve type, the adjusted angle of the anastomat can be maintained through the rotating positioning sleeve, beneficial conditions are provided for improving operation precision, and operation is convenient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laparoscopic linear cutting stapler. Background technique [0002] With the development of medical technology, the application of medical staplers is becoming more and more extensive. As a category of medical staplers, anorectal stapler has developed various models, such as "A Kind of Anorectal Stapler" disclosed in Chinese Patent Application CN201320215333.7, "Double Push Rod Anorectal Stapler" disclosed in Chinese Patent Application CN201420761577. "And the "Disposable Linear Cutting Stapler" disclosed in Chinese patent application CN201720045978, etc. [0003] The aforementioned stapler solves the problems of practicability and safety to a certain extent, but there are still deficiencies in its convenience of use, especially on the linear cutting stapler, it can not be conveniently converted angles, and the angle cannot be positioned. As described in the "Disposable Line...

AI Technical Summary

Problems solved by technology

[0003] The aforementioned stapler solves the problems of practicability and safety to a certain extent, but there are still deficiencies in its convenience of use, especially on the linear cutting stapler, it can not be conveniently converted angles, and the angle cannot be positioned. As described in the "Disposable Linear Cutting Stapler" disclosed in CN201720045978, when the doctor needs to adjust the angle of the linear cutting stapler relative to the lesion during the operation, he needs to first adjust the rotating head 4 so that the barrel housing 3 can rotate for a certain amount of time. At this time, if the housing 6 is released (the rotating head 4 is always held by human hands), the above-mentioned angle will change, which will affect the surgical accuracy.
