Endoscope cutting anastomat with nail anvil capable of moving up and down and rotating

Abstract

The invention discloses an endoscopic cutting anastomat with a nail anvil capable of moving up and down and rotating, and belongs to the technical field of anastomats. The endoscopic cutting anastomat comprises a holding handle, a safety button is arranged at the upper end of the holding handle, a mounting shell is arranged at the upper end of the safety button, a nail bin assembly is arranged on one side of the mounting shell, and the nail bin assembly is arranged on the other side of the mounting shell. A percussion handle is arranged on one side of the holding handle, a limiting and locking assembly is arranged on the surface of the holding handle corresponding to the percussion handle, the limiting and locking assembly comprises a mounting frame, a connecting rod, a limiting clamping block, a stop block, a guide groove and a limiting spring, the mounting frame is arranged on one side of the surface of the holding handle, and guide grooves are symmetrically formed in the mounting frame. By arranging the limiting and locking assembly, it is guaranteed that the percussion handle is locked stably, the squeezing effect is improved, the sewing quality is guaranteed, manpower resources are saved, the movement convenience of the percussion handle is improved, the use quality is guaranteed, and the working intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of staplers, in particular to a laparoscopic cutting stapler with an anvil that can move up and down and rotate. Background technique [0002] Laparoscopic stapler (endoscopic cutting stapler and disposable nail box) is one of the important instruments in laparoscopic surgery. It replaces traditional manual suture and uses titanium nails to separate or anastomose tissues. It is easy and fast to operate and greatly The operation time is shortened. The laparoscopic stapler makes the operation field narrow, and the manual anastomosis of deep parts is easy, accurate, firm and reliable, and the incidence of anastomotic leakage is significantly reduced. [0003] There are following problems in prior art: [0004] 1. The existing anvil can move up and down and rotate the endoscopic cutting stapler, which cannot limit the firing handle during use, which affects the stability of the firing handle, reduces the squee...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing anvil can move up and down and rotate the endoscopic cutting stapler, which cannot limit the firing handle during use, which affects the stability of the firing handle, reduces the squeezing effect, affects the quality of the operation, and wastes human resources;

[0005] 2. After the adjustment knob is turned, the adjustment knob cannot be fixed, and it is easy to be skewed due to mistouch, which reduces the quality of the operation and affects the suture effect;

[0006] 3. When the push block needs to be pulled, it is necessary to pull the push block with finger rests on both sides of the installation shell, which wastes human resources, affects the pulling quality, makes work inconvenient, and costs high
