Nail cartridge base of disposable intracavity incision anastomat

Abstract

The invention relates to a nail cartridge base of a disposable intracavity incision anastomat. The nail cartridge base is a matched device of the disposable intracavity incision anastomat for arranging lines on the intracavity tissue and is provided with a circular-arc-shaped nail cartridge base body, wherein a nail cartridge installing groove is arranged on the inner side of the circular-arc-shaped nail cartridge base body. A cutting blade sliding groove is arranged on the circular arc face of the circular-arc-shaped nail cartridge base body, a cutting tool apron sliding groove is arranged on the outer side of the cutting blade sliding groove, nail cartridge fixing grooves are arranged on two sides of the circular-arc-shaped nail cartridge base body, a nail abutting-against seat positioning pin hole is arranged at the back end of the circular-arc-shaped nail cartridge base body, and nail abutting-against seat installing and positioning platforms are arranged on two sides of the back end of the circular-arc-shaped nail cartridge base body. A nail cartridge base locking step is arranged at the back end of the cutting tool apron sliding groove. Due to the fact that the nail cartridge base adopts the circular-arc-shaped nail cartridge base body, two side faces of the back portion of the nail cartridge base are provided with the nail abutting-against seat installing and positioning platforms, two side faces of a nail abutting-against seat and two side faces of the nail cartridge base are smooth, a puncture outfit sealing ring is not damaged by a cutting tool apron in the osculating tissue using process, and an osculating operation is ensured to be performed smoothly.

Description

technical field [0001] The invention relates to a staple cartridge seat of a disposable intracavity cutting stapler, which is a supporting device for the disposable intracavity cutting stapler which applies a line row on the intracavity tissue. Background technique [0002] The current disposable intracavity cutting and stapler anastomosis device passes through the trocar during the use of anastomotic tissue, and the cutting knife seat and the two sides of the anvil seat installed on the needle magazine seat will pull the sealing ring of the trocar. Gas leaks during abdominal inflation, so that the abdominal cavity can no longer be inflated through the puncture device, which seriously affects the normal operation. Contents of the invention [0003] The object of the present invention is to provide a staple cartridge seat for a disposable intracavity cutting stapler in view of the above disadvantages. There is a cutting blade sliding groove, and a cutting knife seat slidin...
