AI Technical Summary

Technical Problem

Existing transoral insertion of anvils is difficult to operate in clinical applications, traction is time-consuming and laborious, and it is easy to cause esophageal damage. It also lacks a structure that can stably fix intestinal tissue.

Method used

An anastomosis assembly was designed, including an anvil, a traction tube, and a traction wire. The anvil is guided to move by a guide shaft and an auxiliary puncture head. The auxiliary puncture head punctures the digestive tract stump. The traction wire pulls the guide shaft to expose it. An expansion ring fixes the digestive tract stump. When the annular anvil surface is anastomosed with the staple cartridge, it provides tissue-accommodating space to ensure the neatness and firmness of the anastomosis.

Benefits of technology

It achieves accurate traction of the anvil, avoids directional deviation and damage to the digestive tract, and is simple and quick to operate, improving the suturing efficiency and anastomosis effect of surgical procedures.

Abstract

The anastomosis assembly comprises a nail abutting seat, a traction tube and a traction line, the nail abutting seat comprises a nail abutting seat top cover, a guide shaft and an auxiliary puncture head which are connected in sequence, the traction tube is connected to the nail abutting seat top cover, and the traction line is connected to the auxiliary puncture head; the anastomat comprises an anastomat body, a nail bin and a puncture needle, the anastomat body is provided with an adjusting device used for adjusting the position of the puncture needle and a percussion device used for pushing out suturing nails in the nail bin, the anastomat further comprises the anastomosis assembly, the auxiliary puncture head is detachably connected to the guide shaft, and the puncture needle is connected with the guide shaft where the auxiliary puncture head is detached in a matched mode. And a top cover of the nail propping seat is matched with the nail bin. According to the utility model, the nail propping seat can be smoothly and accurately dragged to an anastomosis part, the direction is not easy to deviate in the traction process, the digestive tract is not easy to damage, the operation is simple, convenient and quick, the time and labor are saved, the anastomosis effect is good, and the suture efficiency of a doctor in a surgical operation is further improved.
