Problems solved by technology

This requires the doctor to judge the reasonable degree of tissue compression completely based on experience during the process of closing and firing the stapler mouth, and cannot provide corresponding accurate tissue compression thickness according to the tissue characteristics of different patients.
However, the error in judging the thickness of tissue compression based on experience results in a large dispersion of postoperative effects in different patients. It is difficult to ensure that tissue compression can be in a reasonable nail-forming range for each operation. Once the tissue compression range is unreasonable, there will be Phenomena such as inconsistent nailing and secondary nailing, resulting in postoperative symptoms such as tissue leakage and tissue necrosis, which not only affect the efficiency of the operation, but also cause great pain to the patient

Abstract

The invention discloses an anastomat with a pressure sensing device. The main body of the anastomat is the anastomat. A connecting structure with a strain type pressure sensor is arranged between a nail abutting seat and a rotary knob to achieve mutual linkage. When the rotary knob drives the nail abutting seat to move towards a nail bin and make contact with a barrier, the strain type pressure sensor detects the pressure of the barrier on the nail abutting seat. Compared with the prior art, the anastomat provided by the invention has the advantages that a doctor can accurately judge the optimal opportunity of an operation through provided visual pressure data or alarm, so that the operation threshold of the doctor is reduced; a reasonable tissue squeezing range is provided in an operation, so that the phenomena of inconsistent nailing, secondary nailing and the like are avoided; the operation success rate is improved; the operation risk is reduced; the operation time is shortened, andthe efficiency is improved; and the device can automatically or manually send the information of a postoperative patient to an enterprise cloud platform to carry out statistical analysis on later data, so that the device has an important significance for scientific research of surgical operations.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stapler with a pressure sensing device. Background technique [0002] The medical stapler is a medical device that is often used in performing surgical operations on the physiological tissues of the digestive tract. In general surgery, the stapler is often used to complete the cutting and closing functions of the tissue. The working principle of the stapler is to place the tissue between the staple cartridge and the anvil set, and to squeeze the tissue reasonably by adjusting the distance between the staple cartridge and the anvil set. When the distance between the staple cartridge and the anvil set When the safe range of effective suturing is reached, it is fired, and the U-shaped staples are compressed into a B-shape to suture the tissue. Small blood vessels can pass through the gaps of the B-shaped staples to ensure the blood supply of the anastomosis and distal tissues. ...
