Percussion force tester for linear cutting anastomat

Abstract

The invention relates to a percussion force tester for a linear cutting anastomat. The percussion force tester is a test instrument used for detecting the magnitude of force during osculating percussion of the linear cutting anastomat and the magnitude of force of anastomotic nail anastomotic tissue and cutting knife cutting tissue. The tester comprises a case, a testing device, a testing tool anda toggle clamp, wherein the testing device is mounted on a bottom plate of the case, a workbench is arranged at the upper part of the case, the upper part of the testing device is exposed at the upper part of the workbench of the case, the testing tool is mounted on the workbench surface and is used for mounting and fixing a tested linear cutting anastomat, and the toggle clamp is mounted on theworkbench at one side of the testing tool and is used for pressing and fixing the front part of the tested linear cutting anastomat; the testing tool is installed on the upper portion of the workbenchand provided with an anastomat installation bottom plate, and positioning blocks are installed on the two sides of the anastomat installation bottom plate and used for installing and positioning thelinear cutting anastomat.

Description

technical field [0001] The invention relates to a firing force tester of a linear cutting stapler, which is a testing instrument for detecting the force of the linear cutting stapler when it is fired, and the force of staples for anastomotic tissue and cutting knife for cutting tissue. Background technique [0002] The linear cutting stapler is a one-time use without power supply, and only relies on mechanical force to cut human tissue. There is a pushing mechanism with a push button at the end of the instrument, which is used to realize the reciprocating linear motion of cutting and suturing. Due to the advantages of simple operation, safe and reliable suture, light tissue damage and few sequelae in clinical use, the linear cutting stapler is widely used in digestive tract surgery. Because of its use, it not only shortens the operation time, but also improves the operation quality, so that both doctors and patients are satisfied, and outstanding economic and social benefit...

AI Technical Summary

Problems solved by technology

[0003] At present, the production and assembly of linear cutting staplers and the delivery of finished products lack a firing force tester to detect the anastomosis of linear cutting staplers and the firing force of the cutting push button. The driving force is too small, the tissue cut is incomplete, and the staples are not closed, which affects the success rate of the operation

There is also a situation where the staples are too tight to anastomose tissues due to the excessive force of the cutting push button, which damages some tissues.

After anastomosis and cutting with a linear cutting stapler, the tissue blood supply is not smooth, and the wound recovery is relatively slow, which brings unnecessary pain to the patient
