Abstract

The invention provides a measuring device and method for triggering force and closing force of an endoscopic stapler. The measuring device for the triggering force and the closing force of the endoscopic stapler includes a bearing part, a clamping part, a triggering force measuring part, a closing force measuring part, a data processing and display part and an L-shaped plate. The measuring deviceand method for the triggering force and the closing force of the endoscopic stapler have the characteristics of simple structure and convenient operation, the endoscopic stapler can be clamped, and the triggering force and the closing force are automatically measured.

Description

technical field [0001] The invention relates to a device for measuring the pulling force and closing force of an endoscopic stapler, and also relates to a method for measuring the pulling force and closing force of an endoscopic stapler, belonging to the field of medical devices. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers , Lung cutting stapler, etc. [0003] The trigger force and chuck closing force of the endoscopic stapler have an important impact on the stability and comfort of the doctor during the operation, as well as the occasion and scope of use of the st...
