[0002] The stapler is the world's first suture device, which has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. Generally, it is divided into disposable or reusable staplers, imported or domestic staplers. It is a device used in medicine to replace traditional manual suture. Due to the development of modern technology and the improvement of manufacturing technology, the staplers used clinically are reliable in quality, convenient to use, tight and appropriate in tightness. Especially, its advantages such as fast suture, simple operation, few side effects and surgical complications also enable the resection of tumors that could not be removed in the past. When using the stapler, a safety structure of a linear cutting stapler is required to prevent accidental touch of the stapler trigger.
