[0002] The stapler is the world's first suture device and 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. It is generally divided into disposable or multiple-use staplers, imported or domestic staplers. It is a medical device that replaces traditional manual suturing. Due to the development of modern science and technology and the improvement of manufacturing technology, the staplers used clinically are of reliable quality, easy to use, tight, and of appropriate tightness. In particular, they have the advantages of fast suturing, simple operation, and few side effects and surgical complications. They have also made it possible to remove tumors that were previously inoperable.
