Their effects on the human body surface and body are not achieved by pharmacological, immunological or metabolic means, but these means may be involved and play a certain auxiliary role. Patients with gastrointestinal diseases will be sutured with a stapler. The stapler is the world's first stapler and has been used for gastrointestinal anastomosis for nearly a century. It is generally divided into disposable or multiple-use staplers, imported or domestic staplers. It is a device used in medicine to replace 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.
