Background

The anastomat is a device used in medicine to replace manual suture, and the main working principle is to use titanium nails to perform separation or anastomosis on tissues. When the anastomat is used for anastomosing tissues, anastomosis nails are needed to be used and are arranged in the nail bin, and the tissues are stapled together through the anastomosis nails, so that anastomosis is realized. Because the thickness of different parts of human tissue is different, the anastomosis nail also has multiple models, and the corresponding anastomosis nail is selected according to different tissue thicknesses. At present, when the staple cartridge is selected, the judgment can be usually carried out only by the observation and experience of a doctor, and the doctor selects the corresponding staple cartridge according to the tissues needing anastomosis by means of the experience accumulated for many years and the knowledge of the stapler. However, since the actual thickness of different tissues is difficult to accurately judge by naked eyes, judgment errors are easy to occur; and the selection of the anastomotic nail mainly depends on subjective factors, so doctors with insufficient experience or unfamiliar with the anastomat have difficulty in selecting the anastomotic nail.
