The invention relates to the technical field of medical apparatuses and instruments, and discloses a high-safety anastomat for intestinal tracts, which comprises an operating mechanism, a linkage mechanism, a front-end executing mechanism and a rear-end executing mechanism, one end of the linkage mechanism is arranged in the operating mechanism in a penetrating manner, and the rear-end executing mechanism is arranged at one end, far away from the operating mechanism, of the linkage mechanism; the front-end executing mechanism is arranged on the side, away from the linkage mechanism, of the rear-end executing mechanism, a cutting excitation mechanism is arranged, a spring limiting lock pin enters a lock hole formed in the bottom end of an arc limiting groove under the action of a lock pin spring, movement of an annular blade is limited by limiting movement of a steel cable, and a blade containing groove is formed, after the excision step is completed, the annular blade enters the blade storage groove and is fixed under the limitation of the spring fixing block, so that the annular blade is effectively stored, and the situation that the annular blade is exposed outside and easily causes secondary injury to a patient is avoided.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an intestinal stapler with high safety. Background technique [0002] Stapler is a medical surgical stapler, which is used in medicine to replace traditional manual suturing equipment. Due to the development of modern technology and the improvement of manufacturing technology, the main working principle is to use titanium nails to separate or anastomose tissues. Similar to the structure of a stapler. According to the scope of application, it can be mainly divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, blood vessel staplers, lung cutting staplers, etc. Stapler usually has the advantages of convenient use, tightness, and suitable tightness, especially its fast suturing, easy operation, and few side effects and surgical complications, etc., and has been more and more widely used. [0003] Common intestina...
