Abstract

The invention relates to an intelligent anastomat which comprises an electric clamping transmission component, a manual excision-closed transmission component, an executor steering transmission component, a nail bin support (16), a nail supporting seat (17), a short connecting pipe (14), a connecting pipe (13), a movable handle (39) and a fixed handle (40), a control module is arranged on the nailsupporting seat (17), the short connecting pipe (14) and the connecting pipe (13) are connected with the nail bin support (16) and an adjusting shell (36), the movable handle (39) and the fixed handle (40) are arranged at the rear end of the adjusting shell (36), a handle (25) and a battery (45) are connected below the fixed handle (40), and a pull-back block (49) and an external power supply line (55) are arranged on the movable handle (39). Compared with the prior art, the intelligent anastomat can really reduce subjective participation of doctors, use of the anastomat is more standardized,so that harmful effects caused by lack of experience of users are avoided, and anastomosis success rate is increased.

Description

technical field [0001] The invention belongs to the field of medical devices. More specifically, the invention is an intelligent electric stapler capable of controlling the automatic squeezing process of the tissue by the stapler by detecting the squeezing parameters of the tissue. Background technique [0002] Digestive tract reconstruction is one of the most important steps in gastrointestinal surgery. After removing part of the gastrointestinal tissue, the doctor needs to anastomose the remaining part to re-form a continuous digestive tract. The methods of digestive tract reconstruction include manual anastomosis and mechanical anastomosis; manual anastomosis is manual suture, and mechanical anastomosis is based on various staplers. The stapler can drive in two or three rows of cross-arranged staples on both sides of the tissue at the same time, and then use a push knife to cut and separate the sutured tissues on both sides, and complete suturing, hemostasis and cutting a...
