Manual closing electric endoscope anastomat capable of adjusting cutting stroke

Abstract

The invention discloses a manual closing electric endoscope anastomat capable of adjusting a cutting stroke, which is characterized by comprising a gun body mechanism, a rotating piece arranged on the gun body mechanism and a gun barrel piece arranged on the gun body mechanism, the gun body mechanism comprises a shell, a stroke adjusting unit arranged in the shell, a driving unit providing power for the stroke adjusting unit, a cutter returning unit arranged in the shell and a safety unit arranged on the shell, and the gun barrel piece is connected with the end of the stroke adjusting unit. The gun body mechanism composed of the shell, the stroke adjusting unit, the driving unit, the knife returning unit and the safety unit is matched with the rotating piece and the gun barrel piece to form the finished anastomat, and the purposes of reducing the production cost of the anastomat and improving the use quality of the anastomat are achieved.

Description

technical field [0001] The invention relates to the field of stapler production and application, in particular to an electric laparoscopic stapler with an adjustable cutting stroke to manually close. Background technique [0002] At this stage, operations using endoscopic staplers have the advantages of small incision and quick postoperative recovery, while electric endoscopic staplers have the advantages of easy operation and high cutting efficiency, so their market share has been increasing in recent years. [0003] The body of the traditional electric endoscopic stapler can control the suture stroke by monitoring the locked rotor current of the motor, so its body can be compatible with three components of the suture stroke, and its body adopts the working mode of electric closing jaws. The output torque is required to be high, which results in the high cost of the drive motor and the complex control system. [0004] The information disclosed in this Background section is...
