Abstract

The invention discloses an automatic advancing and manual retreating mechanism of an electric endoscope anastomat. The automatic advancing and manual retreating mechanism of the electric endoscope anastomat comprises a support frame, wherein the motor is mounted on one side of the support frame; a lead screw is arranged at one end of an output shaft of the motor; a lead screw nut is connected to the outside of the lead screw in a sleeving manner; the lead screw nut is in sliding fit with the support frame; a clutch device is arranged outside the lead screw and comprises a first bevel gear which is slidably arranged on the lead screw in a sleeving manner; the output shaft of the motor and the lead screw rotate synchronously through the first bevel gear; a clutch button is slidably arrangedon the support frame; one side of the clutch button is hinged to a clutch handle; the outer wall of the lead screw is provided with a flange; one end of the lead screw is connected with a first elastic element in a sleeving manner; the first elastic element is in contact with the flange; one end of the clutch handle is hinged to one side of the first bevel gear; and one side of the support frame is provided with a retreating device. The automatic advancing and manual retreating mechanism of the electric endoscope anastomat has the characteristics of strong practicability and stability in operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic advancing and manual retracting mechanism of an electric endoscopic stapler. Background technique [0002] With the development of science and technology and the improvement of medical conditions, surgical operations are also developing towards refinement and minimal invasiveness. Especially in the past ten years with the rapid development of camera technology, minimally invasive surgery has been widely used. The use of laparoscopic medical devices in invasive surgery only needs to make 1-3 small holes of 1.5 cm in the corresponding parts of the patient to complete the resection and anastomosis of tumors, lesions and other lesions. At present, the manual endoscopic stapler is still the mainstream, which has certain requirements for the doctor's actual operation technique. Improper operation will cause the pulling and tearing of the sutured tissue, and the for...
