Electric stapler

Abstract

The invention discloses an electric stapler comprising an osculating mechanism and a drive actuator. The drive actuator comprises a rear drive mechanism and a front actuator connected through a quick connection mechanism. The rear drive mechanism comprises a rear pipe, a rear push pipe, and a rear central rod; the rear push pipe is disposed inside the rear pipe and can be driven to screw back and forth; the rear central rod is disposed at the center of the rear push pipe and can be driven to screw back and forth. The front actuator comprises a front pipe, a front push pipe, and a front central rod; the front push pipe is disposed inside the front pipe and can be driven to screw back and forth; the front central rod is disposed inside the front push pipe and can be driven to screw back and forth. The quick connection mechanism comprises a sleeve, first grooves and ribs, and second grooves and ribs; the front and rear pipes are fixedly connected through the sleeve; the first grooves and ribs are arranged on opposing faces of the front and rear push pipes correspondingly; the second grooves and ribs are arranged on the opposing faces of the front and rear central rods correspondingly. The electric stapler is simple in structure and highly practicable, an osculating head can be changed fast, the rear of the stapler can be reused, and usage cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an electric stapler. Background technique [0002] The medical stapler is a medical device that is often used when performing surgical operations on the physiological tissues of the digestive tract. Now the commonly used staplers are all manually operated in the process of "closing, stapling, and cutting" the physiological tissues. Usually, the manual operation steps It is cumbersome, prone to misoperation, or causes surgical failure. In addition, due to individual differences, the degree of tissue closure and closure time are likely to be inconsistent during manual closing operations, and the firing force during firing operations will vary greatly, thereby reducing the quality of surgery. [0003] In order to overcome manual deficiencies, Chinese patent 201110109722.7 discloses a surgical electric stapler, which includes an anastomotic part with an abutment seat, a ...
