Motor-driven ring-cutting anastomat

Abstract

The invention discloses a motor-driven ring-cutting anastomat which comprises a meshing cutting mechanism and a driving execution mechanism. The driving execution mechanism comprises a tube body, a transmission screw tube fixedly arranged at the back end in the tube body, a push tube, a center rod, a motor and a clutch. Threads are formed on the inner wall face and the outer wall face of the transmission screw tube. The push tube is arranged in the tube body, the front end of the tube body is connected with a nail pushing assembly of the meshing cutting mechanism in transmission mode, and the back end of the nail pushing assembly is connected with outer threads of the transmission screw tube in meshing mode. The center rod is arranged in the push tube, the front end of the center rod is in transmission connection with a nail abutting seat, and the back end of the center rod is connected with the inner threads of the transmission screw tube in meshing mode. The motor is fixedly arranged in a power cavity fixedly connected with the tail portion of the tube body. The clutch is capable of transferring output of the motor to the center rod or the push tube. The motor-driven ring-cutting anastomat is simple in structure, high in practicability and capable of achieving adjustment and percussion by only one motor, reduces processing cost, is convenient to control, improves using effect, utilizes the motor for percussion and avoids difference caused by manual percussion.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to an electric circumcision kisser. Background technique [0002] The medical stapler is a medical device that is often used in the surgical operation of the physiological tissues of the digestive tract. The commonly used staplers are all manual operations in the process of "closing, anastomosing, and cutting" the physiological tissues, usually manual steps It is cumbersome and prone to misoperation or failure of the operation. In addition, due to individual differences, the degree of closure of the tissues and the closure time are prone to be inconsistent during manual closure operations, and the firing force during firing operations will vary greatly, thereby reducing the quality of the operation. [0003] In order to overcome the shortcomings of manual operation, Chinese patent 201110109722.7 discloses a kisser, which includes a kiss-cutting part with a nail seat, a sta...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned two driving motors and two transmission mechanisms are complicated and difficult to operate. When the kiss cut needs to be fired, two buttons need to be pressed at the same time, which is easy to cause linkage or interference, and the safety control device is manual. Two sets of The drive motor will increase the size and cost, which is not conducive to marketization
