Abstract

The invention relates to an anastomat, which comprises a body, a pin bin which is arranged on the body, a pin pushing plate which is arranged inside the pin bin, and a push rod which is arranged on the body and used for pushing the pin pushing plate, wherein the front end of the push rod is provided with a push part which contacts the pin pushing plate; the lower end face of the push part is flush with the lower end face of the pin pushing plate; and a limit stop is pressed below the pin pushing plate and connected with a reset mechanism which drives the limit stop to upspring. After the suturing process is over each time, the push rod can be retracted, the pin pushing plate is rested on the front of the pin bin, and the limit stop upsprings under the action of the reset mechanism and prevents the push rod from pushing the pin pushing plate to suture again, so that the anastomat has the function of locking the hollow pin bin and surgical failure can not be caused due to reutilization of the hollow pin bin.

Description

technical field [0001] The invention relates to a stapler for surgery. Background technique [0002] Staplers are widely used in low rectal resection surgery, which makes the operation safer. There is no empty staple cartridge locking device in the general stapler, and there is no staple in the staple cartridge after suturing, which may be operated due to negligence, so that the operation fails and unnecessary accidents are caused. Contents of the invention [0003] The purpose of the present invention is to provide a stapler. When the staple cartridge is empty, the instrument is locked and cannot be operated. [0004] In order to achieve above object, the scheme that the present invention adopts is: [0005] A stapler, comprising a body, a staple cartridge arranged on the body, a nail pusher disposed inside the staple cartridge, a push rod disposed on the body for pushing the staple pusher, the The front end of the push rod has a pushing part in contact with the nail p...
