Anastomat

Abstract

The invention relates to an anastomat, which comprises a body, a pin bin which is arranged on the body, a cutting knife which is arranged inside the pin bin, and a connecting rod which is arranged on the body and used for pushing the cutting knife to move, wherein a cutting wrench is rotationally connected to the body; a pushing block is arranged on the cutting wrench; a groove is arranged on a connecting rod; and the pushing block is matched with the groove and is at least provided with two operating states, wherein the pushing block is disengaged from the groove in the first operating state, and is positioned inside the groove and leans against the side wall of the groove in the second operating state. Due to adoption of the cutting wrench to operate the cutting knife, large force moment can be exerted on the cutting wrench only with small force, so that the cutting wrench can provide large thrust force to the connecting rod and then push the cutting knife to cut, thereby the cutting operation is more labor-saving; during the cutting process, people only need to rotate the cutting wrench to a certain angle, so that the operation is more convenient; and when the cutting process is not over, the cutting knife can not be operated for cutting even when the cutting wrench is pulled, so that the anastomat has safety function.

Description

technical field [0001] The present invention relates to a surgical stapler. Background technique [0002] Staplers are widely used in anterior low rectal resection to make the operation safer. In the utility model CN2759397 (authorized announcement date is February 22, 2006), a stapler is disclosed. The stapler is provided with a positioning needle that can slide along the body, and the front end of the positioning needle is fixedly connected with the cutting knife. The rear end of the needle is provided with a push-torque, and the push-torque must be given a forward thrust when cutting, and the cutting knife is pushed through the positioning needle for cutting, which requires a large force and is inconvenient to operate; Accidentally operating the push and twist, it will push the cutter to cut, causing the operation to fail. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a stapler, which is more labor-saving during cutting, more con...
