Problems solved by technology

[0002] When the movable handle in the tubular anastomat is fired, it drives the curved push rod to move forward to push the anastomotic cutting component to move. When the existing tubular anastomat is in use, it is difficult for the movable handle to be completely fixed at a certain position in the middle after firing. Stopping, slipping and other phenomena are prone to occur and cause anastomosis failure. At the same time, in order to ensure the integrity of each firing, it is required that the movable handle can be reset after firing in place, and the existing stapler structure is difficult to control this point.

Abstract

The invention discloses a tubular anastomat with a non-return function. The tubular anastomat comprises a fixed handle and a mobile handle, wherein a bent push rod which is pushed and started by the mobile handle is arranged in the fixed handle; racks are arranged at the back of the tail end of the bent push rod; a stop block is arranged on one side, corresponding rack surfaces, of the racks; the end part of the stop block is coordinated with the racks in a clamping manner along with the moving of the bent push rod, so that, after being triggered, the mobile handle can be stopped at any position. According to the tubular anastomat, a row of racks are additionally arranged at the tail end of the bent push rod, by using the meshing blocking of the stop block and the racks during a moving process, the mobile handle can be stopped at any time when the mobile handle is triggered to one position, so that mesh failure caused by phenomenon of slipping and the like is prevented, the mobile handle is enabled to be reset after reaching to the end, and the completeness of each triggering is ensured.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tubular stapler with a non-reverse function. Background technique [0002] When the movable handle in the tubular anastomat is fired, it drives the curved push rod to move forward to push the anastomotic cutting component to move. When the existing tubular anastomat is in use, it is difficult for the movable handle to be completely fixed at a certain position in the middle after firing. If it is stopped, it is easy to cause slipping and other phenomena and cause anastomotic failure. At the same time, in order to ensure the integrity of each firing, it is required that the movable handle can be reset after firing in place, and the existing stapler structure is difficult to control this point. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a tubular stapler w...
