Problems solved by technology

[0002] At present, the disposable linear stapler lacks a firing safety mechanism, which is easy to cause false firing during use. In addition, the linear stapler is not equipped with a firing indicator device, and it is impossible to observe whether the staples are fired during use. The current linear stapler firing transmission The structure of the device is relatively complicated, and the use is not convenient enough to easily cause false firing, which affects the success rate of the operation, and is inconvenient to assemble

Abstract

The invention relates to a triggering safety mechanism of a disposable linear anastomat, which belongs to a matched triggering safety mechanism of the disposable linear anastomat. The disposable linear anastomat is particularly applicable to stump and cut sealing in alimentary tract and gastroenteritic operation. The triggering safety mechanism comprises a positioning rod, a fixed positioning rod slide block, a safety slide plate and a safety block, wherein slide grooves are arranged in the fixed positioning rod slide block, the positioning rod is arranged and inserted in a groove of the fixed positioning rod slide block, one end of the safety slide plate is arranged in a clamp groove at the lower part of the fixed positioning rod slide block, the other end of the safety slide plate is provided with the safety block, the safety block is arranged in the slide grooves of the safety block arranged at the front end of a fixed handle, the fixed positioning rod slide block is sheathed and arranged at the middle part of an upper clamp plate and a lower clamp plate of a nail propping seat through the slide grooves. The slide grooves of the safety block are two to three, and the slide grooves of the safety slide plate are arranged at the front end part of the fixed handle. Because the disposable linear anastomat is provided with the triggering safety mechanism, the error triggering in the operation process can be avoided.

Description

technical field [0001] The invention relates to a firing safety mechanism of a disposable linear stapler, which is a matching firing safety mechanism of a disposable linear stapler. The disposable linear stapler is especially suitable for sealing stumps and incision. Background technique [0002] At present, the disposable linear stapler lacks a firing safety mechanism, which is easy to cause false firing during use. In addition, the linear stapler is not equipped with a firing indicator device, and it is impossible to observe whether the staples are fired during use. The current linear stapler firing transmission The structure of the device is relatively complicated, and the use is not convenient enough to easily cause false firing, which affects the success rate of the operation, and is inconvenient to assemble. Contents of the invention [0003] The purpose of the present invention is to provide a firing safety mechanism for a disposable linear stapler aimed at the abo...
