Abstract

The invention discloses an intracavity incision anastomat. The intracavity incision anastomat comprises a fixed handle, a closed handle and a jaw opening and closing transmission mechanism which is connected with the closed handle. The closed handle is used for opening and closing a jaw, the closed handle is further connected with a closed handle linkage part, and a locking area is arranged on the closed handle linkage part. The locking area can be locked with an unlocking switch which is fixed on the fixed handle. The fixed handle is provided with a jaw closing safety device, and the unlocking switch can be limited by opening the jaw closing safety device. The locking area can not be locked with the unlocking switch when the jaw is closed, the jaw closing safety device is closed, and the locking area is locked with the unlocking switch when the jaw is closed. In the instrument original state, the jaw closing safety device is placed in the opened mode, closing and opening of the jaw can be operated freely, unlocking operation is needless, and using is convenient.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an intracavity cutting stapler with a jaw closing safety device. Background technique [0002] The endocavity cutting stapler is used in abdominal and endoscopic surgery, and it is often necessary to use the jaws of the stapler head to freely clamp or turn the tissue during use. When entering the puncture device, you need to hold the closing handle to close the jaws, and then open the jaws for operation after entering. However, in the current endovascular cutting stapler, the jaws are locked when they are closed, and they need to be unlocked when they are opened again. Only steps can be realized, and it is very troublesome to use. Contents of the invention [0003] The technical problem to be solved by the present invention is that it is inconvenient to open the jaws of the endocavity cutting stapler after they are closed. [0004] In order to solve the above-mentioned tech...
