AI Technical Summary
Existing detachable electric laparoscopic staplers make it difficult to determine whether the gun barrel is properly installed during installation, which may lead to damage to the device and injury to the patient if it is not properly installed.
A metal conductive sheet and conductive bumps are installed between the gun barrel and the anastomosis device body. A circuit board is formed to ensure that the gun barrel can be installed in place before firing can be started, thus preventing misoperation.
This design allows firing to be initiated only after the device is properly installed, preventing damage to the device and harm to the patient, and improving the safety and reliability of the operation.
