Anti-misfiring electric endoscope anastomat

Abstract

This invention relates to the field of electric laparoscopic staplers, specifically an electric laparoscopic stapler designed to prevent accidental firing. The stapler includes a stapler gun body and an auxiliary handle fixed to one side of the gun body. This invention utilizes a purely mechanical hydraulic transmission structure to prevent accidental firing. A closed hydraulic system consisting of a main hydraulic pipe, a positioning branch pipe, and a collecting pipe, along with symmetrically arranged limiting blocks on both sides, enables independent bilateral detection of the staple cartridge installation status. This allows for simultaneous identification of insufficient axial insertion depth, lateral tilt, and forward / backward tilt installation deviations, eliminating blind spots present in existing technologies. The rigid locking mechanism between the positioning sleeve and the positioning block reliably locks the staple holder even when the staple cartridge is not fully in place, fundamentally eliminating the risk of accidental firing. This structure is completely independent of electronic components, unaffected by the complex electromagnetic environment of the operating room, and features an automatic reset function, allowing for repeated staple cartridge checks. Operation is simple and reliability is significantly improved.
