A dual-power intracavitary cutting stapler

Abstract

The present invention discloses a dual-power intracavitary cutting stapler, wherein a rack connecting block is slidably connected to the distal end of a driving rack, the rack connecting block can slide relatively to the rack within a certain range, and the driving rack can push the rack connecting block to move synchronously; the distal end of the rack connecting block is detachably connected to a push rod, the distal end of the push rod can be connected to a cutting assembly, and the rack connecting block moves synchronously with the push rod; a manual closing handle is rotatably connected to a body through a handle connecting shaft, the manual closing handle can rotate relative to the body, and when the manual closing handle rotates, the rack connecting block can be driven to move relative to the driving rack; when in use, an operator manipulates the manual closing handle to make the rack connecting block move independently relative to the driving rack, and closes and opens the jaws by gripping and pushing the manual closing handle, and the closing force is directly fed back to the manual closing handle to provide tactile feedback, thereby providing guidance for the appropriate selection of the cutting assembly.
