A two-speed adjusting device for a digestive tract stapler includes a stapler body,Intraluminal Stapler a knob body rotatably connected with the stapler body,Intraluminal Stapler and a screw threadedly connected with the knob body,Intraluminal Stapler the screw is inserted in the anastomosis In the inner cavity of the body, the front part of the screw is connected with the central rod in the inner cavity of the body of the stapler. The screw has a first thread segment and a second thread segment connected. The pitch is greater than the pitch of the second thread segment.Intraluminal Stapler The distance between the nail cartridge and the nail holder can be quickly shortened, and the second thread segment slides relative to the knob body after being shortened,Intraluminal Stapler so that the moving speed of the screw becomes slow when the knob is turned, which is beneficial to the operation of the digestive tract.
