FIRING AND SWITCHING MECHANISM AND MEDICAL STAPLER

WIPO Patent Application WO/2024/017223

A1

A firing and switching mechanism and a medical stapler. The firing and switching mechanism comprises: an actuating rod; a switching member (7), which comprises a stop portion (71), the switching member (7) being able to move from a first position to a second position in the axial direction; a firing member, which can be driven to move from a first state away from the actuating rod to a second state close to a driving portion; when the switching member (7) is in the first position and the firing member is driven to enter into the second state from the first state, the firing member abuts against the stop portion (71), and the firing member does not drive the actuating rod. and when the switching member (7) is in the second position and the firing member is driven to enter into the second state from the first state, the firing member drives the actuating rod to move in the direction of a distal end side. By means of utilizing the present apparatus, when the switching member (7) is in the first state, a firing portion is incapable of firing the stapler, and accidental firing when not in a firable state is prevented.
