US Patent 11648051 Surgical instrument

A surgical instrument includes a jaw tool with two branches that can be closed for grasping tissue. In order to transmit the closing force to at least one branch, the branch is coupled with a preferably manually actuatable pull/push element, and, for coupling, an actuating pin that supports a sleeve interacts via the sleeve with a coupling track, in which case the sleeve rolls off the coupling track. In this manner, any deformation, abrasion or burr formation on the coupling track is prevented to such an extent that, even after numerous closing movements of the branches, the branches can still be actuated unimpaired by any wear of the coupling track and the actuating pin, respectively.
