Abstract
An actuation mechanism for a surgical instrument (100) includes a sleeve (202) configured to receive the surgical instrument and including one or more parts (208, 210, 226), with studs (250, 252) provided on each part, on some parts only, or distributed over the different parts. At least two wheels (204, 206) are mounted on the sleeve on either side of the part or parts, each wheel being equipped with at least one groove (242) and a mechanical transmission element (244). The groove of each wheel movably receives one of the studs in the groove. At least two drive shafts (212, 214), each being equipped with a first mechanical transmission element (254), cooperate with the mechanical transmission element (244) of one of the wheels.
