11576715 · 2023-02-14 · ·

A surgical instrument comprises a handle assembly including an actuator mounted for manipulation through an actuation stroke. An elongate shaft extends distally from the handle assembly and defines a longitudinal axis. A reciprocating member extends at least partially through the elongate shaft, and is mounted for longitudinal motion through the elongate shaft in response to manipulation of the actuator through the actuation stroke. A drive mechanism includes a first rotating component coupled to the actuator about a first circumference to induce rotational motion in the first rotating component. A second rotating component is coupled to the first rotating component such that rotational motion in the first rotating component induces rotational motion in the second rotating component. The second rotating component is coupled to the reciprocating member about a second circumference such that rotational motion of the second rotating component induces longitudinal motion in the reciprocating member. The second circumference is greater than the first circumference.

A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.
