Surgical device and handle assembly for use therewith

摘要

A surgical instrument is disclosed. A rotation mechanism is disposed in mechanical cooperation with a handle assembly and effects rotation of an end effector. The rotation mechanism includes a first member including at least one magnet, and a second member including at least one magnet. The first member and the second member define a space therebetween. The articulation mechanism is disposed in mechanical cooperation with the handle assembly and effects articulation of the end effector. The articulation mechanism includes a plurality of tendons. Each tendon extends longitudinally through the space between the first member and the second member of the rotation mechanism.

主权项

1. A surgical instrument, comprising;
a handle assembly including a housing and a movable handle that is configured to be engaged by a user; an elongated shaft extending distally from the handle assembly and defining a first longitudinal axis; an end effector disposed in mechanical cooperation with a distal portion of the elongated shaft, the end effector defining a second longitudinal axis, the end effector includes jaw members that are movable between an open position and an approximated position; and an actuation rod disposed in mechanical cooperation with the handle assembly and with the end effector, the actuation rod configured for longitudinal translation with respect to the handle portion; wherein the movable handle is movable between a first position where the jaw members of the end effector are in an open position and a second position where the jaw members are in an approximated position, wherein the movable handle is disposed substantially parallel to the first longitudinal axis when the movable handle is in one of the first position, the second position or any position therebetween, wherein at least a majority of the movable handle is disposed on a first side of the first longitudinal axis when the movable handle is in one of the first position, the second position or any position therebetween, a proximal portion of the movable handle is pivotally attached to a proximal portion of a proximal link, a distal portion of the proximal link is pivotally attached to a proximal portion of a distal link via a first pin, the first pin being movable towards and away from the first longitudinal axis, wherein the first pin is disposed on a second side of the first longitudinal axis when the movable handle is in the first position, and a distal portion of the distal link being pivotably connected to the housing via a second pin.
