  • Patent number: 11653972
    Abstract: Tissue is resected and extracted from an interior location in a patient's body using a probe or tool which both effects resection and causes vaporization of a liquid or other fluid to propel the resected tissue through an extraction lumen of the resecting device. Resection is achieved using an electrosurgical electrode assembly including a first electrode on a resecting member and a second electrode within a resection probe or tool. Over a first resecting portion, radio frequency current helps resect the tissue and over a second or over transition region, the RF current initiates vaporization of the fluid or other liquid to propel the tissue from the resection device. In one embodiment, an extending element extends from a housing and into a channel in a resecting member as the resecting member moves toward a distal position.

The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis of the shaft. The articulation drive assembly comprises an actuator. The actuator is movable relative to the body assembly to drive articulation of the articulation section. The locking feature is in communication with the actuator. The locking feature is movable between an unlocked state and a locked state. The locking feature is configured to permit movement of the actuator relative to the body assembly in the unlocked state. The locking feature is configured to prevent movement of the actuator relative to the body assembly in the locked state.

  • Patent number: 11207127
    Abstract: A surgical end effector assembly includes a pair of jaw members, a knife defining a longitudinal slot, a pivot pin coupling the jaw members to one another, and a drive member including a drive pin that is engaged to the jaw members. The pivot pin and/or the drive pin extends through the longitudinal slot of the knife to couple the knife to the jaw members and/or the drive member. The end effector assembly is transitionable between a use position, wherein the knife and drive member are generally aligned with one another to facilitate releasable engagement of the end effector assembly with a surgical instrument, and a cleaning position, wherein the jaw members, knife, and drive member are fanned apart from one another to facilitate cleaning of the end effector assembly. Methods of disengaging and sterilizing end effector assemblies for reuse are also provided.

  • Patent number: 11160620
    Abstract: End effectors for driving tools at surgical sites along trajectories maintained by surgical robots. A tool has interface and working ends. An end effector has a mount to attach to the surgical robot, and an actuator configured to generate torque. A drive assembly with a geartrain translates rotation from the actuator into rotation of a drive conduit supported about an axis. A rotational lock operatively attached to the drive conduit releasably secures the tool for concurrent rotation about the axis, and an axial lock releasably secures the tool for concurrent translation with the drive conduit along the trajectory maintained by the surgical robot. The axial lock is operable between a release configuration where relative movement between the drive assembly and the tool is permitted along the axis, and a lock configuration where relative movement between the drive assembly and the tool is restricted along the axis.
