ELECTROSURGICAL END EFFECTOR WITH INDEPENDENT CLOSURE FEATURE AND BLADE

摘要

An apparatus includes a body, an end effector, and outer beam, and an inner beam. The body comprises an actuator. The end effector is in communication with the body and has a first jaw and a second jaw. The outer beam is able to advance within the end effector such that the outer beam closes the second jaw toward the first jaw. The advancement of the outer beam is controlled mainly by the actuator. The inner beam is also able to advance within the end effector such that the inner beam transects tissue. The actuator is operable to control the advancement of the inner beam in at least two stages. The actuator advances the inner beam and the outer beam together in a first state. The actuator advances the inner beam while the outer beam remains stationary in a second stage.

主权项

1. An apparatus for operating on tissue, the apparatus comprising:
(a) a body comprising an actuator; (b) an end effector in communication with the body, wherein the end effector comprises a first jaw and a second jaw configured to clamp tissue; (c) an outer beam configured to advance within the end effector, wherein the outer beam is configured to close the second jaw toward the first jaw, wherein the actuator is configured to advance the outer beam within the end effector; and (d) an inner beam configured to advance within the end effector, wherein the inner beam is configured to transect tissue, wherein the actuator is configured to control the advancement of the inner beam in at least two stages, wherein the actuator is configured to advance the inner beam and the outer beam together in a first stage, wherein the actuator is configured to advance the inner beam while the outer beam remains stationary in a second stage.
