Abstract: An end effector assembly for use with a forceps includes a pair of jaw members, a knife assembly, and one or more cam assemblies. One or more of the jaw members are moveable relative to the other about a pivot between open and closed positions. One or more of the jaw members include a knife channel. The pivot includes first and second sections defining a passage therebetween. The knife assembly includes a knife blade and an actuation shaft. The knife blade is disposed distally relative to the pivot. The actuation shaft is configured for slidable translation through the passage to allow selective advancement of the knife blade through the knife channel. The one or more cam assemblies are operably coupled to the one or more moveable jaw members and are actuatable to move the one or more jaw members between the open and closed positions for grasping tissue therebetween.

Abstract: A system and method for using a remote control to control an electrosurgical instrument, where the remote control includes at least one momentum sensor. As the surgeon rotates their hand mimicking movements of a handheld electrosurgical instrument, the movements are translated and sent to the remote controlled (RC) electrosurgical instrument. The surgeon uses an augmented reality (AR) vision system to assist the surgeon in viewing the surgical site. Additionally, the surgeon can teach other doctors how to perform the surgery by sending haptic feedback to slave controllers. Also, the surgeon can transfer control back and forth between the master and slave controller to allow a learning surgeon to perform the surgery, but still allow the surgeon to gain control of the surgery whenever needed. Also, the surgeon could be located at a remote location and perform the surgery with the assistance of the AR vision system.

Abstract: A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

An end effector extending from the elongated shaft is in communication with a source of electrosurgical energy and defines an end effector axis. A roll joint couples the end effector to the elongated shaft and includes a first tubular structure extending distally from the elongated shaft and a second tubular structure rotatably coupled to the first tubular structure. The second tubular structure supports the end effector such that the end effector is rotatable about the end effector axis.

Abstract: A surgical instrument includes an elongated shaft having a proximal structural member and a proximal drive member that is selectively movable with respect to the proximal structural member. A modular end effector is removably coupled to the elongated shaft, and has a distal structural member and a distal drive member that is operatively coupled to a pair of jaw members. A separable joint is defined between the elongated shaft and the end effector. The separable joint includes laterally prominent and laterally indented portions of each of the proximal and distal structural members and of each of the proximal and distal drive members. The structural members are interlocked to resist longitudinal separation and permit lateral separation. The drive members are movable relative to structural members to move the separable joint to a locked configuration wherein the drive members prohibit lateral separation of the structural members.
