摘要： 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.

摘要： 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.

摘要： An end-effector assembly includes opposing first and second jaw members, at least one of which is movable relative to the other from a first position wherein the jaw members are disposed in spaced relation relative to one another to at least a second position closer to one another wherein the jaw members cooperate to grasp tissue therebetween. Each jaw member includes an electrically-conductive, tissue-engaging structure extending along a length thereof. Each electrically-conductive, tissue-engaging structure is configured to connect to a source of electrosurgical energy for conducting electrosurgical energy through tissue grasped between the opposing first and second jaw members to effect a tissue seal. The end-effector assembly includes a split electrode including a first electrode portion and a second electrode portion spaced apart from the first electrode portion and electrically-isolated therefrom by a gap defined therebetween. The first and second electrode portions are associated with one of the electrically-conductive tissue-engaging structures.

摘要： The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.

摘要： An end effector assembly for use with an instrument for sealing and cutting tissue includes a pair of opposing first and second jaw members movable relative to the to grasp tissue therebetween. Each jaw member including a jaw housing and an electrically conductive surface adapted to connect to a source of electrosurgical energy such that the electrically conductive surfaces are capable of conducting electrosurgical energy through tissue held therebetween to effect a tissue seal. One of the electrically conductive surfaces including a channel defined therein and extending along a length thereof that communicates with a nozzle disposed in the jaw housing. The nozzle is configured to direct high pressure fluid from a fluid source into the channel for cutting tissue grasped between the jaw members.

摘要： A surgical instrument includes a housing having an elongated shaft extending distally therefrom. An end effector for treating tissue is supported by the elongated shaft. One or more tensile members extend at least partially through the elongated shaft. A proximal end of a tensile member is operatively coupled to at least one actuator and a distal end is operatively coupled to the end effector such that manipulation of the actuator induces movement of the tensile member to move the end effector. A de-tensioning mechanism is operatively associated with the tensile member to move the tensile member between a first relaxed configuration and a second stressed configuration. The de-tensioning mechanism includes a spacer insertable into a cavity defined in the housing to move the tensile member to the first relaxed configuration and removable from the cavity to move the at least one tensile member to the second stressed configuration.

摘要： An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.
