An improved multifunction cable for use in an operating room avoids the usual tangle of wires and tubes can be a significant hazard. The cable comes pre-sterilized with a number of wires and tubes pre-installed in a protective housing making it easy to conduct myriad wires and tubes from one region of the operating room to another without any possibility of tangling or violation of sterility. At the sterile end of the cable a special terminus acts as a holder to keep the various operating instrument organized. The terminus is designed to accept a special smoke evacuating monopolar electrosurgery instrument.

An electrosurgical wand is provided and includes a handle and an elongate shaft coupled to the handle and extending distally from the handle along an axis. An active electrode is disposed at a distal end of the electrosurgical wand. A return electrode abuts the elongate shaft and extends along and annularly about the axis. The return electrode has a top side adjacent the active electrode and an opposite bottom side and defines a notch. A support member is disposed in the notch between the electrodes and transitions curvilinearly from the notch to define a front surface extending laterally across and axially from the return electrode. The front surface tapers downwardly from the active electrode to define a first portion defining a first convex outer surface and also extends toward the bottom side of the return electrode to define a second portion defining a second convex outer surface.

An endoscope system is provided, which comprises an endoscope having a hollow tube formed therein, a flexible elongate member having a first end for operational control and a second distal end for operation of robotic members, one or more actuators coupleable to the flexible elongate member at the first end thereof, and an anti-buckling tube arranged with respect to the hollow tube at the first end of the endoscope to prevent buckling of the flexible elongate member during translation of the one or more actuators. Different embodiments are also disclosed, including an endoscope comprising one or more flexible tendons having a wire coil sheath which includes wire having a substantially rectangular cross section, or an endoscope comprising a rotational-motion transmitting device, one or more flexible tendons and one or more electrical wires having anti-kink support thereon, a coupling means constraining the robotic member to an asymmetric range of motion, or torque joint means comprising a centrally aligned pulley for coupling the robotic member.

An arthroscopic system includes a hand piece with a motor drive. an elongate shaft assembly is detachably secured to a distal end of the hand piece, and the elongate shaft assembly includes an outer sleeve and an inner sleeve rotatably mounted in the outer sleeve. The inner sleeve couples to the motor drive when the elongate shaft assembly is attached to the hand piece, and an inner distal cutting window on the inner sleeve moves in and out of alignment with an outer distal cutting window on the outer sleeve as the motor drive rotates the inner sleeve. A distal electrode is disposed on an outer surface of the outer sleeve at a location opposite to that of the outer distal cutting window, and the outer sleeve member is rotatable relative to the hand piece when the hub is secured to the hand piece such that a user can hold the hand piece in one hand and rotate the outer sleeve to selectively place the outer distal cutting window or the distal electrode in an upward orientation relative to the user while continuing to hold the hand piece in the one hand.

Disclosed is a surgical instrument with a handle and elongate shaft assembly extending distally from the handle. The elongate shaft assembly has a longitudinal axis and is able to articulate between a fully flexed configuration and a lesser flexed configuration. The elongated shaft assembly includes a first tubular member having a first flexible portion with a first preferential bending direction. The elongated shaft assembly also includes a second member including a second flexible portion axially fixed to the first tubular member at a position distal from the first flexible portion. The first flexible portion is defined by a plurality of cutouts, each cutout defining a cutout longitudinal axis transverse the shaft longitudinal axis and wherein the plurality of radial cutouts have an asymmetrical shape about the cutout longitudinal axis.

The cannula can have a connector configured to be electrically connected to a source of electrical power; a tip comprising: a printed circuit board (PCB); a first LED operatively connected and attached to the PCB and configured to emit light in a first wavelength range; and a shell configured to allow the light in the first wavelength range to pass from the first LED outside of the shell; and a middle section located between the connector and the tip, the middle section comprising: a hollow tube attached to the shell, the tube having apertures for collecting a liquid fat into the tube.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.

A surgical instrument includes a housing having a first handle and an elongated shaft extending therefrom. An end effector is disposed at a distal end of the elongated shaft and includes first and second jaw members, the first jaw member including a staple cartridge configured to house a series of staples therein. A second handle is operably coupled to the housing and is selectively moveable relative to the first handle to actuate the first and second jaw members between an open position and a closed position for grasping tissue. A first switch is activatable to supply energy to one of the jaw members. A stapler mode switch is actuatable between an unactuated position wherein movement of the second handle moves the jaws to the second position and an actuated position wherein movement of the second handle moves the jaws to the second position and drives the staples through tissue.

Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can include a catheter having a distal portion configured to be positioned adjacent to a thrombus in a blood vessel, an electrode disposed at the distal portion of the catheter, and an interventional element configured to be delivered through a lumen of the catheter. The electrode and the interventional element are each configured to be electrically coupled to an extracorporeal current generator. Delivery of current to the interventional element can be gradually ramped up during initialization to improve patient comfort and safety.
