A tissue sensing device for use with an electrosurgical knife is proposed which comprises a proximal end portion, a distal end portion and a grip portion there between. The proximal end portion is configured for attachment to a housing of the electrosurgical knife. The distal end portion is configured for movably supporting a blade of the knife. A distal end of an optical fiber is arranged at the distal end portion of the device and a proximal end of the optical fiber is connectable to an optical console, so that optical measurements can be performed at the distal end portion.

A surgical device including a handle assembly, an elongated portion, an end effector, a drive shaft, and a wick is disclosed. The wick is disposed within an outer sleeve of the elongated portion and is made from a fibrous material. The wick is configured to transfer moisture from a first portion of the wick to a second portion of the wick.

A forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. A knife assembly having a cutting blade disposed at a distal end thereof is also provided. The knife assembly is translatable relative to the end effector assembly between a retracted position and an extended position, wherein the cutting blade extends between the jaw members to cut tissue grasped therebetween. The knife assembly includes a proximal component and a first distal component that includes the cutting blade. The proximal and first distal components are removably coupled to one another to facilitate replacement of the first distal component. Methods of preparing such forceps for reuse are also provided.

Disclosed herein is a surgical navigation instrument having a temperature sensor. The surgical navigation instrument can easily perform an autoclave action to remove microorganisms using saturated steam with respect to a part which can be contaminated during treatment, and enhance convenience in replacement of a grip part and the electrodes of the handpiece which are consumables, since a handpiece and electrodes are detachably screw-coupled with each other.

An electrode assembly for use with an electrosurgical instrument includes a base portion, a return lead adapted to be electrically coupled to a return terminal of an electrosurgical generator, an electrical insulator supported on a distal portion of the return lead, a tensioning mechanism, and an active lead adapted to be electrically coupled to an active terminal of the electrosurgical generator. The tensioning mechanism includes a slider slidably disposed in the base portion, a rotation rod threadably coupled to the slider, and a spring proximally biasing the slider. The active lead having a first end portion securely fixed to the base portion and a second end portion slidably coupled to the rotation rod of the tensioning mechanism. A portion of the active lead extends around the electrical insulator. Rotation of the rotation rod causes axial displacement of the second end portion of the active lead to tension the active lead about the electrical insulator.

Methods and apparatuses are described herein for inactivation of bacterial biofilms using sub-microsecond pulsed electric field application to an affected surface or region. In some examples, a bacterial biofilm may be inactivated while planktonic bacteria in the vicinity of the biofilm are not inactivated. These methods and systems provide an electrical-based therapeutic modality for which bacteria in biofilms may have difficulty developing resistance, unlike antibiotic therapies.

Instruments having a hood that defines and surrounds a flow chamber. The flow chamber can serve for suction of emissions that are produced due to influence of an electrode supplied with high frequency voltage on biological tissue. For elimination of tissue deposition and other clogging from the flow chamber the electrode is surrounded by a movable hood that can be transitioned for cleaning purposes out of its operating position into a cleaning position.

A surgical cleaning tool and method of cleaning a surgical tool. The surgical cleaning tool includes a shaft, a handle and an end portion. The shaft has a distal end and a proximal end. The handle is attached to the distal end of the shaft The end portion is connected to the proximal end of the shaft, wherein the end portion has an outer surface, an inner cavity, an inner surface, at least one cleaning element connected to at least a portion of the inner surface, and an opening in a wall portion of the end portion, wherein the opening allows access to the cleaning element in the inner cavity of the end portion.

There is provided an energy device for surgical operation capable of suppressing fixation of body tissue, wherein a coating layer is formed on an outer periphery of a base material constituting an operational area portion transmitting energy in an energy device for surgical operation operating in the operational area portion, and is comprised of a base coating formed on the base material and an outermost coating formed on the base coating. The base coating is made from silicon oxide or a compound containing silicon oxide, and the outermost coating is made from polysiloxane or a compound containing polysiloxane or a compound containing a partly fluorinated polysiloxane, and the coating layer has a good adhesiveness and is applicable to a complicated form.

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.
