A surgical instrument system includes a surgical instrument, a power supply, and an accessory. The surgical instrument has a first induction device positioned therein. The power supply is electrically coupled to the first induction device. The accessory is selectively operably couplable to the surgical instrument. The accessory includes a second induction device that is inductively coupled with the first induction device when the accessory is operably coupled to the surgical instrument such that the power supply provides power to the accessory.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

The present invention is directed to an endoscopic implant cutting and/or fragmenting apparatus of the bipolar type, operating on direct current, comprising an endoscope instrument having at least two opposing electrodes at its distal instrument head forming a cutting gap inbetween for receiving an electrically conductive implant or implant section to generate punctiform physical contact with the implant, and a DC-impulse generator having or connected to a control device adapted to generate a direct current in a pulsed way being controlled by the control device such that in a first phase of physical contact, the current pulse is adjusted preferably by controlling the current value at the electrodes to induce electric energy into the implant material being sufficient to melt the implant material exclusively in the area of the contact portion and in a second phase of physical noncontact, the current pulse is adjusted preferably by controlling the voltage value at the electrodes to generate an electric arc between at least one electrode and the melted implant material being sufficient to cut the melted implant material.

A surgical instrument includes: a clamp section main body which is movable between a close position that is close to a vibration transmission member and an away position that is away from the vibration transmission member; a pressure pad provided on the clamp section main body and provided on a position that is close to the vibration transmission member, the pressure pad being brought into contact with the vibration transmission member when the clamp section main body is in the close position; and a pressing member which is configured to press the vibration transmission member in association with the clamp section main body coming close to the close position, and is configured to decrease pressure of contact between the pressure pad and the vibration transmission member.

Various exemplary methods, systems, and devices for initializing a surgical tool are provided. In general, a surgical tool can include an end effector, an elongate shaft, and a wrist that couples the end effector to a distal end of the shaft. The wrist can be configured to facilitate movement of the end effector relative to the shaft. The surgical tool can include multiple flexible members configured to move, either individually or as a group including any plural number of the flexible members, to cause the movement of the end effector relative to the shaft by pivoting at the wrist. The movement of the end effector can include movement between an unarticulated position and an articulated position. The surgical tool can also include one or more homing members configured to be selectively actuated to force the end effector into the unarticulated position.

A surgical instrument includes a female branch defining in a coupling area a hollow volume including inwardly facing inner coupling surfaces and including a male branch which can be pivoted relative to the female branch at least partly inside the hollow volume about a pivot axis, the male branch defining in the coupling area a guide portion having outwardly facing outer coupling surfaces in which outer coupling recesses are arranged, wherein on the inner coupling surfaces, inner coupling recesses are arranged which extend relative to a longitudinal axis of the surgical instrument in a direction other than that of the outer coupling recesses.

A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.

An electrode assembly for use with an electrosurgical instrument includes a pair of opposing jaw members and an electrode positioned on each jaw member. One or both of the electrodes includes a tissue contacting surface that has an outer periphery and defines a side surface depending therefrom. The tissue contacting surface and the side surface include a conjoining edge formed at a first predetermined angle that defines a first linear transition zone dimensioned to reduce arcing between the opposing jaw members during activation of the electrosurgical instrument.

The embodiments disclosed herein relate to various medical device components, including components that can be incorporated into robotic and/or in vivo medical devices, and more specifically including end effectors that can be incorporated into such devices. Certain end effector embodiments include various vessel cautery devices that have rotational movement as well as cautery and cutting functions while maintaining a relatively compact structure. Other end effector embodiments include various end effector devices that have more than one end effector.

A surgical instrument includes a housing, an energizable member, and a deployment mechanism. The energizable member is movable relative to the housing between a storage position and a deployed position. The deployment mechanism includes a first actuator member movable relative to the housing from a first un-actuated position to a first actuated position to move the energizable member from the storage position to the deployed position and a second actuator member movable relative to the housing from a second un-actuated position to a second actuated position to move the energizable member from the deployed position to the storage position. Movement of the first actuator member from the first un-actuated position to the first actuated position effects movement of the second actuator member from the second actuated position to the second un-actuated position and vice versa.
