摘要： An arthroscopic cutting probe includes an outer sleeve having a longitudinal bore and an outer cutting window at its distal end. An inner sleeve is rotationally disposed in a bore of the outer sleeve, and the inner sleeve has a distal end, a proximal end, a longitudinal passageway, and an inner cutting window at its distal. An active electrode sleeve is disposed on an outer surface of the inner sleeve in a position opposed to the inner cutting window. Rotation of the inner sleeve relative to the outer sleeve causes the inner cutting window to rotate past the outer cutting window to resect tissue received through the cutting windows as they pass each other. Radiofrequency current can be applied to the active electrode to enhance tissue cutting then the cutting windows are being rotated or to able or cauterize tissue when the cutting windows are held stationary with the active electrode disposed through the outer cutting window.

摘要： A fluid management system includes a pump connectable to a fluid source. An inflow line removably connects to a cannula for delivering a fluid flow from the pump into a surgical site, such as a joint cavity. A flow pressure sensor is coupled to measure flow pressure in the inflow line and produce a measured pressure value, A controller is connected to the pump and the flow pressure sensor, and the controller maintains a pressure set point by controlling a pump speed based on a backpressure-adjusted pressure value calculated by subtracting a backpressure value selected from a backpressure table from the measured pressure value. The BAPV is monitored to determine whether the BAPV deviates outside an initial BAPV range, and corrective measure are taken should such deviations occur.

摘要： A resecting probe includes a shaft assembly having an outer sleeve and an inner sleeve. The outer sleeve has an axial bore and an outer window in a distal side thereof, and the inner sleeve has an axial extraction channel and inner window in a distal side thereof. The inner sleeve is rotationally disposed in the axial bore of the outer sleeve to allow the inner sleeve window to be rotated in and out of alignment with the outer sleeve window, and the shaft assembly forms a flow aperture in a distal portion when the inner cutting window and the outer cutting window are out of alignment. An electrode is carried on the inner sleeve, and a motor drive is coupled to rotate the inner sleeve relative to the outer sleeve. A controller is coupled to the motor drive and controls rotation of the inner sleeve and can stop rotation of the inner sleeve in a stop position where the outer and inner windows are out of alignment, providing the flow aperture to allow cooling of fluid in a working space and cooling of the probe handpiece during use.

摘要： A probe for ablating tissue comprises an electrosurgical working end configured to provide a first plasma about a first surface location and a second plasma about a second surface location, the first plasma having first ablation parameters and the second plasma having second ablation parameters. The probe has a working end with a thickness below 3 mm and produces a low temperature plasma.

摘要： An arthroscopic cutter according to one embodiment of the present disclosure includes an elongated outer sleeve that extends about a longitudinal axis with an interior bore having an open distal end. An inner sleeve is rotatable in the interior bore in the outer sleeve. The inner sleeve carries a distal housing having a longitudinal metal member and a longitudinal ceramic member that respectively form longitudinal-extending sides of the housing around an inner channel that communicates with a negative pressure source. The arthroscopic cutter also includes an electrode that is disposed in an outer surface of the longitudinal ceramic member.

摘要： A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A ceramic cutting member includes both a cutting window having sharp edges and one or more flutes with cutting burrs circumferentially spaced-apart from the cutting window. An electrode may be placed between a pair of flutes and opposite to the cutting window. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the ceramic cutting member cut bone with the flute(s) and soft tissue with the cutting window. The electrode provides cautery or radiofrequency ablation of tissue when the sleeve and ceramic cutting member are not being rotated.

摘要： An arthroscopic tissue resecting probe includes an elongated shaft having outer and inner sleeves which are formed from an electrically conductive material extending about an axis to a working end. Outer and inner resecting windows are formed in the sleeves in the working end. The working end includes a ceramic body having a collar portion extending fully around a region of the outer sleeve proximal to outer resecting window. A radiofrequency (RF) electrode is disposed on an outer surface of the ceramic body and is spaced-apart from the outer resecting window.

摘要： An arthroscopic or other medical device includes an elongate shaft having a proximal end and a working end. At least one electrode for treating tissue is located at the working end of the shaft, and a fluid outflow path extends proximally from the working end through a first channel portion in the shaft. A handpiece is coupled to the proximal end of the shaft and has a body with a second channel portion formed along an axis therein. The second channel is receives a heated or other outflow from a proximal end of the first channel in the shaft, and the second channel runs along an axis of the handpiece. A thin wall sleeve is located in the handpiece so that it surrounds at least a portion of the second channel. The thin wall sleeve is surrounded by an air gap or otherwise provides a thermal barrier between an exterior surface of the thin wall sleeve and an inner surface of the body of the handpiece in order to limit heat transfer from the heated or other fluid outflow through the second channel.

摘要： An arthroscopic device is used with a hand piece having a motor drive with a rotating drive shaft. An elongate probe extending along a longitudinal axis and includes a proximal hub on a proximal end. The proximal hub detachably couples to the hand piece, and an openable-closeable jaw structure is disposed on a distal end of the elongate probe. A conversion mechanism carried by the hub converts a rotational motion of the motor drive shaft to a longitudinal motion of an actuator member. The actuator member drives the jaw structure between jaw-open and jaw-closed positions to resect bone and other hard tissues.
