Abstract: A surgical device, such as a debrider, can include an elongated inner shaft that is movable within an elongated, hollow outer shaft. An actuator can controllably impart movement to a proximal portion of the inner shaft. A cutting element, located at a distal portion of the inner shaft, can move with the inner shaft. The outer shaft can expose the cutting element as the inner shaft moves. The inner shaft can include a flexible inner shaft portion. A plurality of bearings, located between the inner shaft and the outer shaft along the flexible inner shaft portion, can space the flexible inner shaft portion with respect to the outer shaft as the inner shaft moves. The plurality of bearings can help reduce friction between the inner shaft and the outer shaft and help maintain concentricity of the inner shaft and the outer shaft.

Abstract: Provided is a medical device comprising an inner tubular member, an outer tubular member having a distal end and an open window disposed at the distal end, a first electrode and/or a second electrode disposed at the distal end of the outer tubular member, and a cannulated plunger or armature or shaft configured to drive the inner tubular member to cut tissue in cooperation with the open window of the outer tubular member wherein the first electrode and the second electrode are configured to provide RF energy needed for surgical operation and wherein the first and the second electrodes may be configured to be symmetrical or substantially symmetrical along a longitudinal axis of the outer tubular member or wherein the first electrode is configured to cover the open window of the outer tubular member and extended to one side of the outer tubular member and the second electrode is configured to be disposed on the other side of the outer tubular member.

Abstract: Disclosed herein is a medical device. The medical device includes a blade tube section, a solenoid, and a mechanical arrangement. The blade tube section includes an outer blade tube, an inner blade tube, and a cutting window at a distal end of the blade tube section. The solenoid is offset from a central axis of the blade tube section. The mechanical arrangement is between the inner blade tube and the solenoid.

Abstract: A cutting instrument comprising: an outer tube comprising a distal end and a proximal end; an inner tube rotatably disposed within said outer tube, said inner tube comprising a distal end, a proximal end and a region intermediate said distal end and said proximal end, said region comprising a plurality of slits formed in said inner tube so as to render said region of said inner tube flexible; and a bellows disposed adjacent to said plurality of slits so as to render said region of said inner tube fluid-tight.

Abstract: A medical device includes a hollow tubular connector having a first open end and a second open end, the first open end configured to be connected to a suction port of a surgical cutting device, and the second open end configured to be connected to a source of pressurized air, the hollow tubular connector including a first seal located proximate the first open end and having a first diameter, the first seal being configured to sealingly accommodate a tubular shank, of a first diameter, of a blade of the surgical cutting device.

Abstract: A medical device is provided. The medical device can include an elongated shaft, an optical illumination carrier to provide light to a distal end of the shaft, an optical carrier to provide light incident on the distal end of the shaft to a proximal portion of the endoscope, and an attachment device mechanically coupled to the shaft such that the attachment device is rotatable about a perimeter of the shaft.

Abstract: A two-position handpiece coupling seal is provided. The two-position handpiece coupling seal includes a neck disposed at a first end that is configured to receive an implement. The two-position handpiece coupling seal has a first seal disposed about the neck of the two-position handpiece coupling seal. The first seal is configured to engage with a surface of a housing of a handpiece that uses the two-position coupling seal in a first position. The two-position handpiece coupling seal has a second seal disposed about a bore of the two-position handpiece coupling seal at a second end of the two-position handpiece coupling seal opposite the first end. The bore is configured to receive a driveshaft and the second seal is configured to sealingly engage with the driveshaft when the bore receives the driveshaft.

Abstract: A cutting accessory for use with a powered surgical tool includes an elongated outer tube with an outer hub attached to the proximal end for releasably securing the cutting accessory within the powered tool. An elongated inner member is received within the outer tube and has an inner hub adapted to be driven by the surgical tool. The dimensions of the outer tube and inner member are such as to form an annular channel therebetween for the passage of irrigating fluid. The inner member carries a cutting tool, such as a burr, at its distal end, the tool being accessible through an aperture in the outer tube. A bearing member is located in the annular channel between the inner member and the outer tube, and a bypass channel runs external to the outer tube to carry irrigating fluid to the cutting tool bypassing the bearing member. An aperture through the outer tube connects the annular channel with the bypass channel.
