The instrument includes a stationary member defining an aperture. The stationary member is arranged relative to the movable member with a close fit between the stationary member and the movable member such that aspiration occurs through the movable member substantially only during a portion of a repetitive motion of the movable member. The instrument includes a surgical handpiece coupled to the movable member and the stationary member to provide suction and motion to the movable member. A method of regulating aspiration through a surgical instrument includes providing a close fit between a moving member having an opening at a proximal portion and a stationary member having an aperture such that aspiration occurs through the moving member substantially only during a portion of a repetitive motion of the movable member. The moving member and the stationary member are coupled to a surgical handpiece to provide suction and motion to the moving member.

摘要： One surgical device includes a first member and a second member defining a lumen for receiving the first member. The first member is configured to be movable relative to the second member to cut tissue. An electrical connector is physically and electrically coupled to the second member, to electrically couple the second member to a source of electricity. A tension device holds a distal region of the first member in electrical contact with a distal region of the second member. The first member includes a blade used both to cut tissue mechanically, and to coagulate cut tissue. The blade is electrically conductive and serves as an active electrode in a bipolar arrangement with a return electrode. Electrical energy is transferred to the blade through a point contact at a distal tip of the first and second members.

摘要： An apparatus for controlling a surgical device includes a housing and a magnetic switching element mounted on the housing. The magnetic switching element includes a magnet, a magnetic sensor configured to produce a control signal for controlling the surgical device, and an actuator mounted on the housing for movement between a first position in which a magnetic field of the magnet is decoupled from the magnetic sensor and a second position in which the magnetic field is coupled to the magnetic sensor so as to change a value of the control signal produced by the magnetic sensor. The magnetic switching element may also include magnetically soft material positioned so that movement of the actuator causes relative movement between the magnet and the magnetically soft material.

摘要： A method for removing a vein includes making an incision through a skin layer of a patient, inserting a surgical instrument through the incision, visualizing the vein through the skin layer using a light source positioned subcutaneously and in proximity of the vein, and cutting the vein using the surgical instrument. The vein can be visualized by directing light from the light source at the vein from underneath the vein or from a side of the vein. A device for illuminating a body structure has a housing with a distal end configured for subcutaneous insertion into a patient's tissue and positioning in proximity of the body structure, a light path supported by the housing and configured for directing light at the body structure, and a fluid line supported by the housing.

摘要： A surgical system, adapted to operate with at least one surgical device, has a handpiece containing a motor which is adapted to receive the surgical device. The surgical device is driven through a continuum of positions by the motor output shaft. A controller microprocessor controls the operation of the system. The motor has sensors for generating electrical position signals and the controller is responsive to input signals for defining both a stop position and a reversal position for the surgical device. As a result, the controller initiates operation of the surgical device at the so called stop position and stops operation of the surgical device so that it comes to rest substantially at the stop position. In an oscillatory mode of operation, the controller also forces reversals to occur solely at a reversal position dictated by the system, under the control of the user. In connection with an arthroscopic cutting device, the control enables the surgeon to control, for example, the opening of the aperture through which tissue and fluids are removed from the surgical site during the reversal and start/stop conditions.
