摘要： A surgical system (8), adapted to operate with at least one surgical device, has a handpiece containing a motor (10) which is adapted to receive the surgical device. The surgical device is driven through a continuum of positions by the motor output shaft (12). A motor (10) has addressable switch assemblies for generating electrical state signals and the controller is responsive to the state signals for controlling the operation of the motor (10). The addressable switch assemblies are addressable Hall effect circuit switches (14) connected to the controller over a two wire switch bus. In connection with an arthroscopic device, the system enables the surgeon to control operation of the device from the handpiece. The surgical control system also provides a more linear relaionship between the duty cycle of a pulse width modulated control signal and the resulting motor armature rotational velocity.

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 at a reversal position dictated by the system, under the control of the user, unless a stall condition is sensed, in which case the reversal takes place as soon as possible. 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.

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 continum of positions by the motor output shaft. A controller microprocessor (16) controls the operation of the system. The motor has sensors for generating electrical position signals (22) and the controller (16) is responsive to input signals for defining both a stop position and a reversal position for the surgical device. As a result, the controller (16) 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 (16) 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.

摘要： A system (100) for treating tissue includes a device including a first member and a second member arranged to move relative to the first member to treat tissue. The system also includes a processor (123) configured to automatically control movement of the second member relative to the first member using position control methodology. A method of treating tissue includes providing a device having a first member and a second member arranged to move relative to the first member, moving the second member relative to the first member, and automatically controlling the movement of the second member using position control methodology.
