Title:
モーター制御された外科用システム
Document Type and Number:
Japanese Patent JP3845116
Kind Code:
B2
Abstract:
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 addressable switch assemblies for generating electrical state signals and the controller is responsive to the state signals for controlling the operation of the motor. The addressable switch assemblies are addressable Hall-effect circuit switches 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 relationship between the duty cycle of a pulse width modulated control signal and the resulting motor armature rotational velocity.
