CORDLESS, POWERED SURGICAL TOOL

摘要

A powered tool (20) for performing surgical procedures. The tool (20) includes a handpiece (22) in which a power generating unit (26) is housed. A control member is mounted to the handpiece (22). The control member (38) is mounted to the handpiece (22) so that the orientation of the control member (38) can be selectively set relative to the point to which it is mounted to the handpiece (22) and so it can move relative to a reference point on the handpiece. A control module (36) monitors the orientation of the control member (38) and its position relative to the reference point. Based on the control member (38) orientation and position, the control module (36) generates signals to regulate the operation of the power generating unit (26). When the power generating unit (26) is a motor, the control module generates signals to ensure that the maximum speed at which the motor can be driven is less than the no load speed.
