Abstract
A powered surgical handpiece including a housing, a printed circuit board, a sensor, and an actuator assembly. The housing has a longitudinal axis extending from a first end to a second end of the housing. The printed circuit board has a first face and a second opposing face. The first and second faces extend perpendicular to the longitudinal axis. The sensor is coupled to the first face of the printed circuit board. The sensor is centered along the longitudinal axis of the housing. The actuator assembly includes a lever and an actuator. The lever is pivotally coupled to the housing. The lever maintains a magnet slidably positionable along the lever. The magnet is positionable to be proximal to the sensors.
Claims12
A powered surgical instrument, comprising:
- a housing having a central longitudinal axis extending from a first end to a second end of the housing along a center of the housing;
- a printed circuit board having a face extending perpendicular to the central longitudinal axis;
- a sensor coupled to the face and disposed on and centered along the central longitudinal axis;
- and
- an actuator assembly including a lever and an actuator, the actuator assembly coupled to the housing to rotate about the central longitudinal axis with respect to the housing, the lever pivotally coupled to the housing, the lever maintaining an actuator slidably positionable along the lever, the actuator positionable to be proximal to the sensor, the actuator assembly having a magnet and operable to vary a magnetic field relative to the sensor.
A control for a powered surgical instrument, the control comprising:
- a housing having a central longitudinal axis extending along a center of the housing from a first end of the housing to a second end of the housing;
- a sensor mounted to a printed circuit board within the housing, the sensor disposed on the central longitudinal axis;
- and
- an actuator assembly including a lever pivotally coupled to the housing and coupled to the housing to rotate about the central longitudinal axis with respect to the housing, the lever including a magnet, the lever operable to move the magnet relative to the sensor in order to vary a signal that is produced by the sensor in response to a magnetic field of the magnet.
