Abstract
A surgical instrument is provided for cutting bone and other tissue. The instrument includes a housing. A plurality of sensors are located in the housing in a spaced apart orientation from each other. A collar is moveably mounted to the housing into a plurality of different collar orientations on the housing. A lever comprising an actuator is moveably coupled to the collar and, with the collar located in any one of the plurality of different collar orientations, the lever is operable to move the actuator relative to one of the plurality of sensors in order to vary a signal produced by that sensor.
Claims20
A control for a powered surgical instrument, the control comprising:
- a housing;
- a plurality of sensors located in the housing in a spaced apart orientation from each other;
- a collar moveably mounted to the housing into a plurality of different collar orientations, wherein each of the plurality of different collar orientations corresponds to a respective one of the plurality of sensors;
- and
- a lever comprising an actuator and moveably coupled to the collar, wherein, with the collar located in any one of the plurality of different collar orientations, the lever is operable to move the actuator relative to the respective one of the plurality of sensors in order to vary a signal that is produced by that sensor due to the relative movement of the actuator.
A powered surgical instrument, comprising:
- a housing;
- a motor housed in the housing;
- a cutting tool coupled to the housing and the motor;
- a plurality of sensors coupled to the motor and housed in the housing in a spaced apart orientation from each other;
- a collar rotatably mounted to the housing, wherein the collar is operable to rotate about the housing into a plurality of discrete collar orientations, and wherein each discrete collar orientation corresponds to a respective one of the plurality of sensors;
- and
- a lever comprising an actuator and pivotally coupled to the collar, wherein, with the collar located in any one of the plurality of discrete collar orientations, the lever is operable to pivot in order to move the actuator relative to the respective one of the plurality of sensors and vary a signal that is produced by that sensor due to the relative movement of the actuator and that results in the motor varying the speed of the cutting tool.
A method for controlling a surgical instrument, the method comprising:
- providing a surgical instrument comprising a housing, a collar rotatably coupled to the housing, and a lever comprising an actuator and pivotally coupled to the collar, wherein the collar is located in a first collar orientation on the housing, and wherein the first collar orientation corresponds to a first sensor in the housing;
- pivoting the lever to move the actuator relative to the first sensor in order to vary a signal that is produced the first sensor due to the relative movement of the actuator;
- rotating the collar into a second collar orientation on the housing, wherein the second collar orientation corresponds to a second sensor in the housing;
- and
- pivoting the lever to move the actuator relative to the second sensor in order to vary a signal that is produced by the second sensor due to the relative movement of the actuator.
