Abstract
A calibration system for a surgical instrument. The calibration system includes an actuator, such as a motor system and a flexible shaft. The calibration system also includes a surgical instrument actuatable by the actuator. The calibration system also include calibration data corresponding to the surgical instrument. A processor is configured to process the calibration data for determining a position of the surgical instrument. The calibration system may include a sensor configured to provide a signal corresponding to a movement of the actuator, the processor being further configured to process the signal for determining a position of the surgical instrument.
Claims29
A method for calibrating a surgical end effector, the method comprising:
- connecting the surgical end effector to a handheld electromechanical driver assembly;
- operating the surgical end effector a first time;
- determining a correction factor;
- storing first calibration data in a memory of the handheld electromechanical driver assembly;
- storing second calibration data in a memory other than the memory of the handheld electromechanical driver assembly;
- storing the correction factor in a memory of the surgical end effector;
- and
- reading, via a processor, at least one of the correction factor, the first calibration data, or the second calibration data for operating the surgical end effector a second time, via the handheld electromechanical driver assembly, in accordance with selection of at least one of the correction factor, the first calibration data, or the second calibration data,
- wherein the first or second calibration data includes data correlating a number of rotations of a rotatable drive shaft of the handheld electromechanical driver assembly to a change in distance between a first component and a second component of the surgical end effector.
