If the components of a surgical instrument are not properly calibrated, errors may occur in the operation of the surgical instrument and consequently a control system for controlling the surgical instrument may lose its effectiveness. This problem may be complicated where a variety of different types of surgical instruments are used with an electro-mechanical device. The present invention provides a system for calibrating a surgical instrument comprising: an electro-mechanical actuator including a memory unit storing at least predetermined calibration data for a number of different surgical instruments; a surgical instrument of the number of surgical instruments actuatable by the electro-mechanical actuator, the surgical instrument having first and second components that are moveable relative to each other; each surgical instrument including a memory unit storing at least predetermined calibration data corresponding to the surgical instrument, wherein the calibration data of each surgical instrument corresponds to a position of the surgical instrument, the position of the surgical instrument being a position of the first and second components relative to each other, wherein the calibration data of the surgical instrument includes a correction factor that corresponds to a difference between an actual amount of actuation required to actuate the surgical instrument from a first position to a second position, and an expected amount of actuation required to actuate the surgical instrument from the first position to the second position; and a processor configured to determine a position of the surgical instrument in accordance with at least one of the predetermined calibration data of the electro-mechanical actuator and the predetermined calibration data of the surgical instrument. |
