END STOP DETECTION
First Claim
1. An electromechanical surgical system, comprising:
- a hand-held surgical instrument including an instrument housing defining a connecting portion for selectively connecting with a shaft assembly;
an end effector configured to perform at least one function; and
the shaft assembly being arranged for selectively interconnecting the end effector and the hand-held surgical instrument, the shaft assembly including;
a drive member;
a flag member configured to translate axially along the first drive member; and
a sensor disposed about the first drive member,wherein the sensor provides a signal indicating that the end effector has reached an end stop when the flag member contacts the sensor.

Abstract
The present disclosure is directed to systems and methods for operating an electromechanical surgical system. The electromechanical surgical system includes a hand-held surgical instrument including an instrument housing defining a connecting portion for selectively connecting with a shaft assembly. The system also includes an end effector configured to perform at least one function. The shaft assembly is arranged for selectively interconnecting the end effector and the hand-held surgical instrument. The shaft assembly includes a drive member, a flag member configured to translate axially along the drive member, and a sensor disposed about the drive member. The sensor provides a signal indicating that the end effector has reached an end stop when the flag member contacts that sensor.

9. An end stop detection method for a powered surgical instrument having a hand-held surgical instrument, an end effector and a shaft assembly including a drive member, a flag member, and a sensor, the method comprising:
-
controlling a motor within the hand-held surgical instrument to cause the drive member to rotate in a first direction thereby causing the flag member to translate axially along the drive member toward the sensor; determining when the flag member contacts the sensor; and stopping the motor when the flag member contacts the sensor. - View Dependent Claims (10, 11, 12, 13)
