Handheld electromechanical surgical device with strain gauge drift detection

According to one embodiment of the present disclosure, a surgical device is disclosed. The surgical device includes a motor and a transmission assembly movable by the motor. The surgical device also includes a force sensor configured to measure a force applied on the transmission assembly. The apparatus may also include a controller configured to control the motor to move the transmission assembly to a starting position, interrogate the force sensor to receive a sensor signal, compare the sensor signal to a threshold value, and determine whether the force sensor is malfunctioning based on the comparison of the sensor signal to the threshold value. 根据本披露内容的一个实施例，披露了一种手术装置。该手术装置包括电机和可通过该电机移动的传动组件。该手术装置还包括力传感器，该力传感器被配置为测量施加在传动组件上的力。该装置还可以包括控制器，该控制器被配置为：控制电机以将传动组件移动到起始位置，询问力传感器以接收传感器信号，将传感器信号与阈值进行比较，并基于传感器信号与阈值的比较来确定力传感器是否有故障。
