Abstract
A surgical instrument for performing an energy-based surgical procedure includes an end effector, a trigger assembly, and a position sensing circuit. The end effector includes a jaw assembly movable between an open state and a closed state. The trigger assembly is operable to move the jaw assembly of the end effector between the open state and the closed state. The position sensing circuit includes a position sensor and a position indicator. The position sensor is configured to sense movement of the position indicator and generate sensor data indicative of a position of the jaw assembly based on the sensed movement of the position indicator. A method for monitoring operation of the surgical instrument is also disclosed.
Claims20
A surgical instrument for performing an energy-based surgical procedure, the surgical instrument comprising:
- an end effector having a jaw assembly movable between an open state and a closed state;
- a trigger assembly operable to move the jaw assembly of the end effector between the open state and the closed state;
- and
- a position sensing circuit including a position sensor and a position indicator, wherein the position sensor is configured to sense movement of the position indicator and generate sensor data indicative of a position of the jaw assembly based on the sensed movement of the position indicator.
A method comprising:
- sensing, by a position sensor, movement of a position indicator during operation of a trigger assembly of a surgical instrument to move the jaw assembly between an open state and a closed state, wherein the position sensor and the position indicator are attached to the surgical instrument;
- generating, by the position sensor, sensor data indicative of a position of the jaw assembly based on the sensed movement of the position indicator;
- and
- determining, by a controller of the surgical instrument, the position of the jaw assembly based on the sensor data.
