Abstract
A surgical stapler is disclosed comprising an end effector configured to receive a staple cartridge, a trocar movable relative to the end effector, an anvil removably coupleable to the trocar, a sensor, a housing comprising a display, and a control circuit operably coupled to the sensor and the display. The anvil is movable relative to the end effector based on movement of the trocar. The sensor is configured to sense a position of the anvil relative to the end effector. The control circuit is configured to interrogate the sensor to determine the position of the anvil and display a representation of the determined position on the display.

A surgical stapler, comprising:
- an end effector configured to receive a staple cartridge;
- a trocar movable relative to the end effector;
- an anvil removably coupleable to the trocar, wherein the anvil is movable relative to the end effector based on movement of the trocar, and wherein the anvil is configured to apply a force to tissue positioned between the anvil and the end effector;
- a sensor configured to sense the force;
- a housing comprising a display;
- and
- a control circuit operably coupled to the sensor and the display, wherein the control circuit is configured to:
- interrogate the sensor to determine the force;
- and
- display a representation of the determined force on the display.
