SURGICAL STAPLER HAVING MAGNETIC FIELD-BASED MOTOR CONTROL

摘要

A surgical stapler. The surgical stapler includes a drive system, an electric motor, a battery and a control system. The electric motor is mechanically coupled to the drive system. The battery is electrically couplable to the electric motor. The control system is electrically connected to the electric motor and is configured to control the electric motor based on a magnetic field measured proximate the electric motor.
