CIRCUITRY AND SENSORS FOR POWERED MEDICAL DEVICE
First Claim
1. An electronic system for a surgical instrument, the electronic system comprising:
- a main power supply circuit configured to supply electrical power to a primary circuit;
a supplementary power supply circuit configured to supply electrical power to a secondary circuit; and
a short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit;
wherein the supplementary power supply circuit is configured to isolate itself from the main power supply circuit when the supplementary power supply circuit detects a short circuit condition at the secondary circuit; and
wherein the supplementary power supply circuit is configured to rejoin the main power supply circuit and supply power to the secondary circuit, when the short circuit condition is remedied.

Abstract
An end effector is disclosed. The end effector comprises a first jaw member comprising a magnetic sensor; a second jaw member pivotally coupled to the first jaw member such that the first jaw member is pivotally moveable between an open position and a closed position, wherein the second jaw member is configured to receive a staple cartridge therein; a staple cartridge removably coupled to the second jaw member, the staple cartridge further comprising an upper surface facing the first jaw member; and a magnet positioned to be in an opposing relationship to the magnetic sensor when the first jaw member is in the closed position. The magnetic sensor is operable to detect the magnetic field of the magnet, and wherein the detected magnetic field is indicative of the distance between the anvil and the staple cartridge.
