An electronic system for a surgical instrument is disclosed. The electronic system comprises a main power supply circuit configured to supply electrical power to a microprocessor, a supplementary power supply circuit configured to supply electrical power to a sensor, and an over current/voltage protection circuit coupled between the main power supply circuit and the supplementary power supply circuit. The over current/voltage protection circuit comprises a current limit switch. The current limit switch comprises a current resistor coupled to an amplifier, wherein, when the amplifier detects a surge current above a predetermined threshold, the amplifier activates a circuit breaker to interrupt the surge current, and wherein when the surge current is remedied, the supplementary power supply circuit rejoins the main power supply circuit and is configured to supply power to the sensor.

An electronic system for a surgical instrument is disclosed. The electronic system comprises 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 sleep mode monitor coupled between the main power supply circuit and the supplementary power supply circuit. The sleep mode monitor is configured to indicate one or more sleep mode conditions. The electronic system further comprises a device state monitor coupled to the primary circuit, the device state monitor configured to sense a state of various electrical and mechanical subsystems of the surgical instrument.

A method of installing a stapler reload cartridge in a stapler instrument includes removing a cover from a side of a stapler reload cartridge housing a plurality of staples, the side having a plurality of pusher apertures configured to receive staple pushers during loading of the stapler reload cartridge; after removing the cover, installing the stapler reload cartridge in the stapler instrument by placing the stapler reload cartridge in a jaw of the stapler instrument such that the side having the plurality of pusher apertures faces the jaw; and after installing the stapler reload cartridge in the stapler instrument, removing a staple retainer from a staple ejection side of the stapler reload cartridge, the staple ejection side comprising a plurality of staple apertures configured to eject staples from the stapler reload cartridge.

An image processing apparatus and an image processing method, according to the present invention, may sense an identifier positioned in a tip to identify unique information such as a serial number of the tip, and may update tip use information assigned to the identified unique information. In some cases, in connection with updating the tip use information, the use information may also be selectively updated based on the type of a scan target to be scanned. Alternatively, a scanning operation of the image processing apparatus may be restricted when a predetermined elapsed time from the removal to the mounting of the tip after scanning an oral cavity is not ensured. Due to the above-mentioned configuration, a user can conveniently recognize when to replace the tip.

The apparatus having a controller connected to and collecting images from the camera, and a display in electrical communication with the controller and/or the camera for displaying medical instrument data pertaining to the movement and/or position of the plurality of medical instruments.

An end effector for use with a surgical stapling instrument is disclosed. The end effector comprises a first jaw, a second jaw movable relative to the first jaw to grasp tissue therebetween, and a staple cartridge. The staple cartridge comprises staples deployable into the tissue. The end effector further comprises a magnetic sensor configured to measure a parameter indicative of an identifying characteristic of the staple cartridge, an impedance sensor configured to measure a parameter indicative of an impedance of the tissue, and a processing unit in communication with the impedance sensor. The processing unit is configured to determine a property of the tissue based on an output of the impedance sensor.

A surgical stapling system including a shaft assembly transmits actuation motions from an actuator and an end effector compresses and staples tissue. The end effector comprises a channel; an anvil having a staple forming surface is moveable relative to the channel between open and closed positions; the anvil having a magnet at a distal end; and a staple cartridge removably positionable within the channel. The staple cartridge comprises a body supported for a confronting relationship with the anvil in its closed position; a plurality of staple drivers located within the cartridge body support a staple; a Hall effect sensor located at the distal end of the body; and a microprocessor in communication with the Hall effect sensor. The Hall effect sensor and the microprocessor receive power when the staple cartridge is positioned within the channel, and the system is operable to identify a staple cartridge.
