Abstract:
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 an 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 the 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 microprocessor receive power when the staple cartridge is positioned within the channel, and the system is operable to identify the staple cartridge.

Abstract:
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 an elongated channel; an anvil having a staple forming surface is moveable relative to the elongated channel between an open position and a closed position; and a staple cartridge removably positioned within the elongated channel. The staple cartridge comprises a body having a tissue contacting surface in a confronting relationship with the staple forming surface; a plurality of staple drivers within the cartridge body each supporting a staple; and a tissue thickness compensator positionable between the anvil and the cartridge, the tissue thickness compensator is captured by the staples and assumes different compressed heights within the different staples. The tissue compensator comprises first conductive elements. The system determines properties of tissue compressed between the anvil and the cartridge.
Abstract:
A surgical instrument is disclosed. The surgical instrument includes a first jaw and a second jaw, wherein at least one of the first jaw and the second jaw is movable relative to the other one of the first jaw and the second jaw between an open configuration and an approximated configuration. In addition the surgical instrument includes a cutting member movable during a firing stroke to cut tissue captured between the first jaw and the second jaw, the cutting member comprising a cutting surface at a distal portion thereof. In addition, the surgical instrument further includes a sensing module operable to measure a characteristic of the cutting surface.
Abstract:
A surgical instrument includes a surgical end effector having a receiving portion for removably receiving therein an interchangeable part. The receiving portion has a communication connection. A handle connected to the end effector actuates the end effector. The handle has a controller electrically connected to the communication connection for authenticating the interchangeable part when placed at the end effector. An interchangeable part is removably connected to the receiving portion and has an encryption device electrically removably connected to the communication connection when placed at the receiving portion. The encryption device authenticates the interchangeable part when queried by the electric controller.
Abstract:
A subject on a pallet (22) undergoes a surgical procedure in the vicinity of an MR scanner using non-MRI compatible instruments (40) from a tray (42). The procedure may, for example, insert a catheter which is MRI compatible. After the procedure, the pallet (22) is transferred by a transfer gurney (26') or a drive (122) and moved across a 5 Gauss line (32) and into an imaging region (30) of an MRI scanner (12). To be sure that none of the non-MRI compatible instruments crosses the 5 Gauss line (32), a circuit (50) senses whether all of the instruments have been repositioned at their preselected locations in the tray (42). The circuit (50) controls one of a light (60) which indicates whether or not it is safe to cross the 5 Gauss line, prevents brakes on the movable transport gantry (26) from being released, prevents a pallet manipulating mechanism (24) from transferring the pallet to the transport gantry, or prevents the transport gantry from being released from its docking position with the manipulating mechanism (24).
