摘要:
A surgical instrument includes an end effector with a first jaw and a second jaw. The instrument also includes a first drive assembly, a first motor coupled to the first drive assembly, a second drive assembly, a second motor coupled to the second drive assembly, a control module, and a closure trigger. The first motor is operable to motivate the first drive assembly, and the second motor is operable to motivate the second drive assembly. The control module is operably couplable to the first motor and the second motor. The closure trigger is movable during a closure stroke to transition the end effector to the approximated configuration, and to transition the control module from operable engagement with the first motor to operable engagement with the second motor.

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.

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.

A laparoscopic surgical access device comprises a first frame and a second frame having relative axial positions. A flexible and resilient iris valve is connected to the first and second frames and has a closed position and an opened position based on the relative angular position of the first and second frames. A lock is connected to the first and second frames, the lock being selectively operative to prevent relative rotational movement in a first rotational direction. One embodiment uses a ratchet and pawl mechanism operable with a control ring. Another embodiment uses a ratchet and pawl mechanism operable with a button. Yet another embodiment uses a wedge track and ball mechanism.
摘要:
A laparoscopic device assembly provides a tubular diaphragm twist seal that responds to a slight rotation of an actuating ring in a first direction by coupling a motor spring power assisted rotation of a bottom circumference of the twist seal achieves a pneumatic seal in an adjustable access channel defined by the state of the twist seal for maintaining an insufflated body cavity for a hand assisted laparoscopic surgical procedure. A slight rotation of the actuating ring in an opposite second direction releases compression spring energy and energy in the twisted state of the twist seal so that an upper circumference of the twist seal is allowed to open the adjustable access channel.
摘要:
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.
