A surgical instrument system is disclosed which comprises a distal end and a staple cartridge assembly comprising staples removably stored therein. The instrument system further comprises a firing drive including an electric motor and a firing member operably couplable with the electric motor. The electric motor is operable to advance the firing member toward the distal end during a staple firing stroke to eject the staples from the staple cartridge. The electric motor is operable to retract the firing member away from the distal end during a retraction stroke. The surgical instrument system further comprises a manually-operated bailout mechanism operable to perform the retraction stroke in lieu of the electric motor, a controller, and a display in communication with the controller. The controller is configured to display the progress of the retraction stroke when the firing member is being manually retracted by the bailout mechanism.

A surgical instrument (10) includes a handle assembly (20), an elongate body portion (50) extending from the handle assembly (20) and defining a longitudinal axis, and a rotation assembly (100) rotatably securing the elongate body portion (50) to the handle assembly (20). The rotation assembly (100) includes a sleeve member (110) and a rotation knob (120) supported about the sleeve member (110). The rotation knob (120) is movable relative to the sleeve member (110) and the handle assembly (20) along the longitudinal axis.

The present invention is an apparatus, device or tool for performing endoscopic (that is, minimally invasive) surgery. An exemplary embodiment of the invention includes a video endoscope whilst in another embodiment of the invention includes an endoscopic surgical tool which, when equipped with one of a suite of endoscopic surgical instruments, can be used by a surgeon to perform surgical procedures inside a body. Another embodiment of the present invention includes a suite of endoscopic surgical instruments designed to work co-operatively with the endoscopic surgical tool. In another embodiment of the present invention, a video-assisted endoscopic surgical tool system is provided. In one embodiment, the system includes the video-assisted endoscopic surgical tool and a suite of at least one endoscopic surgical instrument.

Methods and devices for using surgical devices with articulating end effectors are provided. Surgical devices with articulating end effectors can provide rotary driven pivoting of the end effector. In some embodiments, the device can include a handle, a first and a second tube extending from the handle, the second tube disposed within the first tube, and an end effector that includes a pair of distal jaws configured to move in response to rotation of the first tube about a longitudinal axis thereof and rotation of the second tube about a longitudinal axis thereof. The jaws can move in two different ways depending on whether the first and second tubes are rotating in a same direction as one another or in different ways than each other. The jaws can open/close and articulate using the same mechanical mechanism. The device can be powered, or the device can be non-powered.

The aim of the invention is to move a medical instrument (2) by means of a medical device (1) in the longitudinal direction of the device and in the rotation direction transversely about the longitudinal direction by an actuating apparatus (3). This aim is achieved in that the medical instrument (2) is connected to at least one first magnetic element (18, 19) and the actuating apparatus (3) contains at least one second magnetic element (20, 21) or is connected thereto; the actuating apparatus (3) is movable together with the at least one second magnetic element (20, 21) in the longitudinal direction of the device and in the rotational direction about the longitudinal direction in question and is movable together with the at least one second magnetic element (20, 21) in the longitudinal direction of the device and in the rotational direction about the longitudinal direction in question and permits, by means of magnetic coupling between the at least one second magnetic element (20, 21) and the at least one first magnetic element (18, 19), moving same together with the medical instrument (2).

A medical device includes a handle with a proximal arm and a distal arm. The proximal arm and the distal arm are pivotable via a joint. The medical device also includes a tube coupled to the distal arm and a drive wire. A distal portion of the drive wire includes an expandable end effector. A portion of the drive wire is positioned within the tube, and a different portion of the drive wire extends proximally of the distal arm and is coupled to the proximal arm.

The application relates to a medical instrument with a hollow shaft, with a handle at the proximal end and a tool with two jaw parts at the distal end, of which at least one jaw part is pivotable, wherein a distal end region of the shaft is configured as a deflectable, rotatable tool tip, and wherein the jaw parts are adjustable between closed and open positions, wherein rotation of the tool tip and actuation of the jaw parts take place via actuation elements coupled at the proximal end to the handle. The distal end of the shaft and the proximal end of the tool tip are arc-shaped, and roll on each other for the deflection of the tool tip, and are conveyed from the shaft into the deflectable tool tip via at least two identical joints, which are connected in series and which can transmit rotation and translatory movements.

A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

Embodiments of the present invention provide an improved surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector is capable of several different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one of the operations is controlled by a trigger mechanism contained within the handle. In some embodiments, the end effector includes a pair of curved jaw members and a blade assembly having a cutting blade at its distal end. The trigger mechanism is arranged to drive the blade assembly longitudinally within the elongate shaft such that the cutting blade protrudes between the jaw members. In order to help the trigger mechanism push the blade assembly around the curved jaws, the distal end of the blade has a graduated flexibility such that it can more easily bend to the shape of the jaw members. The distal end of the blade may also be provided with a low friction coating so that it can more easily slide between the jaw members.

A medical device includes a first link, a second link, and a band. A proximal end portion of the first link is coupled to a shaft. A proximal end portion of the second link is rotatably coupled to a distal end portion of first link about a first axis. The distal end portion of the second link includes a connector coupled to a tool member that is rotatable relative to the second link about a second axis that is non-parallel to the first axis. The first link defines a first guide channel and the second link defines a second guide channel. A distal end of the band is disposed within the first guide channel and the second guide channel, and is coupled to the tool member. The second link is rotatable relative to the first link about the first axis when the distal end of the band is moved.
