A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

Surgical Stapling Apparatus

A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of the cartridge (10) and the anvil (22). The cartridge (10) can be moved towards the anvil (22) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge (10) and is positioned such that there is at least one row of staples on at least one side of the knife.

A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Surgical stapling instrument with an articulatable end effector

A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

An end effector of a surgical instrument may generally comprise a blade, and a clamp arm assembly comprising a clamp arm movable between an open position and a closed position relative to the blade, and at least one camming member rotationally attached to the clamp arm, wherein the at least one camming member is configured to rotate relative to the blade as the clamp arm moves from the open position to the closed position.

Surgical access devices providing seal movement in predefined movement regions

A robotic surgical arm includes a puck containing motors to drive an end effector. A tool assembly attached to the puck generates ultrasonic and/or radio frequency energy to apply to tissue disposed between the jaws of the end effector. The tool assembly can include modular components such as a modular shaft that can include an ultrasonic transducer, nonvolatile memory, wireless interface, and/or a power source. The power source allows the modular shaft to communicate wirelessly with the robotic arm. The tool assembly can be moved from one robotic arm to another while remaining powered by the power source. The tool assembly can include sensors to determine a location or movement of the tool assembly after being detached from the robotic surgical arm. The modular shaft can be moved from a robotic arm to a handle manually controlled by a surgeon and back again to the robotic arm.

A first ultrasonic medical instrument includes an ultrasound transducer, a medical ultrasonic blade, and a tube adapted to contain a liquid A first tube end is adapted to have the liquid proximate the first tube end, when the tube contains the liquid, be ultrasonically vibrated to generate an ultrasonically-vibrating energy wave The ultrasonic blade is acoustically connected to the liquid proximate a second tube end, when the tube contains the liquid A second ultrasonic medical instrument includes a heat pulse initiator, a medical ultrasonic blade, and a tube adapted to contain a liquid The heat pulse initiator is adapted to output heat pulses having an ultrasonic pulse frequency A first tube end is adapted to receive the heat pulses outputted by the heat pulse initiator, wherein the heat pulses have an energy sufficient to create an ultrasonically-vibrating energy wave in the liquid, when the tube contains the liquid

Ultrasonic medical instrument

A surgical instrument for excising a targeted tissue mass to be biopsied from adjacent
bodily tissue of a surgical patient is disclosed. The instrument has an elongated shaft to which is
attached a penetrating member having a penetrating tip (16) to facilitate the insertion of the shaft
adjacent the targeted tissue mass. The instrument also includes a tissue receiving chamber (25) to
receive the targeted tissue mass to be biopsied, and a tissue cutter (26) movable from first to second
positions to excise the targeted tissue received in the tissue receiving chamber. The penetrating tip
includes a blade (19) having first and second planar surfaces (20,21) generally parallel to each other. The blade
reduces the forces necessary to penetrate during insertion of the instrument through the tissue
layers for positioning adjacent the biopsy site. It also serves to facilitate the dilation of the tissue
during insertion. The reduced force to penetrate coupled with tissue dilation reduce patient trauma
and hasten recovery time for the patient.
