Abstract: An ultrasonic surgical device comprises a handle assembly, a shaft assembly, and a removable transducer module. The transducer module includes a waveguide, a locking mechanism, and an electronics assembly including at least one button. The handle assembly includes a trigger assembly configured to actuate the button(s) of the electronics assembly when the transducer module is coupled with the handle assembly. The shaft assembly engages the waveguide of the transducer module and is disposed at the distal end of the handle assembly. The distal end of the shaft assembly includes a harmonic blade. When assembled with the handle assembly, the transducer module is capable of providing ultrasonic energy to the harmonic blade.

Abstract: A surgical device comprises an elongate shaft having an outer tube and an inner rod positioned in the outer tube. The outer tube and inner rod each comprise a distal end and a proximal end. An actuator is operably connected to the proximal ends of the outer tube and the inner rod. An end effector is adapted for in vivo attachment to and detachment from the elongate shaft. The end effector comprises an outer casing comprising a first detent mating feature adapted to engage the distal end of the outer tube; an inner shuttle axially moveable relative the outer casing, the shuttle comprising a second detent mating feature adapted to engage the distal end of the inner rod; and a pair of surgical jaws having an opened position and closed position dependant on the relative axial position of the shuttle and casing. A tubular loader is sized to receive the end effector, the tubular loader comprising third detent mating feature adapted engage end effector.

Abstract: An ultrasonic surgical instrument includes a transmission assembly extending from a body assembly that is configured to selectively couple to a disposable clamp arm. In some versions the clamp arm may include a tab that is insertable into a slot of an inner member such that actuation of the inner member rotates the clamp arm relative to a blade. In other versions the clamp arm may include a ball recess and the inner member may include a rod and ball. The clamp arm may be configured to snap onto the ball and rod. Alternatively, the clamp arm may include living hinges coupleable to an outer sheath and the inner member. Such living hinges may be unitarily formed with a clamp pad on the clamp arm. Further still, the clamp arm may be part of an end effector configured to couple to the transmission assembly via resilient tabs and slots.

Abstract: A surgical instrument includes a body assembly, a waveguide, a transducer, and a coupling assembly. In some versions the coupling assembly translates the transducer to couple the transducer to the waveguide. For instance, a gear having arcuate troughs may engage pins on the transducer and/or waveguide to mate the transducer to waveguide. A pawl may selectively engage and prevent rotation of the gear. Alternatively, lever arms may cam the transducer into the waveguide. The lever arms may selectively couple to a casing to prevent decoupling of the transducer and waveguide. In another configuration, a locking tab can be slid and locked into a slot to couple the transducer and waveguide. Further still, levers with self-locking pins may engage and couple the transducer to the waveguide. In another version, a rotatable body portion may engage a tab on the transducer to rotate and couple the transducer to the waveguide.

Abstract: A biopsy system includes a biopsy device having a translating cutter for severing tissue samples and a vacuum control module. The vacuum control module is separate from the biopsy device. The vacuum control module includes a vacuum pump and vacuum canister, and is portable by a single hand. The vacuum canister and the vacuum control module have complimentary ports that are configured to couple upon insertion of the vacuum canister into the vacuum control module. The complimentary ports provide fluid communication between a vacuum pump in the vacuum control module and a reservoir in the vacuum canister. The biopsy device may be placed in fluid communication with the vacuum pump via the canister without the user having to separately connect any tubes with the canister or pump.

Abstract: A tissue retrieval device includes a tubular member, an expandable member, and a tissue retrieval bag. The introducer tube is sized to be inserted into a patient through a trocar. The bag may be selectively opened by the expandable member within the patient. The bag may receive a tissue specimen and be withdrawn from the patient. The bag may be manipulated for packing within the tubular member in a variety of ways. Manipulation of the bag may include folding the bag about axes that are perpendicular to or parallel to the tubular member; rolling the bag about axes that are perpendicular to or parallel to the tubular member; or wrapping the bag about the expandable member, wrapping the bag about a rod, or twisting the bag at a position distal to the expandable member. The tubular member may comprise an environmentally responsive capsule.

Abstract: A magnetic resonance imaging (MRI) compatible core biopsy system uses a biopsy device having intuitive graphical displays and a detachable remote keypad that advantageously allows convenient control even within the close confines afforded by a localization fixture installed within a breast coil that localizes a patient's breast and guides a probe of the biopsy device relative to the localized breast. A control module for interactive control and power generation are remotely positioned and communicate and transmit rotational mechanical energy via sheathed cable.

Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device.
