An ultrasonic surgical instrument includes a body, an ultrasonic supported by the body, a shaft extending distally from the body and defining a shaft axis, a waveguide extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade coupled to a distal end of the waveguide and having a primary blade treatment surface configured to treat tissue, and a clamp arm coupled to the distal end of the shaft. The shaft and the waveguide are selectively rotatable relative to one another about the shaft axis through a predefined range of angular motion between an assembly state and an operational state. In the assembly state, the clamp arm and the primary blade treatment surface are rotationally offset from one another. In the operational state, the clamp arm and the primary blade treatment surface are rotationally aligned.

A biopsy marker introduction assembly is configured for introduction through a specimen retrieval recess into a probe cutter lumen of a handheld breast biopsy handle. Advancing the cutter causes an extending deployment rod to distally translate within an introducer tube of the introduction assembly, pushing a biopsy marker out of a distal end of the probe at a surgical biopsy site. Thereby, the surgeon is able to position the probe and effect deployment of the marker even if using the other hand to position an imaging device such as an ultrasonic transceiver.

Marker device and method of deploying a cavity marker using a surgical biopsy device

The present invention is directed to an improved cable driven surgical biopsy device wherein a transmission assembly is disposed at a proximal end of the biopsy device. The transmission assembly being adapted to convert rotational motion of a cable entering the biopsy device of a substantially right angle into rotational energy to drive the axial cutter in the biopsy device.

An applier for delivering and deploying a biopsy marker to a surgical biopsy site is disclosed. The applier has a ferrule with a forming surface to form the marker on the distal end of a flexible tube. The marker is held at the distal end of the flexible tube in a marker holder. A forming rod slidable in the flexible tube urges the marker into contact with the forming surface of the ferrule for marker formation. The distal end of the flexible tube is delivered through an egress tube, which in turn is delivered through a biopsy cannula adapted for taking the biopsy sample. The egress tube has an alignment hub at its proximal end adapted for orientational alignment with a hub receiver on the biopsy cannula. When properly aligned, the egress opening of the distal end of the egress tube is orientationally aligned with the biopsy port of the biopsy cannula for proper delivery and deployment of the marker.

Applier for implantable surgical marker

An implantable marker for implantation in tissue of a surgical patient is disclosed. The marker has a base and an elevated bridge. A pair of legs descend from first and second transitions of the bridge. Each leg has a distal tip, a generally straight leg arm adjacent the tip, and a camming marker surface between the transitions of the base and the straight leg arm. The camming marker surfaces extend outwardly from the straight leg arms of the legs. In its open configuration, the first and second straight leg arms of the legs of the marker are generally parallel to each other. In its closed configuration, the first and second straight leg arms converge towards each other, and a marker apex is formed at the distal tips of the legs. The marker is particularly adapted for fixation in tissue to mark the site of a lesion or other abnormal tissue which may be removed during a biopsy procedure, for example a breast biopsy procedure. Advantageously, the camming marker surfaces of the legs of the marker facilitate the ability to form the marker upon pushing the marker distally into the tissue, thus insuring deep penetration of the marker and the grasping of a sufficient amount of tissue to securely fix the marker to the tissue.

A clip, clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier. The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.
