    Abstract: A surgical device includes a forceps and a blade. The forceps includes a first working jaw and a second working jaw. The blade extends along a longitudinal axis and includes a notched section. The blade is located between the first working jaw and the second working jaw. A first therapy current can be connected to the first working jaw, the second working jaw, or both so that tissue gripped between the first working jaw and the second working jaw and within the notched section can be coagulated. While the tissue is gripped between the first working jaw and the second working jaw, the blade is moveable along its longitudinal axis so that the tissue is cut with the notched section without repositioning the first working jaw, the second working jaw, or both.

    Abstract: Disclosed is a medical device comprising an outer elongate member having a proximal end, a distal end, and a lumen extending therethrough; an inner elongate member disposed within the lumen of the outer elongate member and configured to be axially movable inside the lumen of the outer elongate member, the inner elongate member having a proximal end portion, a distal end portion, and a lumen extending therethrough; an expandable cage-like scaffold having a proximal end secured to the distal end of the outer elongate member and a distal end having an inwardly everted tapering framework, the cage-like scaffold composed of a plurality of wires that cross each other at points, and capable of being actuated between a substantially folded configuration and a substantially open configuration. Also disclosed is a method of employing the above disclosed device or variations thereof to capture and remove stones or stone fragments from the body's lumen of a subject.

    Abstract: A surgical device comprising: a handle assembly; a locking collar; and a set of replaceable bits that load along an axis into the handle assembly; wherein the locking collar is fully removable from the handle assembly, the locking collar loads axially to a first position, and the locking collar rotates between the first position and a second position; wherein, in the first position, the locking collar is free to be axially removed from the handle assembly and the replaceable bits are free to be loaded or unloaded from the handle assembly; wherein, in the second position, the locking collar is prevented from axial movement relative to the handle assembly and the replaceable bits are prevented from being received within, or removed from, the handle assembly; and the locking collar is guided to the first position and between the first position and the second position by a groove in the handle assembly mating with a member carried by the locking collar. And a surgical device comprising: a handle assembly comprising a rotatable drive shaft; a removable handle assembly adapter for connection to the handle assembly, the removable handle assembly adapter comprising a rotatable transmission shaft for connection to the rotatable drive shaft of the handle assembly; and a removable nosepiece assembly for connection to the removable handle assembly adapter and for selectively securing the shaft of a working element to the rotatable transmission shaft of the removable handle assembly adapter; wherein the removable handle assembly adapter and the removable nosepiece assembly each comprise a locking collar; and wherein the removable handle assembly adapter and the handle assembly each comprise a connector assembly, the connector assembly comprising: a housing comprising an opening; a collet sleeve disposed within the opening and connected to an input shaft, the collet sleeve comprising a lumen for receiving an output shaft; a locking element movable relative to the collet sleeve between (i) a locked position in which the output shaft is secured to the collet sleeve, and (ii) an unlocked position in which the output shaft is not secured to the collet sleeve; and a cam element movable relative to the collet sleeve between (i) a first position in which the locking element is free to assume its unlocked position, and (ii) a second position in which the cam element cams the locking element into the locked position; such that movement of the locking collar causes the cam element to move between the first position and the second position.
