Abstract: Co-axial actuated scissors for slidable positioning along a nerve for cutting the nerve or other anatomical surgical structure in a plane normal to the longitudinal axis of the scissors and away from the surgery site without harming adjacent tissues includes a first scissor portion having an offset handle attached to a slotted cylinder and a second scissor portion having an offset handle attached to an inner cylindrical member with the inner member telescoped within the slotted cylinder for concentric rotation therewith and the slotted cylinder and rotating member defining the longitudinal axis such that the cylinder and the rotating member include a loop end comprising a pair of cutting jaws whose cutting action is normal to the longitudinal axis and which are movable from an open position to a gripping position to a fully closed position for cutting the nerve through rotatable concentric actuation of the rotating member relative to the slotted cylinder and with detents positioned on an arcuate arm of the fi

Abstract: A slotted bone rasp for reciprocal planing of opposed bone surfaces joined by a fixation pin so that the bone surfaces are made congruous and parallel to each other preparatory to bone fusion irrespective of pin orientation includes a shank with a pair of legs defining a slot for accommodating the pin and the legs having a flat side and an opposed abrasive side for remodeling the bone surfaces. Each leg includes an inner opposed convex surface whereupon the slot is narrowest at its midline so that the rasp is laterally pivotal transverse to the pin axis providing oblique angulations of the plane of bone removal relative to the pin axis; and the rasp also being rotatable to at least 90 degrees arc of rotation about the pin for 360 degree coverage of the bone surface creating two parallel bone surfaces in maximal end-to-end contact for successful bone fusion.

Abstract: A disposable wound measuring device for making simultaneous three-dimensional (length, width and depth) measurements of a wound or ulcer to facilitate wound care assessment and healing that includes a flexible, clear plastic planar card or member superposed on the wound and having a centrally located aperture and concentric circles radially arranged about the aperture, and an elongated depth gauge insertable through the aperture and incrementally adjustable either vertically or obliquely through the aperture and relative to the wound surface and the plastic member for making a wound depth measurement with the depth gauge being retained in position by a plurality of beads equidistantly spaced along the gauge and slightly larger in diameter than the aperture thereby self-retaining the depth gauge in a particular position for making the wound depth measurement.
