    Abstract: A femoral component of a knee prosthesis, wherein the femoral component includes a sharp radius at each end (e.g., the anterior end and the posterior end) of the femoral component is disclosed herein. The sharp radius at each end may form a “claw” at each end. Each of these claws may “dig” through the patient's cartilage into the bone (or may “dig” directly into bone if there is no intervening cartilage). One benefit provided by a claw may be facilitating a smooth transition of cartilage/poly bearing to femoral implant/poly bearing (e.g., during knee extension). A femoral component of a knee prosthesis, wherein the femoral component includes a raised rib having a bulbous terminus at a free edge is disclosed herein. This raised rib having a bulbous terminus at a free edge may, for example, simultaneously create sufficient implant strength and adequate cement fixation while minimizing the component's thickness.

    Abstract: The retractor system for use in spinal surgery and other types of surgical procedures that is a simple and efficient solution for minimally invasive access to thoracolumbar spine is disclosed. The fully customizable design allows the surgeon to independently angle the retractor blades and expand the retractor in both cephalad-caudal and medial-lateral directions. With an offering of a range of blade lengths, access can be tailored to the patient's anatomy. Auxiliary instruments such as the retractor inserter, universal hex driver and blade removal instrument allow quick and controlled access to the surgical site. The retractor system provides versatility and control ensuring minimal tissue trauma.

    Abstract: A counter-balanced oscillating surgical saw for use in surgical procedures is described which greatly reduces the vibrations caused when the saw blades contact the patient's anatomy. The reduction of vibration is achieved by the present saw which uses two oscillating blades to counter the kinetic energy typically lost when only one blade is used. The preferred embodiment of the present invention includes at least two cutting blades mounted on at least two actuator blocks. The actuator blocks are preferably mounted on at least two shafts which extend from the top of the saw handle: a pivot shaft and a rotatable shaft which is rotated by an electric motor. At least two eccentric bearings are mounted to the rotatable shaft (one bearing for each actuator block) such that the bearings orbit about the rotatable shaft 180.degree. out-of-phase with respect to one another. The actuator blocks are positioned adjacent the eccentric bearings so that they move in a reciprocating manner about the rotatable shaft of the saw. The to-and-fro motion of the actuator blocks is transformed into a counter-balanced oscillating motion of the cutting blades. Mechanical vibration, rotational and linear momentum of the saw is greatly reduced during surgery because as the cutting blades oscillate about the point of incision, the momentum produced by one cutting blade is offset by the momentum produced by its counterpart cutting blade.

    Abstract: A locking surgical tool handle system. The invention includes a surgical tool handle that has an elongated body portion with a pistol-type grip. The front end of the handle body has a tool retaining structure comprising a contoured engagement face and a moveable tension bar with an engagement end. Projections on the engagement end of the tension bar fit within a receiving channel of a surgical tool, such as a broach or rasp. A locking mechanism is provided within the handle body, and is implemented with pivotable links attached to the tension bar. The locking mechanism has an unlocked position in which the engagement end of the tension bar is spaced away from the engagement face of the handle body, and an over-center locked position in which the engagement end of the tension bar is retracted toward the handle body. When the tool handle is placed in its locked position, the engagement end of the tension bar pulls an attached tool into tight contact with the engagement face of the handle body.
