Abstract: Certain embodiments provide surgical retractors that include an arm and a blade, the arm including an opening and a first notched surface comprising a plurality of notches that extend radially outward from the opening, the blade including a nipple and a second notched surface comprising a plurality of notches that extend radially outward from the nipple. Attaching the blade to the arm such that the notched surfaces mate can secure the blade relative to the arm such that the blade cannot swivel radially about the opening. Certain embodiments provide methods for securing a retractor blade that can include inserting a nipple on a retractor blade into an opening and mating a first notched surface comprising a plurality of notches that extend radially outward from the opening with a second notched surface comprising a plurality of notches that extend radially outward from the nipple.

Abstract: Certain embodiments of the present invention provide a retractor clamp for a low profile retractor system including a spreader including first and second arms joined by a cross-bar, wherein the first and second arms define an arm level. The retractor clamp includes a gripping assembly, a main body, an extension arm, a retractor blade arm, and a securement assembly. The gripping assembly is sized and adapted to engage at least one of the first arm, second arm, and cross-bar, wherein the retractor clamp is movably and securably joined along the at least one of the first arm, second arm, and cross-bar at substantially the arm level. The retractor blade arm is joined to the main body by the extension arm, and is positioned at a retractor blade arm level above the arm level. The retractor blade arm is sized and adapted to accept a blade clamp for securing a retractor blade thereto.

Abstract: A universal joint apparatus comprises clamps, a locking mechanism, and a rod connecting the clamps and the locking mechanism. At least one clamp is a scissors clamp, i.e. a clamp comprising two segments fastened by a pivot. The scissors clamp generates extra compressive force on the object being held, providing a stable and rigid universal joint. Clamps are able to rotate with respect to each other, allowing for greater flexibility in usage. The universal joint apparatus is capable of being added to a support frame between other components. In one embodiment of the invention, the universal joint includes a dedicated retractor blade handle to ensure that the locked position of the cam handle is oriented substantially away from the operative site.

Abstract: A surgical light apparatus for illuminating a surgical site. The light apparatus may include a light housing, fiber optical cable, a sheath, and a cable connector. The fiber optical cable may be comprised of a bundle of fiber optical cables that have distal and proximate ends. The proximate end may be operably connected to the cable connector, and oriented to receive light emitted from a light source. The distal end of the fiber optical cable may be operably connected to the light housing. The light housing may include a main body and a cover, which either individually, or in combination with each other, provides an outlet at which the distal ends of the fiber optical cables may be dispersed. The light housing may include, or be operably connected to, an attachment mechanism that may attach the surgical light apparatus to a surgical instrument, for example a retractor blade.

Abstract: An adjustable surgical retractor system for clamping system to an operating table. The clamping mechanism includes an upper jaw, lower jaw, a drive member, an adjustable frame support post and releasable locking mechanism for adjusting the height of the surgical retracting frame. The releasable locking mechanism can be a mechanism that includes a sleeve in close sliding relationship to the upper portion of lower jaw member. The upper portion of the lower jaw has a plurality of sockets for receipt of a plurality of balls. The sleeve can have a first position which positions an internal shoulder in alignment with the sockets and urges the balls into engagement with circumferential grooves in post member to lock the post at desired height. In a second position, an internal groove in the sleeve can align with the sockets to allow the balls to move partially out of the sockets and out of engagement with the groove in the post so that the post can be longitudinally adjusted relative to the clamping mechanism.

Abstract: A hinged retractor includes a distal portion adapted to be located inside the body of a patient during a surgical procedure and a proximal portion adapted to be closer to the surgeon during a surgical procedure. The hinged retractor includes a first side including a first blade and a second side including a second blade. The second side is joined to the first side proximate to a distal end of the hinged retractor. The hinged retractor includes a pivot proximate to the distal end. The hinged retractor is movable between a closed position and an open position, wherein a distance between a proximal portion of the first and second blades increases more than a distance between a distal portion of the first and second blades when the hinged retractor is moved from the closed position to the open position.

Abstract: The present invention relates to an apparatus for adapting a non-cylindrical serrated surgical retractor blade handle to the cylindrical bore of a universal joint. The apparatus includes an adaptor housing having a retractor handle passageway, at least a portion of the retractor handle passageway being configured to receive the slideable insertion of a non-cylindrical retractor blade handle. The adaptor housing is configured for rotational insertion into the cylindrical bore of a clamping member, thereby allowing the adaptor housing, the non-cylindrical retractor blade handle, and an attached retractor blade, to rotate about the longitudinal axis of the non-cylindrical retractor blade handle.

Abstract: An emergency medical collar adapted to be moved between a first more flexible state and a second more rigid state includes a body sized and adapted to be fitted to the neck region of a patient, and a chamber disposed inside of the body. The emergency medical collar also includes a support element disposed inside of the chamber. The emergency medical collar is adapted to allow attachment to the neck region of a patient when the neck of the patient is in a variety of positions, for example, neutral, extended, flexed, or lateral.

Abstract: A cervical fixation system comprises a body rigidly attached to a patient's skull at one or more rigid attachment points. One method of achieving such a rigid attachment is through the use of bone screws. The bone screws may comprise a shoulder. The bone screws may further attach to the body of the cervical fixation system. Examples of possible attachment methods include the use of a quick disconnect head, and the use of a threaded body on the bone screw.

Abstract: A rongeur has a frame and a reciprocating member slidably associated with the frame. A blade is disposed on the distal end of the reciprocating member. The frame has a handle that is coupled with the reciprocating member for slideable movement of the reciprocating member. In this fashion, the blade is moved into a cutting position against a footplate formed in the distal end of the frame. A flexure is associated with the handle which allows the handle to be flexed. To reduce the potential for breakage of the footplate, a stop mechanism is provided for preventing further movement of the reciprocating member when the flexure is flexed.

Abstract: A surgical retractor system is provided with an insulating capacity between the retractor blades and surgical table. In particular, the surgical retractor system may include may include a joint clamp with an insulating sleeve within the opening of one of the clamping members. Alternatively, other components of the surgical retractor system may provide the insulating characteristic.
