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.

The present invention provides 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 on 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
A retractor clamp is provided for a low profile retractor system including a spreader including first and second arms joined by a cross-bar. The first and second arms define an arm level. The refractor clamp includes a gripping assembly, a main body, an extension arm, a retractor blade arm, and a securement assembly. The refractor 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 refractor blade arm is joined to the main body by the extension arm, and is positioned at a refractor blade arm level above the arm level. The refractor blade arm accepts a blade clamp. The securement assembly includes an adjustment member accessible by an operator substantially at the arm level. The securement assembly is operatively connected to the gripping assembly.
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.
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. In the illustrated embodiment, a pawl mechanism is connected to the adaptor housing and configured for automatic engagement with at least one of a plurality of serrations that are located on the non-cylindrical retractor blade handle, thereby allowing for the efficient adjustment and automatic locking of the linear position of the non-cylindrical retractor blade handle relative to the operative site.
