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. 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.
