ABSTRACT:
A table-mounted surgical retractor support includes a wishbone-shaped structure comprising two identical rods which are separately attachable to a clamp located at the end of a supporting rod. The supporting rod is, in turn, connected to a similar clamp located at the top of a table-mounted post. The two parts of the wishbone structure are small enough to be sterilized conveniently.
The wishbone rods cannot be rotated in their clamp, nor can the supporting rod be rotated in its clamp. However, the wishbone clamp, when loosened, allows rotation of the wishbone structure about the supporting rod axis and also about an axis mutually perpendicular to the supporting rod axis and the wishbone plane. Likewise the supporting rod clamp allows rotation of the supporting rod about the axis of the post and about an axis mutually perpendicular to the supporting rod and the post. Each clamp is designed to apply a shear to the rod on which it is supported, thereby achieving a tight clamping action.
