Abstract:
A target socket for a surgical instrument comprising:an annular ring of generally uniform radial thickness and having an outer surface and an inner surface, the ring having a radially oriented gap defined by spaced open end portions and also having at least two radially oriented channels defined in the outer surface and spaced away from the gap, the inner surface being shaped in an arcuate band; anda tangentially oriented tightening member spanning the gap between the end portions of the ring and selectively movable relative to the ring to vary the space of the gap, thereby to selectively vary the radius of the arcuate band, whereby a target may be held fixed in place within the arcuate band or may be rotated relative to the ring while still held within the arcuate band, the at least two radially oriented channels providing flexibility for the ring to open and close upon the target in response to movement of the member.
