A molded, plastic support having an upper end and a lower end. Each anchor hole is inclined to allow attachment of one or more sutures to the anchor either before, during or after the anchor is seated in a bone. The housing includes an insertion opening part which exposes the terminal portion outside, a back part positioned at an end part opposite to the insertion opening part in the housing, and a side part provided between the insertion opening part and the back part and configured to oppose to the plug when the plug is inserted into the connector. A releasable latch member on the handle releasably locks the knife blade in the first and second positions, and the sheath cavity is designed to receive the portion of the knife blade which protrudes from the handle in the retracted position, such that the overall length of the assembly is reduced when the knife is sheathed. The location, size, and orientation of the recovered positioning target identify the aiming point of the remote pointing device relative to the display.
