Claim 12:
13. A surgical pin positioning lock comprising:
a bearing retaining body defining a pin receiving hole extending axially therethrough, the bearing retaining body defining a bearing receiving cavity extending from an outer perimeter surface to the pin receiving hole and including a bearing contained therein;
a piston defining at least one sidewall and a top wall which, collectively, form a cavity, the top wall of the piston defining a pin receiving hole extending therethrough, the at least one sidewall defining an inward taper over at least a portion of its length;
a biasing member; and
a base defining at least one sidewall and a bottom wall,
wherein the bearing retaining body is at least partially inserted into the cavity of the piston with the pin receiving hole of the bearing retaining body being axially aligned with the pin receiving hole extending through the top wall of the piston,
the biasing member is positioned between the bearing retaining body and the top wall of the piston and configured to bias the bearing retaining body away from the top wall of the piston,
the piston is configured to move relative to the bearing retaining body, causing the inward taper on the at least one sidewall to move relative to the bearing and thereby causing the bearing to move into or out of the pin receiving hole, and
the bearing retaining body is positioned at least partially between the bottom wall of the base and the biasing member.
