1. A device for use in a medical procedure, the device comprising:
- a body;
a displacement member slideably engaged with and moveable with respect to said body;
a shaped aperture provided on one of the body or the displacement member, the shaped aperture having a first shaped portion and a second shaped portion, the first shaped portion including an inner surface with a cross-section having a non-circular segment;
an adjustment member disposed within the shaped aperture; and
a biasing member;
wherein contact of the adjustment member with the non-circular segment prevents the adjustment member from being at least one of rotated or translated relative to the body or displacement member;
wherein the adjustment member is capable of being at least one of rotated or translated relative to the body or displacement member when the adjustment member is positioned adjacent to the second shaped portion; and
wherein the biasing member is configured to normally position the adjustment member adjacent to said first shaped portion.

Abstract
Disclosed are lockable instrument assemblies for quick and easy configuration of surgical instrumentation. The assemblies are operable between a locked and unlocked position, and generally include an aperture having a shaped profile which receives an adjustment member therein. When the assemblies are placed in a locked assembly configuration, the adjustment member is prevented from rotating or translating within the aperture. When the assemblies are placed in an unlocked assembly configuration, the adjustment member is permitted to rotate or translate within the aperture. Also disclosed are methods of using and making lockable instrument assemblies.
