Abstract:
1. A variable angle instrument assembly, comprising: a handle including an inner member and an outer member, the inner member including a rod and a first tip, the outer member including a cylindrical member and a spherical second tip and defining a cannulation extending in a direction from a proximal end of the outer member to a distal end of the outer member, the cannulation including a shoulder and a tapered portion disposed within the second tip and extending to a distalmost end of the outer member, wherein the inner member includes outer threads and the outer member includes inner threads configured to mesh with the outer threads on the inner member; and an instrument defining a pocket configured to receive the spherical second tip of the outer member, the handle being adjustable at a desired angle relative to the instrument when the spherical second tip of the outer member is disposed in the pocket and the first tip of the inner member is positioned in the cannulation spaced apart from the spherical second tip, wherein the first tip expands the spherical second tip radially outward without engaging the pocket such that the spherical second tip engages the pocket and locks the handle at the desired angle when the first tip is positioned in the cannulation in engagement with the spherical second tip, and wherein the engagement between the first tip and the second tip occurs inside the pocket.
