Surgical instruments and methods of use

A bushing for use with a drill, comprising a cannulation extending along a length of the bushing from a proximal end to a distal end, more than one flexible portion along the length, and at least one solid portion along the length, wherein each flexible portion is separated from one another by a solid portion.

A surgical system for the preparation of a bore hole in bone, comprising:na cannulated guide having a length between proximal and distal ends and a curved portion along at least a portion of the length;a drill or an implant inserter sized to pass through the cannulation of the cannulated guide; anda bushing having an outer diameter sized to be positioned within the cannulation of the cannulated guide and a cannulation extending along a length from a proximal end to a distal end sized to position the drill or implant inserter therethrough.

A method of centering a drill within a cannulation of a curved guide, the drill including a drilling tip at a distal end and a flexible portion positioned towards the distal end of the drill and proximal to the drilling tip, the method comprising the steps of:nobtaining the curved guide, the guide having a length between proximal and distal ends, the length defining a longitudinal axis of the guide, and a curved portion along at least a portion of the length and positioned towards a distal end of the guide, and the flexible instrument having a length between proximal and distal ends;obtaining a bushing having an outer diameter sized to be positioned within the cannulation of the curved guide and a cannulation extending along a length from a proximal end to a distal end sized to position the flexible instrument therethrough, the bushing including a flexible portion positioned towards the distal end of the bushing;directing the flexible portions of the bushing and the drill into the cannulation of the curved guide and through the curved portion of the curved guide, wherein the portion of the bushing passing through and beyond the curved portion of the curved guide maintains the drilling tip, passing through and beyond the curved portion of the curved guide, substantially coaxial with the longitudinal axis of the curved guide.

A kit, comprising:nat least one cannulated guide, the guide having a length between proximal and distal ends, the length defining a longitudinal axis of the guide, and a curved portion along at least a portion of the length;at least one drill or implant inserter having a length between proximal and distal ends and a flexible portion along at least a portion of the length; andat least one bushing having a cannulation extending along a length of the bushing from a proximal end to a distal end, at least one flexible portion along the length, and at least one solid portion along the length.
