Abstract
A cutter for cutting an implant is provided. The cutter includes a handle; a handle coupler coupled to the handle; a drill guide coupled to the handle coupler and including at least one window; a mill extending through the handle coupler and the drill guide and disposed to rotate freely therein; and a catch cup circumscribing the drill guide to maintain chips of the implant removed by the mill.
Claims20
A cutter for cutting an implant, comprising:
- a handle;
- a handle coupler for coupling to the handle;
- a drill guide distal to the handle coupler for coupling to the handle coupler and including at least one window;
- a mill for extending through the handle coupler and the drill guide and disposed to rotate freely therein;
- and
- a catch cup for circumscribing the drill guide to maintain chips of the implant removed by the mill and passed through the at least one window.

A cutter for cutting an implant, comprising:
- a handle coupler having an outside surface, proximal and distal end surfaces extending transversely to the outside surface, a central bore extending longitudinally from the proximal end surface to the distal end surface, and a threaded screw bore extending radially from the central bore to the outside surface of the handle coupler;
- a handle having a proximal gripping end and a distal connecting end having a screw-like connector, the screw-like connector engaging with the threaded screw bore and extending into the central bore of the handle coupler;
- a drill guide having an outside surface, a proximal mating end disposed within the central bore of the handle coupler and maintained therein by the screw-like connector of the handle, a distal engaging end having a cutout shaped to receive the implant, a longitudinally extending mill receipt bore extending from the mating end to the engaging end, a window extending radially from the mill receipt bore to the outside surface of the drill guide, and circumferential screw threads on the outside surface of the drill guide;
- a mill extending through the central bore of the handle coupler and into the mill receipt bore of the drill guide, the mill including a proximal connector having a distally facing stopping surface, a milling bit extending distally from the proximal connector to a distal cutting end, and a helical transport groove extending proximally from the distal cutting end to a stop;
- a catch cup circumscribing the drill guide, the catch cup including a proximal end abutting the distal end surface of the handle coupler, a distal end provided with inside threads engaging with the circumferential screw threads of the drill guide, and a longitudinal bore having a diameter greater than an outside diameter of the drill guide and extending from the inside threads to the proximal end of the catch cup;
- and
- a receiving cavity formed by the catch cup and drill guide.
