Abstract
An apparatus for bone milling includes a housing defining a first opening, a second opening opposite the first opening, and a linear passage from the first opening to the second opening. The linear passage has a first surface with third opening there through and a second surface transverse to the first surface. A rotatable cutting member is insertable through the third opening to partially block the linear passage. The rotatable cutting member is positioned at a distance from the second surface of the linear passage corresponding to a predetermined bone chip size.
Claims20
An apparatus for bone milling, comprising:
- a housing defining a first opening, a second opening opposite the first opening, and a linear passage from the first opening to the second opening, the linear passage having a first surface with third opening therethrough and a second surface transverse to the first surface;
- a rotatable cutting member insertable through the third opening to partially block the linear passage, the rotatable cutting member being positioned at a distance from the second surface of the linear passage, the distance defining a predetermined bone chip size;
- an actuator element having a first end and a second end opposite the first end, wherein the first end is removably coupled to the housing;
- and
- an actuator cap removably coupleable with the second end of the actuator element, the actuator cap defining an adapter receiving impression.
An apparatus for bone milling engageable with a drive source having a tool-receiving portion, comprising:
- a housing defining a first opening, a second opening opposite the first opening, and a linear passage from the first opening to the second opening;
- a single-stage milling assembly consisting of a rotatable cutting member traversing at least a portion of the linear passage;
- an actuator element defining a first end, a second end opposite the first end and a channel extending from the first end to the second end;
- an actuator cap removably coupleable with the second end of the actuator element, the actuator cap defining an adapter receiving impression;
- and
- an adapter defining a first end and a second end, wherein the first end is positionable in the adapter receiving impression of the actuator cap and the second end is engageable with the tool-receiving portion of a drive source.
A method for milling bone, comprising the steps of:
- inserting bone to be milled into a bone milling apparatus, the apparatus being comprised of:
- a housing defining a first opening, a second opening opposite the first opening, and a linear passage from the first opening to the second opening, the linear passage having a first surface with third opening there through and a second surface transverse to the first surface;
- and
- a rotatable cutting member defining a cutting edge, the rotatable cutting member being insertable through the third opening to partially block the linear passage, the rotatable cutting member further being positioned at a distance from the second surface of the linear passage corresponding to a predetermined bone chip size;
- an actuator element defining a first end, a second end opposite the first end and a channel extending from the first end to the second end;
- an actuator cap removably coupleable with the second end of the actuator element, the actuator cap defining an adapter receiving impression;
- and
- an adapter defining a first end and a second end, wherein the first end is positionable in the adapter receiving impression of the actuator cap;
- a plunger;
- and
- a milled material receptacle removably coupled to the second opening;
- engaging the second end of the adapter with a drive source;
- placing the plunger in the first opening of the apparatus to force the bone towards the rotatable cutting member,
- operating the drive source to rotate the rotatable cutting member, thereby milling the bone, and
- collecting the milled material in the milled material receptacle.
