Abstract
Abstract A drill assembly includes a handle carrying a mount for a pneumatic drill motor, and an elongated tubular support enclosing an extended motor shaft which carries a drill bit chuck projecting from the end of that support. The drill assembly coacts with a drill guide assembly including an elongated tubular guide for receiving the tubular support in sliding relation, and having a rotary bearing at its lower end for rotationally supporting the drill bit. The lower end face is concave to enable seating on the prosthesis tip to be drilled. The drill guide assembly includes an offset handle and a stop clamp and depth gauge for coaction with the drill assembly handle to control the depth of drilling.

Apparatus as set forth in claim 1 said drill including bearing means disposed within the lower end of said tubular support for rotationally supporting the lower end of said drive shaft; said drill guide assembly including bearing means disposed in the lower end thereof for rotationally supporting a drill bit mounted in said drill chuck means.
Claim 4
Dependent Claim
80 words
Apparatus as set forth in claim 1 said drill guide including a support shaft mounted in parallel offset relation therewith; a stop member mounted in sliding relation on said support shaft and disposed for interfering relation with said drill assembly, said stop member having clamp means for securing said member in selected position on said shaft; a depth gauge rotatably mounted on said shaft and disposed for overlying relation with said stop member and interfering relation with said drill assembly.
Claim 5
Dependent Claim
53 words
Apparatus as set forth in claim 3 said drill assembly handle means including a support handle extending laterally from said elongated drill support; said drill guide including a support handle extending laterally from said support shaft; said support handles enabling independent manual support and guiding of said drill assembly and said drill guide.
Claim 6
Dependent Claim
77 words
Apparatus as set forth in claim 1 said drill guide including an adjustable stop member mounted for movement parallel to the longitudinal axis of said drill guide and disposed for interfering relation with said drill assembly, said stop member having means for securing said member in a selected position; a depth gauge mounted in overlying relation with said stop member, being movable relative to said stop member for selective interfering and non-interfering relation with said drill assembly.
Claim 7
Dependent Claim
39 words
Apparatus as set forth in claim 1 one end of said drill guide, associated with the drill chuck end of said tubular support, having means for locating said one drill guide end relative to an object to be drilled.
Claim 8
Dependent Claim
133 words
A manual drilling method comprising the steps fabricating a drill assembly to include an elongated tubular support, a rotary drill motor mounted at one end of said support, an elongated drive shaft coupled at one end to said motor and rotatably supported in said tubular support, and a drill chuck nonrotatably mounted at the other end of said drive shaft; supporting said drill assembly in a drill guide dimensioned to receive and guide said tubular support for relative rotational and axial movement; providing fixed handle means on each of said drill guide and said drill assembly to enable the manual guiding of each assembly; and providing coacting interference members on said drill guide and said drill assembly for limiting axial movement of said drill assembly toward said one end of said drill guide.
Claim 9
Dependent Claim
133 words
A manual drilling method comprising the steps fabricating a drill assembly to include an elongated tubular support, a rotary drill motor mounted at one end of said support, an elongated drive shaft coupled at one end to said motor and rotatably supported in said tubular support, and a drill chuck nonrotatably mounted at the other end of said drive shaft; supporting said drill assembly in a drill guide dimensioned to receive and guide said tubular support for relative rotational and axial movement; providing fixed handle means on each of said drill guide and said drill assembly to enable the manual guiding of each assembly; and providing coacting interference members on said drill guide and said drill assembly for limiting axial movement of said drill assembly toward said one end of said drill guide.
