Abstract

Claims (32)

1. A navigation-guided surgery fixation (NGSF) system, comprising:

a. a fixation member for fixating an intraoral surgical guide, the fixation member comprising:

i. a shank portion; and

ii. a shaft portion, the shaft portion extending out from an end portion of the shank portion, and wherein the shank portion has a diameter greater than that of the shaft portion;

b. a sleeve member, wherein the sleeve member comprises a through-hole substantially the same size of the shank portion and configured to receive the shank portion therein;

c. a fixation drill key, the fixation drill key comprising a through-hole, wherein at least a portion of the fixation drill key is configured to be received within the through-hole of the sleeve member; and

d. a fixation drill bit, wherein at least a portion of the fixation drill bit is configured to be received through the through-hole of the fixation drill key.

2. The system of claim 1 , wherein the fixation member comprises at least one of a fixation pin or a fixation screw.

3. The system of claim 1 , wherein the fixation member further comprises:

a. a head portion at a proximal end of the fixation member;

b. a baseplate portion spaced apart from the head portion;

c. a spacer portion disposed between the head portion and the baseplate portion;

d. a tip portion at a distal end of the shaft portion; and

wherein the shank portion extends out at its proximal end from a side of the baseplate opposite that of the spacer.

4. The system of claim 1 , wherein the sleeve member further comprises:

a. a sleeve body; and

b. a sleeve baseplate.

5. The system of claim 4 , wherein the sleeve body is configured to fit within a fixation guide hole of the intraoral surgical guide.

6. The system of claim 1 , wherein the fixation drill key further comprises:

a. a drill key body;

b. a drill key arm extending out perpendicularly from a side of the drill key body; and

c. a drill key shank extending from a surface of the drill key body and substantially perpendicular to the drill key arm, and wherein the through-hole of the fixation drill key extends through both the drill key body and the drill key shank.

7. The system of claim 1 , wherein the fixation drill bit comprises:

a. a drill bit shank; and

b. a drill bit, the drill bit extending out from the drill bit shank, wherein the drill bit portion is configured to be at least partially received through the sleeve member through-hole and the fixation drill key through-hole.

8. A navigation-guided surgery fixation (NGSF) kit, comprising:

a. a plurality of fixation members, each comprising a shank portion and a shaft portion extending out from an end portion of the shank portion, wherein the shank portions of all of the plurality of fixation members have a same diameter which is greater than a diameter of any one of the shaft portions of the plurality of fixation members, and wherein the shaft portions of one or more of the plurality of fixation members have differing diameters from one another; and

b. a sleeve member, wherein the sleeve member comprises a through-hole having a diameter substantially the same as that of the shank portion of the plurality of fixation members and is configured to receive the shank portion of the plurality of fixation members therein.

9. The kit of claim 8 , wherein the fixation member comprises at least one of a fixation pin or a fixation screw.

10. The kit of claim 8 , further comprising:

a. a fixation drill key, the fixation drill key comprising a through-hole, wherein at least a portion of the fixation drill key is configured to be received within the through-hole of the sleeve member; and

b. a fixation drill bit, wherein at least a portion of the fixation drill bit is configured to be received through the through-hole of the fixation drill key.
