Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the sketch map of mandibular angle bone cutting positioner embodiment of the present invention;
Fig. 2 is the front view that installs among Fig. 1;
Fig. 3 is the lateral plan that installs among Fig. 1;
Fig. 4 is the enlarged drawing of the length mark that installs among Fig. 1;
Fig. 5 is the sketch map of fixed structure among Fig. 1.
The specific embodiment
The present invention by fixed bar and sliding bar cooperation and combine length mark, realized the accurate location in the mandibular angle bone cutting operation.
As Figure 1-3, be the sketch map of an embodiment of mandibular angle bone cutting positioner of the present invention.This device comprises fixed bar 10, sliding bar 20 and fixed structure, and wherein fixed bar 20 is slidingly connected with sliding bar 20, and fixed structure is used for fixed bar 10 and sliding bar 20 relative fixed.
The end of first end of fixed bar 10 is provided with angle of mandible fixation hook 11, this angle of mandible fixation hook 11 expose sliding bar 20 first end the end (especially, this angle of mandible fixation hook 11 can be bent to form by the end of fixed bar 10 first ends), to catch on the edge of angle of mandible skeleton, prevent that this device is whole mobile.Be provided with handle hole 12 at first end of fixed bar 10 along the length direction of fixed bar 10, be provided with length mark 13 at second end of fixed bar 10.In the present embodiment, handle hole 12 is for being positioned at the intermediary strip of fixed bar hole, and along with sliding bar 20 ground slide, this handle hole 12 to small part is exposed the end of sliding bar 20 first ends.
One of them surface of sliding bar 20 is provided with chute 21, and fixed bar embeds above-mentioned chute 21, thus sliding bar 20 can with fixed bar 10 relative slips, realize the location.Above-mentioned chute is extended by the both sides (example of part only is shown in the way in whole or in part) of sliding bar 21 and is bent to form to fixed bar 10.
The end of sliding bar 20 first ends and the handle hole 12 of fixed bar 10 have constituted the operative position of bone-culting operation, can use the miniature right-angle bone drill to pass handle hole 12 and hole on mandibular bone in the end of being close to sliding bar 20 first ends.Along with the slip of sliding bar 20, can in the length range of handle hole 12, realize location adjustment.
For the further positioning accuracy that increases, the positioning port that can match in the shape of setting of the end of sliding bar 20 first ends and miniature right-angle bone drill drill bit, thus avoid slip when boring.In addition, also can a locating hole be set at sliding bar 20 first ends, this locating hole moves along with moving of sliding bar 20, and spacing hole and above-mentioned locating hole that miniature right-angle bone drill drill bit can pass on the fixed bar 10 carry out drilling operation.
Also be provided with strip fixing hole (not shown) on fixed bar 10, this strip fixing hole has the length identical with handle hole.Fixture comprises nut of being located on the sliding bar 20 32 and the bolt 31 that cooperates with this nut 32, and bolt 31 passes the strip fixing hole and cooperates (as shown in Figure 5) with nut 32.When bolt 31 was tightened, fixed bar 10 tightly touched with sliding bar 20, can not slide relatively; When bolt 31 unclamped, the frictional force between fixed bar 10 and the sliding bar 20 reduced, and can slide relatively.
Because face's skeleton of people is not an even curface, therefore in order to adapt to the surface configuration of face's skeleton, above-mentioned fixed bar 10 and sliding bar 20 can adopt the strip flexure strip (for example stainless steel substrates) less than 0.6 millimeter respectively, thereby make the integral body of this device bending fit to bone surface.
As shown in Figure 4, second end of fixed bar 10 is provided with length mark 13, and with the end of sliding bar 20 second ends as stoichiometric point, thereby realize quantitatively moving of sliding bar 20, accurately to locate.Above-mentioned length 13 labellings are along with the end that small part is exposed sliding bar 20 second ends that slides into of sliding bar.
Certainly, in actual applications, above-mentioned length mark also can be positioned at other positions of fixed bar 10, and a stoichiometric point is set on sliding bar 20, to realize the metering of movable length.In addition, also length mark can be located on the sliding bar 20, and on fixed bar 10, anchor point be set, can realize the metering of movable length equally.
In said apparatus, sliding bar 20 is not limited to mode shown in Figure 1 with the sliding connection structure of fixed bar 10, can realize that equally sliding bar 20 slides along the length direction of fixed bar, for example on fixed bar 10, chute is set, and sliding bar 20 is embedded above-mentioned chute.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
