Abstract
The utility model discloses a two-dimension jaw bone traction apparatus and comprises a threaded rod, an upper mounting plate and a lower mounting plate. The apparatus is characterized in that an arc-shaped sliding rod is bending to one side; the sliding rod and the threaded rod are not in the same plane; the lower mounting plate has a connecting end both on right and left center, wherein one connecting end is welded to the sliding rod, and the other connecting end is connected to the bottom of the threaded rod by a spherical hinge; the upper mounting plate is wrapped and connected to the sliding rod and the threaded rod, and then engaged with the threads of a threaded rod. The function of the utility model lies in that reconstruction and traction are implemented to the irregular shape bones such as jaw bone in two dimensions. Then, the ubiety of a new alveolar and a jaw dental arch is accordant with the law of human natural, thus makes denture recovery easily on next stage.
Description
Technical field
This utility model relates to a kind of jawbone orthopedic instruments, particularly discloses a kind of jawbone two dimension traction apparatus.
Background technology
Jaw bone tractor on the domestic and international market is folk prescription to bone tractor at present, can only finish the bone traction of one dimension direction exactly.Not only can not draw and reconstruct the jawbone profile profile that is similar to nature such as nasolabial fold, chin labial groove, outer oblique ridge, and the new alveolar process that traction reconstructs is undesirable usually with the position relation to the jaw dental arch, for the artificial tooth reparation in later stage brings difficulty.
Summary of the invention
The purpose of this utility model is to solve defective of the prior art, and a kind of jawbone two dimension traction apparatus that can realize the traction of two-dimensional directional bone is provided.
This utility model is achieved in that a kind of jawbone two dimension traction apparatus, comprises threaded rod, and the pitch of thread is 0.4 millimeter, upper fixed plate, below fixing head.It is characterized in that: also comprise sliding bar, described sliding bar camber is to a lateral bending song, and sliding bar and threaded rod be not in same plane; Respectively there is a link both sides, center of described below fixing head, and one of them link links to each other with the bottom of sliding bar, and another link links to each other with movable connection structure with the bottom of threaded rod; Described upper fixed sleeve-board is connected on sliding bar and the threaded rod, and joins with the threaded rod screw thread.
According to above-mentioned jawbone two dimension traction apparatus, it is characterized in that: the movable connection structure of described threaded rod and below fixing head is a spherical hinge structure, and the connected mode of described sliding bar bottom and below fixing head connects for weldering.
Jawbone two dimension traction apparatus according to above-mentioned is characterized in that: also comprise the additional fastening plate, the top weldering of described additional fastening plate and sliding bar connects.
The beneficial effects of the utility model are: can carry out two-dimensional directional to the bone of irregular forms such as jawbone and draw reconstruction, make traction new alveolar process that reconstructs and the rule that the position relation of jaw dental arch is met human body natural, make things convenient for the artificial tooth reparation in later stage.
Description of drawings
Fig. 1 is that this utility model is faced structural representation.
Fig. 2 is this utility model schematic side view.
Among the figure: 1, below fixing head; 2, upper fixed plate; 3, threaded rod; 4, sliding bar; 5, additional fastening plate; 6, spherical hinge structure.
The specific embodiment
According to Fig. 1, Fig. 2, this utility model comprises threaded rod 3, sliding bar 4, upper fixed plate 2, below fixing head 1, additional fastening plate 5.There are two links the both sides, center of below fixing head 1, and threaded rod 3 bottoms are connected with a link of below fixing head 1 with spherical hinge structure 6; Sliding bar 4 is to a lateral bending song, and with threaded rod 3 not in same plane, sliding bar 4 is crooked to the inside in this example, and its degree of crook also can impose external force according to the jawbone shape before use and finely tune, and is advisable but regulating degree should not influence the slip of upper fixed plate 2; Another link weldering of sliding bar 4 bottoms and below fixing head 1 connects; Sliding bar 4 tops and 5 welderings of additional fastening plate connect.Upper fixed plate 2 is socketed on sliding bar 4 and the threaded rod 3, and joins with threaded rod 3 screw threads.
In use, drive upper fixed plate 2 by rotation threaded rod 3 and move,, move in the radian direction traction of the traction lower edge of sliding bar 4 sliding bar 4 because upper fixed plate 2 is socketed on the sliding bar 4.This utility model is when traction is initial, upper fixed plate 2 is near the bottom of threaded rod 3 and sliding bar 4, threaded rod 3 long axis directions are the bone surface tangential direction before the movable bone BOB(beginning of block) traction, threaded rod 3 tops and sliding bar 4 top separating distance maximums, the collinear angle that threaded rod 3 and sliding bar 4 two ends are linked to be, deputy activity bone piece can the crooked maximum radians that moves under this utility model guiding.In traction, upper fixed plate 2 is drawn close to threaded rod 3 and sliding bar 4 tops gradually, and threaded rod 3 tops and sliding bar 4 vertical separating distances dwindle gradually.When upper fixed plate 2 was close to threaded rod 3 tops and sliding bar 4 tops, threaded rod 3 was zero with the collinear angle that sliding bar 4 two ends are linked to be, and this moment, traction finished.
Claims (3)
