Description
This utility model relates to a kind of jawbone orthopedic instruments, a kind of jaw bone tractor.
As everyone knows, face jaw cosmetic surgery complexity, the treatment difficulty is big, for reaching good jawbone shaping effect, is scheme preferably with jaw bone tractor as the assistant orthopedic apparatus, as application number is a kind of orthopedic instruments 95200175.6 Chinese utility model patent " a kind of jawbone tractive extender " promptly discloses: it comprises tractive extender and holder, the tractive extender is by the adjustment screw rod through central authorities, before, rear slider and yardstick slide bar are formed, before, rear slider is carved with positive hour hands and counter-clockwise female thread respectively and screws in adjustment screw rod through central authorities by positive hour hands and inhour respectively, on, before following yardstick slide bar runs through, on the rear slider, following slide opening, holder are that the bushing type screw rod and the nut that have the Kirschner wire fixture are formed.But the structure of this jawbone tractive extender is more complicated also, fixing, all inconvenience to some extent of adjusting.
The purpose of this utility model just is to provide at above-mentioned prior art present situation a kind of simple in structure, secured adjusted jaw bone tractor easily.
The purpose of this utility model is achieved in that jaw bone tractor includes screwed pipe, screw rod, sleeve pipe and screw rod rotation regulating mechanism, screw rod is positioned at sleeve pipe, its end passes sleeve bottom and fixes with the screw rod rotation regulating mechanism, the screwed pipe plug is connected in sleeve pipe and with screw flight, its head is fixed with screw frame and thimble, and sleeve outer wall then is fixed with corresponding screw frame.Described rotation regulating mechanism is good with universal adjustment mechanism, comprise screw bolt seat with its adjusting rod that is connected by gimbal structure, wherein screw bolt seat and the above-mentioned screw rod end that passes outside the sleeve bottom fix.
This utility model is fixed by the screw frame on screwed pipe and the sleeve pipe respectively with tapping screw in two sides up and down of patient's jawbone section, and is fixed as adnexa with the thimble on the screwed pipe in use.Compared with prior art, this utility model convenient fixing, the length adjustment freedom has stable stretching resistance, thereby more helps the carrying out of performing the operation, thereby reaches effectively, therapy rehabilitation effect efficiently.
Description of drawings:
Fig. 1 is the stereoscopic sketch map of this utility model embodiment.
Fig. 2 is the structural representation (broken section) of this utility model embodiment.
Fig. 3 is the partial enlarged drawing of Fig. 2
Fig. 4 is the A-A cutaway view of Fig. 3.
Embodiment is described in further detail this utility model below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, jaw bone tractor comprises screwed pipe (1), screw rod (5), sleeve pipe (2) reaches by screw bolt seat (3), the screw rod rotation regulating mechanism that adjusting rod (4) constitutes, screw rod (5) is positioned at sleeve pipe (2), its end passes sleeve pipe (2) bottom and fixing by screw bolt seat (3), thereby screw rod (5) is limited in sleeve pipe (2) bottom, spinning movement can only be arranged, screwed pipe (1) plug is threaded in sleeve pipe (2) and with screw rod (5), its head is fixed (can directly weld) screw frame (11) and thimble (12), sleeve pipe (2) outer wall then fixing (can directly weld) has corresponding screw frame (21), adjusting rod (4) is connected by gimbal structure with screw bolt seat (3), as Fig. 3, shown in Figure 4.
During use, turn adjusting rod (4) rotates screw bolt seat (3) and screw rod (5) simultaneously, because relative motion, screwed pipe (1) can stretch by relative sleeve pipe (2), thereby regulates length.
This utility model is good to adopt the fabulous titanium alloy material of human body intermiscibility.
