Abstract

The utility model relates to a multifunctional reset fixer for the fracture of skull, jaw and face, wherein, the both ends of a wire loop of a locking cap 4 are connected by a sliding-groove 7 and a plurality of sealed devices 1 are installed inside the wire loop. A draw bar 5 is connected with a tragus column 8 of the locking cap 4 by the sliding-groove 7; an adjustor 2 is arranged on the draw bar, both sides of which have forward and backward devices 3; a fixing nut 9 is arranged on a face fixed bar 6; a neck fixing bar 10 is connected with the locking cap 4 by the draw bar 5. The utility model is mainly used for resetting fixing for the fracture of skull, jaw and face, also for operation fixing of skull, jaw and face. The utility model overcomes the disadvantage of traditional treatment methods and has the advantages of high efficiency, flexible operation, various functions, and repetitious use.

Description

Multifunctional reset fixer for the fracture of skull, jaw and face

This utility model is that to be used for resetting of cranium, chin, facial bone folding fixing; Also can be used for cranium, chin, the postoperative fixed a kind of training medical apparatus and instruments that resets of face.

For a long time, cranium, chin, facial bone folding all adopt two kinds of methods of internal fixation and external fixation, also unite use sometimes.Internal fixation: promptly open reduction is fixed.Needs of patients bears the painful and heavy financial burden of huge operation, and leaves over down facial deformity in various degree.External fixation: fix with the ligation of the capable list chin of stainless steel silk, Kirschner wire, these all only are applicable to general simple fractures.U.S. Federspeil invention in 1934 is made " gypsum cap " at head and is imbedded steel wire betwixt, carry out chin bone fracture on the external traction therapeutic, use till today always, because of complicated operation, be difficult for grasping, after plaster fixation, bring a lot of miseries to the patient, can not adjust the size and Orientation of pull strength as required, can not carry out multi-faceted reset fixing.GeorgiadeShi in 1966 designs " external fixer of sunshading board haloing formula " and need pierce a lot of bone thread pins on skull, aluminum or stainless steel silk support are installed on spicule again, both increase the misery of operation, may cause the damage of cerebral dura mater and venous sinus again.More than external fixture all be difficult to solve complicated fracture, the Liao Dynasty does not see the ideal medical apparatus and instruments of this respect both at home and abroad till the present as yet.

The purpose of this utility model is: it has overcome the various shortcoming of above-mentioned various " external fixation " method, can replace " internal fixation " art, and it is painful to make most patients avoid operation, has opened up the new situation that cranium, chin, facial bone folding are treated.

This utility model is to realize like this, primary structure is made up of locking cap (4) and arcual draw bar (5), locking cap (4) is the quoit of an aluminum, two ends are connected by sliding tray (7), but transfer size, be contained in the quoit by several driving fit devices (1), the scalable degree of tightness so just can be regulated big or small degree of tightness and freely gets and wear according to patient's capitiform size and difformity.Draw bar (5) is the arc aluminium alloy hollow pipe of one one diameter 0.5Cm, be connected with sliding tray (7) on the tragus post (8) of locking cap (4), it can be from the crown to the arc rotation of 180 ° in face portion work, also can be elastic, get as required and wear, on draw bar (5), dispose several actuators that does not wait (2), it both can slide along about draw bar (5), also but the rotation of 360 degree is done in the original place, the both wings of actuator (2) have advance and retreat device (3), it can before and after advance and retreat, also can unloading, (9) be hold-doun nut on facial fixed bar (6), fixed bar (10) is connected with locking cap (4) by draw bar (5).

This utility model has overcome the shortcoming of current various Therapeutic Method, has reached effect height, damage little, flexible operation, diverse in function, has got and wear conveniently, can repeatedly use.

Fig. 1 is at overall structure figure of the present utility model;

Fig. 2-4 is respectively among Fig. 11,2,3, the structure chart of parts.

As shown in Figure 1, so designed locking cap and draw bar two parts, be that body is special according to cranium chin, facial bone complex structure at this utility model, undertake major physiological functions such as breathing, digestion, language again, when fracture takes place, can not take common treatment of fractures method.Put on interior pad for earlier during use patient's head; put on locking cap (4), adjusting driving fit device (1) and sliding tray (7) again and make it size and looseness appropriateness; install again " draw bar (5) and actuator (2); they are adjusted to the position that needs in fracture; under aseptic condition; cut and be about otch (then need not otch) that 0.5-1Cm the is deep to periosteum soft tissue around protecting with otoscope; be connected with advance and retreat devices (3) again as open fracture, regulate push away, the size and Orientation of pulling force can reach the fixedly purpose that resets.
