Abstract
This utility model discloses a rectifier for restituting the fractured zygoma complex, and it is composed of forehead anchorage, track bound, sliding orientation ruler, face bow and ear rod. On the face bow, two sliding orientation rulers are installed; one end of the forehead anchorage is the silastic anchorage, and the other is the expansion rod, which is connected with the adjustable locking device; what is connected with the locking device is the upright column which is joined to the face bow vertically. This utility model with a simple structure is easy to use and may help to adjust bone blocks accurately, preventing the deformed asymmetric face and improving the treatment effectiveness.
Description
Technical field
This utility model belongs to the apparatus of cranium jaw surgery, more specifically relates to a kind of cheekbone complex fracture rectifier that quantitatively resets, and calibrates in the auxiliary and jaw face beauty treatment orthopaedy of the special practical viscerocranium reduction of the fracture in addition.The sterilization that carries out disinfection of the operating theater instruments sterilization of its available routine in order to using, can be instructed the accuracy of the reduction of the fracture in the art in operating room, prevent the asymmetric deformity of face, improves therapeutic effect.
Background technology
Though CT and three dimensional CT have significantly improved the accuracy rate of cheekbone complex fracture, computer rapid shaping technique sham operated moves sclerite and can predict postoperative effect, but the anatomical reduction of fracture site recovers profile and function in art, still has very big difficulty.Fialkov (1992) is used to instruct complicated craniofacial region reconstruction with stereotactic system, he has designed a three-dimensional positioning head frame, by both sides external auditory meatus and prefabricated jaw plate maintenance, the headstock and the labelling pin that rely on the resistance of X line to penetrate are done the preceding quantitative measurement of art, wear the headstock in the art, realize quantitative mobile bone piece by positioning needle.But it is combined, and fracture of maxillary jaw plane is destroyed, the patient of limitation of mouth opening and infant should not use.He Dongmei (2004) has reported the design of three-dimensional face bow and the application in fracture of zygomatic bone resets thereof, be characterized in that with the nose holder be support, be used to observe the cheekbone symmetry and estimate postoperative effect, but the patient who is combined fracture of nasal bone is difficult to use, and can not quantize.Along with development of human society, the sickness rate of wound constantly rises, and Sastry report oral and maxillofacial trauma accounts for 34% of whole body wound, and cheekbone, cheekbone complex fracture account for the first place of midfacial fracture.Handle at present cheekbone complex fracture, adopt usually that the doctor estimates fracture anatomical reduction in the art, recover external form and function, but often be difficult to reach the purpose that accurately well resets.
Orthognathic surgery will have odd-shaped bones of facial cranium to recover its normal anatomic form with operating method, yet the spatial displacement of lopsided jawbone or bone grafting moulds profile again in operation, these were entirely with the experiential operating of operator in the past, yet surgical experience is to be difficult to quantizedly, and same position operator may successively be operated all and there are differences.Originally orthognathic surgery includes cosmetic purpose, but because no reference value quantizes operation process, so be difficult to satisfy by patient's beauty treatment requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of cheekbone complex fracture rectifier that quantitatively resets, and simple in structure, easy to use, the bone block correction is accurate, has prevented the asymmetric deformity of face, has improved therapeutic effect.
Determine the error effect postoperative effect that sclerite resets in order to solve only to detect by an unaided eye in the art with the doctor, developed the cheekbone complex fracture rectifier that quantitatively resets, its feature is that ears masthead end extended line is on Frankfortplane, with nearly middle overlapping theoretic " 0 " point that promptly formed of sagittal plane joint, determined the symmetry of " 0 " some back according to image theory, the height of contour reduction of Ipsilateral face jaw is instructed in the range finding of promptly available strong side slip positioning rule; During bilateral cheekbone complex fracture, can reset with reference to the measurement average of normal population; If the facebow of rectifier is moved on frontal axis, can three-dimensional quantitative mobile sclerite reduction.And can be used for the evaluation of postoperative face shape bulging symmetry dough-making powder shape width.
In order to achieve the above object, this utility model adopts following technical measures:
A kind of cheekbone complex fracture rectifier that quantitatively resets, it is made of volume holder, rail limit, slip positioning rule, facebow and ear bar, it is characterized in that: two slip positioning rules are housed on facebow, end at E Tuo is equipped with the silicone rubber holder, the other end is equipped with expansion link, expansion link links to each other with adjustable lock knot device, and adjustable lock knot device links to each other with column, and column links to each other with facebow is vertical.
People's head is considered as spheroid, left-right symmetric, coordination up and down.Ears masthead end extended line and head median sagittal plane joint be overlapping promptly to have formed " 0 " point on the facebow.Determined after " 0 " point, can record strong side range finding and instruct Ipsilateral to reset according to the symmetry of image theory.This utility model is provided with E Tuo and places forehead (surface of bone), and ears bar end places external auditory canal opening, facebow can be limited on the parallel plane of Frankfort plane, and facebow can obtain stable supported at three point.The slip positioning rule can be made the sphere operating measurement on facebow.Facebow " 0 " some both sides respectively are 90 °, set 22-32 ° of positioning rule and measure the prominent point of zygomatic arch, set 45-55 ° of positioning rule and measure the prominent point of cheekbone.Measuring average through 40 (each 20 of men and women) adults is Ar-zm (facebow lower edge-zygomaxillary point) male left and right sides average 32.1/31.2mm, the women is 35.2/34.9mm, Ar-zy (facebow lower edge-zygion) male left and right sides average is 11.1/11.5mm, and the women is 13.4/14.2mm.Measured value novel shark bone bulging more is high more, and measured value the DAGU bulging is low more more.When positioning rule was measured, its terminal contact skin surface then put injection needle at the positioning rule end if hinder the back soft tissue swelling, thrusts skin and arrives at surface of bone, and it is more accurate to find range, good positioning effect.
This utility model compared with prior art has the following advantages and effect:
1, this instrument is used for clinical side cheekbone complex fracture with the reference of strong side range finding as the Ipsilateral reduction of the fracture; Bilateral fracture person can be with the Ar-zy that is surveyed, and the Ar-zm average is as the reference of the reduction of the fracture; Also can be used for upper jaw bone, the odd-shaped reduction due to socket of the eye bone or other causes of disease is proofreaied and correct the surface of bone height and is reached lateral symmetry.
2, when fracture operation resets, desire to make the bone piece that resets accurately to locate, meet soft tissue swelling clinically then at the terminal cover of positioning rule one injection needle, it is more accurate to thrust surface of bone, range finding that skin arrives at, obtains advantages of good positioning effect.
3, the side cheekbone complex fracture operation proof that resets in clinical practice, this rectifier can the quantitative correction reduction of the fracture, and be very important to recovering prominent point of profile symmetry and appearance harmony; And have economy, a simple, convenient plurality of advantages such as be suitable for.
