Abstract

The invention provides a mandibular angle bone cutting localizer medical appliance used for the beauty treatment, which includes a 'U'-shape pole and a bone cutting line fixing stretcher on the two poles slidingly covered joint on the 'U'-shape pole. The bottom curve reach of the 'U'-shape pole deflects toward the axial direction of the same plane for the two poles of the 'U'-shape pole to form the mandibular angle fixation hook. The invention solves the difficulties which can not position precisely in the mandibular angle bone cutting surgery, although the present surgery can correctly ensure the safe bone cutting line, due to the same line or in parallel of the cutting part and the sight of the doctor in the surgery, it is difficult to ensure the precise cutting part in advance, only depending on the experience of the doctor, so the error rate is very large, which causes great pain to the patients, even appears the irretrievable phase. Using the mandibular angle bone cutting localizer, can change the experience judgement and the subjective judgement depending on the doctor in the past, which makes the mandibular angle bone cutting risk greatly small.

Description

Localizer of mandibular angle osteotomy

Technical field

The invention belongs to technical field of medical instruments, relate in particular to a kind of beauty treatment medical apparatus and instruments.

Background technology

The mankind have entered since the twentieth century, and the medical cosmetology skill is advanced by leaps and bounds, and along with the continuous pursuit of people to U.S., the cosmetic surgery technology is maked rapid progress, and has removed the hardship of slight illness for a large amount of patients.In aesthetic surgery, there is a class patient (especially women) face shape bigger, the side sees and is male's angle of mandible, and lack soft, smooth profile, they generally are the angle of mandible hypertrophys, and how with the masseter plumpness, cosmetic surgery requires the shaping of row angle of mandible.Treatment is based on mandibular angle bone cutting or the excision of companion's part masseter.The difficulty of the loose osteotomy maximum of angle of mandible is appearing of angle of mandible and locatees.

The method of operation mainly be divided into mouthful outer approach and mouthful in two kinds of methods of approach, extra-oral method appears angle of mandible and the location is easier to, clear visual field, but the part is left the operative incision cicatrix that appears and regretted by patient and doctor.The intraoral method visual field is less and dark, appear and the location is not easy, but can solve the sorry of operative incision cicatrix, use intraoral method at present mostly, carry out the X-ray film developing before patient's art earlier, according to Kamishi osteotomy line design method, at lower jaw surface fault X-ray sheet or on the X-ray sheet of mandibular bone side position, marking the vertical line of mandibular bone ascending branch leading edge and the equality line of biteplane and the line of inferior border of mandible and ascending branch trailing edge intersection point is safe osteotomy line.But in actual operation, because the intraoral method visual field is unclear, angle of mandible is parallel with the sight line of operative doctor or point-blank, this makes the general position of just rule of thumb judging institute's amputation of doctor, determines the osteotomy line, makes mistakes easily, even depart from the very big position of safe osteotomy line, do not reach the purpose of operation, caused misery to patient on the contrary, even the situation that can't retrieve.

Summary of the invention

The purpose of this invention is to provide a kind of localizer of mandibular angle osteotomy that allows the beauty treatment doctor in operation, stretch into the required amputation of accurate in locating mandibular bone position in the operative incision of patient's mouth easily.

Design of the present invention is: become buckle " U " shape bar as the parts of determining localizer and angle of mandible relative position relation with a bottom, reuse a locating rod and " U " shape bar slip socket straight or the band arcuation, and the distance variableization of the hook portion of " U " shape bar of locating rod and buckle, thereby determine as the following cutter position that excises angle of mandible.Prevent in the exemplary fuzzy wound of flesh and blood the problem that can't accurately regulate incision site.

Structure of the present invention is: comprise " U " shape bar 1, the width of the bottom bend section of " U " shape bar 1 is less than the width of upper end two bars, and " U " shape bar 1 bottom bend section becomes angle of mandible fixation hook 4 to the planar axial direction deviation in two bar places of " U " shape bar 1, angle of mandible fixation hook 4 planes are 80-90 degree with the angle of two bars of " U " shape bar 1, slip socket osteotomy line location lever 2 on 1 liang of bar of " U " shape bar.Osteotomy line location lever 2 is in line or protrudes camber line down to the direction of angle of mandible fixation hook 4.

The present invention structure is also according to the size at patient's angle of mandible amputation position, the one or more osteotomy width of the socket positioning pipe 3 that can on two bars of " U " shape bar 1 between the lever 2 of angle of mandible fixation hook 4 and osteotomy line location, slide respectively, thus the size and the arc shape at amputation position changed.In order to reach this purpose, osteotomy width positioning pipe 3 can establish pipe range be respectively 1mm, 2mm, 5mm several, according to the size and the arc shape at the position of amputation, at U " be socketed into required shape respectively on two bars of shape bar 1.According to people's physiological feature, distance generally is made as 18-22mm between two bars of " U " shape bar 1, and the far-end of angle of mandible fixation hook (4) (away from the planar end in 1 liang of bar place of " U " shape bar) is 10-15mm with the planar distance in two bar places of " U " shape bar 1.For making things convenient for operative doctor can well observe amputation position and easy to use in operation process, two bars, one end of " U " shape bar 1 is a localizer free-end 4, and the other end is a localizer handheld terminal 5, and localizer free-end 4 is shorter than localizer handheld terminal 5.

In the beauty treatment clinical practice, patient to the angle of mandible hypertrophy implements the mandibular angle bone cutting art, contrast X-ray sheet is according to Kamishi osteotomy line design method before the art, determine the position size of required amputation, arc shape, accurately locate, mark the safe osteotomy line of mandibular bone, select and assemble localizer of mandibular angle osteotomy according to these data then.Operation method: operation is in general anesthesia or strengthen under the local anaesthesia and carry out: 1, otch and peeling off: cut mucosa, submucous tissue and periosteum in cheek gum bottom of trench instruction from the 2nd premolars to upper jaw tuberosity trailing edge, peel off to the back lower place along surface of bone with detacher and appear angle of mandible.Locate in attached of lower jaw edge part strip off masseter, when lower jaw is peeled off forward, reach the 2nd and grind one's teeth in sleep when locating.With localizer of mandibular angle osteotomy but go in the otch, with 2 jiaos on angle of mandible fixation hook 4 hook lower jaws, grind a bone groove with splitting brill or curcumbitate bistrique along osteotomy line location lever 2 earlier, take out localizer of mandibular angle osteotomy, then with goose saw with the angle of mandible amputation, then with bistrique with osteotomy after wound base polishing level and smooth.

Advantage of the present invention: having solved in beauty treatment in the especially mandibular angle bone cutting operation can a pinpoint difficult problem, though can accurately determine safe osteotomy line before the art, but in the art because amputation position is on the parallel or same straight line with the sight line of operative doctor, almost be difficult in the accurate amputation in the position that pre-determines, judge with doctor's experience entirely, error rate is very big, and this has just caused patient painful greatly, even irremediable situation occurred.Use localizer of mandibular angle osteotomy, the experience that changes doctor's past is judged, subjective judgment.Mandibular angle bone cutting art risk is reduced greatly, almost nil.
