The patient's economic burden as well as the pain in surgical treatment can be reduced.

Description

A kind of maxillofacial fracture reduction fixture device

Technical field

This utility model relates to a kind of maxillofacial fracture reduction fixture device.Now belong to technical field of medical instruments.

Background technology

Maxillofacial fracture is a case common in the medical treatment, is to make complicated gypsum cap to the non-surgical treatment of fracture of maxillary, or squeezes into peg on skull, and upper jaw bone is carried out reduction by traction.Use inconvenience because of this method, pull strength often acts on the labial teeth district, thereby curative effect is not good enough, and the patient of correct facial swelling can not use in early days.So over surplus in the of nearly ten year, Chinese scholars advocates upper jaw bone or midfacial fracture more, the internal fixation method of adopt big otch, many otch, extensively peeling off is treated.Clinical practice proves, this kind surgical technic complexity, and the patient damages excessive, and economy and mental burden are overweight.

Summary of the invention

This utility model provides a kind of Therapeutic Method simple for addressing the above problem, and patient is not caused special damage, the maxillofacial fracture reduction fixture device that can treat the patient as early as possible after wound.

This kind maxillofacial fracture reduction fixture device is that following method realizes.It by make with leather, velcro is fixed, the head cap of scalable degree of tightness, form with metal vertical support frame, preceding tilted supporter, cheekbone traction frame, mandibular arch, maxillary, upper jaw pallet.The pallet fixation clamp is arranged on maxillary.The elastic rubber tube that uses when also having auxiliary belt loop and traction fracture in addition.Utilize the elasticity of metal and rubber tube, to jawbone draw or on push away, to reach the purpose that resets.

The utility model has the advantages that: using method is easy, and strong fast to the reduction of the fracture, curative effect is reliable.Both can reduce patient's economy expenditure, also reduce the painful and damage that operation causes patient.Correct facial swelling patient can use at any time.Can delay treatment opportunity.

The specific embodiment

Further describe concrete structure of the present utility model below in conjunction with accompanying drawing.

This utility model maxillofacial fracture reduction fixture device has the fixing also head cap 1 of scalable degree of tightness of band velcro, and head cap 1 comprises heading tape and hatband composition, and there is arc fixation steel plate 2 front of hatband.There are vertical support frame 3, preceding tilted supporter 4 in the both sides that are connected with head cap, and the middle and upper part of two stands and cheekbone traction frame 5 are connected and fixed, and lower end and mandibular arch 6 are connected and fixed.Maxillary 7 moving up and down is installed between tilted supporter before both sides, and preceding tilted supporter 4 sidepieces have dentation draw-in groove 16, and on the head end cover pro-tilted supporter 4 of maxillary 7, and the clip 17 through being with spring cooperates running fix with dentation draw-in groove 16.One occipitalia belt loop 12 is arranged at the bottom of vertical support frame 3, is used for fixing with patient's head.But on maxillary 7, also have move left and right also can regulate the pallet fixation clamp 8 at the upper jaw pallet elevation angle, have adjusting knob 10,11 to be respectively applied for fixedly upper jaw pallet and location on it.The elastic traction band 15 that also has upper jaw pallet 9, auxiliary belt loop and traction jawbone to use in addition, auxiliary belt loop includes and can form by patient's occipitalia belt loop 12, front belt loop 13, the back belt loop 14 on one's body that be fixed on that the maxillofacial fracture reduction fixture device is firm, the connecting hole of one end of front belt loop 13, back belt loop 14 and mandibular arch 6 rear ends is connected and fixed, the other end is wrapped in the patient and is used to assist fixedly maxillofacial fracture reduction fixture device on one's body, makes it can displacement.Elastic traction band 15 is made up of steel hook and elasticity rope band.Upper jaw pallet 9 is used for upwards resetting upper jaw bone, and elastic traction band 15 is used for the jawbone of outside tractive distortion.Through checking on probation, better between preceding tilted supporter 4 and the vertical support frame 3 to form 22～40 ℃ angle effect.

During use, with this utility model product tape on patient's head, regulate auxiliary belt loops such as velcro and occipitalia belt loop and front belt loop, back belt loop and fix head cap, upper jaw pallet one end is inserted in patient's mouth, the other end is clamped through the pallet fixation clamp, by move up and down maxillary the position, and regulate the elevation angle of upper jaw pallet by the pallet fixation clamp, its upper jaw with fracture is effectively upwards held up.Work as appearance, the cheekbone of fracture is when internal strain, the steel hook of available elastic traction band hooks upper dental bed or corresponding site, and the elastic traction band is walked around maxillary upwards or be fixed on cheekbone traction frame or the mandibular arch downwards, can be with the outside reduction by traction of cheekbone.
