Abstract
A fracture resetting holder for clinical curing inferior wall of orbit fracture is provided. The resetting holder is mounted in maxillary antrum. In resetting holder, the supporting platform connects with movable column, the movable column connects with fixed column foundation by screw-thread and the height can be adjusted, the stop nut is located under the movable column to fix the height, the supporter of resetting holder is under fixed column foundation. The resetting holder cures inferior wall of orbit fracture through maxillary antrum, so facial cut can be avoided and perfect curative effect can be got. the invention is suit for various inferior wall of orbit fracture resetting, the height can be adjusted, the material is firm and innocuous, the invested cost is low, it's easy to use, flexible to operate, the effect of treat is reliable.
Description
(1) technical field:
The present invention proposes a kind of orbital floor fracture that is used for and resets fixed medical apparatus and instruments specifically, is a kind of facia incision of avoiding, and carries out the reduction fixture device (abbreviation: reduction fixture device) that orbital floor fracture resets through maxillary sinus.
(2) background technology:
The patient of orbital floor fracture deprimens oculi usually occurs and embeds phenomenon in the maxillary sinus, patient's diplopia, limited, the atrophy of eyeball of ocular movement.The treatment of orbital floor fracture at present adopts facial palpebra inferior otch to carry out the reduction of the fracture, with titanium plate or other synthetic material repair of bone fractures, this treatment aspect is because facia incision causes damage for patient's face, thereby the application of next artificial material easily causes the asymmetric diplopia that causes in position of double eyeball.Facia incision has been avoided in the invention of this reduction fixture device, adopts oral cavity epipharynx gum intersection otch, chisels the maxillary sinus antetheca positor is inserted in the maxillary sinus, carries out orbital floor fracture in the maxillary sinus to reset.The positor lower end is fixed in the taper nest of maxillary sinus bottom, fixing special the lower end is designed to lower end with three pillars for avoiding injuring the root of the tooth tissue in the hole and being convenient to.Parallel slightly concavity plane, upper end is with the paries inferior orbitae jack-up of fracture, and big spy is designed to height adjustable structure with positor because of hole internal volume individual variation, with spanner positor is transferred to the osteocomma that suitable height can be fixed fracture.Postoperative took out holder from former otch after one month.By clinical principium use to find with this reduction fixture device treat orbital floor fracture to patient bring painful little, damage is light, patient's diplopia after operation disappears, ocular movement freely, in addition, this diplopia, holder are solid, durable, nontoxic, cost is low, flexible operation is as then having tangible economic and social benefit in clinical popularization and application.
(3) summary of the invention:
The present invention proposes a kind of reduction fixture device that satisfies the treatment of clinical orbital floor fracture,, the misery brought light to patient trauma and side effect is little, therapeutic effect is reliable.The characteristics of this reduction fixture device are that its portable stanchion outward appearance is a hexagon, adjustable height.Its material can be rustless steel or various alloy and or organic synthetic material in a kind of.
The present invention mainly by on have a concave surface spheroidal support platform 1, portable stanchion 2, lock nut 3, anchor post base 4, holder leg 5 form.Wherein upper support platform 1 be the upper end parallel slightly concavity the plane, with portable stanchion 2 by being welded to connect, be used to support the paries inferior orbitae of fracture.Portable stanchion 2 and anchor post base 4 are by being threaded, to satisfy the instructions for use of reduction fixture device.What lock nut 3 was used for fixing portable stanchion 2 and anchor post base 4 is connected fixed reset holder height.Reach on anchor post base 4 screw rods is greater than the length overall of portable stanchion 2 with lock nut 3 female threads, and portable stanchion 2 and lock nut 3 outward appearances are hexagon, are suitable for regulating with spanner.Reduction fixture device leg 5 is connected with anchor post base 4 by welding, becomes 120-150 degree angle of cut (see figure 10), is used for positor is fixed in the alveolar taper nest of maxillary sinus.Reduction fixture device leg 5 has three, and its summit becomes equilateral triangle to arrange, and the top is circular, prevents that reduction fixture device from damaging maxillary sinus alveolar process crypts.
Be described in detail operation principle of the present invention below: at first reduction fixture device is adjusted to minimum altitude, and transfer the tight nut 3 that uncages by adjusting portable stanchion 2.At patient oral cavity epipharynx gum intersection otch, chisel the maxillary sinus antetheca, positor is inserted in the maxillary sinus, be fixed in positor in the taper nest of maxillary sinus bottom by leg 5, using support platform 1 plays the paries inferior orbitae of fracturing surely, regulate portable stanchion 2 with spanner positor is transferred to suitable height,, fix the osteocomma of fracture with lock nut 3 lockings.Perform the operation back one month from former otch taking-up reduction fixture device.
Major advantage of the present invention is an adjustable height, can adapt to not co-content of human body maxillary sinus chamber.In addition, avoid facia incision,, the misery brought light and side effect is little, therapeutic effect is reliable to patient trauma.

(5) specific embodiment:
According to volumetrical the varying in size in patient's maxillary sinus chamber, the orbital floor fracture reduction fixture device of orbital floor fracture area size and shape different designs different shape size and various materials.
Embodiment 1:
In patient's 1 operation, the reduction fixture device support platform is the spheroidal concave surface of radius R ' 5mm, and the hexagonal circumscribed circle diameter of outward appearance is 5mm, reduction fixture device total height 2.5cm, and 150 ° of leg and base lower plane angles, the material of reduction fixture device is a rustless steel.Perform the operation back one month from former otch taking-up reduction fixture device, the patient is all right.
Embodiment 2:
In patient's 2 operations, the reduction fixture device support platform is the spheroidal concave surface of radius R ' 5mm, the hexagonal circumscribed circle diameter of outward appearance is 5mm, reduction fixture device total height 2.2cm, and the material of leg and 120 ° of reduction fixture devices of base lower plane angle is the organic synthesis material.Perform the operation back one month from former otch taking-up reduction fixture device, patient 2 recovers fine.
