Abstract
A draught outer fixer for mandible fracture comprises an arch arm, a stretching belt with one end connected with the suspended end of the arch arm. The utility model is characterized in that a neck ring 1 and a bone nipper 2 are also arranged, wherein the arch arm consists of two main L-style arms 6 and a stretching arm 4, one end of the two main arms is fixed on the left and right sides of the neck ring symmetrically, the other suspended ends of the two main arms are connected with each other and connected with the stretching arm 4, the mouth of the bone nipper 2 is a needle-like mouth with two opposite needle tips, the handle of the bone nipper is connected with a stretching belt 15, a head positioning belt 7 is arranged between the vertical ends of the two main arms. The utility model aims to provide an outer fixer without the need of inserting Kirschner wire, which has simple operation, limitation on the freedom of head movement, and decreased risk of redislocation of the mandible.
Description
Technical field
This utility model relates to a kind of jaw fracture holder, refers to a kind of fracture of mandible traction external fixator especially.
Background technology
At present, the method for clinical treatment fracture of mandible is divided modus operandi and non-modus operandi two big classes substantially.Modus operandi is meant at the affected part open reduction internal fixation that undergos surgery.This method patient is relatively more painful, and postoperative tissue reaction is heavier, retains fixture in the tissue, and scar after the operation is obvious.For the mandibular bone that makes fracture obtains rectification and recovery fast, some healthcare givers tend to adopt the simple relatively non-modus operandi of operation.Non-modus operandi adopts Arch bar splint ligation reset fixing means and the arc elastic plate fixing means of mandibular bone more.
The Arch bar splint ligation fixing means that resets is a kind of traditional Therapeutic Method, and often because of the ligation silk causes oral ulcer, the nursing difficulty is bigger.
The arc elastic plate fixing means of mandibular bone be by be worn over head hoop and the Bamboo strip plate of fixedlying connected on patient's head from the beginning the back be arc with head hoop extend to head before, end with rope connects the Bamboo strip plate end, the other end connects the Kirschner wire that is through mandibular bone, and traction resets.Though make in this way simplyr than the Arch bar splint ligation fixing means that resets, its weak point is also arranged: 1, must hole on mandibular bone, in order to intert Kirschner wire, trouble operates also; 2, head hoop is worn on the head, and the degree of freedom of neck is uncontrollable, and in active procedure, the probability that mandibular bone is misplaced by external force once again is higher easily.
The utility model content
The purpose of this utility model is to provide a kind of Kirschner wire that need not intert, and is simple to operate, and can limit the degree of freedom of head, reduces misplace the once again fracture of mandible traction external fixator of probability of mandibular bone.
For realizing described purpose, the technical solution of the utility model is as follows: fracture of mandible traction external fixator, comprise bow arm, tractive band, and an end of tractive band is connected with the free end of bow arm.Also be provided with a neck ring and a card bone forceps.The bow arm is made of two L-shaped principal arms and a draft arm, one end symmetry of two principal arms is fixed on the left and right sides of neck ring, the other end cantilever of two principal arms intersects and is connected with draft arm, the jaw of card bone forceps is the relative pin mouths of two needle points, the handle of card bone forceps is connected with the tractive band, is connected with the head positioning belt between the vertical end of two principal arms.Described tractive band, head positioning belt are the elastic force elastic cord.
The rounded goods ellipse of described neck ring.Described neck ring is punished into left and right sides two halves and overlap joint at the plane of symmetry, and connects by butterfly bolt.The skin of neck ring is tied up and is wrapped with soft layer.
Another kind of scheme is: the maximum gauge two ends of described neck ring respectively are provided with a hinge, and the centre is taken a mouthful place and connected by butterfly bolt.
This utility model is in use earlier opened neck ring, is buckled on patient's neck, is with the head positioning belt behind the head, and connects by butterfly bolt, and the vertical end of two principal arms is positioned at the both sides of head; Mandibular bone manual reset with the patient; Be stuck in the position that needs traction and fixation by the card bone forceps again; To be connected the tractive band with the card bone forceps and be enclosed within on the draft arm, regulate the position of draft arm, and make the traction dynamics of card bone forceps moderate, by butterfly bolt draft arm will be fastened on the end of L-shaped principal arm again.

The specific embodiment
As shown in Figure 1 and Figure 2, this utility model comprises bow arm, tractive band, and an end of tractive band is connected with the free end of bow arm.Be provided with a neck ring 1 and a card bone forceps 2.The neck ring skeleton is made by steel plate or engineering plastics, and skin is tied up and is wrapped with soft layer, as rubber, foam rubber, plastic foam etc.The rounded goods ellipse of described neck ring.The bow arm by two L-shaped principal arms 6,6 ' and a draft arm 4 constitute.Draft arm is provided with the rope position mouth 3 that prevents the dislocation of tractive band.A principal arm and a draft arm are made by steel plate or engineering plastics.One end symmetry of two principal arms is fixed on the left and right sides of neck ring.The other end cantilever of two principal arms intersects and is connected by butterfly bolt 10 with draft arm 4, is provided with spring pad 5 in the junction of draft arm and principal arm.Between the vertical end of two principal arms, be connected with head positioning belt 7.Described tractive band, head positioning belt are the elastic force elastic cord.
As shown in Figure 3.Described neck ring 1 is punished into left and right sides two halves and straight mouthful of overlap joint at the plane of symmetry, and connects by butterfly bolt 8,9.
As shown in Figure 4.The maximum gauge two ends of described neck ring respectively are provided with a hinge 11,12, and at the rear portion of neck ring middle straight mouth overlap joint, and by butterfly bolt 8 connections.
As shown in Figure 5.The jaw of card bone forceps 2 is that the handle 13,14 of the relative needle-like jaw of two needle points 16,17 card bone forceps is connected with tractive band 15.
