Abstract
The utility model belongs to a medical instrument, in particular relates to an external-fixing bracket for traction reduction of a maxillofacial fracture. According to the designed proposal provided by the utility model, the bracket is composed of two parts, namely a horizontal part and a vertical part, which can be separated and disassembled. The horizontal part is fixed at the tempora parts at the two sides of the skull, and the vertical part can perform adjustment according to a fracture reduction direction and is connected with the fracture section through an elastic traction rubber band. When the reduction of the fracture is achieved, the bracket can be used for external fixation. When the instrument is used to treat the maxillofacial fracture, the operation is simple and the operation trauma is small.
Description
Technical field
This utility model belongs to medical apparatus and instruments, specifically a kind of instrument that is used for maxillofacial fracture reduction by traction external fixation.
Background technology
At present, open reduction is mainly adopted in the treatment of maxillofacial fracture, carries out firm internal fixation with the titanium plate then.In carrying out such operation process, often need the zone of fracture is peeled off more widely, thereby bring bigger wound to the patient, also may bring unnecessary pair damage simultaneously.When if the patient is associated with the damage at other positions of whole body, may be because of can not tolerating this operation, and affected the best occasion for the treatment of fracturing adversely.
Summary of the invention
The purpose of this utility model is to design a kind of outer traction and fixation support, when utilizing this device to treat maxillofacial fracture, reaches the effect of Wicresoft.
According to design provided by the utility model, support is made up of horizontal component and vertical component two parts, and both can shirk.Horizontal component is fixed in the temples of skull both sides, and vertical component can move freely along the guide rail of horizontal component according to the direction that resets of fracture, after the reduction of the fracture, can be used for fixing.
Further feature is: horizontal component by about two arched arms forms, through the hinge connection, the hinge place has holding screw, at the two ends of arched arm three locating holes is arranged respectively, the upper limb of arched arm is the groove of matrix.Vertical component is made up of " L " type bar and cylindrical rods two parts, " L " type bar upper end has bayonet socket can be placed in the groove of arched arm, and has holding screw, and the cylindrical rods of lower end can be assembled mutually with " L " type bar, and can regulate in vertical direction, have holding screw equally.Have adapter on the cylindrical rods.
The utility model has the advantages that: when utilizing this support to treat maxillofacial fracture, operation wound is little.During operation, the horizontal component of support is fixed on the temples of skull both sides, on fracture segment, place traction nail, utilize the elastic traction rubber band to be connected with the adapter of support vertical component cylindrical rods, the direction that resets according to fracture segment is regulated " L " the type bar of vertical component and the position of cylindrical rods, promptly finished operation, operation wound is little.After fracture segment resetted, changing the elastic traction rubber band was steel wire, and fracture segment is fixed, and finally impels fracture to be healed completely.
Description of drawings

The specific embodiment
As shown in the figure, two arched arms (1) are linked to each other by hinge (2), have holding screw (3) on the hinge (2), the arched arm top is matrix groove (4), can be complementary with the bayonet socket (6) of " L " type bar (5) of vertical component upper end, has holding screw (7) on the bayonet socket (6), cylindrical rods (8) is entangled in " L " type bar (5) lower end, and have holding screw (9), to guarantee the location of cylindrical rods, there is adapter (11) cylindrical rods (8) lower end.
During use, two arched arms (1) are linked to each other by hinge (2),, regulate the opening angle of arched arm according to the size of patient's head, use holding screw (3) with its locking then, with screw the horizontal component of support is fixed on the temples of head both sides through the locating hole (10) at arched arm two ends.
On the fracture segment that needs reset, place an amount of traction nail then, corresponding " L " type bar (5) of each traction nail, according to the direction that resets, the bayonet socket (6) of " L " type bar (5) is placed in the groove (4) of arched arm (1), groove along arched arm carries out left and right adjusting, back holding screw (7) locking puts in place, each traction nail links to each other with the adapter (11) of a cylindrical rods (8) by the elastic traction rubber band, regulate the upper-lower position of cylindrical rods (8), use holding screw (9) locking at last, promptly finished operation.After fracture segment recovered to put in place, changing the elastic traction rubber band was stainless steel silk, is fixed on the adapter (11).
Claims (4)
1. the outer traction and fixation support of jaw face, two arched arms (1) are connected by hinge (2), arched arm (1) upper end is matrix groove (4), matrix groove (4) connects can be along the bayonet socket (6) of its " L " type bar (5) that moves upper end, and " L " type bar (5) lower end connects cylindrical rods moving up and down (8).
2. support according to claim 1 is characterized in that: the far-end of arched arm (1) has three locating holes (10).
3. support according to claim 1 is characterized in that: hinge (2) top is provided with holding screw (3), on the bayonet socket (6) of " L " type bar (5) upper end holding screw (7) is set, and " L " type bar (5) lower end is provided with holding screw (9).
4. support according to claim 1 is characterized in that: cylindrical rods moving up and down (8) is entangled in " L " type bar (5) lower end, and the lower end of cylindrical rods (8) has adapter (11).
