Abstract
The utility model relates to a fixing traction frame for medical treatment, in particular to a single-finger reverse traction external fixing frame, which comprises long and short 'U'-shaped main bodies, opening ends of the two U-shaped main bodies extend towards the same direction and are both provided with fixing fasteners, the fixing fasteners are provided with Kirschner wires, the width of the short U-shaped main body is smaller than that of the long U-shaped main body, the short U-shaped main body is arranged inside the long U-shaped main body, lateral edges of the main bodies are sleeved via sleeves, a closed end of the long U-shaped main body is provided with a groove while the closed end of the short U-shaped main body is provided with a hook-shaped projection, and the hook-shaped projection is connected with the groove through an elastic component. Compared with the prior art, the single-finger reverse traction external fixing frame is simple in structure and convenient in operation, only needs a common hand drill or electric drill rather than special tools, is short in time without bleeding during operation, and is low in hurt of partial tissue and favorable for fracture healing during early stage. In addition, patients can exercise functions of metacarpophalangeal joints and interphalangeal joints during fixing period, thereby reducing anchylosis incidence rate.
Description
Technical field:
This utility model relates to a kind of medical fixed traction frame, a kind ofly specifically singly refers to oppositely draw external fixer.
Background technology:
Owing to the traction action of tendon, make the fracture end cripetura overlapping after hand 2～5 finger middle phalanx syntripsises, or intercalation; Traditional Gypsum Fibrosum or plintlet external fixation difficulty reach ideal reset effect, open reduction and internal fixation difficulty, and periosteum is extensively peeled off the back influences the interior fracture of union of fracture, particularly finger joint style, more difficult anatomical reduction or the functional reduction of reaching of traditional internal fixation.
Summary of the invention:
Goal of the invention of the present utility model is to overcome the deficiency of background technology and provides a kind of simple to operate, and can make fracture obtain reduction with good and fixed external fixation traction frame.
This utility model adopts following technical scheme:
A kind ofly singly refer to oppositely draw external fixer, comprise length, short two main bodys that are " U " shape structure, and the opening of two U-shaped main bodys extends to same direction, the opening of described two U-shaped main bodys is equipped with fixing card, should on the fixing card Kirschner wire be housed, the width of described short U-shaped main body is less than long U-shaped main body, described short U-shaped main body places long U-shaped body interior, the side of this two main body is by the sleeve pipe socket, the blind end of described long U-shaped main body is provided with groove, the blind end of described short U-shaped main body is provided with hamulus, and this hamulus is connected by elastomeric element with groove.
This utility model that adopts technique scheme compared with prior art has simple in structurely, easy to operate, does not need special tool(s), only gets final product with common bitbrace or electric drill; Time is short, and it is no hemorrhage to perform the operation; Local tissue damage is little, is beneficial to fracture heals in early days; Can carry out the function exercise of metacarpophalangeal joints and interphalangeal joint during fixing, reduce the incidence rate of ankylosis.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a user mode reference diagram of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing in detail this utility model is described in detail:
A kind ofly singly refer to oppositely draw external fixer, referring to accompanying drawing 1,2; Among the figure: long U-shaped main body 1, sleeve pipe 2, first passage 3, second channel 4, groove 5, rubber band 6, hamulus 7, short U-shaped main body 8, first fixing card 9, first Kirschner wire 10, second fixing card 11, second Kirschner wire 12; Minor details 13, closely save 14.
The opening of long U-shaped main body 1 and short U-shaped main body 8 extends to same direction, and the opening of long U-shaped main body 1 is provided with the second fixing card 11, and the opening of short U-shaped main body 8 is provided with the first fixing card 9.
On the first fixing card 9 first Kirschner wire 10 is housed, on the second fixing card 11 second Kirschner wire 12 is housed, the width of short U-shaped main body 8 is less than long U-shaped main body 1, the side of long U-shaped main body 1 and short U-shaped main body 8 is by sleeve pipe 2 sockets, the blind end of long U-shaped main body 1 is provided with groove 5, the blind end of short U-shaped main body 8 is provided with hamulus 7, and hamulus 7 and groove 5 are connected by elastomeric element.
As a kind of structure of preferably selecting of present embodiment, sleeve pipe 2 is provided with two passages, is first passage 3 and second channel 4, and the side of long U-shaped main body 1 places in the first passage 3, and the side of short U-shaped main body 8 places in the second channel 4.
Further preferred structure as present embodiment, the quantity of sleeve pipe 2 is set to two, one of them is sleeved on the limit, left side of long U-shaped main body 1 and the limit, left side of short U-shaped main body 8 by first passage 3 and second channel 4 respectively, and another is sleeved on the right edge of long U-shaped main body 1 and the right edge of short U-shaped main body 8.
As the further preferred structure of present embodiment, elastomeric element is an elastic rubber band 6.
The using method of present embodiment is:
Nearly joint 14 phalanges far-ends that refer to respectively at wound and minor details 13 phalanges substrates, side center line respectively pierce the Kirschner wire of one piece of diameter 1.0mm perpendicular to phalanges, be respectively second Kirschner wire 12 and first Kirschner wire, 10, the first Kirschner wires 10 and second Kirschner wire 12 and be parastate.Finger is placed in the space between the dual-side of two U-shaped main bodys, adjust the position of short U-shaped main body 8 on long U-shaped main body 1, fixedly pass second Kirschner wire 12 of proximal phalanx with the fixing card 11 of second on the long U-shaped main body 1, fixedly pass first Kirschner wire 10 of phalangette with the first fixing card 9 on the short U-shaped main body 8, be connected by elastic rubber band 6 between the hamulus 7 of the groove 5 of long U-shaped main body 1 and short U-shaped main body 8, and adjustment rubber band 6 elastic force bend and stretch the pulling force of tendon with antagonism.The blind end that to lack U-shaped main body 8 by the pulling force of elastic rubber band 6 pulls to the blind end of long U-shaped main body 1, as shown in Figure 2, causes two pieces of reverse shift separations of Kirschner wire, and fracture end is retracted, and reaches reset effect.
Present embodiment has simple in structure, and is easy to operate, do not need special tool(s), only gets final product with common bitbrace or electric drill; Time is short, and it is no hemorrhage to perform the operation; Local tissue damage is little, is beneficial to fracture heals in early days; Can carry out the function exercise of metacarpophalangeal joints and interphalangeal joint during fixing, reduce the incidence rate of ankylosis.
