Description
Technical field
The utility model relates to medical instrument more particularly to a kind of elastic support arms for treating bone hammer finger.
Background technique
Hammer finger is damage more typical in a kind of people's daily life, if early stage deal with improperly can lead to it is chronic concurrent
Disease causes pain, dysfunction, and influences beauty.Bone hammer finger is common in work or injury gained in sports, shows as extensor flesh
Tendon is from distal phalanx base avulsion and has sclerite.If distal phalanx may be finally fixed in the wrong without treatment
Qu Wei, proximal phalanx is then in hyperextension position.
At present about the optimal treatment mode of bone hammer finger there is also dispute, scholars describe different conservative therapys
Scheme, but be more than 1/4 patient for those distal phalanx base avulsions, prognosis is unsatisfactory.Operative treatment mode
It is fixed after having open reduction with Kirschner wire, tension band etc., but postoperative be likely to occur of patient resets loss, steel needle displacement even
The complication such as sclerite ischemic osteonecrosis.
Summary of the invention
In order to solve the above technical problems, it is outer to be to provide a kind of elasticity for treating bone hammer finger for the utility model aim
Bracket, the support arm is convenient with surgical procedure, no rejection, eutherapeutic feature.
In order to achieve the above purpose, the utility model uses technical solution below:
A kind of elastic support arm for treating bone hammer finger, the elasticity support arm include the first Kirschner wire, the second Kirschner wire
And elastic component；First Kirschner wire can be close to sclerite back side and be inserted into middle phalanx through middle phalanx facies articularis capituli edge,
With middle phalanx axis for 0 °, needle angle is 25 °~45° angle, and the backshank of the first Kirschner wire is rolled over downwards above phalangette
Form the first hook part；Second Kirschner wire can laterally thread a needle in phalangette side middle line and perpendicular to the phalanges longitudinal axis, the second kirschner
Needle forms the second hook part in the difference bending of finger two sides；The elastic component connects the first hook part and two the second crotches
Portion.
As a further improvement, the elastic component is elastic tape.
As a further improvement, second Kirschner wire at the 3mm of finger two sides respectively acute angle bending formed it is described
Second hook part.
As a further improvement, the diameter of first Kirschner wire is 1.2mm, the diameter of the second Kirschner wire is 0.8mm.
The utility model due to the adoption of the above technical solution, compare by the prior art, the utility model has the advantages that: 1.
It is not in surgery cut infection and the dermonecrotic risk of notch using closed needle threading；2. outer without plaster slab or brace etc.
It is fixed；3. not damaging epiphyseal plate, not the thin-skinned bone of injured joint, the cartilage degeneration caused because joint runs through fixed can be prevented, closed
The secondary lesions such as condyle contracture；4. stretching and beading phalangette balance of power is made by lever principle antagonism flexor digitorum muscle of hand tendon muscular strength,
Early stage is conducive to the healing of sclerite；5. without inner matter and knot rejection；6. surgical procedure is easy, secondary open surgery is not had to
It is fixed in taking out；7. cheap；8. allowing to go remote interphalangeal joint functional training as early as possible in the case where elastic external fixation bracket is protected, keep away
Exempt from anchylosis.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the first Kirschner wire.
Fig. 3 is the structural schematic diagram of the second Kirschner wire.
Specific embodiment
Specific embodiment of the present utility model is made a detailed explanation with reference to the accompanying drawing.
A kind of elastic support arm for treating bone hammer finger as shown in Figure 1, the elasticity support arm include the first Kirschner wire
1, the second Kirschner wire 2 and elastic component 3；The diameter of first Kirschner wire 1 is 1.2mm, and the first Kirschner wire 1 can be close to sclerite
6 back sides through middle phalanx facies articularis capituli edge be inserted into middle phalanx 7, with 7 axis of middle phalanx be 0 °, needle angle be 25 °~
45° angle, the backshank of the first Kirschner wire 1 first hook part 4(of folding formation downwards above phalangette 8 are as shown in Figure 2)；Second gram
The diameter of family name's needle 2 is 0.8mm, and the second Kirschner wire 2 can laterally thread a needle in 8 side middle line of phalangette and perpendicular to the phalanges longitudinal axis, the
The second hook part 5(of acute angle bending formation is as shown in Figure 3 respectively at the 3mm of finger two sides for two Kirschner wires 2)；The elastic component 3
For elastic tape, elastic component 3 connects the first hook part 4 and two the second hook parts 5.According to fracture fixation needs, pass through rubber band
The first hook part 4 and the second hook part 5 are connected, adjustment rubber band maintains the first Kirschner wire 1 to have certain elastic resistance, and makes
Remote interphalangeal joint is fixed on slight dorsiflexion position.
