Description
Technical field
The utility model relates to medical instruments field, specifically a kind of boxer fracture reduction fixture device.
Background technique
The fifth metacarpal bone fracture of cervical vertebra of hand is also known as " boxer fracture ", is more common in teenager, whens hitting object suddenly with fist, beat wall etc.
It is easiest to cause such damage, Injury mechanism is that metacarpal head directly hits hard object and causes metacarpal bone neck weak by conducting violence
Place fracture.Fracture is mostly cross-section or comminuted, and due to the drawing of interosseous muscles of hand after fracture, metacarpal head thenad is rolled tiltedly, fracture
To back side angulation.
Treatment method has operation and conservative therapy, and operative treatment needs invasive open reduction, medical expense height, patient's pain
Hardship has infection risk, largely needs second operation to take out interior fixed, and partial surgical needs to assist to fix outside plaster slab, together
When had both the disadvantage of interior fixation and outer fixation.
Non-operative treatment, can be fixed outside using fixed or palmar plaster slab outside U-clamp plate.Using fixed outside U-clamp plate
Method, since Scaphoid bone tubercle is directed toward in little finger of toe end, little finger of toe is not two parallel planes with facies palmaris.And U-clamp plate upper and lower two is flat
Face is parallel, the unjust shape of ruler before easily little finger of toe being caused to revolve.U-clamp plate is in metacarpophalangeal joint without support metacarpal head fulcrum, the easy angulation again of fracture
Displacement.For fixed super wrist joint to finger tip, MCP collateral ligaments is in tension outside palmar plaster slab, acts on fracture stabilization.It lacks
Point is that metacarpal head local stress is weak, and reset effect remains not good enough.2~4 refer to that the set time is long, influence daily life and are unfavorable for early stage
Functional training.After fracture detumescence, plaster slab is loose, and local stress disappears, the easy angulation displacement again of fracture.
Utility model content
The utility model is exactly to solve the above-mentioned problems, to provide a kind of boxer fracture reduction fixture device.
The utility model is implemented according to following technical scheme.
A kind of boxer fracture reduction fixture device, including steel bar and spring leaf, steel bar and spring leaf pass through rivet interlacement, steel bar
Upper one end close to rivet is equipped with regulating mechanism；The regulating mechanism includes elastic overcoat and adjusting component；The elastic overcoat
It is fixed on steel bar, forms through-hole on the contact surface of elastic overcoat and steel bar, be equipped with air bag in through-hole；It is wrapped in the adjusting component
Include the rotary shaft for running through and being flexibly connected with elastic overcoat, nested cam in rotary shaft；The profile of the cam and T-shaped boss
Deck contact, the lug boss nested springs of T-type boss, the insertion of lug boss end are located at logical on elastic overcoat and steel bar contact surface
In hole and and balloon contacts.
Further, the cam two sides are equipped with for being locked removable pin on the rotary shaft.
Further, the elastic overcoat is fixed on steel bar by the first screw.
Further, described rotary shaft one end forms interior hexagon shrinkage pool；Perpendicular second is fixed in rotary shaft
Screw.
Further, the spring one end is fixed on the table top of T-shaped boss, and the other end is fixed on elastic overcoat inner wall
On.
The utility model obtains following beneficial effect.
The utility model provides a kind of boxer fracture reduction fixture device.In conjunction with the advantage for appealing outer fixed form, evade
Its disadvantage, develops completely new product, between the body surface fixed point-palm band and metacarpophalangeal line created by bladder support safely and effectively
Region reaches active homing and fixation.

Specific embodiment
The utility model is described in detail with embodiment with reference to the accompanying drawings.
As shown in Fig. 1~5, a kind of boxer fracture reduction fixture device, including steel bar 1 and spring leaf 3, steel bar 1 and spring leaf 3
It is connected by rivet 4, is equipped with regulating mechanism 2 close to one end of rivet 4 on steel bar 1；The regulating mechanism 2 includes elastic overcoat 14
With adjusting component；The elastic overcoat 14 is fixed on steel bar 1, forms through-hole on the contact surface of elastic overcoat 14 and steel bar 1, is led to
Air bag 7 is equipped in hole；It include the rotary shaft 8 for running through and being flexibly connected with elastic overcoat 14 in the adjusting component, in rotary shaft 8
Nested cam 10；The profile of the cam 10 and the deck contact of T-shaped boss 13, the lug boss nested springs 11 of T-type boss 13,
The insertion of lug boss end is located at elastic overcoat 14 and contacts in the through-hole on 1 contact surface of steel bar and with air bag 7.
10 two sides of cam are equipped with for being locked removable pin on rotating shaft 8.
The elastic overcoat 14 is fixed on steel bar 1 by the first screw 5.
Described 8 one end of rotary shaft forms interior hexagon shrinkage pool；The second perpendicular screw 12 is fixed in rotary shaft 8.
Described 11 one end of spring is fixed on the table top of T-shaped boss 13, and the other end is fixed on 14 inner wall of elastic overcoat.
The application method of the utility model are as follows:
This structure is fixed by outer, the 5th metacarpophalangeal joints and nearly interphalangeal joint is made to maintain 90 °.Outer hexagonal spanner and rotation
The cooperation of axis 8 rotates clockwise, and cam 10 rotates synchronously under the action of flat key with rotary shaft 8, and cam 10 is eccentric wheel, therefore is being pushed away
During journey, due to cam 10 center at a distance from T-type boss 13 sequential change, thus can make T-type boss 13 to
Lower movement extruding gasbag 7, to make air bag 7 be slightly distorted and move downward, spring 11 under the action of T-type boss 13 also to
Lower compression；When rotation rotary shaft 8 counterclockwise, air bag 7 moves upwards under the elastic force effect of elastic overcoat, and T-type boss 13 exists
It is moved upwards under the elastic force effect of spring 11.(the second screw is contacted in extreme position with transverse slat, can limit the rotation of rotary shaft 8
Amplitude).
The interior hexagonal shrinkage pool of 8 one end of outer hexagonal spanner and rotary shaft cooperates, and rotates clockwise, 7 micro-deformation of air bag and
Micro to move downward, when moving to extreme position, about prominent 8mm plays reset and fixation to fifth metacarpal bone fracture of distal head
Effect；When 2-3 Zhou Houyou fiber poroma of fracturing, solid support fixed function is not needed, adjusts rotary shaft 8, air bag 7 counterclockwise
Reply initial position is moved upwards, solves the problems, such as local skin compressing necrosis.
