Description
Technical field
This utility model relates to the plintlet band that is used for external fixation of fracture, mainly is meant a kind ofly to have that the band pulling force is constant, the external fixation of fracture plintlet constant force band of automatic warning function.
Background technology
Tradition fracture fixation method roughly comprises following several kinds:
1. the method for the fixing fracture of common gypsum, this method exist volume big, heavy, airtight, be prone to get loose, difficultly regulate, defectives such as easy formation pressure ulcer.
2. the method for resin Gypsum Fibrosum bone fixation folding, there are defectives such as high, the difficult adjusting of expense in this method.
3. plintlet external fixation: manual reduction and plintlet external fixation are the characteristic and the advantages of Chinese traditional treatment fracture, obtain the approval in the world already.Plintlet have letter, just, test, honest and clean advantage, be maximum external fixation of fracture method and the equipment of the present clinical use of China.Wherein volume of production maximum, the use with the willow clamping plate is the most extensive.
Small splints fixation is from the physiological function of limbs, through band to the restraining forces of clamping plate, pressure pad to fracture site being prevented or corrects the efficacy of displacement, and make full use of limb muscle and shrink the internal motivation that produces, impel fracture stabilization, healing.The plintlet external fixation has embodied traditional Chinese medical science organic conception " being association of activity and inertia " principle with fixing fracture.
" AO " theory and the technology of strong internal fixation praised highly by western countries over nearly 30 years, more because of clinical drawback, and then turns to and pays attention to fixing biology that protection blood supplies (B0 is theoretical).Advocate flexible fastening (fine motion is fixed) according to China's tradition synthetism theory and day by day sophisticated traditional Chinese medical science synthetism (CO), through experiment and a large amount of clinical research confirmation, curative effect can meet or exceed the open reduction internal fixation treatment fully.Plintlet best embodies the fixed principle of fine motion, and therefore, the plintlet external fixation bone-fracture treatment is still science and advanced Therapeutic Method so far, will continue as human health and make contributions.
The defective that plintlet exists:
The subject matter of tradition clamping plate is that the imbalance because of the defective of material and band elasticity causes fixedly that dynamics is out of control, clamping plate and pressure pad displacement, pressure ulcer and infection, nerve injury, limb ischemia necrosis (even causing amputation) etc.Wherein, the loosening or tension of band is the most general problem.The judgement of the elasticity of band and adjustment need doctor's rich experience, are that the patient is difficult to grasp, and this is to affect the treatment and cause the main cause of severe complication.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further specified:
As shown in the figure, this plintlet constant force band mainly is made up of constant force wind spring 1, band 60, plintlet 50 and sound light alarming circuit, and constant force wind spring (being similar to the clockwork spring of clock and watch) 1, band 60, plintlet 50 and sound light alarming circuit all are contained in 10 li of control boxes.
Sound light alarming circuit is provided with the circuit contact 2,3 that is connected with the band contact, realizes the sound and light alarm that the band pulling force transfinites.
Operation principle
Use constant force wind spring, band, plintlet, band one end and constant force wind spring are connected to form the constant force band, around fracture site, attach 4-5 piece plintlet (see figure 8); Be fixed with 3-4 control box 10 on a plintlet therein, control box 10 internal fixation have constant force band and circuit board, and band is pulled out from control box 10 1 ends; Walk around all the other 3 plintlets, hang over band and draw and buckle on 11,4-5 piece plintlet and fracture site are pricked tied up together; At this moment the constant force wind spring is in the state of drawing back, and when fracture site was progressively subsided a swelling, the constant force wind spring can progressively tighten up; At this moment band is also along with tightening up, and pricks simultaneously that to tie up power constant; In like manner, when fracture site progressively during swelling, the constant force wind spring can progressively elongate, and at this moment band is also along with elongation, pricks simultaneously that to tie up power constant.
Be provided with the markings (showing in the window at control box) that show band pulling force size on the band, on band, also having alarm actuating contact.The buzzer and the display lamp that receive circuit control are arranged on control box, also have 2 alarm actuating contacts.When the band correct tension, display lamp does not work, buzzer does not ring, the markings point is central at window; When the band pulling force is too small, the contact circuits for triggering on the band, display lamp glassy yellow, buzzer ring, markings are near the yellow end of window; When the band pulling force was excessive, the contact on the band is circuits for triggering also, and display lamp shiny red, buzzer ring, markings point is near the red end of window; When pulling force was excessive or too small, patient can oneself adjust the band pulling force.
When Fig. 4 was the band correct tension, display lamp did not work, buzzer does not ring, markings are emerging in green area.
Fig. 5 is band pulling force when too small, and display lamp glassy yellow, buzzer ring, markings are emerging in yellow area.
Fig. 6 is band pulling force when excessive, and display lamp shiny red, buzzer ring, markings are emerging in red area.Explain:
Band: be wide about 1 centimetre chemical fibre ribbon, require more smoothly, can bear the above pulling force of 50 newton.
" move with the hand ": the meaning of " moving with the hand " is to lift earlier the afterbody of clasp gently, can loosen traction force, and is the same with the operation that begins subsequently, the afterbody of tractive band.Two actions are summarized with " moving with the hand ".
Clasp on the band: the effect of clasp is just as the cingulum on the sandals, and band is through the clasp opisthotonos, oppositely tractive band and strain band; The 2nd, play the effect of unidirectional pulley, promptly can not form the band retraction during tractive band and loosen (reducing pulling force); The 3rd, hook is arranged on the cingulum, can accomplish the annular bundle of band and tie up.
The spring assembly of every employing and this constant force wind spring same application all belongs to the protection domain of this utility model.
