Abstract

Device for therapeutic immobilization and the setting of the limbs under angle is two- functional, adjustable, reusable instrument for optimal healing (and without surgery) of complex fractures and other traumas of the limbs - because it enables right bone reposition, fixing and coalescing - and for extension strong contracted joints, too. It consists assemblage of joint shaft which is installed at the treated joint under the therapeutic needed angle and connected with sticks and spirals along the whole treated limb. This adaptable device is a more efficient therapeutic instrument than plaster casts - this device can be used on modern orthopedic and traumatological therapy of limbs.

Description

DEVICE FOR THE SETTING AND IMMOBILISATION OF THE LIMBS - UNDER ANGLE

Area of the invention

This invention refer to therapy of joint fractures, varied bone fractures or other hard injuries of limbs where it is need its immobilisation in bended joint position (the most often of elbow or knee-joint) under needed angle from 90° to 10°. Also, area of this invention is the setting (correction, in fact - extension) of hard contracted joints (on example 30° , 40° or more degrees).

Technical problem

Technical problem is conception and operationalisation of the instrument which will enable to optimal regeneration hard injured, especially complex fractured limbs by uninvasive, physiological more acceptable way which is more pleasant for patients and more simple to usage from now used instruments for healing same kind injuries of limbs.

For curative (extension) strong contracted joints, more than 20°, except big joints as knee or elbow it's need to make such orthose by which we can - on physiological acceptable and simple way - firmly embrace contracted limb and reduce (on slight way) angle of contracture graduatelly, giving back to function of treated limb.

This device has both uses (assignments) - angle immobilising one and intensive extensing one - it is repeated usable and simply applicatable. State of art

Thrapical immobilisation of limbs under angle is performed today by plaster cast which isn't so functional immobilisation instrument because it makes heavy, compact and inflexible plating and charges injuried limb additionally. It disturbs bloodstream and inhibits skin respiration at immobilised area. hi spite of all that, plasten cast cann't fixes bone fragment precisely and it's often need, before application of plasten cast, to surgical fix fractured bone (and it is physiological shock and risk for patient).

Not rarely, bone fragments are not fixed rightly by surgical operation, too.

Orthoses for efficient extension (setting) of strong joint contractures are not be today.

Essence of the invent

Essence of the invent is project of device which enables immobilisation of hard fractured or injured limbs on physiological acceptable, simple and quick way, under therapical needed angle and anatomical adequate reposition and fusing bone fragments without surgery. This device would be optimal instrument for healing complex fractured limbs and fractures of joints, when it's need immobilisation under angle, hi the second its function this device is efficient orthose for setting of strong contracted joints (from 20 degrees to more) which we haven't, today.

Detailed description of realization and application of the invent

The device is formed of joint shaft tied to sticks and spirals (this two last elements are specificated into pat. application : «Splint for the setting and immobilisation of the limbs», by Smilja Tadic (WO/2007/003973). The joint shaft is consist from two pairs of firm, unbreakable, squared tiles (1). The tiles in each pair are connected mutually, along one its side, by hollow roller clamp (like hinge). Each pair of this tiles (1) is connected - in both its opposite corners on both its sides - by one two-part angle regulating lever (2) which lenght is regulated by pulling its half part of full cross-section in or out (according to needed angle) adequate dimensioned hollow, tube half part Needed length of this angle regulating levers (2) is fixed by bolts with nuts or telescopely. It's important that indicated angle of immobilisation or extension would be fixed firmly and stably. Angle at angle regulation levers (2) has to be adjustable at each 5° of inerspace in span from 90° to 0° .

The pair of tiles (1) on internal side of the joint immobilised under angle can to have tree angle regulating levers (2) - third in the middle - because of making fast of immobilisation, when it is needed.

The angle regulating levers (2) are attached flexibly at tiles (1) by adequate rivets that would can change angle of connection to tiles (1).

Both pair of tiles (1) on upper and lower its corner on both sides connected by 4 joint embracing levers (3) which are of same kind like angle regulating levers but on this position they have function of joint embracing. Joint embracing levers (3) are firmed at tiles (1) by bolts with nuts, their length is adjustable and function of this levers (3) is adapting of joint shaft to volume of treated joint.

Lenght and width of tiles (1) have to be from 2- 20 cm, depended on dimensions of the limb. One pair of tiles (1), of adequately dimensions, is placed at external side of the banded joint and another pair of ones (1), of proportionally less lenght, at its internal side and adjust joint embracing levers (3) and angle regulating levers(2). hi the middle of each tile (1) there is niche dimensioned toward stick which ending part stably rests into it.

Sticks, from ends of joint shaft to both ends of treated limb are embraced by two spirals (the second one over the first one) along each half part of the limb. Except sticks which we install into niches of tiles (1), we have to firm of immobilisation by several else sticks (according to need) under of spirals, along both half part of treated limb. For example A- Immobilisation under angle varied fractured hand

After reposition osteofragments and bandaging surface wounds (if it's such case), we have to band treated hand at elbow under angle of 90° , dress it by layer (width 2-3 cm) of cotton in gauze and than at elbow firm joint shaft in adequate dimensions, adjust lenght of 4 joint embracing levers (3) and fix lenght of angle regulating levers (2) so that two pairs of tiles (1) would form therapical needed angle of immobilisation (at this case in the first phase of curative it is angle of 90° ). - Than we have to install ending parts of adequating sticks into niches in the middle of tiles (1) in front side and back one of upperarm and forearm. Two spirals (the second one over the first one) embrace and fix sticks along upper arm and forearm. Along left and arm sides of upperarm and forearm, under spirals , we have to firm a few else sticks of adequate dimensions that the immobilisation would be equipoise, solid and steady.

During healing of such injuries, it will probably need to diminish angle of immobilisation and it's simply to perform by this device.

For example B — Setting (extension) of 40° knee joint contracture

It has to protect treated food by 2- 3 cm thick layer of cotton in gauze and place adequate dimensioned joint shaft which is here in function of orthose. We have to firm it at knee by joint embracing levers (3) and adjust joint shaft, by angle regulation levers

(2) at angle of 5° less than angle of contracture, so at 35° .

At contracted joint we have to firm sticks and spirals (in same way like at described immobilisation) along thigh and shin. Depended of tempo of knee extension as effect of this orthose (this tempo is individual) we have to diminish angle of orthose, graduatelly, for each 5° of joint extension.

This orthose is applicable as instrument for self-help. Way of application

The device is applicable on orthopedic, traumatological and veteriny practice as optimal therapical instrument at strong traumas and deformities of limbs. It's substitute for curative problematical and unpractical plasten cast and for many surgical operations of this kind of injuries because we can by it to anatomical precisely and stably fix bone fragments of treated limb.

It is applicable also as orthose for extension of strong limb contractures which can't be contenting resolved till today.

The device is applicable durably, with sterilization.

Joint shaft, its central element, is simply to construct and it can be made (in more dimensions) of unrusting metal, for example, steel.

So, production of this device is technological simple, inexpensive and profitable.
