Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention is even more efficient than existing fixators for the treatment of limbs wrapped around the limbs of the human or animal body to assist in the correct bone union, for example in the case of a fracture. And a shell-shaped orthopedic fixator having ease of mounting.

[0002]

[Prior Art]

 As is well known, the problem of ensuring the correct binding of fractured bones is usually the so-called plaster-cast, i.e. a bandage is wrapped around the fractured limb and then the site is covered with plaster and plaster. It involves and solves a technique that consists essentially of waiting for the to dry and cure.

For many years, cast formation has been an accepted method of treating fractures and has been practiced by many in the medical field, including orthopedic surgeons, technicians, nurses and other orthopedic personnel. It has become a technology to be. Although widely practical, casts are well known to be inconvenient and cumbersome when needed for long periods of time. Another disadvantage of such casts is that they are time consuming to prepare and must be installed by a plastic surgery specialist. Once the cast is completed, the patient must carry and support the closed, heavy cast. Moreover, other problems arise, such as physical hygiene, physical discomfort and psychological problems.

[0004] Above all, in the cast, it is difficult to care for a fracture by drug treatment or to observe the treatment process. Furthermore, it is difficult for the limbs to breathe within the cast due to the lack of air circulation. Patients with casts also have to be careful not to damp the casts, which limits the degree of personal hygiene they control. Difficulties with the psychological and physical effects of casts are often associated with cast weight, length of cast use and itching of the inflamed area.

[0005]

[Problems to be solved by the device]

 The present invention provides a shell-shaped orthopedic fixator that eliminates the above-mentioned drawbacks of the prior art.

[0006]

[Means for solving the problem]

 It has been found that all the above mentioned drawbacks can be overcome by employing the shell-shaped orthopedic fixator according to the invention, which has the further advantage that it can be more easily applied to impaired limbs. ..

Two shell halves shaped and sized to the limbs to be secured, and a flexible material support cushion and a cushion as described above, which are mounted inside each said shell half By accurately fitting the groove between them, the air hole penetrating through the main bodies of the two shell half halves, and the edge of the two shell half halves together, It can be prefabricated in a variety of shapes and sizes, including a device that ensures the reversible joining of the parts together and a device that ensures the stability of the entire fixator, with great flexibility. The shell-shaped orthopedic external fixator of the present invention, which can be applied to any limb of any patient, has the support cushion partially protruding from the end of the shell half and these protrusions. At either end of one half at a given height or It is characterized by being present at only one of the two ends.

According to the present invention, this orthopedic fixator, which is composed of two shell halves and has great adaptability to an impaired limb, has in one preferred embodiment one shell half. Is mirror-symmetrical to the other half of the shell.

The fixator is preferably constructed of PVC, high impact polystyrene or other reinforced plastic with the required physical properties.

The aforementioned cushions and / or grooves and / or air holes are the same or different from one another with respect to their size and shape.

The cushion (flexible portion) is made of rubber, foam rubber or foam plastic. These cushions can be attached to the shell halves by adhesive.

A device that ensures that the edges of these two shell halves fit together exactly to ensure that they are irreversibly joined together is at the edges of these shell halves. It may consist of connecting the holes on the provided flanges to each other. Furthermore, the device for ensuring the stability of the entire fixator can consist of a self-locking belt device wrapped around the shell half or a belt device provided with reversible interconnection means.

Compared with conventional casts, the orthopedic fixator according to the present invention, which is composed of two shell halves, which has great adaptability to injured limbs, has the following great advantages: Simple structure and low cost, 75% reduction in waiting time, 80% reduction in preparation time, reduction of working personnel, ventilation of the injured limbs through the provided air holes, nursing and medical care Easier access to limbs that have been impaired for reasons or opening, possibility of re-use of orthopedic fixators, cautions the patient must give to the cast and risk of misuse of the cast It has the advantages of reduced psychological problems and related problems, and easier attachment of the fixator to damaged limbs.

As previously mentioned, such a shell-shaped orthopedic fixator has many advantages and can be easily applied to a variety of specific limbs. Other advantages of the orthopedic fixator of the present invention will become apparent in the detailed description which follows, and in particular, the fixator of the present invention can be configured in a variety of shapes and sizes, and may be used by relatively unskilled workers in patient It can be easily attached to the limbs.

【Example】

 The objects, features and advantages of the present invention will be better understood by referring to the accompanying drawings in which like parts are designated by the same reference numerals.

Referring to FIGS. 1 and 2, an orthopedic fixator for a human foot is indicated generally by the numeral 1. The orthopedic fixator has an outer portion that includes an edge and a flange. The orthopedic fixator is configured to include two mating shell halves as shown. The orthopedic fixator 1 is configured to include an air vent 3. These two shell halves are assembled by a self-locking belt 4. The inside of these half shells is configured to include a cushion 5 of foamed rubber. Channels or grooves 6 form air passages along the length of the fixator. The cushions at both ends of the shell half shown on the lower side of FIG. 2 form protrusions 7 at the height of the cross section. A hemispherical heel support 8 is shown attached to the heel portion of the foot immobilizer to protect the heel from impact and improve balance.

In practice, when the fixator is mounted on the leg and correctly positioned on the fracture, the protrusion 7 is the most comfortable and holds the pressing force accurately to both half shells of the fixator. It gives the possibility of adapting the parts, which must be wound by a self-locking belt, to the particular part which is impaired. It has ridged contact to the fixator as well as to the skin. The function of the air holes 3 and grooves 6 is to aid in the continuous flow of air into the fixator and ultimately to the continuous sweating of the limbs.

[0018]

[Effect of the device]

 Since the present invention is configured as described above, there is no inconvenience of transporting and supporting a heavy cast, physical discomfort and psychological problems, and it is possible to observe the treatment process and breathe the limbs. A high performance orthopedic fixator can be provided.
