Description

PREVENTIVE OTHESIS FOR TENOSYNOVITIS OF THE LONG FLEXOR OF THE FIRST EAST IN CLASSIC BALLET DANCERS

Field of the invention

The present invention relates to a device for the prevention of long flexor tenosynovitis of the first toe in people prone to acquiring said disease. Background of the invention

Tenosynovitis is a condition that causes inflammation of the tendon and the synovial membrane that covers it. Normally, this condition can be caused by high levels of cholesterol, rheumatoid arthritis, gout, high content of calcium deposits or by repeated strains and / or trauma. Repeated strains and / or trauma are caused by severe and high-impact sports activity, mainly affecting all types of athletes.

Tenosynovitis can occur in both the hands and the feet depending on the sports activity performed. In the case of certain athletes such as basketball players, soccer football, American football, runners, Taekwondo practitioners and even people who specifically practice classical ballet dance, they tend to suffer a more marked tenosynovitis in the feet, specifically in the flexor longus tendon of the first toe or hallux or the big toe presenting pain that extends to the ankle through the flexor longus tendon.

Consequently, tenosynovitis is a severe problem that affects athletes. Consequently, certain devices have been implemented with the aim of trying to mitigate the problem, such as the one described in the US patent US 9 237 962 B2 entitled "THUMB ORTHOSIS FOR STRETCHING TISSUES LIKE LIGAMENT, TENDON OR MUSCLE AROUND THE JOINT DURING BENDING OR EXTENSION STRUCTURES, AND THE ASSEMBLY OF THE UNIT" which describes a device provided by a mechanism and straps that allow to keep the foot fixed, in addition to a mechanism that only allows flexion and extension of the ankle. The objective of this device is to treat plantar fasciitis injury, which is an inflammation in the connective tissue that joins the heel (calcaneus) with the toes (joint, metatarsophalangeal). By means of said device, the aim is to stretch this tissue through static mechanisms. On the contrary, in the present invention, work is done dynamically inside a shoe, specifically a toe shoe (even in a shoe), thus achieving an impact on the metatarsophalangeal joint of the first joint, preventing injury to the tenosinov itis of the long flexor of the first toe from repetitive and high-impact movements. The present invention is dynamic, non-invasive and its mechanism works on the Golgi apparatus, the tibial muscles, as well as the peroneal muscles, in addition to focusing on the long flexor of the first toe.

On the other hand, one of the most significant differences is that the orthosis of the aforementioned patent is completely invasive, reaching up to more than a distal 1/3 of the pelvic limb.

On the contrary, the present invention is completely, light, and does not invade beyond the forefoot area (from the middle of the instep on the foot) and can go inside a shoe, working dynamically and also allowing to work in a Tenosynovitis lesion of the long flexor of the first toe.

US patent 8 007 456 B2 entitled "DUCK FOOT ORTHOSIS TO TREAT EG, PLANTAR FASCITIS, HAS ORTHOPICS FOLDABLE WITH UPPER AND BOTTOM PORTIONS, REMOVABLE SMALL WEDGE INSERT IN THE FORM OF A FLAT FOOT LOWER FORMS OF THE PART INCLUDES BOTTOM "refers to a mechanism that allows to fix the foot in a neutral way with two straps that allow the pelvic limb to be maintained There, the objective of this is to treat plantar fasciitis, problems in the Achilles tendon, as well as post-surgical hip problems by means of a night splint. On the contrary, the present invention works on abduction movements and prevents the foot from the investment is compensated and eversion is strengthened, thus ensuring that the ankle has correct muscular proprioception.

Australian patent AU2013357062B2 entitled "AN LOWER ORTHOPEDIC DEVICE OF A HUMAN, FOOTWEAR AND PROSTHESIS PROVIDED WITH SUCH A DEVICE" describes a device that stabilizes the leg musculature by means of a plastic medium. On the contrary, the present invention has materials that They are flexible and minimally invasive for the patient or athlete at the time of use or practice, giving support through a traction function that goes from the point of traction that is located at the base of the head of the metatarsophalangeal joint of the first toe to a point fixation that is found at the base of the fifth metatarsal head, thus achieving freedom of movement producing dynamic proprioceptive work for the lower limb. The device of the present invention also has advantages such as use in footwear, omission of a treatment after its use, and its mechanisms work in movements of a bduction, inversion and eversion.

On the other hand, one of the most significant differences between the present invention and the Australian patent is that the latter is totally static and is made of totally rigid materials. On the contrary, the present invention contains lightweight and flexible materials that allow dynamic work on movements, even in ballet, and with stability and support

Patent application US5472411A entitled "JOINT ANKLE ORTHOSIS WITH U = SHAPE LINKED SLEEVE AND FLEXIBLE STRAP INVOLVES THE LINK SLEEVE WITH BELT THAT WORKS UNDER THE FOOT AND TWO ANKLE RAILS CONNECTED BY A WIDE BELT BELOW THE HEEL. ON THE BACK SIDE UNDER THE ANKLE AND THE ANCHILLESTENDON EXTENSION "describes a device to stabilize and reduce mobilization of the ankle joint to prevent peroneal ligament ruptures, that is, prevent peroneal ligament rupture. The present invention aims to work on tenosynovitis of the flexor longus of the first toe, in addition to making a dynamic correction during sports or daily practice, in addition to comprising highly flexible materials and being non-invasive during use, thus avoiding the muscle compensation towards inversion and provide correct muscle proprioception.

The aforementioned patent application describes an invasive device by the straps that are attached from the medial side to the lateral side and is highly invasive when wanting to use it inside a sports shoe or when practicing a sport, while the present invention will be linked by a band of traction that goes from its medial to the lateral side, where the point of attachment of this band allows to actively stabilize and correct, and prevent tenosynovitis of the long flexor of the first toe.

The patent application US20180014959A1 entitled

"INFLATABLE HYDRAULIC AGITATOR, IT HAS BLADDER SUPPORT INCLUDING BLADDER TO CONNECT THE SURFACE PLACEFULLY IN FRONT OF THE SURFACE OF THE BLADDER SUPPORT IN FRONT OF THE SECTION OF THE PALMAR SPLINT, WHERE THE INFLATABLE BLADDER IT IS ARRANGED ON THE BLADDER CONNECTING SURFACE "describes an orthosis comprising a palmar splint section aligned with the palm of a human subject's hand and a wrist and forearm splint section extending from the palmar splint section up to a distance corresponding to at least a part of a forearm of the human subject, where the main objective of said orthosis is static immobilization by means of a forearm and wrist valve.

On the contrary, the device of the present invention works on the pelvic limb, mainly the ankle and foot, in addition to being flexible, comfortable and dynamic, but providing support towards abduction and inversion.

Patent US 9 125 786 B2 entitled "THE DEVICE FOR MANIPULATING TENDONS IN THE WRIST HAS A MANIPULATOR, WHICH IS LOCATED ADJACENT TO THE SKIN, AND TO MANIPULATE THE TENDONS UNDER THE SKIN" describes a device and a method for manipulating soft tissues, such as tendons, which use a manipulator that works in conjunction with an orthopedic device, such as a brace, one of their objectives being to mobilize the foot, wrist, elbow and knees. However, the aforementioned patent does not have tractions or mechanisms that prevent the foot from reversing. On the contrary, the present invention refers to an orthosis that works on the Golgi apparatus, allowing correct muscular strengthening, in addition to being a specific orthosis with unique mechanisms.

Brief description of the invention

The present invention relates to a device for preventing tersosynovitis of the long flexor of the first toe in people prone to acquiring said disease, for example, high-performance athletes, in which correct foot alignment and muscle reeducation in training is one of the objectives.

The present invention also aims to provide a configuration with a synergistic approach and a mechanism that allows a comprehensive treatment of a tenosynovitis lesion of the first artery, thus eliminating various conventional problems, such as, annual incidences of injury, a mal muscular work in practice, and a permanent restriction of the tendon that can functionally disable the ankle and affect the daily life of the patient and / or athlete.

Figure 6 shows the orthosis of the present invention in use.

Detailed Description of the Invention Referring to Figure 1, an extended main body 1 of the orthosis 5 of the present invention is shown, wherein the main body 1 is made of an elastic type fabric material. The main body It is comprised of an upper portion 6 and a lower portion 7, both portions 6, 7 having a rectangular configuration, the upper portion 6 being smaller than the lower portion 7 in order that the upper portion 6 can be coupled. In figure 1, it is also possible to observe an imaginary dividing line 8 which aims to show the way in which the main body 1 is bent or bent.

Stretch-type fabric material can be selected from, but not limited to, natural rubber, spandex or lycra, butyl rubber, fluoroelastomer, plaintimers, ethylene-propylene rubber, styrene-butadiene rubber, chloropene, nylon, among others. A person skilled in the art will understand that the color of the elastic type material can be any.

Now, referring to figure 2, the main body 1 can be seen bent symmetrically in half through the imaginary dividing line 8 shown in figure 1. When the main body 1 is bent, the upper left side 9a joins the upper right side 9b by means of upper seams 12, while the lower side lia is joined to the lower right side 11b through the lower seams 10, both seams 10, 12 extending longitudinally from point A to point B as be ours in figure 2.

As can be seen from figure 3, the traction band 4 is shown, which is made of an elastic type material, which can be of the same material as the main body 1 or of another material. The traction band 4 is joined by a longitudinal seam 1.3 which forms a traction point, which extends * from point A to point B, to an upper rear portion of main body 1 as can be seen from figure 4 (see also figure 5). The opposite end of the traction band 4 comprises a point of attachment or connection 14 type sailboat.

The main body 1 further comprises a fixing point 3 with a rectangular or quadrangular shape, which is attached to a lower front portion of the main body 1 by means of fixing seams 15, the fixing point 3 being opposite the traction band 4. The clamping point 3 is adapted to receive the attachment point 14 of the traction band 4, wherein the arrow shown in figure 4 shows the complete movement that the traction band 4 makes from its disconnected state to its connected state.

Referring to Figure 5, a rear view is shown in which the pull band 4 is attached to the upper portion of the main body 1 by the longitudinal seam 13, thereby forming a pull point as previously described.

Figure 5 shows the orthosis 5 of the present invention, where it can be seen that the traction band 4 crosses from the first toe of the foot (big toe) to the point of traction formed by the longitudinal seam 13 that prevents the injury of flexor longus tenosynovitis of the first toe or gives relief to this condition.

The seams described here are reinforced in order to aid the traction of the traction band.

It is noted that, in relation to this date, the best method known to the applicant for putting the aforementioned invention into practice is the one that is clear from the present description of the invention.
