Description

[Detailed description of the invention] , Prototype - Femoral correction device Technical field The present invention relates generally to knee braces. More specifically, the present invention Supports and stabilizes the knee, including abnormal lateral subluxation of the knee during knee joint movement The present invention relates to a device capable of resisting.

Background technology Anterior knee pain (i.e., pain in the front part of the knee) is the most common complaint among patients visiting knee specialists. This is one of the most common symptoms. Many of the causes of such pain are caused by the original kneecap (kneecap). It is a disease of the protofemoral joint associated with instability. Instability of solubility is usually caused by Occurs laterally (i.e., away from the opposite leg) and is known as ``subluxation of the original'' or ``original subluxation.'' It is also called ``excessive movement of the original garment''. This patient with knee abnormality The muscles and keys that hold the garment in its proper position within the knee may be misaligned. , very loose or flaccid. This condition is caused by abnormalities in growth (generally , young children) or damage to the muscles and/or keys that attach to the attachment. Ru.

In this state, the original garment is placed extremely loosely, and as a result, during rotation of the knee joint in flexion/extension. (i.e., when the leg makes a normal "bending" motion at the knee joint), the posture of the original deviates from its normal position. Such postural deviations are usually caused by heavy loads while rotating the knee. Joints stretch under stress during strenuous physical movements, such as when supporting a body. As a result of increasing

Subluxation of the garment is not only extremely painful, but also prevents the garment from being properly oriented. When not in position, the knee also bends (flexes) under the load placed on it. It becomes easier. Furthermore, as a result of continuous or frequent abnormal displacement of the deposit, There is a risk of significant degeneration of the surrounding knee structures.

Traditional treatments for insecurities include muscle rehabilitation, drugs, and/or Often includes movement correction. Additionally, those skilled in the art will be able to assist in the treatment of dye instability. We have developed as many types of knee supports as possible. Such a support is extremely hourly. There are various types ranging from extremely complex to extremely complex, and they are used to some extent to treat instability of the dye. It has been effective.

Simple knee sleeves are often used to provide native static support. This space The leaves are generally made of elastic material and prevent the deposit from protruding through them. Comes with an opening. Therefore, when positioned, the sleeve rests on the knee. Provides force and assists in maintaining the deposit in proper alignment.

Other prior art orthotic devices include submorphic straps. The strap The wrap wraps around the knee to support the garment during movement of the knee joint.

Still other prior art devices utilize an elastic sleeve and a plurality of elastic straps. Some devices include a support pad that is held in a lateral position relative to the original adhesive. This vessel The tool applies a force that displaces the original garment inward (i.e., a force directed toward the other leg). The purpose is to maintain constant pressure during knee flexion, extension, and rotation movements. do.

Some prior art devices have had some success in treating deposit instability. However, the exact function of many devices is unclear. For example, some followers Prior art devices are useful for pain relief for a number of reasons. This device is attached to the knee The warmth it provides is therapeutic. Similarly, the sensory feedback can also be changed to This can reduce patient discomfort. Similarly, changes in blood flow Another effect of many devices is that they can be These non-special mechanisms helps explain the effectiveness of some prior art prototypical orthotics.

Additionally, many existing orthotics tend to shift on the user's knee during knee motion.

Naturally, such misalignment will cause the orthotic to become misaligned, thereby causing the orthotic to become unaligned. The functional effectiveness of is significantly reduced.

Additionally, when the knee joint is hyperextended, the material slips deeper into the prototype cavity. There is an inherent property of the knee. In such cases, as a result of the structure of the existing orthodontic appliance, slides under the orthodontic appliance and rotates under the appliance. As a result, orthodontics generally becomes inoperable.

Additionally, the mechanical functionality of existing devices is limited to the lateral side of the adhesive in patients who have problems with adhesive followability. It is thought that it merely imparts an inward force to the surface. This feature supports healthy living. This is thought to be based on physical-mechanical principles, but this may be one of the causes of the instability of the doping process. It's just a treatment. Assuming that this function is applicable to the treatment of other causes as well. No evidence has been confirmed. Therefore, the stability of doping is more completely improved and promoted. Orthodontic appliances that do this are considered to be an issue.

BEST MODE FOR CARRYING OUT THE INVENTION The stability of the anchor is determined by dynamic (muscle), geometric (bone) and static (I) components. It is caused by working together. Any or all of these components are missing In this case, the original dyeing becomes unstable. Therefore, an effective self-adhesive straightening device can address all of these It is necessary to improve and accelerate the functionality of the components as much as possible.

Dynamic (muscular) stability is best achieved through proper neuromuscular training. . However, muscle action can be achieved by controlling the femoral-tibia flexion angle. It is also possible to improve this through the installation. By preventing overstretching, muscles has a larger shaft that controls internal rotation of the tibia, thereby reducing rotational forces on the knee. This power is given. By preventing overstretching, muscle function improves, and The repulsive force of the prototype femur joint also improves.

Similarly, geometric or bony restraints can be improved by preventing hyperextension. It is possible to In some cases, the degree of harmony of the original femur is determined by the degree of flexion (bending) of the knee. This can be improved by increasing . Also, due to the anatomical shape of the knee, The increased flexion results in a larger surface of the implant being in contact with the femur.

Controlling the medial and lateral rotation of the knee joint also directs geometric (bone) restraint forces. It is useful for increasing If the medial rotation at the knee is large, the lateral movement of the original garment will be If passive subluxation occurs and lateral rotation is large, it may be a secondary effect of muscle contraction. Active lateral subluxation of the original adhesive occurs.

In connection with the above, a prototype of the present invention, designated generally by the reference numeral 10 - of a femoral correction device. One preferred embodiment is illustrated in its entirety in FIG. As shown, orthodontics The position 10 is placed around the knee area of the user's leg and the lower part of the user's thigh and It is designed to cover the entire knee joint, including the upper part of the lower leg. Orthodontic device flO resists abnormal lateral subluxation of the knee as the knee approaches extension. An abutting system (see fixing plate 16 in FIG. 2(a)) is provided. Also, correction The device 10 controls the medial-lateral rotation of the knee joint while allowing the orthotic device to rotate in both directions. A single hinge system (see hinge arm 28.29) for ease of operation. the tibial and femoral shell system (see cuff 23.24) attached to the We are prepared. The hinge system includes an overextension stopper that prevents overextension of the glue. Furthermore, the original femur is Improve the degree of harmony.

The components of the invention generally described and illustrated in the accompanying drawings may be of various different shapes. It will be readily understood that it is possible to arrange and design the in this way , the following more detailed description of the embodiment of the invention shown in FIGS. 1-7(b) includes: It is not intended to limit the invention as claimed, but merely to limit the scope of the invention as claimed. It is merely illustrative of the presently preferred embodiment.

As best illustrated in FIGS. 2(a) and 2(b), the orthodontic device 10 includes a A sexual sleeve 11 is provided, to which a support orthotic device 12 is attached. (See Figure 5). The sleeve 11 is fixed to the elastic sleeve 11. A fixing plate 16 is provided. The fixation plate 16 extends from the sleeve 11 and extends from the user's a pair of straps that pass around the medial and rear sides of the legs and connect to the support orthosis 12; 14 or otherwise operably coupled to the strap 14. .

As shown in FIG. 2(a), the elastic sleeve 11 is fitted around the user's legs. sized for a snug fit, the sleeve being somewhat extended by the legs; The dimensions are such that the elastic force of the sleeve 11 can hold the sleeve in the proper position on the leg. It is.

The sleeve extends above the user's thigh and below the top of the user's lower leg. It is desirable that the length be sufficient for the be made of a material that can be stretched and contracted in all directions (rather than a stretchable material) is desirable. An example of such a material is the Italian Sport Medizine (Spo rt-Med Engineering 2□. ) is a registered trademark of Vitalo (IIITALO). It is knowledge.

As best shown in FIGS. 2(a) and 4, the elastic sleeve 11 is A pair of slit-shaped openings 1 through which the straps 14 of the fixed plate 16 can pass. It is equipped with 5. The strap 14 extends approximately 3/4 of the distance around the user's leg. of sufficient length to extend and attach to the support orthosis 12 in the manner described below. It is.

As shown in FIG. 3, the fixed platework 6 forms a substantially concave tibial contact surface 19 therebetween. A pair of arms 17 are arranged in a substantially parallel spaced relationship to achieve Ru. The fixing plate 16 also has a substantially curved arm so as to adapt to the degree of curvature of the knee joint. Optionally, an extension 18 is provided extending from 17. The extension part 18 is Protect the lateral part of the knee from damage or accidental contact with the support orthosis 12. It works to The extension 18 also positions the fixation plate 16 at its precise location around the user's knee. Helps lock and secure in place.

As best illustrated in FIGS. 2(a) and 2(b), the fixing 16 (shown in dotted lines) ) is placed around the lateral side of the user's knee, and its concave contact surface 19 is placed adjacent to the sideways portion of the original model 33 and more or less conforms to the sideways portion, and its extension Long section 18 extends around the lateral side of the user's knee joint. Importantly, the following As will be further explained, the fixing plate 16 applies force to the lateral and slightly lower surfaces of the master model 33. and are designed and used in such a way as to maintain the proper position of the original. It is to be able to do so. For this reason, for example, the model can be placed above the original at an angle of approximately 30° from the horizontal line. The fixing plate 16 can be positioned relative to the user so as to apply a lateral force to the user. I can do it.

The fixing plate 16 of the present invention is made of a semi-rigid, semi-flexible material. Ru. That is, the fixation plate 16 can be easily positioned at its precise location around the user's knee. Stiff enough to hold its shape as possible and the anatomical shape of the knee It is semi-flexible to allow it to fit. used to form the fixed plate 16. The preferred materials used are silicone and/or polyethylene. For example, fixed Plate 16 can be formed from a polyethylene plate coated with a soft silicone material. Ru. However, any semi-rigid, semi-flexible material with similar properties can also be used. It is. The materials used are as measured by ASTM test method D-2240-86. , Shore durometer hardness is preferably 15 or less.

As shown in FIG. 4, the inner surface 22 of the flexible sleeve 11 has a A cavity 20 can be provided having an opening 21 into which it can be inserted. The blank space 20 serves to hold the fixed plate 16 in its correct orientation relative to the sleeve 11.

The cavity 20 is provided with a fixation plate during the manipulation and insertion of the sleeve 11 into position around the knee. 16 in its proper orientation, the cavity 20 allows the user to hold the sleeve 11 in its proper orientation. Most useful when mounted on legs. In a preferred embodiment, the cavity 20 is , is shown as a means for holding the fixing plate 16, but the fixing plate 16 uses adhesive. or other known methods such as sewing in place or using mechanical fasteners. It is conceivable to hold it in the sleeve 11 in any of the following ways.

When the sleeve 11 is accurately positioned on the user's leg, the slit in the sleeve 11 15 are centered directly above and below the master mold 33. The strap 14 is a plate through the slit 15 until the slit 17 is disposed substantially adjacent to the slit 15. . In this position, the concave contact surface 19 of the fixing plate 16 rests against the lateral side of the user's original 33. touching and completely surrounding the sides.

In the method shown in FIGS. 2(a) and 2(b), the user places the sleeve 11 on the leg. Once determined, the supporting orthotic device 12 is attached to its outer surface 13 in the manner illustrated in FIG. Position. The support orthodontic device 12, as explained below, It serves to provide a rigid support to which the wrap 14 can be attached.

As illustrated in FIG. It has an upper cuff 23 and a lower cuff 24 made of material. Each of the cuffs 23.24 follows the well-known cuff design and features padding on its inner surface for comfort to the patient. Rukoto can.

The use of such a rigid or semi-rigid cuff 23.24 will be discussed in more detail below. As will be clear, the orthodontic device 10 significantly improves its ability to prevent excessive elongation. I can do it. Without such a cuff, all hyperextension arrest features utilize flexible tissue. must be connected to the user's leg using the Ru.

Additionally, the upper cuff 23 and lower cuff 24 may extend along a substantial portion of the user's leg. It is an important feature of the invention that the dimensions are such that: These cuffs23. 24 along at least 50% of the circumference of the user's leg portion to which the cuff is attached. It is desirable to make it expand as follows. Support orthotics with cuffs of this size 12 attaches more securely to the user's leg than those with smaller cuffs Is possible. Additionally, the larger the cuff 23.24, the more likely it is to avoid accidental errors during use. risk of rotation relative to the user's leg due to impact or other forces applied to the becomes even fewer.

Each of the upper cuff 23 and the lower cuff 24 supports the support correction device 12 on the user's body. A strap 25 that is fixed to the leg and a corrective device 12 that supports the original fixing strap 14 A buckle 26 that is fixed to the. In this way, the strap 14 It can be attached to the buckle 26 of the holding correction device 12, and the fixing plate 16 The internal pressure applied to the user's master form 33 can be adjusted. Advantages of the present invention In this embodiment, the strap 14 and buckle 26 are shown, but the fixing plate is 16 directly to the supporting orthotic device 12 and The attachment mechanism is considered to be within the scope of the present invention. For example, buckle 26 Alternatively, it is also possible to use snap fasteners, Velcro fasteners, etc. . Additionally, if desired, depending on the nature of the particular orthodontic device desired, straps may be used. 14 can be formed of either a non-elastic material or an elastic material.

Each lateral side of the upper cuff 23 and lower cuff 24 has an extension arm 27,28, respectively. Both arms are attached to a hinge 30. Support orthodontic appliance 12 When accurately positioned on the user's leg, the arm 27.28 will be placed on the side of the user's leg. so that the axis of rotation of the hinge 30 is aligned with the flexion/extension of the user's knee joint. It is arranged approximately coaxially with the long rotation axis and can follow the hinge movement.

Each of the arms 27, 28 is adapted to secure the straps 25 of the support orthosis 12. It is equipped with a buckle 29 for use.

As best illustrated in FIGS. 7(a) and 7(b), the support correction device 12 is The engine 30 includes a locking surface 31 of the arm 27 and a locking hub 32 of the arm 28. ing. When the hinge is in the bent position (FIG. 7(a)), the locking surface 31 and the locking The tabs 32 cannot engage with each other. However, if the user's knee is in full extension When approaching the position (FIG. 7(b)), the locking hub 32 comes into contact with the locking surface 31 and the knee This prevents further elongation (over-elongation). This means that the user's knees are approximately 15 to 2 It is desirable that this is done when the data is expanded to 0.00.

The orthodontic device 10 of the present invention must be adapted to the leg dimensions of the user to which it is applied. Therefore, its various structural components can be grouped together to make them applicable to different users. It is expected to be formed with different dimensions.

Another embodiment 110 of the orthodontic device of the present invention is illustrated in FIGS. 8-10.

As shown, the cuffs 123, 124, when positioned as described above, It is formed in a spiral shape around the leg of the person. Similarly, connection strap 125 spirals around the user's legs, and as best illustrated in FIG. Attached to Kru 129. For example, the strap 114 may be sewn together to prevent slippage. The strap 11 is operably coupled to a fixation plate (not shown) through the strap 111. 4 is attached to cuff 123,124 by buckle 126. In Figure 10 As best illustrated, the buckle 126 is connected to the initial point of the strap 125. It is desirable to position it in a substantially straight line.

As mentioned above, the fixing plate 16 may not be provided with the protective extension 18 (see (See Figure 3). In such a case, as shown in FIGS. 8 and 9, the hinge arm 1 27.128 may be made of a suitable elastic material such as, for example, elastic plastic cushioning. It is advantageous to coat the This elastic covering is thus placed next to the user's knees. Protect the sides from damage or accidental contact with the supporting orthosis.

Referring again to FIGS. 1 to 7(b), when in use, the upper cuff 23 is It is placed in contact with the surface 13 of the part of the sleeve 11 in front of the upper leg, and its strut The cap 25 is attached to the buckle 29 through the back of the leg. Next, the strap 25 to firmly fix the cuff 23 to the thigh. Similarly, remove the cuff 24. placed in contact with the surface 13 of the rib 11 and above the front side of the user's upper leg. The strap 25 placed on the user's Pass it through the back of the leg and attach it to the buckle 29. Tighten the strap 25 and It firmly adheres to the user's upper abdominal region of the foot 24.

As shown in FIGS. 1 and 6, the fixing plate 16 is supported through the strap 14. It is integrated into the orthodontic appliance 12. Securely connect to the fixed plate 16 through the strap 14. By doing so, it becomes possible to apply dynamic force to the back of the knee 33. As shown, The trap 14 wraps around the mid and rear portions of the user's leg and supports the support orthotic device 1. 2 upper cuff 23 and lower cuff 24, and the connection of this side strap is as follows: Above the first part of the fixation plate 16, the connection of the strap on the cuff side should be below the first part on the fixing plate 16 (see Figure 6). ).

The supporting orthotic device 12 is secured to the user's leg over the elastic sleeve 11 and the strap 14 to its buckle 26, the orthodontic device 110 of the present invention generally comprises: This is shown in FIGS. 1 and 6. If desired, the elastic sleeve 11 can be The upper and lower ends are pulled away from the user's legs, as shown in FIGS. 1 and 6. It can be folded over the upper and lower parts of the upper cuff 23 and lower cuff 24. come. In this way, the elasticity of the sleeve 11 allows the supporting orthotic device 12 to 1 will tend to help it stick to its exact position relative to the 1. Also, sleeve 1 1 with the supporting orthotic device 12 holds the orthodontic device 10 together and function as an appliance and maintain proper position of the appliance throughout the range of motion of the knee. It is useful for

From the above disclosure, it is clear that the orthodontic device 10 of the present invention is accurately attached to the user's leg. At least partially, the back of the user's knee 23 is at least partially secured by the fixing plate 16 on its lateral side. It is clear that it is surrounded. The fixed plate 16 is supported by a buckle 26. fixed in its lateral position by a strap 14 attached directly to 12. (The support orthodontic device 12 itself includes a strap 25, a buckle 29, and a sleeve.) 11 folded ends ensure secure positioning against the user's legs ), the back of the user's knee 33 is prevented from moving laterally relative to the other structures of the knee.

The fixation plate 16 is fixed by the strap 14 and extends inwardly against the side of the back of the knee. This applies pressure to prevent lateral subluxation. Subluxation occurs only laterally Therefore, the orthodontic device as described in the present invention is sufficient to prevent this occurrence. Ru.

The straps 14 attach the fixation plate 16 to the arms 27.28 of the support orthosis 12. Since the position is directly fixed, the knee flexion/extension rotational movement is dependent on the function of the orthodontic device 10. Does not have any harmful effects. Regardless of the amount of bending of the knee joint, the fixing plate 16 remains precisely positioned relative to the lateral side of the Hold it in its proper direction. The tendency of the back of the knee 33 to move laterally is due to the fixation plate 16. It can be prevented.

Importantly, when the user's knee approaches full extension, the two mechanisms , and this force helps maintain and stabilize the back of the knee in its correct position, This is to reduce lateral subluxation and excessive movement. First, support When the arms 27,28 of the brace 12 move toward the fully extended position, the cuff 2 3.24, so that each strap Attaching the ends of the pipe 14 increases the distance between the points. This is the length of strap 14 is effectively shortened, thereby applying a dynamic lateral force to the i-lid through the fixing plate 16. give

Similarly, as the user's knees approach full extension, the user's thighs and calves applies pressure to the cuff 23, 24, and the locking surface 31 engages the locking protrusion 32, so that The orthodontic device 10 is locked within the extension. The correction device 10 is biased to this locked position. If the user moves the knee to further extend it, the knee will move backward from the orthotic device 10. begins to return to normal. As a result, strap 25 secures the cuff to the user's leg; The user's legs apply force to the straps 14. This tightens the strap 14 , applies a dynamic mechanical force to the lower lateral portion of the patella 33 through the fixation plate 16.

Since excessive extension of the user's knee is resisted, the back of the user's knee 33 is placed under the fixed plate 16. There is no captivation that slips away. Therefore, it is constantly in contact with the fixing plate 16 and the fixing plate This ensures that it is pressed in the lateral direction.

Referring again to FIGS. 2(a), 2(b), and 3, the extension of the fixing plate 16 The portion 18 connects the lateral side of the user's knee and the support orthosis when properly positioned on the knee. It is arranged between the arms 27, 28 of the tool 12. Therefore, the lateral part of the knee is double protection from damage caused by impact or other forces applied to the parts.

This double protection ensures that the arms 27, 28 as well as the extensions 18 of the fixation plate 16 are protected against lateral forces. This is due to the fact that it can be absorbed. Moreover, the arms 27 and 28 are arranged in the medial-lateral direction of the knee. This increases the geometric (bone) restraint of the knee.

There is no associated hinge member or hinge arm on the inside of the user's leg. This is one important feature of the orthodontic device 10 of the present invention. This is generally the back of the knee. Subluxation is important in the treatment of such patients because it occurs in both knees of the patient at the same time. Often. Therefore, the patient is required to wear the orthotic device 10 on both legs. (Each orthodontic device 10 is a mirror image of its opposite orthodontic device). The design of the present invention By using the device, the user can see that a portion of the orthodontic device 10 is placed on the opposite knee. The appliance 10 for each leg can be accommodated simultaneously without the complexity of interfering with the corresponding orthotic device. It becomes possible to use it easily and comfortably.

The invention may be embodied in other specific forms without departing from its spirit or essential characteristics. It is possible to The embodiments described above are in all respects merely illustrative and are not limiting. It should not be considered as a thing. Therefore, the scope of the present invention is not limited to the above description. It should be determined based on the description of the claims.
