Description

FINGER RE-ADAPTATION ORTHESIS
Cross-Reference to Related Applications
[0001] The present patent application claims the benefits of priority of United States Provisional Patent Application No. US 61/783,092, entitled "Orthesis used for the re- adaptation of the fingers" and filed at the United States Patent and Trademark Office on March 14, 2013.
Field of the Invention
[0002] The present invention generally relates to orthesis and prosthetics. More specifically, the invention relates to an orthesis for the re-adaptation of a hand for which patients have suffered ligaments, muscles, and/or skin injuries.
Background of the Invention
[0003] The U.S. Pat. No. 3,967,321 discloses an orthopedic support device and method which employ an arm splint of an orthosis attached to the forearm of a cervical 6 - cervical 7 motor lesion quadraplegic. The arm splint includes a thumb flange for holding the thumb of the patient, and a pivoting finger trough for holding the first and middle fingers of the patient. A Bowden cable is connected to the pivoting finger trough and is operated by a motor to cause the pivoting finger trough to pivot to close towards the thumb flange to provide finger prehension so that the patient can grasp objects. The motor is controlled by control circuitry that is operated by the patient touching a touch sensitive contact that is typically mounted on the arm rest of a wheelchair. Such an orthesis is cumbersome, required a motor and is generally high cost to produce. [0004] The U.S. Pat. No. 4,447,912 discloses an orthopedic support device and method which employs a prosthetic device to enable persons incapable of proper control of their fingers to manipulate objects such as brushes, pencils, or toys. It resembles a partial glove, covering only the palm, held in place with straps around the back of the hand. It uses hook and loop pile (Velcro for example) both to fasten the straps to the body and as a patch on the palm side to which objects fitted with mating pile can be attached. Such a prosthetic is not suited for supporting exercises of the fingers. This prosthetics is mostly used to help the user function as an aid but does not assist in his recovery by forcing the flexion of the joints. [0005] The U.S. Pat. No. 4,716,892 discloses an orthopedic support device and method that employs an orthopedic support device for body portions. The device comprises a pliable wrap that encircles a member of the body of a patient and further comprises a pocket adapted to receive a thermo-formable bracing element. A pocket-forming panel is secured only partially to the wrap for allowing the wrap to stretch more readily to mold with contours of the body portion. Such an orthopedic support device is lacking the ability to apply forces in the flexion direction of the joint or in opposite directions.
[0006] The U.S. Pat. No. 5,766, 142 discloses an orthopedic support device. The hand orthosis has a base member supporting the palm and fingers of a patient. The base member has a cover which extends at least over the finger support area. A plurality of spaced parallel forwardly extending finger separators extend outwardly from said cover to form a plurality of finger channels therebetween. Although this orthopedic support device provide a resistance for exercising, it lacks adjustability features. As such, in order to vary the resistance, the user must replace the orthosis.
[0007] The U.S. Pat. No. 6,238,358 discloses an orthopedic support device and method which employs a combined, reconfigurable, multi-purpose external orthopedic fixation device and multi-functional prosthesis, for use alternatively as an external orthopedic fixation device for providing support and/or traction for a sprained, fractured, or broken limb and as an artificial prosthesis for providing both substitute elementary limb functionality and substitute multi-purpose specific task functionality of a limb, especially an upper limb, such as a finger, hand, wrist, forearm, or elbow. This orthopedic support device provide flexibility in the system, however, it lack the proper support to all the parts of the hand and finger.
[0008] The U.S. Pat. No. 8,348,810 discloses a movement device for flexing and/or straightening a joint of a user. Such device includes a first anchor element adapted to be positioned adjacent a jointed appendage of a user at a first position. A second anchor element is adapted to be positioned about the jointed appendage at a second position. The jointed appendage is located between the first anchor element and the second anchor element. A spring member is positioned between the first and second anchor elements wherein the spring member is fixedly secured to the second anchor element and moveable through the first anchor element to thereby allow the spring member to bend about a joint of the appendage when said appendage is flexed. The spring member is configured to exert bending forces in opposition to working muscles of the user to straighten or flex the joint of the appendage.
[0009] None of the system provides an easily adjustable orthesis or prosthetic enabling proper exercising of a user. In addition, none of the disclosed systems provide dynamic adjustment of the orthesis permitting a variable tension to be applied between finger and a wrist of a user. There is thus a need for an orthesis that is able to provide a solution for training of the finger and hand joints in an easy manner while allowing a large degree of adaptability concerning the size and the tension applied. Furthermore, the solution provided by the prior art are complex and require extensive measurement to ensure proper fit of the prosthetic while also being high cost devices. As such, most available solution may not be suitable for all the population.
[0010] The present invention will provide a solution that overcomes the shortcomings of the prior art systems while providing an economical alternative to costly devices.

In addition, such construction eases the assembling of the finger re-adapatation orthesis and reduces the labour requirement and associated costs. The enhanced flexibility and simplicity of use and installation of the finger re-adaptation orthesis allows a significant reduction in tooling and ongoing maintenance costs. [0018] A practical example of the flexibility provided by the present invention resides in its ability to allow both the bracelet and the glove to have different sizes while still being able to function together. For instance, a user may request a large size glove to be combined with a small bracelet. Prior orthesis systems generally produced orthesis as unitary orthesis, hence sensibly reducing the flexibility in components sizes and adjustments while significantly increasing production costs. This flexibility in adjustment of the finger re- adaptation orthesis therefore minimizes additional assembling costs by simplifying the core components of the orthesis. Given the separable objects principle between the hand and the forearm, the finger re-adaptation orthesis is ideally suited for the preceding application, as well other applications that require flexibility in association with reduced production costs.
[0019] According to another aspect of the present invention, the modularity, the adaptability and the flexibility of the orthesis, allow the finger re-adaptation orthesis to function even in instances where the user has less that fingers per hand. As such, a user with 4 or less fingers per hand would still be able to use the orthesis. In the latter case, the user would simply have to remove the flexion wires that are attached to the missing fingers. Such modification may be simply achieved because the design of the present invention allows it..
[0020] The finger re-adaptation orthesis, according to further aspect of the present invention, may be quickly adjusted to fit different specifics cases without the need of having an overly complicated consultation with the user.
[0021] Similarly, the mechanical features of the finger re-adaptation orthesis enables the orthesis to tolerate more flexion force than existing systems. This is done via a ratio system which enables the user to easily turn the levers to create a flexion, while only creating a strong but small movement on the fingers.
[0022] In addition, the orthesis typically uses a mechanism and a pulley system to create key and precise exercises to the fingers affected for re-adaptive purposes. Currently only two exercises are required for the patient to get a full recovery over time. In general, these two exercises are quite distinct from each other, therefore they generally require two different type of orthesis to be able to perform these exercises. However, the present invention generally allows the two exercises to be performed by using a mechanism that is able to fluently perform both exercises.
[0023] One skilled in the art shall understand that the finger re-adaptation orthesis of the present invention provides huge improvements to the orthesis and prosthetic field for finger re-adaptation. The present invention thus provides economical savings, additional previously non-existent safety features, while being more flexible to the patient's needs, and provide an increased flexion.
[0024] Other and further objects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

[0034] A novel finger re-adaptation orthesis 2 will be described hereinafter. Although the invention is described in terms of specific illustrative embodiment(s), it is to be understood that the embodiment(s) described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.
[0035] Now referring to Fig. 3, the invention relates to an orthesis 2 for controlling the angle 4 of the fingers 6 relative to the hand 8. This orthesis 2 generally comprises a bracelet 10 and a glove 12. The glove 12 size is independent to the size of the bracelet 10. In that regard, the orthesis 2 is modular. Accordingly, any bracelet 10 sizes may function with any glove 12 sizes.
[0036] Still referring to Fig. 3, in the present embodiment, the glove 12 is generally fitted with at least one, preferably a plurality of attachment members or anchors 14, configured to secure one end of a flexible elongated member 16 typically attached on a bracelet mechanism 18. The glove 12 is made from flexible material such as fabrics, Kevlar, nylon, polymer, or any material having a suitable strength to withstand the tension thereof while providing the desired flexibility. The glove 12 is also preferably made longer on the wrist 20 or forearm 22 to cover the section wherein the bracelet 10 would typically be attached thereby allowing the bracelet 10 to secure the glove 12. [0037] In the present embodiment, the bracelet 10 generally comprises a band 26 and a securing mechanism 28 such as Velcro, allowing the bracelet 10 to be held on a patient's wrist 20 or forearm 22. The bracelet 10 also typically comprises a flexible elongated member 16 attachment mechanism 30 allowing the flexible elongated member 16 to be secured to the bracelet 10 attached on a wrist 20 or forearm 22. In addition, the bracelet 10 comprises a tightening mechanism 32 providing a means for tightening a flexible elongated member 16 such as a string having one of its extremities attached on the bracelet 10 or on a component of the tightening mechanism 32 and the other extremity attached onto the glove 12 at a securing location preferably on a finger 6 section. The bracelet 10 may be made from fabric, polymer, nylon, Kevlar, rubber, or any suitably strong material providing the desired flexibility.
[0038] The bracelet 10 provides a base for the control or tightening mechanism 32 to create the movement of the fingers 6 through one or more flexible elongated member 16 such as a string, a cable, a lace or any other elongated member made with resistant flexible material, attached to at least one designated location on the glove 12, preferably on one or more finger 6. The tension created on the strings by the tightening mechanism 32 of the bracelet 10 forces the rotation of the required joints 38. Furthermore, the control or tightening mechanism 32 may further comprise a locking system allowing the strings to be held in place at a desired tension.
[0039] In a preferred embodiment, the tightening mechanism 32 generally comprises an anchor 42, a pulley mechanism 44, and an actuating level rotating a gear 48 further rotating a cylindrical member 50. One end of the flexible elongated member 16 is typically attached to the anchor 42. The anchor 42 is typically integrated to the cylindrical member. The ratio of the size of the gears 48 generate a tension substantially greater than the force applied by the user. As such, the tightening mechanism 32, also referred as the tensioning mechanism 32, allows a user to apply a substantial level of tension using minimal force on a finger 6 or a hand 8 joint without further assistance. Understandably, the use of a failsafe mechanism preventing the user to apply tension over a certain level will be of significant use in preventing injuries from over tensioning of the finger 6 section relative to the wrist 20. The failsafe, also referred to as tension limiter works by setting a "spring" to a certain pressure limits. Once a pressure applied to the spring become higher than what is currently set, the spring will trigger a mechanism causing the system to make prevent any additional tension to be added to the system. As such, the tension limiter will disable the incremental tensioning of the tensioning mechanism 32 until the tension is reduced back to level below the pre-set limit enabling the system to increase or decrease the tension again. The flexible elongated member 16 is typically configured to exert bending forces to straighten or flex the joint of the finger
[0040] The Figures 3 and 4 display the typical positions of for which the basic system may be configured to work. The following presents three (3) possible examples of the system in accordance with the principles of the invention.
[0041] Example A
[0042] Referring to Figs. 1 and 2, the lines 70 are positioned over or under each joint and within the palm. The lines represent possible points where one or more attachment member 14 may be placed to either hold a string or let strings pass through the one or more opening 74 in the attachment member such as a ring anchor 54. Now referring to Figs. 5 and 6, an example of the present embodiment A is shown. A string may be attached to a ring anchor 54 if required while a string may also be passing through the opening 74 of a ring anchor 54.
[0043] In addition, in another embodiment, the finger re-adaptation orthesis 2 may further comprise intermediate anchor elements permitting a more pronounced flexion of the finger joint. [0044] In another embodiment, one or more string may be attached directly to the glove 12. Furthermore, a ring anchor 54 may be sewed to the glove 12 and one or more string may be attached to the ring anchor 54.
[0045] In yet another embodiment, the glove 12 and bracelet 10 could be a unitary system such as a glove 12 having a securing mechanism 28 allowing one portion of the glove 12 to be secured to the wrist 20 or forearm 22 of the patient. While this embodiment would potentially reduce of the level of adjustability, such embodiment may be desirable to provide the same training and exercise abilities while overcoming major shortcoming of the prior art exercise prosthetic systems. [0046] Example B
[0047] Now referring to Figure 3, a system placed on the forearm 22 in accordance with the principle of the present invention is shown. Such system creates a tension on the strings attached to or on the fingers 6 or finger joints. Such tension is typically created by pulling the strings and then locking them in place to hold the tension at a desired level. Another example of this type of system is shown at Figs. 3 and 4. This tensioning mechanism 32 pulls the string via a rotating key 80 located on or into the securing mechanism 28 and holds them in place via a locking system 40 such as, but not limited, to locking system used in a pen.
[0048] Example C [0049] Now referring to Fig. 2, a system positioned on the dorsal side of the forearm to provide a similar level of training compare to the examples A and B is shown but for the opposite direction of the joint. Such a system may also lock the one or more strings 16 attached to the fingers 6 portion of a glove 12, more specifically, on the dorsal side of the fingers 6. This locking of the one or more strings 1 is done using a locking mechanism 40 may similar to the locking system of a pen. However, although some examples of the locking mechanism 40 are shown, one with the skills in the art would understand that other embodiments may feature any other systems allowing the securing or locking of a string.
[0050] Summary of exercises
[0051] An orthesis 2 in accordance with the present invention may generally be used by a patient in order to improve his fingers' 6 or hand' 8 mobility. For instance, the present finger re-adaptation orthesis 2 could be used to improving the flexion of the fingers 6. [0052] Exercise MCP
[0053] During a MCP exercise, a user, such as the patient, a physician or an occupational therapist, typically rotates the key 80 for which the one or more strings 16 are attached between metacarpophalangeal joint 62 and the proximal interphalangeal joint 60 attached to a locking mechanism similar to the one presented in Example B. By doing so, the metacarpophalangeal joint 62 is rotated. In a preferred embodiment, the strings are attached to or near the portion of the glove 12 over the proximal interphalangeal joint 60.
[0054] Exercise PIP
[0055] In an PIP exercise, a user, such as the patient, a physician or an occupational therapist, must first lock the strings 16 attached to a locking system, such as the system presented in Example C. Then the user may rotate the key 80 for which the strings 16 are attached to the tip of the fingers 8. Doing this will create a rotation on the proximal and distal interphalangeal joint 60. In another embodiment, the strings 16 may be attached between the distal interphalangeal joint 60 and the tip of the finger 8 on either the dorsal or the ventral portion of the glove 12.
[0056] The finger re-adaptation orthesis 2 may further allow the user to attach the elongated member 16 to more than a single attachment member 54 thus allowing the user to exercise multiple fingers 6 simultaneously when such an exercise is desired. [0057] Now referring to Figs. 6 and 7, the method for using the product generally comprises of fitting the glove 12 to the hand of a user, securing the glove 12 and the bracelet 10 to the user's wrist 20 or forearm 22. The method may further comprise the steps to select a glove 12 adapted to the size of the hand 8 and/or fingers 6 of a user and selecting a bracelet 10 adjusted to the wrist size of the user. The user must attach the elongated members 16 to both the glove 12 and the tensioning mechanism 32. The user tightens the tensioning mechanism 32 to the desired strength. Upon reaching the desired strength, the user may lock the tensioning mechanism 32 as to retain the specific tension for until the user decides otherwise. The user typically unlocks the tensioning of the tensioning mechanism 32 and changes the tension to a higher or lower value depending on the prescribed exercise. The user may repeat the exercise until the tensioning of the finger 6 portion has reached the desired level. The user may further repeat the exercise with another finger 6 or execute the exercise on a plurality of fingers 6 at once. [0058] Also, upon completion of the tensioning of the finger 6 toward the palm of the hand 8, the user may use the orthesis 2 to exercise the finger 6 and hand 8 toward the back of the hand 8. In such an exercise, the method further comprises the step to first remove the tension created during the preceding exercise by unsecuring the elongated members 16 from the tensioning mechanism 32. Then, the bracelet 10 and/or the tensioning mechanism 32 are rotated toward the back side of the hand 8. In order to lock the fingers 6 to a new position, the user must secures the elongated member 16 to both the glove 12 designated spaces and the tensioning mechanism 32. Upon securing the elongated member 16, the user applies tension up to the desired level using the tensioning mechanism. Again, the user may choose to lock the tensioning to a desired position allowing the orthesis 2 to remain in this position for a desired time period.
