[0002] The wrist and hand orthosis, as a commonly used device for fixing and protecting, preventing and treating wrist and hand joint diseases, is usually shaped by directly covering a heated low-temperature thermoplastic plate on the affected limb.

[0003] At present, the control method is commonly used in the industry to shape the wrist and hand orthosis, that is, the maker holds each joint with one hand to keep the affected limb in a suitable position, and shapes the plate with the other hand, and then waits for the plate to cool and harden and finally forms the wrist and hand orthosis product. In this regard, the inventor believes that when shaping the wrist and hand orthosis in this way, the actual operation process is difficult to hold each joint manually, often because the muscle tension of the affected limb is too high, the hand shape difference between the patient and the maker is too large, the patient cannot fully cooperate with the production, and other reasons. In addition, the cooling speed of the plate is fast, so that the produced orthosis cannot keep the affected limb in a suitable position, not only leading to the fact that the affected limb cannot achieve the expected therapeutic effect after wearing the corresponding orthosis, but also often leading to the fact that the patient is psychologically unwilling to further cooperate with the treatment due to the discomfort of wearing, which needs to be improved.

DETAILED DESCRIPTION

[0064] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0065] In order to make the drawing simple, only the parts related to the present application are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0066] As is known to all, an orthosis is an external device acting on the limbs or trunk of the human body on the basis of human biomechanics, used to change or compensate the function or structure of the nervous, muscular and skeletal systems, and its main functions include fixation and protection, stability and support, prevention and correction of deformity, compensation of function, local unloading, inhibition of spasm, etc. For example, a wrist-hand orthosis is used to prevent and correct wrist-hand joint disorders. At present, most of the wrist-hand orthosis used in clinical practice is directly covered on the affected limb by a heated low-temperature thermoplastic sheet to shape, and at the same time, the affected limb needs to be kept in a suitable position and wait for the sheet to cool and harden to form.

[0067] At present, the control method is mainly used to shape the wrist-hand orthosis in clinical practice, that is, the maker keeps the affected limb in a suitable position with one hand and shapes the sheet with the other hand. This method depends on the maker's orthosis making skills and experience, the ability to control the affected limb with one hand, the fine handling ability of the orthosis with one hand, and the objective cooperation degree of the patient, etc. However, during the actual operation process, the joints of the affected limb are often difficult to brake due to the reasons such as high muscle tension of the affected limb, too large difference between the hand shapes of the patient and the maker, the patient's inability to fully cooperate with the making, the fast cooling speed of the sheet, etc., so that the orthosis made cannot keep the affected limb in a suitable position, which not only leads to the inability of the affected limb to achieve the expected effect after wearing the wrist-hand orthosis, but also often leads to the decrease of the patient's willingness to use the wrist-hand orthosis due to the discomfort of wearing, and the patient is unwilling to further cooperate with the treatment.

[0068] To this end, with reference to the drawings of the specification Figure 1 In one embodiment, a wrist-hand fixation brace is provided, comprising a body support 1 and a palm support 2 arranged thereon, wherein the palm support 2 is used to support the palm of the patient; a plurality of finger support groups 3 are detachably connected to the palm support 2, and the finger support groups 3 are used to support different fingers of the patient; specifically, any finger support group 3 comprises a plurality of finger supports, and the plurality of finger supports are movably arranged relative to the palm support 2, used to support different segments of the corresponding finger respectively and drive the segments of the corresponding finger to adjust to the preset position and angle; and a fixing structure is arranged on any finger support, and the fixing structure is used to fix the finger of the patient on the corresponding finger support; in addition, a first locking structure 4 corresponding to the finger support is arranged, and the first locking structure 4 is used to fix the finger support after adjusting the position and angle of the corresponding finger support, so that the finger of the patient is passively fixed after being placed on the corresponding finger support.

[0069] In clinical use, the palm support 2 supports the palm of the patient, and keeps each segment of the corresponding finger of the patient supported on each finger support, the patient's fingers are fixed on the corresponding finger support by the fixing structure, the positions and angles of different finger supports of each finger support group 3 are adjusted until the corresponding fingers of the patient are in a suitable body position, for example, in a good limb position, and then the first locking structure 4 is used to keep each finger support fixed, so as to realize the braking of each joint of the patient's fingers and keep them in a suitable body position.

[0070] In this way, by assisting the patient's limb joint braking and temporary fixation with the device, compared with the operation of the commonly used pure manual method of braking and fixing the patient's limb in clinic, it is helpful to reduce the cooperation requirements of the operator and the patient, thereby effectively reducing the difficulty of braking the patient's limb joint; at the same time, since the wrist and hand orthosis is first fixed in a preset body position by using the wrist and hand fixing brace during molding, the operator can use both hands to adjust, brake and fix each joint to a special angle, so that the operation process of the patient's limb joint braking is more clear, controllable, convenient and efficient, and is also conducive to reducing the probability of limb spasm; moreover, since the operator's hands originally used to control the patient's limb are freed, the operator can use both hands to finely shape the plate material during the wrist and hand orthosis manufacturing process, so that the details of the finished wrist and hand orthosis are more suitable for the patient's limb, which is not only conducive to keeping the patient's limb in a suitable body position and facilitating the achievement of the expected treatment effect, but also helps to improve the comfort of the patient wearing the corresponding wrist and hand orthosis and increase the patient's treatment willingness; in addition, the operator can participate in the manufacturing after receiving the related theory teaching of the orthosis, which helps to reduce the training cost of the operator for the posture fixing method and facilitates the faster delivery of the corresponding wrist and hand orthosis.

[0071] In one embodiment, based on the above embodiment, specifically, referring to Figure 1 and Figure 2 , the body support 1 includes a base 11 and a support rod 12, the support rod 12 is vertically fixedly installed on the base 11 and located at the middle part of the base 11, and the palm support 2 is installed at the top end of the support rod 12. Referring to Figure 4 , in order to improve the flexibility of the wrist and hand fixing brace, a sleeve 13 is coaxially sleeved at the top end of the support rod 12, the sleeve rod can rotate relative to the support rod 12 around its own axis; at the same time, the top end of the sleeve rod is formed with a first hinge ear 14; correspondingly, a second hinge ear 21 is detachably installed below the palm support 2, the first hinge ear 14 and the second hinge ear 21 are hinged, and the rotation axis direction is generally consistent with the arrangement direction of the fingers, so that the palm support 2 can rotate in the preset horizontal plane and vertical plane, thereby making the wrist and hand fixing brace meet the requirements of different patients and wrist and hand orthosis manufacturers, and improving its use convenience.

[0072] Of course, for further convenience, in this embodiment of the present application, the palm support 2 is vertically lifted, for example, a power cylinder or a power air cylinder is arranged as the support rod 12, that is, the support rod 12 is arranged as a telescopic rod structure, and a lifting mechanism is arranged between the support rod 12 and the palm support 2 to achieve the corresponding function, so that the wrist and hand fixing support is suitable for patients of different heights and corresponding wrist and hand orthosis manufacturers. The lifting arrangement of the palm support 2 is not repeated, and the specific implementation form of the lifting function should not be regarded as a limitation on the protection scope of the present application.

[0073] With reference to Figures 1 to 3 In this embodiment of the present application, the palm support 2 is adapted to the palm shape of the human body and has a generally rectangular plate structure, and the finger support group 3 is movably arranged at one end of the palm support 2 in the length direction. In this embodiment of the present application, the finger support group 3 is provided with four finger support groups 3, which are arranged at intervals along the finger arrangement direction and are respectively used to support the index finger, the middle finger, the ring finger and the little finger of the patient. Therefore, any finger support group 3 includes three finger supports for supporting three segments of the corresponding finger.

[0074] With reference to Figure 3 Any finger support includes a vertical plate 311 and a support plate 312. Specifically, the vertical plate 311 is arranged at one end of the support plate 312, and the corresponding finger support has an L-shaped structure. After assembly, the vertical plate 311 is arranged vertically, and the support plate 312 is arranged horizontally. The top surface of the support plate 312 is recessed inwardly and forms a positioning groove 3121 for placing the patient's finger. The length directions of the three positioning grooves 3121 of any finger support group 3 are consistent and extend along the length direction of the corresponding finger, so that the corresponding finger of the patient is supported on the corresponding finger support group 3.

[0075] In addition, the middle part of the support plate 312 is provided with a through hole 3122. In this embodiment of the present application, the fixing structure includes a flexible member, such as a strap, a bandage, a magic tape, etc. During clinical use, the flexible member penetrates through the corresponding through hole 3122 and is detachably wound on the corresponding segment of the patient's finger, so that the affected limb is fixed on the corresponding finger support group 3. The fixing structure of the joint of the affected limb is simple, and the clinical use is convenient, which helps to further reduce the difficulty of fixing operation of the joint of the affected limb.

[0076] It is worth noting that the size of the finger support of the present application is relatively small compared with the corresponding finger joint, so it will not affect the accuracy of the molding process during the production of the orthosis.

[0077] With reference to Figures 1 to 3The wrist-hand fixation support further comprises a connecting piece 5 corresponding to each finger support. For the convenience of describing the technical solution of the present application, the three finger supports of any finger support group 3 are sequentially named as a first finger support 31, a second finger support 32 and a third finger support 33, and the finger support close to the palm support 2 is the first finger support 31. The first finger support 31, the second finger support 32 and the third finger support 33 of any finger support group 3 are sequentially connected through the connecting piece 5.

[0078] In this embodiment of the present application, with reference to Figures 1 to 4 The connecting piece 5 comprises a first connecting rod 51 and a second connecting rod 52, and the first connecting rod 51 and the second connecting rod 52 are hingedly connected through a pin 6. The upright plate 311 of the first finger support 31, the second finger support 32 and the third finger support 33 are hingedly connected with the second connecting rod 52 of the corresponding connecting piece 5 through the pin 6, and the rotation axis is consistent with the rotation axis of the corresponding finger segment, and the hinge points are located at the end of the corresponding second connecting rod 52 away from the hinge with the corresponding first connecting rod 51. At the same time, the first connecting rod 51 corresponding to the first finger support 31, the second finger support 32 and the third finger support 33 is hingedly connected with the second connecting rod 52 corresponding to the palm support 2, the second connecting rod 52 corresponding to the first finger support 31, and the second connecting rod 52 corresponding to the second finger support 32 through the pin 6, so as to realize the sequential connection of the first finger support 31, the second finger support 32 and the third finger support 33 in the finger support group 3, and the connection of the first finger support 31 and the palm support 2; the connecting structure is simple, convenient for production and use, further reduces the difficulty of operation of the joint fixation of the affected limb, and helps to save the production cost of the wrist-hand fixation support. Of course, in the embodiment of the present application, similar modular components of different lengths can also be used to replace the first connecting rod 51 and the second connecting rod 52, so as to adjust the spatial activity range of the finger support and expand the spatial activity flexibility of the corresponding finger support, which helps to further enhance the applicability of the wrist-hand fixation support; the specific structure of the replacement parts of the connecting piece 5 is not described here.

[0079] In this embodiment of the present application, the first locking structure 4 comprises a first cam wrench; the first cam wrench is provided at both ends of the second connecting rod 52 corresponding to the first finger support 31, the second finger support 32 and the third finger support 33, and one-to-one correspondence exists between the first cam wrench and the pin 6; during assembly, for the third finger support 33, the pin 6 is sequentially inserted through the third finger support 33, the corresponding second connecting rod 52 and then hinged with the first cam wrench; for the first finger support 31 and the second finger support 32, the pin 6 is sequentially inserted through the corresponding first finger support 31 or the second finger support 32, the second connecting rod 52 and the first connecting rod 51 and then hinged with the first cam wrench; for the connection between the first connecting rod 51 and the second connecting rod 52 of any connecting piece 5, the pin 6 is sequentially inserted through the second connecting rod 52 and the first connecting rod 51 and then hinged with the first cam wrench, and the rotation axes are consistent with the rotation axes of the corresponding segments of the fingers. During clinical use, the handle of the corresponding first cam wrench is rotated until the outer cylindrical surface of the first cam wrench abuts against the first connecting rod 51 and / or the second connecting rod 52, so that the corresponding adjacent first connecting rod 51 and second connecting rod 52 are locked, the corresponding finger support is locked, and the corresponding finger support is kept at a preset angle and position. The characteristics of the first cam wrench are used to lock the state of each finger support, the operation is simple, the convenience of the operation of the joint braking and fixing of the affected limb is effectively improved, and the overall structure has high modularization, which is helpful to further reduce the corresponding production cost investment of the enterprise.

Specifically, any connecting structure 7 comprises a pressing plate 71, a connecting column 72 and an abutting plate 73, which are sequentially fixedly connected; in order to ensure the connection stability of the three and improve the overall structural strength, the pressing plate 71, the connecting column 72 and the abutting plate 73 are integrally formed in this embodiment of the present application, of course, the effective fixation of the three can also be realized through clamping, locking and other structures, which are not enumerated one by one in this embodiment.

[0081] Correspondingly, with reference to Figure 4 and Figure 5 , the arc-shaped hole 22 is arranged on the palm support 2 and extends along the arrangement direction of the fingers; during assembly, the connecting column 72 is embedded in the corresponding arc-shaped hole 22 and slides along the inner wall of the corresponding arc-shaped hole 22 in the length direction of the arc-shaped hole 22, and at the same time, the connecting column 72 can also rotate around the axis relative to the inner wall of the arc-shaped hole 22; the connection relationship between any connecting column 72 and the inner wall of the corresponding arc-shaped hole 22 is a tight fit connection; the pressing plate 71 and the abutting plate 73 abut against the top surface and the bottom surface of the palm support 2, respectively.

[0082] In clinical application, the manufacturer of the wrist-hand orthosis pushes the corresponding connecting column 72 to slide along the length direction of the corresponding arc-shaped hole 22, so as to adjust the distance between the adjacent finger support groups 3, and pushes the first connecting rod 51 of the corresponding first finger support 31 to rotate around the connecting column 72, so as to adjust the left and right swing of the corresponding finger support group 3 around the vertical axis, so that the wrist-hand fixing support is suitable for different hand shapes and sizes of patients.

[0083] Of course, in the embodiments of the present application, one of the connecting columns 72 can also be arranged to rotate only around its own axis relative to the palm support 2, so that the corresponding finger support group 3 serves as a positioning reference to ensure the relative position relationship between the finger support groups 3. Referring to Figure 1 、 Figure 4 and Figure 6 , the case of taking the middle finger corresponding finger support group 3 as the positioning reference is shown, and of course, other embodiments of the present application can also arrange other finger support groups 3 as the positioning reference.

[0084] Referring to Figure 5 and Figure 6 , the connecting structure 7 further includes a connecting lug 74 and a second locking structure 75, wherein the connecting lug 74 is formed on the end of the abutting plate 73 away from the connecting column 72, and the second locking structure 75 includes a second cam wrench; the pin 6 is in turn inserted through the first connecting rod 51 of the first finger support 31 and the connecting lug 74 and then hinged with the second cam wrench, and the rotation axis is consistent with the rotation axis of the corresponding segment of the finger, so as to realize the hinge connection between the first connecting rod 51 of the first finger support 31 and the palm support 2. In clinical application, when the handle of the second cam wrench is pulled to the outer circular surface of the second cam wrench to tightly abut against the connecting lug 74, the first connecting rod 51 of the first finger support 31 can be locked relative to the palm support 2. The locking structure is simple and easy to operate.

[0085] Further, in this embodiment of the present application, the side of the palm support 2 close to the patient's thumb, i.e. one side of the palm support 2 in the width direction, is provided with an extension plate 23, the extension plate 23 is integrally formed with the palm support 2 and extends away from the palm support 2 along the arrangement direction of the fingers; an inner arc edge 24 is formed between the extension plate 23 and the palm support 2; in order to expand the adjustment range of the distance between the adjacent finger support groups 3, the arc-shaped hole 22 can be arranged on the extension plate 23.

[0086] It is known that the area of the palmar crease to the fourth finger moves with the fourth finger, and the area within the thenar curve to the thumb moves with the thumb; therefore, in clinical application, the palmar crease of the affected limb should be placed outside the palm support 2, that is, the position of the palmar crease to the fourth finger of the affected limb is not placed on the palm support 2; and the end of the affected limb near the thumb should be tangent to one side of the inner arc edge 24 connected to the extension plate 23 as much as possible, and the thenar curve should protrude the inner arc edge 24, that is, the area within the thenar curve to the thumb of the affected limb is not placed on the palm support 2; in this way, after the palm of the affected limb is supported on the palm support 2, each finger can rotate normally relative to the palm without being blocked by the palm support 2, and the corresponding finger joints will not push the palm support 2 to move relative to the palm, thereby effectively ensuring the normal progress of the wrist-hand orthosis manufacturing process and the stability of the palm supported on the palm support 2.

[0087] In addition, in this embodiment of the present application, the palm support 2 can support the palm side of the right hand and the back side of the left hand; during clinical use, by using a palm support structure that is a mirror image of the palm support 2 of the present application, the left palm side and the right back side can be supported.

[0088] The implementation principle of the embodiment of the present application is that: by assisting the joint of the affected limb to brake and temporarily fix with the instrument, compared with the operation of braking and fixing the affected limb by pure manual method commonly used in clinical practice, it is helpful to reduce the cooperation requirement between the manufacturer and the patient, thereby effectively reducing the difficulty of braking the joint of the affected limb; at the same time, since the wrist-hand orthosis is formed by first fixing the affected limb in a preset body position using the wrist-hand fixing brace, the manufacturer can use both hands to adjust, brake and fix each joint to a special angle, so that the operation process of braking the joint of the affected limb is more clear, controllable, convenient and efficient, and is also conducive to reducing the probability of spasm of the affected limb; moreover, since the hands of the manufacturer are freed from controlling the affected limb, the manufacturer can use both hands to finely shape the plate material during the manufacturing process of the wrist-hand orthosis, so that the details of the finished wrist-hand orthosis are more suitable for the patient's limb, which is not only conducive to keeping the affected limb in a suitable body position to facilitate achieving the expected treatment effect, but also helps to improve the comfort of the patient wearing the corresponding wrist-hand orthosis and increase the patient's treatment willingness; in addition, the manufacturer can participate in the manufacturing after receiving the related theory teaching of the orthosis, which helps to reduce the training cost of the manufacturer for the posture fixing method, and is conducive to faster delivery of the corresponding wrist-hand orthosis. In addition, the overall structure is simple, the production and manufacturing are convenient, the production cost investment of the enterprise for the wrist-hand fixing brace is effectively reduced, and energy saving and cost reduction are facilitated.

[0089] It should be noted that the above embodiments can be freely combined as needed. The above description is only the preferred embodiments of the present application, and it should be noted that for ordinary skilled persons in the technical field, several improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
