DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0030] As shown in FIG. 1, an orthosis device having a metal wire adjusting structure according to a first embodiment of the present invention comprises a palm orthosis body 1 and a forearm orthosis body 2.

[0031] One end of the palm orthosis body 1 is provided with a first coupling portion 11. The other end of the palm orthosis body 1 is provided with a plurality of fixing portions 12. As shown in FIG. 2, a plurality of adjustment seats 13 are connected to the fixing portions 12 by screws 121, respectively. The adjustment seats 13 each have a first through hole 131 for insertion of a first end 141 of an elastic metal wire 14. A first adjusting bolt 15 is vertically screwed to the outer side of each of the adjustment seats 13, so as to tighten and secure the first end 141 of the elastic metal wire 14. The elastic metal wire 14 is made of iron or steel, and its diameter is between 0.8 mm and 2.0 mm. An elastic metal wire 14 with an appropriate diameter is selected and installed according to the requirement of a different elastic restoring force. A second end 142 of the elastic metal wire 14 is inserted into a second through hole 161 of a movable seat 16, as shown in FIG. 3. A second adjusting bolt 17 is vertically screwed to the outer side of the movable seat 16, so as to tighten and secure the second end 142 of the elastic metal wire 14. In addition, a finger sleeve 18 is connected to the movable seat 16 for a corresponding one of a user's fingers to be inserted and positioned in the finger sleeve 18.

[0032] The forearm orthosis body 2 is provided with a second coupling portion 21. The second coupling portion 21 is coupled to the first coupling portion 11 through a connecting rod 22, so that the palm orthosis body 1 is coupled to the forearm orthosis body 2. Two sides of the forearm orthosis body 2 are provided with fastening straps 23. The fastening straps 23 are secured with a hook-and-loop tape 231.

[0033] When in use, as shown in FIG. 1 and FIG. 4, the forearm orthosis body 2 is fitted onto a user's forearm A close to the wrist, and the fastening straps 23 on both sides of the forearm orthosis body 2 are wound around the forearm A and secured with the hook-and-loop tape 231, so that the forearm A is positioned in the forearm orthosis body 2. Then, the user's fingers A1 are inserted and positioned in the finger sleeves 18 of the movable seats 16, respectively. The elastic restoring force of the elastic metal wire 14 provides a backward pulling force to the corresponding finger A1 through the second end 142, so as to perform rehabilitation on the finger to prevent the finger A1 from curling and deforming.

[0034] As shown in FIG. 4 and FIG. 5, according to the different degree of rehabilitation of the finger A1, when it is necessary to select a larger or smaller elastic restoring force, the first adjusting bolt 15 on the adjustment seat 13 corresponding to the position of the finger A1 is loosened and the second adjusting bolt 17 on the movable seat 16 corresponding to the position of the finger A1 is loosened, so that the first end 141 and the second end 142 of the elastic metal wire 14 are released, respectively. Then, the elastic metal wire 14 is removed from the adjustment seat 13 and the movable seat 16, and another elastic metal wire 14A with a different diameter is selected according to the degree of rehabilitation of the finger A1. The first end 141A of the elastic metal wire 14A is inserted into the first through hole 131 of the adjustment seat 13, and then the first adjusting bolt 15 is tightened, so as to tightly secure the first end 141A of the elastic metal wire 14A. After that, the second end 142A of the elastic metal wire 14A is inserted into the second through hole 161 of the movable seat 16, and then the second adjusting bolt 17 is tightened, so as to tightly secure the second end 142A of the elastic metal wire 14A. In this way, the elastic metal wire 14A with a different diameter can be easily and quickly replaced for rehabilitation. In the embodiment of the present invention, the elastic metal wire 14A with a smaller diameter is selected for exerting a smaller elastic restoring force to the finger A1, in cooperation with the degree of rehabilitation of the finger A1.

[0035] Thus, according to the different angle of curling of the finger A1, an elastic metal wire 14A with a different diameter can be replaced, so that a different elastic restoring force is generated to cooperate with a different finger A1 for rehabilitation. By screwing or unscrewing the first adjusting bolt 15 on the adjustment seat 13 and the second adjusting bolt 17 on the movable seat 16, the elastic metal wire 14 with a different diameter can be replaced easily and quickly for rehabilitation.

[0036] FIG. 6 illustrates a second embodiment. The second embodiment is substantially similar to the first embodiment with the exceptions described hereinafter.

[0037] A plurality of adjustment seats 33 are connected to the palm orthosis body 3. Each adjustment seat 33 is formed with a first locking groove 331. A first locking block 332 is detachably engaged in the first locking groove 331. A first end 341 of an elastic metal wire 34 is inserted and secured to the first locking block 332. A movable seat 36 is formed with a second locking groove 361. A second locking block 362 is detachably engaged in the second locking groove 361. A second end 342 of the elastic metal wire 34 is inserted and secured to the second locking block 362. When the first locking block 332 is separated from the first locking groove 331 and the second locking block 362 is separated from the second locking groove 361, the elastic metal wire 34 of a different diameter can be optionally replaced.

[0038] FIG. 7 illustrates a third embodiment. The third embodiment is substantially similar to the first embodiment with the exceptions described hereinafter.

[0039] A plurality of adjustment seats 43 are connected to the palm orthosis body 4. The adjustment seat 43 is provided with a first elastic portion 431 that is tapered and has a cut-out area. A first nut 432 is screwed to the first elastic portion 431. A first end 441 of an elastic metal wire 44 is inserted into the first elastic portion 431, and then the first nut 432 is tightened, so as to tightly secure the first end 441 of the elastic metal wire 44. A movable seat 46 is provided with a second elastic portion 461. A second nut 462 is screwed to the second elastic portion 461. A second end 442 of the elastic metal wire 44 is inserted into the second elastic portion 461, and then the second nut 462 is tightened, so as to tightly secure the second end 442 of the elastic metal wire 44. By unscrewing the first nut 432 and the second nut 462, the elastic metal wire 44 with a different diameter can be optionally replaced.

[0040] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
