A preferred embodiment of the present invention is an arthritic appliance.

In this embodiment, the arthritis correction fixture is used to be disposed in a finger of a patient with arthritis and connect a distal phalanx and a middle phalanx of the finger, but not limited thereto.

Referring to fig. 1 to 6, fig. 1 to 5 are exploded views of the components of the arthritis correction fixing device 6; fig. 6 is a schematic view of the arthritis correction fixture 6. Wherein, fig. 1 is an exploded view of a screw 10, a fixing portion 11 and a connecting seat 12; fig. 2A and 2B are a schematic view and a cross-sectional view of the screw 10 engaged with the connecting seat 12 through the fixing portion 11, respectively; fig. 3 is an exploded view of the first coupling part 1 and the first screw part 2; fig. 4 is a schematic view of the first screw portion 2 being sleeved on the screw 10 of the first connection portion 1 to form the first unit 3; fig. 5 is an exploded view of the first unit 3 and the second unit 4 connected by the connection unit 5.

First, as can be seen from fig. 6: the arthritis-correcting fixture 6 may include a first unit 3, a second unit 4, and a connecting unit 5, and the first unit 3 and the second unit 4 are connected to each other by the connecting unit 5 so that the first unit 3 and the second unit 4 can move relative to each other. The first unit 3 may include a first connection portion 1 and a first screw portion 2, and the first screw portion 2 has a screw 20.

Next, as can be seen from fig. 1 to 4: the first connecting portion 1 of the first unit 3 may include a screw 10, a fixing portion 11 and a connecting seat 12. The screw 10 may include a threaded portion 100 and a bottom portion 102, and the threaded portion 100 and the bottom portion 102 are connected to each other. The connecting socket 12 may include a first through hole 120, a groove 122 and a receiving space SP. The groove 122 is disposed above the connecting socket 12 for accommodating the fixing portion 11 and the bottom portion 102 of the screw 10, so that the bottom portion 102 of the screw 10 is engaged with the groove 122 of the connecting socket 12 through the fixing portion 11. The accommodating space SP is located below the connecting seat 12, and the first through hole 120 is disposed corresponding to the accommodating space SP.

After the screw 10 is engaged with the connecting seat 12 through the fixing portion 11, the first screw portion 2 is sleeved on the screw 10 of the first connecting portion 1 to form the first unit 3, as shown in fig. 3 and 4. The screw 10 is disposed in the first threaded portion 2 and engaged with the first connecting portion 12, and the threaded portion 100 of the screw 10 and the first threaded portion 2 rotate in opposite directions, for example, clockwise and counterclockwise, respectively, but not limited thereto.

As shown in fig. 5, the second unit 4 may have a second screw portion 40 and a second connection portion 42, and the second screw portion 40 and the second connection portion 42 are connected to each other or integrally formed. The second connection portion 42 has a second through hole 420. When the second connection portion 42 is received in the receiving space SP of the first connection portion 1, the first through hole 120 of the first connection portion 1 and the second through hole 420 of the second connection portion 42 may be aligned with each other, and the connection unit 5 simultaneously passes through the first through hole 120 and the second through hole 420 to connect the first connection portion 12 and the second connection portion 42, so that the first unit 3 and the second unit 4 may move relative to each other, but not limited thereto.

In fact, the connection unit 5 may be a pivot shaft, such that the first unit 3 and the second unit 4 connected to each other by the connection unit 5 can move relative to each other with the connection unit 5 as an axis and have a specific included angle, but not limited thereto.

Next, referring to fig. 7 and 8, fig. 7 and 8 are schematic diagrams illustrating the distal phalanx FB1 and the middle phalanx FB2 being spread apart by the arthritis correction fixing device 6 disposed between the distal phalanx FB1 and the middle phalanx FB 2.

As shown in fig. 7 and 8, the first threaded part 2 of the first unit 3 is connected to the distal phalanx FB1 and the middle unit 4 is connected to the middle phalanx FB 2. When the first thread part 2 of the first unit 3 rotates in the first rotation direction (e.g. clockwise direction) SC1, since the rotation direction of the thread part 100 of the screw 10 located in the first thread part 2 is opposite to the rotation direction of the first thread part 2, that is, the thread part 100 of the screw 10 rotates in the second rotation direction (e.g. counterclockwise direction) SC2 to move away from the first thread part 2, and the first connection part 1 and the second unit 4 connected to the first connection part 1, which bring the middle phalanx FB2 away from the distal phalanx FB1, so that the distance between the distal phalanx FB1 and the middle phalanx FB2 increases to reduce the possibility of friction between them, the phenomenon that the distal phalanx 1 and the middle phalanx FB2 rub against each other can be effectively improved, so as to relieve the pain caused by arthritis.

In addition, as shown in fig. 9, the present invention can also further assist the adjustment of the distance between the distal phalanx FB1 and the middle phalanx FB2 by the aid of the auxiliary device 9. For example, the auxiliary device 9 may include a substrate P, an auxiliary unit N1 and a control unit N2, and the auxiliary unit N1 and the control unit N2 are disposed on the substrate P. When the distal phalanx FB1 and the middle phalanx FB2 are disposed in the space formed by the plurality of first auxiliary units N1 on the substrate P, the control unit N2 may be disposed above the connection point (i.e., the finger joint) between the distal phalanx FB1 and the middle phalanx FB2, for controlling the operation of the arthritis correction fixing device disposed between the distal phalanx FB1 and the middle phalanx FB2, but not limited thereto. Fig. 10A and 10B illustrate a side view and a top view of fig. 9, respectively.

Another preferred embodiment of the present invention is a method of operating an arthritic appliance.

In this embodiment, the arthritis correction fixture operating method is used to operate the arthritis correction fixture disposed in the finger of the finger arthritis patient and connect the distal phalanx and the middle phalanx of the finger.

The arthritis correction fixing device comprises a first unit, a second unit and a connecting unit. The first unit is provided with a first thread part and a first connecting part. The second unit is provided with a second thread part and a second connecting part.

Referring to fig. 11, fig. 11 is a flowchart illustrating an operation method of the arthritis correction fixing device in this embodiment.

As shown in FIG. 11, the method of operating the arthritic fixation device may include the following steps:

step 1010: the first connecting part and the second connecting part are connected through the connecting unit, so that the first unit and the second unit can move relative to each other;

step 1030: connecting the first unit and the second unit with the far end phalanx and the middle end phalanx respectively;

step 1050: when the first thread part rotates, the first connecting part drives the second unit to move together in a direction away from the first thread part so as to change the distance between the far-end phalange and the middle-end phalange.

In practical applications, the first unit may further include a screw disposed in the first threaded portion and engaged with the first connecting portion, and the rotation directions of the screw and the first threaded portion are opposite to each other. When the first thread part rotates in a first rotating direction (for example, clockwise), the screw rotates in a second rotating direction (for example, anticlockwise) opposite to the first rotating direction and moves towards a direction far away from the first thread part, and drives the first connecting part clamped with the screw and the second unit connected with the first connecting part to move towards a direction far away from the first thread part, so that the distance between the far-end phalange and the middle-end phalange is increased by adopting a Joint distraction (Joint distraction) method, the far-end phalange and the middle-end phalange cannot rub against each other, and pain caused by finger arthritis can be effectively relieved.

In practical applications, the first connecting portion and the second connecting portion may have a first through hole and a second through hole, respectively. The first connecting portion may have an accommodating space for accommodating the second connecting portion. When the second connection portion is accommodated in the accommodating space of the first connection portion, the first through hole of the first connection portion and the second through hole of the second connection portion may be aligned with each other, and the connection unit passes through the first through hole and the second through hole to connect the first connection portion and the second connection portion, so that the first unit and the second unit may move relative to each other, but not limited thereto.

Compared with the background art, when the fingers of the patient suffer from arthritis, the arthritis correction fixing device and the operation method thereof can be arranged in the fingers of the patient and connected between the far-end phalanx and the middle-end phalanx, and the distance between the far-end phalanx and the middle-end phalanx can be adjusted by adopting a Joint distraction (Joint distraction) method according to the actual requirements of the patient, so that the far-end phalanx and the middle-end phalanx can be relatively distracted, the far-end phalanx and the middle-end phalanx can be prevented from rubbing against each other, and the pain feeling generated when the fingers of the patient are actuated can be effectively relieved.

The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the claims.
