Embodiment 1

[0027] Such as figure 1 , figure 2 As shown, a damping type wrist joint fixation device includes a finger connecting portion 1, a forearm connecting plate 2, a guide rod 3 and four damping rubber rings 4;

[0028] Such as image 3 As shown, the finger connecting part 1 includes a finger connecting plate 11 and a connecting rod 12, the front end of the connecting rod 12 is vertically connected with the middle part of the top of the finger connecting plate 11, and the finger connecting plate 11 is provided with three fingers. hole 111;

[0029] Such as figure 1 , figure 2 As shown, the forearm connecting plate 2 is provided with three ear plates 21 arranged parallel to each other, the ear plates 21 are provided with mounting holes, and the ear plates 21 and the forearm connecting plate 2 are vertically connected to each other;

[0030] Such as Figure 4 As shown, the surface of the guide rod 3 is smooth, the front end is provided with a connecting ear 31, and the connect...

Embodiment 2

[0036] On the basis of the example, such as figure 1 , figure 2 As shown, two damping rubber rings 4 are sheathed on the guide rod 3 near the connecting ear 31 , and there is a gap between the two damping rubber rings near the connecting ear 31 and the ear plate 21 . The damping wrist joint fixation device in Embodiment 1 has little effect on the range of motion of the patient's wrist joint, but it cannot be used for patients with severe wrist joints, so the scope of application is small. In this embodiment, two damping rubber rings 4 can be added to limit the range of motion of the wrist joint. The principle is as follows: when the finger joint 1 swings with the patient's palm, the guide rod 3 is pushed to move axially , when the damping rubber ring 4 arranged close to the connecting ear 31 touches the front side of the ear plate 21, the finger joint 1 reaches the maximum swing range, which can limit the range of motion of the palm from the surface. By adding the damping ru...

Abstract

The invention discloses a damping type fixing device for wrist joints. The device comprises a finger connecting part, a forearm connecting plate, a guide bar and four damping rubber rings, wherein the finger connecting part comprises a finger connecting plate and a connecting bar, the front end of the connecting bar is vertically connected with the middle of the top end of the finger connecting plate, and three finger holes are formed in the finger connecting plate; three lug plates arranged in parallel are arranged on the forearm connecting plate, a mounting hole is formed in each lug plate, and the lug plates are vertically connected with the forearm connecting plate; the guide bar has a smooth surface and is provided with a connecting lug at the front end. The damping type fixing device for the wrist joints has the advantages that the moving range of the wrist joints is not limited, but the moving speed is better limited, and the fixing device is suitable for being used by a patient at the rehabilitation later stage of the wrist joints and is good for recovery of the wrist joints at the rehabilitation later stage.

Description

technical field [0001] The invention relates to an orthopedic medical device, more precisely a damping wrist joint fixation device. Background technique [0002] In the later stage of wrist joint rehabilitation, restricting the range of motion of the wrist joint is not conducive to the recovery of the wrist joint. On the contrary, moving the wrist joint at a slow speed is more conducive to the recovery of the wrist joint and the recovery of the strength of the wrist joint. However, the wrist joint fixation devices in the prior art are all designed to limit the range of motion of the wrist joint, which is not conducive to the recovery of the wrist joint in the later stage. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, so as to provide a wrist joint that does not limit the range of motion and has a good limit on the speed of motion, which is suitable for patients in the later stage of wrist joint reha...
