Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic postoperative rehabilitation assistance devices, and particularly relates to a rehabilitation training device for the wrist joint after operation. Background Art

[0002] At present, patients with distal radius fractures in orthopaedics are extremely common, accounting for about 1 / 10 of usual fractures, and mostly occur in elderly women, children and young people. Usually, the fracture occurs when a person falls and the palm side of the wrist touches the ground and stretches forward. This type of fracture is mostly an unstable fracture, and most of them require surgical treatment. After the operation on the wrist, the wrist joint needs to be fixed for 4-6 weeks to prevent secondary injury. During the fixation period, due to the limitation of the fixation device and the lack of professional rehabilitation guidance, the wrist joint and finger joints of the patient often have varying degrees of adhesion. The limited movement of the wrist and fingers not only affects the patient's daily activities such as dressing and eating, but also makes the patient unable to normally participate in work for a long time, seriously affecting the patient's quality of life.

[0003] Generally, through correct guidance and functional training during the hospital stay, the functions of the fingers and wrist can be basically maintained. However, after discharge, due to the fixation of the conventional wrist brace or the pain caused by self-training, the patient cannot normally complete the daily fixed-quantity training, so the situation of joint adhesion still cannot be avoided. The Chinese utility model patent with the authorization announcement number CN218076235U discloses a finger joint rehabilitation training glove, which can use an elastic resistance mechanism and a nylon connecting rope to train the finger muscles. However, the elastic resistance mechanism is arranged on the resistance providing seat, and the structures of the resistance providing seat and the elastic resistance mechanism are complex and the cost is high. Moreover, this finger joint rehabilitation training glove cannot adjust the wrist angle, which is not conducive to the recovery of the wrist joint. In addition, the air permeability of this finger joint rehabilitation training glove is poor. Summary of the Utility Model

Detailed implementation manners

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] As Figure 1 shown, this embodiment provides a wrist joint postoperative rehabilitation training device, including a forearm plate 1, a dorsal hand plate 2, and a finger sleeve 6. The forearm plate 1 and the dorsal hand plate 2 are both arc-shaped plate structures, which are respectively used to be fixed on the forearms and dorsal hands of patients. The forearm plate 1 and the dorsal hand plate 2 are both made of hard plastic. Adjustable straps 3 are arranged on both the forearm plate 1 and the dorsal hand plate 2. Among them, two adjustable straps 3 are arranged on the forearm plate 1, and one adjustable strap 3 is arranged on the dorsal hand plate 2. The adjustable strap 3 on the dorsal hand plate 2 is arranged close to the end of the dorsal hand plate 2. The adjustable strap 3 is used to fix the forearm plate 1 and the dorsal hand plate 2 on the forearms and dorsal hands of patients respectively. In this embodiment, the adjustable strap 3 uses Velcro, which is convenient for adapting to forearms and palms of different sizes.

[0033] In order to improve the breathability and comfort of the forearm plate 1 and the dorsal hand plate 2, as Figure 4 shown, a plurality of second ventilation holes 15 are opened on the forearm plate 1 and the dorsal hand plate 2. As Figure 1 shown, a breathable cushion layer 14 is arranged on the inner sides of the forearm plate 1 and the dorsal hand plate 2. The breathable cushion layer 14 enables patients not to directly contact the hard forearm plate 1 and dorsal hand plate 2, and can further improve the comfort of patients while ensuring breathability.

[0034] An adjustment and fixation mechanism is provided between the forearm plate 1 and the dorsal hand plate 2. The adjustment and fixation mechanism is used to adjust the angle between the forearm plate 1 and the dorsal hand plate 2 and fix the angle between the forearm plate 1 and the dorsal hand plate 2. In this embodiment, the adjustment and fixation mechanism includes a sleeve 7, a rotating shaft 13, and an adjusting member 8. The sleeve 7 is fixedly arranged at one end of the forearm plate 1. A long strip-shaped opening 9 is formed on the side wall of the sleeve 7. The length direction of the long strip-shaped opening 9 is parallel to the axial direction of the sleeve 7. The rotating shaft 13 is rotatably arranged in the sleeve 7. One end of the dorsal hand plate 2 passes through the long strip-shaped opening 9 and is integrally connected with the rotating shaft 13. A limiting plate 10 is fixedly arranged at a position near one end in the sleeve 7. The adjusting member 8 includes a threaded portion 11 and a handle portion 12. The threaded portion 11 is inserted into the sleeve 7 and is threadedly connected to the other end of the sleeve 7. By rotating the threaded portion 11 through the handle portion 12, the threaded portion 11 presses the rotating shaft 13 against the limiting plate 10, thereby realizing the fixation of the rotating shaft 13. Through the sleeve 7 and the rotating shaft 13, the forearm plate 1 and the dorsal hand plate 2 can rotate relative to each other. By the adjusting member 8, the rotating shaft 13 can be fixed or loosened, so that the forearm plate 1 and the dorsal hand plate 2 can be fixed at any angle. In this embodiment, the threaded portion 11 is a cylindrical rod with an external thread, and the handle portion 12 is in a V shape and is fixed at one end of the threaded portion 11 extending out of the sleeve 7, which is convenient for rotating the threaded portion.

[0035] In addition, the end face of the threaded portion 11 and the surface of the limiting plate 10 can also be roughened to increase the friction between the rotating shaft 13 and the threaded portion 11 and the limiting plate 10, and ensure the fixing effect of the angle between the forearm plate 1 and the dorsal hand plate 2.

[0036] As Figure 2 shown, five first elastic members 4 are fixedly arranged at one end of the dorsal hand plate 2 away from the forearm plate 1. Finger sleeves 6 are fixedly arranged on the first elastic members 4. Through the first elastic members 4, flexion training of the fingers can be realized. In this embodiment, the first elastic members 4 are elastic silica gel strips.

[0037] In order to improve the comfort and breathability of the finger sleeves 6, the finger sleeves 6 adopt a fabric structure, for example, they are sewn with cotton threads. This not only ensures the breathability of the finger sleeves 6, but also the cotton thread material is soft and the cost is low. The first elastic members 4 and the finger sleeves 6 can also be connected by cotton thread stitching, which is convenient for connection.

[0038] In order to realize adduction and abduction training of the fingers, adjacent two finger sleeves 6 are connected by a second elastic member 5. In this embodiment, the second elastic member 5 adopts an elastic band, which provides a moderate resistance when the patient performs adduction and abduction training.

[0039] The usage method of the wrist joint postoperative rehabilitation training device is as follows: Put the affected hand into the finger sleeve 6, and then use three adjustable straps 3 to fix the distal end of the patient's forearm and the palm. After turning the wrist to the required angle, rotate the handle part 12 to tighten the threaded part 11 into the sleeve 7. The threaded part 11 gradually presses against the rotating shaft 13, so that both ends of the rotating shaft 13 are pressed against the limiting plate 10 and the threaded part 11 respectively, thereby fixing the included angle between the forearm plate 1 and the back of the hand plate 2.

[0040] The first elastic member 4 can provide a certain resistance for the patient's finger grasping, and the second elastic member 5 provides resistance for finger abduction. This device can not only fix the affected wrist joint to avoid secondary injury, but also complete the functional position placement of the wrist joint. Moreover, it can help the patient train the flexion and extension angles of the wrist joint at different times. In addition, the finger part can train the grasping and abduction strength, helping the patient better recover the hand function and enabling the patient to resume function as soon as possible and return to the family and society.

[0041] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the protection scope of the present application.
