Description

Finger joint fixing device

Technical Field

The utility model is suitable for a medical instrument technical field, more specifically relates to a finger joint fixing device.

Background

Tenosynovitis is one of the most common diseases of the hands and occurs in high proportion in the human population. For early tenosynovitis patients, the finger is often braked to reduce friction between the tendon and the sheath pulley, thereby improving the symptoms of tenosynovitis. Good brace fixation is critical for the treatment of early stage patients. However, most of the traditional tenosynovitis fixing braces are hard fixing devices positioned on the palm side, so that the patient cannot perform daily simple actions after wearing the brace, the brace is poor in long-term wearing comfort, and the daily work and life are obviously affected, so that most of the patients abandon the brace for fixing and select a medicine, physical therapy or local closed treatment mode. How to restrict the movement of the affected finger and interfere with daily activities as little as possible is a key joint for the design of tenosynovitis braces.

In the finger movement, the movement range of the metacarpophalangeal joint and the proximal interphalangeal joint is large, and the movement of the two joints is closely related to the sliding range of the tendons. Therefore, if the metacarpophalangeal joint and the proximal interphalangeal joint can be fixed in the functional position, the functional requirements of the affected finger can be met, and the purpose of limiting the range of motion of the affected finger can be met. In addition, when the brace is placed on the back side of the hand, the finger pulp can still be contacted with an object, and the function of the affected finger, such as grasping the object and knocking the keyboard, can be performed.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a finger joint fixing device to solve the technical problem of the daily activity of the restriction patient hand that exists in the current protective equipment.

In order to achieve the above object, the present invention provides the following specific technical solutions: the utility model provides a finger joint fixing device, is including the fixed plate that is used for fixed finger joint, still includes the elastic fixation area who closely laminates with the palm, the fixed plate set up in elastic fixation area's dorsal part, convenient to use person's hand gripping.

Preferably, the fixed plate is T-shaped, and including back of the hand and finger portion, back of the hand area is greater than finger portion area, can make the fixed plate more stable.

Preferably, an included angle between the plane where the back of the hand and the plane where the finger part is located is an obtuse angle.

Preferably, the finger portion is arc-shaped.

Preferably, the finger portion is curved toward the palm side; the back of the hand with the contained angle of finger portion to and the radian of finger portion for metacarpophalangeal joint and near side interphalangeal joint all are located the functional position, are convenient for the hand normal gripping and use daily life work such as keyboard.

Preferably, the fixing plate is provided with a plurality of through holes, so that the fixing plate is more breathable and comfortable when being worn by a user.

Preferably, the part of the elastic fixing band connected with the finger part is provided with a finger sleeve.

Preferably, the finger sleeves are communicated front and back, so that finger abdomens are exposed, and the use of a touch screen and a keyboard is facilitated.

Preferably, the fixing plate is made of a low-temperature thermoplastic material, which is lightweight and adjustable.

Compared with the prior art, the utility model discloses the beneficial effect who reaches:

1) the main fixing material is a low-temperature thermoplastic plate, is placed on the back sides of fingers and the palm, is light and adjustable, and is convenient for hand grasping in a back side mode.

2) The metacarpophalangeal joints and the proximal interphalangeal joints are located at functional positions, so that the hands can normally grasp and use the keyboard and the like for daily life and work.

3) The finger abdomen is exposed, which is convenient for the use of touch screen and keyboard.

4) The distal interphalangeal joints are not fixed, so that the integral braking of the tendons of the fingers is not obstructed, and the functions of the fingers can be exerted as much as possible.

5) The elastic fixing band is simple and firm in fixing mode and convenient to wear in life and work.

Detailed Description

As used in the specification and in the claims, certain terms are used to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.

Referring to fig. 1-2, a finger joint fixing device 200 includes a fixing plate 220 for fixing a finger joint, and further includes an elastic fixing band 210 tightly attached to a palm, wherein the fixing plate 220 is disposed on a back side of the elastic fixing band 210, so as to facilitate grasping of a hand of a user.

Further, the fixing plate 220 is T-shaped, and includes a back of the hand and fingers, the length of which is approximately equal to the length of the adult from the distal interphalangeal joint to the wrist joint level, and the area of the back of the hand is larger than the area of the fingers, which not only does not obstruct the wrist joint movement, but also makes the fixing plate more stable.

Furthermore, an included angle between the plane where the back of the hand is located and the plane where the finger is located is an obtuse angle, preferably between 120 degrees and 170 degrees, and more preferably 150 degrees; the finger parts are arc-shaped according to the trend of finger joints, specifically, the finger parts are bent towards the palm side, specifically, the radian can be selected from 0.35-0.87, preferably 0.7, which is equivalent to 40 degrees; the back of the hand with the contained angle of finger portion to and the radian of finger portion for metacarpophalangeal joint and near side interphalangeal joint all are located the functional position, are convenient for the hand normal gripping and use daily life work such as keyboard.

Further, a plurality of through holes are formed in the fixing plate 220, so that the fixing plate is more breathable and comfortable when being worn by a user.
