Description

Technical Field

[0001] The utility model relates to the technical field of fixing braces, in particular to a fixing brace for a thumb. Background Art

[0002] A fixation brace is a support device placed outside the body to limit certain body movements to assist surgical treatment, or directly used for external fixation in non-surgical treatment. For example, during the radiotherapy process for various diseases, a fixation brace is needed to fix the body position to reduce unnecessary damage to normal tissues caused by body movement during radiotherapy, thereby improving the effect of radiotherapy; during the treatment and rehabilitation period after a fracture of a human body part, a fixation brace is also needed for external fixation to assist in the recovery of the fracture site.

[0003] The fixed brace in the field of radiotherapy can also be called a radiotherapy positioning membrane, which is generally made of a low-temperature thermoplastic plate with plasticity. When in use, it is placed in hot water for heating and softening, and then its shape can be adjusted to fit the corresponding part of the human body. Then, it will harden and become plastic after being left at room temperature for a few minutes, thus forming a fixation effect. For example, the Chinese patent with the announcement number CN208243930U provides a radiotherapy positioning membrane, including a positioning membrane formed by a low-temperature thermoplastic plate membrane. In recent years, fixed braces made of low-temperature thermoplastic plates have also been gradually applied to fracture treatment and rehabilitation. For example, the Chinese patent with the announcement number CN215875140U provides an external fixed brace for rehabilitation after fractures, which includes a low-temperature thermoplastic plate, which can solve the problems of heavy weight, poor air permeability and opacity to X-rays in traditional plaster fixation methods, and help improve the rehabilitation effect.

[0004] The thumb (especially the big thumb) is a hand part that is frequently used in daily life. It is easy to fracture under the action of external force, and it is easy to have lesions such as joint pain. However, traditional fixing clamps are mostly in the form of flat diaphragms (such as the patent CN208243930U cited above), and it is necessary to use its thermoplasticity to plasticize the treatment part before use. However, since there is no support of any basic shape, and the shape of the thumb is relatively three-dimensional and complex, it is easy to have inadequate shaping or even failure, which will affect the fixing effect. In the current market, even though different fixing clamps that are adapted to the main areas of the human body such as the head, neck and shoulders, chest, legs, and hands (such as the patent CN215875140U cited above) have gradually appeared, there is no special fixing clamp for the specific part of the thumb. If a fixing clamp that can fix the hand and arm as a whole is used, it is likely that the fixation will not be in place, and it will also cause unnecessary movement restrictions, thereby adversely affecting the fixing effect and convenience of life. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing brace for the thumb, so as to solve the problem mentioned in the above background technology that there is a lack of a fixing clamp dedicated to the thumb in the prior art.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A thumb fixation brace comprises a positioning film made of a low-temperature thermoplastic plate and a fixed frame, wherein the fixed frame is arranged around the outer edge of the positioning film, a plurality of mesh holes are provided on the positioning film, and the positioning film comprises a thumb area, a thenar area and a wrist area which are integrally connected and formed, and the shapes and sizes of the thumb area, thenar area and the wrist area are respectively adapted to the shapes and sizes of the thumb area, thenar area and the wrist area of ​​the human body.

[0008] In the fixing fixture provided by the utility model, by setting a thumb area adapted to the thumb of the human body, a thenar area adapted to the thenar area of ​​the human body, and a wrist area adapted to the wrist of the human body, the fixing fixture can be worn on the user's hand, and the thumb area of ​​the fixing fixture can limit and fix the thumb of the user. When using the fixing fixture, since the positioning film has a basic shape (i.e., the thumb area, thenar area, and the wrist area), after heating to soften the positioning film, the fixing fixture can be directly fitted on the user's hand, and then fine adjustments can be made based on the existing shape to make the fixing fixture more suitable for the user, and finally wait for hardening and plasticity.

[0009] Furthermore, the thumb area is divided into two types, namely the thumb area and the little finger area, and the thenar area is correspondingly divided into two types, namely the thenar area and the hypothenar area.

[0010] The fixing clamp provided by the utility model has an integrally connected thumb area, thenar area and wrist area. Since the overall structures around the thumb and the little finger are relatively consistent, with the thumb area connected to the thenar area below and the thenar area connected to the wrist area below, the fixing clamp can be used for limiting the fixation of the thumb or the little finger area.

[0011] Furthermore, the thumb area includes a connected part I and part II, the part I is a hollow cylindrical shape with upper and lower openings, and the part II is an arc-shaped surface that bends outward; the part II is connected to one end of the thenar area, and the thenar area is an arc-shaped surface; the other end of the thenar area is connected to the wrist area, and the wrist area is a hollow cylindrical shape with upper and lower openings.

[0012] In the fixing fixture provided by the utility model, in order to adapt to the structural shapes of the thumb, thenar and wrist parts of the human body, the shapes of the thumb area, thenar and wrist areas are limited, so that the thumb area can achieve a direct fixing effect on the thumb area, and thenar and wrist areas can achieve auxiliary fixing effects and wearing effects. Specifically: the thumb area is divided into part I and part II. After the user's thumb is inserted into the thumb area, the two phalanges of the thumb are both located in the hollow cylindrical part I. Part I can limit the movement of the interphalangeal joint. Since the metacarpophalangeal joint below the proximal phalanx is more prominent, part II with an arcuate surface shape bent outward is set, and the movement of the metacarpophalangeal joint is limited by part II. Since the fixing fixture only needs to limit and fix the thumb, it is not necessary to fully support the hand. Therefore, part II and the thenar area are set to an arcuate surface shape, which can support the part below the thumb without affecting other fingers and palm parts. Since part I is cylindrical and part II is arc-shaped, the connection between the inner edges of part I and part II forms a "human" shape, which is located at the connection between the inner root of the thumb and the palm after the fixing clamp is worn, so that the fixing clamp can be stuck at the connection; and the wrist area is set to a hollow cylindrical shape, so that the lower part of the fixing clamp can be put on the user's wrist, which can increase the wearing stability.

[0013] Furthermore, the little finger area is in the shape of a hollow cylinder with openings at the top and bottom, the little finger area is connected to one end of the hypothenar area, the hypothenar area is in the shape of an arc surface, the other end of the hypothenar area is connected to the wrist area, and the wrist area is in the shape of a hollow cylinder with openings at the top and bottom.

[0014] In the fixing clamp provided by the present invention, in order to adapt to the structural shapes of the little finger, hypothenar and wrist parts of the human body, the shapes of the little finger area, hypothenar area and wrist area are limited, so that the little finger area can achieve a direct fixing effect on the little finger area, and the hypothenar area and wrist area can achieve auxiliary fixing effect and wearing effect. Specifically: after the fixing clamp is worn, the three phalanges of the little finger are all located in the little finger area with a hollow cylindrical shape, and the little finger area can limit the movement of the interphalangeal joint; because the fixing clamp only needs to limit and fix the little finger, it is not necessary to fully support the hand, so the hypothenar area is set to an arc surface shape, which can support the part below the little finger without affecting other fingers and palm parts. Since the little finger area is cylindrical and the hypothenar area is an arc-shaped surface, the connection between the inner edges of the little finger area and the hypothenar area will form a "human"-like shape, which is located at the connection between the base of the little finger and the base of the ring finger after the fixing clamp is worn, so that the fixing clamp can be clamped at the connection; and the wrist area is set to a hollow cylindrical shape, so that the lower part of the fixing clamp can be put on the wrist of the user, which can increase the wearing stability.

[0015] Furthermore, an opening with adjustable width is provided in the wrist region, and the width of the opening is directly proportional to the size of the wrist region.

[0016] In the fixing clamp provided by the utility model, an opening is arranged in the wrist area, so that the fixing clamp is easy to wear and helps to flexibly adjust the size and shape of the wrist area during thermoplasticization.

[0017] Furthermore, an opening with adjustable width is provided in the part I, and the width of the opening is directly proportional to the size of the part I.

[0018] In the fixing fixture provided by the utility model, an opening is arranged in the part I, so as to facilitate the flexible adjustment of the size and shape of the part I during thermoplasticization.

[0019] Furthermore, an opening with adjustable width is provided in the little finger area, and the width of the opening is directly proportional to the size of the little finger area.

[0020] In the fixing fixture provided by the utility model, an opening is arranged in the little finger area, so as to facilitate flexible adjustment of the size and shape of the little finger area during thermoplasticization.

[0021] Furthermore, the fixed frame is made of a soft strip material.

[0022] In the fixing fixture provided by the utility model, the fixing frame is set to be a soft strip material, so as to adapt to the shape and size changes of the positioning film.

[0023] Furthermore, the outer surface of the fixed frame is covered with fluff, and the inner surface of the fixed frame is provided with adhesive.

[0024] In the fixing clamp provided by the utility model, the outer surface of the fixing frame is covered with fluff, which can increase the comfort of the user; and the inner surface of the fixing frame is provided with adhesive, which is convenient for connecting the fixing frame to the outer edge of the positioning film.

[0025] The beneficial effects achieved by the utility model are:

[0026] A thumb fixation brace is provided. By setting a thumb area adapted to the thumb of a human body, a thenar area adapted to the thenar area of ​​a human body, and a wrist area adapted to the wrist of a human body, the fixation clamp can be worn on the hand of a user, and the thumb area of ​​the fixation clamp can limit and fix the thumb of the user. Compared with the traditional positioning film in the form of a flat diaphragm and the existing fixation clamps for the main areas of the human body, the thumb fixation brace proposed by the utility model is targeted at the specific part of the thumb, and has a basic shape adapted to the thumb of a human body, so that only the shape of the fixation clamp needs to be fine-tuned during thermoforming, and a good limit and fixation effect can be guaranteed.
