Description

Technical Field

[0001] This utility model relates to the field of fracture fixation device technology, and in particular to an extension-type distal radius fracture splint device. Background Technology

[0002] Extension-type distal radius fractures are usually caused by accidentally supporting the ground with the palm of the hand during an injury. During the fracture, the distal fragments may also shift in position.

[0003] Clinically, the main treatment involves setting up pads, splints, etc. after reduction to fix the hand in a slightly downward flexed position from the radial side to the ulnar side, i.e., palmar flexion and ulnar deviation.

[0004] Traditional plaster casts can prevent the affected area from shifting, but plaster fixation tightly wraps the fracture site, making it virtually impossible for the patient to move. Some patients may experience swelling at the site, and plaster fixation can also compress the affected area to some extent, affecting healing. In addition, because the affected area is tightly wrapped with plaster gauze, patients are prone to complications such as soft tissue scar adhesions and limited mobility. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a straightening-type distal radius fracture splint device that can reduce soft tissue scarring and other related complications caused by plaster wrapping and clamping at the fracture fixation site.

[0006] The technical solution of this utility model is as follows:

[0007] An extension-type distal radius fracture splint device, comprising

[0008] The first soft plate is fitted to the back of the hand at the distal radius, and the entire first soft plate extends from the arm beyond the wrist.

[0009] The first splint is located on the outside of the first soft plate. The first splint extends from the arm beyond the wrist. The portion of the first splint that extends beyond the wrist bends downward and its end rests against the back of the hand to provide downward pressure from the back of the hand.

[0010] The second splint is fitted to the radial side of the distal radius. The second splint extends from the arm beyond the wrist, and its end rests against the radial side of the hand, thereby generating a force toward the ulnar side.

[0011] And fasteners, used for securing and positioning soft boards and plywood.

[0012] Based on the above technical solution, a soft plate is used in conjunction with two sets of splints, and fixation devices are used to effectively fix the fracture of the distal radius in an extension type. The soft plate is elastic and the plate-like material has a certain tear resistance. After fixation and restraint, the affected area is in a non-rigid contact state, which ensures fixation strength while allowing slight movement, which is conducive to the healing of the affected area and reduces the pressure on the tissues.

[0013] Furthermore, a third splint is placed on the palmar side of the distal radius, and the end of the third splint does not extend beyond the wrist.

[0014] Based on the above technical solution, setting a third splint can work in conjunction with the first splint to strengthen the clamping and fixation effect on the fracture site.

[0015] Furthermore, a fourth splint is placed on the ulnar side of the distal radius, with the end of the fourth splint not exceeding the wrist.

[0016] Based on the above technical solution, it is convenient to work with the second clamp to strengthen the fixation of the wrist in the horizontal direction (lateral direction).

[0017] Furthermore, a soft plate is provided on the inner side of the third and / or fourth splints, fitting against the arm, and the end of the corresponding soft plate does not extend beyond the wrist.

[0018] Based on the above technical solution, the use of a soft plate can reduce tissue pressure at the splint and improve clamping and fixation capabilities.

[0019] Furthermore, the thickness of the flexible board is 0.1-5mm.

[0020] Based on the above technical solution, a flexible board of suitable thickness is convenient for shaping and operation during subsequent fixing.

[0021] Furthermore, the soft board is a fiber composite board or a silicone board.

[0022] Furthermore, the plywood material is willow board, bamboo board, or plastic board.

[0023] Based on the above technical solution, it is convenient to obtain materials.

[0024] Furthermore, a pad is placed on the inside of the flexible board.

[0025] Based on the above technical solutions, the fracture site can be further buffered and protected, thereby reducing pressure on the tissues.

[0026] Furthermore, a stacked structure is formed at the end of the back side of the first soft wrench, and the stacked structure has gaps.

[0027] Based on the above technical solution, the stacked structure can provide enhanced positioning of the fracture site; and the stacked structure has a small number of gaps, which provides some room for movement and helps to further reduce tissue compression in the affected area when swelling occurs.

[0028] Furthermore, a dividing groove is provided at least at the end of the soft plate near the wrist.

[0029] Based on the above technical solution, it is convenient to subsequently shrink and overlap the end near the wrist to form a stacked structure, which is also conducive to operation and fixation, and easy to adjust and fix. Similarly, the end on the arm side is provided with a partition groove, and the soft plate end near the arm is separated. During local activities, it can be slightly stretched and moved, which can reduce pressure on the arm. At the same time, after the soft plates at this end are separated, it is also easy to apply to the arm, increasing the overall coverage area. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] Reference Figure 1-3 A splint fixation device for distal radius fractures with extension, comprising:

[0041] The first soft plate 11 is fitted and disposed on the back of the hand at the distal end of the radius, and the first soft plate 11 extends from the arm and beyond the wrist.

[0042] The first splint 21 is disposed on the outside of the first soft plate 11. The first splint 21 extends from the arm and beyond the wrist. The portion of the first splint 21 extending beyond the wrist bends downward and its end abuts against the back of the hand to provide downward pressure from the back of the hand.

[0043] The second splint 22 is fitted and placed on the radial side (closer to the inner side of the body) of the distal radius. The second splint 22 extends from the arm beyond the wrist, and its end rests against the radial side of the hand to conform to the curve of the human hand, thereby generating a force toward the ulnar side to promote the positioning of the affected area.

[0044] And fixation component 4, used to fasten the soft plate and splint, thereby binding and securing it to the fracture site. Clinically, fixation component 4 is often made of binding straps and medical tape, which are wrapped around the outside of the soft plate and splint along the arm and palm and tied for fixation.

[0045] like Figure 1 A second soft plate 12 can be further provided, which is fitted to the palmar side of the distal radius, and the second soft plate 12 extends from the arm without exceeding the wrist; a third splint 23 can be further provided, which is fitted to the second soft plate 12 and does not extend beyond the wrist, and can work with the first soft plate 11 and the first splint 21 to form a clamping and fixing effect on the wrist in the height direction (longitudinal direction).

[0046] Similarly, such as Figure 3 To fix the wrist in the horizontal direction (lateral direction), a fourth clamp 24 can also be set on the corresponding ulnar side (outer side away from the body) of the second clamp 22, with the end of the fourth clamp 24 not exceeding the wrist.

[0047] The soft boards 11 and 12 are configured as elastic, soft (flexible) board-shaped materials that are easy to bend and have a certain degree of elasticity and tear resistance to ensure binding force. The thickness of the soft board is preferably 0.1-5mm, more preferably 0.5-3mm, and can be a single sheet or multiple sheets combined. In some embodiments of this application, (paper) fiber composite boards or silicone sheets are used. At the same time, the total length of the soft board can be adapted to the length of the patient's arm to ensure sufficient binding force, and the end of the soft board near the arm should not exceed the elbow, generally 1 / 2-4 / 5 of the forearm length.

[0048] Splints 21, 22, 23, and 24 have a certain degree of hardness and toughness. Their materials can be willow boards, bamboo boards, or plastic boards, etc., as the basis for limiting and fixing the affected area. When fixing in clinical practice, the curvature of the splint can be set according to the patient's body shape and the curve adaptability of the affected area. For example, bamboo boards can be heated and calcined to promote bending.

[0049] Of course, padding 3 can be further placed at the fracture site; for extension-type distal radius fractures, the first splint 21 bends downwards from the back of the hand, so it is generally placed near the radius side of the back of the hand to further cushion and protect the fracture site, thereby reducing pressure on the tissues. Padding 3 can be filled with cotton gauze folded and wrapped, or other elastic fillers; and drug delivery points can be further placed on the inside of padding 3, such as applying traditional Chinese medicine patches to promote fracture healing and reduce side effects. At the same time, padding can also be placed at the clamping and positioning points of splints 21-24 to reduce tissue pressure in other areas.

[0050] In addition, a soft plate could be further provided on the sides of the wrist (radial and ulnar sides), but considering that the thickness of the sides of the wrist is relatively thin, the soft plate on the sides is omitted in this embodiment.

[0051] like Figure 4-5 As shown, a partition groove 5 is provided at the end of the soft plates 11 and 12 to form several locally separated parts at the end of the soft plates, which facilitates application; at the same time, it is also convenient to locally shrink and overlap the end near the wrist, so that the soft plates form a locally thickened stacked structure 6 at the end; since the soft plates in this stacked structure 6 are separated from each other and have a certain gap between them, they can accommodate slight wrist movements and reduce pressure; similarly, a partition groove 5 is provided on the arm side, and the soft plate end near the arm is separated, which can be slightly stretched during local movements, which can reduce pressure on the arm. At the same time, after the soft plates at this end are separated, they are also easy to apply to the arm, increasing the overall coverage area.

[0052] The number of partition slots 5 can be set according to the width of the soft board, and generally 2-4 slots are sufficient to meet the requirements.

[0053] Of course, a stacked structure can also be multiple flexible boards stacked locally, thus forming a stacked structure with a small number of gaps.

[0054] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
