Description

Technical Field

[0001] The invention relates to a traditional Chinese medicine splint external fixation treatment system, and in particular to a traditional Chinese medicine splint component. Background Art

[0002] For a long time, the inability to adjust length and curvature instantly has been a pain point of traditional Chinese medicine splints. Existing Chinese medicine splints are made of polymer materials, and through structural mechanics, they achieve the same mechanical characteristics as natural material splints, such as the mechanical characteristics of fir bark splints and willow splints, which are "orthogonal anisotropy with axial force as the main force". Compared with the two, existing Chinese medicine splints produced using modern industrial technology have been proven to be superior to natural material splints in clinical practice, and meet the requirements of the treatment principles of Chinese medicine bone setting such as "combination of dynamic and static" and "elastic fixation", and have stable mechanical properties and good therapeutic effects, but it is also difficult to solve the problem of instant adjustment of length and curvature.

[0003] One of the principles of TCM splints for treating fractures is to use a three-point extrusion method to externally fix the fractures. The external lever corresponds to the internal lever, and there is a match between the internal and external levers. The mechanical strength of the callus is compatible with the axial stiffness of the splint fixation. Therefore, the shape of the splint is also adaptable to ensure the effectiveness of the lever force of the fracture external fixation. Due to the differences in fracture location, type, degree, age, physique, height and body position, it is necessary to adjust the length of the splint adaptively while maintaining a certain stiffness during clinical use, and bend it according to the changes in body position to form a certain curvature. Unlike plaster and plaster splints, which can be made according to the needs of the length and curvature during production, the length and curvature of the TCM splint can only be processed in advance by cutting, sawing and planing tools to meet the needs of clinical treatment, which is both time-consuming and labor-intensive. This problem has always plagued the TCM orthopedics community.

[0004] The existing small splints are manufactured by molds and assembled into splint components in the form of production parts. The finished products are fixed and need to be prepared in multiple models to meet clinical needs. Although the existing small splint technology can determine the range of fracture fixation through X-ray recognition by software, the length and curvature of the splint cannot be adjusted immediately, and matching products can only be found in the splint models with standardized shaping, which brings inconvenience to clinical treatment.

[0038] Specifically, if Figures 1 to 6As shown, in the thickness direction of the small splint component of traditional Chinese medicine, the middle groove plate body 3 is located between the upper groove plate body 2 and the bottom groove plate body 4. The upper groove plate body 2 includes a distal splint and a proximal splint, and the distal splint is connected to the proximal splint and the connection position of the distal splint and the proximal splint is adjustable, so that the length of the upper groove plate body 2 can be adjusted, so as to adapt to the external fixation treatment needs of different patients with different arm lengths. The middle groove plate body 3 is plug-connected with the distal splint and the proximal splint. When adjusting the length of the upper groove plate body 2, the middle groove plate body 3 can move relative to the distal splint and the proximal splint. The proximal section splint includes a first splint body 201, a longitudinal elastic plate 202 arranged on the first splint body 201 and a slide buckle 203 arranged on the longitudinal elastic plate 202.

The distal section splint has a length prompting groove 205 for the slide buckle 203 to be embedded. A plurality of length prompting grooves 205 are provided and the plurality of length prompting grooves 205 are arranged in sequence along the length direction of the distal section splint. The longitudinal elastic plate 202 is fixedly connected to the first clamping plate body 201, and the length of the longitudinal elastic plate 202 is smaller than the length of the first clamping plate body 201.

There is a certain distance between the two longitudinal elastic plates 202. The connection between the longitudinal elastic plate 202 and the first clamping plate body 201 can produce elastic deformation. The longitudinal elastic plate 202 has a certain amount of elastic deformation. Under the action of external force, the longitudinal elastic plate 202 can be deflected relative to the first clamping plate body 201 and swing toward the outside or inside of the first clamping plate body 201. Two slide buckles 203 are provided, and the two slide buckles 203 are located on the same straight line perpendicular to the width direction of the first clamping plate body 201 (that is, the width direction of the upper groove plate body 2). The two slide buckles 203 are respectively used to be inserted into two length prompting grooves 205, and the two length prompting grooves 205 are located on the same straight line parallel to the width direction of the distal clamping plate, so as to realize the connection between the near clamping plate and the distal clamping plate. The two slide buckles 203 are provided on the two longitudinal elastic plates 202, and the two slide buckles 203 extend toward the outer side or the inner side (the side where the first accommodating groove 204 is located) of the longitudinal elastic plate 202. After the two slide buckles 203 are inserted into the two length prompting grooves 205 at different positions in the length direction of the distal clamping plate, the length of the upper groove plate body 2 can be adjusted, and the length of the upper groove plate body 2 can also be fixed, and the distal clamping plate and the near clamping plate can no longer move relative to each other.

[0039] like Figures 1 to 6As shown, the near section splint also includes a first side groove buckle 216 arranged on the first splint body 201, and the middle groove plate body 3 has a first side slide groove 303 for the first side groove buckle 216 to be embedded in. A plurality of first side groove buckles 216 are provided, and all first side groove buckles 216 are arranged in two rows on the first splint body 201 and the first side groove buckles 216 in the two rows are symmetrically arranged, and all first side groove buckles 216 in the same row are arranged in sequence along the length direction of the first splint body 201 (that is, the length direction of the near section splint), and two first side slide grooves 303 are provided on the middle groove plate body 3, and the two rows of first side groove buckles 216 are respectively embedded in the two first side slide grooves 303 on the middle groove plate body 3, and the first side groove buckles 216 and the first side slide grooves 303 play a guiding role, which is used to guide the middle groove plate body 3 to move linearly relative to the near section splint.

The first side slide groove 303 extends along the entire length direction of the middle groove plate body 3. Two first side slide grooves 303 are arranged on two opposite outer wall surfaces of the middle groove plate body 3, and the first side groove buckle 216 is a rectangular block structure.

[0040] like Figures 1 to 6As shown, the distal clamping plate is detachably connected to the proximal clamping plate, and the slide buckle 203 can be pulled out from the length prompting groove 205. The distal clamping plate includes a second clamping plate body 211 and a second side groove buckle 212 disposed on the second clamping plate body 211 and used to be embedded in the first side slide groove 303 of the middle groove plate body 3. A plurality of second side groove buckles 212 are provided, and the length prompting groove 205 is provided on the second clamping plate body 211. The second clamping plate body 211 has a second accommodating groove for accommodating the middle groove plate body 3 and the bottom groove plate body 4. The second splint body 211 is a structure with a U-shaped cross-section (the cross-section refers to the cross-section perpendicular to the length direction of the second splint body 211). The length prompt groove 205 is a groove that is arranged on the side wall of the second splint body 211 along the thickness direction of the side wall. The length prompt groove 205 is connected to the second accommodating groove. A plurality of length prompt grooves 205 are arranged. All length prompt grooves 205 are arranged in two rows on the second splint body 211, and the two rows of length prompt grooves 205 are arranged symmetrically. All length prompt grooves 205 in the same row are arranged in sequence along the length direction of the second splint body 211 (that is, the length direction of the distal splint). The second accommodating groove is located between the two rows of length prompt grooves 205. The number of length prompt grooves 205 is more than the number of slide buckles 203. The two slide buckles 203 are respectively embedded in the two length prompt grooves 205 to achieve the fixation of the distal splint and the proximal splint. A plurality of second side groove buckles 212 are provided, and all the second side groove buckles 212 are arranged in two rows on the second clamping plate body 211, and the second side groove buckles 212 in the two rows are arranged symmetrically.

[0041] When the length of the upper groove plate body 2 needs to be adjusted, the two longitudinal elastic plates 202 are pulled outward to loosen the slide buckle 203, and then the slide buckle 203 is pulled out from the length prompting groove 205, and then the distal section splint and the proximal section splint can be separated, and after changing the connection position of the distal section splint and the proximal section splint, the upper groove plate body 2 is adjusted to a suitable length, and the two longitudinal elastic plates 202 are restored to the initial position under the action of their own elastic force, and the two slide buckles 203 are embedded in the two length prompting grooves 205 to achieve relative fixation of the distal section splint and the proximal section splint, that is, to achieve the overall length adjustment of the Chinese medicine small splint component. This structure is convenient for adjusting the length of the Chinese medicine small splint component, has a simple structure, and is easy to operate.

[0042] like Figure 5 and Figure 6 As shown, the middle trough plate body 3 has a first bridge deck 301 and a first vertical plate 302 connected to the first bridge deck 301 and extending toward one side of the first bridge deck 301, the first vertical plate 302 is a T-shaped structure and a plurality of first vertical plates 302 are arranged, all of the first vertical plates 302 extend toward the same side of the first bridge deck 301, all of the first vertical plates 302 are arranged in sequence along the width direction of the first bridge deck 301 (that is, the width direction of the middle trough plate body 3), the first vertical plates 302 and the first bridge deck 301 are extended in the same direction and the length directions of the first vertical plates 302 and the first bridge deck 301 (that is, the length direction of the middle trough plate body 3) are parallel. The bottom trough plate body 4 has a second bridge panel 401 and a second vertical plate 402 connected to the second bridge panel 401 and extending toward one side of the second bridge panel 401. The second vertical plate 402 is a T-shaped structure and a plurality of second vertical plates 402 are provided. All second vertical plates 402 extend toward the same side of the second bridge panel 401. All second vertical plates 402 are arranged in sequence along the width direction of the second bridge panel 401 (that is, the width direction of the bottom trough plate body 4). The second vertical plates 402 extend in the same direction as the second bridge panel 401 and the length direction of the second vertical plates 402 and the second bridge panel 401 (that is, the length direction of the bottom trough plate body 4) are parallel. Each second vertical plate 402 is inserted between each two adjacent first vertical plates 302. The first vertical plate 302 and the second vertical plate 402 are located between the first bridge panel 301 and the second bridge panel 401. The first side slide groove 303 is arranged on the two opposite outer wall surfaces of the first bridge panel 301. A second vertical plate 402 is inserted between each two adjacent first vertical plates 302, and a first vertical plate 302 is also inserted between each two adjacent second vertical plates 402. A T-shaped slide groove is formed between each two adjacent first vertical plates 302, and the second vertical plate 402 is embedded in the T-shaped slide groove; a T-shaped slide groove is formed between each two adjacent second vertical plates 402, and the first vertical plate 302 is embedded in the T-shaped slide groove, so as to realize the plug-in connection between the middle groove plate body 3 and the bottom groove plate body 4, so that the middle groove plate body 3 and the bottom groove plate body 4 can only move relative to each other along the length direction, forming a combination of the middle and bottom groove plate structures, and forming the length change of the clamping plate body by twitching, and maintaining the mechanical characteristics and axial stiffness of "orthogonal anisotropy with axial force as the main force". In the thickness direction, the middle groove plate body 3 and the bottom groove plate body 4 will not move relative to each other. The length of the inner splint assembly formed by the plug-in connection between the middle groove plate body 3 and the bottom groove plate body 4 can be adjusted along with the length adjustment of the upper groove plate body 2, so that the splint component can maintain the mechanical characteristics and axial stiffness of "orthogonal anisotropy with axial force as the main force". If the length of the upper groove plate body 2 increases, the length of the inner splint assembly also increases; if the length of the upper groove plate body 2 decreases, the length of the inner splint assembly also decreases.

[0043] When one bottom groove plate body 4 is provided, the bottom groove plate body 4 is fixedly connected with the distal segment splint or the proximal segment splint. A projection 1 is provided on the bottom groove plate body 4, and the upper groove plate body 2 has a slot for inserting the projection 1, and the projection 1 is inserted into the slot, and the projection 1 and the slot are tightly matched, thereby realizing the fixed connection between the bottom groove plate body 4 and the upper groove plate body 2, and the lengths of the bottom groove plate body 4 and the middle groove plate body 3 are both less than the length of the upper groove plate body 2. When such a small splint member of traditional Chinese medicine is used for external fixation treatment of long tube bone fractures, the splint member can be adjusted according to the required fixed length of the affected limb. When adjusting the length, first grasp one end of the splint member without the bottom groove plate body 4, pull and twitch the other end, and let the sliding buckle 203 of the socket end of the proximal segment splint of the upper groove plate body 2 at one end slide in the length prompting slot 205 of the distal segment splint, and calculate the length size increase and decrease data by the number of length prompting slots 205 moving to achieve a satisfactory length. Since the distal clamp is inserted into the first receiving groove 204 of the proximal clamp, the sliders 203 on the longitudinal elastic plates 202 on both sides can stably slide on the inner or outer surface of the length prompt groove 205. One end of the upper groove plate 2 is linked to the middle groove plate 3 to move; since the protrusion 1 of the bottom groove plate 4 is inserted into the slot of the upper groove plate 2 and fixed, the bottom groove plate 4 cannot move with the middle groove plate 3, and slides outward from the middle groove plate 3. The outward sliding section of the bottom groove plate 4 is combined with the longitudinal reinforcement structure on the surface of the upper groove plate 2 to form an extension of the clamp member and maintain the axial rigidity of the clamp member. On the contrary, when one end of the upper groove plate 2 is pushed inward, the middle groove plate 3 slides inward, shortening the length of the clamp member.

[0044] When two bottom groove plates 4 are provided, Figures 1 to 8As shown, the distal clamp is connected to one bottom groove plate body 4, the proximal clamp is connected to another bottom groove plate body 4, and the two bottom groove plate bodies 4 are plug-connected to the same middle groove plate body 3. The bottom groove plate body 4 does not move with the middle groove plate body 3. The immobile bottom groove plate body 4 and the upper groove plate body 2 form a length change zone of the clamp member and maintain the axial rigidity of the clamp. A protrusion 1 is provided on the bottom groove plate body 4, and the protrusion 1 is fixedly connected to the second bridge deck 401. The protrusion 1 and the second vertical plate 402 extend toward the same side of the second bridge deck 401. The protrusion 1 is located at one end of the second bridge deck 401 in the length direction. The protrusion 1 is a rectangular block structure. A plurality of protrusions 1 are provided, and all protrusions 1 are arranged in sequence along the width direction of the second bridge deck 401. A first slot 210 for the protrusion 1 to be embedded in is set on the near section clamp, and the number of the first slots 210 is the same as the number of the protrusions 1, and a protrusion 1 is embedded in each first slot 210. For the bottom slot plate body 4 connected to the near section clamp, the protrusion 1 set on the bottom slot plate body 4 is tightly matched with the first slot 210. After the protrusion 1 is embedded in the first slot 210, the bottom slot plate body 4 and the near section clamp can be fixedly connected. One end of the middle slot plate body 3 is inserted between the bottom slot plate body 4 and the near section clamp, and the middle slot plate body 3 is slidably connected with the bottom slot plate body 4 and the near section clamp. A second slot 215 for the protrusion 1 to be embedded in is set on the distal clamping plate, and the number of the second slots 215 is the same as the number of the protrusions 1, and a protrusion 1 is embedded in each second slot 215. For the bottom slot plate body 4 connected to the distal clamping plate, the protrusion 1 set on the bottom slot plate body 4 is tightly matched with the second slot 215. After the protrusion 1 is embedded in the second slot 215, the bottom slot plate body 4 and the distal clamping plate can be fixedly connected. The other end of the middle slot plate body 3 is inserted between the bottom slot plate body 4 and the distal clamping plate, and the middle slot plate body 3 is slidably connected with the bottom slot plate body 4 and the distal clamping plate.

[0045] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, two protrusions 1 are provided, and correspondingly, two first card slots 210 and second card slots 215 are also provided. The first card slot 210 and the second card slot 215 are rectangular slots. The first card slot 210 is provided through the thickness direction of the first clamping plate body 201, and the second card slot 215 is provided through the thickness direction of the second clamping plate body 211.

[0046] like Figures 1 to 4 As shown, the slide buckle 203 extends toward the inner side of the longitudinal elastic plate 202 , that is, the slide buckle 203 extends into the first receiving groove 204 , and one end of the distal clamping plate is also inserted into the first receiving groove 204 .
