Background Art

[0002] The treatment of fractures with a small splint in traditional Chinese medicine is a fracture therapy with Chinese characteristics. It organically combines fracture reduction, fixation and functional exercise, and has achieved good results in fracture healing and functional recovery. However, in clinical practice, skin pressure sores, tension blisters, and local infections are common complications of the treatment of fractures with a small splint in traditional Chinese medicine. Skin damage and post-operative injuries without wound healing are contraindicated for external fixation medical devices, including small splint external fixation. Existing traditional Chinese medicine small splint external fixation treatment devices are all made of opaque materials. After external fixation, it is difficult to observe the skin condition under the splint, which often leads to skin tissue damage and infection. In particular, traditional small splint external fixation adopts a dense bundling method.

The first inner splint has a plurality of specifications with different rigidity and / or length. The first inner splint can be selected with specifications with different rigidity, or with specifications with different lengths, or with specifications with different lengths and rigidity, to form an adjustable splint component, that is, it can adapt to the external fixation treatment needs of different patients with different arm lengths and splint rigidity. In order to achieve the axial fixation stiffness of the splint to be compatible with the mechanical strength of the callus, the splint can convert muscle kinetic energy in the transverse direction to the maximum area to generate a restoring force, which fully reflects the treatment principle of "combining movement and stillness, and paying equal attention to tendons and bones" of the small Chinese medicine splint, while also avoiding the limitation of the manufacturing process. When in use, the length of the first outer splint can be determined according to the length of the patient's limb by cutting the length of the upper section of the first splint and / or the lower section of the first splint, and the first inner splint of suitable length and stiffness can be rotated accordingly, and the first outer splint and the first inner splint are combined to form the first splint body through the first clamping seat to increase the stiffness.

When it is necessary to adjust the length of the first outer clamping plate, the first buckle 309 is loosened by pulling the first buckle 309 outward, and then the first buckle 309 is pulled out of the first avoidance groove 310, and then the first clamping seat can be separated from the upper section of the first clamping plate and the lower section of the first clamping plate, and finally after cutting the length of the upper section of the first clamping plate and / or the lower section of the first clamping plate, the upper section of the first clamping plate and the lower section of the first clamping plate are fixed to the first inner clamping plate through the first clamping seat.

There is no need to produce multiple splints of different lengths. Arbitrary cutting can reduce storage volume, and the use is flexible and convenient.

[0104] like Figures 1 to 5As shown, the transverse coupling device also includes a guide member 9 arranged on the second clamping plate, and the guide member 9 is made of a transparent material, and the guide member 9 is completely transparent as a whole. The first shaping track 7 and the second shaping track 8 pass through the guide member, and the first shaping track 7 and the second shaping track 8 are fixedly connected, and the guide member is clamped between the second middle limiter 413 and the second clamping seat. The guide member passes between the second vertical portion of the second middle limiter 413 and the second bottom plate 408, and the first vertical portion of the second middle limiter 413 is embedded in the first slide groove of the first shaping track 7 and the second slide groove of the second shaping track 8. The guide member 9 is a member with openings at both ends and a hollow interior. The guide member 9 is fixed between the second middle limit member 413 and the second bottom plate 408. The guide member 9 has a certain length and the length direction of the guide member 9 is parallel to the width direction of the second clamping plate body. Two parallel guide members are provided. The first vertical portion of the second middle limit member 413 is located between the two guide members. The first shaping track 7 and the second shaping track 8 are fixedly connected to form an integrated structure. The guide member 9 guides the first shaping track 7 and the second shaping track 8 and is used to guide the first shaping track 7 and the second shaping track 8 to move. The guide member 9 also protects the first shaping track 7 and the second shaping track 8. The first shaping track 7 and the second shaping track 8 connect the first clamping plate, the second clamping plate, and the third clamping plate into one. The material of the first shaping track 7 and the second shaping track 8 can be the same as that of the guide member 9, and is made of polymer material. The first shaping track 7 and the second shaping track 8 are fully transparent as a whole.

[0105] like Figure 1 , Figure 28 to Figure 31 As shown, the TCM splint external fixation device of the present invention further includes a locking device, which includes an insert 11, a locking support 10 connected to the insert 11, and a clamping member rotatably disposed on the locking support 10 and used to cooperate with the locking support 10 to clamp the strap.

[0106] The insert 11 is made of a transparent material, preferably a transparent polymer material, and the insert 11 is a fully transparent structure as a whole. The locking support 10 is made of a transparent material, preferably a transparent polymer material, and the locking support 10 is a fully transparent structure as a whole. The clamping piece is made of a transparent material, preferably a transparent polymer material, and the clamping piece is a fully transparent structure as a whole.

[0107] The locking support 10 has a first avoidance hole 16 and a second avoidance hole 17 for the strap to pass through, and the clamping member includes a rotating plate 12 rotatably connected to the locking support 10, and a first clamping plate 13 arranged on the rotating plate 12 and used to be inserted into the first avoidance hole 16, a second clamping plate 14 used to be inserted into the second avoidance hole 17, and a lock hook plate 15 used to keep the clamping member and the locking support in a buckled state. The insert 11 is used to be inserted into the fifth slot, which is a groove arranged on the fourth clamping seat or the tension prompting device, and the insert 11 is connected to the fourth clamping seat or the tension prompting device, thereby forming a connection with the fourth clamping plate. The straps 1 are provided with three in total, two of which have one end fixedly connected to the fourth buckle ring 603, and another end fixedly connected to the fourth middle buckle ring 610. The other ends of the three straps 1 are free ends. When in use, the straps 1 fasten the first splint 3, the second splint 4, the third splint 5 and the fourth splint 6 to the human forearm. After the free end of the strap 1 passes through the first splint 3, the second splint 4, the third splint 5 and the locking device in sequence, it can then pass through the third splint 5, the second splint 4 and the first splint 3 in sequence. After the restraining force of the strap is adjusted to an appropriate size, the locking device is finally used to clamp the strap so that the circumference of the strap is fixed (the circumference of the strap refers to the length between the fixed end of the strap fixedly connected to the fourth buckle ring 603 (or the fourth middle buckle ring 610) and the part of the strap clamped by the locking device), and the fourth buckle ring 603 and the fourth middle buckle ring 610 are on the same straight line parallel to the length direction of the fourth splint.

[0108] like Figure 28 to Figure 31As shown, the insertion piece 11 is rotatably connected to the locking support 10. The locking support 10 is rotatable relative to the insertion piece 11, and the rotation center line during the rotation of the locking support 10 is parallel to the length direction of the fourth clamping plate. The locking support 10 is located outside the fourth clamping plate. The rotating plate 12 is rotatably connected to the locking support 10. The rotating plate 12 is rotatable relative to the locking support 10, and the rotation center line of the rotating plate 12 is parallel to the length direction of the fourth clamping plate. The first avoidance hole 16 and the second avoidance hole 17 are through holes penetrating through the locking support 10. The first avoidance hole 16 is located between the insertion piece 11 and the second avoidance hole 17. The first avoidance hole 16 and the second avoidance hole 17 have a certain length, and the length direction of the first avoidance hole 16 and the second avoidance hole 17 is parallel to the rotation center line of the rotating plate 12. The lengths of the first avoidance hole 16 and the second avoidance hole 17 are greater than the width of the strap, and the lengths of the first avoidance hole 16 and the second avoidance hole 17 are the same, forming a locking support 10 that is roughly in the shape of a Chinese character 'Ri'. During use, the free end of the strap passes through the third clamping plate 5 in sequence and then through the first avoidance hole 16 of the locking support 10. Then, the free end of the strap is folded back and passed through the second avoidance hole 17 of the locking support 10. After the free end of the strap passes out from the second avoidance hole 17, it can pass through the third clamping plate 5, the second clamping plate 4, and the first clamping plate 3 in sequence. The clamping member is arranged to be switchable between an open position and a fastening position. When the clamping member is in the open position, the clamping member can rotate freely relative to the locking support 10. At this time, the clamping member and the locking support 10 cannot clamp the strap, so that the strap can be pulled to adjust the binding force, and the strap can move in the first avoidance hole 16 and the second avoidance hole 17 of the locking support 10. After the binding force of the strap is adjusted appropriately, the clamping member is switched from the open position to the fastening position. At this time, the clamping member can cooperate with the locking support 10 to clamp the strap, and the strap cannot be pulled, so that the surrounding circumference of the strap is fixed. When the clamping member is in the open position, the first clamping plate 13 is inserted into the first avoidance hole 16, and the second clamping plate 14 is inserted into the second avoidance hole 17. The first clamping plate 13 applies a pressure to the strap to make it fit with the locking support 10, and the second clamping plate 14 applies a pressure to the strap to make it fit with the locking support 10. A part of the strap is located between the first clamping plate 13 and the second clamping plate 14. Therefore, through the cooperation of the first clamping plate 13 and the second clamping plate 14 with the locking support 10, the clamping and fixing of the strap are realized. The structure is simple and compact, the operation is convenient, the strap is not easy to loosen, and the reliability is good.The rotating plate 12 has a certain length and width, the length direction of the rotating plate 12 is parallel to its rotation center line, the length direction of the rotating plate 12 is perpendicular to its width direction, one end of the rotating plate 12 in the width direction is fixedly connected to the locking support 10, and the locking hook plate 15 is fixedly connected to the other end in the width direction of the rotating plate 12, the first clamping plate 13 and the second clamping plate 14 both have a certain length and width, the length direction of the first clamping plate 13 and the second clamping plate 14 is parallel to the length direction of the rotating plate 12, the first clamping plate 13, the second clamping plate 14 and the locking hook plate 15 extend toward the same side of the rotating plate 12 and the second clamping plate 14 is located between the first clamping plate 13 and the locking hook plate 15, the first clamping plate 13, the second clamping plate 14 and the locking hook plate 15 are arranged in sequence along the width direction of the rotating plate 12, and the first clamping plate 13 is located between the second clamping plate 14 and the end of the rotating plate 12 that is rotatably connected to the locking support 10. The width direction of the first clamping plate 13 is perpendicular to the length direction thereof, the width direction of the second clamping plate 14 is perpendicular to the length direction thereof, the width direction of the first clamping plate 13 is parallel to the width direction of the second clamping plate 14, and the width directions of the first clamping plate 13 and the second clamping plate 14 are perpendicular to the length direction and the width direction of the rotating plate 12, the width of the first clamping plate 13 is smaller than the width of the second clamping plate 14, and there is a certain distance between the first clamping plate 13 and the second clamping plate 14.

[0109] like Figure 28 to Figure 31 As shown, there is a certain distance between the lock hook plate 15 and the second clamping plate 14, and the lock hook plate 15 has a certain length and width. The length direction of the lock hook plate 15 is parallel to the length direction of the rotating plate 12, and the width direction of the lock hook plate 15 is parallel to the width direction of the second clamping plate 14. Preferably, the first end of the lock hook plate 15 is fixedly connected to the rotating plate 12, and the second end of the lock hook plate 15 is a hook-shaped structure. The first end and the second end of the lock hook plate 15 are the opposite ends in the width direction of the lock hook plate 15. The second end of the lock hook plate 15 is used to hook the locking support 10 when the clamping piece is in the buckled position, thereby keeping the clamping piece in the buckled position, keeping the clamping piece and the locking support 10 in a state of clamping the strap to prevent the strap from loosening, which is convenient, fast, safe and reliable.

[0110] The Chinese medicine small splint external fixation device of this embodiment has the following advantages:

[0111] 1. Each component is transparent, ensuring that the skin condition of the patient's fixed part can be intuitively understood;

[0112] 2. Use a single strap to facilitate the adjustment of the splint position and maintain the sensitivity of the restraining force ring; use a locking device to limit the loosening of the strap to ensure the reliability of the restraining force ring of the splint device;

[0113] 3. The transverse connection device is used to shape the entire splint device according to the transverse biological morphology of the patient's arm before external fixation. The splint is positioned according to the position where the splint should be placed. It mainly connects the first, second and third splint components. After shaping, the splint device can be placed on the affected limb from bottom to top to form a painless wearing method. The buckle and limiter structure are used to limit the random sliding of the splint.

[0114] 4. Use a track to position the splint by horizontal shaping to improve the simplicity of external fixation operation.

[0115] Embodiment 2

[0116] like Figures 32 to 40 As shown, this embodiment provides a shoulder joint external fixation device, including a shoulder wrap plate for covering a human shoulder joint and a pulling portion connected to the shoulder wrap plate, the shoulder wrap plate includes an upper splint 18, an upper extension plate 19 and a middle splint 28 located between the upper splint 18 and the upper extension plate 19, one end of the middle splint is rotatably connected to the upper splint 18, and the other end of the middle splint is rotatably connected to the upper extension plate 19, any one or more (including all) of the upper splint 18, the middle splint and the upper extension plate 19 are made of the traditional Chinese medicine small splint component of the above-mentioned structure, and the traditional Chinese medicine small splint component is made of a transparent material.

[0117] Specifically, if Figure 32 to Figure 36 As shown, the shoulder joint external fixation device of this embodiment also includes an upper swing plate 20 rotatably connected to the upper extension plate 19 and connected to the pulling part, and a lower swing plate 21 rotatably connected to the upper section splint 18 and connected to the pulling part, and the upper swing plate and the lower swing plate are made of transparent material. The shoulder wrap plate is an arc-shaped structure as a whole, and two pulling parts are provided, and the two pulling parts are provided on opposite sides of the shoulder wrap plate and the pulling parts are connected to the shoulder wrap plate.

[0118] One end of the upper extension plate 19 is rotatably connected to one end of the middle splint, and the other end of the middle splint is rotatably connected to one end of the upper splint 18, and the middle splint is rotatably connected to the end of the upper splint 18 corresponding to the upper end of the humerus on the outside of the shoulder joint through a rotating shaft. The upper extension plate 19, the middle splint and the upper splint 18 all have a certain length, and the length of the upper extension plate 19 is greater than the length of the middle splint and the upper splint 18. The shape of the upper extension plate 19 is consistent with the arc shape from the upper end of the humerus to the middle section of the clavicle on the outside of the human shoulder joint. When the shoulder joint swells to a change in curvature, the hinge structure connecting the middle splint with the upper extension plate 19 and the upper splint 18 causes the curvature of the shoulder plate to change accordingly on the outside, and always keeps consistent with the curvature of the side of the shoulder joint. The upper swing plate 20 has a certain length, and the two upper swing plates 20 are arranged opposite to each other. The two upper swing plates 20 extend toward the bottom of the upper extension plate 19. The upper extension plate 19 is located between the two upper swing plates 20, and the two upper swing plates 20 are rotatably connected to the upper extension plate 19 at one side edge of the upper extension plate 19 respectively.

[0119] After the shoulder joint Chinese medicine splint external fixation device is wrapped around the human shoulder joint, the upper splint 18 extends from the corresponding shoulder joint acromion lateral position to the corresponding humerus position below, and the upper extension plate 19 extends from the corresponding shoulder joint acromion lateral position to the position above the middle section of the clavicle. The upper extension plate 19 can rotate up and down relative to the middle splint, and the upper splint 18 can also rotate up and down relative to the middle splint, so that the arc of the shoulder wrap plate can produce adaptive changes in the longitudinal direction to maintain effective fixing force. The two upper swing plates 20 are located on the front and rear sides of the upper extension plate 19, and the upper swing plate 20 can swing back and forth relative to the upper extension plate 19. The distance between the two upper swing plates 20 can be increased or decreased to adapt to the change of shoulder joint hematoma.

The upper swing plate 20 is made of a transparent polymer material, and the upper swing plate 20 is completely transparent as a whole. The lower swing plate 21 is made of a transparent polymer material, and the lower swing plate 21 is completely transparent as a whole. After the shoulder joint external fixation device is worn on the patient's shoulder, since all the components surrounding the shoulder are completely transparent, it is convenient to intuitively understand the skin condition at the patient's shoulder.

An upper hinge seat is provided on the upper extension plate 19, and the upper hinge seat is a U-shaped hook structure. An upper hinge hole for inserting the upper hinge seat is provided at the upper end of the upper swing plate 20.

The width direction of the upper extension plate 19 is parallel to the rotation center line of the upper extension plate 19 when it rotates relative to the middle section splint. The upper hinge seat is used to be inserted into the upper hinge hole of the upper swing plate 20 laterally to form a hinge structure, so that the upper swing plate 20 can swing laterally on both sides of the upper extension plate 19. After the pulling part is connected, it can adapt to the shape change caused by swelling in the front and rear directions of the shoulder joint, and maintain effective squeezing force on the front and rear splints.

Two upper pulling plates 22 are provided, and the two upper pulling plates 22 are arranged oppositely.

When the shoulder joint hematoma causes the shoulder joint morphology to change, this combined shoulder wrap traction plate structure can produce dynamic adjustment to maintain effective fixing force on the shoulder joint.

[0125] Preferably, the upper pulling plate 22 is made of a transparent material, preferably a transparent polymer material, and the upper pulling plate 22 is completely transparent.

Each upper traction plate 22 is swung and rotated with a lower traction plate 23 and a traction connecting plate 24 on the same plane, and the compliance of the external fixation device is dynamically adjusted when the shoulder joint swells and changes, forming a dynamic balance to maintain the stability of the external fixation. The upper end of the upper traction plate 22 is rotatably connected with the upper swing plate 20 through a rotating shaft, and the lower end of the upper traction plate 22 is rotatably connected with one end of the traction connecting plate 24 through a rotating shaft.
