Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a multi-dimensional adjustable fracture fixator and a using method thereof. Background Art

[0002] Phalangeal fracture refers to the fracture of phalanges caused by direct external force or transmitted external force, such as a heavy object pressing on the dorsum of the foot, the toes hitting a hard object, etc. Factors such as long-term strain, advanced age, obesity, etc. can increase the risk of fracture. Among them, the distal phalanges have a higher probability of fracture than the proximal phalanges, and can be transverse, oblique, longitudinal fractures or comminuted fractures, often manifested as foot swelling, pain, limited movement, deformity, etc. Especially when women wear shoes, it is very easy to cause varus of the phalanges and form fractures.

[0003] After the reduction of phalangeal fractures, plaster fixation is usually required, that is, using a plaster splint that exceeds the distal end of the toes to fix the toes. Functional training can be carried out in 2-3 weeks and early walking is possible. In order to avoid secondary injury caused by the bending and pulling of the toes during the walking training process, the coverage area of the plaster will be extended to the entire foot.

[0004] The following deficiencies still exist in the prior art during the positioning of phalangeal fractures:

[0005] 1. In the existing plaster fixation technology, the full coverage of the foot by the plaster often causes poor air permeability, thus hindering the normal recovery process of the foot. Especially for women, varus of the phalanges may be caused after wearing shoes. At this time, necessary adjustment of the position of the phalanges is required. However, once the foot is fixed by the plaster, it is no longer possible to effectively adjust the phalanges, which will undoubtedly have an adverse impact on the rehabilitation of the phalanges;

[0006] 2. In addition, after phalangeal fractures, when local swelling, pain and other symptoms occur in the phalanges, it is impossible to use external medications to relieve the symptoms, which affects the rehabilitation of the phalanges;

[0007] 3. In addition, the fixed phalanges cannot be adaptively trained according to the rehabilitation situation.

[0008] In view of the above problems, the present invention document proposes a multi-dimensional adjustable fracture fixator and a using method thereof. Summary of the Invention

[0009] The purpose of the present invention is to solve the deficiencies that the full coverage of the foot by the existing plaster causes poor air permeability, it is impossible to effectively adjust the phalanges after plaster fixation, it is impossible to apply medications to the swollen and painful parts in time, and it is impossible to perform adaptive training according to the rehabilitation situation, and to propose a multi-dimensional adjustable fracture fixator and a using method thereof.

[0010] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0013] It further comprises a connection box fixed on the top of the fixing ring, and two arc-shaped clamping plates are arranged in the fixing ring, and the two arc-shaped clamping plates are close to each other for clamping and fixing the toes;

[0014] A fixing structure is arranged in the fixing ring for driving the two arc-shaped clamping plates to approach each other to clamp and fix the toes;

[0015] A positioning structure is arranged in the bottom plate for positioning the bottom plate in the sliding groove, and the fixing structure can be used to drive the positioning structure to operate;

[0016] An adjusting structure is arranged on the top of the fixing pad for driving the fixing ring to rotate to reset the fractured toe;

[0017] A medicine application structure is arranged in the connection box for applying liquid medicine to the swollen and painful parts.

[0018] In a possible design, the fixing structure includes a cavity arranged inside the fixing ring. The connecting box is communicated with the cavity. On one side of each of the two arc-shaped clamping plates away from each other, a plurality of first fixing rods are fixed. A fixing cylinder is slidably sleeved on the outer wall of each of the plurality of first fixing rods, and each of the plurality of fixing cylinders is fixed on the inner wall of the fixing ring. The fixing cylinder and the first fixing rod cooperate to control the stable movement of the arc-shaped clamping plate. On the inner walls of two sides of the fixing ring away from each other, connecting cylinders are fixed. A piston rod is hermetically and slidably connected in each of the two connecting cylinders. One ends of the two piston rods close to each other are respectively fixed to the two arc-shaped clamping plates. The two connecting cylinders are both communicated with the cavity. The gas in the cavity is injected into the connecting cylinder to drive the arc-shaped clamping plate to move for fixing and clamping the toes. A first piston plate is hermetically and slidably connected in the connecting box. A second fixing rod is fixed to the top of the first piston plate. The top end of the second fixing rod slidably extends above the connecting box and is fixed to a top plate. A threaded rod threadedly connected to the top plate is rotatably connected to the top of the connecting box, and is used to push the first piston plate downward to inject the gas in the connecting box into the cavity; by driving the threaded rod to rotate, the threaded rod drives the top plate, the second fixing rod and the first piston plate to move downward as a whole, and presses the gas in the connecting box into the cavity. As the pressure of the gas in the cavity increases, the piston rod and the arc-shaped clamping plate are pushed to move towards the middle, and thus the toes can be fixed by the arc-shaped clamping plate.

[0019] In a possible design, the positioning structure includes a first air storage cavity arranged inside the bottom plate. A second piston plate is hermetically and slidably connected in the first air storage cavity. A plurality of second pin columns are fixed to the bottom of the second piston plate. The bottom ends of the plurality of second pin columns all slidably extend below the bottom plate and are matched with the pin slots in the adjacent sliding grooves for positioning the bottom plate. The bottom of the fixing ring is fixed with an air guide pipe communicated with the cavity. The bottom end of the air guide pipe is fixedly extended into the first air storage cavity. The bottom end of the air guide pipe is located above the second piston plate and is used to inject the gas in the cavity into the first air storage cavity to control the downward movement of the second pin column; the gas in the cavity is injected into the first air storage cavity through the air guide pipe, and the second piston plate and the second pin column are pushed to move downward and inserted into the pin slots, so as to position the toe plate with the bottom plate and the fixing cushion plate, and avoid secondary injury to the toes caused by the movement of the fixing cushion plate and the fixing ring after the toes are fixed.

[0020] In a possible design, the adjustment structure includes two fixed seats fixed on the top of the fixed backing plate. The two fixed seats are respectively located on both sides of the fixed ring. Rings are fixed on both sides of the fixed ring, and the rings are slidably connected to the adjacent fixed seats to ensure the smooth rotation of the fixed ring.

By rotating the damping rotating shaft to drive the gear to rotate, the gear and the arc-shaped rack cooperate to drive the fixed ring to rotate, thereby being able to reset the everted toes. Since there is damping between the damping rotating shaft and the fixed backing plate, it can play a positioning role for the fixed ring after the damping rotating shaft rotates, avoiding the reverse reset rotation of the fixed ring.

[0021] In a possible design, the medicine application structure includes a lifting plate slidably connected in the connection box. The lifting plate is slidably sleeved on the outer wall of the second fixed rod. A plurality of vertical rods are fixed to the top of the lifting plate. The tops of the plurality of vertical rods all slidably extend to the top of the connection box and are fixed to the same dial plate, and the dial plate is sleeved on the outer wall of the second fixed rod. A medicine injection port for injecting liquid medicine is provided at the top of the connection box. Guide medicine hoses are fixedly communicated with both sides of the connection box. The lifting plate drives the liquid medicine in the connection box to move upward and be discharged to the outside through the guide medicine hoses.

When it is necessary to apply liquid medicine to the swollen and painful part, corresponding liquid medicine is injected through the medicine injection port at the top of the connection box. Then, the dial plate is toggled upward. The dial plate drives the lifting plate to move upward through the vertical rods. The lifting plate drives the liquid medicine to move upward and injects it into the through holes through the guide medicine hoses. Then, the liquid medicine wets the cotton layer pads through the through holes, thereby applying the liquid medicine to the toes, which helps promote blood circulation and remove blood stasis, reduce swelling and relieve pain of the toes.

[0022] In a possible design, a first push rod slidably penetrates through the toe backing plate, and the bottom end of the first push rod is inserted and matched with the pin slot for positioning the toe backing plate. The top end of the first push rod is fixed with a push plate. A first spring fixedly connected to the bottom of the push plate is sleeved on the outer wall of the first push rod, and the first spring is fixed to the top of the toe backing plate. The corresponding toe backing plate is slidably inserted into the sliding groove, and the remaining intact toes can just be placed on the push plate. In addition, the intact toes can complete the insertion of the first push rod and the pin slot by pressing the push plate, which helps the movement of the intact toes after the foot is fixed and promotes blood circulation in the foot.

The support member is composed of two second push rods, and the two second push rods are located on both sides of adjacent sliding grooves, and are used to push the fixed pad upward for rehabilitation training of the fractured toe. The distance between the two second push rods is greater than the width of the toe pad to avoid touching the toe pad when the second push rod pushes the fixed pad upward; the circular plate injects the air in the circular groove into the second air chamber through the L-shaped pipe and pushes the third piston plate and the second push rod upward. Correspondingly, the second push rod can push the fixed pad and the fixed ring upward for rehabilitation activities of the fractured toe.

[0025] In a possible design, a circular groove is provided at the top of the shoe plate on the side away from the toe plate. An L-shaped pipe is fixed in the shoe plate.

Detailed implementation manner

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0050] Embodiment 1: Refer to Figure 1 and Figure 2 , a fracture fixator, which relates to the technical field of medical devices. This multi-dimensional adjustable fracture fixator includes a shoe plate 1. Elastic binding bands 2 are fixed on both sides of the shoe plate 1. The elastic binding bands 2 are made of elastic fabric or rubber bands and have a certain elasticity, which can fix the patient's foot on the shoe plate 1 to prevent the patient's foot from moving. One end of the shoe plate 1 is fixed with a toe plate 3 by means of screws or welding. A plurality of sliding grooves 4 are provided on the top of the toe plate 3, and a plurality of pin grooves 5 are provided on the bottom inner wall of the sliding grooves 4. The pin grooves 5 are circular through-hole structures.

[0051] Refer to Figure 3 , a bottom plate 30 is slidably fitted in one of the sliding grooves 4. A plurality of third fixed rods 32 are fixed on the top of the bottom plate 30 by means of screws or welding. The tops of the third fixed rods 32 all extend above the bottom plate 30. The outer walls of the plurality of third fixed rods 32 are slidably sleeved with the same fixed cushion plate 6. The bottom inner wall of the fixed cushion plate 6 is in contact with the outer walls of the third fixed rods 32, and the fixed cushion plate 6 can slide on the third fixed rods 32. A fixed ring 9 is provided on the top of the fixed cushion plate 6. The fixed ring 9 is of an annular structure, and its inner diameter is slightly larger than the diameter of the fractured toe, so that the fractured toe can be sleeved into the fixed ring 9.

[0052] Refer toFigure 3 and Figure 4 At the top of the fixing ring 9, a connection box 17 is fixed by screws or welding. The connection box 17 is in the shape of a rectangular box. Inside the fixing ring 9, there are two arc-shaped clamping plates 11. Anti-slip pads are provided on the inner walls of the two arc-shaped clamping plates 11, which can increase the friction between the arc-shaped clamping plates 11 and the toes and prevent the toes from slipping. The two arc-shaped clamping plates 11 approach each other to clamp and fix the toes.

[0053] Referring to Figures 3 - 7 , the fixing structure includes a cavity 10 arranged inside the fixing ring 9. The cavity 10 is in a ring shape, and the connection box 17 communicates with the cavity 10. On the side where the two arc-shaped clamping plates 11 are away from each other, a plurality of first fixing rods 14 are fixed by screws or welding. The first fixing rods 14 are in a cylindrical structure. A fixing cylinder 13 is slidably sleeved on the outer walls of the plurality of first fixing rods 14. The fixing cylinder 13 is in a cylindrical tube structure, and the bottom of the fixing cylinder 13 is fixedly connected to the inner wall of the fixing ring 9 by screws or welding. The fixing cylinder 13 and the first fixing rod 14 cooperate to control the stable movement of the arc-shaped clamping plate 11. On the inner walls of the two sides of the fixing ring 9 that are away from each other, connection cylinders 15 are fixed by screws or welding. The connection cylinders 15 are in a cylindrical tube structure. A piston rod 16 is hermetically slidably connected inside each of the two connection cylinders 15. The piston rod 16 is in a cylindrical structure, and the outer wall of the piston rod 16 fits against the inner wall of the connection cylinder 15. One end of the two piston rods 16 that approaches each other is fixedly connected to the two arc-shaped clamping plates 11 by screws or welding. The two connection cylinders 15 are both communicated with the cavity 10. The gas in the cavity 10 is injected into the connection cylinder 15 to drive the arc-shaped clamping plate 11 to move for fixing and clamping the toes.

[0054] Referring to Figure 5 and Figure 6 , a first piston plate 18 is hermetically slidably connected inside the connection box 17, and the outer wall of the first piston plate 18 fits against the inner wall of the connection box 17. At the top of the first piston plate 18, a second fixing rod 19 is fixed by screws or welding. The second fixing rod 19 is in a cylindrical structure. The top end of the second fixing rod 19 slidably extends above the connection box 17 and is fixedly connected to a top plate 20 by screws or welding. A threaded rod 21 that is threadedly connected to the top plate 20 is rotatably connected to the top of the connection box 17. The threaded rod 21 is in a cylindrical structure, and the top end of the threaded rod 21 extends above the connection box 17 and is fixed with a rotating handle for driving the threaded rod 21 to rotate.

[0055] Specifically, by rotating the handle to drive the threaded rod 21 to rotate, the threaded rod 21 drives the top plate 20, the second fixed rod 19 and the first piston plate 18 to move downward as a whole, pressing the gas in the connection box 17 into the cavity 10. As the pressure of the gas in the cavity 10 increases, it pushes the piston rod 16 and the arc-shaped clamping plate 11 to move towards the middle, and thus the toes can be fixed by the arc-shaped clamping plate 11.

[0056] Referring to Figure 8 and Figure 9 , the positioning structure includes a first air cavity 28 arranged in the bottom plate 30, and the first air cavity 28 is a rectangular cavity structure. A second piston plate 29 is hermetically and slidably connected in the first air cavity 28. The second piston plate 29 is a rectangular plate structure, and the outer wall of the second piston plate 29 fits with the inner wall of the first air cavity 28. A plurality of second pin columns 31 are fixed to the bottom of the second piston plate 29 by screws or welding. The second pin columns 31 are cylindrical structures, and the bottom ends of the plurality of second pin columns 31 all slide and extend below the bottom plate 30 and cooperate with the pin slots 5 in the adjacent sliding grooves 4 for positioning the bottom plate 30. A gas guide pipe 27 communicating with the cavity 10 is fixed to the bottom of the fixing ring 9. The gas guide pipe 27 is a flexible pipe. The bottom end of the gas guide pipe 27 is fixedly extended into the first air cavity 28, and the bottom end of the gas guide pipe 27 is located above the second piston plate 29 for injecting the gas in the cavity 10 into the first air cavity 28 to control the second pin column 31 to move downward.

[0057] Specifically, after the arc-shaped clamping plate 11 clamps and fixes the toes, the remaining gas in the cavity 10 is injected into the first air cavity 28 through the gas guide pipe 27, and pushes the second piston plate 29 and the second pin column 31 to move downward and insert into the pin slot 5. Therefore, the toe plate 3 is positioned with the bottom plate 30 and the fixing cushion plate 6, avoiding the fixing cushion plate 6 and the fixing ring 9 from moving after the toes are fixed and causing secondary injury to the toes.

[0058] Referring to Figure 4 and Figure 8 , the adjustment structure includes two fixed seats 7 fixedly installed on the top of the fixing cushion plate 6, and these two fixed seats 7 are respectively located on both sides of the fixing ring 9. Circular rings 8 are respectively fixed on both sides of the fixing ring 9, and the circular rings 8 are slidably connected with the adjacent fixed seats 7, so that the fixing ring 9 can rotate more smoothly. An arc-shaped rack 33 is fixedly installed at the bottom of the fixing ring 9. A damping rotating shaft 35 is rotatably connected in the fixing cushion plate 6, and one end of the damping rotating shaft 35 rotates and extends to one side of the fixing cushion plate 6 for convenient manual rotation. A gear 34 is fixedly sleeved on the outer wall of the damping rotating shaft 35, and this gear 34 meshes with the arc-shaped rack 33.

[0059] Specifically, when the turned-out toes need to be reset, the damping shaft 35 can be manually rotated, and the damping shaft 35 drives the gear 34 to rotate, and the gear 34 cooperates with the arc-shaped rack 33 to drive the fixed ring 9 to rotate, thereby achieving the reset effect. Since there is damping between the damping shaft 35 and the fixed pad 6, when the damping shaft 35 rotates, it can play a positioning role for the fixed ring 9, preventing the fixed ring 9 from resetting and rotating in the opposite direction due to external factors.

[0060] Reference Figures 5 - 7 The medicine coating structure includes a lifting plate 23 that is slidably connected in the connection box 17, and the lifting plate 23 is slidably sleeved on the outer wall of the second fixed rod 19. A plurality of vertical rods 22 are fixed on the top of the lifting plate 23, and the tops of these vertical rods 22 are slidably extended to the top of the connection box 17, and a dial plate 24 is fixed together, and the dial plate 24 is also sleeved on the outer wall of the second fixed rod 19. At the top of the connection box 17, there is a medicine injection port for injecting liquid medicine. Both sides of the connection box 17 are fixedly connected with a medicine guiding hose 25. When it is necessary to apply liquid medicine to the swelling and pain parts outside, the corresponding liquid medicine can be injected through the medicine injection port on the top of the connection box 17. Then, by moving the dial plate 24 upward, the dial plate 24 will drive the lifting plate 23 upward through the vertical rod 22, and the upward movement of the lifting plate 23 will drive the liquid medicine in the connection box 17 to move upward, and discharge it to the outside through the medicine guiding hose 25. The bottom ends of the two medicine-conducting hoses 25 are fixedly passed through the fixing ring 9, and the tops of the two arc-shaped splints 11 are provided with through holes 26, and the bottom ends of the two medicine-conducting hoses 25 are fixedly extended into the through holes 26. The two arc-shaped splints 11 are provided with cotton pads 12 on the sides close to each other. When the medicine liquid enters the through holes 26 through the medicine-conducting hoses 25, it will soak the cotton pads 12 through the through holes 26, so that the medicine liquid is applied to the toes, which helps to promote blood circulation, remove blood stasis, reduce swelling and relieve pain in the toes.

[0061] Reference Figure 2 and Figure 10 A first push rod 38 is slidably inserted into the toe pad 36, and the bottom end of the first push rod 38 is plugged into the pin groove 5 to position the toe pad 36. A push plate 40 is fixed to the top of the first push rod 38, and a first spring 39 is sleeved on the outer wall of the first push rod 38. The first spring 39 is fixedly connected to the bottom of the push plate 40, and the first spring 39 is also fixed to the top of the toe pad 36.

[0062] When in use, the corresponding toe pad 36 can be slidably inserted into the sliding groove 4, and the remaining intact toes of the foot can be just placed on the push plate 40. In addition, the intact toes can also complete the insertion of the first push rod 38 and the pin groove 5 by pressing the push plate 40, which helps the movement of the intact toes after the foot is fixed, thereby promoting blood circulation in the foot.

[0063] Reference Figure 10 As shown in Figure 10 , the top of the toe pad 36 is specially designed with a relief groove 37. The main function of this relief groove 37 is to accommodate the push plate 40. When it is necessary to fix or adjust the toe, the push plate 40 can be pushed downward so that the toe can be placed flat on the top of the toe pad 36, thus bringing a more comfortable feeling to the toe and avoiding discomfort caused by improper fixation.

[0064] Embodiment 2: Refer to Figure 11 and Figure 12 On the basis of Embodiment 1, an improvement is made: a second air chamber 41 is provided inside the toe plate 3, and this second air chamber 41 is located below the sliding groove 4. Inside the second air chamber 41, a plurality of guide rods 42 are fixed, and the same third piston plate 43 is slidably sleeved on the outer walls of these guide rods 42. The third piston plate 43 forms a sealed sliding connection with the second air chamber 41. On the top of the third piston plate 43, multiple groups of support members are fixed, and the tops of these support members all slidably extend to the top of the toe plate 3. Specifically, each group of support members consists of two second push rods 44, and these two second push rods 44 are respectively located on both sides of the adjacent sliding groove 4. Such a design enables the fixed pad 6 to be pushed upward when the second push rod 44 rises, so as to perform appropriate rehabilitation training on the fractured toe. It should be noted that the distance between the two second push rods 44 is specially designed to be greater than the width of the toe pad 36, in order to avoid touching the toe pad 36 when the second push rod 44 pushes the fixed pad 6 upward, causing unnecessary interference or damage.

[0065] Refer to Figure 11 As shown in Figure 11 , in order to realize the rising movement of the second push rod 44, a clever pneumatic system is designed. A circular groove 45 is provided at the top of the shoe plate 1 on the side far from the toe plate 3, and an L-shaped pipe 52 is fixed inside the shoe plate 1. The top end of the L-shaped pipe 52 is fixedly extended into the circular groove 45, and the end far from the circular groove 45 is fixedly extended into the second air chamber 41, and the connection position with the second air chamber 41 is located below the third piston plate 43. In this way, when the air in the circular groove 45 is injected into the second air chamber 41 through the L-shaped pipe 52, the third piston plate 43 and the second push rod 44 can be pushed upward.

[0066] Refer to Figure 11, a plurality of round rods 46 are fixed on the inner wall of the bottom of the round groove 45, and a round plate 48 is slidably connected to the outer walls of these round rods 46. The round plate 48 slidably seals within the round groove 45, and a plurality of second springs 47 are fixed between its bottom and the inner wall of the bottom of the round groove 45. These second springs 47 are sleeved on the outer walls of the corresponding round rods 46 and cooperate with the round plate 48 to achieve up and down movement. When the round plate 48 descends, it can squeeze the air within the round groove 45, causing it to enter the second air chamber 41 through the L-shaped pipe 52. To increase the comfort of the patient's heel, a plurality of semi-circular rubber balls 49 are also fixed on the top of the round plate 48.

[0067] Reference Figure 11 , in addition, a limiting rod 50 is slidably and sealingly connected to the inner wall of one side of the round groove 45. The limiting rod 50 is located below the round plate 48 and is used to limit the round plate 48. One end of the limiting rod 50 slidably extends to one side of the shoe plate 1, and external threads are provided on its outer wall. A nut 51 is rotatably connected to one side of the shoe plate 1, and the nut 51 is threadedly connected to the limiting rod 50 through the external threads. By rotating the nut 51, the movement of the limiting rod 50 can be controlled, and thus the limitation of the round plate 48 can be controlled. When it is necessary to release the round plate 48, only need to rotate the nut 51, drive the limiting rod 50 to move outward through the threads on the outer wall of the limiting rod 50, so that it moves out from the bottom of the round plate 48, thereby releasing the braking of the round plate 48. In this way, the lifting of the round plate 48 can be controlled, and the air within the round groove 45 can be squeezed into the second air chamber 41, realizing the upward movement of the second push rod 44 and the fixed cushion plate 6, and performing rehabilitation activities on the fractured toe.

[0068] A usage method of a multi-dimensional adjustable fracture fixator includes the following steps:

[0069] S1. The patient steps on the shoe plate 1, fixes the shoe plate 1 on the foot through the elastic restraint band 2, slides the bottom plate 30 into the corresponding sliding groove 4, and during the sliding process, sets the fixing ring 9 on the toe to be fixed. When it is necessary to fix the toe within the fixing ring 9, drive the threaded rod 21 to rotate. The threaded rod 21 drives the top plate 20, the second fixing rod 19, and the first piston plate 18 to move downward as a whole, pressing the gas within the connection box 17 into the cavity 10. As the pressure of the gas within the cavity 10 increases, it pushes the piston rod 16 and the arc-shaped clamping plate 11 to move towards the middle, and thus the fixation of the toe can be completed through the arc-shaped clamping plate 11; in addition, the gas within the cavity 10 is injected into the first air chamber 28 through the air guide pipe 27, and pushes the second piston plate 29 and the second pin 31 to move downward and insert into the pin slot 5, thereby positioning the toe plate 3 with the bottom plate 30 and the fixed cushion plate 6, avoiding the movement of the fixed cushion plate 6 and the fixing ring 9 after the toe is fixed, which may cause secondary injury to the toe;

[0070] S2. When it is necessary to reset the toes that are turned outwards, rotate the damping rotating shaft 35 to drive the gear 34 to rotate. The gear 34 cooperates with the arc-shaped rack 33 to drive the fixed ring 9 to rotate, so as to be able to reset the toes that are turned outwards. In addition, when it is necessary to apply liquid medicine to the swollen and painful parts, inject the corresponding liquid medicine through the medicine injection port at the top of the connection box 17. Then, move the dial plate 24 upwards. The dial plate 24 drives the lifting plate 23 to move upwards through the vertical rod 22. The lifting plate 23 drives the liquid medicine to move upwards and injects it into the through hole 26 through the medicine guiding hose 25. Then, the liquid medicine wets the cotton layer pad 12 through the through hole 26, so as to apply the liquid medicine to the toes, which helps promote blood circulation and remove blood stasis, reduce swelling and relieve pain of the toes.

[0071] S3. After fixing the fractured toes, slide the corresponding toe pads 36 into the sliding grooves 4. The remaining intact toes can just be placed on the push plate 40. In addition, the intact toes can complete the insertion of the first push rod 38 into the pin slot 5 by pressing the push plate 40, which helps the intact toes move after the foot is fixed and promotes blood circulation in the foot.

[0072] S4. When the fractured toes need to be rehabilitated to a certain extent, rotate the nut 51. Drive the limit rod 50 to move outwards through the thread on the outer wall of the limit rod 50. The limit rod 50 moves out from the bottom of the circular plate 48, releasing the braking on the circular plate 48. Then the patient presses the circular plate 48 downwards with the heel. The circular plate 48 injects the air in the circular groove 45 into the second air chamber 41 through the L-shaped pipe 52 and pushes the third piston plate 43 and the second push rod 44 upwards. The corresponding second push rod 44 can push the fixed backing plate 6 and the fixed ring 9 upwards for rehabilitating the fractured toes.
