Abstract
Description
Technical Field
[0001] This invention relates to the field of medical assistive technology, and more specifically, to a combined three-dimensional traction fixation frame for the ankle joint. Background Technology
[0002] The ankle joint is one of the most easily injured joints in the human body, especially in daily life, where it is easy to twist the ankle. Ankle external fixation is a common surgical treatment for ankle fractures and dislocations. It can fix the ankle joint, keep it in the correct position, and promote fracture healing. Doctors will adjust the position and angle of the fixation according to the patient's specific condition to achieve the best treatment effect. At the same time, doctors will also observe whether the patient's foot is swollen or the skin is red and swollen, so as to detect and deal with problems in a timely manner.
[0003] According to Chinese Patent No. CN202146352U, it uses three Kirschner wires locked with locking pin screws or locking pin screws to fix the calcaneus, tibia, and metatarsals in three dimensions to a horseshoe-shaped ring and four carbon fiber connecting rods. It also uses one or more pins locked with locking pin screws to fix the medial and lateral malleoli of the ankle bones. The overall structure is compact and stable, easy to use and disassemble, and has low operating costs. It provides reliable fixation for the ankle joint and fracture fragments, and does not require surgical stripping of the periosteum, which is beneficial to the healing of ankle joint injuries.
[0004] However, when implementing the above solution, since the diameters of the medial and lateral malleoli of a person's ankle joint are different, it is not suitable for different groups of people. Furthermore, wearing the fixation frame for a long time, because it is placed on the patient's skin surface, can easily cause muscle pressure and block blood flow, leading to numbness in the foot and hindering the patient's recovery. Therefore, we propose a combined three-dimensional traction fixation frame for the ankle joint. Summary of the Invention
[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a combined three-dimensional traction fixation frame for the ankle joint. An ankle joint clamping block is held in place by a positioning clip and a glued ring frame via an insert rod. This causes the ankle joint clamping block to deflect along the surface of the glued ring frame, resulting in two sets of ankle joint clamping blocks wrapping around the ankle positioning area. The patient's sole rests on a foot support plate. Simultaneously, a rope is inserted through a rope binding hole at one end and tied to the rope binding hole at the other end, ensuring the ankle joint clamping block is tightly bound to the surface of the ankle, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined three-dimensional traction fixation frame for the ankle joint, comprising a knee positioning clamp, wherein an insertable hollow rubber ring with an internal cavity is fixedly connected inside the knee positioning clamp, the insertable hollow rubber ring using silicone material to position the patient's knee joint, a cylindrical flow frame is fixedly connected to one end of the insertable hollow rubber ring, and an airflow conduit is fixedly connected to one end of the insertable hollow rubber ring, wherein the connection between the airflow conduit and the insertable hollow rubber ring, and the connection between the airflow conduit and the cylindrical flow frame are sealed, and the connection between the airflow conduit and the insertable hollow rubber ring, and the connection between the airflow conduit and the cylindrical flow frame are filled with rubber, resulting in good sealing performance of the pipe assembly connection;
[0007] The bottom end of the cylindrical transfer frame is fixedly connected to a communicating positioning elongated rod. The bottom end of the positioning elongated rod is fixedly connected to a communicating hollow connecting ring. Foot surface positioning ring blocks are hinged to both ends of the hollow connecting ring. These foot surface positioning ring blocks can deflect along the horizontal plane of the hollow connecting ring. Multiple sets of foot surface positioning ring blocks wrap around the muscle surface of the patient's calf below the knee along the horizontal plane of the hollow connecting ring for positioning. One end of the positioning elongated rod, passing through the hollow connecting ring, is fixedly connected to a foot end clamping block. The patient's heel rests against the surface of the foot end clamping block, providing support and reducing the burden on the patient when walking. Due to the pressure of walking caused by the injury to the heel, the two ends of the foot clamping block are fixedly connected to the insertion rod. One end of the insertion rod is fixedly connected to the positioning clamping frame, and one end of the positioning clamping frame is fixedly connected to the adhesive ring frame. One end of the adhesive ring frame is hinged to the ankle joint clamping block. There are two sets of ankle joint clamping blocks. The area between the two sets of ankle joint clamping blocks is the ankle positioning area. The insertion rod clamps the ankle joint clamping block with the positioning clamping frame and the adhesive ring frame, causing the ankle joint clamping block to deflect along the surface of the adhesive ring frame. This causes the two sets of ankle joint clamping blocks to wrap around the ankle positioning area, while the patient's sole is placed on the foot support plate.
[0008] The bottom end of the foot clamping block is hinged to a foot support plate, and one end of the ankle clamping block has two sets of rope binding holes.
[0009] In a preferred embodiment, rubber pressure ring blocks are fixedly connected to both ends of the inserting hollow rubber ring, a single-sided clamping frame is attached to the end of the rubber pressure ring block away from the inserting hollow rubber ring, positioning screw blocks are fixedly connected to both ends of the single-sided clamping frame, a screw rod frame is inserted into the end of the positioning screw block away from the inserting hollow rubber ring, and a nut is threadedly connected to the outer surface of the screw rod frame.
[0010] In a preferred embodiment, the end of the insertable hollow rubber ring facing the rubber pressure ring block is fixedly connected to multiple sets of rubber clamps arranged in a ring shape inside the insertable hollow rubber ring. The inner wall of the insertable hollow rubber ring is fixedly connected to a stretchable ring band, which is compressed inside the insertable hollow rubber ring. When the patient walks or exercises, the muscles expand, and the muscles at the skin expand and compress the inner wall of the insertable hollow rubber ring. The insertionable hollow rubber ring is compressed, causing the multiple sets of rubber clamps to compress inside the insertable hollow rubber ring. At the same time, the stretchable ring band inside the insertable hollow rubber ring can be compressed by lubrication, so as to avoid the patient's skin being positioned too tightly, and thus avoiding excessive back pressure on the surface of the positioning component, which would cause pain.
[0011] In a preferred embodiment, a fixed long rod is fixedly connected to one end of the single-sided clamping frame facing the cylindrical flow frame, and a first conductive air tube is slidably connected to the outer surface of the fixed long rod. A hollow conical frame is fixedly connected to one end of the first conductive air tube, and the fixed long rod is slidably arranged in a sealed state within the first conductive air tube.
[0012] In a preferred embodiment, a pusher block is fixedly connected to the outer surface of the fixed long rod and closely attached to the inner wall of the hollow conical frame. Multiple sets of guide springs arranged in a ring are fixedly connected to the outer surface of the pusher block, and the multiple sets of guide springs are fixedly installed on the inner wall of the hollow conical frame.
[0013] In a preferred embodiment, the second conductive air tube is connected to the cylindrical flow frame, and the cylindrical flow frame, the positioning elongated rod, the hollow connecting ring, and the foot surface positioning ring block are connected in an airflow communication state. The foot surface positioning ring block has a positioning cavity inside, which improves the airflow communication sealing.
[0014] In a preferred embodiment, a semi-circular clamping block is fixedly connected to one end of the positioning cavity. There are multiple sets of semi-circular clamping blocks, and clamping rods are fixedly connected inside the multiple sets of semi-circular clamping blocks. A rope clamping block is fixedly connected to one end of the foot surface positioning ring block, and a positioning strap is fixedly connected to one end of the rope clamping block. A small ring hole frame is fixedly connected to one end of the positioning ring block on the foot surface. Airflow is transmitted to fill the positioning cavity, and the strap moves from the rope clamping block to the small ring hole frame, thereby completing the binding of the patient's lower leg.
[0015] The technical effects and advantages of this invention are as follows:
[0016] 1. The insertion rod uses a positioning clamp and a glued ring frame to hold the ankle joint clamping block, causing the ankle joint clamping block to deflect along the surface of the glued ring frame. This causes two sets of ankle joint clamping blocks to wrap around the ankle positioning area, while the patient's sole is placed on the foot support plate. At the same time, a rope is inserted through the rope binding hole at one end and tied to the rope binding hole at the other end. This allows the ankle joint clamping block to be tightly bound to the surface of the ankle, thereby improving the synchronous positioning effect of the ankle joint and facilitating synchronous fixation of multiple ankle joints and joints.
[0017] 2. The patient inserts their knee into the hollow rubber ring. The hollow rubber ring is an inflatable structure and can be inflated through the air holes on its surface. Initially, the diameter of the central hole in the hollow rubber ring is larger than the outer diameter of the patient's knee and the longest diameter of the patient's foot, making it easier for the patient to insert the ring without using the ankle joint. Then, the doctor uses a rotating screw frame, which presses the single-sided clamp and rubber pressure ring block against the outer surface of the hollow rubber ring along the inner cavity of the positioning screw block. This causes the inner wall of the hollow rubber ring to fit as close as possible to the patient's knee surface. The screw frame is then positioned using a nut, thus facilitating the positioning of different patients' knees and saving on the cost of ankle joint fixation.
[0018] 3. When the hollow rubber ring is compressed, the internal airflow is transmitted to the cylindrical transmission frame through the airflow conduit. Simultaneously, due to the expansion of the patient's muscles, the single-sided clamp moves outward, and the single-sided clamp drives the fixed long rod to slide outward inside the first transmission air tube and the hollow conical frame. This causes the pushing disc to move towards the first transmission air tube within the hollow conical frame, causing the air inside the positioning long rod to expand outward. The positioning ring on the foot surface can fully compress the patient's lower leg due to the airflow transmitted by the positioning long rod and the hollow connecting ring, giving the patient a slight squeezing sensation in the ankle joint. When the pushing disc returns to its original position through the elasticity of multiple sets of guide springs, the airflow inside the hollow conical frame returns to its original state, thus producing a squeezing and massaging sensation on the ankle joint mechanism, thereby improving the recovery of the ankle joint muscles and helping the patient recover.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Refer to the instruction manual appendix Figure 1-3 An embodiment of the present invention provides a combined three-dimensional traction fixation frame for the ankle joint, comprising a knee positioning clamp 1. An insertable hollow rubber ring 2 with an internal cavity is fixedly connected inside the knee positioning clamp 1. The insertable hollow rubber ring 2 uses silicone material to position the patient's knee joint. A cylindrical flow frame 22 is fixedly connected to one end of the insertable hollow rubber ring 2, and an airflow conduit 21 is fixedly connected to the other end of the insertable hollow rubber ring 2. The connections between the airflow conduit 21 and the insertable hollow rubber ring 2, and between the airflow conduit 21 and the cylindrical flow frame 22, are sealed. Rubber is filled at the connections between the airflow conduit 21 and the insertable hollow rubber ring 2, and between the airflow conduit 21 and the cylindrical flow frame 22, resulting in good sealing of the pipe assembly connections.
[0029] A cylindrical transfer frame 22 has a fixedly connected long positioning rod 5 at its bottom end, and a fixedly connected hollow connecting ring 7 at its bottom end. Foot surface positioning ring blocks 6 are hinged to both ends of the hollow connecting ring 7. The foot surface positioning ring blocks 6 can deflect along the horizontal plane of the hollow connecting ring 7. Multiple sets of foot surface positioning ring blocks 6 wrap around the muscle surface of the patient's calf below the knee along the horizontal plane of the hollow connecting ring 7 for positioning. A foot end clamping block 10 is fixedly connected to one end of the long positioning rod 5 that passes through the hollow connecting ring 7. The patient's heel rests against the surface of the foot end clamping block 10, providing support when the patient walks and reducing pain in the patient's heel due to injury. The pressure of walking is reduced. The two ends of the foot clamping block 10 are fixedly connected to the insertion rod 14. One end of the insertion rod 14 is fixedly connected to the positioning clamping frame 16. One end of the positioning clamping frame 16 is fixedly connected to the adhesive ring frame 15. One end of the adhesive ring frame 15 is hinged to the ankle joint clamping block 17. There are two sets of ankle joint clamping blocks 17. The area between the two sets of ankle joint clamping blocks 17 is the ankle positioning area. The insertion rod 14 clamps the ankle joint clamping block 17 with the positioning clamping frame 16 and the adhesive ring frame 15, causing the ankle joint clamping block 17 to deflect along the surface of the adhesive ring frame 15, so that the two sets of ankle joint clamping blocks 17 wrap around the ankle positioning area, while the patient's sole is on the foot support plate 18.
[0030] The bottom end of the foot clamping block 10 is hinged to the foot support plate 18. One end of the ankle clamping block 17 has two sets of rope binding holes. By inserting a rope into one end of the rope binding hole and tying the rope to the other end of the rope binding hole, the ankle clamping block 17 can be tightly bound to the surface of the ankle, thereby improving the synchronous positioning effect of the ankle joint and facilitating synchronous fixation of multiple ankle joints.
[0031] Refer to the instruction manual appendix Figure 4-6Rubber pressure ring blocks 3 are fixedly connected to both ends of the insertable hollow rubber ring 2. A single-sided clamping frame 4 is attached to the end of the rubber pressure ring block 3 away from the insertable hollow rubber ring 2. Positioning screw blocks 19 are fixedly connected to both ends of the single-sided clamping frame 4. A screw rod frame 20 is inserted into the end of the positioning screw block 19 away from the insertable hollow rubber ring 2. A nut is threaded onto the outer surface of the screw rod frame 20. The patient inserts his knee into the insertable hollow rubber ring 2. The insertable hollow rubber ring 2 is an inflatable structure and can be inflated through the inflation holes on the surface of the insertable hollow rubber ring 2. The insertable hollow rubber ring 2 begins to... The diameter of the central hole is larger than the outer diameter of the patient's knee and the longest diameter of the patient's foot, making it easy for the patient to insert the insertion rubber hollow ring 2 without using the ankle joint. Then, the doctor uses the rotating screw frame 20, which presses the single-sided clamping frame 4 and the rubber pressure ring block 3 against the outer surface of the insertion rubber hollow ring 2 along the inner cavity of the positioning screw block 19. This causes the inner wall of the insertion rubber hollow ring 2 to fit as close as possible to the surface of the patient's knee. The screw frame 20 is positioned using a nut, thus achieving convenient positioning for different patients' knees and saving the cost of ankle joint fixation.
[0032] Refer to the instruction manual appendix Figure 5-6 The hollow rubber ring 2 is fixedly connected to one end of the rubber pressure ring block 3 with multiple sets of rubber clamps 24 arranged in a ring shape inside the hollow rubber ring 2. A stretchable ring band 25 is fixedly connected to the inner wall of the hollow rubber ring 2. The stretchable ring band 25 is in a compressed state inside the hollow rubber ring 2. When the patient walks or exercises, the muscles expand, and the expanded muscles at the skin compress the inner wall of the hollow rubber ring 2. The compression of the hollow rubber ring 2 causes the multiple sets of rubber clamps 24 to engage with the rubber... The hollow ring 2 is compressed inside, and the stretchable ring 25 inside the hollow rubber ring 2 can be compressed by oiling, so as to avoid the patient's skin being positioned too tightly and causing pain due to excessive counter pressure on the surface of the positioning component. One end of the single-sided clamp 4 facing the cylindrical flow frame 22 is fixedly connected to a fixed long rod 27. The outer surface of the fixed long rod 27 is slidably connected to a first conduction air tube 26. One end of the first conduction air tube 26 is fixedly connected to a hollow conical frame 23. The fixed long rod 27 is slidably set in a sealed state inside the first conduction air tube 26.
[0033] Furthermore, a pusher plate 29 is fixedly connected to the outer surface of the fixed long rod 27, which is closely attached to the inner wall of the hollow conical frame 23. Multiple sets of guide springs 28 arranged in a ring are fixedly connected to the outer surface of the pusher plate 29. These guide springs 28 are fixedly installed on the inner wall of the hollow conical frame 23. When the inserted hollow rubber ring 2 is compressed, the internal airflow is transmitted through the airflow conduit 21 to the cylindrical airflow frame 22. Simultaneously, due to the expansion of the patient's muscles, the single-sided clamp 4 moves outward, causing the fixed long rod 27 to slide outward within the first airflow conduit 26 and the hollow conical frame 23. This causes the pusher plate 29 to move towards the first airflow conduit 26 within the hollow conical frame 23. The movement causes the air inside the positioning rod 5 to expand outward. Due to the airflow transmitted by the positioning rod 5 and the hollow connecting ring 7, the positioning ring 6 on the foot surface can fully compress the patient's lower leg, causing the patient to experience a slight squeezing sensation in the ankle joint. This prevents the fixation frame from falling off during the patient's movement. At the same time, when the patient's muscles move, the pushing disc 29 returns to its original position through the elasticity of multiple sets of guide springs 28. When the airflow inside the hollow conical frame 23 returns to its original state, the airflow inside the positioning ring 6 on the foot surface also returns to its original position, thus creating a squeezing and massaging sensation on the ankle joint mechanism, thereby improving the recovery of the ankle joint muscles and helping the patient recover.
[0034] Refer to the instruction manual appendix Figure 7 The second air conduction tube 30 is connected to the cylindrical air conduction frame 22. The cylindrical air conduction frame 22, the positioning long rod 5, the hollow connecting ring 7, and the foot surface positioning ring block 6 are connected in an airflow communication state. The foot surface positioning ring block 6 has a positioning cavity 31 inside, which improves the airflow communication sealing. One end of the positioning cavity 31 is fixedly connected to a semi-circular clamping block 8. There are multiple sets of semi-circular clamping blocks 8. The clamping rod 9 is fixedly connected inside the multiple sets of semi-circular clamping blocks 8. One end of the foot surface positioning ring block 6 is fixedly connected to a rope clamping block 11. One end of the rope clamping block 11 is fixedly connected to a positioning strap 12. One end of the positioning strap 12 is fixedly connected to a small ring hole frame 13. The small ring hole frame 13 is fixedly installed at one end of the foot surface positioning ring block 6. The airflow is filled inside the positioning cavity 31, and the strap moves from the rope clamping block 11 to the small ring hole frame 13, thereby completing the binding of the patient's lower leg.
