Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to an adjustable brace for fixing dislocation after hip replacement surgery in orthopedics. Background Technology

[0002] Hip dislocation after total hip arthroplasty is a common complication. After manual or surgical reduction, the risk of re-dislocation increases, often requiring immobilization. Traditional immobilization methods include skin traction, T-shaped shoe with skin traction, pelvic fixator with bilateral lower limb fixators, and pelvic fixator with unilateral lower limb fixator.

[0003] The above methods have drawbacks:

[0004] 1. Skin traction: Skin traction alone is not a reliable fixation method and is prone to internal and external rotational instability. If the patient's cooperation is poor, dislocation is very likely to occur again. In addition, the operation is relatively complicated, requires a special frame, and is difficult to implement at home.

[0005] 2. T-shaped shoe + skin traction: superior to skin traction alone, but the fixation is still not reliable enough. If the patient's cooperation is poor, dislocation is still very likely to occur again. Moreover, the operation is relatively complicated, requires a special frame, and is difficult to implement at home.

[0006] 3. Pelvic fixation device + bilateral lower limb fixation device: The pelvis and both lower limbs need to be firmly fixed, which can easily cause bedsores, is not easy to care for, and causes difficulty in urination and defecation.

[0007] 4. Pelvic fixation device + unilateral lower limb fixation device: This requires the pelvis and both lower limbs to be firmly fixed, which can easily cause bedsores, is not easy to care for, and can cause difficulty in urination and defecation.

[0008] Therefore, we have made improvements to this and proposed an adjustable brace for fixing dislocations after orthopedic hip replacement surgery. Utility Model Content

[0009] The adjustable brace for fixing dislocation after orthopedic hip replacement surgery proposed in this utility model solves the problems in the background art.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] An adjustable brace for fixing dislocation after orthopedic hip replacement surgery includes a hollow connecting tube. The left end of the hollow connecting tube is detachably connected to a telescopic rod, and the right end of the hollow connecting tube is detachably connected to a rod. An ankle fixation mechanism is installed at the ends of the telescopic rod and the rod that are far apart from each other.

[0012] The ankle fixation mechanism includes a connecting side column, one end of which is fixedly installed on the other end of a telescopic rod or a member, and a C-shaped mounting plate is installed on the other end of the connecting side column. A ring-shaped positioning plate is fixedly installed on the other end of the C-shaped mounting plate.

[0013] Preferably, the right end of the telescopic rod passes through the left end of the hollow connecting tube, and the side face of the right end of the telescopic rod slides and fits against the inner wall of the hollow connecting tube in the horizontal direction. The hollow connecting tube is detachably fixed to the telescopic rod by a set screw.

[0014] Preferably, a knob is fixedly provided at the upper end of the set screw, and a scale line parallel to the horizontal direction is provided at the upper end of the telescopic rod.

[0015] Preferably, four second connecting plates are fixedly installed in a circular array at the left end of the rod, and the second connecting plates are detachably fixed to the right end of the hollow connecting pipe by second connecting bolts.

[0016] Preferably, a second magnet is embedded and fixedly installed on the lower end face of the hollow connecting tube, and a first magnet is embedded and fixedly installed on the lower end of the rod, and the first magnet and the second magnet are magnetically attracted to each other.

[0017] Preferably, two first connecting plates are symmetrically fixedly installed at one end of the connecting side column away from the C-shaped mounting plate, and the first connecting plates are detachably fixed to the other end of the telescopic rod or rod by first connecting bolts.

[0018] Preferably, a vertically arranged mounting screw is fixedly installed at the end of the C-shaped mounting plate away from the annular positioning plate, and the connecting side column is rotatably mounted on the mounting screw through a bearing. A locking nut is threadedly fitted on the mounting screw at a position above the connecting side column.

[0019] Preferably, a connecting ring is fixedly installed on the inner side of the C-shaped mounting plate away from the mounting screw, and a soft strap is fixedly connected to the other end of the annular positioning plate.

[0021] The beneficial effects of this utility model are:

[0022] 1. This type of adjustable brace for fixing dislocation after hip replacement surgery allows for adjustment of the position of the telescopic rod by loosening the top screw, thereby adjusting the distance between the two ankle fixation mechanisms. This allows for adjustment of the ankle joint distance according to the patient's specific condition. By setting the connecting side column and the mounting screw to a rotatable connection, the angle of the ankle fixation mechanism can be adjusted, thus allowing for adjustment of the internal and external rotation placement of the patient's ankle joint, resulting in better applicability.

[0023] 2. This adjustable brace for fixing dislocation after hip replacement surgery in orthopedics allows for the separation of the first connecting plate from the telescopic rod or other member by disassembling the first connecting bolt, thereby disassembling the ankle fixation mechanism. This reduces the storage volume of the invention, making it more convenient to carry and maintain. Disassembling the second connecting bolt allows for the separation of the second connecting plate from the hollow connecting tube, thus disassembling the member. The member can be attracted and fixed to the lower end of the hollow connecting tube by the adsorption properties of the first and second magnets, further reducing the storage volume of the invention and making it more convenient to carry.

[0024] 3. This type of adjustable brace for fixing dislocation after orthopedic hip replacement surgery allows the patient's two ankles to be placed inside two annular positioning plates. Then, a soft strap is wrapped around the patient's ankle and passed through the connecting ring. Finally, the Velcro hook on the soft strap is attached to the Velcro hook at the rear end of the annular positioning plate, thereby fixing the patient's ankle inside the annular positioning plate.

[0025] This invention provides a secure fixation mechanism, adjustable functionality, improved applicability, and ease of operation and maintenance, making it practical and reliable. Attached Figure Description

[0035] Example 1

[0036] Reference Figure 1 And 3-6, an adjustable brace for fixing dislocation after orthopedic hip replacement surgery, including a hollow connecting tube 1, a telescopic rod 3 detachably connected to the left end of the hollow connecting tube 1, a rod 6 detachably connected to the right end of the hollow connecting tube 1, and an ankle fixation mechanism 5 installed at the ends of the telescopic rod 3 and the rod 6 that are far apart from each other.

[0037] The ankle fixation mechanism 5 includes a connecting side column 506. One end of the connecting side column 506 is fixedly installed on the other end of the telescopic rod 3 or the rod 6. A U-shaped mounting plate 502 is installed on the other end of the connecting side column 506. An annular positioning plate 501 is fixedly installed on the other end of the U-shaped mounting plate 502. The annular positioning plate 501 has a design that is wider at the top and narrower at the bottom, which is more suitable for the human body structure.

[0038] In this embodiment, the right end of the telescopic rod 3 passes through the left end of the hollow connecting tube 1, and the right end face of the telescopic rod 3 slides and fits against the inner wall of the hollow connecting tube 1 in the horizontal direction. The hollow connecting tube 1 is detachably fixed to the telescopic rod 3 by the set screw 2.

[0039] By loosening the set screw 2, the position of the telescopic rod 3 can be adjusted, thereby adjusting the distance between the two ankle fixation mechanisms 5, and thus adjusting the ankle joint distance according to the patient's specific condition.

[0040] A knob is fixedly installed at the upper end of the set screw 2, and a scale line 4 parallel to the horizontal direction is installed at the upper end of the telescopic rod 3.

[0041] By observing the position of the scale line 4 obscured by the right end of the hollow connecting tube 1, the telescopic position of the telescopic rod 3 can be accurately detected, thereby enabling precise adjustment of the distance between the two ankle fixing mechanisms 5.

[0042] Two first connecting plates 505 are symmetrically fixed at one end of the connecting side column 506 away from the C-shaped mounting plate 502. The first connecting plates 505 are detachably fixed to the other end of the telescopic rod 3 or rod 6 by the first connecting bolts 510.

[0043] By disassembling the first connecting bolt 510, the first connecting plate 505 can be separated from the telescopic rod 3 or the rod 6, thereby completing the disassembly of the ankle fixing mechanism 5. This makes it easier to reduce the storage volume of this utility model and makes it more convenient to carry and maintain.

[0044] A vertically installed mounting screw 503 is fixedly installed on one end of the C-shaped mounting plate 502 away from the annular positioning plate 501. The connecting side column 506 is rotatably mounted on the mounting screw 503 through a bearing. A locking nut 504 is threaded onto the mounting screw 503 and located above the connecting side column 506.

[0045] By setting the connecting side column 506 and the mounting screw 503 to be rotatably connected, the angle of the ankle fixation mechanism 5 can be adjusted, thereby adjusting the internal and external rotation position of the patient's ankle joint, which is more applicable. After the adjustment is completed, tightening the locking nut 504 can position the annular positioning plate 501.

[0046] A connecting ring 507 is fixedly installed on the inner side of the C-shaped mounting plate 502 away from the mounting screw 503. A soft strap 508 is fixedly connected to the other end of the annular positioning plate 501.
