Child thighbone adjustable lever traction support

Abstract

The invention discloses a child thighbone adjustable lever traction support, and belongs to the technical field of medical equipment. The support comprises a base, an inclined supporting frame, a thighbone angulation adjusting mechanism, a thighbone traction mechanism and a pressure regulating mechanism; the inclined supporting frame is obliquely arranged on the base, the thighbone angulation adjusting mechanism is arranged at one side of the inclined supporting frame, the thighbone traction mechanism comprises a first traction support and a second traction support, one end of the first traction support is rotationally connected with one end of the second traction support, the end, away from the second traction support, of the first traction support is slidably connected with the inclinedsupporting frame, the pressure regulating mechanism is arranged on the base and located at the side, away from the thighbone angulation adjusting mechanism, of the inclined supporting frame, and the second traction support is connected with the pressure regulating mechanism. The support is simple in structure and convenient to use, the needed traction force can be provided by adjusting the thighbone traction mechanism, the fracture angulation can be corrected, the thighbone angulation can be further regulated through the thighbone angulation adjusting mechanism, and the reset angle can be obtained.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an adjustable lever traction bracket for children's femur. Background technique [0002] Femoral shaft fractures account for about 6% of systemic fractures, and are more common in children under the age of 10. They are a common and frequently-occurring disease in children with fractures. The femur is a single bone in the thigh, rich in muscle attachment, strong and powerful, prone to shortening, displacement and angular deformity, so it needs timely treatment. The existing commonly used treatment measures mainly include the following methods: 1. splint or plaster external fixation; 2. suspension skin traction; 3. horizontal skin traction; 4. bone traction; Internal fixation; 6. Open reduction or closed reduction, elastic intramedullary nail internal fixation plus external fixation. However, there are some defects in the existing treatment measures, which a...

Problems solved by technology

[0003] 1. Splint or plaster external fixation method, external fixation with splint or plaster after reduction, existing defects: (1) poor fixation reliability, prone to fracture and redisplacement; (2) children's skin is delicate, prone to skin maceration and even Pressure sores; (3) joints are fixed, prone to joint stiffness; (4) management remains unchanged, adjusted at any time, children are not easy to tolerate, prone to unacceptable alignment relationship, and even fracture malunion

[0004] 2. Suspension skin traction method is suitable for children under the age of 3-4. There are defects: (1) The skin of children is delicate and prone to skin maceration and even pressure sores; (2) The traction force is unreliable and prone to shortening Displacement, the length of the lower limbs is unequal after the fracture heals, although the same length can basically be restored about one year after the injury, but the guardians of the child are generally not easy to accept, and there are hidden dangers of medical disputes; (4) The comfort of traction is poor, and children often cannot tolerate it for a long time

[0005] 3. The horizontal skin traction method is suitable for children aged 5-8. There are defects: (1) there is a risk of skin maceration and pressure sores; (2) it cannot match the physiological curvature of the femur, and it is prone to angular deformity. Partial splint assistance; (3) There is also insufficient traction strength, which is prone to shortening of limbs; (4) It is difficult to take pictures, and it is impossible to dynamically observe the alignment and growth of fractures; (5) The traction comfort is poor, and patients with Children often cannot tolerate it for a long time; (6) The swelling of the injured limb with horizontal traction subsides slowly

[0006] 4. Bone traction method, suitable for patients aged 8-12, has defects: (1) there is a certain trauma, and there is even a risk of damage to the epiphysis; (2) excessive traction may cause bone nonunion, and even surgical bone grafting is required; (3) It is difficult to take pictures, and it is impossible to dynamically observe the alignment and growth of fractures; (4) The comfort of traction is poor, and children often cannot tolerate it for a long time

[0007] 5. Open reduction and plate internal fixation can achieve good reduction and good fixation, and the children are comfortable and easy to manage. Existing defects: (1) There are anesthesia, infection, damage to important nerves and blood vessels, and internal fixation loosening and shifting. (2) Re-operation is required to remove the internal fixation; (3) Scars are left, which will have a certain impact on the patient's psychology or career choice; (5) At least two operations, the economic burden is high

[0008] 6. Open reduction or closed reduction, internal fixation with elastic intramedullary nail plus external fixation is a relatively new treatment plan with less trauma and can improve the alignment of fractures, but there are still the following defects: (1) Intraoperative There are many times of radiation; (2) there are risks such as anesthesia, infection, damage to important nerves and blood vessels, loosening and displacement of internal fixation; (3) reoperation is required to remove the internal fixation; Certain impact; (5) At least two surgeries, high economic burden; (6) Primary hospitals are generally low in proficiency in surgeries, and seldom carry out surgeries
