Description

An orthopedic skin traction device

Technical field

The utility model relates to medical equipment, specifically an orthopedic skin traction device.

Background technique

Skin traction is to use tape or leather sheath to wrap the patient's fracture site (such as elbow joint fracture, femoral neck fracture), and then use a traction hammer to perform traction. The traction force is indirectly applied to the bone or joint through the skin, fascia, and muscles. The principle of action force and reaction force resists the tension and retraction of soft tissues, allowing fractures and dislocations to be restored, preventing and correcting deformities. It is easy to operate, does not need to break bone tissue, causes little damage to limbs, and causes little pain to patients. Features, widely used in the treatment of limb fractures in children under twelve years old.

Existing leather traction belts usually need to be used with a Thomas frame. In order to keep the traction limb and the traction force at the same level, and in order for the heel to leave the bed, the heel is suspended to prevent skin pressure damage. However, the Thomas is inconvenient to use. Sometimes the length of the child's affected limb is inconsistent with the length of the Thomas frame. Therefore, instead of using the Thomas frame, medical staff use a towel to pad the ankle of the affected limb to raise the affected limb and put the heel in the air.

The shortcomings of the above technology are:

1. Due to the gap between the outer diameter of the patient's thigh and the outer diameter of the calf, the existing traction belt is easy to slide down, reducing the treatment effect.

2. It is difficult for the existing traction belt to completely fix the affected limb of the child, and it is easy to cause loosening.

3. If the traction belt strangles the affected limb of the child, it is easy to cause skin strangulation marks.

4. During traction, the affected limb of the child tends to sway from side to side, causing the traction force to be inconsistent and reducing the therapeutic effect.

5. Towels are prone to wrinkles and may cause damage to the skin of the child's affected limbs during traction.

6. Use a towel to pad the ankle, which may not necessarily allow the heel of the child's affected limb to hang in the air.

Utility model content
