Description

Skin traction device for lower limb fracture

Technical Field

The utility model belongs to the technical field of orthopedics medical machine, concretely relates to skin draw gear for low limbs fracture.

Background

The lower limb fracture mainly includes fracture around the knee joint, thigh root fracture, ankle fracture etc. and the operation treatment is the treatment means that current lower limb fracture is commonly used, and this section time before the operation after the patient is injured needs perfect each item preoperative examination, and the limbs of swelling need carry out the detumescence, and this stage suffers from the limb and need brake temporarily, and its purpose is: 1. relieve pain in the patient, and 2, is beneficial to the resolution of swelling. Common limb immobilization approaches include: plaster, brace, skin traction, and bone traction, etc. Plaster and braces need to wrap and cross fracture parts, and have the defects that the local skin and swelling condition is difficult to observe, the fracture end is difficult to adjust after being displaced, the local skin soft tissue is blocked and pressed, the air permeability is poor, and the like. The bone traction is an invasive operation, a hole needs to be drilled on a bone and a steel needle needs to be installed for traction, skin traction is used as a limb temporary braking method commonly used before an operation, the defects do not exist, a force along a long axis of a limb is applied to a fracture end by utilizing gravity at the far end of the limb far away from the fracture end without passing through the fracture end, and the fracture end generates certain tension to achieve the effect of indirectly stabilizing the fracture end.

The common lower limb skin traction device is a cotton cloth sleeve (ankle sleeve) which is annularly wrapped at the tail end of an affected limb and clamped at the front side of an ankle joint and the near end part of a heel, the far end of the ankle sleeve is provided with an annular buckle to be connected with a thin rope, a heavy hammer is hung at the tail end of the thin rope through a pulley, and the affected limb is dragged by the gravity of the heavy hammer to achieve the purpose of temporarily braking the affected limb. Traditional skin draw gear is little with ankle portion skin area of contact, and ankle joint front side and heel position are protruding often as the atress position, easily cause local skin soft tissue card to press and influence the blood circulation, and light then skin is reddened, and heavy then part or even full layer skin necrosis forms presses the sore, and secondly because of suffering the limb and can not moving about, the action of gravity of heel portion self contacts for a long time with the bed surface, oppresses and also can cause skin damage. And the ankle sleeve has poor air permeability and can also aggravate local skin injury.
