Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a tibia distraction reduction supporting system.
Background
The tibia is one of the two bones of the lower leg, is positioned at the inner side of the lower leg, plays an important role in supporting the body, and is a tibia surgical operation which is generally needed to carry out traction reduction on the affected limb for patients with fracture of the tibia and main bearing bones in the lower leg bones. At present, the hospital basically uses traction tools and instruments, such as fixed traction needles, and the working principle is that two bone traction needles are respectively fixed near the joint surface of the far and near sections of the fracture, and then the movable block is unidirectionally extruded by rotating the middle nut, so that the traction effect is achieved, but the fixed traction needles cannot be used for patients with osteoporosis. Because of point fixation, the reduction stability is poor, the broken end can not be effectively stabilized, the broken end can be overlapped or partially overlapped with the incision surface when in use, the next operation of an operator is influenced, the next working difficulty is increased, the operation time is prolonged, and meanwhile, the fracture reduced by the restorer can not be subjected to intramedullary nail operation because the traction nail is positioned at the central part of the bone, and can not be basically completed by minimally invasive operation with flexible operation space.
The traction table is mainly used for orthopedic surgery and traction in the operation, the application range is mainly fracture in the femoral range, the fracture reduction traction in the femoral fracture operation can be met, the fracture position can be adjusted by rotating inside and outside, the position required by a doctor is reached, the traction table is too large in size, too heavy in weight and incapable of high-temperature sterilization, when the traction table is used, a limb is fixed in a germ-free state, the upper part of the traction table is propped against the pubis joint part, the lower part of the traction table puts ankle joints (about 12 centimeters) and soles into shoe covers, and the shoe covers and bandages are used for fixation in the germ-free state. The affected limb is slightly pulled to hang in the air, and the big and small legs are kept on a straight line. Sterilizing the exposed part of skin, spreading sterile towel, and spreading sterile cloth. The operator can only use other personnel under the table to command and complete the position the operator wants by the operator, the work is time-consuming and labor-consuming, and the operator needs to interrupt the operation or the thinking frequently to command the assistant. The greater problem is that the traction frame can not be used basically in fracture operation of the tibia side because the ankle joint is in a germ state. The knee joint cannot bend, and the like.
