Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of bone surgery leg lifting gears.
Background technology
Orthopaedics is one of most common section office of various big hospital, main dissection, physiology and the pathology for studying skeletal musculature,
The normal morphology and function of this system are kept and developed with drug, operation and physical method.With the change in epoch and society
More, injury of orthopaedics department spectrum has apparent variation, for example, the diseases such as tuberculous osteoarthropathy, osteomyelitis, infantile paralysis significantly reduce,
Wound caused by traffic accident increases, the aging of population, and fracture, osteology arthropathy caused by senile osteoporosis increase,
The influence of environmental factor, bone tumour, rheumatoid arthritis accordingly increase etc., and since bone all hides in human body
Portion, therefore most orthopaedics problem is required for carrying out bone surgery.
Suitable operation position is most important to the success of bone surgery, and inappropriate operation position can extend surgical procedure
Time, the generation of postoperative complications is even resulted in, finally there is the possibility for inducing lawsuit.Suitable operation position includes two layers
Concept：1. the exposure and operation performed the operation are the most appropriate；2. patient does not occur because of putting for operation position at the end of surgical procedure
Corresponding complication.Due to bone surgery mostly meeting trans-articular operation, especially for the bone surgery of leg, need performing the operation
Limb lifting is exposed whole notch by assistant in journey.Since operating time is long, with regard to will appear two problems：1. when long
Between praise action, assistant's muscle power is lost bigger, is easy occur unstable state when finishing operations；2. operating doctor
Cooperation between assistant once generates deviation, and assistant quickly comprehension operating doctor cannot require, it is necessary to constantly readjust, to prolong
Accidentally operating time.
Invention content
