Description
Technical Field
The invention relates to the field of leg treatment, in particular to a shank fixing device for a puncture operation.
Background
The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella, is the most complex joint of the human body and belongs to a pulley joint; if the knee joint is stiff and aged, the return blood stagnates near the knee joint, and normal blood circulation is affected. In severe cases, fluid accumulation occurs in the knee joint, and puncture treatment is required.
The existing knee joint aspiration biopsy has the following three problems: firstly, the patient does not clearly define the accurate puncture body position, so that a doctor spends a great deal of time guiding the body position of the patient to be placed, and the patient often cannot accurately place the optimal body position according to the guidance of the doctor; secondly, the patient can not be fixed to the current treatment couch, and in the process of puncturing, the patient can not maintain a proper body position due to stimulation or fatigue, so that repeated guidance and body position readjustment are needed in the process of puncturing.
The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella, is the most complex joint of the human body and belongs to a pulley joint; the lower joint surface of the tibia and the inner and outer ankle joint surfaces jointly form a portal-shaped joint socket which accommodates the talus pulley, and if the knee joint or the ankle joint is stiff and aged, the return blood stagnates near the knee joint or the ankle joint, so that normal blood circulation is affected.
