Background technique

Lower extremity fractures are a common type of injury and often require surgical treatment. During the operation, fluoroscopy and position changes are often required, and the assistance of multiple assistants is often required. In the process of surgery and fluoroscopy, in order to obtain some special fluoroscopy positions, such as the calcaneal axis position and continuous external rotation of the ankle, it is also necessary to manually support the lower limbs for fluoroscopy. At present, since there is no special surgical auxiliary device to grasp and support the patient's lower limbs, it is necessary for the operator to support the fractured lower limbs under radiation exposure. In the process of surgery and fluoroscopy, the disadvantages of artificial support are obvious. First, artificial support is not stable enough, often cannot achieve an accurate angle, and it is difficult to maintain it for a long time and repeat it many times, which is not good for the operation; In the process of completing fluoroscopy on the patient, it will also cause radiation damage to the operator. For patients, due to the limited number of exposures, the dose of radiation exposure during treatment will not cause serious harm to the human body, but for operators, because they need to perform operations all year round, the accumulation of a large amount of radiation damage is harmful to the health of the operator. A serious injury. With the development and progress of medical technology, the application of minimally invasive surgery in lower extremity fracture surgery is becoming more and more common.
