Technical Field
The application relates to the field of medical auxiliary appliances, in particular to an auxiliary fixing appliance for foot CT scanning.
Background
CT examination is one of the important means for diagnosing diseases, and the accuracy of the CT examination result is directly affected by the stable positioning of the scanned body. During the CT scanning of the ankle joints, the symmetry of the ankle joints at two sides of most patients is difficult to maintain in the scanning process, if the ankle joints at two sides are asymmetric, the two sides of the tissue structure of the ankle joint of the image obtained by the scanning layer are obviously asymmetric, the comparison at two sides cannot be carried out, great trouble is brought to the diagnosis work of a diagnosis doctor of an image department, and particularly for patients with congenital variation, the correctness of the judgment of the final result of the doctor of the image department can be directly influenced. Resulting in missed diagnosis, misdiagnosis and even no diagnosis at all, thereby directly influencing the correct development of the next diagnosis and treatment work of the patient.
To overcome the above situation, 2 methods are currently adopted to solve the problem: 1. the patient is asked to deliberately maintain bilateral ankle symmetry; 2. the patient can wind the rope around the sole of the foot by using articles such as the rope, the two ends of the rope are held by both hands, and the rope wound around the sole is tensioned by the patient to promote the relative fixation of the foot. Both methods can achieve certain effects, but still cannot meet the requirements of diagnosticians. Therefore, how to design a device capable of fixing the foot of the patient becomes a technical problem to be solved by those skilled in the art.
