Description

Ankle back extension fixing device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a ankle dorsum stretching position fixing device.

Background

Ankle disease requires ankle fixation to be maintained in the dorsi-extended 90 ° position (when the ankle joint is in the dorsi-extended functional position) during X-ray, CT or MRI examinations, thus obtaining a photograph of the standard position. When the patient stands normally, the ankle joint is positioned at the back stretching 90 degrees, but when the X-ray film is shot by a conventional CT and MRI machine, due to equipment limitation (the patient cannot be positioned at a standing position on an inspection device), the patient needs to lie flat and can not maintain the ankle joint at the back stretching 90 degrees, so that the inspection is performed in a non-standard positive side position and a side shaft position, and the observation of doctors is influenced. The foot of the user is pulled through the ankle dorsum stretching position fixing device, so that the ankle joint of the user keeps dorsum stretching 90 degrees, the conventional CT and MRI machine can replace the CT and MRI machine with load, and standard ankle positive lateral position and calcaneus lateral axial X-ray can be obtained. The patent application with the application number of CN200620011027.1 and the application name of the ankle traction device for patella axial X-ray photography discloses a holding ring, a traction belt and a soft cushion; one end of the traction belt passes through the holding ring and is fastened by the belt clamp, and the other end of the traction belt sequentially passes through the two pull rings on the soft cushion and is fastened by the belt clamp and is connected with the soft cushion. When the device is used, a patient swings the body position, wraps the soft cushion on the ankle of the detected side, adjusts the length of the device, and then tightens the holding ring by hand. In this patent application, the ankle joint is required to be positioned at the back-extension 90 ° by the continuous force applied by the hand of the user, and the user is typically a patient in a hospital, and if the user is in a weak state, the force cannot be applied continuously, so that the shooting cannot be completed. In addition, the cushion bag, the holding ring and the traction belt of the application are not detachable, and are inconvenient to clean and disinfect. Thus, the drawbacks are quite apparent and there is a need to provide a solution.
