In the future high-tech wars, field exciting medical equipment is an important medical institution for the treatment of the wounded in wartime, and it is also an important medical component of major disaster rescue. However, the field environment Unfortunately, traditional bulky CT scanners not only take up a lot of space, but also cannot provide timely bedside scanning services for critically ill patients.

According to Patent No. 201611271461.8, the present invention discloses a cage-type CT scanner, mainly by reducing the volume and weight of the CT scanner, reducing the rotation radian of the rotating parts and the vibration amplitude of the whole machine, and at the same time eliminating the need for balance correction. The vibration of the CT scanner itself can be reduced and eliminated by means of transmission eccentric force and other measures. The invention cancels the mechanical transmission chain of the belt covering method to reduce the number of components in the motor synchronous structure, which not only reduces the cost, but also satisfies the requirements for the working ground. However, when the scanner is used in the field, due to the uneven road surface, the mechanical arm fixed on the top of the base will be inclined, so that the output angle of the scanner will change and the scanning will be reduced. In addition, when the scanner is working, the patient's body needs to be moved to the scanning part of the scanner. Due to the limitations of the workplace, it is easy for the patient to shake when moving, and it is difficult to move to an appropriate position, which reduces the scanner's performance. scanning efficiency. To this end, we propose an adjustment device for a cage CT scanner.
