Description

Technical Field

[0001] The utility model belongs to the field of medical instruments and relates to a thermotherapy auxiliary device, in particular to a precise measurement and positioning auxiliary device applied to thermotherapy equipment. Background Art

[0002] When technicians use thermotherapy equipment to treat patients, they need to accurately grasp the alignment of the thermotherapy radiation table with the patient's body surface lesion site and the patient's body width and thickness. At present, rulers, T-squares, and ordinary tape measures are used clinically to assist thermotherapy equipment in roughly measuring the patient's body width and thickness, but they cannot assist in the accurate measurement of body width and thickness. In addition, the high frequency of thermotherapy equipment requires the center position of the radiation table, the midline position of the mobile treatment robotic arm, and the patient's lesion site to be accurately aligned in three directions to achieve more effective treatment. At present, clinical technicians can only measure the patient's body thickness before treatment, and move the robotic arm multiple times to see whether the midline of the robotic arm is in the same straight line with the patient's lesion site. At the same time, the patient needs to move multiple times to ensure that the lesion is aligned with the middle position of the radiation table, which not only increases the technician's workload, but also takes some time to find the correct position, reducing the number of patients treated by this equipment in one day.
