Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy positioning lines, in particular to an improved radiotherapy positioning line drawing device. Background Art

[0002] When the hospital performs radiotherapy on patients, after positioning the patient according to the tumor location and radiotherapy needs, a laser locator is used to form a cross projection at the appropriate location on the patient's body surface, and then a scratching fluid is used to mark the cross line (i.e., the positioning mark line) at the projection to determine the location of the target area. This can help doctors accurately locate the tumor during radiotherapy and ensure that the radiation is accurately irradiated to the tumor location.

[0003] Existing radiotherapy positioning marking lines are generally drawn directly with a marker pen, and the markings can be made less likely to fade after being air-dried. However, it takes some time for the markings to dry naturally after being drawn. If the markings are touched or rubbed by clothing before they are dry, the markings will become blurred or disappear, which will affect the accuracy of subsequent radiotherapy positioning.
