Description

Technical Field

[0001] The utility model relates to the field of radiotherapy positioning film related equipment, in particular to a radiotherapy positioning film pulling and fixing device. Background Technique

[0002] A radiotherapy positioning film is a fixing product made of a polymer material, which is characterized in that it softens at about 65°C and can be molded into any shape. Due to the advantages of softening at low temperature, strong plasticity, light weight, certain strength, easy operation, good X-ray permeability, and biodegradability after being discarded, it is currently widely used in radiotherapy positioning in the medical field. The existing technology usually puts the radiotherapy positioning film into water at 65-70°C, takes it out after softening for 2 minutes, places it on the part to be fixed for shaping, and fixes the side strip on the bottom plate to achieve the fixing purpose. After fixing, it is not convenient to adjust the tightness again. However, due to the characteristics of the material itself, it will continue to shrink after cooling, and the radiotherapy positioning film will rebound, resulting in the positioning film being tightened and pressing tightly on the patient during subsequent treatment, causing pain in the pressed part of the patient. When the patient is not satisfied with the plastic size, the positioning film can only be softened again, thus wasting time, manpower and resources.

[0003] Therefore, how to propose a pulling and fixing device that can still adjust the tightness of the positioning film after the side strip is fixed has become a difficult problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] The purpose of the utility model is to provide a radiotherapy positioning film pulling and fixing device to solve the problem that it is not convenient to adjust the tightness of the positioning film after the existing positioning film fixing side strip is fixed.
