Description

Technical Field

[0001] This utility model relates to the field of developer adjustment technology, specifically a developer adjustment device for an applicator. Background Technology

[0002] Brachytherapy applicators are primarily used in brachytherapy, a crucial method in modern cancer treatment. By placing a radiation source directly within or near the tumor tissue, the radiation energy is precisely applied to the tumor, effectively killing tumor cells while minimizing damage to surrounding healthy tissues.

[0003] An applicator is used to guide a radiation source to the tumor tissue. During treatment, the doctor selects a suitable applicator based on the location and shape of the tumor and inserts it into the patient's body. Then, the radiation source is delivered into the applicator through a catheter to irradiate the tumor tissue. Parameters such as irradiation time, dose, and number of irradiations are adjusted according to the patient's specific condition. Therefore, a contrast agent adjustment device is needed to adjust the position of the contrast agent during applicator placement. The inability of the applicator to be visualized during MR localization in brachytherapy severely hinders the development of brachytherapy MR localization technology. Currently, sterile cotton balls soaked in gadolinium-containing contrast agent are usually inserted into the vagina for visualization and easy identification of the applicator. However, blood is often present in the vagina when the applicator is placed, and cotton balls mixed with blood can cause bacterial or other microbial growth, increasing the risk of infection. Furthermore, it is difficult to control the moisture content of the cotton ball; wet cotton balls often leak fluid, affecting patient comfort. The cotton ball must be evenly wrapped around the applicator for better visualization, which requires high technical skill and is complex to operate. Utility Model Content
