Description

Technical Field

[0001] This utility model relates to the field of radiotherapy technology, specifically to an implantable radiotherapy fixator. Background Technology

[0002] Brachytherapy, also known as internal radiation therapy, sealed-source radiation therapy, radium therapy, or internal radium therapy, is a form of radiation therapy in which a radiation source is placed inside or near the site of treatment. Brachytherapy is widely used for cervical cancer, prostate cancer, breast cancer, and skin cancer.

[0003] For example, the utility model application with application number CN202420229362.7 relates to the field of medical auxiliary device technology and discloses an implantation radiotherapy positioning device. This implantation radiotherapy positioning device, by distributing the needle channel outlet in an elliptical ring shape, helps to reduce the radiation dose to the bladder and rectum, and reduce the occurrence of cystitis and proctitis. At the same time, the second needle channel on the left and right sides is symmetrically distributed, which can reduce the risk of accidental implantation into the bladder or rectum. When the implantation needle is inserted into the second needle channel and extends out from its rear end outlet, the rear end of the implantation needle has a certain outward angle, which can better meet the brachytherapy dose requirements of proximal cervical tumors. However, the existing implantation radiotherapy fixation device is not convenient for internal fixation of the implantation needle inside the device, resulting in poor fixation effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an implantable radiotherapy fixation device. Utility Model Content
