Description

Fixed diaphragm for breast radiotherapy

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a fixed diaphragm for mammary gland radiotherapy.

Background

Radiotherapy is one of the main means of tumor therapy, and is to destroy the DNA of cancer cells by high-energy rays (X-rays, gamma rays, charged particles) to make them lose division and replication ability, thereby achieving the purpose of shrinking and eliminating tumor. Usually, a radiation treatment course needs to be irradiated for multiple times, so that the treatment position of a patient during each radiotherapy is kept consistent, meanwhile, the non-treatment position is protected, and the patient needs to be positioned and protected by a protective tool.

The low-temperature thermoplastic material is generally adopted to shape the human body clinically, and the shape is combined with a fixing frame product after being solidified to fix the treatment part of the patient. The low-temperature thermoplastic material can form a depression on the bony position with the bony mark, the depression is matched with the position of the bony mark of the human body, good fixation can be carried out, the position of the previous fixation of the patient can be easily found through the depression during reduction, and the method has good effect on the part fixation with obvious bony position.
