Abstract

Provided in the invention is a head fixation device for the sitting-posture type radiation therapy. The head fixation device comprises a backup plate, a head fixation bracket mounting frame, a head fixation bracket mounting frame adjusting mechanism, a head circumference fixation bracket adjusting mechanism, a head top fixation bracket adjusting mechanism, a jaw fixation bracket, and a jaw fixation bracket adjusting mechanism. During the radiation therapy process of a patient, the head fixation bracket mounting frame adjusting mechanism, the head circumference fixation bracket adjusting mechanism, and the head top fixation bracket adjusting mechanism that are installed on the backup plate are used adjust the head circumference fixation bracket and the head top fixation bracket to fix the head; and the jaw fixation bracket adjusting mechanism is used for adjusting the position of the jaw fixation bracket to fix the jaw of the patient. According to the invention, the head of the cancer patient in the sitting-posture type radiation therapy can be fixed and the sitting posture of the patient can be adjusted by cooperative with the radiation therapy chair, so that the radiation therapyis carried out accurately and thus the normal tissues are protected from being injured by the rays.

Description

Technical field: [0001] The invention discloses a head fixation device for sitting radiation therapy, and particularly relates to the field of radiation medical instruments. Background technique: [0002] The latest data from the World Health Organization shows that by 2020, the global cancer incidence rate will increase by 50%, that is, 15 million new cancer patients will be added every year. At present, for every 5 deaths in our country, 1 person dies of cancer. Cancer has become one of the main reasons threatening human health. There are three main ways to treat cancer: chemotherapy, radiotherapy, and traditional surgery. Among them, proton heavy ion radiotherapy is accepted by more and more doctors and patients because of its unique advantages and good curative effect. For proton heavy ion radiotherapy for head and neck tumors, the sitting posture is the best radiotherapy position. At present, the treatment chairs used for sitting radiotherapy on the market are less fu...
