Problems solved by technology

[0003] For the discussion on the radiotherapy position, please refer to: Zheng Zuan et al., "Discussion on the Concept of Radiotherapy Position Fixation Technology". Structure, the body skin and the tissues and organs in the body have relative motion when they are positioned for radiotherapy, similar to a pocket containing items, and there is relative motion between the pocket and the items when they move. This phenomenon is called "capsular bag effect" "; the body of the human body is similar to a cylinder. When the radiotherapy is set up, because the human body rotates, it will also drive the internal organs to move accordingly. This phenomenon is called the "cylinder effect"; The "capsule effect" and "cylindrical effect" of the human body make the operation complicated during the positioning process, and it is necessary to wait for the fixing materials used to be finalized after a corresponding period of time, and it is difficult to achieve the same accuracy and repeatability as head positioning Therefore, it is necessary to assist certain fixation devices in the process of patient treatment
[0004] According to the different parts of the radiation therapy, different fixation methods and different auxiliary materials are used to fix the patient; the fixation materials include the cushion (vacuum cushion) made of special materials and the fixation film covering the body surface (Body film), etc.; the general principle is that the repeatability of body position fixation is good (because multiple irradiations are required), and the patient's comfort is good (to ensure that the fixation time can be relatively long); each time you set up a position, you need to move and rotate repeatedly The human body satisfies the position accuracy required by radiotherapy, so it takes a long time to set up the position, prolongs the time for the radiotherapist to maintain a fixed posture, and reduces the comfort experience of the radiotherapist

Embodiment approach

[0041] As an embodiment of the present invention, the two sides of the positioning frame 1 are slidingly installed with a pallet 5, and the side of the pallet 5 facing the inside of the positioning frame 1 is fixed with a raised pad 50, and the pad 50 is located at Below the omentum plate 2, the support table 5 slides close to the body of the radiotherapist; through the provided support table 5, it moves along the two sides of the longitudinal axis of the positioning frame 1, and when performing radiotherapy positioning, operate the support table 5 The table 5 moves to both sides of the radiotherapist's body, and the platform pad 50 on the supporting table 5 is used to protrude from the inner wall of the positioning frame 1 to approach the omentum plate 2 and press against the radiotherapist's body parts, increasing the position of the radiotherapist. It also plays a supporting role for the omentum plate 2, reducing the possibility of excessive deformation of the omentum plate ...

Abstract

The invention belongs to the technical field of radiotherapy, and particularly relates to a comfortable radiotherapy body position fixing frame which comprises a positioning frame, an omentum plate, a reset unit and a posture controller. When radiotherapy positioning is carried out each time, a human body needs to be repeatedly moved and rotated to meet the position precision required by radiotherapy, so that the time consumed by positioning is long, the time for a patient to keep a fixed posture is prolonged, and the comfort experience of the patient to be radiotherapy is reduced. Therefore, through the arrangement of a return assembly and a rotation assembly, the operation of an electric control translation stage and an electric control rotation frame is controlled in real time through the monitoring of an angular velocity sensor in the posture controller, so that the posture variation generated by a radiotherapy part and a radiotherapy equipment head is reduced as much as possible when the body posture of a radiotherapy person is adjusted after the posture of the human body is changed, the posture variation of the radiotherapy part of the human body and the radiotherapy equipment head is controlled within the range required by the radiotherapy process, and the comfort experience of the human body in the radiotherapy process is improved while the stable radiotherapy is ensured.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy, in particular to a comfortable radiotherapy body position fixing frame. Background technique [0002] Radiation therapy is a method of treating tumors by killing cancer cells with ionizing radiation of high-energy rays. The entire process of radiotherapy is irreversible, and the total amount of radiation received by each body part is limited. To achieve accurate irradiation of rays In the tumor lesion area, the patient’s body needs to be fixed as necessary. According to the requirements of the radiotherapy position, on the one hand, the patient needs to use the position auxiliary device to obtain the correct treatment position, and on the other hand, the position is required to remain unchanged during the treatment process, or The position can be repeated each time, preventing the patient from changing the position due to subconscious movements during treatment. [0003] For the discussion ...
