Problems solved by technology
[0002] At present, the incidence of tumors at home and abroad is increasing year by year, especially gynecological tumors are relatively common. Most of them use two-dimensional plane positioning in clinical practice, which has poor accuracy. In recent years, three-dimensional positioning has been gradually carried out clinically. , move the patient's position repeatedly during positioning and treatment, and the source applicator for brachytherapy changes greatly during the moving process, which makes the positioning CT scan image inconsistent with the treatment image, and the repeatability of the clinical treatment position is poor, which affects the treatment effect. Therefore, it is urgent It is necessary to develop a device that can effectively cooperate with CT scanning to meet the needs of short-distance three-dimensional treatment.

Embodiment Construction
[0018] The present invention will be described in further detail below with reference to the accompanying drawings and examples. For the embodiments, see Figure 1, Figure 2, image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , The carbon fiber bottom plate is screwed to the limit plate 5 and placed on the working platform of the CT machine. The position plate 2 is provided with a head-up device 7 and the articulation 18 is movably connected with the position plate 2, and the displacement slot 14 is used to adjust the head-up angle. The raised head support (2) 16 is movably connected with the raised head panel 25. When the pull handle 19 and the hinge 18 are rotated, the raised head panel 25 is held up, and the raised head support (2) 16 is movably placed in the displacement slot 14 To form the required inclination angle, the leg setting device 8 is composed of the thigh leg plate D and the calf leg plate X. The two parts are assembled through the joint 17 and the joint 20 res...

The invention discloses a three-dimensional body frame for short-range therapy, and aims to provide a three-dimensional stereotactic body frame capable of meeting precise therapy demand. The body frame comprises a carbon fiber bottom plate 1, a body position plate 2 and a rolling device 3. The three-dimensional stereotactic body frame is realized by adopting the following technical proposal: the carbon fiber bottom plate 1 is placed on a workbench of a CT machine; the body position plate 2 is provided with an overhead device 7, a leg supporting device 8, and a pelvic cavity pool set 9; the rolling device 3 is fixed on the body position plate 2 by a screw to form the body frame; and clinically, overhead and leg supporting postures are adjusted well respectively, the body position plate 2 is placed in a rolling mode along the carbon fiber bottom plate 1, and then a patient lies on the body position plate 2 and is subjected to CT scanning and three-dimensional stereotactic radiation therapy. The three-dimensional stereotactic body frame is applied to CT scanning and three-dimensional positioning for tumors in cavities in hospitals, and achieves precise therapy of three-dimensional stereotactic radiation.
Description
Technical field [0001] The invention 1 relates to a brachytherapy three-dimensional body frame for clinical application. Background technique [0002] At present, the incidence of tumors at home and abroad is increasing year by year. In particular, gynecological tumors are relatively common. Most of them use two-dimensional planar positioning in clinical practice, which has poor accuracy. In recent years, three-dimensional positioning has been gradually developed in clinical practice. However, due to the positioning devices and methods used , The patient’s position is repeatedly moved during positioning and treatment. The applicator for brachytherapy changes greatly during the movement, which makes the positioning of the CT scan image and the treatment image inconsistent, and the clinical treatment position is poorly repetitive, which affects the treatment effect. This is urgent It is necessary to develop a method that can effectively cooperate with CT scanning to meet the needs ...
