Abstract

The invention provides a chest radiation-oncology positioning device. The chest radiation-oncology positioning device comprises a fixed frame and a positioning mechanism, a chest-belly positioning groove is formed in the fixed frame, and multiple pressing mechanisms for pressing the positioning mechanism are also arranged at the portions, located on the two sides of the chest-belly positioning groove, on the fixed frame; the positioning mechanism comprises a lower positioning film arranged in the chest-belly positioning groove and connected with the fixed frame, an upper positioning film located on the lower positioning film and connected with the fixed frame and vacuum pads arranged between the upper positioning film and the lower positioning film. According to the chest radiation-oncology positioning device, the lower positioning film is used for positioning the back after a patient lies, the lower positioning film can firmly fit the back of the patient, and the problem that as a gapexists between the back of the patient and the fixed frame, and the patient slightly moves, the treatment effect is influenced is solved; the vacuum pad can also be spliced on the positioning face ofthe upper positioning film or the positioning face of the lower positioning film, the vacuum pads are vacuumized to be formed according to the lying gesture of the patient, the gap between the upperpositioning film or the lower positioning film can be filled with the vacuum pads, and the positioning accuracy is further increased.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy equipment, and more specifically relates to a chest radiotherapy positioning device. Background technique [0002] At present, in tumor radiotherapy, radiologists need to fix the patient's body position to ensure the accuracy of treatment. In chest radiotherapy for lung cancer, esophageal cancer, and pleural cancer, it is necessary to use a chest radiotherapy positioning device to fix the patient's chest. [0003] The chest radiotherapy positioning device in the prior art includes a fixing frame and a positioning film. During radiotherapy, the patient lies supine on the fixing frame, and the positioning film is heated, deformed and elongated, and covers the patient's chest and abdomen for positioning. The positioning requirements of radiation therapy are fixed and accurate in the three-dimensional directions of up and down, left and right, and front and back, and the movement error is less th...
