Positioning radiotherapy device based on carrier plate and working method

Abstract

The invention provides a positioning radiotherapy device based on a carrier plate and a working method, and relates to the field of medical equipment. The positioning radiotherapy device comprises a first ring and a second ring which are coaxially arranged, wherein a kinematic pair is matched between the first ring and the second ring, and the first ring and the second ring are driven to generaterelative rotation; the carrier plate is arranged on the inner ring of the first ring and used for bearing a patient; a positioning mechanism is arranged on the first ring and used for obtaining a radiotherapy target area; and a radiotherapy mechanism is arranged on the second ring, and the second ring drives the radiotherapy mechanism to rotate according to the focus position to adjust the workingposition and conduct radiotherapy on the target area. The positioning mechanism and the radiotherapy mechanism are configured respectively through the first ring and the second ring coaxially arranged, and an electronic slip ring is configured in the middle to enable the positioning mechanism to be matched with the radiotherapy mechanism, so that the purpose of positioning a target area while performing radiotherapy on the target area is achieved, operation steps in the radiotherapy process of the patient are saved, and the radiotherapy efficiency and precision are improved.

Description

technical field [0001] The present disclosure relates to the field of medical equipment, in particular to a positioning radiotherapy device based on a carrier plate and a working method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the continuous development of the times and the continuous advancement of science, medical technology and medical equipment are also constantly improving in order to provide patients with better treatment and services. In the traditional radiotherapy process, the radiotherapy process is generally divided into four steps: positioning - making radiotherapy plan - reset - treatment. After the radiotherapy doctor's outpatient visit, the patient needs to go through body position fixation and radiotherapy simulation positioning to ensure accurate radiotherapy, and at the same time ensure good position repea...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that at present, after determining the radiotherapy target area, it is necessary to draw a marker line on the skin of the patient's body surface and set up a corresponding auxiliary bracket, so that the patient can determine the radiotherapy position through the marker line and the auxiliary bracket after being transferred to the radiotherapy instrument; The transfer of the body needs to rely on the landmark line and auxiliary bracket to re-determine the radiotherapy target area, which will inevitably cause positioning errors, resulting in the incomplete correspondence between the radiotherapy process and the radiotherapy target area; The radiotherapy target area is adjusted according to the previous radiotherapy situation, and the traditional radiotherapy method still needs to be repositioned after re-determining the location and size of the tumor, resulting in a longer overall period of the radiotherapy process; traditional radiotherapy equipment and tumor inspection equipment are divided into Asana structure, it is difficult to adjust the radiotherapy position in real time according to the situation of the radiotherapy target area, and it is difficult to meet the needs of existing patients for radiotherapy treatment
