Angiography-based esophageal cancer radiotherapy positioning device

Abstract

The invention discloses an esophageal cancer radiotherapy positioning device based on radiography and relates to the technical field of medical treatment. The device comprises a device body, a hose is mounted on one side of the device body, a measuring tube is mounted at one end, away from the hose, of the device body, and a connector is mounted at one end, away from the device body, of the hose. Placing holes are formed in the device main body, the hose and the measuring tube; in the using process of the device body, the size of the canceration position of a patient is measured according to the difference between the first scale and the second scale, a good positioning and detecting function is achieved, follow-up radiotherapy positioning is facilitated, the fixing structure plays a good supporting and fixing role, the device body is prevented from sliding off in the handheld process, and the practicability of the device body is improved; the replacement structure facilitates replacement of connectors of different sizes, deformation of the mounting head and the mounting groove due to large stress is prevented, and the replacement of the connectors facilitates positioning detection of different patients.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a radiotherapy positioning device for esophageal cancer based on contrast. Background technique [0002] Esophageal cancer is a relatively common malignant tumor disease in daily life, which is located in the upper gastrointestinal tract. At present, the treatment methods for this disease include surgery, radiotherapy and chemotherapy. In these methods, radiotherapy plays an important role, and radiotherapy requires the use of positioning devices. However, the existing radiotherapy positioning devices based on contrast have certain limitations. The disadvantages are, firstly, during the use of the main body of the device, the radiotherapy positioning of the patient is not accurate, and the operation is relatively cumbersome. Secondly, during the use of the main body of the device, the hand is not stable enough, and there is no corresponding fixed structure, which is not convenie...

Problems solved by technology

At present, the treatment methods for this disease include surgery, radiotherapy and chemotherapy. In these methods, radiotherapy plays an important role, and radiotherapy requires the use of positioning devices. However, the existing radiotherapy positioning devices based on contrast have certain limitations. The disadvantages are, firstly, during the use of the main body of the device, the radiotherapy positioning of the patient is not accurate, and the operation is relatively cumbersome. Secondly, during the use of the main body of the device, the hand is not stable enough, and there is no corresponding fixed structure, which is not convenient for its long-term use. Finally , during the positioning detection process of the main body of the device, the size of the esophagus of different patients is different, and the connector cannot be replaced, which makes the positioning and maintenance effect poor, and cannot be applied to different patients, reducing its practicability. For this reason, the staff in this field proposed A radiotherapy positioning device for esophageal cancer based on contrast
