Description

Technical Field

[0001] This utility model belongs to the field of interventional radiotherapy technology for portal hypertension, and specifically relates to a positioning device for interventional radiotherapy for portal hypertension. Background Technology

[0002] Portal hypertension is a pathological condition, usually caused by cirrhosis of the liver, which obstructs blood flow in the portal venous system, leading to increased portal venous pressure. Interventional radiotherapy is a non-surgical treatment method that uses minimally invasive techniques to reduce portal venous pressure and improve patients' symptoms and quality of life. During interventional radiotherapy for portal hypertension, it is necessary to immobilize the patient to prevent movement due to discomfort during treatment, which could affect the actual treatment and, in severe cases, lead to medical accidents. The head is more sensitive than other parts of the body, and the instinct to move due to discomfort is more urgent during prolonged treatment. Different patients have different body shapes and adaptive postures. Common positioning devices used in interventional radiotherapy for portal hypertension cannot be adaptively adjusted, and discomfort may occur after head and neck immobilization. Poor adaptability of the positioning device may cause the patient to move unbearably during treatment, affecting the actual radiotherapy.

[0003] In summary, the positioning device for interventional radiotherapy of portal hypertension, which cannot be adaptively adjusted, has some problems in use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
