Patient limb supporting device for radiotherapy department and using method thereof

Abstract

The invention discloses a patient limb supporting device for radiotherapy department and a using method of the patient limb supporting device. The device comprises a main body plate, screw rods, baffle plates and a head bracket, elastic assemblies are mounted on the left side and the right side of the main body plate, the outer side of the elastic assembly is connected with a side plate; a first lifting assembly is fixed to the front face of the upper portion of the side plate, a bearing support is fixed to the top end of the first lifting assembly, a second lifting assembly is mounted on thefront surface below the side plate; the top end of the second lifting assembly is connected with a servo motor; the screw rod is installed between the servo motor and the adjacent bearing support, theouter side of the screw rod is connected with a ball seat, the baffle plate is installed at the upper end of the movable block, an irradiation opening is formed in the middle of the baffle plate, thehead bracket is installed in the middle of the front face of the main body plate, and the outer surface of the main body plate is connected with a sponge cushion. The baffle plate is arranged betweena therapeutic machine and an accelerator, so that normal tissues of a patient are protected from being damaged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a support device for a patient's limb used in a radiotherapy department and an application method thereof. Background technique [0002] There are two types of tumors, benign and malignant. The benign ones are called tumors, and the malignant ones are called carcinomas or sarcomas. Malignant tumors can be divided into two types histologically. Malignant transformation of lung epithelial cells forms lung cancer, malignant transformation of gastric epithelial cells forms gastric cancer, etc.; another type of malignant transformation of mesenchymal tissue is called sarcoma, such as leiomyosarcoma, fibrosarcoma, etc. People hear more about cancer, but less about sarcoma, which is related to the fact that there are far more cancer patients than sarcoma patients. Radiation therapy is the treatment of malignant tumors and some benign diseases by using one or more ionizing radiat...

Problems solved by technology

[0004] The purpose of the present invention is to provide a patient's limb support device for radiotherapy and its use method, which solves the problem that the radiation bed is not convenient to limit and support the patient's limbs in the current clinical radiotherapy operation, and the patient is in the radiotherapy process. Disturbance can easily cause the affected area to deviate from the ray irradiation range, and during the ray irradiation process, the existing irradiation bed is not convenient for shielding the patient's normal tissue, which leads to the problem that the radiation damages the patient's normal tissue
