Radiotherapy positioning equipment for oncology department

Abstract

The invention discloses radiotherapy positioning equipment for the oncology department. A positioning bed plate comprises a head bed plate, a shoulder bed plate and a main bed plate which are separated from one another, are arranged in a horizontal straight line and are all slidably mounted on a bearing plate, and a mounting frame is horizontally and slidably arranged in a first transmission cavity. The mounting frame can slide in the horizontal direction and the vertical direction under the limiting and guiding effects of the first transmission cavity, a plurality of elastic telescopic rods are horizontally arranged in a groove, on the left side of the first sliding block, of the mounting frame, and the elastic telescopic rods apply horizontal rightward thrust to the first sliding block all the time. A rotatable lead screw shaft is horizontally installed on the upper portion in a second transmission cavity, and a driving shaft is inserted into a rotation limiting strip hole through three transmission cavity guide rods at the same time, so that when a cylindrical gear rotates, the guide rods push the first sliding block to move horizontally. The body position of a patient can be flexibly adjusted, and the equipment is simple, reliable and easy to maintain and manufacture.

Description

technical field [0001] The invention relates to the technical field of tumor radiotherapy, in particular to a radiotherapy positioning device for oncology departments. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors; about 70% of cancer patients need radiation therapy during the treatment of cancer, and the patient needs to be fixed during radiation therapy, so it is necessary to Develop a device that can be used to fix the tumor in patients for adjuvant therapy. [0003] Most of the positioning devices on the market cannot be used by patients of different sizes. The overall flexibility of the positioning bed is poor, and it cannot provide local position fixation for smaller patients, and cannot ensure the smooth progress of tumor treatment. In addition, although the functions of some highly automated equipment are perfect, the structure is extremely complex, the cost is high, and the maintenance is ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a radiotherapy positioning device for oncology to solve the problem that most of the existing related positioning devices proposed in the above background technology cannot be adapted to patients of different body types, and the overall flexibility of the positioning bed board is poor and cannot be of different body types. Smaller patients are provided with partial position fixation, which cannot ensure the smooth progress of tumor treatment and cannot improve the comfort of the patient's lying position
