Fixing and positioning device for radiotherapy

Abstract

The invention discloses a fixing and positioning device for radiotherapy, and belongs to the technical field of radiotherapy. The device comprises a bed body, a plurality of fixing seats are fixedly connected to the front side and the rear side of the upper end of the bed body respectively, a front threaded rod and a rear threaded rod are rotatably connected to the fixing seats through threads respectively, T-shaped shafts are fixedly connected to the front threaded rod and the rear threaded rod respectively, and the T-shaped shafts are rotatably connected with a front baffle and a rear baffle. The fixing seats are fixedly connected to the front side and the rear side of the upper end of the bed body respectively, and the front baffle and the rear baffle are limited and fixed through the front threaded rod and the rear threaded rod respectively, so that the upper body and the lower body of a patient can be limited and fixed through the front baffle and the rear baffle respectively, troubles caused by shaking of the upper body and the lower body without shielding of the fixing device can be avoided, and the front arc-shaped plate and the rear arc-shaped plate are limited and fixed through the ejector rod, the front end and the rear end of the head of the patient can be conveniently limited and shielded through the front arc-shaped plate and the rear arc-shaped plate, and the phenomenon that the head shakes is avoided.

Description

technical field [0001] The present invention relates to the technical field of radiotherapy, and more specifically, relates to a fixed positioning device for radiotherapy. Background technique [0002] The professional training of radiotherapy technology faces the 21st century. It has the basic theoretical knowledge and basic skills necessary for basic medicine, clinical medicine and modern medical imaging. marketing etc. [0003] At present, there is no fixed positioning device on the upper end of the radiotherapy bed, and long-term stillness is likely to cause numbness and cramps in the patient's body and head, which makes the patient prone to shaking, which is likely to have adverse effects on radiotherapy. If the height is too high and the length of the radiation therapy bed is not long enough, the patient's feet will be suspended in the air, and the long-term suspension will easily make the patient's feet uncomfortable.

Problems solved by technology

[0003] At present, there is no fixed positioning device on the upper end of the radiotherapy bed, and long-term stillness is likely to cause numbness and cramps in the patient's body and head, which makes the patient prone to shaking, which is likely to have adverse effects on radiotherapy. The height is too high and the length of the radiation therapy bed is not long enough, resulting in the phenomenon that the patient's feet are suspended in the air. Long-term suspension can easily make the patient's feet uncomfortable
