Hand fixing device based on carbon fiber integrated plate in radiotherapy process

Abstract

The present invention belongs to the technical field of hand fixing devices and particularly relates to a hand fixing device based on a carbon fiber integrated plate in a radiotherapy process. The hand fixing device comprises a carbon fiber integrated plate main body, two first mounting grooves are arranged in left and right sides of an upper end surface of the carbon fiber integrated plate main body in a penetrating way, two second mounting grooves are arranged in the left and right sides of the upper end surface of the carbon fiber integrated plate main body in a penetrating way, the two second mounting grooves are respectively positioned in front of the two first mounting grooves, upper end surfaces of the two first mounting grooves and the two second mounting grooves are respectively provided with a fixing device main body, a plurality of clamping grooves distributed in a front-and-back parallel manner are arranged in upper end surfaces of the two fixing device main bodies in a penetrating way, two inserting columns matched with the clamping grooves are both arranged on the upper end surfaces of the two fixing device main bodies, and upper end surfaces of the two inserting columns are both fixedly connected with holding rods, so that a problem that hands of a patient cannot be fixed is solved and treatment accuracy of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of hand immobilization devices, in particular to a hand immobilization device based on a carbon fiber integrated plate during radiotherapy. Background technique [0002] Radiotherapy position repetition and position fixation are an extremely important link in the process of radiotherapy planning and positioning. Due to the adoption of high-precision linear accelerators, protons, simulated positioning machines, treatment planning systems, and advanced imaging diagnostic equipment such as CT and MR, high-precision tumor positioning, treatment planning and high-precision treatment can be obtained, so "three precision" radiotherapy The development of the practice puts forward higher requirements for the repeatability of position fixation and fractionated treatment. The dose distribution of the IMRT treatment plan is very steep, and an error of 1mm in the area where the dose changes are steep can cause a dose di...
