Tumor radiotherapy positioning and fixing device

Abstract

The invention provides a tumor radiotherapy positioning and fixing device, and relates to the technical field of medical apparatuses and instruments. A fixed arc block is slidably mounted at the rear end of the fixed table, and two placement grooves are formed in the right end of the fixed table; leg fixers are mounted in two placement grooves in the fixed table respectively, and threads of the two leg fixers are mounted at the two ends of a movable seat; a supporting assembly is mounted at the bottom end of the fixed table; the head of a patient can be conveniently fixed, the bottoms of knee joints or shank fixing positions of the patient can be conveniently fixed and the height of the knee joints or shank fixing positions can be conveniently adjusted through the leg fixing devices according to radiotherapy requirements, and the supporting performance of the legs of the patient and the adjustability of the angle of a leg radiotherapy surface are improved; the fixing table can adapt to different positions of knee joint bottom fixing positions of different patients, and the height of the fixing table is convenient to adjust; the problems that the head and the bottoms of knee joints or shanks of a patient are not easy to fix according to radiotherapy requirements and the adjustable performance is poor are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a positioning and fixing device for tumor radiotherapy. Background technique [0002] Tumor radiation therapy is a local treatment method for tumors treated with radiation, and the patient's body needs to be fixed during local radiation therapy; however, as far as the current traditional radiation therapy fixation device is concerned, it is not easy to fix the patient's head and knee joint The bottom or calf is fixed according to the needs of radiotherapy, the adjustable performance is not good, the height of the fixed part at the bottom of the knee joint or the calf is not easy to adjust, the support of the patient's leg and the adjustable effect on the angle of the radiotherapy surface of the patient's leg Poor, can not adapt to the different positions of the bottom of the knee joint or the fixed part of the calf of different patients, and it is not easy to adjust the h...
