Radiotherapy positioning device for nasopharyngeal carcinoma tumors

Abstract

The invention discloses a radiotherapy positioning device for nasopharyngeal carcinoma tumors, and relates to the field of medical instruments. The device including a base, a sliding groove is formedin the side wall of the upper end of the base, a threaded rod is rotationally connected into the sliding groove, a servo motor is mounted in the base, the tail end of an output shaft of the servo motor is fixedly connected to the end part of the threaded rod, the outer side wall of the threaded rod is in threaded connection with two threaded sleeves, the upper ends of the two threaded sleeves arefixedly connected to moving plates, sliding grooves are formed in the opposite sides of the two moving plates, and sliding blocks are slidably connected to the inner side walls of the two sliding grooves correspondingly. Through cooperative use of the threaded rod, the threaded sleeves, a rotating rod, a connecting plate, a first buffer pad, a first arc-shaped plate and a driving motor, clamping and fixing of the head position of the human body and adjustment of the height of the head position of the human body are achieved, and the comfort degree of a patient is effectively improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a radiotherapy positioning device for nasopharyngeal carcinoma tumors. Background technique [0002] Nasopharyngeal carcinoma refers to malignant tumors that occur on the roof and side walls of the nasopharyngeal cavity. It is one of the high-incidence malignant tumors in my country, and its incidence rate is the first among ear, nose and throat malignant tumors. Common clinical symptoms are nasal congestion, blood in the nasal discharge, ear blockage, hearing loss, diplopia, and headache. Most nasopharyngeal carcinomas are moderately sensitive to radiotherapy, and radiotherapy is the first choice for the treatment of nasopharyngeal carcinoma. However, surgical resection and chemical drug treatment are also indispensable means for highly differentiated cancers with a late course and recurrence after radiotherapy; [0003] In the process of chemotherapy for nasopharyngeal carcino...

Problems solved by technology

However, surgical resection and chemical drug treatment are also indispensable means for highly differentiated cancers with a late course and recurrence after radiotherapy;

[0003] In the process of chemotherapy for nasopharyngeal carcinoma, it is usually necessary to position the patient to avoid the movement of the patient and affect the chemotherapy work. The traditional way is to realize the positioning of the patient through two clamping plates, which can neither effectively Adjust the work according to the size of the patient's head, and at the same time, it cannot completely clamp the patient's head. At the same time, the traditional method cannot adjust the height, which will easily cause the patient's discomfort. For this reason, a nasopharyngeal cancer tumor Radiotherapy positioning device to solve the above problems
