Cervical cancer internal radiation therapy device

Abstract

The invention discloses a cervical cancer internal irradiation treatment device which comprises a cervical canal source applicator, a uterine orifice lip source applicator, a rotating mechanism, a perspective locating machine, and an after-loading control cabinet. The invention aims to provide a cervical cancer internal irradiation treatment device which has a novel structure, is safe and has programmed and target control functions. For cervical cancer treatment in hospitals nowadays, fixed-pattern programmed control is adopted, which poses harm to the human body. A two-hemisphere lateral adjustment source applicator is adopted in radiotherapy of uterine orifice lip, which has the defect of limited radiotherapy radiation surface. Thus, improvement is made on the treatment mode and device of cervical cancer. The technical key points are as follows: an iridium source cavity and the rotating mechanism are arranged to implement rotating radiotherapy of uterine orifice lip, programmed radiotherapy is implemented for patients with severe cervical cancer, and clinical dynamic inching target radiotherapy is implemented using the perspective locating machine for patients with mild cervical cancer, thus overcoming the shortcomings of the prior art and achieving the purpose of curative effect improving. The cervical cancer internal irradiation treatment device is applicable to clinical application of internal irradiation therapy of patients with cervical cancer.

Description

technical field [0001] The invention relates to an internal radiation therapy device for cervical cancer. Background technique [0002] At present, the incidence of cancer in our country is on the rise, especially the number of patients with cervical cancer is increasing. The internal irradiation device used in the hospital now has the inconvenience of operating the distance between the two hemispheres, the radiation area of ​​radiotherapy is small, and there is no positioning procedure. Therefore, it is necessary to improve the existing technology, check the condition before treatment, determine the treatment method according to the three-dimensional image data, implement non-positioning program-controlled internal radiation radiotherapy for patients with severe cervical cancer, and control internal radiation therapy for patients with mild cervical cancer. The implementation of inching targeted radiotherapy can improve the curative effect and reduce the harm to the human bo...
