Intraoperative radiotherapy device

Abstract

The invention relates to an intraoperative radiotherapy device. According to one embodiment, the intraoperative radiotherapy device can include a rack; an MDOF parallel motion platform mounted on therack and capable of realizing translation and rotation in multiple directions; and an intraoperatiove radiotherapy device radiation head, whose one end is connected with the rack in a movable manner,fixedly connected to the MDOF parallel motion platform. By utilizing the MDOF parallel motion platform, spatial movement of the intraoperatiove radiotherapy device radiation head is driven, so that the intraoperatiove radiotherapy device radiation head can align to a tumor bed area for radiotherapy. Besides, before the treatment, the MDOF parallel motion platform is utilized for driving an ultrasonic imaging device and the like to image the tumor bed area, so that image-guided intraoperative radiotherapy is realized. The intraoperative radiotherapy device has characteristics of compact structure, flexible operation, high motion precision and the like.

Description

technical field [0001] The present invention generally relates to the field of medical devices, and more particularly, relates to an intraoperative radiotherapy device based on a multi-degree-of-freedom parallel motion platform. Background technique [0002] Intraoperative radiation therapy technique, also known as intraoperative radiotherapy, refers to the intraoperative administration of a single dose of high-dose radiation to the primary tumor bed, residual tumor, or lymphatic drainage area in the case of surgical resection of the tumor or surgical exposure of an unresectable tumor It can protect the surrounding normal tissues while the tumor and tumor cells are directly exposed to high-dose radiation, thereby improving the local control rate, survival rate and quality of life. Intraoperative radiotherapy technology has gradually become an important part of comprehensive tumor treatment, and various intraoperative radiotherapy devices have emerged one after another, such ...

AI Technical Summary

Problems solved by technology

[0003] However, there are still many deficiencies in the above-mentioned radiotherapy device.

First of all, in order to realize the multi-degree-of-freedom movement of the radiation head in the intraoperative radiotherapy device, the mechanical device used is too complex, bulky and poor in operation flexibility

In addition, the lack of image-assisted positioning devices makes it impossible to achieve image-guided intraoperative radiotherapy

Moreover, the radiation head of the intraoperative radiotherapy device and the treatment light-limiting tube need to be manually centered, which is complicated to operate and poor in centering accuracy, which is not conducive to achieving accurate intraoperative radiotherapy
