Problems solved by technology

When the patient's intracranial lesion is in a relatively partial position, such as a calculation error when planning the treatment space, or an error in the motion control system, etc., the actual movement distance of the three-dimensional treatment table exceeds the space of the irradiation treatment chamber. It will cause the patient's head positioning device to accidentally hit the treatment cavity wall of the rotating collimator, causing serious consequences

Embodiment Construction

[0022] For ease of understanding, the specific implementation structure and workflow of the present invention are described below in conjunction with the accompanying drawings:

[0023] The concrete implementation structure of the present invention refers to Figure 1-4 As shown, it includes the drive shaft 10 and the rotating collimator 20 that constitute the main body, and the shape of the rotating collimator 20 presents figure 1 The hood-like or barrel-like structure shown. The cover back of the rotating collimator 20 , that is, the bottom surface of the cover outer wall is coaxially connected to the drive shaft 10 , and is rotatably fixed on the radiation frame with a bearing unit in the shape of a simply supported beam. Through the above-mentioned structure, when the radiation equipment is working, the drive shaft 10 is driven by the power source to rotate, and the rotating collimator 20 can be driven to rotate accordingly, so as to achieve irradiation therapy by using t...

Abstract

The invention belongs to the field of radiation source disassembly and assembly equipment, and in particular relates to an anti-touch device for head radiotherapy equipment. The device includes a drive shaft and a rotating collimator. The device also includes a floating cover whose outline conforms to the shape of the cover cavity of the rotating collimating body. Radial movable fit gap; a mechanical high-precision micro switch is set at the fit gap between the floating cover and the rotating collimator, and the mechanical high-precision micro switch is more than two housing cavity walls surrounding the rotating collimator The intervals are evenly distributed, and the switch end of the mechanical high-precision micro switch points to the direction of the outer wall of the floating cover. The invention can reliably realize the purpose of floating protection of the rotating collimator itself and even the rotating collimating body relative to the patient's head from the treatment preparation stage to the treatment process, and ultimately ensure the safety and reliability of the working process.

Description

technical field [0001] The invention belongs to the field of radiation source disassembly and assembly equipment, and in particular relates to an anti-touch device for head radiotherapy equipment. Background technique [0002] Malignant tumors are one of the main causes of death among Chinese residents. At present, there is no specific treatment for malignant tumors in humans. Radiation therapy, chemotherapy and surgery are the three major means of treating tumors at this stage. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. Radiation therapy equipment is usually divided into two categories: head tumor radiotherapy equipment and body tumor radiotherapy equipment. Most of the existing radiation therapy equipment for head tumors use a rotating collimator with a spherical cavity or a cone cavity as the irradiation treatment cavity. During treatment, the patient lies supine on the thre...
