Beam Needle Electron Radiotherapy for Precise Tumor Ablation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiotherapy methods cause harm to normal tissues and are painful for patients due to the accumulation of energy in tissues before and behind the tumor lesion site, and they require expensive treatment rooms and isolation rooms for radiation protection.
Innovation Solution
A radiotherapy apparatus using a high brightness electron beam emitted through a beam needle, driven by a motion device, that accurately targets tumor lesions with minimal penetration into surrounding tissues, allowing for precise ablation and reduced radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If X-rays are used for radiotherapy, then the radiation can penetrate through the body to reach the tumor, but a lot of energy is accumulated in normal tissues in front of and behind the tumor lesion site causing harm to the body
Solution Approach 1:
The invention segments the radiation delivery system into multiple hollow needles that can be inserted into different regions of the tumor. Each needle delivers radiation independently, allowing precise control over which tissues receive radiation. This segmentation enables the radiation to be confined to the tumor region rather than passing through and damaging normal tissues beyond the tumor.
Solution Approach 2:
The invention applies local quality by using electron beams with specific energy levels (1-10 MeV) that are tailored to reach specific depths corresponding to different tumor locations. The hollow needles are positioned to deliver radiation locally to the tumor site, ensuring that normal tissues in front of and behind the tumor receive minimal or no radiation exposure.
2Object-affected harmful factors
If electron beam radiotherapy is used to minimize harm to normal tissues, then precise targeting is achieved, but the treatment requires expensive equipment and facilities
Solution Approach 1:
The invention extracts the electron beam generation and delivery system from large, expensive radiotherapy facilities and concentrates it into a compact apparatus that can be integrated with the hollow needle system. This extraction allows electron beam therapy to be delivered in a more accessible and cost-effective manner while maintaining the ability to precisely target tumors and minimize harm to normal tissues.
3Reliability
If traditional radiotherapy methods are used, then tumor treatment is achieved, but the treatment causes deep pain to the patient and requires long recovery periods
Solution Approach 1:
The invention uses continuous electron beam delivery through the hollow needles to achieve complete tumor destruction in a single or minimal number of treatments. The electron beam continuously deposits energy in the tumor tissue, ensuring complete ablation without the need for fractionated dosing that extends treatment over multiple sessions, thereby reducing cumulative pain and recovery time.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
The present invention relates to a radiotherapy device. Disclosed are a radiotherapy device and a treatment method which uses the device. The radiotherapy device comprises: an electron beam emission apparatus, which emits an electron beam; a beam needle, which is connected to the electron beam emission apparatus, and causes the electron beam emitted by the electron beam emission apparatus to strike a tumour lesion site within a human body, so as to perform ablation on the tumour; a movement apparatus, which drives the beam needle to perform linear movement, guides the beam needle to the tumour lesion site within the human body, and also guides the beam needle out of the human body after the beam needle has caused the electron beam to strike the tumour lesion site. Compared to the prior art, the present invention accurately kills tumours on organs, does not damage normal tissues, and reduces harm to the human body.
