Automated Anti-Collision Simulation Rod for Gamma Knife
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gamma knife radiotherapy systems require frequent manual installation, adjustment, and removal of anti-collision simulation devices, which is time-consuming and exposes medical staff to radiation, posing health risks.
Innovation Solution
An anti-collision simulation device with a supporting frame and a simulation rod that can be moved relative to a fixed frame, allowing the simulation rod to be positioned at different locations, including a hidden position to avoid interfering with the therapy couch, and incorporating driving devices for automated operation to reduce manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual installation and removal of anti-collision simulation device is performed before each therapy, then collision prevention is achieved, but time consumption increases and radiation exposure to doctors increases
Solution Approach 1:
The simulation rod is made movable through a driving mechanism that enables automatic extension and retraction. The rod can dynamically adjust its position between a simulation position (extending into the therapy cabin) and a retracted position (withdrawing from the therapy cabin), eliminating the need for manual installation and removal while maintaining collision prevention functionality
Solution Approach 2:
The driving mechanism enables the simulation rod to automatically perform its own deployment and retraction operations without requiring manual intervention. The system serves itself by automatically positioning the rod for simulation and then retracting it after use, reducing both time consumption and radiation exposure to medical staff
2Reliability
If simulation rod is extended into therapy cabin for anti-collision simulation, then collision detection is enabled, but interference with therapy couch movement occurs
Solution Approach 1:
The simulation rod is designed with dynamic positioning capability, allowing it to be extended into the therapy cabin only when needed for anti-collision simulation. After simulation completes, the rod automatically retracts to a hidden position that does not interfere with therapy couch movement, enabling both collision detection and smooth couch operation
Solution Approach 2:
The anti-collision simulation is performed in advance before the patient enters the therapy cabin. The simulation rod is extended only during this preliminary simulation phase to detect potential collisions, then retracted before actual therapy begins, ensuring no interference with subsequent therapy couch movement

AI summary
An anti-collision simulation device and a radiotherapy system relate to the technical field of medical equipment. The anti-collision simulation device is applied to a radiotherapy device, and includes a supporting frame and a simulation rod rotatably connected to the supporting frame. A space enclosed by a rotation track of the simulation rod is matched with a space in a therapy cabin of the radiotherapy device. The supporting frame includes a fixing frame and a movable frame. The fixing frame is fixedly installed relative to the radiotherapy device. The simulation rod is rotatably connected to the movable frame, and the movable frame is able to move relative to the fixing frame, so as to enable the simulation rod to be located at different positions.
