Placement Table Quick-Lock for Precise Radiotherapy Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiotherapy methods, such as photon or electron therapy, cause significant damage to normal tissues due to their physical conditions, and radioresistant tumors are difficult to treat effectively without harming surrounding tissues.
Innovation Solution
A placement table positioning system and method that includes a placement table, a positioning device, a transferring device, and a connecting device with first and second connecting assemblies, allowing for quick and accurate locking of the placement table and positioning device, reducing unnecessary positioning time and irradiation dose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the placement table and positioning device are locked using conventional methods, then the positioning is secure, but the positioning time is excessive and reduces treatment efficiency
Solution Approach 1:
The connecting device is divided into multiple independent connecting assemblies (first connecting assembly on placement table, second connecting assembly on positioning device). Each assembly can be independently engaged or disengaged, allowing parallel locking operations that reduce total positioning time while maintaining secure attachment through multiple connection points
Solution Approach 2:
The connecting assemblies are pre-configured in ready-to-engage positions with alignment features (such as guide rails or positioning pins) that automatically align the first and second connecting assemblies before final locking. This preliminary alignment eliminates time-consuming manual positioning while ensuring accurate engagement, thus reducing positioning time without compromising reliability
2Measurement precision
If simulated positioning is performed separately before treatment, then positioning accuracy is achieved, but additional working time is required
Solution Approach 1:
The simulated positioning function and treatment positioning function are merged into a single integrated process. The placement table positioning device incorporates both simulated positioning capabilities and treatment positioning capabilities, allowing the placement table to be positioned once and used for both simulation and treatment without requiring separate positioning operations, thereby eliminating redundant time while maintaining accuracy
Solution Approach 2:
The placement table positioning device is designed with multi-functionality to serve both simulated positioning and treatment positioning purposes. The same positioning markers, laser positioning system, and connecting device are used in both phases, eliminating the need for separate positioning procedures and reducing overall workflow time while preserving positioning precision

AI summary
A placement platform (40) positioning system, which comprises: a placement platform (40), a placement platform positioning apparatus (60), a placement platform transport apparatus (401), and a connection apparatus (300). Providing the connection apparatus (300) allows the placement platform positioning apparatus (60) to be quickly locked and secured to the placement platform (40), thereby reducing unnecessary positioning steps during treatment. A placement platform (40) positioning method, which comprises: rotating a first connection assembly (500) to a clamping position, such that the first connection assembly (500) and a second connection assembly (700) are locked; moving the placement platform positioning apparatus (60), and positioning the placement platform (40). A locking action between the placement platform positioning apparatus (60) and the placement platform (40) is completed in a single step and the operation is simple and convenient, thereby greatly reducing the overall positioning time of the placement platform (40).
