Separable Operating Table for Proton Beam Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional therapeutic beds lack a mechanism to securely position patients for proton beam radiation therapy, leading to difficulties in performing radiation therapy without affecting non-target sites and inutilizing data from examinations like MRI and CT for proton beam treatment.
Innovation Solution
An operating table with patient placement securing means, a main body, coupling means, and rotatable drive control means that securely positions patients and allows for precise rotation and separation of the patient placement securing means from the main body, enabling effective proton beam radiation therapy while maintaining accurate posture and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the base frame and platform are integrated in conventional therapeutic beds, then the structure is simple, but the device size becomes large and cannot be easily moved for MRI and CT examinations
Solution Approach 1:
The operating table is divided into separable components: the base frame (3) and the patient placement table (2) can be detached from each other. This segmentation allows the patient placement table to be removed for MRI and CT examinations while the base frame remains, resolving the contradiction between structural simplicity and mobility for examinations.
2Device complexity
If conventional therapeutic beds lack a securing mechanism, then the device is simple, but the patient cannot be securely positioned for proton beam radiation therapy
Solution Approach 1:
The patient placement table (2) is pre-equipped with securing means (12) that can be activated before proton beam radiation therapy. This preliminary preparation of positioning and securing mechanisms ensures reliable patient positioning without requiring complex additional devices, resolving the contradiction between device simplicity and positioning reliability.
3Stability of the object's composition
If the patient placement table cannot be separated from the main body, then the structure is stable, but examination data cannot be utilized for proton beam treatment
Solution Approach 1:
The coupling between the patient placement table (2) and base frame (3) is made dynamic rather than fixed. The table can be attached when stability is needed for treatment and detached when mobility for examinations is required. This dynamic configurability resolves the contradiction between structural stability and adaptability for examination integration.

AI summary
Problem To provide an operating table that eases radiation therapy with proton beam without adversely affecting sites other than a lesion. Additionally, information on the lesion site specified by a survey instrument is usable for the radiation with proton beam as it is. Thus, the operating table ensures effective treatment with proton beam. Solution An operating table (1) includes a patient placement table (patient placement securing means) (2), a main body (3), engaging pieces (coupling means) (4, 4), and so on, and a motor (rotatable drive control means) (14). The patient placement table (2) is to place and secure a patient P in a required posture. The main body (3) supports the patient placement table (2). The engaging pieces (4, 4), and so on removably couple the patient placement table (2) to the main body (3). The motor (14) rotates the patient placement table (2) with a head-feet direction of the patient as a rotation axis to hold the patient placement table (2) at any given rotation angle. The patient placement table (2) and the main body (3) are separatable as necessary.
