Device for supporting an operator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical chairs have limited space, leading to a risk of tripping over control switches and accidental misoperation during medical procedures.
Innovation Solution
A device with a platform and a height-adjustable base column, featuring an upper body holding device and actuating units arranged between the seat and platform, allowing foot-operable control of the column and support device, reducing the risk of tripping and misoperation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control switches are arranged on the platform for foot operation, then the operator can control the surgical chair during the operation, but the operator may trip over the control switches when entering the platform and/or accidentally and/or incorrectly operate the control switches during the operation
Solution Approach 1:
The actuating unit is moved from the horizontal plane of the platform to a vertical arrangement between the seat and platform. This dimensional change allows the control function to be separated from the foot placement area, eliminating the tripping hazard while maintaining foot-operated control capability.
Solution Approach 2:
The actuating unit is extracted from the platform surface and repositioned in the space between the seat and platform. This extraction removes the control switches from the area where the operator places their feet, preventing accidental activation and tripping while preserving the foot-operated control function.
2Area of stationary object
If the platform area is limited due to space constraints in the operating room, then the surgical chair can be positioned close to the surgical area, but the control switches occupy valuable foot placement space and cause safety issues
Solution Approach 1:
The control switches are relocated from the horizontal platform surface to a vertical arrangement in the space between the seat and platform. This utilizes previously underutilized vertical space, freeing up the platform surface for its primary function of supporting the operator's feet while maintaining control accessibility.
Solution Approach 2:
The actuating unit is positioned in a specific localized area between the seat and platform that is optimized for foot activation. This local placement ensures that the control function is separated from the general foot placement area on the platform, allowing each zone to serve its intended purpose without interference.

AI summary
The device according to the present disclosure serves to support an operator (surgeon). The device comprises a mobile platform a base column, extending from the platform with a seat an upper body holding device and at least one actuating unit The actuating unit is arranged in an area between a seat surface of the seat and the platform in such a way that the actuating unit can be reached by the surgeon with his foot, so that a surgeon sitting on the seat of the device can easily reach the actuating unit with his foot, in particular with his heel or sole, from any position.
