Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional spinal surgery tables provide limited access to and stabilization of the patient's spine, restricting access to desired surgical procedures and impacting patient-health outcomes.

Innovation Solution

A frame and patient support system with adjustable lower leg, upper leg, pelvic, torso, and head-and-arm supports, allowing for 360-degree rotation and modular integration with surgical table stands, enabling precise patient positioning and access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional spinal surgery tables are used, then the structure is simple and easy to operate, but the access to the patient's spine is limited and stabilization is insufficient

Engineering Contradiction:

Improveaccess to patient's spineVSAvoidtable structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patient support system is divided into multiple independently adjustable segments including head support, torso support, pelvic support, and leg supports. Each segment can be positioned and angled separately to achieve optimal surgical access while maintaining overall structural manageability through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The table incorporates dynamic positioning capabilities with multiple degrees of freedom, allowing each support segment to be adjusted independently in height, angle, and position. This dynamic adjustability enables the system to adapt to various surgical requirements while maintaining patient stabilization.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the patient support structure is simplified for ease of operation, then the device is easier to use, but the ability to manipulate and access the spine is reduced

Engineering Contradiction:

Improvepatient positioningVSAvoidspinal manipulation capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patient support table integrates multiple functions into a single system, combining patient positioning, spinal manipulation, surgical access facilitation, and patient stabilization. The unified control system manages multiple support segments simultaneously, providing comprehensive functionality without requiring separate devices for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If conventional tables with fixed structures are used, then manufacturing is simpler, but access to lateral portions of the patient is limited

Engineering Contradiction:

Improvelateral accessVSAvoidsupport structure

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The support structure incorporates multi-dimensional adjustment capabilities, allowing movement not only vertically but also horizontally and angularly. This enables lateral access to the patient while maintaining structural integrity through coordinated adjustment mechanisms across multiple dimensions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A frame and patient support are provided, as well as surgical methods using the frame and patient support. The frame and patient support can be used to support and manipulate the patient prior to, during, and after surgery to articulate the patient's body to facilitate stabilization of the patient's spine. The frame and patient support can be configured for rotation about a rotational axis, and the frame and patient support can include a lower-leg-support, an upper-leg-support, a pelvic-support, a torso-support, and a head-and-arm support for supporting corresponding portions of the patient's body.
