Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing surgical frames require manual manipulation of patients, leading to unnecessary stress and torsion during transfer between surgical tables and frames, which can compromise patient safety and surgical access.

Innovation Solution

A surgical frame with a main beam that can be rotated, raised, lowered, and tilted to facilitate the transfer of patients from and to a surgical table/gurney, minimizing manual handling and reducing stress on the patient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If manual manipulation is used to position patients on surgical frames, then the transfer process is simple and direct, but the patient is subjected to unnecessary stress and torsion

Engineering Contradiction:

Improvestress and torsion on patientVSAvoidmanual patient positioning

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical manipulation with an automated mechanical system. The surgical frame includes a main beam that can be automatically positioned and a patient support surface that can be transferred mechanically, eliminating the need for manual patient handling and thereby reducing stress and torsion on the patient during transfer.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary patient support surface that acts as a mediator between the surgical table and the surgical frame. This support surface allows the patient to be transferred as a unit rather than being manually manipulated, reducing harmful forces while facilitating the transfer process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the main beam is made movable with multiple degrees of freedom, then patient transfer is facilitated and surgical access is improved, but the device complexity increases

Engineering Contradiction:

Improvemain beam positioning flexibilityVSAvoidsurgical frame structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic main beam structure that can move in multiple degrees of freedom including rotation about a vertical axis, elevation changes, and tilting. This dynamic capability allows the main beam to adapt to different surgical positions and facilitate patient transfer, while the movements are coordinated through a control system that manages the complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The main beam is designed as a multi-functional component that performs multiple functions: supporting the patient, facilitating transfer through movement, providing surgical access through positioning, and enabling various surgical approaches through rotation and tilting. This universality justifies the increased complexity by consolidating multiple functions into a single integrated structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A surgical frame and a method for use thereof facilitates transfer of a patient from and to a surgical table/gurney. The surgical table includes a main beam positionable such that a surgical table/gurney with patient laying thereon can be positioned under the main beam. The main beam includes componentry for supporting a patent thereon, and the main beam can be rotated, raised/lowered, and tilted upwardly/downwardly to afford positioning and repositioning of the main beam to facilitate transfer of a patient from the surgical table/gurney to the main beam and transfer from the main beam to the surgical table/gurney.
