Solution Overview

Problem

Existing solutions for holding back tissue during surgery, such as physical holding by assistants, clamps, and frames, are unstable, inconvenient, and labor-intensive, especially when elevating a digit for surgery, as they often require additional stabilization of other digits and can lead to crowding and strain.

Innovation Solution

A frame with two wings and a supporting surface that elevates a digit or digits, featuring engaging features for retaining ties, and a securing device with stretchable ties to stabilize the digit in place, allowing other digits to be held under the frame, providing a stable and ergonomic platform for surgery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a digit is elevated for surgery, then surgical access is improved, but other digits naturally tend to adopt an elevated orientation requiring additional stabilization

Engineering Contradiction:
Improvesurgical accessVSAvoidstabilization requirements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The frame utilizes the weight of other digits (held in a natural position under the plate) as a counterbalancing force to stabilize the elevated digit being operated on, eliminating the need for additional weights or assistants to prevent unwanted digit elevation

Inventive Principle:
Principle #8Anti-weight (Counterweight)

2Stability of the object's composition

If lead weights or assistants are used to hold down digits, then digit stabilization is achieved, but the solution becomes unstable and labor intensive

Engineering Contradiction:
Improvedigit stabilizationVSAvoidsurgical efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The frame is designed to be self-stabilizing through its geometric configuration, where the plate and wings create a stable platform that automatically maintains digit positions without requiring external assistance or adjustment during surgery

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple digits are secured onto the supporting surface, then versatility is improved, but the frame structure becomes more complex

Engineering Contradiction:
Improvedigit accommodationVSAvoidframe structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The supporting surface is designed with a width and geometry that allows it to accommodate either one or two digits depending on surgical requirements, providing multi-functionality without requiring multiple different frame configurations

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention provides a frame (21) for elevating and supporting two digits during surgery. The frame has a plate (24) with two wings (22, 23) which define a plane and a space (25) therebetween, a support surface (32) between the wings to support two digits, and engaging features (28) on each wing for removable engagement with retaining ties to hold digits in place on the frame. The frame provides a platform for securely supporting digits during hand surgery.
