Solution Overview

Problem

Existing orbital floor implant surgeries face inefficiencies due to the wastage of implants during sizing and the need for trimming, leading to increased costs and surgical time.

Innovation Solution

A single-component device functioning as a sizer, introducer, and cutting template made of high-density polyethylene, allowing for precise sizing, introduction, and shaping of orbital floor implants without requiring multiple implants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If an actual implant is used for sizing, then the appropriate implant size can be determined, but the implant may be wasted if not ultimately used

Engineering Contradiction:
Improveimplant sizing accuracyVSAvoidimplant wastage
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The patent uses a sizer device that is a copy or replica of the actual implant, allowing surgeons to determine the appropriate implant size without wasting the actual implant material. The sizer can be removed and discarded after sizing, while the actual implant is preserved for the final procedure.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The sizer is designed as a disposable, low-cost component that can be used for sizing and then discarded. This allows multiple sizing attempts without wasting expensive actual implants, as the sizer can be replaced cheaply if needed.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Measurement precision

If multiple implants are used for sizing, then the appropriate implant size can be determined, but surgery time increases

Engineering Contradiction:
Improveimplant sizing accuracyVSAvoidsurgery time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The sizer allows surgeons to perform sizing actions before the actual implantation procedure. By determining the correct implant size in advance using the sizer, surgeons avoid time-consuming trial-and-error with actual implants during the surgery itself.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Using a copy (sizer) instead of the actual implant for preliminary sizing measurements enables surgeons to make decisions about implant size before the critical implantation phase, thereby reducing overall surgical time.

Inventive Principle:
Principle #26Copying

3Manufacturing precision

If an implant needs to be trimmed for an exact fit, then precision is improved, but additional surgery time and complexity are required

Engineering Contradiction:
Improveimplant fit precisionVSAvoidsurgical process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The sizer can be used to pre-mark and pre-plan the exact contours and dimensions needed for the actual implant. By transferring measurements and markings from the sizer to the actual implant before insertion, surgeons can achieve precise fits without complex intraoperative trimming procedures.

Inventive Principle:
Principle #10Preliminary action
