Solution Overview

Problem

Current sinus surgery methods lack effective access and visualization techniques for inaccessible sinus sites, limiting the ability to perform comprehensive treatments simultaneously with multiple instruments.

Innovation Solution

The method involves creating two separate access openings in the anatomy to allow for the simultaneous introduction and cooperative manipulation of multiple surgical instruments, including endoscopes and laser fibers, to treat inaccessible sinus sites without the need for balloon dilation or guide wires, enabling enhanced visualization and treatment flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single access opening is used for sinus surgery, then the surgical procedure is simpler to perform, but the ability to access inaccessible sinus sites and manipulate multiple instruments simultaneously is limited

Engineering Contradiction:
Improvesurgical procedure simplicityVSAvoidaccess to inaccessible sinus sites
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The single access opening is segmented into multiple separate openings, allowing independent insertion and manipulation of multiple surgical instruments (endoscope, laser fiber, surgical tools) simultaneously at inaccessible sinus sites without instrument interference

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The approach transitions from a single-point access (0D/1D) to multi-point access (2D/3D), enabling instruments to approach the target sinus site from different anatomical dimensions and angles, thereby improving access versatility while maintaining surgical controllability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If balloon dilation or guide wires are used for access, then the sinus passageway can be dilated, but the procedure becomes more complex and time-consuming

Engineering Contradiction:
Improvesinus passageway dilation capabilityVSAvoidprocedure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the need for balloon dilation catheters and guide wires from the surgical procedure, using direct piercing access with surgical instruments instead, thereby reducing device complexity and procedural steps while maintaining the ability to access and treat sinus passageways

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical balloon dilation system is replaced with direct surgical instrumentation through pierced openings, substituting a complex mechanical expansion system with simpler, more direct surgical access and manipulation techniques

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If multiple instruments are introduced through a single opening, then the procedure is less invasive, but the ability to cooperatively manipulate instruments and visualize the sinus site is compromised

Engineering Contradiction:
ImproveinvasivenessVSAvoidinstrument manipulation and visualization
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The single invasive opening is segmented into multiple separate openings, allowing each instrument to be inserted through its own dedicated pathway, thereby eliminating instrument interference and enabling cooperative manipulation while maintaining minimal overall invasiveness through small, targeted openings

Inventive Principle:
Principle #1Segmentation

AI summary

A method for sinus surgery includes piercing first and second access openings into the anatomy of a human subject to access an inaccessible sinus site for cooperatively manipulating respective first and second surgical instruments inserted through the openings. One instrument, for example an endoscope, can permit viewing of the sinus site while the other instrument is manipulated to effect a treatment at the sinus site. The maxillary and other sinuses can be accessed and anti-inflammatory and other treatments can be applied. Systems and instruments for performing such sinus surgery methods are also disclosed.
