Solution Overview

Problem

Existing endoscopic surgical systems for minimally-invasive spinal procedures are often difficult and cumbersome to use, hindering precise visualization and efficient operation during surgical procedures.

Innovation Solution

An access system comprising a rotatable adaptor with projections and openings that align for secure mounting to an access portal, allowing for adjustable positioning of a viewing device to enhance visualization, including a holder for the viewing device that can be moved and rotated to optimize the surgical site view.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If endoscopic devices are used to enable minimally-invasive surgical procedures with improved visualization, then visualization quality is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improvevisualization qualityVSAvoiddevice complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The adaptor is designed to be compatible with multiple types of endoscopic viewing devices while providing a unified mounting interface. The holder can accommodate different endoscope sizes and configurations, allowing a single adaptor design to serve multiple functions and reduce overall system complexity.

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

Solution Approach 2:

The holder is designed to nest within the adaptor structure, with the viewing device then nesting within the holder. This nested arrangement consolidates multiple components into a compact integrated unit that reduces spatial requirements and simplifies the overall device architecture.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Illumination intensity

If endoscopic devices are used to enable minimally-invasive surgical procedures with improved visualization, then visualization quality is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvevisualization qualityVSAvoidease of operation
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The holder is designed with movable and adjustable components that allow dynamic positioning of the viewing device during surgical procedures. The adaptor can be rotated and adjusted to optimize the viewing angle, providing operational flexibility without requiring complex reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adaptor and holder are pre-configured with alignment features and mounting mechanisms that simplify the attachment process. The projections and openings are pre-positioned to guide correct alignment, reducing the time and complexity of setup before surgery begins.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If projections and openings are designed to align for secure mounting, then reliability of attachment is improved, but device complexity increases

Engineering Contradiction:
Improveattachment reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The projections on the adaptor are designed with asymmetric positioning and shapes that correspond to matching asymmetric openings in the holder. This asymmetric design provides inherent alignment guidance and ensures secure mounting in a specific orientation, while the simplicity of the asymmetric features keeps the overall design straightforward.

Inventive Principle:
Principle #4Asymmetry

AI summary

An access system is provided for establishing an access path to a surgical site within a patient. The access system comprises an access portal defining a working channel with a central axis, and an adaptor with a mating section mountable to the access portal. The adaptor is selectively rotatable about the central axis. The access portal includes a plurality of openings and the adaptor includes a plurality of projections, each of the projections and openings being arranged so that, in a first orientation, the openings and projections align to allow mounting of the adaptor to the access portal and, in a second orientation, the openings and projections do not align to prevent disassociation between the adaptor and the access portal. The adaptor also includes a holder for a viewing device, the viewing device being movable with the adaptor about the access portal and vertically translatable relative to the access portal.
