Surveillance Marker for Robotic Surgery DRB Dislodgment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current robotic-assisted surgical systems face challenges in accurately detecting the dislodgment of a dynamic reference base (DRB) during procedures, which requires reinitialization of registration processes, and existing surveillance markers often require additional incisions and rigid interfaces with the DRB, complicating their application.

Innovation Solution

A surveillance marker system that does not rigidly interface with the DRB, allowing it to be attached to a post separate from the DRB, with a temporary grouping element for initial attachment and independent positioning, enabling detection of DRB dislodgment without additional incisions and maintaining accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a surveillance marker is rigidly attached to the DRB, then detection of DRB dislodgment is improved, but device complexity and surgical procedure complexity worsen due to requiring additional incisions and rigid interface structures

Engineering Contradiction:

Improvedetection of DRB dislodgmentVSAvoidattachment structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The surveillance marker is extracted from the DRB structure and positioned independently on the bone surface, eliminating the need for rigid attachment mechanisms while maintaining dislodgment detection capability through separate tracking of both the DRB and marker positions

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A separate tracking system acts as an intermediary to monitor the position of both the DRB and surveillance marker independently, allowing detection of relative displacement without requiring physical connection between the marker and DRB

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a surveillance marker is attached to the patient, then detection of DRB dislodgment is improved, but loss of time worsens due to requiring additional incisions and setup procedures

Engineering Contradiction:

Improvedetection of DRB dislodgmentVSAvoidsurgical setup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The surveillance marker attachment procedure is merged with the existing DRB placement procedure, allowing both to be positioned during the same surgical setup phase without requiring separate incisions or additional time-consuming attachment steps

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The surveillance marker serves multiple functions: it acts as a dislodgment detection reference point and can be positioned using the same surgical access as the DRB, making the system versatile and time-efficient

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If the surveillance marker is positioned independently from the DRB, then ease of operation is improved, but measurement precision may worsen due to potential relative movement between marker and DRB

Engineering Contradiction:

Improvemarker attachment simplicityVSAvoidposition tracking accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system continuously monitors the relative position between the independently positioned surveillance marker and the DRB, providing feedback that allows real-time detection of any dislodgment while maintaining measurement precision through active position verification

Inventive Principle:

Principle #23Feedback
