Medical Tool Insertion Signature Detection for Installation Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing minimally invasive medical procedures face challenges in properly installing and recognizing medical instruments, which can lead to safety issues and inefficiencies due to the lack of effective systems for detecting and recognizing tool presence, type, and characteristics.
Innovation Solution
A tool recognition assembly is provided with a first reader and target, capable of detecting the presence or absence of targets during installation, and generating an insertion signature for comparison with model signatures, ensuring proper installation and recognition of medical instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual installation and recognition of medical instruments is used, then device complexity is reduced, but reliability and safety are compromised due to potential installation errors and inability to verify proper installation
Solution Approach 1:
The patent applies preliminary action by pre-configuring targets on the medical instrument and readers in the tool recognition assembly before installation. The targets are positioned at specific locations on the instrument, and readers are placed at corresponding locations in the assembly, enabling automatic detection and verification of proper installation without requiring manual configuration during the installation process.
Solution Approach 2:
The patent uses targets and readers as intermediary elements to mediate between the medical instrument and the control system. The targets on the instrument interact with the readers in the tool recognition assembly, creating an intermediary detection mechanism that provides installation verification information to the control system without requiring direct complex communication between the instrument and control system.
2Object-affected harmful factors
If no tool recognition system is implemented, then ease of operation is improved by simplifying the installation process, but harmful factors increase due to potential patient injury from improper tool installation
Solution Approach 1:
The patent implements feedback by having the control system receive detection information from the readers, compare it against expected patterns, and provide feedback regarding proper installation. The system can indicate whether the medical instrument is properly installed, oriented, and authenticated, providing immediate feedback to the operator to prevent harmful outcomes from improper installation.
Solution Approach 2:
The system performs preliminary verification of tool installation and authenticity before allowing operation, preventing harmful factors by ensuring proper installation is confirmed in advance. The control system checks the detection information against expected patterns before enabling instrument operation, thereby preventing patient injury from improper tool installation.
3Measurement precision
If automatic tool recognition with multiple readers and targets is implemented, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the detection function into multiple readers positioned at different locations in the tool recognition assembly, each detecting targets at specific positions on the medical instrument. This segmentation allows precise determination of instrument installation status by analyzing which readers detect which targets, providing high measurement precision through distributed detection points.
Data Source
AI summary
A system comprises a tool including a first target, a receiving member configured to receive the tool, and a first reader positioned along the receiving member. The first reader is configured to detect a presence indication of the first target of the tool when the first target is proximate the first reader as the tool is inserted into the receiving member and an absence indication of the first target of the tool when the first target is out of range of the first reader as the tool is inserted into the receiving member. The system further comprises a control system communicatively linked to the first reader. The control system is configured to receive one or more of the presence and absence indications of the first target from the first reader to create a detected insertion signature of the received tool.
