Eye Marker Device with Electronic Positional Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for marking the eye to correct astigmatism are inefficient due to the short-lived nature of ink marks from metal markers, which are often inaccurate and require the patient to be marked in a specific position just before surgery, causing delays and inaccuracies in astigmatism correction.
Innovation Solution
An eye marker device with a pre-inked, sterile, and optionally disposable tip, equipped with an automatic electronic positional detection system, including a servo motor, accelerometer, level sensor, and LED, to accurately mark the eye with lasting ink marks, allowing for preoperative marking and improved patient flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If metal markers with thin ink layer are used to mark the eye, then the marking process is simple and quick, but the ink marks are short-lived and blinked off within minutes
Solution Approach 1:
The patent changes the physical parameters of the marking system by using a metal marker with a porous surface structure and applying multiple layers of ink, transforming the thin single-layer ink application into a multi-layer saturated marking system that resists blinking
Solution Approach 2:
The patent applies preliminary action by marking the eye with reference marks before the patient enters the operating room, allowing time for the marks to set and last throughout the surgical procedure, rather than marking immediately before surgery
2Measurement precision
If the patient is marked in the sitting position just before surgery, then the marks are accurate for astigmatism correction, but it delays the normal prep sequence and reduces patient flow efficiency
Solution Approach 1:
The patent performs the marking action in advance in the preoperative area before the patient enters the operating room, eliminating the need to delay the surgical prep sequence. The marks are applied while the patient is sitting and then allowed to set during transport to the operating room
Solution Approach 2:
The patent uses a disposable pre-inked marker that can be applied in advance, replacing the need for time-consuming intraoperative marking procedures and allowing continuous patient flow through the operating room
3Productivity
If surgical markers are applied in the preoperative area, then patient flow is improved and marking is done in advance, but the ink marks are not lasting enough compared to those applied with sterile metal markers in the operating room
Solution Approach 1:
The patent changes the marker parameters by using a metal marker with porous surface properties and applying ink in multiple layers to create a saturated, durable mark that lasts throughout the surgical procedure even when applied in advance
Solution Approach 2:
The patent applies marks in advance in the preoperative area with sufficient time for the ink to set and adhere to the ocular surface, allowing the marks to be durable throughout the surgical procedure without requiring intraoperative application
