Wearable Interface for Laparoscopic Endoscope Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interfaces for laparoscopic surgery, such as those using head-mounted light sources, voice-operated systems, or directional key interfaces, divert the surgeon's focus from the primary task and fail to clearly indicate which instrument they are attending to, leading to difficulties in maintaining a stable endoscope view and efficient surgical procedure.
Innovation Solution
A wearable interface system with wireless transmitters and receivers that allow the surgeon to select and focus the endoscope on specific instruments using a visual depiction on a screen, enabling seamless communication between the surgeon and automated assistants, and allowing the endoscope to be directed automatically to the selected instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional interfaces (head-mounted light sources, voice-operated systems, directional key interfaces) are used to control the endoscope, then the surgeon can direct the endoscope to different locations, but the surgeon's focus is diverted from the primary surgical task and the interface becomes cumbersome requiring constant attention
Solution Approach 1:
The system automatically tracks and identifies the instrument the surgeon is attending to using image processing and pattern recognition algorithms. The automated assistant independently determines which instrument requires endoscope focus based on visual analysis of the surgical field, eliminating the need for manual directional commands from the surgeon.
Solution Approach 2:
The patent replaces manual mechanical control interfaces (directional keys, voice commands, head movements) with an automated visual recognition system. The system uses computer vision to detect instrument positions and surgeon attention, substituting the mechanical interaction interface with an intelligent automated decision-making system.
2Measurement precision
If automated assistants are used to maneuver the endoscope, then the endoscope can be directed to specific locations, but the system fails to clearly indicate which instrument the surgeon is attending to
Solution Approach 1:
The system continuously monitors the surgical field using the endoscope camera and provides real-time feedback about instrument positions and surgeon attention. The automated assistant receives ongoing visual information and adjusts the endoscope positioning based on the detected instrument of interest, creating a closed-loop feedback system that maintains accurate focus on the relevant instrument.
Solution Approach 2:
The system uses visual cues and color-coded indicators on the display to highlight the identified instrument of interest. The interface presents visual information about which instrument the surgeon is attending to, using color changes and graphical overlays to communicate instrument identification status to the surgical team.
3Adaptability or versatility
If manual assistants are used to hold and shift the endoscope, then the endoscope position can be adjusted, but it is difficult to maintain a stable upright view
Solution Approach 1:
The patent replaces manual mechanical holding and positioning of the endoscope by human assistants with an automated robotic assistant. The automated system uses computer vision and control algorithms to maintain stable, upright positioning of the endoscope, eliminating the instability and variability inherent in manual holding.
Solution Approach 2:
The automated assistant independently maintains endoscope positioning and stability without requiring continuous manual adjustment. The system self-corrects positioning errors and maintains optimal viewing angles automatically, providing stable images without human intervention.
