Scan-Based Surgical Arm Positioning for Patient-Specific Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons lack access to patient-specific anatomical and procedural information during surgeries, limiting their ability to efficiently plan and execute operations.
Innovation Solution
A teleoperated surgical system with a surgical planning tool that records and annotates surgical procedures, utilizing a database to match patient-specific information and operating room layouts for precise robotic arm and module positioning, and a pattern-matching algorithm to provide relevant surgical data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surgeons rely on generic anatomical models for preoperative study, then the preparation process is simple, but the precision and relevance to patient-specific anatomy is insufficient
Solution Approach 1:
The system creates a digital copy of the patient's actual anatomy by capturing images during surgery and reconstructing a 3D model. This digital replica serves as a precise anatomical reference for preoperative planning, replacing generic models with patient-specific visual data that accurately reflects the individual's unique anatomy.
Solution Approach 2:
The system performs image capture and 3D reconstruction during the surgical procedure itself, creating anatomical reference data that can be used for future procedures on the same patient. This preliminary action during surgery enables more precise preparation for subsequent operations without requiring additional invasive imaging procedures.
2Productivity
If surgeons lack access to patient-specific procedural information, then the surgical workflow is simpler, but the efficiency and outcomes are limited
Solution Approach 1:
The system captures images and video during surgery, then uses this visual feedback to create a record of the procedure and anatomical landmarks. This feedback loop allows surgeons to review actual surgical findings and procedural steps, improving efficiency in future procedures by providing concrete visual reference information about the patient's specific anatomy and surgical approach.
Solution Approach 2:
The system introduces a digital image database as an intermediary between the surgical procedure and the surgeon's decision-making process. This intermediary stores and retrieves visual information about patient anatomy and surgical procedures, enabling efficient access to relevant procedural information without requiring surgeons to rely on memory or generic references.
3Reliability
If no visual record of surgical procedures is maintained, then the system is simpler, but the ability to retrieve relevant information for future procedures is lost
Solution Approach 1:
The system creates digital copies of surgical scenes through image capture during procedures. These visual records are stored in a database, providing a reliable reference for future surgical planning and execution. The digital copies preserve anatomical details and procedural information that can be retrieved and reviewed whenever needed.
Solution Approach 2:
The system extracts key visual information from the surgical procedure and separates it into a dedicated database for storage and retrieval. By taking out only the relevant anatomical and procedural data from the complete surgical video record, the system maintains reliability while managing data complexity efficiently through selective extraction and organized storage.

AI summary
A method is provided for use with a teleoperated surgical system, the method comprising: determining patient position information during a setup for a performance of the surgical procedure within an instance of the surgical system; determining a match between the determined patient position and a patient position signature; and launching a support arm control signal within the surgical system that corresponds to the matched support arm signature.
