Enterprise AI Analysis
Use of Multimodal Artificial Intelligence in Surgical Instrument Recognition
This study evaluates the accuracy of publicly available Large Language Models (LLMs)—ChatGPT-4, ChatGPT-40, and Gemini—and a specialized commercial mobile application, Surgical-Instrument Directory (SID 2.0), in identifying surgical instruments from images. While ChatGPT-40 excelled at category-level identification (89.1% accuracy), precise subtype identification remains a challenge for all models. These findings highlight AI's potential in surgical-instrument management and the need for further refinement to enhance patient safety.
Executive Impact
Automating surgical instrument identification offers significant operational efficiencies and enhances patient safety by reducing errors like retained surgical instruments. Integrating AI in perioperative workflows can streamline instrument setup, sterilization, and inventory management, leading to substantial cost reductions and improved resource utilization. While general AI models show promise for basic categorization, specialized solutions are needed for precise identification, offering a scalable path for healthcare institutions to adopt advanced AI technologies.

Overall Performance in Surgical Instrument Category Identification
Performance analysis across all four AI models showed varying capabilities in surgical-instrument identification tasks. For general instrument categories (e.g., “scissors”, “forceps"), ChatGPT-40 achieved the highest accuracy (89.1%), while both SID and ChatGPT-4 demonstrated similar accuracy (77.2% and 76.1%), and Gemini had the lowest accuracy at 44.6%. SID achieved the highest weighted F-1 score (0.84), followed by ChatGPT-4 (0.79) and ChatGPT-40 (0.78), with Gemini showing notably lower performance across all metrics.
Specific Instrument Subtype Classification
In specific instrument-subtype classification (e.g., “Mayo scissors”, “Kelly forceps"), all models showed substantially lower performance. SID achieved the highest accuracy (39.1%), while ChatGPT-40 demonstrated the highest weighted F-1 score (0.39). Both models shared equal weighted precision (0.50), though ChatGPT-4 and Gemini showed markedly lower performance across all metrics. This highlights a critical limitation in current AI systems' ability to make fine-grained distinctions between similar surgical instruments.
Model Performance Insights
Analysis of performance by instrument category reveals distinct patterns and challenges across the four models. The varying accuracy and reliability observed in this study can be attributed to several factors, including dataset quality and diversity, image quality and context (lighting, angle, resolution), and instrument variability. Models trained on larger, more heterogeneous image sets, like SID 2.0's reported millions of images, tend to capture better the nuances of shapes, textures, and reflective properties inherent to surgical instruments. ChatGPT-40's enhanced image-recognition capabilities explain its strong general performance, despite struggling with precise naming.
Practical Applications
Despite performance differentials, all four models share notable advantages: they can be accessed via a simple smartphone application and require minimal hardware, invaluable in resource-limited settings. Deploying an automated instrument recognition tool can enhance patient safety by reducing the risk of Retained Surgical Instruments (RSI). Integrating AI in perioperative workflows can streamline instrument setup, sterilization, and post-operative processing, leading to significant cost reductions and improved efficiency. Multimodal AI, integrating text, images, voice, and other sensor data, can resolve ambiguities and bolster identification tasks, enabling voice-driven queries with real-time validation by a visual AI subsystem.
