This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,378.

Summary of the Inventive Concept

This inventive concept presents advanced systems and methods for optimizing the performance of head mounted displays (HMDs) in surgical settings, enhancing the accuracy and efficiency of computer-assisted surgeries.

Background and Problem Solved

The original patent disclosed systems for adjusting and tracking HMDs during surgery, but had limitations in terms of calibration, tracking, and display accuracy. The new inventive concept addresses these limitations by introducing advanced tracking modules, mechanical adjusting mechanisms, and machine learning algorithms to optimize the HMD's position and orientation.

Detailed Description of the Inventive Concept

The new system comprises a surgical helmet with a built-in tracking module, a head mounted display with a detachable mechanical adjusting mechanism, and a sensor module to detect the user's eye movement. The tracking module communicates with the mechanical adjusting mechanism to optimize the display's position and orientation, ensuring accurate visualization of virtual surgical tools and instruments. The system also includes a method for calibrating the HMD using a fiducial marker, and a method for enhancing the accuracy of virtual surgical tools and instruments displayed on the HMD using machine learning algorithms.

Novelty and Inventive Step

The new inventive concept introduces a novel combination of tracking modules, mechanical adjusting mechanisms, and machine learning algorithms to optimize the HMD's performance, which is not disclosed in the original patent. The inventive step lies in the integration of these components to achieve accurate and efficient visualization of virtual surgical tools and instruments.

Alternative Embodiments and Variations

Alternative embodiments may include the use of different types of tracking modules, such as optical or electromagnetic tracking systems. The system could also be adapted for use in other medical procedures, such as endoscopy or laparoscopy. Additionally, the mechanical adjusting mechanism could be replaced with a motorized or robotic system for more precise control.

Potential Commercial Applications and Market

The enhanced systems and methods for adjusting and tracking HMDs during surgery have significant commercial potential in the medical technology industry, particularly in the fields of computer-assisted surgery, surgical navigation, and robotics. The target market includes hospitals, surgical centers, and medical device manufacturers.
