A new generation of wearable medical monitors are entering commercialization. HMDmd’s new headset will become available in March 2024 pending FDA approval. The video describes some of the features and development work that characterizes this next generation.
I recently had the chance to check out HMD MD’s new surgical headset at an event hosted by Kopin Corporation, where they celebrated closing the NASDAQ by ringing the bell. This innovative device is now moving toward FDA registration and is expected to become commercially available in March 2024.
I first wrote about this headset three years ago when it was still in its preclinical stage. Since then, the team has worked closely with Kopin to refine the hardware and develop applications with their partners. The progress is impressive. See this article that described the pre-clinical version of the headset. https://www.insightmedia.info/hmdmd-a…
Key Design Highlights
One of the most notable improvements is ergonomics. The headset weighs only 250 grams, making it significantly lighter than competitors like the Apple Vision Pro (around 600 grams) or Leica’s similar headset (also near 600 grams). For surgeons who wear these devices for hours during procedures, this weight reduction is a major advantage.
Another standout feature is excellent peripheral vision. While the headset uses two ocular displays in front of the eyes, it still allows surgeons to see their surroundings—critical for maintaining awareness in the operating room.
Display and Performance Specs
- Resolution: 1080p OLED displays (not LCD as I mistakenly said in my video)
- Compatibility: Supports 4K sources, common in endoscopic and laparoscopic imaging
- Field of View: 35° horizontal
- Pixels per Degree: ~56–57, which defines the limiting resolution
- Modes: Operates in both 2D and 3D
- Refresh Rate: 60 Hz
One of the biggest technical challenges Kopin solved was universal video decoding. Surgical environments use a wide range of imaging sources with different resolutions, frame rates, and encoding structures. The headset can seamlessly handle these variations, ensuring reliable performance.
Applications and FDA Classification
Initial use cases include:
- Neurosurgery
- Ophthalmology
- Endoscopic procedures
- General laparoscopic surgery
The device is classified as an FDA Class I medical device, meaning it does not operate inside the body and is not mission-critical. This classification streamlines regulatory approval and accelerates adoption.
Business Model
HMD MD plans to sell the headset as a smart monitor to system integrators in the medical device field. Production is starting soon, and surgeons will be able to purchase and use these headsets in real surgeries by early next year.
Final Thoughts
With its lightweight design, strong peripheral vision, and universal compatibility, HMD MD’s surgical headset represents a significant step forward in medical wearable technology. It’s exciting to see how this innovation will enhance surgical precision and comfort in the years ahead.
