Moving digital medical device into the operating room has become a key advancement in the dramatic advancement of surgery.
Caduceus S
Augmented Reality Computer Surgical Navigation System
Since 2013, Dr. Min-Liang Wang has been dedicated to academic research in augmented reality (AR) for spine surgery. His early work in this field garnered significant recognition, including being featured on" Discovery Channel ". Based on these research findings, Dr. Min-Liang Wang founded SURGLASSES in the Taichung Science Park, Taiwan in 2017 and assumed the role of CEO.
FDA 510(k) clearance
SURGLASSES has become a leading developer of Augmented Reality headset for spine surgery and has established a U.S. subsidiary, SURGLASSES, LLC, based in Rancho Cucamonga, California. Our flagship product, the Caduceus S AR Spinal Surgery Navigation System, represents a major technological breakthrough. Unlike traditional systems that require multiple imaging devices, Caduceus S uses a single C-arm for AR navigation, significantly reducing the need for additional preoperative or intraoperative CT scans, thereby minimizing radiation exposure for patients.
Caduceus S has received FDA 510(k) clearance in the United States, as well as regulatory approvals from TFDA and the Thailand FDA as a Class II medical device.
Driven by a passion for innovation and patient care, the diverse team at SURGLASSES is dedicated to developing cutting-edge medical devices. Our vision is to assist more patients through the power of technology, continuously transforming the landscape of surgical precision and patient outcomes. Subscribe to our channel to stay updated on the future of AR in surgery.
Our advantage
Pioneering AR Spine Surgery Navigation System, Accredited with TFDA Class II Medical Device License:
Ministry of Health Medical Devices No. 007161 （TFDA）
Ministry of Health Medical Devices No. 007725 （TFDA）
Ultra low radiation
AR surgery starts with just an initial 2 to 4 x-rays.
Real-time projection of augmented reality (AR).
Project the real-time AR augmented reality of the surgical navigation screen in front of the doctor's eyes, focusing on the affected part.
Ultra-precise surgical positioning
Just like the GPS positioning and navigation of the human body, it accurately locates the distance, direction, and angle of the lesion with an error of less than 2mm.
Minimally invasive surgery
Assisting in minimally invasive surgery, the wound is greatly reduced and the amount of bleeding is reduced.
Caduceus S
In order to reduce damage to normal tissues, doctors need to perform complex spinal surgery in a narrow field of view and limited operating space. Therefore, it is even more necessary to use the guidance of the navigation system to directly reach the lesion. The real-time AR projection of the navigation screen presents the information in the patient's body in front of the doctor's eyes allowing doctors to focus on the surgical area of the patient, improving the safety and accuracy of minimally invasive surgery.
Augmented Reality Surgery Features – Focus on FOV
AR Augmented Reality Surgery Features – Focus on FOV Although there are devices on the market for spinal surgical navigation for conventional and minimally invasive pedicle screw placement, there are still some inherent difficulties with conventional navigation systems in terms of ergonomics and efficiency of integration with the surgeon's workflow. Traditional two-dimensional (2D) spinal navigation requires taking the focus from the FOV away to observe the image data on an external display screen, then translating it to the instruments being operated on during surgery and tactilely identifying the three-dimensional (3D) position. The disruption of this shift in vision and the inevitable shift in attention has had an impact on the cognitive load and workflow optimization during surgery.
Caduceus S AR extends the benefit of navigation system realistically
According to the restrictions of local authority, the radiation dose received by the general public in a year shall not exceed 5 millisieverts, while the radiation dose of a computerized tomography scan is about 1.5-2 millisieverts1, especially for patients who need to undergo surgery. Pay more attention to radiation protection.
| AR Augmented Reality Navigation System Caduceus S AR | Other spine navigation systems | Traditional Open Spine Surgery | |
|---|---|---|---|
| Look up times | No need | Frequently | Frequently |
| Setup time for navigation device. | About 10 minutes | About 30-40 minutes | Not applicable |
| Radiation dose | Only need to take about 2~4 images | Extensive X-rays are required for confirmation | Extensive X-rays are required for confirmation |
| Preoperative CT | No need | CT before surgery is required | No need |
| Operation time | About 2-4 hours | About 3-5 hours | About 3-5 hours |
| The number of days in hospital | About 2-4 days | About 2-4 days | About 7-10 days |
| Postoperative rehabilitation | Within about a month | Within about a month | About 2-3 months |
| Wound size | Small, about 2-3 cm (single segment) | Small, about 2-3 cm (single segment) | Large, about 5-10 cm (single segment) |
Radiation Exposure Carcinogenic Risk
Ultra Low Mode
A large amount of radiation exposure will seriously affect the health of the human body. The resulting radiation damage will increase the risk of leukemia, and the removal of bone marrow will affect the hematopoietic function. Spine surgery glasses navigation system provides ultra-low radiation mode, no need to take computerized tomography (CT) that will produce high radiation, just take 2 to 4 X-rays before the operation starts to affect the positioning and start the operation, no need during the operation Taking X-ray images again greatly reduces the risk of radiation exposure for patients and medical staff.
AR glasses enable real-time projection.
While focusing on the patient's affected part, the doctor can also navigate and position the AR surgical glasses directly in front of his eyes, without frequently looking up or turning his head to check the external screen, which would be distracted by the environment and interrupt the workflow
Quick to adapt
It can be used without too many changes, allowing medical staff to adapt quickly. There is no need to change the original environmental equipment.
