Surgical imaging device for minimally invasive surgery

This technology is an insertable medical imaging device with stereoscopic viewing for single-port surgery.

Unmet Need: Imaging instrument for single-port surgery

Although surgical practice has evolved to prioritize reducing patient trauma and improving surgical efficiency, visualization technology remains a challenge. Conventional laparoscopes are rigid and have limited maneuverability, making it difficult to achieve optimal viewing angles during complex surgery. These systems also need to be repositioned throughout the procedure and occupy port space. This reduces access points for other surgical instruments, often leading to additional incisions.

The Technology: Fully insertable imaging device for minimally invasive surgery

This technology is a small, flexible imaging device designed to be fully inserted into the body during surgery. It features a modular camera and lens system that enables stereoscopic visualization, providing better depth perception with pan, zoom, and tilt controls. Because it is fully internal, it frees up surgical port space for additional tooling. Minimizing the need for additional incisions reduces patient trauma and allows for single-port surgery.

Applications:

• Single-port minimally invasive surgery
• Robotic surgery
• Examination of anatomically complex spaces
• Stable internal visualization

Advantages:

• Compact, enabling full insertion into the body
• Multiple degrees of freedom on the camera
• Modular camera, lens, and integrated lighting system
• Frees up insertion port for additional tools
