DFVision 3D Electronic Laparoscope

DFVision represents MicroPort MedBot’s first product to receive NMPA market approval, achieving registration in June 2021 through the special approval pathway for innovative medical devices. The chip-on-tip 3D electronic laparoscope provides stereoscopic surgical visualization with significantly reduced weight compared to traditional optical laparoscopes.

Product Overview

Entering NMPA’s special approval process for innovative medical devices in 2019, DFVision addresses limitations of conventional laparoscopes by incorporating dual imaging sensors directly at the instrument tip. This chip-on-tip architecture eliminates the weight and complexity of traditional optical relay systems while enabling true 3D visualization for depth perception during minimally invasive surgery.

The system can be used as a standalone 3D laparoscope or integrated with the Toumai surgical robot platform, providing versatile deployment options across surgical settings.

Key Features

DFVision is MicroPort MedBot’s first NMPA-approved product, a dual-sensor 3D laparoscope that places imaging chips at the instrument tip rather than the shaft, cutting weight while delivering dual-HD stereoscopic visualization.

• Chip-on-Tip Design: Dual high-resolution imaging objective lenses positioned at the laparoscope tip, eliminating optical relay systems
• Weight Reduction: Removal of traditional optical structures significantly reduces instrument weight, decreasing operator fatigue
• 3D Stereoscopic Imaging: True depth perception through dual-camera configuration enhances spatial awareness during surgery
• Rich Color Performance: Accurate color reproduction ensures reliable visualization of anatomical structures and tissue differentiation
• Dual HD Resolution: Both imaging channels provide high-definition output for detailed surgical field visualization

Technical Specifications

DFVision’s chip-on-tip dual sensor delivers dual-HD 3D stereoscopic output in a lighter instrument, operable standalone or integrated with the Toumai surgical robot — NMPA approved June 2021, CE certified.

Clinical Applications

DFVision has received NMPA approval for clinical application across multiple surgical departments:

Thoracic Surgery: Lobectomy, segmentectomy, mediastinal procedures General Surgery: Hepatobiliary, colorectal, gastric procedures Gynecology: Hysterectomy, myomectomy, adnexal surgery Urology: Nephrectomy, prostatectomy, bladder procedures

The 3D visualization capability provides particular benefit in procedures requiring precise depth perception, such as dissection around critical structures and suturing in confined spaces.

Regulatory Status

DFVision entered NMPA’s green channel for innovative medical devices, expediting the approval process for this novel imaging technology.

Technology Innovation

The chip-on-tip architecture represents a departure from traditional laparoscope design. Conventional 3D laparoscopes rely on optical systems that transmit images through the instrument shaft to external cameras, adding weight and complexity. By positioning image sensors at the tip, DFVision achieves equivalent visualization capability with reduced mechanical burden.

This design approach aligns with broader industry trends toward distal-tip imaging in endoscopic instruments, offering advantages in maneuverability and integration with robotic platforms.

Market Position

As MicroPort MedBot’s first commercialized product, DFVision established the company’s presence in the surgical imaging market prior to the Toumai robot launch. The product serves both as a standalone solution for facilities seeking 3D laparoscopic capability and as a component of the integrated Toumai surgical system.

Frequently Asked Questions

What is chip-on-tip technology?

Chip-on-tip refers to placing the image sensor directly at the laparoscope tip rather than at the proximal end. This eliminates optical relay lenses, reducing weight and enabling more compact instrument design while maintaining image quality.

Can DFVision be used without the Toumai robot?

Yes, DFVision functions as a standalone 3D laparoscope system for conventional laparoscopic surgery. It can also be integrated with the Toumai robotic platform for robot-assisted procedures.

What advantage does 3D visualization provide?

3D stereoscopic visualization restores depth perception that is lost with conventional 2D laparoscopes. This improves spatial awareness during dissection, suturing, and manipulation of tissues in confined surgical spaces.
