Project Brief

Fundus surgery, which frequently entails the injection of therapeutic agents via the retina or blood vessels, as well as membrane peeling procedures, necessitates a level of operational precision that often exceeds human capabilities due to the minuscule target tissues involved. In light of this challenge, Oculotronics Medical has developed a robotic system designed to assist or potentially replace surgeons during these procedures.

This system equips the surgical robot with advanced sensing and operational capabilities through a flexible operating mechanism and a sophisticated sensing controller. Furthermore, the integration of computer-based intelligent recognition and automation technologies facilitates remote operations and enables the transfer of surgical skill sets. The overall design emphasizes not only technological advancement but also prioritizes user-friendliness, compatibility, and hygiene, thereby ensuring that healthcare professionals can perform surgeries efficiently and safely.

Project Innovation/Need

Formal Innovation: The product design adheres to the concept of "simplicity with sophistication," ensuring that the exterior aligns with the design principles of conventional medical equipment. This approach facilitates users' intuitive understanding of its functions and operational methods. Additionally, the overall shape of the product has been engineered to cooperate with various types of medical equipment, thereby preventing any operational range conflicts and ensuring seamless and convenient functionality.

Functional Innovation: The product integrates key functionalities such as robot-assisted surgery, pre-operative planning, and intra-operative positioning and navigation. This integration enables the micro-injection of pharmaceuticals and enhances operational visualization, which, in turn, improves surgical success rates. Furthermore, the surgical robot controller proportionally maps the surgeon's hand movements, achieving exceptionally high precision in control.

Safety Innovation: The product incorporates multiple safety features, including software prompts, indicator lights located on the top of the device, emergency exit mechanisms, and emergency stop switches. These measures are designed to effectively prevent and respond to errors and emergencies that may occur during the surgical procedure.

Design Challenge

Precision Control: The size of the eye is inherently tiny, necessitating an exceptionally high level of precision in control. The surgical robot's controller translates the surgeon's hand movements into the operative field with a ratio of 1:100 or greater. Specifically, a movement of 1 centimetre at the controller corresponds to an intraocular displacement as minimal as 0.01 mm. This remarkable precision significantly enhances the success rate of surgical procedures through refined manipulation.

Stability: For ophthalmic microsurgery, the robotic system is required to possess superior stability and an end-effector mechanism that can filter out physiological tremors inherent to human manipulation. This capability ensures minimal incision trauma, enhancing the surgical procedure's overall safety and precision.

Convenient Operation: Traditional fundus surgeries demand extensive hands-on experience due to their advanced procedural complexity, resulting in a limited availability of qualified practitioners. This robotic system enables surgeons to acquire proficiency more rapidly, addressing the challenges of limited medical resources.

Sustainability

The product features a modular design, allowing for the disassembly and classification of all components for recycling purposes. Recyclable materials, including metal and ABS plastic, are incorporated to enhance resource utilization efficiency. Furthermore, the application of a dense oxygen isolation layer and a metal paint coating significantly improves the product's resistance to corrosion and abrasion, thereby extending its operational lifespan and minimizing resource wastage associated with the frequent replacement of equipment.

Additionally, the product system can be integrated with remote control technology and ultra-high-definition microscopic stereoscopic visual imaging technology. This integration facilitates the optimization of the global distribution of ophthalmic medical resources, reducing both time and economic costs for healthcare providers and patients. It also enables the remote teaching of surgical techniques, thereby advancing the dissemination and development of ophthalmic medical techniques.
