In 2019, the European Union approved a surgical robot platform originating from Germany. In recent years, there has been no further information on technological iterations or upgrades, such as haptic feedback, remote surgery, or AI-assisted surgery. However, its original design features include several innovations. 1. The mainstream design consists of a surgical table cart with four robotic arms, equipped with a 10mm endoscope, allowing the surgeon to observe a 3D high-definition surgical field through an eyepiece. The open control console facilitates normal communication with the surgical team. The control console integrates a seating adjustment device and control handles, reducing fatigue caused by long surgeries. 2. The most significant innovation is the design of disposable sterile instruments. Utilizing 7 degrees of freedom with 5mm disposable instruments, this strategy reduces the risk of cross-infection compared to the sterilization and maintenance of reusable instruments, while also alleviating the long-term operational burden. The disposable sterile instruments represent a beneficial attempt to address the high cost of consumables in surgical robots. The disposable nature inherently leads to a shorter development cycle and lower R&D costs, allowing for faster updates and iterations. For highly complex and miniaturized surgical instruments, such as articulated instruments and those equipped with micro-sensors, the reprocessing process is extremely complex, difficult, and costly. Disposable sterile instruments fundamentally eliminate the risk of cross-infection and avoid surgical risks due to instrument wear, damage, or inadequate cleaning. The design of disposable sterile instruments primarily focuses on meeting the functional requirements of single-use surgeries, simplifying the design structure without the need to consider durability and reusability. The materials and processes are also simpler. Additionally, the interface and connection design with the surgical robot system are more straightforward, requiring only a single effective connection and use, which can adopt standardized and simplified designs for quick installation and disassembly. In the current healthcare environment, where cost control is paramount and there are low or even no charge items, the low-cost approach of disposable sterile instrument design is a beneficial attempt to improve the dilemma of surgical robots being affordable but not usable.
