Empowered by High‑Precision Electronics, Changzhou Creation Technologies Helps Upgrade Surgical Robots

In millimeter‑scale dissection in neurosurgery and delicate interventions in cardiovascular procedures, surgeons have long faced a stubborn challenge: traditional surgical robots extend their reach, yet fail to transmit the true tactile feel between instruments and human tissue. Like threading a needle through fog, surgeons rely entirely on visual judgment to estimate force, which inherently raises the risk of tissue damage and intraoperative bleeding.

As minimally invasive surgery advances toward precision and intelligence, force feedback has become a core focus for research teams worldwide. This key technology that gives surgical robots a “sense of touch” is revolutionizing the logic of minimally invasive procedures—and it depends critically on high‑precision electronic manufacturing.

I. Decoding Force Feedback: The Tactile Core of Minimally Invasive Surgery

Force feedback is an intelligent technology that uses sensors to capture interactive forces between instruments and target objects in real time, then converts force signals into physical feedback (pressure, tension, etc.) that surgeons can perceive.

In minimally invasive surgery, it acts as a tactile bridge, allowing operators to accurately sense tissue hardness, pulling tension, and other critical tactile information, even through robotic arms.

Unlike purely visual feedback, force feedback focuses on precise capture and transmission of force signals. Its core value is to eliminate the “tactile blind spot” in surgery, avoiding excessive tissue pulling, accidental vascular injury, and other risks caused by visual bias. It elevates minimally invasive surgery from “seeing clearly” to “operating safely.”

II. The Critical Role of Force Feedback in Minimally Invasive Surgery

The key advantages of minimally invasive surgery include minimal trauma and fast recovery, but the “loss of touch” in traditional surgical robots has long been a major pain point. Force feedback adds decisive value:

• Improves surgical safety: Real‑time force sensing can reduce tissue force during surgery by up to 43%, significantly lowering complications such as bleeding and infection.

• Guarantees operational precision: In neurosurgery, cardiovascular, and other high‑precision procedures, it detects micronewton‑level force changes, ensuring uniform suture tension and gentle dissection.
• Lowers the learning curve: Tactile feedback helps surgeons master techniques faster and shortens proficiency cycles.

III. Global Frontier: Breakthroughs in the da Vinci 5 Force Feedback System

As a global benchmark in surgical robotics, Intuitive Surgical’s da Vinci 5 achieved a milestone in force feedback.

Cleared by the U.S. FDA 510(k) in March 2024, it is the first commercially available surgical robot system with integrated force sensors at the instrument tip approved for wide use in pelvic, thoracic, and other minimally invasive procedures.

Its core breakthroughs:

1. High‑precision sensors integrated at the instrument tip directly capture tissue interaction forces, rather than indirect estimation, for more accurate feedback.
2. Optimized signal transmission and redesigned hand controllers keep end‑to‑end latency below the human tactile threshold, enabling real‑time feedback.
3. Software algorithms synchronize force signals with visual imaging, allowing surgeons to combine tactile and visual judgment.

Pre‑clinical data confirms that force feedback reduces tissue force by up to 43%, providing stronger safety for high‑risk surgeries.

The launch of da Vinci 5 marks force feedback’s shift from research concept to clinical necessity, pushing the global surgical robot industry into the era of “tactile perception.”

IV. China’s Current Status: Catching Up and Breaking Through Core Components

China’s surgical robot industry is growing rapidly, but faces bottlenecks:

• Stability and durability of high‑end force feedback sensors need improvement
• Conventional SMT and coating processes in traditional PCBA manufacturing are insufficient
• Low localization of core electronic components keeps system and consumable costs high

This creates clear opportunities for companies focused on core component innovation.
