The system consists of a "physician end" and a "patient end." The physician end comprises an "ultrasound-shaped handle" and a "human-body force feedback operating platform," while the patient end is the ultrasound robot itself. In practice, physicians can remotely control the patient-end robot, replicating scanning techniques at a 1:1 ratio and combining real-time audio-video technology to perform remote ultrasound scans. Meanwhile, physicians can conduct immediate medical diagnosis through ultrasound images transmitted in real time.
Application scenarios for the Ultrasound Probe Holding and Remote Control System
01
Remote Ultrasound Robot Approved for Market Industry-Leading Product Performance
Hebin Intelligent's "Ultrasound Probe Holding and Remote Control System" distinguishes itself through four core strengths: flexibility, universality, intelligence, and safety. These characteristics are embedded in both the physician and patient ends, improving scanning efficiency while ensuring patient safety.
First, from the physician-end perspective: its portable design makes remote control of the ultrasound robot more intuitive and expands the contexts in which physicians can use it. The shaped handle connects via USB and is compatible with various laptops and desktop hosts, accommodating diverse physician needs.

Ultrasound Probe Holding and Remote Control System — Physician End
Second, the physician end employs an active operational safety strategy that can distinguish the physician's operational intent in real time, eliminating remote misoperations and comprehensively protecting patient safety. Meanwhile, the "ultrasound probe-shaped handle" allows physicians to quickly adapt to the master control interface. The accompanying "human-body biomimetic force feedback operating platform," made from biomimetic soft materials, accurately simulates the curvature and stiffness of human skin, providing physicians with a realistic scanning experience.

Ultrasound Probe Holding and Remote Control System — Patient End
From the patient-end perspective, Hebin Intelligent's ultrasound robot innovatively employs a 7-degree-of-freedom (7-DOF) robotic arm structure. Compared with conventional 6-DOF arms, it adds one degree of freedom and multiple force sensors, ensuring operational flexibility and high end-effector reachability. Traditional 6-DOF arms have only one arm configuration to reach a scanning point; when joint limits or obstacles block the path, the scanning task fails. The 7-DOF arm moves with greater flexibility and freedom, satisfying various operational requirements in clinical testing.
Additionally, the robotic arm incorporates multiple high-sensitivity force perception sensors, using AI-powered mechanical control for full-machine anomaly detection and prevention, providing patients with a more comfortable scanning experience. Aerospace-grade precision teleoperation control technology ensures reliable, safe remote control and accurate reproduction of the physician's technique.
Finally, the patient end adopts a layered safety control strategy, with active safety measures at the perception layer, impedance control layer, and human-machine interaction layer, implementing hierarchical safety control to ensure the security of robotic scanning.

Currently, amid the broader trend of medical-engineering integration, the unification of industry, academia, research, and medicine has become an important goal in China's medical sector. To develop more technologically advanced, high-performance remote ultrasound robots, continuous collaboration across these domains is essential.
To this end, Hebin Intelligent has established partnerships with multiple domestic universities, research institutions, and medical organizations, engaging in source innovation from both underlying technology and actual clinical needs.
Clinical trials
All technological advancement serves clinical application. From a clinical standpoint, launching new products and technologies must begin with identifying needs — needs create markets and products, and drive innovation for the market. This holds especially true in healthcare.
Hebin Intelligent co-founder Qi Huang stated: "From the very beginning of product development, we started from actual clinical needs and created a progressive intelligent ultrasound solution. Through the remote ultrasound robot, we can collect and quantify physicians' technique data, breaking the spatial and temporal barriers between doctors and patients. After learning and quantifying physician techniques, through iterative development, we enable the robot to perform autonomous ultrasound scanning. Combined with artificial intelligence, this makes scanning more standardized, regulated, and accurate."
