Background

A surgical robot is a sophisticated medical device that assists surgeons in performing minimally invasive surgical procedures with enhanced precision, flexibility, and control. These robots are designed to translate a surgeon’s hand movements into smaller, more precise movements of surgical instruments. The most well-known surgical robot is the da Vinci Surgical System, which enables surgeons to operate through tiny incisions using robotic arms equipped with specialized instruments and a high-definition camera.

Motors are the core components of most surgical robots' drive systems, responsible for providing the power source. For surgical robots, there is a demand for both high power density output and compact size and weight to ensure operational freedom in the limited space of the operating room.

During surgical operation, motors in surgical robots generate heat, and poor heat dissipation can lead to temperature-related failures of electronic components, affecting the surgical robot's operational efficiency, and posing surgical risks.

A high-performance liquid cooling system in surgical robots can prevent excessive temperatures from occurring within the robot, ensuring safe operation.

Common liquid cooling methods include circulating flow, immersion, and injection cooling. The most prevalent form for surgical robots is indirect-contact circulating liquid cooling. In circulating flow liquid cooling systems, there are strict requirements for measuring and controlling the coolant.

If the coolant flow rate is too low, it will be unable to dissipate heat promptly; if it is too high, it can lower the temperature excessively and reduce the cooling efficiency of the liquid cooling system, as well as affect the overall performance of the robotic arm.

Addressing These Challenges

1.Precise Measurement of Coolant

The CG series ultrasonic flow sensor  is designed specifically for low flow rate scenarios, maintaining an accuracy of ±3% even when coolant flow rates are below 50 ml/min.

2.Solving Size Challenges

The CG series ultrasonic flow sensors feature an integrated design that is compact and easy to install and remove.

3.Real-Time Measurement and Closed-Loop Control

Sensor flow data is integrated with the robot's temperature control system. Based on the motor temperature and the operation environment, the output coolant of the liquid cooling pump and the motor speed can be adjusted to influence heat control.

4.Electromagnetic Interference

The measurement results are stable and are rarely affected by electromagnetic interference in certain surgical scenarios.

Solving the challenges lead to several critical benefits

Improved Safety

By preventing overheating, CG series ultrasonic flow sensor  contribute to the overall safety of surgical procedures. Surgeons can operate with confidence, knowing that the robotic systems are functioning within safe temperature ranges.

Enhanced Precision

Stable operating conditions allow surgical robots to perform complex procedures with greater precision, reducing the likelihood of complications and improving patient outcomes.

Predictive Maintenance

Continuous monitoring of coolant flow enables predictive maintenance practices. Data collected from CG series ultrasonic flow sensor  can help identify trends, allowing for timely interventions before any issues arise.

By providing accurate, reliable, and contamination-free cooling liquid measurements, CG series ultrasonic flow  sensors play a critical role in thermal management, contributing to improved safety, efficiency, and precision in surgical procedures.
