What Are The Application Cases of Trapezoidal Screw in Medical Equipment?

Lead screws are widely used in medical devices. Here are some examples:

1. Long-Actuation Mechanism for Interventional Devices: 

This innovative mechanism integrates a trapezoidal nut, elongated interventional instrument, and lead screw. By coiling the instrument around the screw, the system achieves long-distance linear delivery with enhanced anti-slip performance. The compact design makes it ideal for guiding guidewires, catheters, and other slender interventional instruments in minimally invasive procedures.

2. Medical Imaging Equipment: 

In medical imaging devices such as CT scanners and MRI systems, trapezoidal lead screws are used for elevating the scanning table. Their low-friction characteristics and smooth operation ensure quiet operation while maintaining precise and stable table elevation, thereby guaranteeing patient comfort during scans and maintaining image accuracy.

3. Injection Pump: 

As a critical medical device, injection pumps require high torque density and operational efficiency in their design. The application of electric lead screws in these pumps enhances pressure output, reduces equipment footprint, and ensures precise liquid dispensing. By precisely controlling the rotation angle and speed of the lead screw mechanism, the system achieves accurate regulation of both the dosage and delivery rate of pharmaceutical solutions.

4. Medical Device Specialized Lifting Mechanism: 

This specialized lifting mechanism employs a single-head trapezoidal lead screw as the drive component. By increasing the proportion of the transmission screw's effective stroke length relative to the total mechanism length, it reduces installation space requirements, decreases equipment size and weight, thereby lowering overall costs. The self-locking feature of the lead screw enhances operational safety and reliability. Additionally, the motor required for this system can be configured without brake pads, further reducing production costs.

With the advantages of high precision, stable transmission, self-locking and easy adaptation, the lead screw can accurately control the displacement of scanning bed and injection pump in medical equipment to ensure the accuracy of diagnosis and treatment. It can also improve patient comfort, ensure safety of use, help equipment miniaturization and cost reduction, and adapt to multiple medical scenarios.
