What is a medical spring?

Medical springs" are high-precision springs (precision springs/precision springs) used in medical equipment and medical supplies.

Compared to general springs, durability and corrosion resistance are often required, and special materials and processing techniques are needed to meet the operating environment.

Examples of items in which medical springs are used

use	Description of use	Spring Details
catheter	A flexible tube inserted into a blood vessel. Medical springs are used at the tip of catheters to support flexibility and stretch within narrow blood vessels.	Very fine wire diameter (about 0.02 mm to 0.1 mm), requiring high-precision processing and durability.
endoscope	A medical device used to observe the digestive tract and organs in the body. A camera is mounted on the tip and inserted into the body through a flexible tube.	To improve operability, ultra-thin compression springs or torsion springs are used in the moving parts of the insert. They must be highly durable and must be processed to achieve smooth movement.

Since these products are in direct contact with the human body, they require precision processing technology and high quality standards.

How to choose a supplier for medical spring processing

When selecting a supplier to process medical springs, check the following points

Do you have experience in processing medical springs and precision springs?

Medical devices require very strict quality standards, so it is important to choose a supplier with a proven track record in the manufacture of medical springs and precision springs.

Check past delivery records and the materials and shapes that can be handled.

Is the processing suitable for the application?

There are many different types of springs.

Types of springs

• Coil springs: compression coil springs, tension coil springs, torsion coil springs
• Plate springs: Overlapping plate springs, thin plate springs
• Forming (wirework spring)
• spiral spring
• bar spring (e.g. spring trumpet spring)
• dish spring
• torsion spring
• fastener spring
• leaf spring

Most springs used in medical applications are made of metal.

These are processed (formed) for medical use, and there are many types of processing methods such as winding, bending, cutting, pressing, and surface treatment.

Check if the official website lists the types of processing that can be handled and past results, and check if the manufacturing and processing can be done to meet your purpose and application.

Is the quality assurance system sufficient?

When choosing a supplier for medical springs, check whether they have obtained certifications such as ISO13485 (quality management standard for medical devices) or ISO9001 (quality management system).

ISO 13485 assures quality control in the design and manufacture of medical devices, and ISO 9001 is the standard for overall quality management.

Contractors who have obtained these certifications can provide products of stable quality under strict quality control, so you can feel confident in asking them for their services.
