Meniscus Repair Curved Needle: Precision for Minimally Invasive Surgery

In minimally invasive knee procedures, meniscus repair requires surgical instruments with precise dimensions, curvature, and tip geometry.

Recently, a customer approached SHOMEA with a specific requirement for a curved needle designed for a meniscus repair device.

The customer had already finalized the overall instrument design, but standard surgical needles could not meet the required curvature and dimensions. A customized solution was needed.

Why Use a Curved Needle for Meniscus Repair?

Compared with a straight needle, a curved needle can provide a different approach angle and help access areas that may be difficult to reach with a straight design.

For minimally invasive surgical instruments, the needle’s curvature, radius, length, and tip geometry need to match the overall instrument design and intended application.

A curved needle is not simply a straight needle that has been bent. Its dimensions and forming process need to be carefully controlled.

What Did the Customer Need?

For this project, the customer required:

• Specific needle diameter
• Customized needle length
• Precise bending angle
• Consistent bending radius
• Customized needle tip geometry
• Smooth surface finish
• Stable dimensional consistency for production

Among these requirements, controlling the bending process was particularly important.

Even a small variation in the bending angle or position could affect subsequent assembly and the overall performance of the instrument.

How SHOMEA Develops the Solution

After receiving the customer's drawing or sample, SHOMEA evaluates the dimensions, material, bending structure, and tolerance requirements to develop a suitable manufacturing process.

Depending on the design, production may involve precision cutting, needle tip forming, bending, surface finishing, and dimensional inspection.

For custom curved needles, we focus not only on the final dimensions but also on the coordination between different manufacturing processes to achieve stable and consistent production.
