Our surgical needles have been adopted by 161 companies in 54 countries. In Europe and the U.S., where particularly high quality is required, our needles have cleared strict quality standards such as MDR, and we boast a high in-house share and adoption record.

We provide various types of needles custom-made to meet the needs of our customers.

Sharpness

Cross-lapped Edge

MANI’s fine-processing technology has created this unique cross-lapped edge which provides such exquisite sharpness and stable quality. (Crossword-lapped edge: Polishing direction is vertical to the edge) *This technology is employed in some of our needle types.

Silicone

MANI’s silicone-coating technology allows it to produce needles that present excellent initial penetration performance as well as high durability after series of penetrations. As the lineup also includes coated needles that do not have silicone applied to the swage, they are able to meet the needs of both manufactures and doctors.

Safety

"MANI's original hard-fiber stainless steel"

MANI Hard-Fiber Stainless steel provides reliable strength from the tip to the end. This original material allows MANI to produce needles with high ductility, bending strength, and corrosion resistance.

Swage

1972 was the year when MANI applied laser drill technology to manufacture suture needles for the first time. MANI’s swage design incorporates several key technologies to prevent unnecessary injuries during tissue penetration.

Special treatment

The sage is specially processed to achieve optimal thread retention, leading to stable pull-out strength.

Laser drill

Its sophisticated laser drill technology allows MANI to create a drilled end on the micro needles, further improving non-invasiveness.

Outside chamfering

The outside edge is cut off to avoid tissue damage from a corner.

Inside chamfering

The inside edge is also cut off to minimize damage to delicate thread.*Not all MANI needles are made involving outside and inside chamfering. Please send us an inquiry for further information.

Black Needle

MANI black needles come with a non-reflective surface treatment which allows for precise tissue penetration and better visibility during surgical procedures where blood is present in the operating field. This black surface treatment is available for a variety of needle types.
