Surgical needles

The atraumatic needles and eye needles used in surgery have to meet a wide variety of requirements. We therefore offer a wide range of needles, suitable for many different indications. We use only stainless steel needles with excellent material properties that allow the surgeon to work easily and safely.

SERAG-WIESSNER eye and spring eye needles are characterised by their optimal bending resistance, excellent ductility and outstanding penetration capacity. These features allow the surgeon to work safely and easily.

Atraumatic needles are firmly attached to the suture ("swaged"), which minimises tissue trauma. We provide a wide range of atraumatic needles for these needle-suture combinations.

To the Needle showroom


Our needles are identified by means of a combination of letters and numbers, as recommended by the Technical Committee of the Registered Association of Surgical Suture Material Manufacturers. The first letter denotes the needle shape, the second letter denotes the needle type. If a third or fourth letter follows, this refers to particular features of the needle. The number after the letters denotes the length of the needle in mm when straightened.

Explanation of the surgical needle code

Needle shape

D = 3/8 circle
F = 5/8 circle
G = straight needle
H = 1/2 circle
K = semi-curved
L = spoon needle
V = 1/4 circle

Needle type

R = round-bodied needle
S = reverse-cutting needle

Special features:

A = asymptotic
K = taper cutting
L = lancet point
M = micro point
N = blunt, round-bodied needle
S = slim point
SP = spatula needle
T = trocar point
X = extra strong
F = fine needle

Steel quality used for needles

Nowadays, it can be assumed that manufacturers, at least European ones, generally use stainless steel needles, i.e. made from non-corroding steel, for their surgical suture materials. We use 300 series steel almost exclusively in our manufacturing process, in order to guarantee the excellent characteristics of our needles.

The following classes of stainless steel are usually used in the manufacture of surgical needles:

420 series:
standard steel quality, martensitic, minimal ductility, lowest bending force
455 series:
improved 400 series quality, martensitic, better ductility, higher bending force
300 series:
best steel quality, austenitic, the best ductility, the best bending force. This quality is often only offered for cardiovascular surgery.
