In addition
to the standard and post mortem range Barber offer a
range of special needles such as drilled end, channel
and micro needles.
Eyed needles can be offered
in regular or french/open Eye and in conventional cutting
as well as reverse cutting.
Drilled end needle are
precision drilled for maximum holding strength and they
have an ultra smooth finish |

Conventional cutting needles
have the cutting edge on the inside of the needle curvature
and hence directed towards the wound. Suture tension
is therefore at the top of the triangular part of the
needle and tear resistance is weak. Reverse cutting
needles have the cutting edge on the outside and the
flat surface toward the wound and this may offer better
resistance against tissue wear. Reverse cutting needles
however, do require more force to penetrate the tissue.
Round bodied needles taper gradually
to a point whereas triangular bodies have cutting edges
along three sides.
Heavier gauge DIN standard needles can
also be supplied.
