Iris Scissors Razor Edge, Micro Dissection, 9 cm to 11.5 cm, Standard or Tungsten Carbide

What iris scissors razor edge are

Iris scissors razor edge are short surgical scissors, 9 cm to 11.5 cm long, whose cutting edge is ground to a finer bevel than a standard blade and then honed. The surgeon holds them by two finger rings. The finer grind parts thin tissue rather than pressing it ahead of the blade, which is why razor edge iris scissors are reached for on conjunctiva, vessel wall and lid skin, where a dragged edge is visible afterwards.

Applications

Eye surgeons order this pattern as fine ophthalmic scissors. These are the procedures Adas Instruments supplies it for.

Size chart

Standard razor edge and tungsten carbide razor edge

Both builds carry the same razor grind. The standard build is plain medical grade stainless steel and suits lighter use. The tungsten carbide build adds a carbide insert on the cutting edge and holds the grind through far more reprocessing cycles, which is what a set autoclaved every day needs. Adas Instruments makes both in all three lengths.

Technical specification

Made in Sialkot by Adas Instruments

Adas Instruments grinds and finishes these micro dissection scissors in Sialkot, Pakistan. Every pair is passivated, boil tested, ultrasonically cleaned and individually packed, and ships non sterile and fully autoclavable under a 3 year warranty with a lifetime cover against manufacturing defects, to ISO 13485 and CE mark.

Care and reprocessing

A razor grind needs more care than a standard bevel because there is less metal behind the edge. Wash these fine dissecting scissors in an ultrasonic bath and get the fluid right into the points, since dried blood at the tip is what blunts them first. Lubricate the screw joint after every cycle. Autoclave in the open position. Never cut wire, suture packets or drape with a razor edge, because that rolls the grind and no sharpening fully brings it back.

Frequently asked questions

What does razor edge mean on surgical scissors?

A razor edge is a blade ground to a much finer bevel than a standard surgical blade, then honed. It parts tissue instead of pressing it, so the cut edge stays clean and the tissue is not dragged along the blade. Adas Instruments grinds the razor edge on iris scissors razor edge in Sialkot, Pakistan.

What is the difference between razor edge and standard iris scissors?

A standard iris scissor has a conventional bevel and cuts well on skin and suture. Iris scissors razor edge carry a finer honed grind that suits thin, mobile tissue that a standard bevel tends to push ahead of the blade. Surgeons keep the standard pattern for general work and reach for the razor edge for the fine pass.

What is the difference between the standard razor edge and the tungsten carbide razor edge?

Both carry the same razor grind. The tungsten carbide build adds a carbide insert on the cutting edge, which holds that grind through far more reprocessing cycles than plain steel. Choose the standard build for lighter use and the tungsten carbide build for a set that is autoclaved every day.

What size iris scissors razor edge should I choose?

Adas Instruments makes them at 9 cm, 10.5 cm and 11.5 cm. 9 cm suits eyelid and micro work, 10.5 cm suits general fine dissection, and 11.5 cm suits plastic surgery and rhinoplasty where the hand sits further from the tissue.

Can iris scissors razor edge be autoclaved?

Yes. They are supplied non sterile and are fully autoclavable. Sterilise them in the open position so steam reaches the whole joint, and keep them off wire, suture packets and drape, because a razor grind rolls faster than a standard bevel.
