Lange Wilde Polypus Nasal Snare | Bayonet Shaft, Fig 0 to Fig 4

What a Lange Wilde polypus nasal snare is

This is the instrument people mean when they type nasal snare with nothing else attached. A wire loop, a long cannula, a handle that slides. And the reason to reach for it rather than a cutting forceps is one sentence long: the loop crushes the stalk as it tightens, and crushing a stalk closes the vessels in it, which is why a snare bleeds less than a blade through the same tissue.

What makes it a Lange Wilde rather than a Krause is the shaft. It is a full bayonet, stepped sideways twice so the handle finishes well off the axis of the cannula: the bend puts the hand below the line of sight, so the surgeon looks down the instrument at the tissue instead of past their own knuckles. Google’s own answer for this pattern says the same thing in its own words, that the offset keeps the hand out of the line of sight into the middle and superior meatus, and that is exactly where this snare earns its length.

The loop closes on a slide. Draw the rings back and the wire retracts into the mouth of the cannula; how fast it goes is your decision. Some makers fit a ratchet or a calibrated trigger instead. We do not: a stalk being crushed tells you what it is doing through your fingers, and a ratchet trades that for a number you did not need.

Our record carries Fig 0 to Fig 4 for the loop and no dimension at all. The rival listings Google names run 16 cm and 24 cm, at anything from the same price as ours to six times it. Those are their instruments and their lengths. Ask us for a working length and you will get ours.

One thing worth saying plainly: a nasal polyp snare only works on a polyp with a neck. If the growth is sessile there is nothing for the loop to sit behind, and the instrument for it is a fenestrated forceps.

Key design features

The bayonet shaft, which is the whole difference

Two sideways steps between the handle and the cannula. Your knuckles end up below and outside the nostril axis, so the light, the view and the instrument share one corridor instead of fighting for it. That matters more here than on most instruments, because placing a loop is done by eye and by feel at once.

A sliding loop, not a ratchet

Pull the rings and the wire draws into the cannula. Nothing clicks and nothing holds a position for you. That is deliberate: the crush is the procedure, and the only sensor you have for it is the resistance coming up the slide into your fingers.

Fig 0 to Fig 4 loops, replaceable

Five loop sizes on our own record. The wire is a consumable, sold in packs of 12 in the same range, and a loop drawn through a fibrous stalk is replaced rather than straightened. One handle sees out several hundred.

Length that reaches the back of the nose

The cannula is long because the polyps worth snaring are often not at the front. An antrochoanal polyp comes through the choana, and its stalk sits further back than a short instrument reaches.

Which Fig size to order

Five loop sizes from our own record. Every length and gauge on rival pages belongs to rival instruments.

Where it is used

An ENT polypectomy snare, and the list of what that covers is short and honest.

What it takes, and what it must not do

Every row follows from one fact: a loop needs a neck.

How it compares with the other polypus instruments

The question we get most often is the first two rows, so it is answered in the FAQ as well.

Materials and finish

Every Lange Wilde polypus nasal snare we make is cut from high quality medical grade stainless steel. The steel itself is made to a German specification. We do not publish a grade number. A certificate says nothing about whether a bayonet shaft still runs true after it has been dropped, because a snare with a shaft that is a degree out of line closes its loop somewhere other than where you aimed it. The answer to that is in the making rather than in the alloy.

The two bends are the difficult part of this pattern. They are formed and then stress relieved, because a cold bend that is never relieved is where a shaft eventually cracks, and it cracks at the bend rather than anywhere you are watching.

The mouth of the cannula is finished square and polished, since every wire drawn in runs against that one lip of steel. The slide is polished rather than ground, because a ground finish feels gritty on the one movement that is the operation.

Caring for it

Take the wire out before cleaning, every time. A snare autoclaved with a used loop in it bakes tissue into the one channel you cannot brush.

Flush the cannula, brush the handle, dry it with the slide fully back. Autoclave with the tray. Work the slide when it comes out: full travel, no catch. A sticky slide is debris rather than wear. Check the bends against a flat surface once a year.

Ordering and wholesale

Every Lange Wilde polypus nasal snare is made by Adas Instruments in our own workshop and sold direct, which is why the price sits where it does against the catalog houses. Order one for a single tray, or in quantity for a hospital list or a distributor line. We do OEM work under your own brand and your own item numbers. Send us a sample and we will hold a run to your pattern rather than ours. Stock items ship from our own workshop. Backorder items take 10 to 12 working days to make. Every instrument carries a three year replacement warranty against manufacturing defects. Production is controlled under an ISO 13485 quality management system.

Frequently asked questions

How does the Lange Wilde snare compare to the Krause snare?

The mechanism is the same on both: a wire loop that tightens and crushes through the stalk. The difference is the shaft and the handle. The Lange Wilde is the full bayonet, stepped twice so the hand finishes well off the axis, and it is the one to pick when the polyp is in the middle meatus or back at the choana and the view is the thing you cannot afford to lose. The Krause has the three ring handle with a rotating thumb ring, so you can turn the plane of the loop without turning your wrist, and it is the easier instrument on an anterior polyp you can see properly. Both take the same Fig 0 to Fig 4 wires. If you are buying one, buy on where the polyps you see actually sit.

What is a nasal snare used for?

Taking off a growth that has a stalk. The loop goes round the neck, the slide pulls it tight, and the stalk is crushed through: nasal polypectomy, antrochoanal polyps, polyps in the middle meatus, and the occasional aural polyp.

Why does a snare bleed less than a cutting forceps?

Because the loop closes the vessels in the stalk while it is going through it. Crushing and cutting are different injuries, and the crushed one seals as it is made. That advantage disappears if there is no stalk, which is why a sessile polyp is not a snare job.

Can the wire loop be replaced?

Yes, and it is designed to be. We sell nasal polypus snare wire in packs of 12 across the same Fig 0 to Fig 4 range, and the handle outlasts several hundred of them. A loop that has been drawn through a fibrous stalk is thrown away, not straightened.

Does it have a ratchet?

No. It closes on a slide, and we keep it that way on purpose. The resistance coming back up the slide is the only feedback you get on how the stalk is giving, and a ratchet trades that for a position you did not ask for.

Related products and categories

The other snare in this family is the Krause nasal polypus snare, the three ring pattern. The loops are the nasal polypus snare wire, pack of 12, and when the polyp has no stalk the instrument you want is the Hartmann nasal polypus forceps.

The rest of this family sits under nasal speculum and polypus instruments, and the cutting and crushing forceps for the same operation are under nasal cutting, crusher and septum forceps.
