Swivel Ring Double Hook, Rotating Finger Ring

What the swivel ring double hook is

The swivel ring double hook is a two pronged skin hook whose finger ring turns. The ring rotates through a full circle against the shaft, so the direction of pull can be changed while the prongs stay exactly where they were placed.

That is the one thing a fixed hook cannot do. With a fixed handle, changing the angle of traction means taking the prongs out and putting them back in, and every re entry is another two holes in a skin edge that is already thin.

So this is the hook for dissection, where the direction of pull changes constantly as the plane is followed. For a hold that never changes angle, a fixed hook is simpler and there is no reason to pay for a bearing.

Key design features of this adjustable skin hook

Four features, and the ring is three of them.

• Swivel finger ring. Turns through a full circle, so an adjustable skin hook changes angle without changing grip.
• The prongs stay put. The angle moves and the tissue does not, which is the whole argument.
• Two sharp prongs. A flap is held on two points and cannot rotate off.
• Worn on a finger. Like the thumb hook, it is worn rather than gripped, so the hand does not tire.

Swivel ring double hook size

What we can state is what our own record carries, and for this pattern that is the configuration rather than a figure.

No prong width and no overall length is stated, because our record holds neither. Other catalogs list this pattern with prong widths of their own and none is repeated here. Ask and it will be measured.

Where a swivel ring nasal tip retractor is used

A swivel ring nasal tip retractor belongs wherever the plane moves and the traction has to follow it.

What the prongs hold, and what they do not

A swivelling hook is still a sharp hook, and the limits are the limits of any sharp hook.

How it compares with the rest of the family

Four of the rows below are our own. Three instruments in this category are worn on a finger or thumb, and the difference between them is what the ring does once it is on.

Materials and finish

Made from high quality medical grade stainless steel, satin finished so the operating light does not reflect off the shaft into the surgeon eye. The steel itself is made to a German specification. The swivel is the part that matters: it is finished so the ring turns under finger pressure alone, because a swivel that needs a tug is a fixed hook with extra parts.

Care and sterilization

Clean with a soft brush under running water, working the prongs, the ring and above all the swivel joint, then rinse in deionized water and dry fully before autoclaving. The joint is the one part of this instrument that can seize, and it seizes from dried protein rather than from wear, so it is worth a few extra seconds. Turn the ring through a full circle before the instrument goes back into the set: if it catches anywhere, it is not doing the job it was bought for.

Frequently asked questions

What is a double hook used for?

Holding a skin edge or a flap on two points instead of one, so it cannot rotate around a single puncture and tear. In a nasal set it is used on dermal edges, nasal tip tissue and skin flaps during rhinoplasty, cleft repair and fine facial dissection.

What does the swivel actually do?

It lets the ring turn against the shaft. In practice that means the assistant can change the direction of pull as the dissection moves without lifting the prongs out of the tissue. On a fixed hook the same change means re entering the skin, and each re entry is another hole.

When would a fixed hook be better?

When the angle never changes. A straight pull held in one direction for a whole step needs no bearing, and a simpler instrument is easier to clean and has nothing to seize. Buy the swivel for dissection, not for static retraction.

Is this the same as a double hook retractor?

A double hook retractor is the general term for any two pronged hook, and there are many. This one is the version with a turning ring. If the catalog you are reading does not mention a swivel, it is a fixed hook under the same general name.

How many prongs, and how sharp?

Two, and sharp. The prongs are cut to enter a dermal edge cleanly rather than to be forced through it. That makes the instrument unsuitable for mucosa, which needs a blunt ball ended pattern instead.
