Allis Tissue Forceps, Interlocking Teeth, Ratchet Lock

What the Allis tissue forceps is

The allis tissue forceps is a ring handled grasping instrument that holds dense, slippery or heavy soft tissue and locks there on a ratchet. It is listed just as often as an allis clamp, and catalogues also carry it as allis forceps, allis tissue clamp and allis tissue holding forceps. The jaw is curved and fenestrated, and it ends in teeth that interlock when the handles close.

Those teeth are the whole instrument, and they decide where it belongs. They anchor tissue at a point instead of pinching it flat, which is what stops fascia sliding out of the jaw. They also mark what they hold, so this is an instrument for tough structures and for tissue that is being removed, not for anything that has to be left intact.

Key design features of the Allis tissue forceps

Four things together make the grip, and the instrument stops working properly if any one of them is worn.

• Interlocking teeth. The rows at the jaw tip pass between each other, so tissue is trapped rather than squeezed.
• Fenestrated jaw. The open center lets you see what you have hold of before the ratchet goes on.
• Curved jaw. The curve follows a tissue edge instead of standing across it.
• Ratchet lock. Set the hold at the handle and let go, then release it one handed.
• Box joint. The two halves pass through each other, so the teeth stay meshed after years of use.

Allis tissue forceps sizes and build options

The size chart is the variation list, so what is shown is what ships. Choose the length on the Select Size field.

Imperial figures are given because most United States buyers order in inches. Tooth counts differ between makers on this pattern, and we do not quote one here, because the number on your tray should come from the instrument in your hand rather than from a catalogue. Ask us before you order if a specific count matters to your set.

Allis tissue forceps uses by specialty

What these uses share is tissue that a smooth jaw lets go of. The specialty is in the first column and the procedure words are in the second, because those are the phrases surgeons actually search.

What the jaws hold

This is a grasping instrument and not a needle holder, so there is no suture gauge to quote. What matters is which structures the toothed jaw is for, and the honest answer includes the one it is not for.

How the Allis tissue forceps compares with other patterns

One comparison comes up more than all the others put together, and it is worth answering plainly: the Babcock. We do not make a Babcock, and the row below says so rather than pretending otherwise.

Allis tissue forceps materials and finish

The allis tissue forceps is made from high quality medical grade stainless steel, hardened so the teeth keep their shape and stay meshed. A tooth that wears round stops anchoring, and on a grasping instrument that is the first thing you notice. The finish is satin rather than mirror, which cuts glare under operating lights. The steel itself is made to a German specification. The finished instrument carries the CE mark.

There is no carbide insert and no coating on this pattern. The hold comes from the tooth geometry and from the hardness of the steel behind it, and an insert at the tip would blunt the very thing that anchors the tissue.

Allis tissue forceps care and sterilization

Rinse under cold running water immediately after use, and give the teeth particular attention, because tissue lodges where they mesh and dries there. Use a soft brush, never wire. Open the jaws fully for ultrasonic cleaning and for autoclaving, so the box joint drains and steam reaches the ratchet. Dry completely, then store with the ratchet released so the spring is not held under load.

Frequently asked questions

What are Allis tissue forceps used for?

They hold dense, slippery or heavy soft tissue that a smooth jaw would release, and lock there on a ratchet. In practice that means fascia and muscle sheath at opening and closure, tendon in orthopedic exposure, and any tissue that is being excised. They are not used on structures that have to be preserved.

What are the key differences between Allis and Kocher forceps?

The tooth arrangement. An Allis carries rows of fine teeth across the width of the jaw tip, so it holds a broad edge of tissue along its length. A Kocher carries a single tooth meeting two at the very tip, so it anchors at one point and is built to clamp as well as to hold. Reach for the Allis on a tissue margin and the Kocher on fascia you also need to close.

What are the key differences between Babcock and Allis forceps?

The Babcock has a smooth, hollowed jaw and no teeth, so it holds delicate tubular structures such as bowel, ureter or fallopian tube without marking them. The Allis has interlocking teeth and a much stronger grip, which is why it goes on fascia and on tissue being removed. We make the Allis and we do not make the Babcock.

What are the uses of Allis forceps?

Grasping, retracting and steadying tough soft tissue while something else is done to it. The common ones are holding the abdominal wall during closure, steadying the vaginal wall at episiotomy repair, taking bowel margins that are being removed, and holding a flap edge in reconstructive work.

Who invented Allis tissue forceps?

The pattern carries the name of Oscar Allis, an American surgeon. Catalogues usually date it to the 1880s, though we do not claim a specific year on this page because we have not verified one.

Surgeons who work with the allis tissue forceps usually compare it against the adson hemostatic forceps, the insulated adson hemostatic forceps and the kocher delicate artery forceps. The whole family sits in hemostats and grasping forceps, and this pattern is also listed under breast surgery instruments.
