What is the difference between a Lamina Punch and a disc rongeur?

They are two distinct architectures in the MEDLANE catalogue. The Lamina Punch — designated “Lamina Punch Rongeur” — combines a pistol grip, a shaft and a footplate beneath a cutting bite (for example 42374, 180 × 5 mm, 90° high). The disc rongeur — designated “Rongeur Disque” — combines a ring handle with a cup jaw whose dimensions are written into the designation (for example 42108, Spurling 180 straight 4 × 10).

What do the “high” and “low” markings mean?

They are written into the catalogue designation next to the angle. At identical length, width and angle, MEDLANE references for example 42374 (180 × 5 mm 90° HG) and 42377 (180 × 5 mm 90° LOW): comparing the two plates isolates exactly that marking.

How do you read the designation of a MEDLANE Lamina Punch?

It carries the working length then the bite width, the angle, the high or low marking and the dismountable option — for example 42357 (200 × 3 mm, 90° HG, dismountable).

What is a fenestrated disc rongeur?

It is a MEDLANE catalogue designation: the word “Fenêtré” appears in the reference name, as on 41827 (Caspar fenestrated 140 straight 2 × 12) and 41839 (Caspar fenestrated 180 straight 6 × 16).

Kerrison rongeurs & disc rongeurs: understanding spinal resection instruments

Two instrument families meet on a spinal surgery table, and they are not interchangeable. The MEDLANE catalogue designates them differently: “Lamina Punch Rongeur” and “Rongeur Kerrison” on one side, “Rongeur Disque” on the other.

The difference shows first in the silhouette: a pistol grip with a footplate slid beneath the bite, or a ring handle extended by a cup jaw. This guide separates the two architectures, then reads what the designation writes: length, width, angle, high or low marking, dismountable or fenestrated option.

No clinical usage guidance here: only what an eye can verify on the instrument and on its reference.

Lamina Punch

The Lamina Punch family

Four references from the MEDLANE Lamina Punch series: the pistol grip and the footplate are shared, only the dimensions and the angle change.

HIGH / LOW · 180 mm · 5 mm · 90°

Identical length, width and angle: this is the only comparison that truly isolates the high or low marking of the catalogue designation.

Disc rongeurs

The other architecture

Four disc rongeur families from the MEDLANE catalogue, all in the straight version: ring handle, shaft, and a cup jaw whose dimensions are written into the designation.

L'ŒIL MEDLANE · 01

Five things to look at before naming the instrument.

The handle: pistol grip on the Lamina Punch and Kerrison architectures, closed finger rings on the disc rongeurs.
The working end: a bite closing onto a footplate, or a cup jaw closing onto its counterpart.
The width written into the designation: bite width in mm on a Lamina Punch, cup dimensions in mm on a disc rongeur.
The angle and the high or low marking, on the references whose designation carries them.
The options written into the designation — dismountable, fenestrated — and the exact reference, which alone identifies the configuration.

Every characteristic quoted here is the one carried by the catalogue designation of the reference shown. No designation is rewritten: the MEDLANE nomenclature is reproduced as it stands.
