Cone Cranial Punch

Description

Cone Cranial Punch

The Cone cranial punch bites skull bone to enlarge an opening. Neurosurgeons take it up after drilling, nibbling outward from a burr hole one bite at a time.

Enlarging holes in the skull

A burr hole is often too small for the planned work. So, the surgeon uses a punch to bite bone from its edge. Because each bite is small, the surgeon controls the final shape closely.

Length

We list the punch at 23 cm. Our catalogue source gives about 22.5 cm, so the actual piece may measure slightly less. If exact length matters, ask and we can put a ruler on a stock piece.

In cranial surgery

First, a drill creates the burr hole. Next, the punch slips under the bone edge and bites outward. Then the surgeon repeats this until the opening reaches the needed size. Meanwhile, a dura dissector can keep the dura away from the bone edge.

Planning your cranial set

A cranial punch works alongside drills, elevators and rongeurs. For instance, some teams use a rongeur for broader bone removal and the punch for finer edges. Also keep a dura dissector close by to protect the membrane.

Caring for your Cone cranial punch

Flush bone chips out of the jaws straight after surgery. Next, brush the joint and working end thoroughly. Then dry the punch and check that it closes cleanly before sterilization.

Buying the Cone punch

Our three-year warranty extends to this punch for any lapse in workmanship. Before it leaves Atlanta, one of us checks the bite action by hand. General purchasing answers live on our FAQ help section. As for alloy, ASTM F899 spells out which steels belong in instruments like this. To protect the dura beside the punch, add a Frazier dura dissector. There is more in the neurosurgery range on our site.

Intended for professional use. Our care page answers questions about product images and about nickel in the steel. For dispatch times, visit our shipping and delivery information.
