Kerrison Punch Forceps

Description

Kerrison Punch Forceps

The Kerrison punch forceps removes bone in thin, controlled bites. Its footplate slips under the edge of the bone, and the cutting edge punches upward.

How a Kerrison punch works

The flat footplate sits beneath the bone, protecting the tissue below. Then the cutting edge slides forward and punches out a small piece. As a result, the surgeon removes bone with little risk to the dura.

Four bite sizes

This version has a 90 mm shaft. In addition, you can choose an upward bite of 3, 4, 5 or 6 mm. Smaller bites suit tight spaces near nerves.

Who uses Kerrison punch forceps

Spine surgeons use them for laminectomy and foraminotomy. Also, neurosurgeons use them in decompressions. Moreover, they suit some cranial base work as well.

Safe technique

Place the footplate carefully under the bone edge. Then check that no soft tissue sits in the bite. Withdraw and clear the fragment after each punch.

A short shaft

A 90 mm shaft suits cervical and shallow work, where long shafts feel clumsy. Consequently, this length gives fine control. Deeper levels may need a longer shaft.

Kerrison punch forceps options

• 90 mm shaft
• Upward bite: 3, 4, 5 or 6 mm
• Footplate design
• Supplied non-sterile

Care of a sliding punch

Flush the sliding track and the bite thoroughly. Lubricate moving parts once dry. Check that the cutting edge closes cleanly against the footplate.
