Frequently Asked Questions

What is a Cottle Septum Knife used for?

The Cottle septum knife is primarily used for making precise, controlled incisions in the nasal mucosa and mucoperichondrium during rhinoplasty and septoplasty operations. Its sharp 4mm straight blade allows surgeons to initiate septal exposure cleanly without tearing surrounding delicate tissues.

What is the difference between a Cottle Septum Knife and a Freer Elevator?

A Cottle septum knife features a sharp, narrow blade designed specifically for slicing through skin and mucosal layers during the initial incision phase. In contrast, a Freer elevator features blunt or semi-blunt curved ends used for blunt dissecting and lifting the mucoperichondrial flap away from the cartilage after the incision is made.

Is the Cottle Septum Knife autoclavable?

Yes, this instrument is fully autoclavable and reusable. Constructed from premium German stainless steel, it is engineered to withstand standard steam autoclave sterilization cycles (up to 134°C / 273°F) without rusting or degrading blade sharpness.

Are custom branding and OEM options available for wholesale orders?

Yes, Healermed Instruments offers custom laser branding, OEM packaging, and private labeling options for wholesale clients, distributors, and surgical brands.
