Knapp Retractor

Description

Knapp Retractor

The Knapp retractor is a small rake with blunt prongs. It measures 13 cm and holds back skin and soft tissue gently. Surgeons often use it in lacrimal sac and lid work, where the field is small.

Blunt Prongs, Gentle Hold

Blunt tips spread the load across the tissue. So they are less likely to tear or puncture than sharp prongs. That matters near vessels and thin lid skin. It also makes the Knapp retractor a forgiving choice for teams in training.

Typical Knapp Procedures

In general, Knapp-style rakes help expose the lacrimal sac during dacryocystorhinostomy. They also suit other small lid and orbital incisions. However, they are not meant for heavy retraction. For deep or wide wounds, a larger self-retaining retractor makes more sense.

A Handy 13 cm Length

At 13 cm, the retractor gives the assistant a clear grip. Meanwhile, the hand stays out of the surgeon’s way.

• 13 cm overall length
• Blunt prongs to protect tissue
• Light rake for small fields
• Reusable after sterilization

Using It With a Partner

An assistant usually holds the rake. Then the surgeon adjusts its angle as the wound deepens. Because the prongs are blunt, small shifts cause little harm.

Keeping the Prongs Even

Check that all prongs line up before each case. A bent prong catches tissue. Also clean between the prongs using a small brush, since debris collects there. Finally, dry the rake fully before storage to avoid water spots.

Knapp retractors leave us non-sterile and handle many cases with proper cleaning and sterilization. The stainless steel used here meets ASTM F899, and finished rakes pass our checks in the United States. We back every Knapp with three years against manufacturing defects. If you want a sharp or blunt choice, compare the Graefe rake retractor. More tools sit in our eye surgery category, and the ordering help answers common questions.
