Stevens Tenotomy Scissor 11 cm / 4-1/2" Straight

The Stevens Tenotomy Scissor, 11 cm / 4-1/2" straight, is often confused with an iris scissor but differs in one important respect. Both are fine instruments with short blades, yet the iris tips are sharply pointed while the Stevens tips are blunt and rounded. That difference changes the technique available. A Stevens scissor can be introduced closed into a tissue plane and opened to spread it, separating structures without cutting, which is the safest way to work around a vessel or nerve.

An iris scissor cannot be used this way without risk of puncture. The Stevens still cuts cleanly when division is required. It is used in ophthalmic surgery, fine soft tissue dissection and procedures around delicate structures where blunt separation is preferred.

• Fine short blades with blunt rounded tips, unlike a pointed iris pattern
• May be introduced closed and opened to spread a tissue plane
• Separates structures without cutting, the safest approach near vessels
• Retains clean cutting ability where division is required
• Straight configuration for a direct line of approach
• Used in ophthalmic surgery and fine soft tissue dissection

How does a Stevens differ from an iris scissor?

Both are fine, but Stevens tips are blunt and rounded, which allows safe blunt spreading that a pointed iris tip cannot.

What is blunt spreading?

The closed tips are placed in a tissue plane and opened, separating structures along their natural divisions without cutting.
