What are tenotomy scissors?

Tenotomy scissors are a type of surgical scissors used to cut small tissues and maneuver in delicate areas. The name itself refers to the surgical tenotomy, which involves partially incising or cutting the tendons. These scissors feature extremely small blades with very large handles, which provide a stable grip while maintaining precision and allowing access to small areas. They may also be known as scissors stevens either Stevens tenotomy scissors .

Surgeons may use tenotomy scissors for operations in small-scale or difficult areas, such as the eyelids, lips, and brain. Urological, neurological, and ophthalmic procedures especially benefit from the size, shape, and delicacy afforded by narrow blades, although this type of scissor is a staple in almost every surgical setting. They are commonly used for precision surgical dissection and tissue transplants in difficult areas. Some of the sharpest scissors are also capable of cutting small bone and cartilage in places like the nasal cavities.

The average pair of Stevens scissors has blades exactly 4.25 inches (10.8 cm) long. The blades are curved or straight. Tenotomy scissors with longer blades average 4.5 inches (11.4 cm) in length, although larger and smaller variations are available. The most common material for tenotomy scissors and other surgical scissors is stainless steel, although some may be made of titanium or another durable metal that can be easily sterilized. Handles are typically coated with an oxidized material for easy identification and recognition in the surgical environment.

Straight and curved blades are available in blunt or sharp point models. Surgeons may prefer curved scissors because of the increased visibility and maneuverability the design offers. Sharp-tipped scissors are useful for careful cutting, while blunt-tipped scissors can be used to dissect mucous membranes and other soft tissue. Other models may include a lighter design, a different style of handle, or specialized serrated blades for a sharper edge.

Tenotomy scissors are also widely used in veterinary practices, especially on small domestic animals. Many domesticated animals have smaller tissues and membranes than humans. This makes Stevens scissors useful for veterinary surgeries where smaller scissors are needed in general, rather than just for more delicate areas.

This also makes them ideal for animal dissection in a laboratory setting, or in a biology classroom. Many students use Stevens scissors or iris scissors in dissection projects, just as scientists use them to dissect and analyze animal tissue. Tenotomy scissors can also be useful for cutting delicate tissue during autopsy procedures.
