Mayo scissors are a type of surgical scissor , often used in the cutting of fascia. Mayo scissors were developed by Mayo Clinic surgeons. Mayo scissors may be made from stainless steel or titanium , with stainless steel ones being markedly cheaper than titanium ones. Like most other modern-day surgical instruments, a vast majority of Mayo scissors are made from stainless steel and are disposable due to convenience, as such scissors do not need to be sterilized and reprocessed. Straight- and curved-blade varieties of Mayo scissors exist, each of which is particularly suited to specific surgical, including veterinary and podiatric surgery applications.

Like needle drivers, scissors are held in the thumb and ring finger. This allows for the tip of the scissors to remain stable while the arm supinates and pronates. A common error is to hold the scissors in the thumb and either the middle or index finger. This swings the tip of the scissors to the side and reduces control. The index finger is used to support the scissor, and can be placed on the screw head for maximum control. Mayo scissors are heavy scissors that can be straight or curved. They are most frequently slightly curved. A common mistake is to use Metzenbaums to cut suture, which dulls the scissors and renders then less useful for dissection. Iris scissors are even finer than Metzenbaums and are used for cutting fine structures. They are short, straight, and sharp.

An instrument that permits excision by a crushing action is an ecraseur. A common error is for the suture scissors to obscure the knot, which risks cutting the suture too short.

Dissecting scissors are used to separate and differentiate tissues because they are more precise than operating scissors. Tools Tools. Common Errors: A common error is for the suture scissors to obscure the knot, which risks cutting the suture too short. Uses: Used for general cutting of sutures, gauze, and other materials; sharp blades used to cut tougher tissue and frequently used for dissection; blunt blades used for cutting materials such as tubing or gauze. Utility scissors used to cut non-biological materials such as when applying bandages removing bandages bandage scissors Suture cutting Tissue cutting and dissection Suture removal Utility scissors are also used during surgery to cut paper and other materials such as suture material that may dull the blade of a sharper instrument. Excision of tissues refers to the removal of tissues by surgical cuts. Other Names: Dissecting scissors, suture scissors, heavy tissue scissors, Mayo scissors. Utility scissors used to cut non-biological materials such as.

Scissors might seem like a fairly basic cutting tool, but many different varieties can assist in a whole host of tasks around the home, garden, and for use in hobbies or different professions.
