Study Notes
Scalpels
- Scalpels are used for precise tissue division with minimal damage to surrounding structures.
- Sharp cuts result in less trauma and faster healing in certain tissues, such as skin.
- Sharp cuts may also lead to more bleeding in some tissues, for example, the liver.
Scalpel Handles
- Scalpel handles are available in two common sizes:
- #3, often referred to as a "small animal" handle
- #4, often referred to as a "large animal" handle
- Disposable handles are also available.
- Handles often have units of measurement for reference.
- The handle size determines which size scalpel blade will fit.
Scalpel Blades
- Scalpel blades are numbered, indicating their size and shape.
- #3 Small Animal Handles fit blades ranging from sizes #10 to #15.
- #4 Large Animal Handles fit blades from sizes #15 to #22.
- Popular blades in veterinary medicine include #10, #15, #20, and #22.
- When applying a blade to the handle, grip the blade near the middle with needle drivers, ensuring the sharp edge is facing away from you.
- To remove the blade, use forceps or needle holders to grasp near the base, keeping the cutting edge away from yourself and others.
Scissors
- Scissors are used for cutting tissue, dissecting, and cutting suture material.
- Maintaining sharpness is crucial to prevent tearing rather than cutting.
- Scissors are classified by their name or purpose:
- Operating Scissors
- Mayo Scissors
- Metzenbaum Scissors
- Suture Scissors
- Bandage Scissors
- Iris Scissors
Operating Scissors
- Designed to cut inanimate objects like gauze or suture.
- Classified by blade type, either straight or curved, and blade sharpness (Blut/Blunt, Sharp/Sharp, or Sharp/Blunt).
Mayo Scissors
- Used for cutting large tissue masses, cartilage, or other non-delicate tissue.
- Available in straight or curved versions.
- They are blunt-blunt with thick blades, approximately one-third the length of the instrument.
Metzenbaum Scissors
- Designed for delicate surgical dissection.
- Have blades that are thin and approximately one-quarter the length of the instrument.
- Their long, thin shaft makes them more delicate than Mayo scissors.
