Study Notes
Scalpels
- Scalpels are used for the precise division of tissues with minimal damage to nearby structures.
- Sharp cuts cause less trauma and heal faster in tissues like skin.
- Sharp cuts can cause significant bleeding in tissues like vascular areas.
- Scalpel handles come in two sizes: #3 (often called a small handle) and #4 (often called a large handle).
- Handles are designed to hold scalpel blades.
- Scalpel blades are numbered from #1 to #22, indicating size and shape.
- To apply a blade to the handle, use needle drivers to grasp the blade near the middle, ensuring the sharp edge faces away from you.
- The handle has small grooves that fit with the cut-out portion of the blade, ensuring a flush fit with no raised edges.
- To remove a blade, grip it with forceps or needle holders near the base of the blade, keeping the cutting edge facing away from your hand and body.
Scissors
- Scissors are used for cutting tissue, dissecting tissues, and cutting suture material.
- They must be kept sharp to avoid tearing tissue instead of cutting it.
- Scissors are available in various lengths and should only be used for their intended purpose.
- Scissors are classified by name or purpose.
Operating Scissors
- Operating Scissors are used to cut inanimate objects, such as gauze or suture material.
- They can be classified by the type of blade (straight or curved) and the type of tip.
Mayo Scissors
- Mayo Scissors are used to cut large tissue masses, cartilage, or other non-delicate tissue.
- They can be straight or curved.
- Mayo scissors are always blunt in the middle and round at the end, making them a Blunt Blunt scissor.
- Their blades are thick and approximately ½ the length of the instrument.
Metzenbaum Scissors
- Metzenbaum Scissors are used for delicate surgical dissection.
- They have fine blades that are approximately ¼ the length of the instrument.
- They have a long and thin shaft.
- They are considered a longer, more delicate scissor than Mayo scissors.
Suture Scissors
- Suture Scissors are used to cut and remove suture material.
- They have a notch on one blade that slips under the suture to pull it up.
