Study Notes
Instrumentation
- Three finishes for surgical instruments: Highly polished, Satin (reduces glare), and Black (Ebony) for laser use.
Metals Used
- Surgical Stainless Steel is most commonly used due to its corrosion resistance. Titanium is also notable.
Cutting/Dissecting Instruments
- Types include Scalpels, Knives, Osteotomes, Gouges, Curettes, Roungers, Scissors, and Chisels, all designed for various cutting needs.
Specific Instruments
- Chisels: Wedge-shaped instruments for cutting or shaping bone.
- Curettes: Used for scraping away bone or cartilage; may have a cup or open wire for scraping.
- Scalpels: Feature detachable, disposable blades with non-disposable handles.
- Knives: Typically interchangeable with scalpels, available as disposable or reusable units.
Scalpel Handles and Blades
- #10, #11, #12, and #15 Blades fit Handles: #3, #7, #9.
- #20 - #29 Blades fit Handle: #4.
- #4 Handle: For cutting heavy tissue or bone.
- #7 Handle: Thinner, used for smaller areas.
- #3 Handle: Available long or short (5.5" to 8.5").
Retractors and Viewing Instruments
- Designed for exposure of operative sites, may be handheld or self-retaining.
- Balfour Retractor: Abdominal use, with interchangeable blades.
- Weitlaner Retractor: Superficial use, self-retaining; available with sharp or dull prongs.
- Bookwalter Retractor: Universal system for deep abdominal retraction.
Suturing Instruments
- Needle Holders used for holding curved suture needles; types include:
- Baumgartner: Short jaws with a groove.
- DeBakey: Fine jaws, commonly used in vascular procedures.
- Mayo-Hegar: Designed for heavy suture needles.
- Webster: Fine needles, typical in plastic and ENT surgeries.
Suctioning Instruments
- Serve to remove blood and fluids for better visualization during surgery.
- Frazier Suction: Small quantities, used primarily in ENT procedures.
- Poole Suction: For large quantities; its parts must be accounted for in instrument counts.
Instrument Care and Handling
- Divided into three phases: Preoperative, Intraoperative, and Postoperative.
- Preoperative care includes gathering instruments per surgeon's preference.
- Intraoperative care requires anticipating the needs of surgical staff.
- Postoperative care involves cleaning, inspecting, reassembling, sterilizing, and storing instruments.
Sterilization
- Steam sterilization is preferred for speed and cost-effectiveness. Other methods include ethylene oxide and vaporized hydrogen peroxide.
Instrument Sets
- Sets are assembled, sterilized, and standardized per facility requirements. Examples include Gallbladder, Hemorrhoid, and Laparoscopic sets.
