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.
