A surgical retractor is a medical instrument used during surgery to hold back tissues, organs, or the edges of an incision. This provides surgeons with a clear view and access to the surgical site while keeping surrounding tissues safe.
🌟 Key Features
- Purpose: Exposure of operative areas, protecting tissues from damage.
- Material: Usually made of stainless steel or sometimes titanium for lightweight models; some disposable retractors use plastic.
- Design: Can be handheld or self-retaining, with prongs, blades, or hooks.
🩺 Common Types
- Handheld Retractors
- Simple design, held manually by the surgeon or assistant.
- Examples: Senn retractor, Richardson retractor.
- Used in general surgery, orthopedic procedures.
- Self-Retaining Retractors
- Stay in place without being held, using a ratchet or spring mechanism.
- Examples: Weitlaner retractor, Balfour retractor.
