Clamps: Clamps are used to occlude blood vessels or to grasp tissues. Common types include:

   * Kelly Clamps:  General-purpose clamps with teeth.
   * Crile Clamps:  Similar to Kelly clamps but with a curved shape.
   * Kocher Clamps:  Have teeth at the tip and a ratchet mechanism for secure clamping.

Retractors: Retractors hold back tissues to improve surgical access. Examples include:

   * Army-Navy Retractor:  A simple handheld retractor.
   * Deaver Retractor:  A larger, curved retractor for deeper retraction.
   * Gelpi Retractor:  A self-retaining retractor with multiple prongs.  Proper retraction is essential for visibility, just as clear Chart Patterns are essential for identifying trading opportunities.

Needle Holder: Used to grasp and manipulate needles during suturing. Needle holders have a textured surface to prevent the needle from slipping.
Suture Scissors: Used to cut suture material.
Hemostats: Used to clamp blood vessels to stop bleeding. Often referred to as "Kelly" clamps.
Electrocautery Device: Uses high-frequency electrical current to cut tissue and coagulate blood vessels. This minimizes blood loss and allows for precise dissection. Understanding electrocautery is similar to understanding the impact of Economic Indicators on market trends.

Materials Used in Surgical Instruments

The materials used to manufacture surgical instruments are carefully selected for their properties, including strength, corrosion resistance, biocompatibility, and sterilizability.

Stainless Steel: The most common material for surgical instruments. Different grades of stainless steel are used, with 304 and 316 being the most prevalent. 316 stainless steel is more resistant to corrosion, making it ideal for instruments used in sterile environments.
