Dissecting Forceps (According to Overholt No. 7)

Trocars

• Material: Generally made from stainless steel, ensuring durability and resistance to corrosion.
• Design:
  • Features a sharp, pointed tip for penetrating tissues.
  • Hollow shaft allows for the passage of other instruments or drainage.
• Function:
  • Primarily used in minimally invasive surgeries (e.g., laparoscopy) to create access points for surgical instruments.
• Sizes: Available in various diameters to suit different surgical needs.

Suction Tubes

• Material: Usually constructed from medical-grade plastic or stainless steel.
• Design:
  • Can be flexible or rigid, with varying lengths and diameters.
  • Often includes openings along the sides or at the tip for effective suctioning.
• Function:
  • Used to remove fluids, debris, or gases from surgical sites or body cavities.
• Applications: Commonly used in surgeries, wound care, and emergency medicine.

Cannulas

• Material: Typically made from stainless steel or high-quality plastic.
• Design:
  • Hollow tubes designed for insertion into the body.
  • May have a removable inner stylet for ease of insertion.
• Function:
  • Used for administering fluids, medications, or draining fluids from the body.
  • Applicable in various medical procedures, including intravenous (IV) therapy and airway management.

Valvular Suction Tube

• Material: Often made from medical-grade plastic or stainless steel.
• Design:
  • Features a one-way valve mechanism to prevent backflow of fluids.
  • Typically includes a soft, flexible tip for safe suctioning.
• Function:
  • Designed to efficiently remove fluids while preventing contamination or re-entry of fluids into the suction source.
• Applications: Commonly used in surgical procedures, especially in delicate areas where controlling fluid dynamics is critical.
