Hemostats Flashcards

Hemostats Overview

• Hemostats function as tissue forceps, utilized primarily to control bleeding.
• They crush tissues and vessels, effectively stopping hemorrhages during surgical procedures.

Usage of Curved Hemostats

• Curved hemostats are pointed upwards when in direct use on the patient, facilitating access to the surgical site.
• When handing the instrument to a surgeon, the curved hemostat is oriented downwards for safety and ease of transfer.

Types of Hemostats

• Halsted Mosquito Forceps: Designed for small vessel occlusion; features transverse striations throughout the inner jaws for enhanced grip.

• Kelly Hemostatic Forceps: Suitable for larger blood vessels; has transverse striations that extend halfway down the jaws.

• Crile Hemostatic Forceps: Used for larger vessels and tissue grasping; characterized by transverse striations running the full length of the inner jaw.

• Rochester-Pean Hemostats: Ideal for grasping larger vessels and hollow tissue structures; longer and wider jaws provide greater clamping force than Crile forceps.

• Rochester-Carmalt Hemostats: Designed to grasp larger vessels and hollow organs before ligation; features crosshatching on the tips for aggressive crushing capabilities.

• Rochester-Ochsner Hemostats: Similar to Pean hemostats but include teeth on the tips (one tooth on one tip and two on the other) allowing for a firmer grip.

• Ferguson Angiotribe: A heavy-duty instrument used for arresting hemorrhage; distinguished by deep, longitudinal grooves and extensive crosshatching for a strong clamping action.
