Tech in Surgery Prep / Unit 12 TSC 279 short lesson, about 20 seconds
Serrations, Teeth and Jaws
Captions available
The idea
The working surface of a grasping instrument decides how it treats tissue: serrated, toothed or smooth.
In practice
Serrations add friction without piercing; teeth give a firm hold on tough tissue but can damage delicate tissue; instruments are described as traumatic or atraumatic accordingly.
Where people slip
Teeth and serrations are different features; reaching for the wrong one can tear tissue.
