Definition

1. Noun:
   • A specific type of knot used in surgery: A "surgeon's knot" is a secure knot, often a modified square knot or reef knot, characterized by an extra initial twist or turn.

Advanced Usage

• Technical Application: In surgical contexts, the term specifies the knot's function for tying off blood vessels or closing wounds. Its primary advantage is its resistance to slipping under tension while being tied.
  • The surgeon's knot is particularly useful when working with slippery monofilament suture material.
