Interchangeable Tips: The set includes a single, solid metal handle and multiple interchangeable trocar pins of varying diameters (typically ranging between 1.7mm and 6.0mm)

Threaded Base: Each trocar pin features a threaded base that allows it to screw securely directly into the top of the handle

Three-Cornered Point: The tips are designed with sharp, triangular (three-cornered) points to cleanly puncture and tunnel through soft tissues.

Protective Guard: The hollow sleeve included in the set acts as a guard to cover the sharp tip when the tool is not in use
