Question

What is the main difference between these two instruments?

vs

Answer

The first instrument is an Allis clamp, which has sharp teeth and can crush tissue.  It is used for grasping fascia or tissue that needs to be removed or manipulated during procedures.

The second instrument is a Babcock forceps,  which is non-toothed and has a wider grasping surface.  These forceps do not damage tissue and are considered non-crushing and can be used to grasp delicate tissue.  The head of the forceps is open and helps for rapid identification.
