What is a primary use of Debakey tissue forceps?

Debakey tissue forceps are specifically designed for grasping fine tissue during surgical procedures. Their unique configuration allows for a secure grip on delicate tissues without causing significant trauma, which is essential in maintaining the integrity of the tissues being manipulated. The serrated edges of the forceps provide a non-slip hold, making them particularly useful for handling vascular or soft tissues where precision is crucial.

The other options refer to different surgical instruments and their functions. Making skin incisions is typically performed with a scalpel, cutting suture would involve scissors, and clamping major vessels is done with hemostats or clamps specifically designed for that purpose. Thus, the primary use of DeBakey tissue forceps is indeed to effectively grasp and handle fine tissues during surgery.
