What is the primary function of Mayo-Hegar needle holders?

The primary function of Mayo-Hegar needle holders is indeed needle holding. These instruments are specifically designed to securely grasp and manipulate needles during suturing procedures. The design of Mayo-Hegar needle holders includes a ratchet mechanism, which allows for a firm grip on needles without slipping, providing the precision needed in surgical settings.

While some instruments may have multiple functions, Mayo-Hegar needle holders are singularly focused on securely holding needles. This specialization makes them essential for ensuring that surgical sutures are placed accurately and efficiently, which is critical for effective wound closure and minimizing patient complications. Other options mention functions that are relevant to different instruments; for example, holding sponges or retracting eyelids, which are functions of other surgical tools.
