A 10-inch needle holder is a surgical instrument used to hold, guide, and push a suturing needle during a variety of surgical procedures, such as wound closure, tissue approximation, and ligation. The larger 10-inch size is particularly useful for general surgery and when working with larger or heavier suture needles. 

Wound closure:

The primary function is to hold a needle securely to precisely stitch and close wounds to promote healing.

Tissue approximation:

It helps bring the edges of tissue together during surgery to ensure proper healing and minimize scarring.

Hemostasis:

By holding the needle, it assists in placing sutures to control bleeding.

Ligation and re-anastomosis:

It is used in procedures that require reconnecting or closing vessels or ducts, such as tying off vessels or re-anastomosing them.
