Which tool is primarily used to hold sutures during surgical procedures?

The Gillies needle holder is specifically designed for gripping and manipulating suture needles during surgical procedures. Its structure typically features a locking mechanism and a tapered tip, which allows the veterinary professional to securely hold the needle while suturing tissues. This precision is vital during surgery, as it ensures that the suturing process is controlled and that the needle can be accurately placed, reducing the risk of complications.

In contrast, the other instruments listed serve different purposes in surgical procedures. The Lagenbeck retractor, Travers retractor, and Gosset retractor are all designed for different kinds of tissue manipulation and visibility, specifically to hold back tissues or organs to give the surgeon a better view of the surgical site. While they play critical roles in surgery, they are not intended for the specific task of holding sutures, which is the primary function of the Gillies needle holder.
