A needle holder is a surgical instrument used to securely grasp and manipulate needles during suturing procedures. It typically features a locking mechanism that allows the surgeon to maintain a firm grip on the needle while stitching tissues together. This tool is essential in various medical fields, including surgery and dentistry. Needle holders come in different sizes and designs, catering to specific surgical needs. Some models have curved jaws for better access in tight spaces, while others are straight for general use. Proper use of a needle holder enhances precision and control, contributing to successful surgical outcomes.
