A suture passer is a specialized surgical instrument used to facilitate the placement of sutures in various medical procedures. It helps surgeons thread sutures through tissue layers, making the stitching process more efficient and precise. Suture passers are commonly used in minimally invasive surgeries, where access to the surgical site is limited. These instruments come in various designs, including straight and curved types, to accommodate different surgical needs. Some suture passers are equipped with features like locking mechanisms to secure the suture during placement. They are essential tools in surgeries involving tissue repair, orthopedics, and laparoscopic procedures.
