A tenaculum is a surgical instrument used for grasping and holding tissues during various surgical procedures, particularly in gynecology. It features a sharp, hook-like design that allows for secure traction on delicate tissues, such as the cervix or uterine lining. The tenaculum is essential for procedures like dilation and curettage (D&C) or hysteroscopy, providing stability and control while minimizing trauma to surrounding structures. Its design ensures effective manipulation and access during intricate surgical tasks.
