A tenaculum is a surgical instrument with sharp hooks that is used to hold tissues or manipulate a structure during medical procedures, such as in gynecology or eye surgery. It is also commonly used in obstetrics to grasp and position the cervix during procedures like cervical biopsy or placement of an intrauterine device (IUD). The tenaculum's sharp points provide a firm grip, making it easier for the surgeon to work with precision and control.
