Umbilical Cord Scissors
Umbilical cord scissors are used to cut the umbilical cord during childbirth. They are designed for a clean and safe cut.
Tenaculum
Tenaculums are gynecological instruments used to grasp and manipulate the cervix during procedures like IUD placement or cervical biopsies.
Cervical Biopsy Punch
Cervical biopsy punches are used to obtain tissue samples from the cervix for diagnostic purposes. They come in various sizes for different applications.
Vaginal Episiotomy Knife
Vaginal episiotomy knives are designed for episiotomies in obstetrics. They allow for controlled and precise incisions during childbirth.
