This trephine was a hand-powered drill with a cylindrical blade that was used to bore into the skull. The spike in the center was used to start the procedure and to hold the blade in place while cutting.
Hernia Tool (1850s)
This unique tool was used after the restoration of a hernia. It was inserted into the body near the affected area and left there for a week to produce scar tissue that would help seal off the hernia.
Hemorrhoid Forceps (1800s)
These forceps were used to grasp a hemorrhoid between the blades and apply pressure to stop the blood supply, causing the hemorrhoid to drop off.
Skull Saw (1830s-60s)
This hand-cranked saw's blades were used to cut through sections of the skull, allowing for access by other instruments.
Cervical Dilator (1800s)
This instrument was used to dilate a woman's cervix during labor, with the amount of dilation measured on the scale by the handle. Such dilators fell out of favor because they often caused the cervix to tear.
Amputation Knife (1700s)
Knives used for amputations during the 18th century were typically curved, because surgeons tended to make a circular cut through the skin and muscle before the bone was cut with a saw. By the 1800s, straight knives became more popular because they made it easier to leave a flap of skin that could be used to cover the exposed stump.
