This is a surgical instrument devised by London surgeon John Woodall to treat severe cases of constipation. This life-threatening condition was thought by Woodall to be a result of scurvy. But it is more likely the result of taking large amounts of the pain-killer laudanum.
In 1609, Woodall sent a fully-equipped surgeon’s chest to the Jamestown colony.
