Myoma screw, steel, by Alexander and Fowler of Liverpool, late 19th century
A myoma is a benign (non-cancerous) tumour in the muscle of the uterus. This myoma screw is used in surgery to remove such fibroids. It can be done abdominally or via the vagina. The fibroid is ‘screwed’ and clamped before removal. The myoma screw is almost crude in its simplicity. It has a straight shaft with an oval handle and a corkscrew head. It was made by Liverpool-based instrument makers Alexander and Fowler towards the end of the 1800s.
