Abstract
An instrument to remove stones from the human body such as stones in the gall bladder or kidney. An intracavitary tube is inserted in the organ where calculus is produced having an explosive charging chamber at the tip thereof. This explosive charging chamber is formed by a lid made of rigid material like metal except a fragile part made of less rigid materials and a triggering device for igniting the explosive from outside. The intracavitary tube is inserted into the organ, and the explosive charging chamber is brought near or in contact with the calculus, and then exploded to inflict a destructive force upon the calculus to crush it into small pieces, and the crushed small pieces are then eliminated from the human body.
