A Spackmann Cannula is used to inject dye into the uterus. Whilst reusable versions exist, they are very difficult to clean effectively and economically. This single-use version is guaranteed sterile, and the novel clamp makes it significantly easier to use. The form of the handle has been articulated with strengthening ribs that also form a single line-of-draw opening to allow the steel tube to pass through. The functional improvements and aesthetics make this device unique within the field. Design Registered.
