Blot's perforatorBlot, HippolyteThoms, Herbert (1885-1972)This is an instrument for removing a fetus. Hippolyte Blot of Paris designed this perforator for obstructed labor. The points of the blade are like diamond shaped spears. The spring-loaded handle of these perforators facilitates one handed use. After the fetus is perforated, compressing the handle engages the spring, which allows the blades to open and enlarge the perforation.still image
