A unique surgical tool called the Transplant Donor Sternal Spreader-Adult is made to provide the best possible exposure during organ procurement procedures. Its sharp side blades, which are made of surgical-grade stainless steel, are 7/8 inch (2.3 cm) wide by 1 inch (2.5 cm) deep, with a maximum spread of 7½ inches (19 cm). The retractor is securely fastened in the donor's sternum by the Morse-style blades, which feature a massive spike and a noticeable lip to provide maximal spread without slippage.
