Winter can jump and splash about just like any other dolphin, thanks to our continued relationship with Hanger Prosthetics and Orthotics, Inc. Winter’s prosthetic tail is becoming more and more comfortable and streamlined with every design. We strive to continue making improvements as this is a one-of-a-kind tail and the only one in the world!
The many steps to putting on Winter’s tail start with a “sock.” This is what we call the famous “Winter’s Gel.” The sock is a very soft rubbery material that has helped many veterans and amputees reduce the pain of their prostheses. The sock reduces skin friction and helps the tail stay on. Next the “cup” is placed just at the base of Winter’s peduncle, above the fluke. The cup is molded to fit the peduncle exactly. The main suspension strap is then secured. Next the sleeve is pulled over the entire tail to secure everything. And finally a newer feature to Winter’s tail, the rubber band, is placed right at the end of the tail, next to her body.
What are the changes compared to her last tail?
The cup that fits on the end of her tail has been modified to be deeper on the dorsal-ventral side and is thinner in general. The flukes are thicker at the leading edges and thinner at the trailing edges and the main suspension strap is lined with non-slip foam and is held together with velcro. The main lateral struts have embedded polypropylene rods. The tail also has stabilizing cross-member straps connecting to the cup which result in a double-tripod design.
What are the future tail modifications?
We are going to modify this prototype by removing the cross-member straps. The new tail will have the main lateral struts hinged closer to the main suspension strap, so the stabilizing cross-member straps will not be needed.
