Novel Polysaccharide-derived Fixation Device for Anterior Cruciate Ligament (ACL) Reconstruction Team #13 Weekly Meeting Alexander Werne, Derek Holyoak, Benjamin Roberts Faculty Advisor Dr. Krystyna Gielo-Perczak Clients Dr. Sangamesh Kumbar Gloria Kolb

Current Plans Use Compression Molding for the interference screw Design mold of screw in SolidWorks Machine mold out of Teflon ◦ Matthew Harmon from UCHC is a good source for molds Once mold is complete, use molding device at UCHC to fabricate screw from novel material

Current Plans Use 3-D printing for hamstring tendon casing ◦ Tom Mealy from ME department is a good source for 3-D printing Search for possibly ways of fabricating the tendon casing out of novel material

Progress with Compression Molding Dr. Kumbar’s Mystery Device ◦ Looks similar to the device shown to the right ◦ Contains a heating plate with temperature gauge ◦ Contains a lever with pressure gauge ◦ Can be used to manually compress any type of mold

Progress with Creating Mold Successfully “shut off” surfaces Identified “Pull Direction” Created a “Parting Line” Need to create “Parting Surface,” but have been unsuccessful due to geometric conditions

Progress with 3-D Printing Ben is in touch with Tom Mealy ◦ Trying to set up a good time to print our hamstring tendon casing

Future Work Finish creating mold in SolidWorks If problems persists, contact Matthew Harmon Visit UCHC on 2 / 22 / 13 Set up date for 3-D printing
