Latest Patents

One of Carl Nelson's latest patents is the Composite Allograft Press. This innovative device is designed to form a composite acetabular allograft cup for use in hip replacement surgery. The acetabular cup created by this press consists of bone cement and cancellous bone chips. The press features a two-piece mold that can be removed and is available in various sizes to accommodate different patients. A screw-type compression mechanism is utilized to shape the acetabular cup, while a compression gauge allows the operator to monitor the pressure applied, preventing excessive crushing of the cancellous bone chips. Additionally, breaking jaws are incorporated to separate the acetabular cup from the mold after the bone cement has set.

Another patent by Nelson is the Composite Allograft, Press, and Methods. This invention includes a loading frame and a two-piece mold to create a composite allograft, specifically an acetabular cup made from impacted cancellous bone chips and cement. The pressure is applied through a manually operated lever using a rack-and-pinion gear mechanism. Compression load switches indicate the correct loading to produce a composite allograft with a smooth inner surface primarily made of hardened bone cement material. The outer portion may exhibit limited cement extrusions, showcasing exposed cancellous bone surface. In surgical applications, the composite allograft is fixed in the acetabulum with bone screws to address acetabular defects.
