Technology
CAD-CAM is the latest wave of technology to hit the prosthetics industry. The system uses computer digital technology to create a near perfect, custom fit of a socket to a residual limb. St. Petersburg Limb & Brace was one of the first companies to use computer aided design fabrication in Florida.
One of the most common complaints among amputees is a poorly fitting prosthesis. CAD –CAM (computer-aided design, computer-aided manufacturing) increases the accuracy and efficiency of socket design. This allows up to produce a comfortable socket in a fraction of the time.
THE DIGITIZER: A Mechanical digitizer is used to take exact measurements of a negative cast by calculating spacing between geometric slices and capturing radial distances as the model spins. These measurements are converted to a shape, which can then be viewed on the monitor. The computer workstation enables the prosthetist to make precise modifications to the image being projected on the monitor from the digitizer. The prosthetist uses special Software and templates to modify the shape into a weight-bearing interface. This is the most critical step in the process, and an experienced prosthetist is a must. Once the shape is perfected, it is then sent to the carver.
THE CARVER: A machine that cuts the mold to the exact specifications sent to it by the Prosthetist. From this mold, the actual interface is made.
The imaging systems performs in a faction of the time it normally takes to fabricate and fit a prosthesis in the slower conventional method. This translates to quicker rehabilitation times and significant cost savings.
Technical innovations will continue to make artificial limbs more comfortable, efficient, and lifelike. You can depend on St. Petersburg Limb & Brace to continue to update their patients are such advancements in our field and provide the latest information as it develops.
