3D scanning and Printing
One of the most critical parts in prosthetics is getting a good impression of the patient's residual limb. There are many ways to achieve this, but one size does not fit all. Casting a patient is good in some instances, but in others, to achieve the most accurate results, 3D scanning is the best choice. At Nextremity we utilize casting, duplicating, and 3D scanning to achieve the best results, and the key is to know which is best to use at each time.
3D scanning give an extremely accurate and quick digital replica of the patient's limb. This digital file is the modified on a computer to apply the correct pressures and reliefs. Once this file is modified, there are two methods of creating the socket for fitting. Traditionally, the model was sent to a 3D carver, and a foam duplicate of the lib would be carve into a block of foam. This foam was then used to thermoform, or wrap in melted plastic, to create the socket.
At Nextremity, we also have the ability to utilize 3D printing to achieve this. This can reduce time and allow for more fine tuning of the material properties of the prototype socket. 3D printing can also be used to create final decorative accents to a device if the patient desires.
These are just a few examples of how Nextremity utilizes technology to create a better patient experience.
