PROSTHESES

3D Prostheses Templates –

(TLT- True life templates) 

 The ability to plan surgery in 3D greatly enhances the capabilities and performance of the surgeon.  However, access to 3D models of arthroplasty prostheses is restricted due to the potential theft, or unauthorized copying of such critical and valuable modelling data.

To address this, True Life Anatomy have introduced a system to create a secure encapsulation of the 3D prosthesis information in an accessible, but non-distributable encrypted and protected digital format.

As part of the TLT process, the 3D data (typically an STL file) is significantly altered and then encrypted in such a way that it can only be viewed within the TLA Animator templating and virtual surgery environment. The process of complex and variable lock and key plus high level encryption in a non-distributable format allows the sharing of valuable 3D prosthesis data in a secure system, with the ability to save screen images, but without the ability to export, store or otherwise manipulate the critical and valuable 3D prosthesis data.

There are two level of secure TLT encapsulation (Patents pending):

• TLT(L) – this process disrupts and alters the data file and then high level encrypts the data in such a way that it can be decrypted and repaired only in the TLA Animator templating and virtual surgery environment. Such files can be accessed and stored on local folders or databases for immediate or subsequent use, by using the decryption and repair process.    Link to TLT-Local
  
• TLT (0) – this is a much higher-level security where the same file disruption and encryption process is used, but with additional decryption authorization linked to a registered user details and a specific one-off decryption code. Once a registered user has identified the desired prosthesis, the prosthesis vendor performs the secure encapsulation packaging and export the protected file to the requesting surgeon. The vendor also sends a unique and time limited decryption code which allows the completion of the decryption process.  Such 3D data files can only be viewed real time within the TLA Animator templating and virtual surgery environment, and saved as 2D screen captures or animations.  A record of the download pathway and details of the prosthesis can be saved to allow the planning process to be repeated, but re-importing the 3D prosthesis data requires a new unique real time secure pathway.  TLT(0) files cannot be stored locally.
