General information

Short Summary
A German university offers a new method to determine object positioning in surgical training or other applications. Advantages of the 3D printed models include time and resource efficiency. A prototype is available. Partners from medical industry are sought for licensing agreements.
Full Description
Evaluating the exact positioning of a guide wire in a 3D-printed training model, e.g. placement of a Kirschner wire (K-wire) in reverse shoulder arthroplasty (RSA), is often very complicated and requires complex methods such as CT imaging. These methods are time-consuming and expensive.

In order to improve the processes, inventors of a German university developed a 3D-printable three-dimensional target system for training purposes, that enables a quick and resource-saving evaluation of the exact positioning in 3D-printed models.

With their invention, the university can offer a method of providing modified model data of an object.

This includes:

• obtaining model data of the object
• positioning at least one processing line through the object, wherein the processing line represents a trajectory of a tool to be introduced into the object
• positioning a first target disk and a second target disk, spaced apart form one another, in the object, along the processing line
• defining an exchange volume comprising the first target disk, the second target disk, a portion of a surface of the object surrounding the intersection of the processing line with the surface of the object, wherein the exchange volume is configured for attachment to the object
• and obtaining the modified model data for the manufacture of a modified object, wherein the modified model data comprises model data for the exchange volume and model data for the remaining part of the object.

It is possible to adapt the application in numerous medical fields but also other areas are conceivable.

A prototype is available. The figure below shows a modified object including a main body and an exchange volume configured for attachment to the main body, wherein the exchange volume comprises a first target disk and a second target disk, spaced apart from one another.

Licensees from medtech industry are sought.
Advantages and Innovations
