Computer implemented planning and providing of mass customized bone structure

Abstract

A computer-implemented method, a system and a computer program is disclosed, which comprise virtual planning of a medical procedure of a patient. The medical procedure comprises providing a patient configured bone structure in a body portion of the patient. Based on an input of a final result of the medical procedure, the bone structure may be modified by various tools and methods, such a bone implants, bone distractive methods, etc. Production data based on the virtual planning is generated that is configured for subsequent use in production of the bone structure or a medical product, which medical product is devised for use in the medical procedure, and devised for arrangement in the patient for facilitating the medical procedure. The virtual planning of a medical procedure comprises providing position data for a position of at least a part of a prosthesis component in relation to the body portion, and virtual planning of a modification of a boundary surface at the body portion as a function of the position data.

Description

FIELD OF THE INVENTION[0001]This invention pertains in general to the field of medical procedures. More particularly the invention relates to computer implemented virtual planning of medical procedures involving skeletal adjustments.BACKGROUND OF THE INVENTION[0002]In WO07045000 methods, techniques, materials and devices and uses thereof are disclosed for custom-fitting biocompatible implants, prosthetics, and interventional tools for use on medical applications. The devices produced according to the disclosure of WO07045000 are created using additive manufacturing techniques based on a computer generated model such that every prosthesis or interventional device is personalized for the user having the appropriate metallic alloy composition and virtual validation of functional design for each use.[0003]However, the disclosure of WO07045000 allows only additive adjustments of a prosthesis to an existing skeletal situation, which is a serious limitation concerning the medical procedure...

AI Technical Summary

Benefits of technology

[0009]According to a second aspect of the invention, a system is provided. The system is devised for computer-implemented virtual planning of a medical procedure of a patient, which medical procedure comprises providing a patient configured bone structure in a body portion of the patient. In some embodiments, the system comprises a unit for generating production data based on the virtual planning, wherein the production data is configured for subsequent use in production of the bone structure or a medical product, which medical product is devised for use in the medical procedure, and devised for arrangement in the patient for facilitating the medical procedure. The system for virtual planning of a medical procedure comprises a unit for providing position data for a position of at least a part of a prosthesis component in relation to the body portion. Furthermore, the system comprises a unit for virtual planning of a modification of a boundary surface at the body portion as a function of the position data.

Problems solved by technology

However, the disclosure of WO07045000 allows only additive adjustments of a prosthesis to an existing skeletal situation, which is a serious limitation concerning the medical procedures that may be implemented.

However, planning of such distraction surgical processes is hitherto based on a trial and error principle, or very much dependent on the experience of the surgeon performing the distraction process.
