Anatomical Silicone Models and Additive Manufacturing Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a process for producing highly realistic anatomical models using a direct 3D printing method with silicone rubber that can be cured by electromagnetic radiation, such as UV or visible light. The approach enables the creation of complex structures layer by layer, closely mimicking the mechanical, optical, and tactile properties of real human tissues. The system can use patient-specific medical scan data to produce personalized models for medical training, surgery planning, and patient communication.

Use CasesContent extracted from patent full text and abstract with AI.

• Training medical professionals in anatomy and surgical techniques using realistic models.
• Planning and practicing complex surgeries with patient-specific models.
• Demonstrating and illustrating medical conditions or procedures to patients for better understanding.
• Testing and evaluating new medical instruments or procedures in a controlled, realistic environment.
• Producing prototypes or custom implants, prosthetics, and epitheses based on individual patient data.

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced realism in anatomical models for training, due to the ability to closely simulate tissue properties (hardness, elasticity, color, etc.).
• Direct 3D printing eliminates the need for time-consuming and costly mold-making or casting steps.
• Capability to manufacture highly complex or delicate anatomical structures (e.g., hollow organs, branched vessels) that are challenging or impossible with traditional methods.
• Customization of models according to specific patient data, supporting personalized medicine and improved surgical outcomes.
• Efficient production workflow from digital scan to physical model, reducing lead times and manual labor.
• Multimaterial printing enables different tissue types (bone, muscle, skin) to be represented with appropriate properties in a single model.

Patent Abstract

The invention relates to a process for the additive manufacturing of an anatomical model using a 3D printing apparatus. The process is characterized in that at least one silicone rubber composition crosslinkable by means of electromagnetic radiation is used as the printing material. Layerwise application of the printing materials additionally allows the manufacture of complex anatomies. The anatomical models thus produced are particularly realistic and can be used by medical personnel for example for training, practicing surgical techniques, illustrating complex symptoms, or for patient-personalized preoperative surgery planning. The invention further relates to the anatomical models manufactured by the abovementioned process.
