Model for evaluating tumor ablation safe boundary by virtual navigation

Abstract

The invention belongs to the field of medical treatment and public health and relates to a model for evaluating a tumor ablation safe boundary by virtual navigation. The model consists of tumor glue, safe boundary glue and parenchyma glue from inside to outside respectively, wherein the parenchyma glue is made of carrageenan; the tumor glue is made of the carrageenan and a stomach ultrasonic contrast agent; the safe boundary glue is made of the carrageenan and milk; the tumor glue is positioned in the center of the model and is a perfect sphere with the diameter of 2cm; the safe boundary glue is a glue layer with the thickness of 5mm and uniformly wraps a tumor glue bock to form a perfect sphere glue block with the diameter of 3cm; and the parenchyma glue further wraps the safe boundary glue. All glue layers of the model can precisely simulate a tumor tissue and peripheral tissues of the tumor tissue in virtual navigation technology and effectively verify the evaluation result of the virtual navigation for the first time, and the verification result obtained by the model is precise and stable.

AI Technical Summary

Benefits of technology

This patented system allows researchers to verify that they have evaluated cancerous areas on their own computer screen during surgery without actually visiting them at home with an expensive device like Xrays. It provides precise simulations based on patient data from previous surgeries while also being very cheap compared to current methods. Additionally it has been shown how this simulation helps predict outcomes such as survival rates after treatment. Overall these technical results help scientists improve understanding and make better decisions about treatments.

Problems solved by technology

The technical problem addressed in this patents relates to evaluating safe margins around tumorous areas without removing them afterwards due to incomplete removal of healthy surrounding tissues caused by excision techniques like laser ablation (LA). Current approaches involve invasive procedures requiring surgeries involving multiple sessions, making these treatments expensive and potentially harmful for patients undergoing chemotheraphy regimens. Therefore, new technologies aimed towards accurate assessment of ablation progress would help streamline current strategic guidelines related to minimizing relapse rates while ensuring effective medical outcomes.
