Preoperative auxiliary device for liver tumor thermal ablation operation

Abstract

The invention relates to a preoperative auxiliary device for thermal ablation of liver tumors, which is provided with a head-mounted VR display; a head-mounted in-ear earphone is installed on the head-mounted VR display; at least one locator; at least one control handle; and a locator , The control handle is wirelessly connected to the computer. The invention is more convenient to use, and doctors can design and plan different surgical plans multiple times with the assistance of the system, and perform simulated operations, select a more reasonable plan among them, and improve the success rate of the operation; compared with traditional two-dimensional image pictures , medical images in virtual reality are more realistic, doctors can diagnose and analyze patient image data from multiple angles, and at the same time, virtual reality technology can realize the interaction between doctors and image data.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine, in particular to a preoperative auxiliary device for thermal ablation of liver tumors. Background technique [0002] At present, for clinical liver thermal ablation surgery, doctors often can only rely on two-dimensional image data such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) when planning preoperatively To observe liver lesions, and these two-dimensional image data provide only a series of separated images, doctors can only rely on their own clinical experience, combined with two-dimensional image data to construct three-dimensional image information of lesions in their minds, this method is extremely It depends on the personal experience and skills of doctors, and it is inevitable that there will be deviations in the way of thinking of different doctors. Doctors subjectively predict the location of the lesion and the deterioration of the lesion, ...

AI Technical Summary

Problems solved by technology

Doctors subjectively predict the location of the lesion and the deterioration of the lesion, and then make corresponding preoperative planning, lacking intuitive and accurate analysis

Once the location of the lesion is wrongly predicted, or the judgment of the deterioration of the lesion is biased, the corresponding preoperative planning will also be wrong, which will lead to an unsmooth operation process, the final surgical effect cannot meet expectations, and the treatment effect is not good. If it is not thorough, it will affect the curative effect and even cause serious complications, which will bring unnecessary pain to the patient

[0003] To sum up, the current preoperative planning of thermal ablation therapy relies on the skills of doctors and is highly subjective. This is the shortcoming of the existing technology, mainly because it only uses two-dimensional images without three-dimensional modeling, directly Affect the efficacy of thermal ablation surgery
