Computer-aided liver operation planning three-dimensional modeling system

Abstract

The invention relates to the technical field of operation modeling, and discloses a computer-aided liver operation planning three-dimensional modeling system, which comprises an operation process rehearsal system and an operation positioning system, and is characterized in that the operation process rehearsal system comprises an operation process broadcasting system, an operation three-dimensional modeling system and an operation process teaching system; related examination data are imported into the operation process rehearsal system, the system calculates and analyzes the data, the operation three-dimensional modeling system carries out three-dimensional reconstruction on a preoperative two-dimensional CT / MRI image, and the operation process teaching system is divided into operation rehearsal and operation implementation process teaching. According to the system, various data are calculated and analyzed through the system, the volume of the liver to be resected and the volume of the remaining liver are calculated, three-dimensional space distance data of tumors and important blood vessels are measured in real time, the volume of the selectively resected liver is calculated, and the operation implementation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of surgical modeling, in particular to a three-dimensional modeling system for computer-aided liver surgery planning. Background technique [0002] When it comes to liver surgery, many people think of the shadow of the knife on the operating table. The surgical patient suffers from huge incision pain and cannot eat for several days after the operation. The classic "Mercedes-Benz" mark-like scars are often itchy and painful. These descriptions of traditional liver surgery are not wrong. Traditional surgery is indeed a double-edged sword. With the continuous improvement of technology and medical equipment, the proportion of minimally invasive surgery is getting higher and higher. At present, in some large hospitals with relatively good minimally invasive surgery, about half of abdominal surgery can be done under laparoscopy, and the proportion of laparoscopic liver surgery It is also getting higher and higher...

AI Technical Summary

Problems solved by technology

[0003] The blood circulation of the liver is very rich, and it is supplied by the portal vein and the hepatic artery: 1 / 4 of the blood flowing into the liver comes from the hepatic artery, which mainly supplies the oxygen needed by the liver, and the other 3 / 4 comes from the portal vein (supplied by the stomach, intestines, spleen, etc.) , pancreas and other visceral veins), it transports various nutrients and harmful substances from the digestive tract into the liver, and after being processed by the liver, it enters the systemic circulation. Due to the complicated distribution of blood vessels around the liver, if the peripheral blood vessels cannot It is difficult to design a reasonable incision position in advance, which reduces the efficiency of operation and prolongs operation time.
