Automatic valve stent conveying system based on image segmentation

Abstract

The invention relates to an automatic valve stent conveying system based on image segmentation. The automatic valve stent conveying system is composed of remote control software, a mechanical arm and a stent conveying device. The remote control software comprises a parameter setting page, an ultrasonic image preselection marking page and a process control page, and remote connection is established between the remote control software and the conveying device and between the remote control software and the mechanical arm through Wi-Fi; the mechanical arm is a six-axis mechanical arm, and the position of the valve stent is adjusted in the operation process; and the stent conveying device is mainly used for carrying the compressed valve stent into the heart to complete releasing and fixing. The automatic valve stent conveying system has the advantages that the position of the conveying device, the mitral valve activity state, the artificial stent release stage and the like can be monitored in real time, corresponding information is fed back to a controller and the mechanical arm, implantation and release of the heart valve stent are completed in a highly-automatic and staged mode, the problems that an existing valve conveying system is low in controllability, accuracy and safety are solved, and meanwhile, an operator is protected from radiation hazards.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic valve stent delivery system based on image segmentation. Background technique [0002] Mitral regurgitation (MR) is the most common valvular disease, with an incidence of about 1.7% in the general population. According to statistics, there are about 20 million people in China suffering from severe mitral regurgitation. Severe MR will seriously damage the heart function and increase the risk of heart failure, thus threatening people's health and life expectancy. Among patients with severe MR who are not treated surgically, the mortality rate within 5 years is as high as 50%, and 90% of the surviving patients will develop to the stage of heart failure. [0003] In the current clinical practice, the research hotspot is transcatheter mitral valve implantation (TMVI). TMVI is a minimally invasive surgery in which an artificial valve is inserted into the heart t...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a device capable of real-time monitoring of the position of the delivery device, the activity state of the mitral valve, the release stage of the artificial stent, etc., and feed back the corresponding information to the controller and the mechanical arm. Complete the implantation and release of the heart valve stent in stages, solve the problems of low controllability, accuracy and safety of the existing valve delivery system, and at the same time protect the operator from radiation hazards An automatic valve stent delivery based on image segmentation system
