3D full silica gel heart model

Abstract

The invention relates to a 3D full-silica gel heart model, which comprises a right atrium, a right ventricle, a coronary sinus, an upper vena cava, a lower vena cava, an anterior ventricular sulcus vein, a posterior ventricular sulcus vein, a cardiac great vein, a cardiac vein, a cardiac posterior vein and a pulmonary artery, and is formed by adopting full-silica gel printing after 3D modeling. The heart model provided by the invention comprises all heart-related vein circulation systems and a complete right heart system, and is an intracavitary anatomy three-dimensional model comprising a right heart system and peripheral main vein vessels and pulmonary artery vessels. By simulating real blood flow and combining cardiac impulse simulation of a pulsating pump, a clinician can obtain the same operation feeling as in-vivo operation of a real patient in operation practice of a pacemaker electrode lead implantation operation and a double-ventricle pacing electrode lead implantation operation.

Description

technical field [0001] The invention relates to the technical field of medical models, in particular to a 3D all-silica gel heart model. Background technique [0002] At present, in clinical practice, doctors mainly understand and learn biventricular synchronous pacing (CRT) and pacemaker lead implantation surgical techniques through observation of operations and animal experiments. However, the method of surgical observation cannot be used for hands-on operation. For each step in the operation, it depends entirely on observation and imagination, and it is impossible to intuitively understand it through operation. There is a big difference from the human body, and it is impossible to achieve complete real practice, and the difference in the heart structure of experimental animals and heart failure patients is even greater, which has limited benefits for doctors to improve their surgical skills. [0003] Currently, various biventricular synchronous pacing lead implantation s...

However, the method of surgical observation cannot be used for hands-on operation. For each step in the operation, it depends entirely on observation and imagination, and it is impossible to intuitively understand it through operation. There is a big difference from the human body, and it is impossible to achieve complete real practice, and the difference in the heart structure of experimental animals and heart failure patients is very large, which has limited benefits for doctors to improve their surgical skills

[0003] At present, various biventricular synchronized pacing lead implantation surgery learning methods used in clinical practice are also limited by capital expenditure and equipment conditions, and cannot be carried out on a large scale.
