Embodiment Construction

[0022] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, implementations of the application; and the structures shown in the drawings are only schematic and do not represent real objects. It should be noted that, based on these embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art belong to the protection scope of the present application.

[0023] Herein, the term "upper (end)" means the positional relationship toward the ceiling, but it does not mean that it must face a certain fixed direction in actual installation operation, but only to show the positional relationship or connection relationship between the various components. The direction indicated by the arrow in the catheter in the legend is the direction of liquid flow, which is formulated according to the direction of blood flow in th...

Abstract

The invention discloses an assisted teaching device for a cardiac interventional operation. The device comprises a fixed device, a near infrared scanning device, an information processing device, a display device and an extracorporeal circulation device; the fixed device comprises a fixed bracket and a distance adjusting device; the near infrared scanning device comprises a tower crane, a near infrared laser emitter and a near infrared laser receiver, and a motor is arranged in the tower crane; the information processing device is used for processing and converting scanning information into aDSA image; the display device is used for displaying and simulating the DSA image; and the extracorporeal circulation device comprises an atrium dextrum catheter, a ventriculus dexter catheter, an atrium sinistrum catheter, a ventriculus sinister and a pump. By utilizing the imaging of the near infrared light, the DSA imaging can be simulated through computer software synthesis, thereby avoiding unnecessary radiation damage of an exerciser in the operation exercise process; and the human body cardiac blood flow process can be simulated by utilizing the extracorporeal circulation device, so that the operation exercise becomes more realistic, and the teaching quality and level are improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an auxiliary teaching device for cardiac interventional surgery. Background technique [0002] With the continuous development of cardiac surgery today, the operation method is gradually developing towards the direction of minimal invasiveness, which means that more and more doctors need to practice interventional surgery continuously. Therefore, how to simulate X-ray imaging in the usual auxiliary teaching model becomes critical, and near-infrared lasers have certain penetration, especially for transparent materials. After retrieval, there are 41 domestic published patent documents on "surgical assisted teaching", involving oral cavity, artificial abortion and other fields, among which CN104966450A discloses a medical operation teaching equipment, including surgical equipment and auxiliary equipment, arranged on the upper end of the operating table base Ther...
