Embodiment Construction

[0034] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0035] To realize the present invention, it is necessary to connect the auxiliary pipelines of foreign animal organs (such as heart, liver and kidney, etc.) with the corresponding pipelines of the organ perfusion system through vascular magnetic anastomosis technology or other pipeline connection techniques (such as cuff method + suture ligation and fixation) , to provide it with a suitable osmotic pressure and non-toxic and harmless colored perfusate (used to simulate blood) for organ tissue cells, and the driving force provided by the pump set in the organ perfusion system realizes the perfusate flowing in / out of the blood smoothly The circulation in the tract can be sensed and adjusted by the flow rate / blood pressure sensory-feedback adjustment system to realize the high simulation of visceral perfusion. At the same time, the intraoperative bl...

Abstract

An organ perfusion system for surgery simulation trainers comprises a perfusate collection tank, a simulation tube, a pump unit and a flow velocity/ blood pressure feel-feedback regulation system, wherein the perfusate collection tank is used for maintaining a grown form of the organ in a short time; the simulation tube is connected with a tube of the organ subjected to the surgery correspondingly; the pump unit is connected between the perfusate collection tank and the simulation tube and provides driving force enabling the perfusate to flow in the simulation tube; the flow velocity/ blood pressure reception-feedback regulation system comprises a flow velocity/ blood pressure receptor arranged at the connection position of the simulation tube and the tube of the organ subjected to the surgery, an external control system and a flow regulation system in the pump unit and controls power of the pump unit according to data collected by the flow velocity/ blood pressure receptor, and therefore, blood circulation in the physiological status can be simulated. The organ perfusion system for the surgery simulation trainers can be applied to all the surgery simulation trainers to simulate haemodynamics of the organ in the physiological status.

Description

technical field [0001] The invention relates to the field of medical equipment, and relates to an organ perfusion system, in particular to an organ perfusion system used in a surgical simulation trainer. Background technique [0002] Current surgical simulators can be divided into three categories: mechanical, hybrid or virtual reality. Mechanical trainers have the following advantages: more accessible, practical, reusable, easy to teach and cost-effective. The disadvantage is that it lacks reliability, validity, and strict and objective evaluation, and cannot realistically imitate the operation of various organs under surgical conditions, and the degree of scene restoration is low. The virtual reality simulator uses three-dimensional sensing technology to perform basic surgical operations such as incision, suture, and knotting on virtual human organs and practice various surgical techniques, and can monitor the operator's movements in real time and continuously. Records, ...
