Embodiment Construction

[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following embodiments are combined with the accompanying drawings to illustrate the present invention in detail.

[0028] figure 1 It is a structural schematic diagram of the training model for endoluminal treatment of ascending aortic root in the embodiment of the present invention.

[0029] Such as figure 1 As shown, the ascending aortic root endovascular treatment training model 100 in this embodiment is used to allow medical personnel to perform aortic valve interventional treatment training and to test the interventional stent and its delivery system, including a heart model 10, a heart model fixed stent 20. The liquid circulation system 30 and the liquid exchange part 40.

Abstract

The invention provides an ascending aorta root intracavitary therapy training model, which comprises a heart model, a heart model fixing support frame and a liquid circulation system, wherein the heart model is provided with a heart body and an intervention entering device; the liquid circulation system is provided with an aorta model, a vein model and a pulsating pump; the intervention entering device comprises a silicone tube sleeve, a silicone tube and an extrusion part; one end of the silicone tube sleeve is a cardiac apex connecting end; a first intervention entering hole is formed in theend surface; the other end is provided with a silicone tube placing hole; internal screw threads are formed on the hole wall of the silicone tube placing hole; the extrusion part is connected with the silicone tube sleeve through screw threads; a second intervention entering hole is formed in the end surface of the extrusion part, so that the extrusion part can extrude a silicone tube when beingscrewed into the silicone tube sleeve, so that the tube hole of the silicone tube is closed; and the extrusion part enables the tube hole to recover the open state when being unscrewed from the silicone tube sleeve, so that a conveying system for intervention can reach an aortic valve model part sequentially through the second intervention entering hole, the tube hole of the silicone tube and thefirst intervention entering hole, so that medical personnel simulate interventional therapy operation training.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a training model for intracavity treatment of ascending aortic root. Background technique [0002] Stenosis or insufficiency of the aortic valve will cause increased heart load. When the disease progresses to a certain extent, heart failure symptoms such as decreased heart function, decreased physical strength, palpitations, chest tightness and discomfort will appear, which will affect the quality of life of the patient. The prolongation of the disease and the aggravation of the disease will even affect the life of the patient. [0003] In traditional aortic valve surgery, the patient needs to undergo thoracotomy, open the heart, and repair or replace the valve under extracorporeal circulation. Generally, the operation time is as long as 3 to 4 hours, which makes the patient need to endure huge trauma, and critically ill patients are not sensitive to surgery. The tolerance is lo...
