animal heart transient fixator

Abstract

The invention discloses an animal heart instant fixing device. The animal heart instant fixing device structurally comprises a handle and a heart fixing ring, wherein the handle is composed of a first handle and a second handle; a through hole is formed in the upper end of the first handle; an inserting sheet is arranged at the upper end of the second handle; the inserting sheet is inserted into the through hole; the lower end of the first handle is crossed with the lower end of the second handle; the heart fixing ring is in an oval shape formed by bending a steel wire with a round cross section; two free ends of the heart fixing ring are connected with two free ends of the two crossed handles. The fixing device can be used for finishing heart operation in a short time, the stimulation time on a heart is shortened, and the death rate in intraoperative and postoperative processes of animals is reduced.

Description

technical field [0001] The invention relates to a fixator, in particular to an animal heart instantaneous fixator. Background technique [0002] In the field of clinical and basic research on cardiovascular diseases, it is indispensable to conduct in vivo animal experiments through small animals (large and mice), especially the application of rats to prepare ischemia-reperfusion and acute myocardial infarction models to study clinical diseases. In the process of preparing the animal model, it is necessary to ligate the left anterior descending coronary artery or inject drugs into various parts of the heart. After the model is prepared, the animals still need to be fed for a period of time. Therefore, improving the survival rate of the animals during the model preparation will greatly increase the success rate of the experiment. [0003] At present, when performing heart operations on small animals, taking the preparation of rat myocardial infarction models as an example, th...
