Problems solved by technology

When the perfusion needle is manually inserted into the aorta, the hand may shake, making the insertion position inaccurate or damaging the aortic valve, and the aorta is clamped with an arterial clip to fix the heart on the needle, and the fixation is often unstable, resulting in the heart falling off. situation, or the insertion process requires the cooperation of two persons
Therefore, the heart suspension device in the conventional isolated heart perfusion model is time-consuming and leads to poor cardiac activity; manually inserting the perfusion needle into the aorta, the insertion position is incorrect or the aortic valve is damaged due to hand shaking; or the heart is fixed Unstable and falling off, eventually leading to experiment failure, waste of resources and other shortcomings

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Figure 1 ~ Figure 3 Schematically shows the structure of an isolated perfused heart rapid suspension and fixation device according to an embodiment of the present invention.

[0020] Such as Figure 1 ~ Figure 3 As shown, a rapid suspension and fixation device for an isolated perfused heart includes a bracket 1 , a perfusion needle adjustment device 2 (also referred to as an adjustment device 2 ) and a suspension device 3 .

[0021] figure 1 As shown in , the lower end of the support 1 has a base 11, and what is located on the base 11 is a support rod 12. The support rod 12 is cylindrical (or square column, etc.), and a part of the suspension device 3 is installed and fixed on the upper end of the support 1. The device 2 is installed and fixed between the base 11 and the suspension device 3 .

[0022] Such as figure 1 As ...

Abstract

The invention discloses a rapid hanging and fixing device for an isolated perfused heart. The rapid hanging and fixing device comprises a support, a perfusion needle adjustment device arranged on the support, and a hanging device used for fixing the external isolated heart. The hanging device is arranged on the support. A perfusion needle fixing frame is arranged on the adjustment device. The perfusion needle fixing frame can be controlled by the adjustment device to move so that a perfusion needle arranged on the perfusion needle fixing frame can be accurately inserted in an appropriate position in an aorta of the isolated heart and temporarily fixed, and then the aorta is fixed to the perfusion needle through silk thread ligation. In the whole operation process, it can be effectively avoided that because misoperation is generated by shaking of human hands, aortic valves are damaged and the heart is not firmly fixed or fixed at poor positions, and the rapid hanging and fixing device has the advantages that operation is convenient, the perfusion needle can be conveniently and accurately inserted in the aorta of the heart and then fixed through knotting, and the perfused heart can be transferred as a whole.

Description

technical field [0001] The invention relates to a rapid suspension and fixation device for an isolated perfused heart. Background technique [0002] In teaching and scientific research, the isolated heart perfusion system is usually used for experimental processing of the isolated heart to maintain the activity of the isolated heart. The existing isolated heart perfusion system such as: Langendorff isolated heart perfusion model, which relies on With the advantages of high repeatability and good stability, it has become one of the most widely used experimental models in the field of cardiovascular research. [0003] The heart suspension device in the conventional isolated heart perfusion model has a simple structure, and the perfusion needle needs to be manually inserted into the aorta of the isolated heart, and then the aorta is clamped with an arterial clip to temporarily fix the heart to the perfusion needle, and then ligated with silk thread Secure the aorta to the perf...
