Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the mini coronary artery inflatable balloon occluder comprises an elastic sheath 1, the elastic sheath 1 is 5mm in diameter and 15mm long, the surface of the elastic sheath 1 is provided with cracks, the expansion range of the elastic sheath 1 can be increased by arranging the elastic sheath 1 with the cracks, the myocardium 8 comprises a coronary artery 9, the inner wall of the elastic sheath 1 is fixedly connected with an elastic pad 6, the elastic pad 6 is made of elastic rubber, the mini balloon 2 can be prevented from being infiltrated by the tissue in the body by arranging the elastic pad 6 and the elastic sheath 1 to be matched, the left side of the inner cavity of the elastic sheath 1 is fixedly connected with a sealing block 7, the left side of the sealing block 7 is embedded with a catheter 5, the right side of the catheter 5 penetrates through to the right side of the sealing block 7 and extends to the inner cavity of the elastic sheath 1, the right side of the surface of the catheter 5 is fixedly sleeved with the mini balloon 2, the mini balloon 2 is made, the length of the micro balloon 2 is 8mm, when the micro balloon 2 is in a complete deflation state, the pressure to the coronary artery 9 is almost zero, the micro balloon 2 is provided with a latex film, the micro balloon has the advantages of light weight and high elasticity, the pressure to the coronary artery 9 in a natural state can be greatly reduced, the expansion range is large, the top of the micro balloon 2 is provided with a suture line 3, the suture line 3 is made of polypropylene, the surface of the elastic sheath 1 is provided with two notches 4 matched with the suture line 3, the number of the notches 4 is two, the suture line 3 can conveniently pass through the notches 4, so that subsequent operation is facilitated, one side of the suture line 3, which is far away from the micro balloon 2, extends to the bottom of the coronary artery 9 and penetrates through the cardiac muscle 8, and the micro balloon 2, the suture line 3, the notches 4, the catheter 5, the elastic cushion 6, the sealing block 7, The myocardium 8 and the coronary artery 9 are matched for use, so that the balloon occluder has the advantages of repeatability and safety, and solves the problem that the existing balloon occluder is large in balloon diameter, not suitable for small animals, used in arteries and not capable of being kept in animal bodies for a long time.
