Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a novel anti-offloading coronary stent protection device. Background Art

[0002] At present, coronary stent implantation has become the most effective and commonly used method of interventional treatment for coronary heart disease. It is a treatment technology that uses a catheter to insert a balloon and a coronary stent through a blood vessel into the human body under the monitoring of medical imaging equipment, and then sends it to the narrowed part of the coronary artery. Then the balloon is expanded to expand the narrowed blood vessel, so that the coronary stent is fixed in the vascular lesion for a long time after expansion to ensure the smooth flow of blood. The heart stent, also known as the coronary artery stent, is a commonly used medical device in cardiac interventional surgery. It has the function of dredging arterial blood vessels. After the coronary stent is used for a long time, if the coronary blood vessel where the coronary stent is located has lesions again, the coronary stent may become loose in the blood vessel.

[0003] The utility model with announcement number CN220558146U discloses a novel anti-unloading coronary stent protective device, including a coronary stent body for dredging arterial blood vessels and a balloon inserted in the coronary stent to expand the coronary stent, and the two ends of the coronary stent body are symmetrically provided with a limit cylinder to prevent the coronary limbs and blood vessels from unloading, and the inner diameter of the limit cylinder gradually increases from the side close to the coronary stent body to the side away from the coronary stent body. The utility model can not only increase the fit between the stent and the inner wall of the blood vessel, reduce the gap of the entire coronary stent, prevent the precipitation and adsorption of coagulation substances in the blood on the inner wall of the stent, and reduce the risk of blood vessel embolism, but also increase the flow rate of blood in the stent, and the blood with increased flow rate flushes the inner wall of the stent, preventing the precipitation and adsorption of coagulation substances in the blood on the inner wall of the stent, and can ensure the unblocked stent to a certain extent, thereby further reducing the probability of the coronary stent unloading from the blood vessel.

[0004] When the above technical solution is used,

[0005] (1) It is difficult to ensure that the blood in the tube can circulate quickly, which can easily lead to blood clots and blockage, making the blood flow slower;

[0006] (2) It is difficult to check inside the pipeline, which may lead to inaccurate installation position.

[0007] In view of the above problems, the utility model provides a novel anti-offloading coronary stent protection device. Utility Model Content

[0008] The purpose of the utility model is to provide a novel anti-offloading coronary stent protection device. The utility model can make blood circulation smoother by enlarging the ring openings on both sides, and secondly, the specific position can be carefully checked, thereby solving the problems in the background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new anti-offloading coronary stent protection device, comprising a coronary stent body, one side of the coronary stent body is fixedly connected to an enlarged ring stent, the interior of the coronary stent body is sleeved with a balloon, the interior of the balloon balloon is sleeved with a catheter, one end of the catheter is fixedly connected to a catheter head, the middle of the catheter is fixedly connected to a developing ring, and the other end of the catheter is fixedly connected to a catheter base.

[0010] Furthermore, a first marking ring is fixedly connected to the upper surface of the catheter, and a second marking ring is fixedly connected to one side of the upper surface of the catheter, thereby achieving a marking effect.

[0011] Furthermore, one end of the balloon is fixedly connected to a trachea, and one end of the trachea is fixedly connected to a connecting port, thereby achieving an inflation effect.

[0012] Furthermore, a first connection port is fixedly connected to one side of the front side of the connecting port, and a first connection pipe is sleeved on the front side of the first connection port, thereby achieving a connection effect.

[0013] Furthermore, one end of the first connecting tube is fixedly connected to an inflation valve, and the material of the coronary stent body is medical metal, thereby achieving an inflation effect.

[0014] Furthermore, a deflation switch structure is fixedly connected to the front of the connection port, and the balloon is made of PE, thereby achieving a deflation effect.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model provides a novel anti-offloading coronary stent protection device.

[0017] (1) Through the setting of the coronary stent body and the enlarged ring stent, the effect of rapid circulation is achieved during use. The enlarged rings on both sides can speed up the blood circulation, which can facilitate the passage of clots in the blood and avoid excessive accumulation of clots on the coronary stent, resulting in blood stagnation, thereby improving the effect of patency.

[0018] (2) Through the setting of the catheter and the developing ring, a display effect is achieved during use. The developing ring can be used to check the situation inside the tube, which is convenient for medical staff to make corresponding plans and to observe whether the installation position is in compliance, thereby improving the display effect.
