Problems solved by technology
[0003] When the existing cardiovascular interventional catheter device sends the catheter into the patient's body, the incision is generally at the far end from the heart, and the speed of the catheter is difficult to control when it is inserted, and it is easy to cause damage to the normal blood vessels of the patient. Secondly, the existing Thrombolytic drugs are generally treated separately from stent surgery, which cannot completely solve the patient's symptoms at one time. Often, stent surgery is performed again due to recurrence after injection of thrombolytic drugs. For stent surgery, it is necessary to use a balloon to squeeze the blocked blood vessel and then release the stent. This can easily cause the vessel wall to rupture

Embodiment Construction
[0026] In order to facilitate the understanding of the technical solution of the present invention, the following combination Figure 1-4 For further explanation, the examples do not constitute a limitation to the protection scope of the present invention.
[0027] as attached figure 1 As shown, a cardiovascular intervention catheter device, the catheter is composed of a catheter head 1, a catheter middle part 2, and a control device 3 from left to right;
[0028] The catheter head 1 includes a liquid guide device 11, a puncture needle device 12, and a diverter 13. The liquid guide device 11 includes a liquid hole 111 and an infusion pipeline 112. It is located on the central axis of the catheter head 1 and communicates with the liquid guiding device 11, as attached Figure 4 As shown, there are two puncture needle devices 12, which are respectively located in the middle of the catheter head 1 and are symmetrical up and down with respect to the infusion pipeline 112. The le...

The invention discloses a cardiovascular intervention catheter device. The cardiovascular intervention catheter device comprises a catheter head, a catheter middle part and a control device and is characterized in that the catheter head comprises a liquid guide device, puncture devices and diverters, the catheter middle part is provided with an air bag, a controller controls the puncture devices and the diverters through steel wires, the air bag is inflated through a pushing device arranged in the controller, and the liquid guide device conveys liquid through a liquid pushing device arranged in the controller. The cardiovascular intervention catheter device has the advantages that the cardiovascular intervention catheter is used as the intravascular stent, thrombolysis liquid drugs are released through the liquid guide device, the catheter can easily pass the narrow parts of blood vessels, the puncture devices can help puncture thrombolysis cells to allow the liquid drugs to fast seepto thrombi, the pushing device can precisely control the speed of the catheter entering the body of a patient, and blood in blood vessels can normally flow when the spiral air bag is in an open state.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a cardiovascular intervention catheter device. Background technique [0002] Endovascular interventional diagnosis and treatment technology is widely used in clinical angiography, angioplasty, removal of intravascular thrombus or foreign body, etc. Compared with traditional medical technology, endovascular interventional diagnosis and treatment technology is not only convenient to operate, but also because of the low trauma of interventional treatment, it can reduce the pain of patients, the risk of treatment is small, and the cost of treatment is relatively low. Therefore, this technology is widely used in medicine. field has been widely promoted and used. Intravascular interventional diagnosis and treatment technology uses interventional catheters to reach distant diseased parts in the body, such as coronary arteries and other vascular parts; then inject diagnostic age...
