Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an interventional diagnosis and treatment hydrophilic guide wire. Background Art
[0002] In the interventional diagnosis and treatment of cerebrovascular diseases, the loach guidewire with a diameter of 0.035 inches is an essential interventional material. Its main purpose is: when superselecting a certain blood vessel, the loach guidewire arrives in a certain blood vessel cavity in advance, and then leads a catheter of appropriate diameter (4F, 5F, 6F, etc.) in a coaxial manner, and follows closely to reach the destination, such as the ascending aorta, common carotid artery, internal carotid artery, subclavian artery, vertebral artery, etc. During the specific operation, the right hand fixes the guidewire, and the left hand pushes the catheter to reach a specific blood vessel along the guidewire. The guidewire plays a guiding and supporting role in this operation. In order to reduce trauma to the patient, the operator chooses an angiography catheter as thin as possible, and 4F or 5F angiography catheters are most commonly used. In this way, the 4F or 5F angiography catheter can only accommodate a 0.035-inch loach guidewire, and can barely infuse pressurized fluid from the tail end to avoid thrombosis in the catheter. However, the isotonic or hypotonic non-ionic contrast agents used in angiography through angiography catheters have high viscosity and can hardly pass through when the guide wire is in place. Even when pushed by a high-pressure syringe, it is difficult to eject, resulting in the target blood vessel not being filled. Another commonly used action: making a path map, which is also difficult to complete. Currently, the only way to solve these problems is to withdraw the guide wire from the body, leave the catheter in place, and then perform angiography or path map. When superselecting another blood vessel, reintroduce the guide wire. Over the years, people have become accustomed to the above-mentioned operating behaviors, and they have become textbook actions. Little do they know that this action wastes a lot of time and increases the exposure of doctors and examinees.
[0003] In the prior art, a catheter with a thin wall and a large lumen is used, such as a 6F guide catheter, but it has the disadvantages of high cost and poor superselective performance for superselecting a certain blood vessel. It cannot be used routinely. In addition, a thinner loach guidewire is selected, such as a loach guidewire with a diameter of 0.018 inches, but the existing 0.018-inch guidewire on the market is expensive, has low support, and is difficult to pass the angiography catheter coaxially.
