Problems solved by technology

During the use of the existing transradial coronary angiography catheter, it is difficult to insert the catheter into the coronary artery due to the poor torque transmission ability, and the head of the catheter is relatively hard, which is easy to cause damage to the blood vessel.
At the same time, due to the poor design of the catheter tip, the catheter is easy to enter the right coronary artery branch, causing serious complications

Embodiment Construction

[0019] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0020] like figure 1 A catheter for transradial coronary angiography is shown, which is composed of a first catheter 1, a second catheter 2 and a head catheter 3 connected in three sections, with a diameter of 5F. The first conduit 1 is a straight pipe. There are two 135° bends at the end of the second conduit 2 connected to the first conduit 1 , so that the end of the second conduit 2 connected to the head conduit 3 is just ...

Abstract

The invention relates to a transradial artery and coronary artery radiography catheter and a use method thereof. The radiography catheter is formed by connecting a first catheter body, a second catheter body and a head catheter body. The first catheter body is of a structure including an outer layer, a middle layer and an inner layer. The inner layer and the outer layer are made of nylon materials, and the middle layer is a metal mesh grid. The second catheter body is made of nylon plastic, and the head catheter body is made of soft nylon. The use method of the transradial artery and coronary artery radiography catheter comprises the following steps that transradial artery puncture is carried out, and a sheathing canal is placed in the transradial artery; a guide wire is put into the root of the aorta ascendens along the sheathing canal; the radiography catheter is put into the root of the aorta ascendens along the guide wire; contrast medium pushing equipment is connected, and the radiography catheter is operated to carry out left and right coronary artery radiography under DSA fluoroscopy. The transradial artery and coronary artery radiography catheter is better in torque conducting capacity in the use process, good controllability is achieved, the catheter can enter the coronary artery more easily, damage to the blood vessel is reduced through the soft head structure, and operation difficulty and operation complications can be reduced through the use method.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a transradial coronary angiography catheter and a use method thereof. Background technique [0002] Coronary angiography is a commonly used and effective method for diagnosing coronary atherosclerotic heart disease (coronary heart disease). It is a relatively safe and reliable invasive diagnostic technique. Heart disease "gold standard". During the use of the existing transradial coronary angiography catheter, it is usually difficult to insert the catheter into the coronary artery due to poor torque transmission capability, and the head of the catheter is relatively hard, which is easy to cause damage to the blood vessel. At the same time, due to the poor design of the catheter tip, the catheter can easily enter the branch of the right coronary artery, causing serious complications. Contents of the invention [0003] The technical problem to be solved by t...
