Background

The important technical means of the modern medical examination of radiography can assist in examining the lesion of a patient more clearly under X-ray, and in the radiography, the radiography catheter is also an important medical instrument which obviously affects the success of the radiography.

At present, the femoral artery is often selected for angiography of heart and cerebral vessels, the existing angiography catheter is also the femoral artery angiography catheter, but according to a large amount of clinical treatment experiences, many diseases enter from the radial artery for angiography, complications of patients are fewer, hemostasis is more convenient and rapid, and then surgery and recovery of the patients can be more facilitated.

However, there is no special radial artery angiography catheter at present, and in actual treatment, even though a patient is subjected to angiography from the radial artery, only the femoral artery angiography catheter can be used, but the femoral artery angiography catheter can not achieve an entrance effect well matched with the radial artery due to the fact that the femoral artery angiography catheter is adaptive to the femoral artery in terms of the pipe shape, the elbow portion and the size, and further the radial artery is often stimulated in actual use, so that spasm and occlusion of a radial artery are caused, and serious influence is caused on angiography.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a radial artery radiography pipe, includes the body, the upper end of body is the corner, and the lower extreme is connected with connecting portion, the corner is one "nearly" style of calligraphy structure, cooperatees with the radial artery, the vertical distance of "nearly" style of calligraphy peak and radian beginning department of corner is 5cm, the "nearly" style of calligraphy peak of corner is 9cm with orificial vertical distance, the end of corner is the mouth of pipe.

Preferably, body outside-in is protective layer, steel wire stratum reticulare and hole layer in proper order, the steel wire stratum reticulare is in situ is provided with four haulage wires along the axial equidistant of body, haulage wire one end is located the free end of corner, and the other end is located the end of body, and is connected with the connecting rod, the connecting rod slides and sets up in seting up the sliding tray on connecting portion, the connecting rod is worn out the sliding tray and is connected with the sliding block.

Preferably, the connection is a luer fitting.

Compared with the prior art, the utility model has the beneficial effects that:

the fixed steel wire rope disclosed by the utility model can achieve the following beneficial effects:

1. the structure of the elbow of the novel radial artery angiography catheter is matched with the radial artery, so that the novel radial artery angiography catheter is a special radiography catheter for the radial artery, and the problem that no special radiography catheter for the radial artery exists at present is solved;

2. this novel radial artery radiography pipe is provided with the connecting portion that can adjust the corner, can convenient and fast more make the radiography pipe get into the patient's blood vessel.
