Abstract

The utility model relates to a through radial artery coronary radiography pipe, by first pipe, second pipe and head pipe three -section connect to form, first pipe is the straight tube, there are two 135 bendings in a second pipe and a pipe connection's one end, it is perpendicular with first pipe with head pipe connection's one end, the head pipe wholly is anti - S -shaped, be equipped with the side opening on the pipe wall, outside first pipe is, in, interior three layer construction, it is interior, the outer nylon material that is, the middle level is the metal mesh grid, the second pipe is made by nylon plastic, the head pipe is made by soft nylon. The utility model discloses moment of torsion conducting power is better in the use, has the good nature controlled, and the pipe gets into coronary more easily, and mild head construction has reduced hematal damage.

Description

Trans-radial coronary arteriography catheter

Technical field

This utility model belongs to technical field of medical instruments, particularly relates to a kind of trans-radial coronary arteriography catheter。

Background technology

The one that coronarography is diagnosis coronary atherosclerotic heart disease (coronary heart disease) is commonly used and effective method, it it is a kind of safer reliable invasive diagnostic techniques, now it is widely used to clinic, it is believed that be diagnosis of coronary heart disease " goldstandard "。Existing trans-radial coronary arteriography catheter in use, is usually present and does not cause conduit not easily to insert coronary artery because torque conduction ability is good, and the head hardness of conduit is higher, it is easy to blood vessel is caused damage。Simultaneously because conduit header terminal design is not good enough, conduit is easily accessible right coronary artery branch, causes serious complication。

Utility model content

Technical problem to be solved in the utility model is to provide a kind of trans-radial coronary arteriography catheter, and torque conduction ability more preferably, has good handling, it is easy to enter coronary artery, reduce the damage to blood vessel。

This utility model solves its technical problem and be employed technical scheme comprise that a kind of trans-radial coronary arteriography catheter of offer, by the first conduit, second conduit and three sections of head conduit connect to form, described first conduit is straight tube, there are two 135 ° bendings in one end that described second conduit and the first conduit connect, vertical with the first conduit with one end that head conduit is connected, described head conduit entirety is reverse-s shape, tube wall is provided with side opening, described first conduit is outward, in, interior three-decker, in, outer layer is nylon material, middle level is metal net, described second conduit is made up of nylon plastic(s), described head conduit is made up of soft nylon。

Described metal net is the braiding of rustless steel 16 ingot mariages。

The single string diameter of described metal net is of a size of 0.04mm, and count is 50DPI。

The diameter of described first conduit, the second conduit and head conduit is 5F。

Beneficial effect

Three sections of conduits that this utility model is gradually lowered by hardness are formed by connecting, first conduit is made up of nylon and metal net, maintaining the pliability adding conduit while conduit has excellent support, torque conduction ability is more preferably in operation to make it, having good handling, conduit is easier to enter coronary artery。Head conduit is made up of soft nylon, structurally flexible, the damage to blood vessel of the conduit head end can be reduced in entering coronary artery process and in angiographic procedure, head conduit adopts " anti-S type " structural design, it is easier to enter right coronary artery, avoid enter into right coronary artery branch, it is to avoid severe complication occurs。Second conduit, as the connection changeover portion of the first conduit and head conduit, is made up of nylon plastic(s), and hardness is moderate。

Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is expanded on further。Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model。In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally。

A kind of trans-radial coronary arteriography catheter as shown in Figure 1, is connected to form by first conduit the 1, second conduit 2 and 3 three sections of head conduit, and diameter is 5F。First conduit 1 is a straight tube。There are two 135 ° bendings in one end that the second conduit 2 is connected with the first conduit 1 so that the second conduit 2 corrects vertical with the first conduit 1 with head conduit 3 is connected one。Head conduit 3 is overall in reverse-s shape, it is easier to entering right coronary artery, tube wall is provided with side opening, it is possible to the appearance of Low perfusion pressure in prevention angiographic procedure, reduces the risk of ventricular fibrillation。

First conduit 1 be outer, in, interior three-decker, inside and outside layer is nylon material, and middle level is metal net。Described metal net is the braiding of rustless steel 16 ingot mariages, single string diameter is of a size of 0.04mm, count is 50DPI (node per inch), maintain the pliability adding conduit while conduit has excellent support, make its in operation torque conduction ability more preferably, conduit be easier to enter coronary artery。

Second conduit 2, as the connection changeover portion of the first conduit 1 and head conduit 3, is made up of nylon plastic(s), and hardness is moderate。

Head conduit 3, as the part entering human coronaries, is made up of soft nylon, structurally flexible so that can reduce the damage to blood vessel of the conduit head end in entering coronary artery process and in angiographic procedure。

In operation process, first carry out radial artery puncturing, insert 6F sheath pipe。Along sheath pipe by 0.035 " seal wire sends into root of ascending aorta。Along 0.035 " seal wire by trans-radial coronary arteriography catheter send into root of ascending aorta。Connect contrast agent bolus equipment, under DSA has an X-rayed, manipulate this angiography catheter and enter left coronary artery, carry out left coronary angiography；Manipulate this angiography catheter again and enter right coronary artery, carry out right coronary artery radiography。
