Abstract
The utility model relates to a renal artery ablation radiography/guide catheter with a controllable flexible head. The renal artery ablation radiography/guide catheter with the controllable flexible head comprises a handle (1), a pull rod (2), a catheter body (3) and the controllable flexible end (4), the handle (1) is hollow and tubular, one end of the handle (1) is a joint connected with a contrast agent storage apparatus while the other end is connected with the catheter body (3), the catheter body (3) is a double-cavity pipe, and one cavity of the double-cavity pipe is a contrast agent conveying pipe (5) connected with the contrast agent storage apparatus while the other cavity is a control pipeline (6). The renal artery ablation radiography/guide catheter with the controllable flexible head has advantages that the catheter head is controllable and flexible in structure so that the catheter can adapt to different renal artery opening anatomy structures, the coaxality of the catheter and the renal artery is increased, the operation time is shortened, and the operation safety is improved.
Description
Technical field
This utility model belongs to renal arteriography/guiding catheter technical field, and the renal artery that particularly relates to a kind of head end controllable bending melts radiography/guiding catheter.
Background technology
Percutaneous renal artery sympathetic nerve ablation is mainly undertaken by Femoral Approaches at present, major defect has several as follows: a. conductor housing end structure is fixed, in operation process, cannot successfully manage the anatomical structure of different renal artery openings, increase operating time and the complexity of operation, and reduced operation safety; B. single Femoral Approaches, makes peripheral arterial complication increased risk, punctures at femoral artery, has the probability of the hemorrhage and lower limb arteriovenous fistula of posterior peritoneum, and after pulling out sheath, compressing difficulty is higher, and process is loaded down with trivial details.
Summary of the invention
The renal artery that technical problem to be solved in the utility model is to provide a kind of head end controllable bending melts radiography/guiding catheter, adopts trans-radial/Femoral Approaches to perform the operation, and can successfully manage different renal artery opening anatomical structures; If employing Transradial Artery, can effectively reduce the probability that above vascular complication occurs, increase operation safety.
This utility model solves the technical scheme that its technical problem adopts: provide a kind of renal artery of head end controllable bending to melt radiography/guiding catheter, comprise handle, pull bar, conduit and controllable bending head end, described handle hollow becomes tubulose, described handle one end is that joint connects contrast agent storage apparatus, other end connecting duct, described conduit is double lumen tube, and in described double lumen tube, a chamber is that location of contrast agent delivery pipe is communicated with contrast agent storage apparatus, another chamber is control piper.
The operation approach of described conduit is femoral artery or radial artery.
In described control piper, draught line is set, described draught line is connected with controllable bending head end and pull bar respectively with handle inner via hole, two ends through control piper.
The long 10-20cm of described controllable bending head end.
The long 50-110cm of described conduit.
Described catheter diameter is 5F-7F.
It is writing a Chinese character in simplified form of English French that described F also writes Fr, is the caliber unit of catheter.
Beneficial effect
The utility model has the advantage of, can successfully manage different renal artery opening anatomical structures; If employing Transradial Artery, can effectively reduce the probability that above vascular complication occurs, increase operation safety.

Detailed description of the invention
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for this utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications this utility model after having read the content of this utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figures 1 to 3, a kind of renal artery of head end controllable bending melts radiography/guiding catheter, comprise handle 1, pull bar 2, conduit 3 and controllable bending head end 4, described handle 1 hollow becomes tubulose, described handle 1 one end is that joint connects contrast agent storage apparatus, other end connecting duct 3, described conduit 3 is double lumen tube, and in described double lumen tube, a chamber is that location of contrast agent delivery pipe 5 is communicated with contrast agent storage apparatus, another chamber is control piper 6.
The operation approach of described conduit is femoral artery or radial artery.
The interior draught line 7 that arranges of described control piper 6, described draught line 7 is connected with controllable bending head end 4 and pull bar 2 respectively with handle 1 inner via hole, two ends through control piper 6.
The long 10-20cm of described controllable bending head end 4.
The long 50-110cm of described conduit 3.
Described conduit 3 internal diameters are 5F-7F.
It is writing a Chinese character in simplified form of English French that described F also writes Fr, is the caliber unit of catheter.
In operation, trans-radial/femoral artery puncture, insert 6F radial artery sheath pipe/7F femoral artery sheath pipe, through this sheath pipe, under the guide of superslide seal wire, the renal artery of inserting head end controllable bending melts radiography/guiding catheter in renal artery opening part, according to renal artery opening direction, feature, regulate the direction of conduit controllable bending head end, make the head end height of conduit choose renal artery opening, and keep good alignment, be convenient to the operation technique that next step renal artery melts.
