Abstract
The invention relates to a renal artery ablation radiography/guide catheter with a controllable bend head end. The renal artery ablation radiography/guide catheter comprises a handle (1), a pull rod (2), a catheter (3) and the controllable bend head end (4), wherein the handle (1) is of a hollow tubular shape; one end of the handle (1) is a connector and is connected with a contrast medium storage instrument; the other end of the handle (1) is connected with the catheter (3); the catheter (3) is a double-cavity pipe; one cavity of the double-cavity pipe is a contrast medium delivery pipe (5) which is communicated with the contrast medium storage instrument; the other cavity of the double-cavity pipe is a control pipeline (6). The renal artery ablation radiography/guide catheter with the controllable bend head end has the advantages that the head end of the catheter is of a controllable bend structure, different renal artery dissection structures are adapted to, the coaxial property of the catheter and the renal artery is increased, the time of operation is shortened, and the operation safety is improved.
Description
Technical field
The invention belongs to renal arteriography/guiding catheter technical field, 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 by this invention 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.
The technical solution adopted for the present invention to solve the technical problems is: 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 invention has the advantages that, 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.
