Abstract
The utility model discloses a coronary artery balloon dilating catheter, which comprises a balloon, a far-end pipe communicated with the balloon, and a front end pipe arranged on the front end of the balloon, wherein the front end pipe is in a cone shape, a front end surface of the front end pipe is an arc surface, a development pipe made of development material is arranged in the balloon, an inner pipe is arranged in the far-end pipe, the front end of the inner pipe is communicated with the development pipe, guide wires are inserted into the inner pipe and the development pipe, and the juncture of the inner pipe and the far-end pipe is sealed with the far-end pipe. The coronary artery balloon dilating catheter disclosed by the utility model has the beneficial effects that (1) the structure is simple; (2) the resistance is greatly reduced in lead-in, and the catheter can smoothly pass through the place where the coronary artery is very narrow; (3) the development pipe made of the development material is arranged in the balloon so as to facilitate the observation of the complete picture of a coronary artery lesion, and the difficulty and the risk of an operation are reduced; and (4) the outer surface of each guide wire is provided with a lubricating layer, so that the sliding performance of the guide wires is improved, and the friction force of the guide wires in the sliding process is reduced.
Description
Technical field
This utility model relates to a kind of coronary artery expansion medical device, particularly a kind of coronary saccule dilating catheter.
Background technology
At present, by coronary saccule dilating catheter stenosis coronarius being carried out dilation therapy is a kind of medical procedure commonly used, but, existing coronary saccule dilating catheter, its front tube is cylindric, thereby in the process that imports, in case enter narrow especially lesion coronarius, because resistance is larger, therefore be not easy by.In addition, the inner tube in the existing coronary saccule dilating catheter, its sacculus only arranges one or two development point usually, thereby can not observe the overall picture at coronary artery pathological changes place, has increased risk and the difficulty of operation.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of simple in structure, be convenient to observe coronary artery pathological changes place overall picture thereby reduce the coronary saccule dilating catheter of operating difficulty and risk.
In order to solve the problems of the technologies described above, coronary saccule dilating catheter of the present utility model, comprise sacculus, the distal tube that is connected with sacculus and be arranged on the front tube of sacculus front end, described front tube is taper, the front end face of described front tube is cambered surface, be provided with the development pipe of being made by developing material in the described sacculus, be provided with inner tube in the described distal tube, the front end of described inner tube is connected with the development pipe, be inserted with seal wire in described inner tube and the development pipe, described inner tube seals mutually with junction and the distal tube of distal tube.
In order to improve the seal wire sliding capability, reduce the frictional force of seal wire in sliding process, coronary saccule dilating catheter of the present utility model, the outer surface of described seal wire is provided with lubricating layer.
The beneficial effect that this utility model is obtained is: (1) is simple in structure; (2) front tube is taper, and the front end face of front tube is cambered surface, thereby when importing, greatly reduces resistance, even if run into narrow especially place coronarius, also can pass through smoothly; (3) be provided with the development pipe of being made by developing material in the sacculus, thereby be convenient to observe the overall picture at coronary artery pathological changes place, reduced difficulty and the risk of operation; (4) outer surface of seal wire is provided with lubricating layer, thereby has improved the seal wire sliding capability, has reduced the frictional force of seal wire in sliding process.

Among the figure: 1, cambered surface, 2, front tube, 3, sacculus, 4, the pipe that develops, 5, inner tube, 6, lubricating layer, 7, seal wire, 8, distal tube.
The specific embodiment
As depicted in figs. 1 and 2, coronary saccule dilating catheter of the present utility model, comprise sacculus 3, the distal tube 8 that is connected with sacculus 3 and be arranged on the front tube 2 of sacculus 3 front ends, described front tube 2 is taper, the front end face of described front tube 2 is cambered surface 1, be provided with the development pipe 4 of being made by developing material in the described sacculus 3, be provided with inner tube 5 in the described distal tube 8, the front end of described inner tube 5 is connected with the pipe 4 that develops, be inserted with seal wire 7 in described inner tube 5 and the pipe 4 that develops, described inner tube 5 seals mutually with junction and the distal tube 8 of distal tube 8; The outer surface of described seal wire 7 is provided with lubricating layer 6.
Coronary saccule dilating catheter of the present utility model, simple in structure, front tube 2 is taper, the front end face of front tube 2 is cambered surface 1, thereby when importing, greatly reduces resistance, even if run into narrow especially place coronarius, also can pass through smoothly.
Coronary saccule dilating catheter of the present utility model is provided with the development pipe 4 of being made by developing material in the sacculus 3, thereby is convenient to observe the overall picture at coronary artery pathological changes place, has reduced difficulty and the risk of operation.
Coronary saccule dilating catheter of the present utility model, the outer surface of seal wire 7 is provided with lubricating layer 6, thereby has improved seal wire 7 sliding capabilities, has reduced the frictional force of seal wire 7 in sliding process.
Claims (2)
