Summary of the invention
For overcoming problems of the prior art, this utility model provides a kind of sacculus dilating catheter, sacculus is double-decker, avoid the risk of sacculus explosion over the course for the treatment of, sacculus two ends are stepped, when sacculus intravasation, expansionary force increases progressively step by step, decrease the injury to blood vessel, sacculus outer surface is provided with four solid bars, reduce lifting surface area, increase expansionary force, after sacculus intravasation, bracing frame is positioned at blood vessel mouth and plays a supporting role, to avoid when extracting conduit again out blood vessel dilating again, interior sacculus adopts quality of rubber materials, telescopicing performance is good, outer sacculus and solid bar adopt polyimides material, add the fastness of outer sacculus.This utility model is easy to use, durable in use, effectively improves surgical quality.
For achieving the above object, this utility model is achieved by the following technical solution, and primary structure comprises: interior sacculus, outer sacculus, conduit, bracing frame, handle, liquid injection port, developing ring, liquid outlet, solid bar.Described interior sacculus entirety is cylindrical structure, described outer sacculus is identical with interior balloon features, interior sacculus is wrapped to form an entirety by outer sacculus, in described tube at one end connects, outer sacculus in running through, outer sacculus, from interior, in outer sacculus one end extends to, the outer sacculus other end, support frame as described above is set in the middle part of conduit, described handle is connected with the conduit other end, described liquid injection port is arranged at above handle, conduit, hands handle, liquid injection port is communicated with into a three-port structure, described developing ring is arranged on conduit, described liquid outlet is then a breach of conduit itself, be provided with developing ring, the conduit of liquid outlet is all positioned at sacculus body inside, described solid bar is arranged at sacculus external surface, be connected closely with sacculus body.
Described interior sacculus and outer sacculus two ends stepped, interior sacculus material is quality of rubber materials, and outer sacculus is polyimides material, and the solid bar being positioned at outer balloon surface is identical with outer sacculus material.
Described developing ring has two, lays respectively at the two ends of sacculus body inner conduit.
Support frame as described above is conical structure.
Described sacculus, bracing frame, be socket connection between handle and conduit, bracing frame is identical with balloon diameter with catheter interface place diameter.
The beneficial effects of the utility model: easy to use, simple to operate, durable in use, effectively improve procedure efficiency and to alleviate in operation process surgical apparatus to the injury of human body.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram;
Fig. 2 is sacculus generalized section.
In figure, sacculus, 2-outer sacculus, 3-conduit, 4-bracing frame, 5-handle, 6-liquid injection port, 7-developing ring, 8-liquid outlet, 9-sacculus, 10-solid bar in 1-.
specific embodiments
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, below in conjunction with accompanying drawing, this utility model is elaborated.
A sacculus dilating catheter as shown in Figure 1, primary structure comprises: interior sacculus 1, outer sacculus 2, conduit 3, bracing frame 4, handle 5, liquid injection port 6, developing ring 7, liquid outlet 8, sacculus 9.Described interior sacculus 1 entirety is cylindrical structure, described outer sacculus 2 is identical with interior sacculus 1 shape, two ends are stepped, sacculus 9 intravasation expansionary force increases progressively step by step, decrease the injury to blood vessel, interior sacculus 1 is wrapped to form an overall sacculus 9 by outer sacculus 2, sacculus 1 in described conduit 3 one end connects, outer sacculus 2 also runs through interior sacculus 1, outer sacculus 2, from interior sacculus 1, outer sacculus 2 one end extends to interior sacculus 1, outer sacculus 2 other end, support frame as described above 4 is set in the middle part of conduit 3, bracing frame 4 is positioned at blood vessel mouth and plays a supporting role, to avoid when extracting conduit again out blood vessel dilating again, described handle 5 is connected with conduit 3 other end, described liquid injection port 6 is arranged at above handle 5, conduit 3, handle 5, liquid injection port 6 is communicated with into a three-port structure, described developing ring 7 is arranged on conduit, described liquid outlet 8 is a breach of conduit 3 itself, be provided with developing ring 7, the conduit 3 of liquid outlet 8 is all positioned at sacculus 9 inside.
