Abstract
The utility model discloses a kind of distal structure for PTCA sacculus dilating catheters, including inner tube, outer tube, sacculus and multiple developing rings, outer tube to be connected with sacculus rear end；The outer tube is provided with side opening；One end of said inner tube is connected with side opening, and the other end sequentially passes through outer tube, in sacculus, and is stretched out from the front end of sacculus, and tip is round and smooth and have a taper by laser treatment, is fitted close with guiding wire；Between sacculus and side opening, there is outer tube and the pad of inner tube；The developing ring set on inner pipe, and is located in sacculus.The structure has utilization to reduce damage of the conduit to blood vessel, the blood vessel of bending can be more passed through during operation, operation terminates rear foley's tube and smoothly extracted out, mitigate the pain of patient, increase the success rate of operation, coronary intervention is can be widely applied to, can also can be used alone as pre-expansion before storing support or the apparatus expanded afterwards.
Description
Technical field
The utility model is related to a kind of medicine equipment, in particular relate to a kind of PCI percutaneous coronary artery angiography into
The foley's tube of shape art, it is a kind of distal structure for PTCA sacculus dilating catheters.
Background technology
PTCA balloon dilatations are the bases of current all Coronary Artery Disease Intervention Treatment technologies, coronarius narrow again to reduce
Narrow rate, often need to place one piece or more pieces of supports, and prolonged application antiplatelet drug.Foley's tube conveys as intravascular stent
A kind of instrument, played an important role in intravascular stent course of conveying.Under the guiding of guiding wire, blood vessel branch
Frame is transported to lesion locations, until the whole process that sacculus is expanded and extracted out.In surgical procedure, the property of the distal component of conduit
The success or failure of operation can be directly affected.The basic composition of conduit includes：It is handle, distal structure, sacculus, inner tube, distal end outer tube, aobvious
Shadow ring, tip etc..
Because inner tube can become extremely difficult by that can be become bended after the pressure of liquid, in foley's tube extraction,
Meeting injured blood vessel wall, if inner tube material hardness is become big, the compliance of foley's tube will be deteriorated, and foley's tube is difficult to lead to
Cross the blood vessel of complexity；The header terminal design of traditional foley's tube and the goodness of fit of guiding wire are inadequate, or material selection is uncomfortable
Close, influence foley's tube passes through performance.
The content of the invention
The purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of for PTCA sacculus dilating catheters
Distal structure.
The purpose of this utility model is achieved through the following technical solutions：It is a kind of to be used for the remote of PTCA sacculus dilating catheters
End structure, including inner tube, outer tube, sacculus and multiple developing rings, outer tube are connected with sacculus rear end；The outer tube is provided with side opening；Institute
The one end for stating inner tube is connected with side opening, and the other end sequentially passes through outer tube, in sacculus, and is stretched out from the front end of sacculus；Sacculus with
Between side opening, there is outer tube and the pad of inner tube；The developing ring set on inner pipe, and is located in sacculus.
Further, the front end of the sacculus is tightly connected with inner tube.
Further, at pad, outer tube caves inward, and is welded with inner tube 1.
Further, inner tube front end has round and smooth arcuate structure.
Further, at side opening, inner tube is tightly connected with outer tube.
The beneficial effects of the utility model are：
1. increasing spot welding technique at pipe shaft position, make inner tube not flexible, operation terminates rear foley's tube and smoothly extracted out,
Mitigate the pain of patient, increase the success rate of operation；
It is round and smooth and have a taper 2. the tip of inner tube is by laser treatment, it is fitted close with guiding wire, reduces conduit
Damage to blood vessel, the blood vessel of bending can be more passed through during operation；
3. the design of side opening (seal wire fast exchange mouth), shortens venting duration, fast quick-recovery blood circulation state.
Sum it up, the distal structure for being used for PTCA sacculus dilating catheters has simple in construction, easily fabricated, practical side
Just, the advantages of dependable performance, significant effect.
Brief description of the drawings
Fig. 1 is the structural representation for the distal structure that the utility model is used for PTCA sacculus dilating catheters；
Fig. 2 is pad structural representation；
In figure, inner tube 1, outer tube 2, sacculus 3, developing ring 4, side opening 21, pad 22.
Embodiment
As shown in figure 1, a kind of distal structure for PTCA sacculus dilating catheters, including inner tube 1, outer tube 2, the and of sacculus 3
Multiple developing rings 4, outer tube 2 are connected with the rear end of sacculus 3；The outer tube 2 is provided with side opening 21；One end of said inner tube 1 and side opening 21
It is connected, the other end sequentially passes through outer tube 2, in sacculus 3, and is stretched out from the front end of sacculus 3；Between sacculus 3 and side opening 21, have
Outer tube 2 and the pad of inner tube 1 22；The developing ring 4 is enclosed in inner tube 1, and in sacculus 3.
The material of all tubing uses any or its mixing of nylon, nylon elastomer PEBAX, polyethylene, polyester
Thing；Sacculus 3 is blow molded to be formed by balloon forming machine；
The tip of inner tube is round and smooth and have a taper by laser treatment, forms arc, is fitted close, subtracts with guiding wire
Damage of the conduit to blood vessel is lacked, the blood vessel of bending can be more passed through during operation；
Developing ring (3) is to hold machine by developing ring pressure and carry out developing ring 360 ° of rotations to beat and be fixed in inner tube 1,
And surface is smooth, there will not be any damage risk to inner tube (1) or sacculus (3), for being indicated in surgical procedure under X-ray
The position of sacculus (3).
Sacculus (3) is to be welded by laser-beam welding machine with the pattern of circumference soldering with inner tube (1), outer tube 2, welding
Stable and weld force is strong, good airproof performance.
Side opening 21, seal wire fast exchange mouth is also, shortens venting duration, after operation terminates, allow the fast quick-recovery of patient
Blood circulation state.
The position of pad 22, it is to be caved inward by laser-beam welding machine with the bond pattern outer tube waved, with inner tube 1
Welded, welding is stable, by welding, is effectively prevented inner tube 1 by that can be become bended after the pressure of liquid, is performing the operation
Ensure that foley's tube is smoothly extracted out, is mitigated the pain of patient, is increased the success rate of operation after end.
