Abstract
The utility model relates to a be used for constrictive novel safe sacculus expansion pipe of percutaneous expansion heart valve, outer bag waist system that presss from both sides the dress and have the reinforcing net between with the inner bag has circular safety hole, the near-end dress that the outer pipe of sclerosis has the deflection is on the cross, the soft distal end dress is on the connecting pipe of sacculus near-end, the inner tube near-end of wearing in the outer pipe links to each other with the syringe needle of dress on the cross in the cross, the distal end passes the takeover in sacculus and the end cover and links to each other, still be equipped with the two-way piston on the cross and connect the guide tube with connecting and being equipped with the two-way. The utility model discloses the safety vent can not become invalid, has cancelled the blast pipe, and the pipe size is stable, and the operation is safe, accurate, reliable.
Description
This utility model is a kind of new type of safe sacculus dilating catheter that is used for percutaneous expansion valvular stenosis.
Foley's tube in using at present, for example Japan produce according to promise latitude (Inoue) foley's tube etc., have following shortcoming:
1. owing to establish safety vent at the sacculus far-end and easily tear, existing foley's tube is not established safety vent on sacculus, or safety vent is located at the balloon proximal afterbody, and many rolling with pin etc. of safety vent forms.
Because the far-end of sacculus capsula interna is the stress deformation maximum in use, when the capsula interna far-end is torn or bored a hole,, cause safety vent and lost efficacy because of undue extruding near-end retraction stops up safety vent, the liquid in sacculus capsula interna and the external capsule interlayer can't be discharged.
Tear or bore a hole and cause between capsule and to produce interlayer and liquid that filling is entered can't discharge the time when the sacculus capsula interna, foley's tube can't take out from cardiovascular, causes patient's ischemia, anoxia and death.Thereby existing foley's tube uses safety inadequately.
2. the gas in the existing foley's tube is to suck out with syringe by the thin exhaustor that clamps between interior outer catheter.Between interior outer catheter, clamp exhaustor, not only increased the space occupy-place, and increased element, make also very difficult.
The purpose of this utility model is to design a kind of new type of safe sacculus dilating catheter, can effectively overcome the deficiencies in the prior art.
Clamp the external capsule waist that strengthens net between this utility model and capsula interna and be shaped on circular safety vent, the hardening conduit of being outside one's consideration has that the near-end of deflection is contained on the four-way, softish far-end is contained on the connection tube of balloon proximal, be through inner catheter near-end in the outer catheter in four-way be contained in four-way on syringe needle link to each other, far-end passes sacculus and links to each other with adapter in the end cap, two logical pistons also are housed on the four-way and two logical pistons are housed to connect skirt through joint.
This utility model also clamps limited long filament between inner catheter and outer catheter, the far-end of limit for length's line is contained on the connection tube of balloon proximal, near-end is contained on the four-way.
Syringe needle of the present utility model can be contained on the four-way with nut and sealing ring.
Compared with prior art, the utlity model has following advantage:
1. safe in utilization.This utility model built in the external capsule waist, and is prevented safety vent when external capsule is made, rather than rolls with pin etc., and the safety vent initial condition is rounded, the expansion state ovalize.Because balloon waist is thicker, safety vent is difficult for stopping up, and can not lose efficacy, and discharge liquid is rapid, thereby has improved the safe in utilization of foley's tube greatly.
2. cancelled the thin exhaustor between interior outer catheter, simplified processing technology, reduced element and reduced cost, reduced the space occupy-place, reduced suction, discharge opeing body resistance, made the more fast convenience of operation.This utility model can utilize and move the associating sacculus on the gas and shrink and sacculus to be placed on lower to discharge gas, also can be with being contained in logical piston of two on the four-way or two logical piston tube with syringe sucking-off gases.
3. it is thin that this utility model clamps the limit for length who makes with stainless steel filament between interior outer catheter, and occupy-place and percentage elongation are all little, makes that the conduit size is more stable when the lengthening sacculus.
4. two logical pistons are housed on the four-way and two logical pistons are housed and connect skirt through joint, both make things convenient for fluid infusion and pressurization, again pressure limiting valve and manometer can be installed, not only can control the fluid injection volume routinely, may command and measure injection pressure also, operation safe, accurately, reliable.
5. this utility model adopts tube chamber sacculus (promptly do not have waist, far-end and near-end are only arranged) step to finish balloon expandable, is used to expand luminal stenosis, as expansion esophagus, prostate etc.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the local enlarged diagram of population structure.
In accompanying drawing 1, ignored the thickness of each unit, assembly.
Below in conjunction with accompanying drawing this utility model is explained in detail.
And external capsule (3) waist (11) that clamps enhancing net (4) between capsula interna (5) be shaped on circular safety vent, the hardening conduit (1) of being outside one's consideration has the near-end of deflection to be contained on the four-way (13), softish far-end is contained on the connection tube (2) of sacculus (10) near-end, be through inner catheter (9) near-end in the outer catheter (1) in four-way (13) be contained in four-way (13) on syringe needle (15) link to each other, far-end passes sacculus (10) and links to each other with adapter (6) in the end cap (7), two logical pistons (17) also is housed on the four-way (13) and through joint (18) two logical pistons is housed to connect skirt (12).
2. clamp limited long filament (8) between inner catheter (9) and outer catheter (1), the far-end of limit for length's line (8) is contained in that the connection tube (2) of sacculus (10) near-end is gone up, near-end is contained on the four-way (13).
3. syringe needle (15) is contained on the four-way (13) with nut (15) and sealing ring (14).
