Abstract
The utility model provides a multilayer air bag dilating catheter for the department of hepatobiliary surgery. The multilayer air bag dilating catheter comprises a catheter near end, a long and thin flexible shaft and air bags. The catheter near end is arranged at the head portion of the long and thin flexible shaft, a catheter far end is arranged at the tail end of the long and thin flexible shaft, and the long and thin flexible shaft is covered with the air bags. The air bags comprise the outer-layer air bag, the middle-layer air bag and the inner-layer air bag. The catheter far end is conical. The multilayer air bag dilating catheter has the advantages of being high in insertion strength and rigidity and capable of passing through the narrow area smoothly, and enabling the resistance of passing through the narrow area to be reduced. The change frequency of the catheter is reduced, the pain of repeated intubation injury is relieved for patients, the treatment time is shortened, and the time of irradiation under X rays is shortened for the patients and medical staff.
Description
Technical field
This utility model relates to the field of surgical instruments, relates in particular to a kind of Genneral Surgery multi-layer airbag dilating catheter.
Background technology
In hepatobiliary surgery, balloon dilatation catheter, is mainly used in recovering the expansion at human body Stenosis position, as blood vessel, biliary tract etc., at present, in order to reach the object of expansion, air bag is intrinsic pressure must be higher than two atmospheric pressure, according to the balloon catheter of the length of pathological changes section and stenosis selection different model, conduit is softer, and the power that is slightly hampered can cause expansion difficult intubation, this can cause treatment time long, and patient and medical worker irradiation time under X ray is long.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, and a kind of Genneral Surgery multi-layer airbag dilating catheter is provided.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
A kind of Genneral Surgery multi-layer airbag dilating catheter, comprise catheter proximal end, slender flexible shaft and air bag, slender flexible shaft stem is provided with catheter proximal end, end is provided with distal end of catheter, slender flexible shaft outer wrap has air bag, air bag comprises balloon outer, middle level air bag and inner bladder, and distal end of catheter is tapered.
Further described slender flexible shaft has a guidewire lumen conventionally, length and the inflatable chamber of slender flexible shaft are extended, extend to distal end of catheter from catheter proximal end, and with the internal communication of air bag, inner bladder comprises inner bladder cone, inner bladder cervical region and inner bladder middle part, inner bladder cone outside is coated with middle level air bag cone and balloon outer cone, inner bladder middle part outer side covers has air bag middle part, middle level and balloon outer middle part, air bag is made up of polymeric material, cyst wall is thinner, there is enough pressure, slender flexible shaft is made up of non-toxic polyvinyl chloride material, convenient for cleaning and sterilization.
The utlity model has following beneficial effect:
Genneral Surgery of the present utility model multi-layer airbag dilating catheter, insertion intensity is large, rigidity is strong, can pass through smoothly narrow zone, make the drag reduction by narrow zone, it is few that conduit is changed number of times, alleviates the repeatedly misery of injury of tracheal intubation of patient, shorten treatment time, reduce patient and the irradiation time of medical worker under X ray.
Brief description of the drawings
Fig. 1 is the schematic diagram of Genneral Surgery provided by the utility model multi-layer airbag dilating catheter.
Fig. 2 is the cross section enlarged drawing of Genneral Surgery provided by the utility model multi-layer airbag dilating catheter.
Symbol description:
1: catheter proximal end 2: distal end of catheter 3: slender flexible shaft 4: air bag 5: inner bladder cone 6: inner bladder cervical region 7: inner bladder middle part 8: middle level air bag cone 9: inner bladder middle part 10: balloon outer cone 11: balloon outer middle part
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of embodiment of the present utility model, consult Fig. 1 and Fig. 2, a kind of Genneral Surgery multi-layer airbag dilating catheter, comprise catheter proximal end 1, slender flexible shaft 3 and air bag 4, slender flexible shaft 3 stems are provided with catheter proximal end 1, end is provided with distal end of catheter 2, and slender flexible shaft 3 outer wrap have air bag 4, and air bag 4 comprises balloon outer, middle level air bag and inner bladder.
Further described slender flexible shaft 3 has a guidewire lumen conventionally, length and the inflatable chamber of slender flexible shaft 3 are extended, extend to distal end of catheter 2 from catheter proximal end 1, and with the internal communication of air bag 4, inner bladder comprises inner bladder cone 5, inner bladder cervical region 6 and inner bladder middle part 7, inner bladder cone 5 outsides are coated with middle level air bag cone 8 and balloon outer cone 10, inner bladder middle part 7 outer side covers have air bag middle part 9, middle level and balloon outer middle part 11, air bag 4 is made up of polymeric material, cyst wall is thinner, there is enough pressure, slender flexible shaft 3 is made up of non-toxic polyvinyl chloride material, convenient for cleaning and sterilization.
In hepatobiliary surgery, often need to carry out intubate, use dilating catheter to carry out vasodilation, distal end of catheter 2 is tapered, easily enter narrow zone, air bag 4 is made up of polymeric material, cyst wall is thinner, easier and slender flexible shaft 3 is fitted, air bag 4 wraps up three layers of air bag, there is enough pressure, in the time entering narrower region, three layers of air bag can provide enough air pressure, balloon dilatation catheter can be entered easily, avoid repeatedly changing conduit, alleviate patient's misery, and slender flexible shaft 3 adopts nontoxic pvc material, there is enough intensity and convenient cleaning.
In sum; this utility model is only illustrated with an embodiment of multi-layer airbag dilating catheter Genneral Surgery; but this utility model is not limited to this; it will be appreciated by those skilled in the art that in the case of not departing from the protection domain that claims of the present utility model record and can change arbitrarily and revise.
