Description
Technical field
This utility model relates to a kind of sacculus dilating catheter of exchange guidewire fast, belongs to technical field of medical instruments.
Background technology
At present, while doing Digestive Tract Stenosis expansion or auxiliary expanding treatment under soft scope, sacculus dilating catheter often need to be inserted into diseased region along seal wire, but due to seal wire one end at inside of human body to pathological changes portion position, should not take out, so sacculus dilating catheter can only insert at the seal wire other end, sometimes sacculus dilating catheter is longer, the seal wire other end is difficult to pass from sacculus handle portion thread eye after inserting sacculus, and the longer seal wire of normal employing is performed the operation clinically now, and operation is more loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of sacculus dilating catheter of exchange guidewire is fast provided, it can be from seal wire quick insertion or take out sacculus dilating catheter, thereby easy and simple to handle while making to perform the operation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of sacculus dilating catheter of exchange guidewire fast, it comprises conduit, threeway handle and sacculus, threeway handle has liquid injection port and the thread eye being interconnected, in conduit, be provided with reservoir channel and wire hole, conduit stretches into thread eye, and wire hole and thread eye are connected, one end of sacculus is sealedly connected on the outer wall of conduit front portion, the other end of sacculus is sealedly connected on the outer wall at conduit middle part, and sacculus is connected with liquid injection port by reservoir channel, on the outer wall of described conduit, be provided with developing mark, developing mark is positioned at sacculus, on the outer wall of described conduit, have the quick exchange hole of seal wire, the quick exchange hole of this seal wire is connected with wire hole, and the quick exchange hole of seal wire is positioned at the outside at the other end of sacculus and the place that is tightly connected of conduit.
Further, in order better digestive tract narrow to be developed, described developing mark is provided with two, lays respectively at the two ends of part in supravasal sacculus.
Adopted after technique scheme, this utility model adopts at nearly sacculus end on conduit and opens the quick exchange hole of a seal wire, seal wire penetrates from sacculus dilating catheter head, from the quick exchange hole of seal wire, pass again, without using special lengthening seal wire can complete guide effect, thereby quick insertion or taking-up sacculus dilating catheter, easy and simple to handle while making to perform the operation on seal wire.

Fig. 2 is the structural representation after the balloon expandable of the sacculus dilating catheter of exchange guidewire fast of the present utility model;
Fig. 3 is that the part in Fig. 2 is analysed and observe enlarged diagram.
The specific embodiment
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail below.
As shown in Figures 1 to 3, a kind of sacculus dilating catheter of exchange guidewire fast, it comprises conduit 3, threeway handle 4 and sacculus 1, threeway handle 4 has liquid injection port 4-1 and the thread eye 4-2 being interconnected, in conduit 3, be provided with reservoir channel 3-1 and wire hole 3-2, conduit 3 stretches into thread eye 4-2, and wire hole 3-2 and thread eye 4-2 are connected, one end of sacculus 1 is sealedly connected on the outer wall of conduit 3 front portions, the other end of sacculus 1 is sealedly connected on the outer wall at conduit 3 middle parts, and sacculus 1 is connected with liquid injection port 4-1 by reservoir channel 3-1, on the outer wall of conduit 3, be provided with developing mark 2, developing mark 2 is positioned at sacculus 1, on the outer wall of conduit 3, have the quick exchange hole 3-3 of seal wire, the quick exchange hole 3-3 of this seal wire is connected with wire hole 3-2, and the quick exchange hole 3-3 of seal wire is positioned at the outside at the other end of sacculus 1 and the place that is tightly connected of conduit 3.Pliers path hole of endoscope should be greater than seal wire and sacculus dilating catheter diameter summation.
In order better digestive tract narrow to be developed, as shown in Figure 2, developing mark 2 is provided with two, lays respectively at the two ends of part in the sacculus on conduit 3.
Operation principle of the present utility model is as follows:
This utility model adopts at nearly sacculus end on conduit 3 and opens the quick exchange hole 3-3 of a seal wire, seal wire penetrates from sacculus dilating catheter head, from the quick exchange hole 3-3 of seal wire, pass again, without using special lengthening seal wire can complete guide effect, thereby quick insertion or taking-up sacculus dilating catheter, easy and simple to handle while making to perform the operation on seal wire.
Using method of the present utility model is as follows:
(1), under the supervision of scope or other auxiliary facilities, seal wire is delivered to narrow far-end and kept somewhere.
(2) select suitable sacculus dilating catheter, along seal wire end, insert, from the quick exchange hole of seal wire passes, sacculus dilating catheter is slowly carefully delivered to narrow positions along seal wire, confirmation sacculus 1 is completely adjusted and is stretched out scope, and in suitable position, two developing marks 2 lay respectively at the two ends of narrow positions.
(3) use be with manometric force (forcing) pump by liquid injection port 4-1 to the interior filling liquid of sacculus 1, make sacculus 1 full, when reaching predetermined pressure, be generally sacculus 1 and strut into column completely, stop pressurization, keep 1～3 minute.Notice that moulding pressure can not surpass the withstand voltage of regulation, depending on expansion effect, consider whether will repeatedly expand, repeat expansion and be generally no more than 3 times.
Attention: must not use air or other gaseous matters as the full medium of sacculus 1.
Moulding pressure must not be greater than the withstand voltage of regulation.
If there is sacculus 1, break or occur sacculus 1 pressure drop phenomenon, should stop immediately operation, shrink sacculus 1 and sacculus 1 and scope are done carefully to withdraw from together with as a whole external.Please sacculus 1 is cut off from scope front end, the sacculus 1 again more renewing is implemented operation again.
(4) dilation procedure is drained the liquid in sacculus 1 only after completing, and allows sacculus 1 shrink process, then slowly withdraws from sacculus 1.
Attention: if sacculus 1 is met obstructions when taking out endoscope and answers shut-down operation Bing Jiang endoscope to withdraw from together with sacculus 1.
(5) should to sacculus, carry out waste treatment according to generally acknowledged hospital's criterion.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that this utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
