Description
Technical field
This utility model relates to a kind of measurable sacculus dilating catheter, belongs to technical field of medical instruments.
Background technology
At present, do Digestive Tract Stenosis expansion or auxiliary expanding treatment under soft scope time, due to the amplification to human lesion tissue after scope video picture, cannot well distinguish the size of diseased region, which kind of can not should adopt means to carry out smelting to treat reliable foundation is provided for the later stage, and be now all rely on clinician's experience and the familiarity of used medical apparatus and instruments is judged, can only be maybe could survey the tissue size that just can know after pathological changes in the postoperative taking-up of opponent position after tissue is excised, so be a difficult problem anxious to be resolved now to the big or small preliminary surveying of human lesion tissue under scope.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of measurable sacculus dilating catheter is provided, and it can carry out preliminary surveying to human body alimentary canal narrow positions, thereby tentatively determines narrow section length.
In order to solve the problems of the technologies described above, the first technical scheme of the present utility model is: a kind of measurable sacculus dilating catheter, it comprises conduit, threeway handle and sacculus, threeway handle has the liquid injection port and the thread eye that are interconnected, and 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 multiple developing marks, and the distance of adjacent developing mark all equates, developing mark is all positioned at sacculus.
In order to solve the problems of the technologies described above, the second technical scheme of the present utility model is: a kind of measurable sacculus dilating catheter, it comprises conduit, threeway handle and sacculus, threeway handle has the liquid injection port and the thread eye that are interconnected, in conduit, be provided with reservoir channel and wire hole, described conduit stretches into thread eye, and wire hole and thread eye are connected, on the close outer wall that is connected to conduit front portion in one end of described sacculus, the other end of described sacculus is sealedly connected on the outer wall at conduit middle part, and described sacculus is connected with liquid injection port by reservoir channel, on the outer wall of described conduit, be provided with multiple developing marks, and the distance of adjacent developing mark all equates, developing mark is all positioned at sacculus, on the outer wall of described conduit, be provided with silk-screen graduation mark, and silk-screen graduation mark is positioned at sacculus.
Adopt after technique scheme, sacculus is arrived near human lesion tissue by scope along seal wire, sacculus should stretch out scope front end, and sacculus middle part just can be expanded behind pathological tissues place, forward and backward at balloon expandable, under supervision by scope or other auxiliary facilities, can utilize sacculus internal development labelling or utilize the silk-screen graduation mark of sacculus inside to measure human body narrow positions, tentatively determine narrow section length.

Fig. 2 is the structural representation after the balloon expandable of measurable sacculus dilating catheter of the present utility model;
Fig. 3 is the part enlarged diagram in Fig. 2.
Detailed description of the invention
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.
Embodiment mono-
As shown in Figures 1 to 3, a kind of measurable sacculus dilating catheter, it comprises conduit 1, threeway handle 4 and sacculus 2, threeway handle 4 has the liquid injection port 4-1 and the thread eye 4-2 that are interconnected, in conduit 1, be provided with reservoir channel 17 and wire hole, conduit 1 stretches into thread eye 4-2, and wire hole and thread eye 4-2 are connected, one end of sacculus 2 is sealedly connected on the outer wall of conduit 1 front portion, the other end of sacculus 2 is sealedly connected on the outer wall at conduit 1 middle part, and sacculus 2 is connected with liquid injection port 4-1 by reservoir channel 17, on the outer wall of described conduit 1, be provided with multiple developing marks 3, and the distance of adjacent developing mark 3 all equates, developing mark 3 is all positioned at sacculus 2.
The usage of the present embodiment is as follows:
(1), under the supervision of scope or other auxiliary facilities, seal wire is delivered to narrow far-end indwelling.
(2) select suitable sacculus 2 to expand, insert along seal wire end, slowly carefully deliver to narrow positions, confirmation sacculus 2 is completely adjusted and is stretched out scope, and in suitable position, outside two developing marks 3 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 2, make sacculus 2 full, in the time reaching predetermined pressure, be generally sacculus 2 and strut into column completely, stop pressurization, keep 1～3 minute.Notice that moulding pressure can not exceed the withstand voltage of regulation.Consider whether will repeatedly expand depending on expansion effect, repeat expansion and be generally no more than 3 times.
Attention: a, must not use air or other gaseous matters as the full medium of sacculus 2;
B, moulding pressure must not be greater than the withstand voltage of regulation;
C, break or occur sacculus 2 pressure drop phenomenons if there is sacculus 2, should stop immediately operation, shrink sacculus 2 and sacculus 2 and scope are done carefully to withdraw from together with as a whole external, please sacculus 2 is cut off from scope front end, the sacculus 2 again more renewing is implemented to perform the operation again.
(4) dilation procedure is drained the liquid in sacculus 2 only after completing, and allows sacculus 2 shrink process, then slowly withdraws from sacculus 2.
Attention: if sacculus 2 is met obstructions when taking out endoscope and answers shut-down operation and endoscope is withdrawn from together with sacculus 2.
