The specific embodiment
Below in conjunction with accompanying drawing this utility model is done further explain.
Shown in Fig. 1-10; A kind of examination of lacrimal passages of this utility model and the integrated system of treatment; Comprise that conduit visits logical device 1 and visit the tee T 2 that logical device is communicated with conduit, tee T comprises first import 3, second import 4 and exports 5 that conduit is visited the front end insertion lacrimal passage of logical device.The conduit of this utility model is visited logical device and is comprised that further a conduit 6 reaches at the sheathed distensible sacculus 7 of the tube wall external seal of conduit 6 front ends; The rear end of conduit 6 is connected with the outlet of tee T 5; Two separate first tube chamber 8 and second tube chambers 9 along duct direction extension perforation are arranged in the conduit; Sacculus 7 seals on the tube wall of the conduit 6 that surrounds has micropore 10, and micropore 10 is communicated with first tube chamber 8; The front end of first tube chamber is a closed, and the rear end of first tube chamber further is communicated with first import 3 of tee T through the outlet 5 of tee T; The front opening of second tube chamber 9 of conduit 6, the rear end of second tube chamber 9 of conduit 6 further is communicated with second import 4 of tee T through the outlet 5 of tee T 2.
In this example; The end that conduit is visited logical device 1 and tee T 2 can be to be threaded fixing through the helicitic texture (not shown) on the inwall of the outlet of tee T; Also can be the fixed connection of other modes, connect and fix through clamping structure 11 as shown in the drawings.Anyly can realize that conduit is visited logical device to be connected fixed practical implementation means and all can with tee T.
In this example; Conduit 6 is the contractions that slightly slope inwardly of the tube wall of its front end, and its end is the ring cutting conduit of endless belt sword, to guarantee visiting logical device when getting into lacrimal passage; Can expand, cut bone sex organization, fibrous membrane sex organization in the lacrimal passage tissue simultaneously, fibrous scar tissue.
In this example, the end of ring cutting conduit is threaded with tee T or connects and fixes.
In this example; First import of tee T can be connected with pressurization pump-up device or fluid infusion apparatus, pressurizes in tee T from first import of tee T and inflates or inject liquid, and gas or liquid pass through the supravasal micropore of ring cutting; Act on sacculus; Make balloon expandable, thereby will insert the far-end stricture of lacrimal passage expansion at the place, sacculus place of the ring cutting conduit in patient's lacrimal passage, because the complexity obstructed lacrimal passage has many places or ductile pipeline obstruction more; The design that front end has a ring cutting conduit of sacculus meets the treatment demand of complexity obstructed lacrimal passage just; Expansible sacculus can fully be expanded whole section narrow nasolacrimal duct tube chamber simultaneously, tube chamber is produced the elastic dilatation power of a uniform lateral divergence direction, and reach the effect of abundant expansion stricture of lacrimal passage adhesion tube chamber.In this example, length of balloon is 40mm.
In this example, the inside diameter ranges of ring cutting conduit is 0.4～0.6mm, is preferably 0.5mm.
A kind of examination of lacrimal passages of this utility model and the integrated system of treatment are except realizing expanding lacrimal passage; Can also be used other the accessory that is used for examination of lacrimal passages and treatment; These accessories can use separately; Insert the accessory that is used to check and treat obstructed lacrimal passage in first import through tee T or first tube chamber of the second import conductive pipe or second tube chamber; Perhaps these accessories also can be used in case of necessity; Insert the accessory that is used to check and treat obstructed lacrimal passage in first tube chamber of first import through tee T and the second import conductive pipe and second tube chamber simultaneously, make it, and can stretch out from the opening of the leading section of ring cutting conduit deeply to the stricture of lacrimal passage place that the ring cutting catheter proximal end is positioned at.
Such accessory can be the biopsy forceps 12 that is used for the lacrimal passage sampling; Be used for laser therapy at the obstructed lacrimal passage position; Foreign body in the lacrimal passage taken out when promptly being used for the lacrimal passage cell extraction and using the terminal seal wire of biopsy forceps is inserted work cavity from the front end (sound end) of endoscope, after endoscope passes, insert the handle from the front end of handle again, after passing from handle rear end; Tighten the turncap of handle rear end, seal wire and handle are fixed.Biopsy forceps external diameter 1.1mm as shown in Figure 4 in this example, total length is greater than 300mm.
Such accessory can also be to get thing basket 13, gets the thing basket and can get the thing basket for three strands or four strands.During use, the front end of the end of getting the thing basket from handle inserted the handle, tighten the turncap of handle bar rear end then, fixedly get the blue seal wire of thing.With after getting the blue front end of thing and from the service aisle of endoscope, inserting, the pull bar of pulling handle is observed from display, make basket with netting on top entangle in the lacrimal passage ground foreign body or calculus after, endoscope is with handle and gets the thing basket shift out lacrimal passage simultaneously.The total length of getting the thing basket as shown in Figure 5 in this example is greater than 500mm, and diameter is 0.38mm.
Perhaps such accessory can also be the guide wire 14 that is used to dredge, and guide wire can be processed with the polypropylene for medical article material, and this guide wire is inserted from a tube chamber of tee T; Deeply to said ring cutting conduit, and stretch out from the opening of the front end of said ring cutting conduit, treat that guide wire is implanted after; Can extract the ring cutting conduit out, only keep guide wire in human body, and draw it and move up and down; Play the expansion inferior nasal meatus, remove paraplasm granulation tissue in the lacrimal passage, reach the effect of mediation.
The guide wire here can also be used nickel-titanium memory steel wire (not shown); After the one of which end inserts behind the ring cutting conduit and stretches out from the opening of the front end of ring cutting conduit; Can be crooked according to its memory characteristic; To make great efforts returning to original degree of crook, play and remove that the ring cutting conduit is suitable for reading, the effect of the paraplasm granulation tissue of end opening.
Such accessory described in this utility model can also be cytology brush 15 or the little brill 16 of lacrimal passage that is used for the hairbrush appearance of lacrimal passage sampling.In this example, the external diameter of cytology brush is 0.35mm, and length is 265mm.
Certainly, the liquid medicine that the such accessory described in this utility model can also be or be used to treat implements the antiinflammatory processing for the lacrimal passage of expansion.
Above-mentionedly only several kinds of specific embodiments in this utility model are explained; But can not be as the protection domain of this utility model; Every equivalence of having done according to the design spirit in this utility model changes or modifies, and all should think the protection domain that falls into this utility model.
