Specifically, comparison needle 4 is provided with scale mark, the blocking position to tear stains of breaking forth can be known more easily according to this scale mark, thus purge operation can be carried out exactly when arriving blocking position in the termination of cleansing pin 5 again.
Preferably, described cleansing pin again 5 has been arranged around scale mark through the position of sleeve pipe stabilizing member 6, to facilitate doctor to know the precession of cleansing pin 5 or the distance of back-out, thus accurately reading the length at obstructed lacrimal passage position again.
Preferably, the front end of described cleansing pin again 5 is screw thread drill bit, is specially blunt taper thread drill bit 501, thus blocking place can more effectively be dredged by cleansing pin 5 again.
Further, described second connector upwardly extends as mushroom-shaped 9, and by the setting of the mushroom head of this extension, doctor can facilitate hand-held when operating re-through device.
Specifically, the rear end of described cleansing pin again 5 arranges handle 11, and the rear end of handle 11 is provided with anti-skidding knob 10, facilitates doctor cleansing pin 5 again carries out precession or screws out operation.
Usually, the end part aligning of the start index labelling on described cleansing pin again 5 and sleeve pipe stabilizing member 6; The precision of the scale on cleansing pin 5 is 0.5mm again, and so, then the length of cleansing pin 5 precession or back-out can read in time, such that it is able to the length of timely judgement place blocking position.
Usually, the front end of described cleansing pin again 5 and described comparison needle 4 flushes, it is simple to operation and comparison; Described cleansing pin again 5 and described comparison needle 4 diameter are 0.5-1mm, can be specifically 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm.
In conjunction with shown in Fig. 1 and Fig. 2, in order to further appreciate that re-through device of the present utility model, under introducing, harpoon shape lacrimal passage detects circulation method more in detail below, and it comprises the following steps:
S1, making U-shaped detector, U-shaped detector is formed by connecting by the rear end of parallel detection pin 2 and scale pin 1;
S2, by the detection pin 2 of U-shaped detector from lacrimal passage lacrimal ductule opening insert lacrimal passage, when lacrimal passage blocking place is arrived in the front end detecting pin 2, read the scale pin 1 scale value at lacrimal passage lacrimal ductule opening part, to obtain the tear lacrimal passage lacrimal ductule opening distance to lacrimal passage blocking place;
S3, according in step S2 obtain lacrimal passage lacrimal ductule opening to the distance of lacrimal passage blocking place, re-through device is oriented distance corresponding with lacrimal passage lacrimal ductule opening to lacrimal passage blocking place;
S4, according in step S3 on re-through device the lacrimal passage lacrimal ductule opening at location place to the distance of lacrimal passage blocking place, re-through device is inserted lacrimal passage from lacrimal passage lacrimal ductule opening, when re-through device arrives lacrimal passage blocking place, rotate the anti-skidding knob 10 of re-through device cleansing pin again, utilize blunt tapered tread drill bit, lacrimal passage blocking place is dredged.
In above-described embodiment, detection pin 2 and scale pin 1 be arranged in parallel, setting by U-shaped detector, detection pin 2 can insert lacrimal passage from lacrimal passage lacrimal ductule opening, when lacrimal passage blocking place is arrived in the front end detecting pin 2, the accurate location that lacrimal passage blocks scale pin 1 can be passed through and read the scale pin 1 scale value at lacrimal passage lacrimal ductule opening part, thus can accurately be known; Then the distance according to the lacrimal passage lacrimal ductule opening obtained in step S2 to lacrimal passage blocking place, re-through device relocates out distance corresponding with lacrimal passage lacrimal ductule opening to lacrimal passage blocking place, according to this distance, re-through device can accurately arrive lacrimal passage blocking place, then lacrimal passage blocking place is dredged exactly; The detection of above-mentioned lacrimal passage circulation method convenient and efficient again is accurate, facilitates doctor accurately to carry out lacrimal passage bypass operation.
Specifically, in step S1, the rear end of U-shaped detector is also associated with handle 3, thus in step s 2, detection pin 2 is inserted lacrimal passage from lacrimal passage lacrimal ductule opening by the handle 3 of the rear end of hand-holdable detector, easy to use; Wherein, the front end detecting pin 2 is round and smooth blunt nosed 201.
Above-mentioned lacrimal passage detects in circulation method again, and along with rotating cleansing pin 5 again, then cleansing pin 5 can steadily translate forward or backward, while translating forward, the blunt tapered tread bit of head end can play the effect of drilling through, and lacrimal passage blocking portion is drilled through, and can read block part length in real time. Obstructed lacrimal passage any part can be carried out Wicresoft and drill through by re-through device of the present utility model, it is possible to avoid visiting by force logical damage lacrimal passage tube wall cause via, and with low cost, operation is simple, it is not necessary to laser and Lachrimal endoscope etc. are assisted.
In sum, in the re-through device for lacrimal passage dredging that this utility model provides, cleansing pin 5 and comparison needle 4 be arranged in parallel again, can the position of distinct blocking according to arranging of comparison needle 4, cleansing pin 5 inserts in tear stains again, it is arranged with sleeve pipe stabilizing member 6 due on cleansing pin 5 again, the outside of sleeve pipe stabilizing member 6 is connected with comparison needle 4 by the first connector 7, cleansing pin 5 can stably enter lacrimal passage again, and nut 8 threaded engagement is on cleansing pin 5 again, the outside of nut 8 is connected with comparison needle 4 by the second connector, so, again cleansing pin 5 can precession or screw out lacrimal passage, thus improve again the precision of cleansing pin 5 operation, when lacrimal passage is dredged, inwall is not easy to damaged, and it is greatly improved lacrimal passage logical success rate again.
Below it is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model know-why; can also making some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
