Abstract
The utility model relates to a leading thread implantation tube lacrimal probe. A probe head, a guide tube, a sleeve barrel and a hollow piston are orderly sheathed on an overlapped leading thread whose folding end forms a thread ring extending out of the probe head to form an associated moving body together with a shaft of the hollow piston. The leading thread of the utility model is arranged in a needle tube; the obstruction position is easy to probe, and the resistance during probing and the damage of the epidermis of a lacrimal canaliculus can be effectively reduced. The leading thread in the needle tube can be taken out and inserted limberly to lead the thread and plant the tube accurately, and the flushing function can be utilized for discern whether the probing is correct or not to prevent the tube from being planted in a false passage. The utility model can be used for planting tubes after the dredging operation of a laser lacrimal passage and can be used reserving the leading thread in the tube when the traumatic lacrimal canaliculus is broken.
Description
This utility model relates to a kind of medical apparatus and instruments, is that a kind of full lacrimal passage lead-in wire is planted the pipe probe specifically.
Normally used band lead-in wire probe and with lumbar puncture needle imitated send the lead-in wire probe, when visiting logical lead-in wire, have the following disadvantages: the one, visit when logical lead-in wire outside pin, increase and visit resistance and the particularly damage of lacrimal ductule epithelium of lacrimal passage epithelium when logical; The 2nd, inconvenience when going out to go between, the inferior nasal meatus hook is arranged, as wanting some training apparatuses, and need its use on top of, even it is outer and realize planting pipe the lead-in wire hook can't to be gone out nasal cavity.
The purpose of this utility model is to provide a kind of can reduce the resistance visited when logical and the damage of lacrimal ductule epithelium effectively, easily visit logical obstructive position, wire can pull and push in needle tubing flexibly and accurately lead-in wire plant pipe, and can check the correct lead-in wire in spy road to plant the pipe lacrimal probe.
The purpose of this utility model is achieved in that a folded mutually wire is overlapped successively and is through at hollow piston axle, in sleeve (the empty tube of syringe), guide wire and the probe; Pig tail folding end becomes a ring to stretch out outside the probe, and the other end is fixed in piston; Guide wire is the body that caliber is narrower than piston hollo, and the axis of the piston is loaded in the sleeve, and guide wire passes the sleeve nipple and inserts in the piston hollo axle, and the probe pintle is placed in outside the sleeve nipple, utilizes the related motion of hollow piston axle and wire, realizes going between and plants pipe.
Feature of the present utility model also be guide wire body one termination be slightly larger than the sleeve nipple expand end or pipe edge, can be embedded in outside the sleeve nipple when the suit guaranteeing.
Feature of the present utility model is that also the axle center of piston can be imitative needle head structure, and the imitative pintle seam of piston pommel can add the dual-purpose joint of dress syringe pipe in the cover one.
The hollow piston axle that the axis of the piston of the present utility model can also be made for overall plastic material.
Said piston axes can also be a puncture needle, to constitute hollow piston axle.
Said wire can be steel wire, nylon yarn.
This utility model can also be made disposable lacrimal probe.
This utility model is when spy is logical, utilize the little ring of probe needle tubing front end wire to guide, finish to visit and lead to, the related motion that utilizes syringe hollow piston axle and wire that continues, bifilar wire is sent into inferior nasal meatus through needle tubing, look test and touch and draw the lead-in wire wire ring blind, be inserted in lead-in wire, thereby realize that lead-in wire plants pipe.Simple in structure, the processing ease of this utility model utilizes the little ring of probe front wire to guide, and the full probing of lacrimal passages of row easily passes obstructive position, be difficult for to form via, wire was twitched in needle tubing when lead-in wire was planted pipe, reduced unnecessary lacrimal passage epithelial damage; Indicate scale on the empty tube of syringe, make and pull and push wire length unanimity, when preventing to go between, lead-in wire wire ring after the bending does not enter needle tubing and damages lacrimal passage, utilize its washing capacity, differentiate to visit logical whether correct, avoid pipe implant via, it not only is suitable for laser lacrimal passage mediation postoperative and plants pipe, also can be used for the lead-in wire of traumatic lacrimal ductule when disconnected and stays pipe.
Fig. 1 is an example structure sketch map of the present utility model;
Fig. 2 is a part confined state sketch map.
Below in conjunction with accompanying drawing this utility model is described in further detail:
Among Fig. 1, be connected with injection form like the sleeve 3 of adorning piston in the probe 1 of the blunt circle of lumbar puncture needle syringe needle and, there is an antrum puncture needle 2 to be hollow piston axle in the piston, one guide wire 4 is arranged in the hollow piston axle 2, the end that expands of guide wire 4 is embedded in engaging in the space 8 of probe pintle 6 and sleeve nipple 7, the wire 9 of appearance poststacks such as a finer wire formation is successively from probe 1, guide wire 4, sleeve 3, hollow piston axle 2 centers are passed and are drawn through hollow piston axle pintle end 10, injection fixed dual-purpose joint 11 1 ends (for imitative nipple structure) snap in hollow piston axle pintle end interface 10, with the wire 9 of fixedly drawing, and wire 9 stumps are inserted the side opening 14 of injection fixed dual-purpose joint 11, avoid wire stump influence operation.Pig tail folding end becomes a ring 16 to stretch out outside the probe, returns the heart piston handle of finding time, and makes silk ring 16 only stay a little ring, fixed piston axle, promptly feasible probing of lacrimal passages.When making irrigation of lacrimal passage, the fixation with steel wire end is inserted in the syringe pipe 15 of injection fixed dual-purpose joint 11, can connect direction shown in the arrow and make irrigation of lacrimal passage.
Among Fig. 2,1 is probe, and 6 is the probe pintle, and 4 is guide wire, and 5 for guide wire expands end, and 3 is sleeve, and 7 is the sleeve nipple, and 2 is the axis of the piston, and 10 is the imitative pintle end of the axis of the piston, and 13 is piston handle, and 9 is wire.
