When lacrimal passage occurs to block, just need to carry out irrigation of lacrimal passage.Patient is in the face of operator, and in the interior portion that adjoins, syringe needle is inserted lacrimal point, deeply about 15 ~ 20mm, then rotates 90.Make needle point towards nasal side, namely the long uranium of syringe needle is parallel to margo palpebrae.Just needle point slowly advances along lacrimal ductule, as non-resistance can advance 5 ~ 6mm.So the flushing needle that current routine clinical uses is the syringe needle of a bending, and the angle between horizontal segment and bending segment is probably 135 °.After determining position, in pipe, inject liquid, firmly evenly, suitably.As resistance is comparatively large during flushing, there is adverse current or flow out from another lacrimal ductule, representing obstructed lacrimal passage.The direction of the different parts block liquid adverse current of lacrimal passage is also different.Be very careful during operation inserting needle, in order to avoid damage mucosa.
If patient is baby, because baby's fitness is low, the insertion work of flushing needle becomes very difficult, and after inserting, because baby struggles, the also mucosa of as easy as rolling off a log damage baby.
Summary of the invention
Easily damage the problem of mucosa when inserting for the current irrigation of lacrimal passage trocar, we disclose a kind of brand-new irrigation of lacrimal passage trocar, comprise flexible irrigation pin, syringe, and connect the needle stand between flushing needle and syringe; Described needle stand forms by the flexible irrigation pin canned paragraph fixed for flexible irrigation pin with for the syringe canned paragraph that syringe is fixing; Described syringe and syringe canned paragraph are detachable connection, and described flexible irrigation pin is made up of inner core and the indwelling casing tube be set in outside inner core.
Here the structure that the silica type material that the indwelling casing tube in flexible irrigation pin mainly refers to meet medical apparatus and instruments standard makes, inner core is through in indwelling casing tube as guiding pin.
Owing to have employed flexible irrigation pin, so and between the nasolacrimal duct of patient particularly baby, there is not the mucosa injury that rigid structure causes, simultaneously on the basis of this structure, the indwelling of short-term can be done, thus realize once inserting, the object of repeatedly rinsing, reduces patient grieved, saves the treatment operating time.
Further, the tip further disclosing described flexible irrigation pin in the present invention is the blunt nosed structure of plane.Thus reduce the damage of inserting and causing.As inserted difficulty, can insert after lacrimal point expansion.
Finally, as the preferred thinking of another one, the outside that we also disclosed described syringe canned paragraph is also provided with position-limited wing.Both facilitated the fixing of needle stand, also played external position-limiting action simultaneously, ensured that the on position of flexible irrigation pin was fixed and short-term indwelling fixing.
