Description
Technical field
The invention belongs to ophthalmic medical instrument technical field, it is related to a kind of locking type Lacrimal passage irrigator and its installation and removal
Method.
Background technique
Irrigation of lacrimal passage is the diagnosing and treating means of one routine of ophthalmology, suitable for the preoperative of all ophthalmologic operation patients
The diagnosing and treating of disposition and lacrimal passage Disease, irrigation of lacrimal passage need to be entered using dedicated Lacrimal passage irrigator by puncta
Lacrimal is rinsed lacrimal passage using physiological saline or drug.The Lacrimal passage irrigator clinically used at present, irrigation of lacrimal passage
It is common direct insertion interface between needle and syringe, dacryosyrinx and injection can occurs when lacrimal passage blocking or pressure increase
The adverse events that device disengages, clinically occurred adverse events similar for several times, and such event seriously threatens patient and patient
Safety, puncta are located at palpebra inferior endocanthion, easily injure the eyes of patient in case of flushing needle abjection, while being easy to injure
Patient；Flushing liquor spillage certainly will be had after flushing needle abjection, bring the danger of infection.In addition existing flushing needle uses helicitic texture
It is connect with syringe, but flushing needle needs to protrude into use lacrimal passage operation, helicitic texture protruding into and operating
It is easy that flushing needle is made to rotate offset in journey, and using helicitic texture also inconvenient quick-replaceable flushing needle, therefore having must
It improves.
Summary of the invention
