Abstract
The utility model relates to a lacrimal passage retaining tube for ophthalmic surgery, which comprises a medical resin rubber tube of which the front end is closed and a core rod which is inserted into the medical resin rubber tube, wherein the tube wall of the medical resin rubber tube is provided with a side hole which is communicated with an inner cavity of the medical resin rubber tube; the front end part of the medical resin rubber tube is provided with two side holes which are on the same axial line; the front part and the middle part of the medical resin rubber tube are provided with a plurality of side holes of which the azimuths are mutually staggered. The utility model has the advantages of safe implementation, simplicity and quickness. The utility model can implement the comprehensive irrigation and the drug therapy, and can conveniently take out the retaining tube without infection.
Description
Technical field
This utility model belongs to the auxiliary implement of ophthalmologic operation, specifically a kind of ophthalmologic operation lacrimal passage indwelling tube.
Background technology
At present, can implement probing of lacrimal passages or laser forming art for obstructed lacrimal passage or dacryocystisis, usually adopt silk thread, horse hair traction, epidural catheter is kept somewhere in lacrimal passage, it performs the operation complicated, and in the indwelling process, easily cause the lacrimal passage laceration of canaliculus, cause suffering and wound to the patient, even bring the complication that is difficult to remedy.Chinese patent CN2109832 discloses a kind of irrigation of lacrimal passage conduit, and it is by the silica gel tube of front end sealing and place the nook closing member in the silica gel tube to form, and silica gel tube is provided with the side opening of three flushing usefulness, and 5 millimeters at interval of three side openings insert behind the lacrimal passage proper corresponding with lachrymal sac.Though be beneficial to the flushing to lachrymal sac like this, for whole lacrimal passage, the effect of its flushing and Drug therapy is also disliked shortcoming.In addition, the silica gel tube of this indwelling is difficult to take out from nasal cavity, so be easy to infect when taking out.
Summary of the invention
Problem to be solved in the utility model is: above-mentioned the deficiencies in the prior art are improved, provided a kind of and can implement comprehensively flushing and Drug therapy to lacrimal passage, and can make things convenient for, not have the ophthalmologic operation lacrimal passage indwelling tube that infection ground takes out indwelling tube.
The technical scheme that addresses the above problem is: the ophthalmologic operation that is provided comprises the medical resin sebific duct of a front end sealing and is inserted in the interior core bar of this medical resin sebific duct with the lacrimal passage indwelling tube, the tube wall of medical resin sebific duct is provided with the side opening that communicates with medical resin sebific duct inner chamber, improvements of the present utility model are: be provided with the side opening of two coaxial lines at the leading section of said medical resin sebific duct, be provided with the side opening that a plurality of orientation stagger mutually at the front portion and the middle part of medical resin sebific duct.Above-mentioned core bar plays a part support, is convenient to sebific duct is sent into lacrimal passage; Two side openings of medical resin sebific duct leading section are mainly used in wears draught line (having flushing action concurrently), is convenient to sebific duct is taken out from nasal cavity, avoids the infection to lacrimal passage; Other side opening be distributed in sebific duct around, so can be in all directions lacrimal passage be implemented flushing and Drug therapy.
The front portion of above-mentioned medical resin sebific duct and the side opening at middle part can by helix be distributed in the medical resin sebific duct around.
For the ease of dispenser, the afterbody of above-mentioned medical resin sebific duct can be horn-like.
The utlity model has implement safety, simply, advantage efficiently, adopt this utility model to implement operation and do not destroy the lacrimal passage anatomical structure, can prevent the lacrimal passage adhesion, skin surface does not have cicatrix, and flushing, dispenser are convenient.
Description of drawings
Fig. 1 is the structure chart of an embodiment of this utility model.
The specific embodiment
As shown in Figure 1: medical resin sebific duct 1 adopts silica gel tube, and diameter is 0.9～1mm, and length is 6～8cm, is preferably 6cm; Core bar 2 adopts stainless steel silk, and diameter is 0.4mm, and its tail end 21 is the needle handle shape.The front end sealing of sebific duct 1 is shiny surface; Be provided with the side opening 11 of two coaxial lines apart from the about 2mm of front end place, can wear draught line; All the other side openings 12 by stagger mutually 90 ° or 60 ° in the shape of a spiral line be distributed in sebific duct around; The tail end 13 of sebific duct 1 is horn-like.During use rustless steel core bar 2 is inserted in the sebific duct 1, by the probing of lacrimal passages method sebific duct 1 is sent into desired area (lachrymal sac or nasolacrimal duct or inferior nasal meatus), extract core bar 1 again out, then with the horn mouth injection normal saline of syringe by the sebific duct tail end, be sure of that sebific duct 1 in lacrimal passage, injects medicine at last.Move and protect from infection for fear of the sebific duct of keeping somewhere, the splicing tape 14 in that the tail end of sebific duct 1 is provided with is used for fixing the tail end 13 of sebific duct 1, and seals the tail end horn mouth.
Claims (4)
1, a kind of ophthalmologic operation lacrimal passage indwelling tube, comprise the medical resin sebific duct (1) of a front end sealing and be inserted in the interior core bar (2) of this medical resin sebific duct, the tube wall of medical resin sebific duct is provided with the side opening that communicates with medical resin sebific duct inner chamber, it is characterized in that: be provided with the side opening (11) of two coaxial lines at the leading section of said medical resin sebific duct, be provided with the side opening (12) that staggers mutually in a plurality of orientation at the front portion and the middle part of medical resin sebific duct.
