Abstract

The utility model relates to a cannula type probe for irrigating and probing lacrimal passages, which can once carry out probing, irrigating and dilating lacrimal passages. The utility model is composed of an inner tube probing needle and an elastic cannula needle which is sheathed on the inner tube probing needle. The structure is simple, and the cost is low. The cannula type probe for irrigating and probing lacrimal passages is utilized, which can once carry out the whole treating process of probing, irrigating and dilating lacrimal passages. Therefore, the utility model is easy to operate, avoids or lightens the damage to the lacrimal passages, and enhances the treating effect on the obstruction of the lacrimal passages. If the utility model is made to be a disposable device, the use is more convenient.

Description

The bushing type irrigation of lacrimal passage is visited cleansing pin

This utility model relates to the medical apparatus and instruments that is used for the obstructed lacrimal passage treatment, is that a kind of bushing type irrigation of lacrimal passage is visited cleansing pin.

Obstructed lacrimal passage is an ophthalmology common disease, generally treat at present with polytypic probe groups and flushing needle, flushing and spy are logical will be carried out respectively, particularly expand lacrimal passage, need to enter the purpose that lacrimal passage can reach the expansion lacrimal passage repeatedly with the probe of different model, cause the lacrimal passage wound easily like this, thereby easily cause adhesion and influence therapeutic effect.

In view of the problem of above-mentioned existence, the purpose of this utility model is to design the disposable bushing type irrigation of lacrimal passage that carries out probing of lacrimal passages, irrigation of lacrimal passage and lacrimal passage expansion of a kind of energy and visits cleansing pin.

The purpose of this utility model realizes by following measure: this bushing type irrigation of lacrimal passage is visited cleansing pin and is made of interior pipe spy cleansing pin and resilient sleeve bobbin, and the spring-backed quill needle guard is visited on the cleansing pin at interior pipe; It is longer slightly than resilient sleeve bobbin that interior pipe is visited cleansing pin, and the top that interior pipe is visited cleansing pin is pure circle; In the pipe afterbody of visiting cleansing pin the inner pipe joint that can join with syringe is arranged; The afterbody of resilient sleeve bobbin has the casing joint that can join with syringe; It is that metal inner pipe is visited cleansing pin or interior pipe of hard plastic visited cleansing pin that interior pipe is visited cleansing pin; The resilient sleeve bobbin is the elastic rubber tube trocar or the elastic soft plastic trocar.

Accompanying drawing 1 is the main TV structure sketch map of this utility model most preferred embodiment,

Accompanying drawing 2 is the main TV structure sketch map that the interior pipe in the accompanying drawing 1 is visited cleansing pin,

Accompanying drawing 3 is the main TV structure sketch map of the resilient sleeve bobbin in the accompanying drawing 1,

Coding in the accompanying drawing is respectively: 1 is interior pipe spy cleansing pin, and 2 is the resilient sleeve bobbin, and 3 is inner pipe joint, and 4 are casing joint.

Below in conjunction with most preferred embodiment and accompanying drawing this utility model is further described:

Shown in accompanying drawing 1,2 and 3, this bushing type irrigation of lacrimal passage is visited cleansing pin and is made of interior pipe spy cleansing pin 1 and resilient sleeve bobbin 2, and pipe was visited on the cleansing pin 1 in resilient sleeve bobbin 2 was enclosed within; During use, earlier this bushing type irrigation of lacrimal passage being visited cleansing pin stretches in patient's the lacrimal passage, and in interior pipe spy cleansing pin 1, wash to determine the obstructive position of lacrimal passage, because of resilient sleeve bobbin 2 is visited the obstructive position that cleansing pin 1 has entered lacrimal passage with interior pipe, at this moment pipe is visited cleansing pin 1 and is only kept resilient sleeve bobbin 2 in lacrimal passage in extracting out, in resilient sleeve bobbin 2, carry out irrigation of lacrimal passage then with after proving that the obstruction lacrimal passage is unimpeded, in resilient sleeve bobbin 2, inject 0.2 to 0.5 milliliter of 1% hyaluronic acid sodium gel, make 2 chaps of resilient sleeve bobbin, because of injecting the effect of liquid and resilient sleeve bobbin 2, lacrimal passage is expanded, like this with regard to the disposable probing of lacrimal passages that carries out of energy, irrigation of lacrimal passage and lacrimal passage expansion, thereby avoid or alleviated wound, help the treatment of obstructed lacrimal passage disease, improved therapeutic effect lacrimal passage;

Wherein, it is the longest slightly like spring-backed quill pin 2 that interior pipe is visited cleansing pin 1, and the top that interior pipe is visited cleansing pin 1 is pure circle; In the pipe afterbody of visiting cleansing pin 1 inner pipe joint 3 that can join with syringe is preferably arranged, the afterbody of resilient sleeve bobbin 2 preferably has the casing joint 4 that can join with injection product, like this so that with the syringe fluid injection visit logical, wash and expand; Interior pipe spy cleansing pin 1 can be to manage in metal inner pipe spy cleansing pin or the hard plastic visits cleansing pin; Resilient sleeve bobbin 2 is the elastic rubber tube trocar or the elastic soft plastic trocar.

This utility model is simple in structure, cost is low, utilize this bushing type irrigation of lacrimal passage to visit cleansing pin, to suffering from the obstructed lacrimal passage patient, can disposablely carry out whole therapeutic processes of probing of lacrimal passages, irrigation of lacrimal passage and lacrimal passage expansion, thereby not only operate easily but also avoid or alleviated wound to lacrimal passage, improved therapeutic effect to obstructed lacrimal passage; If be made into disposable using apparatus, use just more convenient.
