Abstract

The utility model relates to an improved bushing-type lacrimal passage irrigation probe, which comprises a hard probe composed of a hard probe adapter and a hard probe body and an elastic trocar composed of an elastic trocar adapter and an elastic trocar body, wherein, the hard probe outlet on the hard probe body is arranged on the lower side wall of the hard probe body, and the bottom end of the hard probe body is an enclosed smooth arc end; since the hard probe outlet on the hard probe body is arranged on the lower side wall of the hard probe body and the bottom end of the hard probe body is an enclosed smooth arc end, when the probe is inserted into the lacrimal passage while it rotates, the enclosed smooth arc end of the hard probe body will not cause any injury to the lacrimal passage wall; in addition, the drug liquor jetted from the horizontal hard probe outlet can dilate the lacrimal passage, and therefore is more helpful to insert/draw the utility model into/from the lacrimal passage.

Description

Improved bushing type irrigation of lacrimal passage is visited cleansing pin

Affiliated technical field

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

Background technology

The Chinese utility model patent that the patent No. is 97246465.4, name is called " the bushing type irrigation of lacrimal passage is visited cleansing pin " discloses a kind ofly treats the bushing type irrigation of lacrimal passage that obstructed lacrimal passage uses and visits cleansing pin; the problem of its existence is that rigid spy cleansing pin needle body lower end is a through-type opening; the rigid spy cleansing pin needle body is inserting while rotating in the process of lacrimal passage during use; through-type opening usually can cause damage to the lacrimal passage wall; not only increase patient's misery, and prolonged convalescent period.

Summary of the invention

The purpose of this utility model provides a kind of improved bushing type irrigation of lacrimal passage spy cleansing pin that can not cause additional injuries in the process of inserting lacrimal passage to the lacrimal passage wall.

The purpose of this utility model is to realize like this, a kind of improved bushing type irrigation of lacrimal passage is visited cleansing pin, comprise rigid spy cleansing pin of being made up of the rigid spy cleansing pin joint and the rigid spy cleansing pin needle body and the resilient sleeve bobbin of being made up of the spring-backed quill needle adapter and the resilient sleeve bobbin needle body, the rigid spy cleansing pin outlet on the wherein rigid spy cleansing pin is arranged on the lower end sidewall of the rigid spy cleansing pin needle body; The bottom of the rigid spy cleansing pin needle body is the smooth arc tips of a sealing.

Because the rigid spy cleansing pin outlet on the rigid spy cleansing pin in this utility model is arranged on the lower end sidewall of the rigid spy cleansing pin needle body, and the bottom of the rigid spy cleansing pin needle body is the smooth arc tips of a sealing, so in the time of when it inserts lacrimal passage while rotating among, the smooth arc tips of rigid spy cleansing pin needle body lower end closed can not cause any damage to the lacrimal passage wall; And the medicinal liquid of ejection can also play the effect of expansion lacrimal passage from horizontal rigid spy cleansing pin outlet, can more help plugging in lacrimal passage this utility model like this.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing this utility model is further described, a kind of improved bushing type irrigation of lacrimal passage is visited cleansing pin, comprise rigid spy cleansing pin of being made up of the rigid spy cleansing pin joint 1 and the rigid spy cleansing pin needle body 5 and the resilient sleeve bobbin of being made up of the spring-backed quill needle adapter 2 and the resilient sleeve bobbin needle body 3, the rigid spy cleansing pin outlet 4 on the wherein rigid spy cleansing pin is arranged on the lower end sidewall of the rigid spy cleansing pin needle body 5; The bottom of the rigid spy cleansing pin needle body 5 is the smooth arc tips of a sealing, and in the process that the rigid spy cleansing pin needle body 5 is inserted in the lacrimal passage, the smooth arc tips of the rigid spy cleansing pin needle body 5 sealings just can not cause any extra damage to lacrimal passage like this.

In addition, be beneficial to clean lacrimal passage in order to make to turn forward a little to spray from the medicinal liquids of horizontal rigid spy cleansing pin outlet 4 ejections, the shape of rigid spy cleansing pin outlet 4 can be made water droplet shape, triangle or trapezoidal, as shown in figures 1 and 3, rigid spy cleansing pin outlet 4 is arranged on the lower end sidewall of the rigid spy cleansing pin needle body 5 in its tip portion mode forward; The medicinal liquid of ejection will spray to oblique the place ahead from horizontal rigid spy cleansing pin outlet 4 like this.

During use, as shown in Figure 1, be inserted on the rigid spy cleansing pin joint 1 syringe that cleans medicinal liquid is housed, limit rotation then, marginal not are penetrated, the limit will be nestable together the rigid spy cleansing pin needle body 5 and the rigid spy cleansing pin needle body 3 insertion lacrimal passages among until the obstruction place, and with obstruction place cleaning and dredging; Then, rigid spy cleansing pin is extracted out, the syringe that medicine is housed is inserted on the spring-backed quill needle adapter 2 of the resilient sleeve bobbin of still staying in the lacrimal passage, by still staying the resilient sleeve bobbin needle body 3 in the lacrimal passage to the dispenser of obstruction place.
