Abstract

The utility model provides a balloon lacrimal passage probe, which is applied to ophthalmological probing of a lacrimal passage. A main body structure of the balloon lacrimal passage probe is in the shape of a hollow metal pipe with a closed tail end; the head of the balloon lacrimal passage probe is connected with a rubber balloon; a side wall of which the width is a half of the circumference of the metal pipe and of which the length is one third of the length of the metal pipe is removed from the lower middle part of the metal pipe; and an elastic silica gel sheet is adhered to a gap, so as to recover the integrity of the pipe wall. According to the design, in the probing process of the lacrimal passage, through artificially extruding the rubber balloon on the head of the balloon lacrimal passage probe, gas can enter the metal pipe and the silica gel balloon is inflated and bulged, so the pipe diameter of the lacrimal passage probe is increased, an effect of lacrimal passage expansion is strengthened and the aims of high efficiency and convenience are achieved.

Description

The sacculus lacrimal probe

Affiliated technical field

This utility model is a kind of new instruments of in the ophthalmology probing of lacrimal passage, using.

Background technology

Lacrimal passage is the passing away of tear.Stricture of lacrimal passage is a kind of common ophthalmic diseases, good sending out in middle-aged and elderly people, and like untimely treatment, patient will shed tears throughout one's life.Some patients then develop into chronic dacryocystitis, seriously can cause suppurative keratitis, perforation of cornea even blind, have a strong impact on patients ' life quality.Probing of lacrimal passage is to use probe to visit lacrimal passage logical, the expansion stenosis or occlusion along normal lacrimal passage anatomical structure, thereby reaches the purpose of diagnosis and treatment.Common lacrimal probe is the tinsel with certain degree of hardness and different tube diameters specification.Using the normal generation of the capable probing of lacrimal passages postoperative patient of common probe narrow once more, is present problem demanding prompt solution so seek a kind of mode of efficacious therapy more.

Summary of the invention

In order to improve the therapeutic effect of probing of lacrimal passage, this utility model provides a kind of probing of lacrimal passages equipment of the capsule structure of dribbling.

This utility model solves the technical scheme that its technical problem adopted: agent structure is the tubular metal of hollow, endcapped; Head connects rubber pneumatic bag; The metal tube middle and lower part is removed wide about 1/2nd circumference, is about the long sidewall of 1/3rd metal tubes; Be bonded with elastic silica gel sheet in indentation, there, recover the integrity of tube wall.In the probing of lacrimal passages process, this design can make gas get into metal tube through the rubber pneumatic bag of artificial squeeze bulb, and makes silica gel sheet inflation bulging form sacculus, increases the caliber of lacrimal probe, strengthens the effect of expansion lacrimal passage, realizes the high convenient purpose.

The beneficial effect of this utility model is that this sacculus lacrimal probe has increased the effective diameter of pipe of probe, more effectively reaches the purpose of mechanical expansion lacrimal passage.Simultaneously, the part that caliber increases is the silicone substance of nonmetal character, can not cause the rigid damage of lacrimal passage tube wall, and is safe in utilization convenient.

Description of drawings

Below in conjunction with accompanying drawing and embodiment this utility model is further specified.

Fig. 1 is the outside drawing of this utility model.This utility model comprises: head rubber air bag, tubular metal body, metal tube middle and lower part sidewall silica gel sheet.Part is head rubber air bag and metal tube sidewall silica gel sheet shown in the oblique line.

Fig. 2 is the diagram under this utility model user mode.The rubber pneumatic bag of squeeze bulb behind the probe entering lacrimal passage, gas causes the bulging of silica gel inflated, increases the caliber of lacrimal probe.

The specific embodiment

This utility model agent structure is the tubular metal of hollow, endcapped; Head connects rubber pneumatic bag; The metal tube middle and lower part is removed wide about 1/2nd circumference, is about the long sidewall of 1/3rd metal tubes, is bonded with elastic silica gel sheet in indentation, there, recovers the integrity of tube wall.When probing of lacrimal passages, this probe end is inserted the lacrimal passage lower end gradually through lacrimal point, lacrimal ductule.In this process, can be through the rubber pneumatic bag of squeeze bulb, gas shifts and causes silica gel sheet inflation bulging, has increased the effective volume of treatment.Move up and down probe, make this structure give full play to the purpose of mechanical expansion lacrimal passage, the effectiveness that greatly improves probing of lacrimal passages.

Claims

1. sacculus lacrimal probe; It is characterized in that: agent structure is the tubular metal of hollow, endcapped; Head connects rubber pneumatic bag; The metal tube middle and lower part is removed wide about 1/2nd circumference, is about the long sidewall of 1/3rd metal tubes, is bonded with elastic silica gel sheet in indentation, there, recovers the integrity of tube wall.
