Abstract
The invention provides a lacrimal passage drainage apparatus consisting of a main tube, a drainage tube and a supporting tube, wherein the main tube and the supporting tube form a straight tube; the side wall of the straight tube is provided with the drainage tube communicated with the main tube; the inner diameter of the main tube is greater than that of the drainage tube; and the inner diameter of the drainage tube is greater than that of the supporting tube. The lacrimal passage drainage apparatus has a tee structure, and the angle between the drainage tube and the supporting tube is designed according to a human body physiological anatomical structure to ensure that the drainage apparatus is closer to a human tissue structure to achieve a comfortable effect; the supporting tube and a nasolacrimal duct form a supporting structure to achieve an effect of supporting stably and ensure that the lacrimal passage drainage apparatus is fundamentally improved from the structural stability. Moreover, by virtue of the contact between a trunk and a lacrimal sac, tears can be drawn conveniently; and the drainage tube of a branch contacts with a nasal cavity to facilitate drainage of tears, and the edges of the trunk and the branch and the connection part between the drainage tube and the supporting tube adopt smooth circular arc transitions to avoid harms to a human body.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of probing of lacrimal passage device.
Background technology
Obstructed lacrimal passage is ophthalmology common disease, frequently-occurring disease, is that one often occurs in lacrimal point, lacrimal ductule, lachrymal sac and nasolacrimal duct intersection and nasolacrimal duct end opening, the disease being cardinal symptom with excessive tear, brings sense of discomfort to patient, affect face.And long-term tear dipping can cause chronic stimulation membranous conjunctivitis, lower eyelid and Face and cheek eczematoid dermatitis.If patient cleans tear for a long time, can lower eyelid ectropion be caused, increase the weight of epiphora symptom further.The Therapeutic Principle of obstructed lacrimal passage controls lachrymal sac inflammation, recovers or sets up lacrimal passage lachrymal sac to nasal cavity drainage channel.If treatment is not thorough, there is the danger of ophthalmic of hiding, outer infection.
Usually by operation, as method treatment obstructed lacrimal passage such as nasal cavity capsula interna anastomosis operation, lacrimal passage intubation operation, lacrimal stent operations.Adopt in operative treatment obstructed lacrimal passage operation process and need to use lacrimal passage drainage tubes, by lacrimal passage drainage tubes, tear is drawn, but existing lacrimal passage drainage tubes majority is straight tube, not easily fixes, poor stability.
Summary of the invention
The object of this invention is to provide that one is easy to fix, the good probing of lacrimal passage device of stability.
For achieving the above object, the technical solution adopted in the present invention is: a kind of probing of lacrimal passage device, be made up of main pipe, drainage tube and stay pipe, main pipe and stay pipe form a straight tube, this straight tube sidewall is provided with the drainage tube be communicated with main pipe, and one end of drainage tube is connected with this straight tube, and the other end of drainage tube is free end, the internal diameter of main pipe is greater than the internal diameter of drainage tube, and the internal diameter of drainage tube is greater than the internal diameter of stay pipe.
The sidewall of the sidewall of described main pipe, the sidewall of drainage tube and stay pipe is all processed with some apertures; The diameter of this aperture is not more than 1mm.
Main pipe mouth of pipe end face, drainage tube mouth of pipe end face and stay pipe mouth of pipe end face are smooth arc surface.
Drainage tube is connected with the smooth arc transition in the junction of main pipe, and drainage tube is connected with the smooth arc transition in the junction of stay pipe.
Probing of lacrimal passage device of the present invention adopts three-port structure, and the angle between drainage tube and stay pipe, according to the design of Human Physiology anatomical structure, makes drainage device more press close to human tissue structure, reaches comfortable effect; The supporting construction that stay pipe and nasolacrimal duct are formed, plays the effect of supporting & stablizing, makes probing of lacrimal passage device have the improvement of essence from the stability of structure.And contacted with lachrymal sac by trunk, conveniently draw tear; The drainage tube of branch contacts with nasal cavity, facilitates the drain of tear, trunk and each edge of branch, and drainage tube and stay pipe connection, all adopts smooth arc transition, avoids the injury to human body.
Accompanying drawing explanation
Fig. 1 is the structural representation of drainage device of the present invention.
In figure: 1. main pipe, 2. drainage tube, 3. stay pipe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, probing of lacrimal passage device of the present invention, be made up of main pipe 1, drainage tube 2 and stay pipe 3, main pipe 1 and stay pipe 3 form a straight tube, this straight tube sidewall is provided with drainage tube 2, and drainage tube 2 is communicated with main pipe 1, and one end of drainage tube 2 is connected with main pipe 1, the other end of drainage tube 2 is free end, forms angle between drainage tube 2 and stay pipe 3; The internal diameter of main pipe 1 is greater than the internal diameter of drainage tube 2, and the internal diameter of drainage tube 2 is more than or equal to the internal diameter of stay pipe 3; The all irregular aperture being distributed with several diameters and being not more than 1mm on the sidewall of main pipe 1, on the sidewall of drainage tube 2 and on the sidewall of stay pipe 3.
The diameter of main pipe 1 is greater than the diameter of drainage tube 2, and the internal diameter of drainage tube 2 is more than or equal to the internal diameter of stay pipe 3, probing of lacrimal passage device of the present invention can be made to meet human body lacrimal passage and physiology of the nose anatomical structure more well, be more conducive to the drain of tear.
Main pipe 1, drainage tube 2 and stay pipe 3 can ensure tear drainage, and on these three pipe sidewalls, the aperture of irregular distribution enables tear moisten lacrimal passage and nasal cavity tissue.Be difficult to the support strength ensureing drainage device when the aperture of aperture is excessive, therefore the diameter setting this aperture is not more than 1mm.
In order to avoid probing of lacrimal passage device causes unnecessary damage or destruction to the lacrimal passage of human body and nasal cavity, each mouth of pipe end face of probing of lacrimal passage device of the present invention all adopts smooth arc surface; And drainage tube 2 is connected with the smooth arc transition in the junction of main pipe 1, drainage tube 2 is connected with the smooth arc transition in the junction of stay pipe 3.
Drainage tube 2 is as supervisor, and stay pipe 3 is as looped pipeline; This supervisor and this looped pipeline are combined into one.
Probing of lacrimal passage device entirety of the present invention is in threeway mouth structure, and main pipe 1 and drainage tube 2 are no longer straight tubes.Drainage tube 2 is for drain tear, and stay pipe 3 plays the effect of supporting & stablizing probing of lacrimal passage device.Between drainage tube 2 and stay pipe 3, the angular dimension of angle designs according to human body lacrimal passage and physiology of the nose anatomical structure, makes drainage device more press close to human tissue structure, reaches comfortable effect.
Drainage device of the present invention adopts medical grade silicon rubber to make; utilize the characteristic of medical grade silicon rubber softness, drainage device, implanting and mean square easy operation when taking out, reduces operating difficulty; avoid unnecessary injury simultaneously, protect lacrimal passage and the nasal cavity tissue of human body better.
During use: the mouth of pipe of main pipe 1 is contacted with lachrymal sac, drainage tube 2 connects nasal cavity, stay pipe 3 and nasolacrimal duct are connected, because drainage device of the present invention adopts stable threeway mouth structure, material is soft medical grade silicon rubber material, therefore can carry out easily flexibly laying and adjusting, be unlikely to cause unnecessary damage to human body.
