Abstract
The utility model discloses a lacrimal sac nasal cavity drainage tube comprising a tube body (1), wherein one end of the tube body (1) is provided with a positioning plate (2); a corner is arranged between a first drainage section (1a) and a second drainage section (1b); and the second drainage section (1b) is connected with the positioning plate (2). The drainage tube can conduct effective support and fixing on anastomotie stoma, and press the anastomotie stoma while preventing the anastomotie stoma from adhesion, thus playing the role of bleeding stopping, and has the characteristics of reasonable design, simple structure, fast and convenient installing and dismounting, reliable performance and the like.
Description
Technical field
This utility model relates to a kind of medical apparatus, relates in particular to the drainage tube with lachrymal sac and nasal cavity conducting.
Background technology
Lachrymal gland is positioned at the outer top of eyeball, and it constantly secretes tear, with moistening eyeball surface, makes cornea keep bright.The tear that the normal person secretes out flows into lachrymal sac by lacrimal ductule, flow to nasal cavity by nasolacrimal duct again, does not flow out so do not have tear usually.If long-time trachoma, chronic conjunctivitis or the chronic rhinitis suffered from will be involved the nasolacrimal duct mucosa, cause obstruction of naso lacrimal duct, and then cause chronic dacryocystitis easily.This is because behind the obstruction of naso lacrimal duct, tear accumulates in lachrymal sac moderate stimulation mucosa, makes it the inflammation plumpness, is beneficial to the growth of antibacterial.
Obstruction of naso lacrimal duct, chronic dacryocystitis and mucocele of lacrimal sac etc. adopt relatively difficulty of Drug therapy.The most reliable method is to carry out the dacryocystorhinostomy operative treatment clinically, promptly newly opens a flow-guiding channel between lachrymal sac and nasal cavity.But because of a variety of causes causes operative effect and success rate and be restricted (the domestic successful rate is less than 90%), main cause is that the fixed support of anastomotic stoma has difficulties according to one's analysis, causes the adhesion of postoperative anastomotic stoma.
Chinese patent 200820100498.9 discloses the operation of a kind of dacryocystorhinostomy on August 5th, 2009 and has used drainage tube, and this drainage tube has body, is provided with the button pawl at an end of body, and the other end of body is provided with positioning disk.Above drainage tube is put into the anastomotic stoma of lachrymal sac and nasal cavity, the button pawl is fastened the lachrymal sac wall, and the inwall of positioning disk and nasal cavity is fitted, though can play the effect of drain, the smoothness of drain is not good enough, and installs inconvenient, particularly when taking out, the tip of button pawl might scratch the tissue of anastomotic stoma, therefore necessary SC, and the taking-up operation is comparatively complicated.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of lachrymal sac nasal drain convenient to remove of installing.
The technical solution of the utility model is as follows: a kind of lachrymal sac nasal drain, has body, end at body is provided with positioning disk, its key is: described body is connected to form by first Drainage Section and second Drainage Section, have the turning between first Drainage Section and second Drainage Section, and second Drainage Section links to each other with positioning disk.
Adopt above technical scheme, in the process that the dacryocystorhinostomy operation is carried out, after the anastomotic stoma for the treatment of lachrymal sac and nasal cavity is offered, drainage tube described in the utility model is placed in the anastomotic stoma, the lachrymal sac wall is caught in first Drainage Section, and the inwall of positioning disk and nasal cavity is fitted, first Drainage Section and positioning disk combination play axially and circumferential localized effect, and drainage tube is laid in anastomotic stoma firmly, drainage tube supports anastomotic stoma on the one hand and fixes, and prevents the anastomotic stoma adhesion; The outer wall of body second Drainage Section can also be oppressed anastomotic stoma on the other hand, plays the hemostatic effect.After operation was finished, the centre bore of drainage tube body played interim water conservancy diversion, and the tear of lachrymal sac is caused nasal cavity; Treat the complete molding of anastomotic stoma, clamp positioning disk with tweezers and outwards spur, from anastomotic stoma, withdraw from after making the first Drainage Section plastic deformation, drainage tube can be taken out from nasal cavity, after this carry out the tear drain by anastomotic stoma.This shows, convenient, fast when this utility model is installed and taken out, the tissue injury that can not cause anastomotic stoma, easy and simple to handle, be easy to grasp.
In order to make drain more unimpeded, and strengthen and support localized reliability, rounding off between described first Drainage Section and second Drainage Section, and have 60～90 ° angle between first Drainage Section and second Drainage Section.
As preferably, the length of described first Drainage Section is 3～8mm.
On the tube wall of described first Drainage Section, be distributed with aperture.Except that the mouth of pipe of first Drainage Section as the draining hole, aperture also plays a part to import tear, makes drain more thorough, unobstructed.
As preferably, the aperture of described aperture is 0.2～2mm.
Beneficial effect: this utility model can effectively support and fixes anastomotic stoma, can also oppress anastomotic stoma when preventing the anastomotic stoma adhesion, plays the hemostatic effect, has reasonable in design, simple in structure, dress and gets characteristics such as efficient and convenient, dependable performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, lachrymal sac nasal drain described in the utility model is made of body 1 and positioning disk 2, and body 1 is structure as a whole with positioning disk 2, is made by polyethylene or polypropylene or silicone rubber or polyurethane or other similar macromolecular material.Described body 1 is connected to form by the first Drainage Section 1a and the second Drainage Section 1b, and this body 1 cross section is oval, circular or other shape that is fit to, and the cross section of body 1 centre bore is determined according to actual needs, is preferably ellipse in the present embodiment.The described second Drainage Section 1b is circular arc or linear type, and the second Drainage Section 1b links to each other with positioning disk 2.Described positioning disk 2 adopts the disclosed structure of ZL200820100498.9, does not do at this and gives unnecessary details.
As can be known from Fig. 1, the first Drainage Section 1a is arc or linear type, and length is 3～8mm, is preferably 5mm in the present embodiment.Have the turning between the first Drainage Section 1a and the second Drainage Section 1b, have 60～90 ° angle between the rounding off, and the first Drainage Section 1a between the two and the second Drainage Section 1b.Be distributed with a plurality of aperture 1c on the tube wall of the described first Drainage Section 1a, the aperture of this aperture 1c is 0.2～2mm.The number of described aperture and aperture are determined according to actual needs.
