Abstract
The utility model provides a nasolacrimal duct bracket which can be left in a human body for re-opening a nasolacrimal duct through a treatment without the need of operation, particularly an appliance for treating nasolacrimal duct obstructive diseases caused by various reasons. The utility model is composed of a duct body (1), an installing leading wire (4) and an adjusting leading wire (7). One end of the duct body (1) is a fish head inclined opening (2). The duct wall with the inclined opening is provided with a circular hole (3). The installing leading wire (4) passes through the leading hole (3), and the duct body (1) is provided with barbs (5). The utility model is characterized in that the duct walls in radial symmetry on the other end of the duct body (1) are provided with a couple of wall holes (6), and the adjusting leading wire (7) passes through the couple of wall holes (6). The utility model has the advantages of easy use, convenient adjustment, high success rate, etc.
Description
Technical field
A kind of lacrimal canal bracket relates to a kind of medical apparatus, particularly a kind of device for the treatment of the obstruction of naso lacrimal duct disease that a variety of causes causes.
Background technology
Obstructed lacrimal passage is the ophthalmology common disease, comprises dacryocystisis and obstruction of lacrimal canaliculus that obstruction of naso lacrimal duct causes.The conventional way of this class disease of treatment is to adopt operative therapy at present.Operative therapy is complicated operation not only, and the patient suffering is many, and the postoperative face leaves cut channel, influences attractive in appearance.(patent No. is my the own Chinese patent of applying on June 19th, 1996 " lacrimal passage the moon is filled in siphunculus and matching used convergent divergent channel again ": ZL96214995.0), providing a kind of can be retained in the human body, make the logical again lacrimal passage of lacrimal passage siphunculus again by non-operative treatment, alleviate the patient treatment misery effectively, reached comparatively satisfied effect.But, after a large amount of clinical practices, find this lacrimal passage again siphunculus mainly exist error correction not strong, promptly install to be difficult to when inaccurate take out once more and install, and the agnail that is arranged at projection on the pipe shaft when installing has bigger resistance, and it is open-minded to cause the leads hole to draw easily, causes to put tube failure.
The utility model content
This utility model provides a kind of and can be retained in the human body, makes the lacrimal canal bracket of ductus nasolacrimalis recanalization by non-operative treatment.It is the improvement invention of Chinese patent " obstructed lacrimal passage is siphunculus and matching used convergent divergent channel again " to my application.This lacrimal canal bracket is made up of pipe shaft, installation lead-in wire and adjustment lead-in wire, and an end of its pipe shaft is a fish head shape inclined-plane opening, offers circular hole on the tube wall of inclined-plane opening, and installing goes between passes from circular hole; On pipe shaft, be provided with agnail; On the radially symmetric tube wall of the other end of pipe shaft, offer a pair of cinclides, adjust lead-in wire and from this a pair of cinclides, pass.Simultaneously, tongue shape hole on the tube wall under the agnail on the pipe shaft.
Because this lacrimal canal bracket offers a pair of cinclides on the radially symmetrical tube wall of the other end of pipe shaft, therefore can from this a pair of cinclides, pass adjusting lead-in wire, when lacrimal canal bracket is installed in position in the nasolacrimal duct when inaccurate, can lacrimal canal bracket be taken out easily refills by adjusting lead-in wire.
Because this lacrimal canal bracket offers the tongue shape hole on the tube wall under the agnail on the pipe shaft, therefore when lacrimal canal bracket is inserted nasolacrimal duct, be arranged on the pipe shaft projection agnail can damping is laggard goes into the tongue shape hole being subjected to, reduce lacrimal canal bracket resistance when inserting nasolacrimal duct effectively, make and lead-in wire is installed is difficult for circular hole is drawn open-minded, and then improved the power that is mounted to of lacrimal canal bracket.
Description of drawings
Below just in conjunction with the accompanying drawings to utility model is described further:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the generalized section of Fig. 1 along the A--A line
Embodiment
As shown in Figure 1 and Figure 2, because this utility model provides a kind of and can be retained in the human body, make the lacrimal canal bracket of ductus nasolacrimalis recanalization by non-operative treatment.Therefore, pipe shaft 1 should be made with the materials such as medical grade silicon rubber that better, do not produce rejection with the tissue compatibility.One end of pipe shaft 1 is a fish head shape inclined-plane opening 2, offers circular hole 3 on the tube wall of inclined-plane opening 2, lead-in wire 4 is installed is passed from circular hole 3; Pipe shaft 1 is provided with guarantees this utility model not eely agnail 5 after being installed on nasolacrimal duct.On the radially symmetric tube wall of the other end of pipe shaft 1, offer a pair of cinclides 6, adjust lead-in wire 7 and from this a pair of cinclides 6, pass.Lead-in wire 4 being installed and being adjusted lead-in wire 7 is medical wire.Lead-in wire 4 is installed is passed circular hole 3 and tie a knot, form knotting 8, one side knotting 8 is the single line part, another side is the two-wire part.Two-wire partly is provided with range mark 9, by range mark 9 is set, can realize the best position of this utility model in nasolacrimal duct more exactly.
In addition, in order to reduce the resistance of lacrimal canal bracket when inserting nasolacrimal duct effectively, make the circular hole of installing on the tube wall that lead-in wire 4 is difficult for wearing out inclined-plane opening 23, this utility model also can offer tongue shape hole 10 on the tube wall under the agnail 5 on the pipe shaft 1, in using process of the present utility model, after being subjected to damping, the agnail 5 that is arranged at the projection on the pipe shaft 1 can enter tongue shape hole 10 like this.
Claims (3)
1, a kind of lacrimal canal bracket, it is made up of pipe shaft (1), installation lead-in wire (4) and adjustment lead-in wire (7), one end of its pipe shaft (1) is a fish head shape inclined-plane opening (2), offers circular hole (3) on the tube wall of inclined-plane opening, lead-in wire (4) is installed is passed from guide hole (3); On pipe shaft (1), be provided with agnail (5), it is characterized in that: on the radially symmetrical tube wall of the other end of pipe shaft (5), offer a pair of cinclides (6), adjust lead-in wire (7) and from this a pair of cinclides (6), pass.
