Abstract
The utility model discloses a tear way drainage tube, including body and the drawing head that links to each other with body top, the body is the hollow circular cylinder, and the top drawing head is middle two " C " types pipe arms that are the cross, and two " C " type arm cross departments can thinner cavity tubule of reconnection, and the tubule afterbody is had time and to be knotd by the anchor line (string) for traumatism, the inflammation of tear house steward and lacrimal are blocked. Can pass from the centre of " C " type pipe arm with the pull wire. Compare with current drainage tube, the utility model discloses the drainage tube is can the position in the lacrimal sac more stable, the drainage is more abundant, it is easier relatively to put tub operation, is difficult for coming off after putting the pipe, can improve the success rate of performing the operation.
Description
Technical field
This utility model is the device for ophthalmology lacrimal passage, is applicable to the supporting drainage pipe of ophthalmology lacrimal passage, for various Lacrimal Passage Block and the lacrimal duct injury operation of ophthalmology.
Background technology
In recent years along with progress and the new diseases of science and technology, the less invasive techniques of medical operating obtains good development.Method of putting tube into lacrimal passage from down to up direction have also been obtained development at full speed, easily there are three problems in the drainage tube at present for lacrimal passage supporting drainage: 1, drainage tube implants difficulty pipe in actual operation operation, in implantation process, drainage tube is easy to damage, or the potential safety hazard having fracture residual when taking out; 2, drainage tube can not present tridimensional drainage, the situation that postoperative irrigation is obstructed or logical and not smooth; 3, drainage tube head position in lachrymal sac can not well be fixed, and slide up and down or distortion, the siphonage of lachrymal sac weakens, and occurs that drain is insufficient or can not drain.
Summary of the invention
This utility model lacrimal passage supporting drainage pipe, overcomes the deficiency of existing drainage tube.Make operation relatively be more prone to operation, surgical injury is little, postoperative drainage pipe position stability, not easily slippage, and operative failure can put pipe again.The obstruction of lacrimal ductule, tear house steward, nasolacrimal duct can be solved simultaneously.Drawing head elastic space is large, is easy to implant in art, and in lachrymal sac, present dimensional support, the abundant postoperative tube drawing of drain is safe and efficient.
This utility model is that the technical problem that a kind of lacrimal passage supporting drainage pipe solves crosses the realization of following technical scheme:
Lacrimal passage supporting drainage pipe, the drawing head comprising body and be connected with body, body is hollow cylinder, and drawing head is that two " C " arm in decussation form, two " C " arm decussation places can connect a thinner hollow tubule again, form the outward appearance of a plait increment.
Compared with the existing technology, 1, described drawing head is decussation shape, wear draught line below " C " arm infall, during implantation, under the effect of draught line, drawing head is little spindle, is easier to be entered in lachrymal sac by nasolacrimal duct, and not fragile; When taking out drainage tube under the effect of body external broach amount, drawing head " C " arm can be out of shape and close to each otherly be decreased resistance, avoids damaging, is residually easy to complete taking-up; 2, drawing head solid can strut lachrymal sac after implanting lachrymal sac, and drainage tube position stability, not easily slides up and down and come off; 3, drawing head solid can strut lachrymal sac after implanting lachrymal sac, and the siphonage drain adding lachrymal sac is more abundant, and purulence and sticky discharge not easily remain.4, two " C " arm decussation places can connect a thinner hollow tubule again, and tubule afterbody is free can anchor line (string) knotting, block for tear house steward and dacryocanalicular wound, inflammation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment 1 of this utility model lacrimal passage supporting drainage pipe.
Fig. 2 is the structural representation of the embodiment 2 of this utility model lacrimal passage supporting drainage pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention is further described.
Embodiment 1:
This Novel lacrimal supporting drainage pipe, as shown in Figure 1, comprise body 10 and with the drawing head 20 be connected above body 10, described body 10 and drawing head 20 are made by elasticity medical silica-gel.Described body 10 is hollow circular cylinder, and top drawing head 20 is that two " C " arm 21 in decussation form, and " C " arm 21 indentation, there and below body 10 are connected to form closed irregular annular.
After described lacrimal passage supporting drainage pipe via intranasal application Retrograde lacrimal passage, body is positioned at nasolacrimal duct, and drawing head is positioned at lachrymal sac, can fully drain and can not natural slippage.
Embodiment 2:
As Fig. 2, substantially with embodiment 1, difference is to connect at two " C " arm decussation places a thinner hollow tubule again, and the tail end of tubule (30) has aperture (31).
After described lacrimal passage drainage tubes via intranasal application Retrograde lacrimal passage, body is positioned at nasolacrimal duct, and drawing head is positioned at lachrymal sac, tubule is positioned at tear house steward and lacrimal ductule, narrow or inaccessible tear house steward and lacrimal ductule can be strutted, and can be used in tear house steward and laceration of lacrimal canaliculus operation, play a supporting role.
Claims (4)
1. a lacrimal passage supporting drainage pipe, the drawing head (20) comprising body (10) and be connected with body (10) top, described body (10) is hollow circular cylinder, it is characterized in that: drawing head (20) is that two " C " arm (21) in decussation form, and indentation, there and the body (10) of described " C " arm (21) are connected to form closed irregular annular.
2. lacrimal passage supporting drainage pipe as claimed in claim 1, it is characterized in that: described drainage tube also comprises a hollow tubule (30) thinner than body (10), wherein, the decussation place of two " C " arm connects one end of hollow tubule (30), and the other end of hollow tubule (30) is free end.
3. lacrimal passage supporting drainage pipe as claimed in claim 2, is characterized in that: body (10) and tubule (30) are hollow, and both ends open, is beneficial to drain.
