Abstract
The invention discloses a biological naso-lacrymal duct support device. The biological naso-lacrymal duct support device comprises a saccule booster, wherein a catheter is connected to the saccule booster and comprises a multi-channel structure, a scale mark section, a naso-lacrymal duct support unit and an outlet section which are sequentially arranged from top to bottom; an outlet is formed in the bottom of the outlet section; the multi-channel structure is a hollow casing pipe; and three inlets are formed in the side surface of the multi-channel structure. According to the biological naso-lacrymal duct support device, under direct sight through an ocular endoscope, a sounding and guiding device with a biological support, similar to a lacrimal probe, is implanted into a narrow blocked naso-lacrymal duct to play the roles of dilating, supporting and dredging the lacrimal duct.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of biological lacrimal canal bracket device.
Background technology
Biological support is a kind of to the harmless Wicresoft of human non-toxic, the material of similar angiocarpy bracket.By similar ophthalmic endoscope Lacrimal probe, directly inserted obstruction nasolacrimal duct, dredging lacrimal passage, to reach therapeutic purposes.Existing class Y shape silica gel tube Retrograde art, feature is Wicresoft, and dredging lacrimal passage primary reason passage, reaches therapeutic purposes, existing Lacrimal passage tube, is not finally that to take out be exactly in self falling or residual nasolacrimal duct.The shortcoming of existing biological support is the problem that can not solve stenotic obstruction for a long time, or changes original passage, adhesion again, forms stenotic obstruction, causes palindromia.
Summary of the invention
The object of this invention is to provide a kind of biological lacrimal canal bracket device, solve the problem of easy damaged lacrimal passage organizational structure in the current clinical practice treatment obstructed lacrimal passage lysis existed in prior art.
The technical solution adopted in the present invention is, a kind of biological lacrimal canal bracket device, comprise sacculus booster, sacculus booster is connected with conduit, conduit comprises and is disposed with multi-channel structure, scale mark section, lacrimal canal bracket unit and outlet section from top to bottom, the bottom of outlet section is provided with outlet, and multi-channel structure is the sleeve pipe of hollow, and the side of multi-channel structure is provided with three imports.
Feature of the present invention is also,
Multi-channel structure is cuboid sleeve pipe.
Lacrimal canal bracket unit comprises sacculus, and sacculus arranged outside has network, and sacculus is bonding with critical force with network.
Import is provided with closing valve.
Lacrimal canal bracket unit is Ultimum Ti metal material.
The length of scale mark section is 70mm; The length of lacrimal canal bracket unit is 15mm-30mm; The length of outlet section is 30mm.
The invention has the beneficial effects as follows: this device visits admittance leading-in device by similar lacrimal probe belt transect biological support, within the eye under sight glass direct-view, implant stenotic obstruction nasolacrimal duct, play expansion and support the effect of dredging lacrimal passage.This technology mainly, on existing maturation various lacrimal passage less invasive techniques basis, is improved further and is not being changed original lacrimal passage, i.e. original position lacrimal passage dredging.Purport thinking comes from theory of Chinese medical science, " not bitterly, pain is then obstructed for general rule ".Unobstructed lacrimal passage is without excessive tear, and obstructed lacrimal passage is excessive tear then.
Accompanying drawing explanation
Fig. 1 is the structural representation of the biological lacrimal canal bracket device of the present invention;
Fig. 2 is the enlarged drawing of the lacrimal canal bracket unit of the biological lacrimal canal bracket device of the present invention.
In figure, 1. sacculus booster, 2. conduit, 3. multi-channel structure, 4. lacrimal canal bracket unit, 5. export, 6. import, 7. sacculus, 8. network, 9. scale mark section, 10. valve, 11. outlet sections.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
The invention provides a kind of biological lacrimal canal bracket device, as shown in Figure 1, comprise sacculus booster 1, sacculus booster 1 is connected with conduit 2, conduit 2 comprises and is disposed with multi-channel structure 3 from top to bottom, scale mark section 9, lacrimal canal bracket unit 4 and outlet section 11, the bottom of outlet section 11 is provided with outlet 5, multi-channel structure 3 is the sleeve pipe of hollow, the side of multi-channel structure 3 is provided with three imports 6, each import 6 is provided with closing valve 10, three imports 6 are respectively used to connect camera head, flushing liquor apparatus for placing, cold light source illumination system, whether outlet 5 enters for observing lacrimal passage positional structure and observing flushing liquor, and for flushing liquor is entered lacrimal passage.
Multi-channel structure 3 can be arranged to cuboid sleeve pipe.Lacrimal canal bracket unit 4 comprises sacculus 7, and sacculus 7 arranged outside has network 8, and sacculus 7 is bonding with critical force with network 8.Lacrimal canal bracket unit 4 is Ultimum Ti metal material.The length of scale mark section 9 is 70mm; The length of lacrimal canal bracket unit 4 is 15mm-30mm; The length of outlet section 11 is 30mm.
This device has multiple use, when needs rinse nasolacrimal duct road, opens valve 10, and an import 6 is connected flushing liquor apparatus for placing, and flushing liquor by conduit 2 and outlet 5, enters tear stains road and rinses tear stains road successively.When whether the positional structure and flushing liquor that need observation tear stains road enter, camera head and cold light source illumination system are connected two other import 6 respectively, for observing the positional structure in nasolacrimal duct road, when network 8 is for being elastic tubular structure, shrinking pastes on the minor diameter sacculus 7 do not opened, sacculus 7 is bonding with critical force with network 8, according to scale mark, and the structure in tear stains road on photographic head, lacrimal canal bracket unit 4 is sent into the contraction place in tear stains road by conduit 2, the critical cohesive force of sacculus 7 trigger destruction, network 8 self-expanding, support nasolacrimal duct road, cover lesion, so far network 8 is stayed tear stains road place, the remainder of biological lacrimal canal bracket device is withdrawn from, work process terminates.
It is complete that this device can solve current clinical practice treatment obstructed lacrimal passage disease surgery utensil, and traditional classical utensil is substantially all operate under without direct-view, easy damaged lacrimal passage organizational structure.Application uses for reference current more advanced ophthalmic endoscope technology at direct-view menisectomy, in passing the lacrimal canal bracket of similar intravascular stent is inserted obstruction tear stains.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.
