Abstract
The utility model provides a lacrimal drainage tube. The lacrimal drainage tube comprises a lacrimal drainage tube body which is 1mm in external diameter and 0.5mm in internal diameter, probes are arranged at two ends of a tube cavity of the lacrimal drainage tube body respectively, a head of each probe is a blunt head and provided with a shaft neck, and a plurality of convex ribs or grooves are formed on or in the outer wall of the lacrimal drainage tube body uniformly. A lacrimal punctum or lacrimal ductule treatment tube with the external diameter of 1-3cm are arranged at the position, 1-3cm distant from two sides, in the middle of the lacrimal drainage tube body. The head of each probe is conical, the top end of each probe is the blunt head, and the probes are made of memory materials. The peripheral wall of a conventional lacrimal drainage tube is improved into a convex rib or groove structure, so that the drainage tube can be better prevented from being adhered to lacrimal mucosae, drainage of tear in lacrimal passages is increased, and postoperative recanalization of the lacrimal passages is benefitted; in addition, the heads of the lacrimal probes are improved to be conical, so that the probes can be more beneficially embedded into lacrimal puncta to operate, and operation of doctors is facilitated.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of lacrimal passage drainage tubes in ophthalmologic operation.
Background technology
Epiphora is a kind of symptom common in ophthalmic diseases, narrow mainly for lacrimal passage (from puncta to nasolacrimal duct), as to block the diseases such as shedding tears, suppurate caused treatment..
Current lacrimal passage drainage tubes, following defect is arranged after clinical use: the drainage tube outer wall is smooth, and easy and lacrimal passage mucosa forms negative pressure, causes and the adhesion of lacrimal passage mucosa, causes tear and liquid medicine to pass through; Moreover the intraluminal end of probe of lacrimal passage drainage tubes is round blunt shape, thicker, the time of passing in operation is longer, easily causes the bad phenomenon such as operation source property puncta damages, tears; Lacrimal passage is placed for a long time after Lacrimal passage tube the damage that causes the puncta place and is caused that lacrimal point siphon power descends to causing and shed tears.
Summary of the invention
A kind of physiological lacrimal passage drainage tubes of normal anatomy that is more suitable for lacrimal passage of this utility model design, be conducive to improve the corrective surgery success rate, removes patient's epiphora discomfort, improves patient's quality of life.
The technical solution of the utility model is for this reason, a kind of lacrimal passage drainage tubes, comprise the probing of lacrimal passage tube body, the external diameter of lacrimal passage drainage tubes is 1mm, internal diameter is 0.5mm, wherein the two ends of lacrimal passage drainage tubes tube chamber are respectively equipped with probe, and end of probe is blunt nosed and is provided with axle journal, it is characterized in that: evenly be provided with a plurality of fins or groove on the outer wall of lacrimal passage drainage tubes; It is that 0.3 ~ 0.6mm lacrimal point or lacrimal ductule are disposed pipe that the middle part of lacrimal passage drainage tubes is provided with external diameter to two ends 1 ~ 3cm.
Improvement to such scheme is: described fin or groove axially arrange along the lacrimal passage drainage tubes outer wall.
Improvement to such scheme is: described fin or groove are spiral-shaped to what arrange along the lacrimal passage drainage tubes outer diameter.
Improvement to such scheme is: the head of probe is conical, and its top is blunt nosed.
Improvement to such scheme is: probe is that memorizing material is made.
?Beneficial effect:
This utility model fin or groove are at the outer wall of road drainage tube body, can stop the adhesion of drainage tube and lacrimal passage mucosa, more be conducive to the drain in lacrimal passage of tear, lacrimal point and lacrimal ductule are disposed the setting of pipe in order to allow medicinal liquid or tear be difficult for stopping up and outflow at the tear stains place at canthus, play better drainage effect.
Spiral-shaped setting is to allow lacrimal passage mucosa and tear flow more equably.
The head of probe is conical, its top be blunt nosed make in operation convenient and swift.
What probe was that memorizing material makes is the bionics to human body, makes again by convenient.
In this utility model, lacrimal passage drainage tubes periphery wall in the past is modified to the spiral grain structure, can better stops the adhesion of drainage tube and lacrimal passage mucosa, increased the drain in lacrimal passage of tear, be conducive to the logical again of postoperative lacrimal passage.In addition, improve the end of probe of lacrimal passage, made it into taper shape, more be conducive to insert the puncta operation, facilitated doctor's operation.
The accompanying drawing explanation
Fig. 1 is the structural representation that this utility model outer wall axially arranges fin or groove.
Fig. 2 is that this utility model outer diameter is to spiral-shaped fin or the structural representation of groove are set.
In figure, 1 is lacrimal passage drainage tubes, the 2nd, and probe, the 3rd, axle journal, the 4th, fin or groove, the 5th, spiral-shaped, the 6th, conical head, the 7th, lacrimal point and lacrimal ductule are disposed pipe.
The specific embodiment
This utility model as shown in Figure 1, 2.
Lacrimal passage drainage tubes 1, the external diameter of lacrimal passage drainage tubes 1 is 1mm, and internal diameter is 0.5mm, and wherein the two ends of lacrimal passage drainage tubes 1 tube chamber are respectively equipped with probe 2, probe 2 heads are blunt nosed and are provided with axle journal 3, evenly be provided with a plurality of fins or groove 4 on the outer wall of lacrimal passage drainage tubes 1; It is that 0.3 ~ 0.6mm lacrimal point or lacrimal ductule are disposed pipe 7 that the middle part of lacrimal passage drainage tubes 1 is provided with external diameter to two ends 1 ~ 3cm.
Fin or groove 4 axially arrange along lacrimal passage drainage tubes 1 outer wall.
Fin or groove 4 are along lacrimal passage drainage tubes 1 outer diameter to spiral-shaped 5 of setting.
The head of probe 2 is conical heads 6, and its top is blunt nosed.
When concrete the making
Lacrimal passage drainage tubes 1, by the better silastic material of histocompatibility, pipe overall diameter 1mm, lumen diameter 0.5mm, pipe outer wall fin or groove 4 used axial or adopts spiral-shaped 5 texture structures, can better stop the adhesion of drainage tube and lacrimal passage mucosa, more be conducive to the drain in lacrimal passage of tear.It is that 0.3 ~ 0.6mm lacrimal point or lacrimal ductule are disposed pipe 7 that the middle part of lacrimal passage drainage tubes 1 is provided with external diameter to two ends 1 ~ 3cm.
Lacrimal point and lacrimal ductule are disposed the setting of pipe 7 in order to allow medicinal liquid or tear be difficult for stopping up and outflow at the tear stains place at canthus, play better drainage effect.
Probe 2: by memorizing material, made, head adopts conical type, more is conducive to insert the puncta operation; Height 7cm, diameter 0.5mm.
The scope of application: be mainly used in lacrimal passage (comprising puncta, lacrimal ductule, tear house steward, nasolacrimal duct) stenosis or occlusion, wound causes a series of lacrimal passage diseases that laceration of lacrimal canaliculus causes; The dacryocystorhinostomy of chronic dacryocystitis etc.
Acute dacryocystitis; Serious systemic disease: coagulation disorders, the bad person's forbidding of cardio-pulmonary function.
