Abstract
The utility model relates to an artificial probe for implanting the tear tube into the tear channel, comprising an injector connecting part and a combining needle body, which is characterized in that a narrow void is arranged on the hollow tube wall of the needle body along the axial direction of the needle body; a tear point expanding device is arranged at the end of the needle body. An oriented mark indicating the position of the narrow void is made at the connecting part of the injector; the tear point expanding device is smoothly connected by a transitional cone and an end sphere. A wire inlet hole with bigger diameter is arranged in the narrow void at an end of the connecting part of the adjacent injector, a wire outlet hole with bigger diameter is arranged in the narrow void at an end of the adjacent tear point expanding device. The needle body is made of stainless steel harder than medium. The artificial probe for implanting the tear tube into the tear channel of the utility model is suitable for the operation of implanting double-tube artificial tear tube, the line and the needle can be isolated easily, the operation can be simplified, the pain of the patients can be reduced, and the utility model has a simple structure, low cost and easy popularization.
Description
Technical field: this utility model relates to medical science ophthalmic diseases operating theater instruments, relates in particular to the improvement of lacrimal probe structure.
Background technology: lacrimal duct abstruction is common lacrimal passage disease, the existing clinically method of taking two-tube artificial tear duct to implant and undergo surgery and treat, and when carrying out above-mentioned operative treatment, guide line and artificial tear duct need be inserted inferior nasal meatus earlier through lacrimal ductule, manage again to take out from nasal cavity.And original lacrimal probe can only be sent into seal wire inferior nasal meatus, and the nasal cavity that seal wire can not be led, so be difficult to from nasal cavity, draw seal wire, and for the spool integrative-structure the double hose artificial tear duct, because of can not making the line pin after the artificial tear duct implantation puts in place, it separates to extract needle body out, so can not adapt to traction, the implantation of double hose artificial tear duct fully, make troubles to operation technique, increased patient's misery.
Summary of the invention: technical problem to be solved in the utility model is: a kind of two-tube artificial tear duct implant surgery that is applicable to is provided, can easily carry out line, the isolating special-purpose artificial tear duct implantation lacrimal probe of pin.
For this reason, the technical solution of the utility model is: a kind of artificial tear duct is implanted lacrimal probe,, be it is characterized in that in conjunction with forming by syringe connecting portion, needle body: along described needle body axially, on the hollow tube wall of needle body, have a narrow crack together.
On described syringe connecting portion, also indicate the leading mark in indication orientation, narrow crack; Be provided with the punctum dilator that constitutes with terminal smooth connection of hemisphere by transition-cone in the bottom of needle body.
Have the guide line hand-hole of a slightly larger in diameter in the narrow crack of an end of contiguous described syringe connecting portion, the guide line that has a slightly larger in diameter in the narrow crack of an end of contiguous described punctum dilator portals.
The internal diameter of described needle body is 0.33~0.66mm, actual value 0.50mm; External diameter is 0.60~1.20mm, actual value 1.00mm; Length is 40~100mm, actual value 80mm; Described narrow gap length is 0.3mm; Described guide line hand-hole is at the following 2mm of syringe connecting portion, and described guide line portals at the above 1mm of punctum dilator; Described transition-cone height is 3mm, and terminal hemisphere diameter is 0.3mm.
Described needle body is that the hard medical stainless steel material of isogonic is made in using.
Owing to adopted the structure after the above improvement, clinically, allow the doctor that the punctum dilator and the probe of round end are probeed into nasal cavity, and whole process leads the guiding lead and submissively derives automatically from nasal cavity, and cause wound can not for patient's lacrimal passage and nasal cavity interior tissue, when lead lead put in place after, can easily this implantable probe be separated with guide line again, from lacrimal ductule and nasal meatus, extract out again, thereby make things convenient for doctor's operation technique, and alleviate patient's misery and complication; This utility model is simple in structure, and is with low cost, is easy to promote.
Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the positive view of this utility model embodiment.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment: as shown in Figure 1, 2, a kind of artificial tear duct is implanted lacrimal probe,, be it is characterized in that in conjunction with forming by syringe connecting portion 1, needle body 2: along described needle body 2 axially, on the hollow tube wall of needle body 2, have narrow crack 3 one.
On described syringe connecting portion 1, also indicate the leading mark 5 in indication orientation, narrow crack; Be provided with the punctum dilator that constitutes with terminal smooth connection of hemisphere 4-2 by transition-cone 4-1 in the bottom of needle body.
In the narrow crack of an end of contiguous described syringe connecting portion 1, have the guide line hand-hole 3-1 of a slightly larger in diameter, the guide line that in the narrow crack of transition-cone 4-1 one end of contiguous described punctum dilator, has the slightly larger in diameter 3-2 that portals.
The internal diameter of described needle body 2 is 0.50mm, and external diameter is 1.00mm, and length is 80mm; Described narrow crack 3 is wide to be 0.3mm; Described guide line hand-hole 3-1 is at syringe connecting portion 1 following 2mm, and described guide line portals 3-2 at the above 1mm of the transition-cone 4-1 of punctum dilator; Described transition-cone 4-1 highly is 3mm, and terminal hemisphere 4-2 diameter is 0.3mm.
Described needle body 2 is that the hard medical stainless steel material of isogonic is made in using.
Now in conjunction with its operational approach of above description of drawings: implant the lacrimal ductule that lacrimal probe needle body 2 is visited logical patient successively with artificial tear duct of the present utility model earlier, the tear house steward, lachrymal sac, nasolacrimal duct, and enter nasal cavity, needle body 2 is kept somewhere in the lacrimal passage, then the guide line hand-hole 3-1 of the guide line on the artificial tear duct on needle body pushed the inwall of needle body 2 and along skidding off voluntarily through the guide line 3-2 that portals in the narrow crack 3 downwards, make guide line from nasal cavity, derive automatically, then guide line can be pulled out from the narrow crack 3 of probe needle body 2 and make line, pin separates, again needle body 2 and whole probe are extracted out from nasal cavity, utilize the guide line traction artificial tear duct of staying outside the nasal cavity to put in place then, finish the artificial tear duct implant surgery.
