Abstract

The invention provides a puncta expanding hook. According to the technical scheme, the puncta expanding hook comprises a hook body; an extending end of the hook body is used as a hook arm; the surfaces of the hook body and the hook arm are smooth; a handle is arranged at the back of the hook arm; file cut is formed in the surface of the handle; a puncta expanding device with smooth surface is arranged at the back of the handle, and the point end of the puncta expanding device is blunt round. The puncta expanding book has two purposes; the narrow puncta can be expanded, a lacrimal passage pull line in the nasal cavity can be hooked out, and the use is convenient.

Description

Puncta expansion hook

Technical field

The invention belongs to technical field of medical instrument, be that one can expand puncta concretely, can stretch into again the medical device that nasal cavity ticks lacrimal passage pull wire, puncta dilator adds lacrimal passage pull wire hook.

Background technology

The sick equipment of current lacrimal passage is a lot, suffer from obstructed lacrimal passage or narrow and the patient that sheds tears that is that cause is also a lot of clinically, do in the operation technique of lacrimal passage dredging expansion or lacrimal passage built-in pipe to it, first with puncta dilator expansion puncta, then must insert lacrimal passage threading probe, send lacrimal passage pull wire to enter nasal cavity, stretch into nasal cavity with lacrimal passage pull wire hook again and tick lacrimal passage pull wire, draught line is into lacrimal passage pipe again, drives in the wrong direction and draws in lacrimal passage, and art finishes.Such expansion lacrimal point and tick the handy two kinds of equipment of lacrimal passage pull wire, finished product puncta dilator in the past can only be used for expanding puncta, though lacrimal passage pull wire hook in the past can tick lacrimal passage pull wire, but be of rude workmanship, very easily hook broken nasal mucosa, cause epistaxis, structure is extremely unreasonable, during hook lacrimal passage pull wire, pole is not easy, and this just increases operating time and difficulty to medical personnel.Meanwhile, also misery is added to patient.

Summary of the invention

The problems such as solution above-mentioned operation technique trouble is many, and damage is large, and the time is long.

The object of this invention is to provide a kind of structure simple, smooth surface, puncta dilator and lacrimal passage pull wire drag hook are combined together, the shape of hook does again a change, make new puncta expansion hook easy to use, damage nasal mucosa can not be caught on, hook line not only standard is not only steady but also fast, procedure efficiency and quality can be improved, the technical scheme that technical solution problem adopts is: the entirety of puncta expansion hook is based on medical steel, surface light-plated, the one end expanding puncta is coniform, its most advanced and sophisticated blunt circle, puncta can be expanded, not easily cause again puncta damage and lacrimal ductule via damage, its surperficial unusual light.The one end ticking lacrimal passage pull wire is lacrimal passage hook, and hook profile is snag shape, and whole hook is the openings of sizes of large semi-circular, hook, and be 1/3 of whole hook circular diameter, the very blunt circle of bill is smooth, and extends in hook circle.The other end extension of hook increases slightly gradually, smoothly in conical surface is called hook arm, and stretching into nasal cavity, to hook line very quick, at will walks about at nasal cavity, can never cause damage to nasal membrane, more can not cause epistaxis.Connect the mid portion of puncta dilator and lacrimal passage pull wire hook on handle, in cylindric, cut of file shape light-plated is more first made on surface, and the handle that seems after light-plated rubs exquisiteness more, and seemingly frosted sample sense, had both increased the stable degree of hands, and had again flexible sensation.Medical worker is giving in patient's operating process, puncta expansion can be put in place by this puncta expansion hook.Again can accurate quick, catch on nasal cavity lacrimal passage pull wire, damage can not be caused to nasal mucosa, avoid function drawback nasal membrane being had to damage not in place of former puncta dilator and lacrimal passage pull wire hook, alleviate patient's misery, improve procedure efficiency.

The invention has the beneficial effects as follows: structure of the present invention is simple, is medical steel, puncta dilator and lacrimal passage pull wire hook are combined together, two ends are light-plated body, surface unusual light, is conducive to expansion puncta and lacrimal ductule, not easily causes again puncta damage and lacrimal ductule via damage.The other end can catch on lacrimal passage pull wire by accurate quick, can not damage nasal mucosa again, and the handle surfaces of interlude first makes cut of file shape light-plated again, can increase the stable degree of hands, can increase again the flexibility ratio of operation.The damage of puncta and lacrimal ductule leading portion and the damage of nasal membrane can be avoided in a word, alleviate patient's misery, alleviate the work difficulty of medical worker.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, puncta expansion hook of the present invention is further illustrated.

Accompanying drawing is the real sectional view of the present invention.

The hook body of 1. puncta expansion hooks in figure, the 2. hook arm of puncta expansion hook, the 3. handle of puncta expansion hook, 4. the puncta dilator of puncta expansion hook.

Detailed description of the invention

By reference to the accompanying drawings, be described in detail

To accompanying drawing one diameter of phi 0.8mm, be about 10mm smooth surface, pinch the large semi-circular hook of just like steelyard hook sample, the opening of hook is about 2mm, the smooth and hook body (1) that is that stretch in circle of the blunt circle of bill.Hook body extends to hook arm, and increases thick in cone gradually, and the most carefully locate diameter of phi 1mm, thickness diameter of phi 3.8mm, long 40mm, smooth surface is light-plated again, the hook arm (2) in unusual light.Be cylinder afterwards, diameter of phi 3.8mm, long 90mm, cut of file shape light-plated is more first made on surface, in the handle (3) of surperficial fine and smooth cut of file shape, it is finally the pointed cone that is tapered, smooth surface is light-plated again, thick head diameter of phi 3.8mm, thin head apical segment diameter 0.05mm, the puncta dilator (4) of the cone of long 30mm, when medical worker operates to patient, expand puncta with cone, enter after nasal cavity until lacrimal passage pull wire, then go deep into nasal cavity with this hook and tick lacrimal passage pull wire.

Claims

1. puncta expansion hook: the hook body (1) comprising puncta expansion hook, the extendible portion of hook body is hook arm (2), is the handle (3) of puncta expansion hook afterwards, then be puncta dilator (4) after connecting.In the process of lacrimal surgery operation, first puncta is expanded by patent of the present invention, enter after nasal cavity until lacrimal passage pull wire, then stretch into nasal cavity by patent of the present invention and tick lacrimal passage pull wire.
