Description

Nasal cavity lachrymal sac positioner

Technical field

This utility model relates to a kind of positioner that is used for the treatment of dacryocystisis, provides brightness to come the assist location lachrymal sac by this device at lateral wall of nasal cavity.

Background technology

Along with improving and raising of health care level, in the 26S Proteasome Structure and Function design, all make every effort to therapeutic effect and use simple and direct unification for medical apparatus and instruments.

Chronic dacryocystitis is the existing common multiple disease of surgery, and particularly in the relatively poor area of sanitary condition, symptom is that the patient often sheds tears and suppurates, and has not only brought inconvenience to patient's life, and can concurrent other position inflammation when patient's whole body resistance descends.Cause the suppurative inflammation of other body parts sometimes, or even threat to life, therefore need treatment energetically to handle.Existing current treatment means is, carries out dacryocystorhinostomy and the lachrymal sac nasal cavity is made leakage art, and this type of modus operandi is adopted by most of hospital.

Lachrymal sac is positioned at the fossa for lacrimal sac of people's the forward lower inner wall of eye socket, its medial wall is adjacent by the lateral wall (being equivalent to the agger nasi position) of skim hone lamella and nasal cavity, before operation, need local anesthesia and contraction mucosa blood vessel are wherein carried out in this position, reach the purpose of hemostasis and pain-relieving in art.

If inaccurate in the art prelocalization, when cutting nasal membrane in the operation, the mucosa breakage can cause a large amount of losing blood, and makes operating time prolong, increase patient's misery.The certain difference of the textural existence of patient physiological is in addition made Lou and also can be caused bigger wound to patient's nasal cavity in the art carrying out the lachrymal sac nasal cavity.

Based on the limitation of existing armarium of basic unit and surgical experience, when stating operation on the implementation, determine that accurately lachrymal sac just seems comparatively difficult in the position of nasal cavity, there is bigger blindness, success rate of operation is lower, expense is higher.

The utility model content

Nasal cavity lachrymal sac positioner described in the utility model, its purpose are to address the above problem with deficiency provides lateral wall of nasal cavity brightness at patient's lachrymal sac insertion optical fibers, lachrymal sac is accurately located in art with auxiliary doctor.Through superior canaliculus (or lower lacrimal canaliculi), this device is arranged with fibre-optic sleeve pipe inserts lachrymal sac, and see through lateral wall of nasal cavity light is provided near lachrymal sac, thereby make the doctor can position lachrymal sac exactly from the nasal cavity exterior side wall, thereby need not by means of other accurate medical apparatus and instruments, surgical experience requirement for the doctor is lower, and operating time is short, and the patient does not have tangible pain sensation.

For realizing above-mentioned purpose of design, described nasal cavity lachrymal sac positioner has:

One connects the optical fibers of external light source;

At the sheathed sleeve pipe of described fibre-optic leading section, and close on terminal position at it and be provided with a light-emitting window;

At the described telescopic terminal one handle that connects.

As the nasal cavity lachrymal sac positioner of above-mentioned structure, make Lou at dacryocystorhinostomy and lachrymal sac nasal cavity and need not accurately to locate lachrymal sac in the art by means of other accurate medical apparatus and instruments.

Hold handle operation process traditional Chinese medical science green hand, inside is held the lacrimal ductule insertion of fibre-optic sleeve pipe along the patient.In the time of near tube ends arrives lachrymal sac, can locate lachrymal sac by means of the telescopic light that light-emitting window provided that closes on end.

The optional usefulness of described sleeve pipe has the material of certain degree of hardness, and guaranteeing in inserting the process of nasal cavity, its inner optical fibers can excessive bending and lose.

Described telescopic light-emitting window can be arranged on its end, also light-emitting window can be arranged near on the sidewall of end.The sleeve pipe light-emitting window is provided with the difference at position, is applicable to the different focus situations of patient's nasal cavity lachrymal sac.

At the constructional difference of patient physiological, described telescopic end can have a bending part.Described telescopic terminal bending part is fit to the dark patient's of eye socket insertion is used.

The radial angle of its bending part and sleeve pipe is in 5-10 ° scope.

Be difficult for slippage for making things convenient for the doctor to use in art, further improvement project is that described handle has the column profile, and is formed with screw thread in outer wall surface, the frictional force when holding with increase.

Be arranged near the situation on the sidewall of end corresponding to described telescopic light-emitting window,, an identification point be set on the outer wall of handle in the same side of light-emitting window.The purpose that this identification point is set is, when sleeve pipe is inserted into patient's lachrymal sac, by the identification point that exposes promptly know light-emitting window in lachrymal sac towards.Therefore, can regulate described light-emitting window towards, make the light cover to the nasal wall mucosa, be beneficial to the doctor and observe the bright spot position.

Be provided with scale at described telescopic outer wall, be beneficial to know clearly the distance that sleeve pipe is advanced in the process of sleeve pipe through lacrimal ductule, tear house steward, arrival lachrymal sac.

Described optical fibers is the medium of conducting light, and the one end connects light source, the other end described telescopic end that goes directly.

As above content, use the advantage of described nasal cavity lachrymal sac positioner to be:

1, providing lateral wall of nasal cavity brightness by inserting optical fibers at patient's lachrymal sac, can be so that the doctor can position lachrymal sac exactly from lateral wall of nasal cavity, operating time is short, and the patient does not have tangible pain sensation, and is convenient and swift, accuracy rate is high;

2, described nasal cavity lachrymal sac positioning device structure is simple, and cost is low and be easy to promote the use of;

3, adopt described nasal cavity lachrymal sac positioner to carry out dacryocystorhinostomy and the lachrymal sac nasal cavity is made leakage art, lower for the requirement of medical condition and surgical experience, be applicable to basic unit and the relatively poor hospital of medical care condition.
