Description

ophthalmic device1

The device for ophthalmoendosurgery refers to medical ophthalmic instruments and devices.

In ophthalmoendosurgery, various constructions of devices and instruments known to expose the internal tissues of structures to laser radiation are known; eyes, the case of such a device is made in the form of a small tube, a fiber guide is placed in it and it is inserted through the sclerosome of the eye to the inner tissues of the retina eye, the disadvantage of all known designs of such devices is the lack of protection of the laser radiation exposure zone.

for example, in ophthalmology a device for ophthalmic surgery is known, ohm. ao, USSR -№l 24I8 dated 14-06 .., A6IB 17/06, A6IP 9/00, containing fiber optic fibers located in the housing, optically coupled to a working laser operating in the invisible infrared range of light, marker laser oftal / yuzndoscope with an instrument channel in which a fiber is placed that are optically paired with a laser marker; the device is made in the form of a small tube with a diameter of I-2MM. the doctor, introducing through the sclerosome, brings the distal end of the device casing to the exposure zone, turns on the laser radiation and performs surgical intervention.

The disadvantage of such a device is the lack of protected nearby eye tissue © the area of exposure w. in the case of the location of the pathological focus / mooring, pre and subretinal membrane / directly at the retina, the transmitted laser radiation

Zera radiation with a wavelength of 1, insufficiently absorbed by the intraocular structure d / w.

The closest solution is the design of the device for ophthalmic endosurgery, see prospectus file pvшl Ness / ccat En-oLop oie. containing a fiber light guide, housed in a tube-shaped housing, and optically coupled 1: and with a laser.

The operation of the device consists in eating, introducing through the sclerosis the distal and the end of the device’s body, they bring the end of the fiber to the area of influence, including laser radiation and performing surgical intervention,

The disadvantage of such a device was the lack of protection of nearby tissues in the affected area, which can lead to trauma to the structure of healthy eye tissues.

the technical result of using the proposed device is to reduce herbs U1atization of eye structures.

The result is achieved by the fact that in a device for phthalloendosurgery containing a fiber waveguide, located in 1 1 in the case and optically coupled to the far end with a laser, a surgical instrument is installed at the distal end of the device case, an instrument completed in the form of a cup, the distal end of which is made in in the form of a spatula.

The essential features of the device, which coincide with the recognition of the prototype, are the presence of a fiber light guide located in the housing and optically coupled to the laser.

an essential distinguishing feature of the device according to the technical result achieved is that a surgical instrument mounted on the distal end of the cortus is introduced in the device, made in the form of a scream, while the distal end is made in the form of a spatula, which allows fixing the irradiated

eye tissue and protect healthy eye tissue from laser radiation :.

a device for ophthalmic endosurgery is shown in the drawing 1,2.

In the drawing of FIG. 1, a cross-sectional view of the main view of the device, shown in Fig. (rig.2-section Dystalnyzh the end of the spatula of a surgical instrument.

The device of the Ophthalmic Endosurgery DEA contains the fiber optic fiber of Fig. 1, located in cortus 2 and optically paired with the laser at the droximal end. Surgical instrument 4 is installed at the distal end of the casing 2 ycTpOj / iCTBa 5 in the form of a contour 5 with a beveled 6- Detailed end of scream 5 filled in the form of a spatula of figure 2, i.e. in the form of a platform, and placed in front of the sculpted fiber i. the diameter of the housing I, which is entirely in the form of a capillary HOju tube, is 0.9 mm, the size of the spatula is 1.2 mm, the distance from the distal® end ВШ1 of the window guide to the end of the hook is 2 mm,

The operation of the device is as follows. the distal end of the casing 2 with the fiber optic fiber i and the surgical instrument are inserted through the sclerosome into the inner region of the eye, brought to the affected area, with the extra 5 grasp: the irradiated tissue and place it in front of the crimson pad in front of the skinny fiber optic cable i, illuminating and examining it with microscope through the optical medium of the eye. Then, the laser is turned on and the surgery is performed and the action of laser radiation.

the device for ophthalmic endosurgery according to protrusion allows to reduce the trauma of the internal eye structures surrounding the affected area and located behind the irradiated tissue, due to the fact that a surgical instrument is installed at the distal end of the device’s body, filled in ideally with a cord placed in front of the end of the fiber and pulled out in the form of a spatula , tkl :. taki1 1 tool can be fixed © blushush our eye tissue, protect

healthy tissues located around the zone. ascension and tissues located behind the irradiated tissue §, and to screen coagulating laser radiation, in addition, it is possible to use a spatula to carry out precision mechanical exfoliation from dissecting eye structures / mooring, membranes, scars, etc. / adjacent directly to the retina. D ansham tool significantly facilitates retinomy, because due to one-show (the 11th x-ray of the retina creates the best conditions for its dissection by laser radiation, the device has been tested in practice, it has shown good results, better medical characteristics, and it’s quite convenient to work.
