RU55283U1 - DEVICE FOR FIXING OPERATING CONTACT LENS - Google Patents

Abstract

The utility model relates to medicine, namely to ophthalmology and is intended for vitrectomy and operations for retinal detachment. The device for fixing the operating contact lens on the patient’s eye is a washer, the inner surface of which forms two adjacent cavities, the shape of the lower one corresponding to the shape of the eyeball and the shape of the top corresponding to the shape of the inserted operating contact lens. The washer may have four holes on the outer perimeter to hem the device to the sclera. The washer can be made of Teflon. After anesthesia and preliminary manipulations, a device is applied to the patient’s eye and is sutured to the sclera with four sutures. After that, an operational contact lens is inserted inside the device and manipulations are performed according to the operation procedure. After their completion, the lens is removed from the device, the seams fixing the device are removed, and it is removed. The technical result of the use of the device is a clear and reliable fixation of the operating contact lens in the right position, eliminating the need to use an assistant to hold it with tweezers, completely freeing the surgical field, increasing the possibility for the surgeon to manipulate and reducing the time for surgery.

Description

The utility model relates to medicine, namely to ophthalmology and is intended for vitrectomy and operations for retinal detachment.

To carry out these operations, operating contact lenses are used, for example, from silicone, which are selected depending on the purpose, are installed on the patient’s eye and are held in position by an assistant using tweezers (Product Catalog. Experimental and Technical Production “Eye Microsurgery” - M., 2003, p. 27, cat. No. 15-01).

The use of tweezers does not provide a sufficiently clear fixation of the lens and limits the manipulation of the surgeon; the surgical field is thus overlapped.

The problem being solved by the proposed utility model and the expected technical result are the development of a device for more precise fixation of operational contact lenses, not limiting the surgeon's manipulation and providing an open surgical field. Eliminates the need to use an assistant to hold the operating contact lens. The duration of the operation is reduced.

The problem is solved in that the device for fixing the operating contact lens on the patient’s eye is a washer, the inner surface of which forms two adjacent cavities, the shape of the bottom corresponding to the shape of the eyeball and the shape of the top to the shape of the inserted operating contact lens.

The washer may have four holes on the outer perimeter to hem the device to the sclera.

The washer can be made of Teflon.

The proposed device is presented in figure 1-2 (side view and top view, respectively).

Since the shape of the lower cavity of the washer corresponds to the shape of the eyeball, the device is quite clearly fixed on the patient’s eye. The presence of holes for stitching the device to the sclera increases the clarity and ensures reliable fixation of the device and, accordingly, the operating contact lens.

The location of the holes on the outer perimeter of the device is preferably symmetrical with respect to each other and pairwise in mutually perpendicular planes (figure 2).

The use of the device is illustrated in FIGS. 3-4.

The device is used as follows.

After anesthesia and preliminary manipulations, a device is applied to the patient’s eye and is sutured to the sclera with four sutures. After that, an operational contact lens is inserted inside the device and manipulations are performed according to the operation procedure. After their completion, the lens is removed from the device, the seams fixing the device are removed, and it is removed (Fig.3-4).

The optimal version of the device provides a particularly clear and reliable fixation of the operating contact lens in the desired position, eliminating the need to use an assistant to hold it with tweezers, completely freeing the surgical field, increasing the possibility for the surgeon to manipulate and reducing the time for surgery.
