RU52326U1 - DEVICE FOR FIXING A SCLERAL RAG WITH NON-PENETRATING DEEP SCLERECTOMY - Google Patents

Abstract

The utility model relates to medicine, namely to ophthalmology and is intended for antiglaucomatous operations. The device for fixing the scleral flap includes two parallel guides curved along the curvature of the cornea of the eye and connected by a jumper. Moreover, each guide is a lever bent along the curvature of the cornea of the eye in the working part; the parallel shoulders of the levers are connected: a jumper in the working part and a counterweight in the opposite part. Each lever is made of stainless steel wire by continuously turning it clockwise so that the support points of the levers are wire rings. The counterweight is made of stainless steel or another anti-corrosion alloy, weighing about 5 g, for example, in the form of a ball. The scleral flap is fixed by suturing it to the jumper and holding it in the desired position due to the counterweight. The surgical field remains fully open. The operation using the device, respectively, is less traumatic due to the reduction of its duration, including due to the need to impose a single seam. Surgeon manipulations are comfortable and free. The assistant is active during the operation, as it is released for other manipulations.

Description

The utility model relates to medicine, namely to ophthalmology and is intended for antiglaucomatous operations.

With non-penetrating deep sclerectomy (NSES), a flap is cut from the upper layer of the sclera with the base to the limb, turned away and held by the assistant with tweezers. With this method of fixing the scleral flap, the actions of the assistant are limited, and the surgical field is partially blocked.

A device for fixing a superficial flap of the sclera during subscleral antiglaucomatous operations / RF patent No. 20033317, A 61 F 9/00, publ. 11/30/1993. - prototype /, the body of which is made in the form of two horizontally connected and arranged in parallel planes guides with rounded ends, while the guides are equally bent congruent to the surfaces of the sclera and cornea.

The prototype is not effective enough due to the limitation of the surgical field by the device guides. The disadvantages of the prototype also includes the imposition of three seams when using it, which determines the duration and invasiveness of the operation.

The problem being solved by the proposed utility model and the expected technical result are to increase the efficiency of the device by providing an open operating field. An open surgical field, as well as fixing the scleral flap of the proposed device using a single seam, can reduce the duration of the operation and reduce its invasiveness.

The problem is solved in that in the device for fixing the scleral flap, including two parallel guides curved along the curvature of the cornea of the eye and connected by a jumper, each guide is a lever curved along the curvature of the cornea of the eye in the working part, and the parallel shoulders of the levers are connected by a jumper - in the working part and with a counterweight - in the opposite part.

Each lever is made of stainless steel wire by continuously turning it clockwise so that the support points of the levers are wire rings.

The proposed device is presented in figure 1.

The distance between the jumper and the fulcrum of the parallel levers is 10-12 mm.

The width of the jumper is 4-6 mm.

The counterweight is made of 13X stainless steel or another anti-corrosion alloy, weighing about 5 g, in the form of a ball, cylinder or cone.

The use of the device is illustrated in figure 2.

The device is used as follows. After cutting the flap from the upper layer of the sclera, the device is placed on the cornea so that

parallel shoulders of parallel levers connected by a jumper in the working part of the device were located symmetrically with respect to the diametrical axis passing through the middle of the flap. After that, the flap in its front upper part is sutured to the jumper of the device and in this position is fixed due to the weight (ball) of the counterweight located in the part of the device opposite to the working one (figure 2).

The stability of the device when fixing the flap is ensured by the fact that it is a double lever - consisting of two parallel levers.

The device is more effective than the prototype, since the surgical field remains completely open. The operation with its use, respectively, is less traumatic due to the reduction of its duration, including due to the need to apply a single seam instead of three according to the prototype.

Surgeon manipulations are comfortable and free. The assistant is active during the operation, as it is released for other manipulations.
