RU61550U1 - OPHTHALMIC HOOKS - Google Patents

Abstract

The proposed device hooks for ophthalmology is designed to fix the edges of the wounds during surgical operations. To do this, stainless steel hooks containing a curved working part and elements for handling during use are made of wire segments with a cross-sectional diameter of 0.4-0.5 mm, bent and pointed from the working ends and rolled into a closed loop at the opposite end for fastening the elements providing manipulation during use, which can be performed in the form of segments of a flexible ligature thread, one end of which is tied to a closed loop of a hook, and the other may have a counterweight ball.

Description

The proposed device relates to a medical instrument, in particular to ophthalmic means for fixing the edges of wounds during operations on the eyelids, sclera, conjunctiva.

To fix the edges of the wound in ophthalmological operations, special hooks with curved pointed ends and handles are used to manipulate them (see Industry Catalog Informpribor M., 1989, “Automation Devices and Means 9.” Medical equipment, 9.2.1 Medical instruments ..., p. 60, CODE 943431 3011 and 94 3431 3006 or retractors p. 44 CODE 943411 0061). Manipulations with these tools are performed by an assistant, while the surgical field is blocked by an instrument, which complicates the actions of the surgeon and limits the work of the assistant. Thus, these tools do not provide optimal conditions for the operation.

A device is known for the hook-eye lift, containing a handle, a neck and a working part curved relative to the neck (see AS No. 219092, IPC A 61 F 09/00, publ. 1968.). The design of this device can be considered as the closest analogue of the patent information, however, this tool has a slightly different purpose than the proposed device.

The technical task of the proposed design of the ophthalmic hooks is to create a design convenient for fixing the edges of the wounds during surgical operations on the eyelids, sclera and conjunctiva.

The problem is solved due to the fact that the stainless steel ophthalmic hooks are made of wire segments with a cross-sectional diameter of 0.4-0.5 mm, bent and pointed from the working ends and rolled into a closed loop at the opposite end, for fastening the elements, providing manipulation in use. At the same time, the elements for manipulation can be made in the form of segments of a flexible ligature thread, one end of which is tied to a closed loop of a hook, and the other can be equipped with a counterweight ball.

The proposed device designs can be either single or double hooks with a working part length of up to 10 mm. The double hook can be made of a piece of wire with a length of about 40 mm, which bends in the middle with the formation of a loop for attaching manipulation tools.

Figure 1. shows the manufacturing options of the proposed hooks. The hooks include the working part 1 with a curved pointed segment 2 and a loop 3, with a ligature thread 4 tied to it, at the end of which a counterweight ball 5 can be fixed.

To fix the edges of the wound with hooks, these edges are bred by them to the required distance, and the ligature thread 4 is fixed to the eye cup with a clip. It is also possible to fix the edge of the wound using a counterweight ball 5.

The use of the proposed tools frees up the surgical field, which allows you to change the strategy of the operation depending on its nature, increases the efficiency of the assistant’s actions, and reduces the invasiveness of the operation.

Claims (5)
