RU77769U1 - Tweezers for Microsurgical Surgery on the Eye Drain - Google Patents

Abstract

Tweezers for microsurgical operations on the drainage paths of the eye are proposed, which are two branches, one of which has a protruding pointed tip in the form of a needle. To ensure that a given gap between the jaws is obtained, a twisted-neck clamp is installed on the tweezers, which when it is moved to the tweezers tips compresses the jaws to the required level, and the use of a permanent magnet clamp ensures the fixation of the specified gap between the jaws.

Description

Tweezers for microsurgical operations on the drainage of the eye. The utility model relates to the field of microsurgical ophthalmology and, in particular, to devices used during microsurgical operations on the drainage paths of the eye.

State of the art

Known devices for the removal of tear fluid in glaucoma are a drainage device in the form of a tube or channel implanted in the eye connected to the anterior chamber of the eye. Typically, the tube is inserted into the anterior chamber transsclerally or translimally, attached with sutures, sometimes covered with a donor sclera or allotissue. (see, for example, patent No. 53894 of June 10, 2006). However, tweezers are also necessary for manipulating it during surgery. In ophthalmosurgery, various types and shapes of tweezers are known that are used for microsurgical operations for glaucoma, including for fixing drains. However, when conducting operations on drainage channels, especially in operations with manipulation during the installation of tubular drainage, they are inconvenient. And, as practice has shown, the need has emerged to have the tips of the working branches of the tweezers, made with different profiles. Experience has shown that for the convenience of work, in order to reliably fix the tubular structures, it becomes necessary to have one of the branches of the tweezers pointed in the form of a needle.

In addition, during the operation, it is necessary to keep the forceps branches compressed at a fixed distance from each other

friend, and this distance should make it possible to change it depending on the characteristics of the patient’s eye. Thus, in the process of manipulation it is necessary to be distracted by a fixed retention of tweezers with a given gap jaws. This is inconvenient and distracts attention from the main operation. Better tweezers are proposed to remove these drawbacks.

SUMMARY OF THE INVENTION

A utility model (tweezers) is shown in Figs. 1 and 2.

The tweezers for microsurgical operations on the drainage pathways of the eye (see Fig. 1) are two branches, one of which (1) has a protruding pointed tip in the form of a conical needle. (2A), and the other (2) has a compression stop (3) branch Homutik (4) is installed on the tweezers with a tapered cut inside, which allows you to change the gap between the branches using its axial movement along the branches. The tweezers are made of steel or other magnetic material, and the clamp is made of a permanent magnet, which ensures that the gap is maintained in a given size.

Thus, the proposed tweezers differs from those currently used by the presence of one jaw tip pointed in the form of a needle and the presence of a movable clamp with a taper cut made of a permanent magnet, which ensures that this position is fixed when set to a predetermined size.

Claims (2)

1. Tweezers for microsurgical operations on the drainage of the eye, consisting of two branches and an emphasis, characterized in that the tip of one of the branches is made in the form of a needle, and the specified gap of the branches is provided using a clamp having an internal cutout in the form of a cone. 2. The device according to claim 1, characterized in that the clamp is made of magnetic material.
