RU191361U1 - Claw tweezers for the release of connective tissue structures in patients with connective tissue dysplasia - Google Patents

Abstract

The utility model relates to medicine, namely to devices used in surgery. Claw tweezers for releasing connective tissue structures in patients with connective tissue dysplasia consist of two branches connected to each other from one edge and expanding from the opposite edge, while the extensions of the branches have an area of at least 1 cm, have a trapezoid shape with a wide base, facing outward, have at least 3 grooves with a depth of at least 1 mm and at least 3 protrusions arranged so that when the jaw is closed, the protrusions and grooves of the opposite jaws go into each other, while securing them in the grooves Artificial corundum crystals not exceeding 0.5 mm in size are provided.

Description

The technical field to which the utility model relates.

The utility model relates to medicine, namely to devices used in surgery.

The level of technology. When carrying out surgical operations, the surgeon often faces the need to create a dense, stable tissue connection at the site of surgery. This is achieved either by plastic surgery, or by using artificial formations (implants, reinforcing nets), or by the introduction of drugs that stimulate scar formation. In the presence of connective tissue dysplasia, patients have an increased tendency to form scar tissue. With additional damage to the connective tissue formations (aponeurosis, fascia, ligament or connective tissue cord), the formation of scar tissue with the multidirectional position of the fibers occurs. This is based on the use of the claimed device.

Known (analogue) Tweezers universal [RF patent for utility model No. 28013 from 08/06/2002]. This device is a “tweezers consisting of two jaws connected by a fixing device, characterized in that the jaws are separate, one of the jaws has a through window and the other is made with a fixed lock, at the end of which there is a protrusion for interacting with the through window and turning 90 ° until it stops forms a fixed lock of both branches. "

The disadvantage of this device is that the tweezers have a small grip zone, the presence of separable parts makes it difficult to sterilize and increases the likelihood of multidirectional deformation of the components during heat treatment.

As a prototype, "Tweezers for implantation of an alloplastic material in rhinoplasty" was used [RF Patent for Utility Model No. 86439 of 09/10/2009]. It consists of two jaws interconnected up to 12.0 ± 1.0 cm long, while at the distal ends the jaws end with expanded cheek pads 8.2 ± 2.0 mm wide and 2.4 ± 0.2 cm long, for holding alloplastic material.

However, the use of this device during a surgical operation is associated with a number of inconveniences.

1. The tweezers do not allow you to firmly fix the object.

2. The tweezers do not allow the softening or razvolennost captured trapped connective tissue structure.

Utility Model Disclosure

The authors propose claw tweezers for the release of connective tissue structures in patients with connective tissue dysplasia, consisting of two branches connected to each other from one edge and having an extension from the opposite edge, while the extensions of the branch have an area of at least 1 cm ² , have a trapezoid shape with a wide the base facing outward have at least 3 grooves with a depth of at least 1 mm and at least 3 protrusions arranged so that when the jaw is closed, the protrusions and grooves of the opposite branches come into each other, when Volume in the grooves is fixed crystals of artificial corundum with a size of not more than 0.5 mm.

The device we offer has several advantages:

1. Tweezers allows you to rigidly fix the object due to the trapezoidal expansion of the ends of the branches and due to notches and protrusions

2. Tweezers allow softening or razvolennost captured trapped connective tissue structure, because when you close the jaws, the protrusions and grooves of the opposite branches come into each other, and crystals of artificial corundum, fixed in the grooves tear and scratch the fabric.

The technical result of the use of the proposed device is the softening and disengagement of the connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord) during surgery in patients with connective tissue dysplasia to form scar tissue with the fibers in different directions, which enhances the scar.

To characterize the utility model, in particular, the following features of the device are used:

branch extensions have an area of at least 1 cm ² ;

extensions of the jaw are trapezoidal with a wide base facing outward;

jaw extensions have at least 3 grooves with a depth of at least 1 mm and at least 3 protrusions arranged so that when the jaw is closed, the protrusions and grooves of the opposite jaws go into each other; - in the expansion grooves of the jaw crystals of artificial corundum are fixed with a size of not more than 0.5 mm

Utility Model Implementation

The claimed device can be applied as follows:

sterilization of the device is carried out in the manner adopted in this medical institution;

in the operating room, surgical access is made, the necessary manipulations are performed to dissect with a scalpel or cut with scissors of the connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord) - for example, aponeurosis with inguinal hernia repair;

before stitching the connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord), it is released by compressing it with tweezers and pulling through the compressed extensions of the branch;

due to the breakdown of the connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord), active formation of scar tissue occurs with the fibers in different directions, which strengthens the scar and prevents mesh implants from conducting plastic surgery.
