Abstract

The inventive surgery needle (1) is made of a metal, polymer or biological material, is provided with two acute ends (2, 3) and a surgical thread (5) fixing element (4) which is embodied at any section of the needle at a certain distance from the ends thereof. Said needle is usable in two directions and is straight-shaped or curve-shaped in circular direction. The inventive method for plastic surgical operation consists in introducing said double-pointed needle into subcutaneous tissues along a traced outline, in partially extracting said needle from the skin at each stitch thereof, in carrying out the following entry stitches by the opposite end of the needle, in carrying out the final exit stitch in the direction of the initial entry stitch, in pulling the subcutaneous tissues by using both ends of the thread according to a surgical program and in applying an attachment point for fixing the surgical thread. The inventive method makes it possible to carry out the entry stitch at the point of the exit stitch thereof, thereby smoothly stitching the subcutaneous tissues without drawing the skin.

Description

 Surgical needle and method for performing plastic surgery

The invention relates to medicine, to tools and methods for performing surgical plastic operations. In particular, the invention relates to medical materials used in surgery for plastic cosmetic surgery.

State of the art

Surgical needles for suturing the edges of wounds during surgical operations are known (J. Zoltan, “Operational technique and conditions for optimal wound healing”, “Medicine”, Budapest, 1977) They are made of metal, more often steel, needles are straight, bent along a circle or other shape. The needles are pointed at one end, and the suture surgical suture is attached to the other. For plastic and aesthetic operations, atraumatic needles are most often used, which have no eye and the suture thread is attached to the needle in a factory way, which allows the surgeon to use a disposable sterile suture material, and most importantly, a needle that does not have a rough eye and a double thread. Such a needle slightly injures soft tissue when passing through them. General characteristics of surgical needles: strength, smooth surface, bioinertness. They should easily pierce the skin and pass freely through the subcutaneous tissue.

SUBSTITUTE SHEET (RULE 26) Known methods for applying surgical sutures with the help of such needles, which are usually used for suturing wounds, or suturing subcutaneous tissues: nodular, mattress, continuous and others. Suture of subcutaneous tissue is performed only in an open wound, or during endoscopic surgery. Such techniques are usually used by aesthetic surgeons to stitch, tighten ptosis subcutaneous tissues and strengthen them in a new, higher position, which provides a better aesthetic option.

However, often there is a need for flashing to tighten soft tissues without external incisions, but such needles do not allow this procedure to be carried out qualitatively.

If you need to pierce a certain area of soft tissue with existing suture material with such needles, you need to pierce the skin, make a needle and pull the needle with thread to the surface of the skin, then inject the needle into the needle exit point, draw the needle along a new contour, make another needle and inject the needle with thread , then again inject the needle into the withdrawal point, draw the needle with the thread towards the initial needle injection and here pulling both ends of the thread to lay a knot. Sewing and tightening of this area of soft tissues will take place, but at all points of the needle exit to the skin surface, a rough skin retraction will result, since it is almost impossible to return the needle tip to the same channel in which the thread passed. Therefore, this technique is not used.

SUBSTITUTE SHEET (RULE 26) Disclosure of invention

The problem is solved in that the surgical needle, made of metal or other material, is made double-edged, straight or of any curved shape with a surgical thread attachment element located along the length of the needle in any place, not reaching a certain distance to the needle tips.

The method of performing cosmetic surgery, which consists in tightening the subcutaneous tissues, is characterized in that a double-edged needle is injected into the subcutaneous tissues along the intended contour and is not completely removed from under the skin with each turn, and further injections are performed with the opposite sharp-end of the needle, while providing a further injection needles at the point of her puncture, and the surgical thread provides high-quality smooth flashing of the subcutaneous tissues, and the final puncture of the needle is carried out to the side to the point of its initial injection, then under subcutaneous tissues are pulled at both ends of the suture as indicated by the operation and a surgical suture attachment site is imposed.

Depending on the nature of the operation, the needle may be straight, curved in a circle or other shape.

The basis of the present invention is the creation of a surgical needle for cosmetic operations with double-sided patency, which ensures its passage under the skin along a broken or long contour without its complete withdrawal to the skin surface, which will allow the thread to pass under the skin and subcutaneous flashing of soft tissues without skin retraction and get an even tightened contour.

SUBSTITUTE SHEET (RULE 26) Brief Description of the Drawings

In the future, the invention is illustrated by drawings, in which:

FIG. 1 - depicts a double-edged needle of a straight form

FIG. 2 - depicts a double-edged needle circumferentially bent

FIG. 3 - schematically shows a method of conducting an operation

FIG. 4 is a schematic illustration of an operation

The main embodiment of the invention

The surgical needle 1 is double-edged with the pointed ends 2 and 3 made of metal, polymer or other biological material. The fastening element 4 of the surgical suture 5 is located anywhere on the needle along its length without reaching a certain distance to its tips. The needle has a two-way cross and can be straight 1 or curved in a circle 6.

To illustrate a method for performing plastic surgery, FIG. 4 is an example of tightening the soft tissues of the cheek-cheekbone area, creating a higher, aesthetically beneficial contour of this part of the face.

The needle punctures the skin at point 7, in the temple area, within the hairline and, together with the thread connected to it, is carried out subcutaneously along a certain contour, then

SUBSTITUTE SHEET (RULE 26) puncture and incomplete withdrawal of a needle with a thread on the surface of the skin.

The tip of the needle should remain in the subcutaneous tissue, at point 8. Then, the needle is deployed under the scythe towards the point 9 and punctured at this point and its incomplete withdrawal to the skin surface is also performed. Here, the needle is also deployed subcutaneously, but already in the direction of point 7 and drawn along a new contour to this point, that is, the point of initial injection. At this point, both ends of the thread are pulled together, tied together in a strong knot, which is recessed under the skin.

Thus, a stitched and tightened area of soft tissues of the buccal-zygomatic region is obtained without external incisions, without rough skin retracts, with an even, smooth contour. Similarly, an operation is performed on the opposite side.

Industrial applicability.

As shown in the description, the present invention can be widely used in various cosmetic and plastic surgeries, both independently and in combination with other surgical interventions. The proposed surgical needle and a method for performing plastic surgery are industrially feasible, manipulations using a double-edged needle are simple and bloodless.
