Description

The alleged invention relates to medicine, namely to medical instruments and can be used in the surgical treatment of auricular deformity - otoplasty.

Known pointed curved scissors (Atlas of surgical instruments Edition No. 2 of 2016. Performed by: Anton Osipenko Edited by: DeepestDepths, Nikolai Lisitsky, Stanislav Kirsanov, Julia Belova, TestPage), designed for dissection of soft tissues, cartilage and ribs due to the onward movement of the edges of the blades wedge-shaped. Design features of surgical scissors - surgical scissors have two blades that dissect tissue during oncoming movement; - the angle of sharpening of the blades of scissors, as a rule, is within 40 °.

Requirements for surgical scissors:

1. Ensuring high quality of the cut, regardless of the properties of the tissues.

2. Structural strength for longer life.

3. Maintaining constant properties of cutting edges for a long time.

4. Ensuring minimal effort applied to the handles by using the “lever effect”.

5. Reducing the likelihood of iatrogenic damage due to the design features of the ends of the blades.

Disadvantages:

Short blade length, insufficient usability, inability to make several parallel cuts at the same time, great trauma, laboriousness when making several cuts.

A scalpel was adopted as the closest analogue (Atlas of Surgical Instruments Edition No. 2 of 2016. Performed by: Anton Osipenko Edited by: DeepestDepths, Nikolai Lisitsky, Stanislav Kirsanov, Julia Belova, TestPage), intended for dissection of soft tissues. It is the most common type of surgical knife. From a number of varieties of scalpels for otoplasty, a standard surgical scalpel is used, which has a flat handle and at the same time a working part in the form of a sharp blade on one side

Use in otoplasty - using a standard surgical scalpel, consecutive parallel incisions are made on the posterior surface of the cartilage of the auricle.

Disadvantages:

the inability to make several incisions at the same time, the difficulty in combining parallel incisions on the cartilage of the auricle and incisions in the tissues of the ear region due to the insufficiently accurate length of the incisions, trauma, labor costs for a number of incisions. Tasks: Simultaneous implementation of several incisions, reducing the morbidity, reducing the duration of the operation in time, convenience for the surgeon in the operation of the instrument, achieving a given length and strictly parallel to each other incisions.

The essence of the invention is that on the working surface of the scalpel in the through holes are installed and rigidly fixed 10-12 mm apart from each other, two rods perpendicular to the surface of the scalpel, one of the rods is equipped with a screw thread and a nut, several detachable are thrown parallel to the rods each other of disposable blades, the cutting sides directed in the same direction as the cutting edge of the scalpel, and the blades are delimited from each other by metal, smaller, gaskets 0.5-1.0 mm thick., and the whole comp EKT blade is pressed by a nut on the stem plate on the upper blade.

Technical result:

the proposed tool allows you to simultaneously and simultaneously inflicted several incisions on the posterior surface of the cartilage of the auricle, reduce trauma due to a given depth of incisions, and achieve ease of use of the instrument.

For a better understanding, the tool is shown schematically with the distances between the disposable blades and the metal gaskets of FIG. 1 general side view, where:

1 - handle, 2 - working end of handle, 3 - through hole, 4 - screw threaded rod, 5 - nut, 6 - rigidly fixed rod, 7 - plate, 8 - disposable blades, 9 - metal gaskets.

The tool is used as follows:

They process the surgical field (alcohol solution), cover it with surgical sterile underwear. Local anesthesia begins with the introduction of a solution of 1% lidocaine in the upper third of the ear fold, the tissues are infiltrated in the direction of the earlobe, then 1% lidocaine is injected at the base of the curl and the earlobe along the front surface of the auricle, after which 1% lidocaine is introduced into the deepening of the auricle. Take the otoplasty tool by the handle 1, onto the screw rod 4 and the rigidly fixed rod 6, which are located on the working end 2 of the handle 1, draw the next such disposable blade, then a metal gasket 9 on it, then the next disposable blade, on which they also throw a metal the gasket 9, the next blade is laid on top, on top of which a plate 7 is thrown, the nut 5 is screwed onto a rod with a screw thread 4 with the condition of tight pressing of the blades. The tool is ready to use. Behind the auricle, a vertical incision is made of a spindle-shaped (wave-like) shape, the skin flap obtained during an incision in the area of surgical intervention is peeled off and removed.

Soft tissues on the posterior surface of the auricle in the surgical area are separated from the own cartilage of the auricle. At the same time, hemostasis is performed. Using a tool for otoplasty, in one motion, parallel incisions are made to the posterior surface of the auricle along the cartilage where an antihelix will be formed. The cartilage area for anti-helix is thinned with an otoplasty tool, which becomes more malleable for modeling, then the cartilage is fixed with several U-shaped sutures, due to which a fold of the anti-helix is formed. Then, if necessary, the fusiform (wave-like) form of part of the cartilage conchae is removed. The edges of the removed cartilage are connected by seams. This tool is used to simulate a cartilage site and form an anti-helix, which is usually not present with irregular shape (bulging) of the auricles. Suture the incision. External aseptic dressing.

The tool was tested on 317 patients aged 16-35 years. Results: in the early and late postoperative period, the sutures are consistent, there were no complications, postoperative scars without pathology, with the help of an otoplasty tool, it was possible to form a protector that was not there. A cosmetic effect is provided.

Example

Patient N., 17 years old. Received with a diagnosis of Deformation of the left auricle. It was decided to perform an otoplasty operation on the left auricle under local anesthesia.

They used a tool for otoplasty. Operation progress - AS: The surgical field was treated (alcohol solution), covered with surgical sterile underwear. Local anesthesia was performed - a solution of 1% lidocaine was injected into the upper third of the ear fold, the tissues were infiltrated in the direction of the earlobe. Then 1% lidocaine was injected at the base of the curl and lobe along the front surface of the auricle. Then they introduced 1% lidocaine into the deepening of the auricle. They took the otoplasty tool by the handle, threw a disposable blade, then a metal gasket on the screw rod and the rigidly fixed rod that are on the working end of the handle, then the next disposable blade, onto which the metal gasket was also thrown, put another blade on top of which they threw the plate, screwed the nut onto a screw-threaded rod and pressed the plate tightly, tightening the nut. The tool is ready to use. Behind the auricle, a fusiform (wave-like) incision was made, the skin flap obtained during the incision in the area of surgical intervention was peeled off and removed. Soft tissue on the posterior surface of the auricle in the surgical area was separated from the own cartilage of the auricle. At the same time hemostasis was performed. The spindle-shaped (wavy) shape of part of the cartilage conchae was removed. Edges joined by sutures, conchae reduced. Using a tool for otoplasty, parallel incisions were made to the posterior surface of the auricle along the cartilage, where an antihelix was formed. At the same time, we thin the cartilage section for the anti-helix, this allowed us to simulate it, then the cartilage is fixed with several sutures, due to which the fold of the anti-helix is formed. Suture the incision. External aseptic dressing.

Result: in the early and late postoperative period, the sutures are consistent, there were no complications, postoperative scars without pathology, with the help of an otoplasty tool, it was possible to form a protector that was not there. A cosmetic effect is provided.
