RU56799U1 - SURGICAL SCISSORS FOR CUTTING CARTILAGE OF THE LARYNX - Google Patents

Abstract

The utility model relates to the field of medicine, and more specifically to surgical instruments used in surgical intervention in the larynx. The purpose of creating a utility model is to reduce the morbidity and increase ease of use when dissecting the cartilage of the larynx. Surgical scissors for dissection of the larynx are DIFFERENT in that the working jaws are bent at an angle of 15-25 degrees relative to the plane of the jaws, with the length of the working jaws being 65-70 mm and the width of the working jaws being 10-12 mm. 1 pf, 2 ill.

Description

The utility model relates to the field of medicine, and more specifically to surgical instruments used in surgical intervention in the larynx.

Known scissors containing co-located rods with a handle at one end and cutting blades at the other (1).

The disadvantage of these scissors is the inability to use them to dissect the cartilage of the larynx.

Known surgical scissors containing articulated jaws with cutting edges and handles (2).

The disadvantage of these scissors is increased trauma during their use.

A device for resecting segments of a tubular organ, containing cutting elements and handles (3).

The disadvantage of this device is the increased complexity and invasiveness when dissecting the cartilage of the larynx.

Surgical nippers are known, containing articulated jaws with spring-loaded handles at one end and working jaws at the other (4).

The disadvantage of these nippers is increased trauma during dissection of the cartilage of the larynx.

Surgical scissors are also known containing pivotally intersecting jaws with spring-loaded handles at both ends of the jaw and with working jaws at the other ends of the jaw (5).

The disadvantage of these surgical scissors is the increased complexity and inconvenience of use associated with increased trauma during dissection of the cartilage of the larynx due to the fact that the dissection must be performed in two to three doses.

The purpose of creating a utility model is to reduce the morbidity and increase ease of use when dissecting the cartilage of the larynx.

This goal is achieved by the fact that the working jaws are bent at an angle of 15-25 degrees relative to the plane of the jaws, and the length of the working jaws is 65-70 mm, and the width of the working jaws is 10-12 mm.

A comparison of the proposed surgical scissors with others, known in the field of medicine, showed its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material. Figure 1 shows the proposed scissors, a top view, figure 2 is a surgical scissors, side view.

The proposed surgical scissors for dissection of the cartilage of the larynx include joints using a hinge 1, intersecting branches with handles 2 and 3 at both ends with working jaws 4 and 5. Between the handles 2 and 3 there is a spring 6, working jaws 4 and 5 are bent at an angle equal to 15-25 degrees with respect to the plane 7 of the location of the branches to the plane of the location of the handle 2 and 3. The length of the working jaws 4 and 5 is 65-70 mm, and the width is 10-12 mm.

The proposed scissors for dissection of the larynx are used as follows.

During the operation, the patient's head is thrown back with a roller under the shoulders. Manipulation is performed under general anesthesia, intubation is carried out through a tracheostomy or oropharyngeal.

The skin is cut along the midline of the neck in the area of the thyroid cartilage in the borders from the hyoid to the upper edge of the cricoid cartilage, then the front muscles of the neck are moved apart, and the anterior part of the thyroid cartilage is exposed. Using a scalpel in a sharp way along the midline at the upper edge of the thyroid cartilage, soft tissues are dissected with penetration into the laryngeal cavity. One working sponge along the sagittal axis of the vertically anterior surface of the neck is inserted into the lumen of the larynx and

unfolds in the midline 90 degrees, facing the chin with the handles. The angle of curvature of the instrument X allows you to freely dissect without any interference with the chin and body of the jaw due to the narrow and long working jaws, without injuring the mucosa of the distal parts of the larynx, into the lumen along the entire length of the proposed cartilage resection line.

The length of the working jaws is 65-70 mm, their width equal to 10-12 mm and the limb angle of 15-25 degrees are optimal for manipulations to dissect the cartilage of the larynx. Increasing or changing these sizes creates inconvenience to use and can cause additional injuries.

The use of the proposed surgical scissors is possible and appropriate in the surgical units of medical institutions both in the treatment of patients with tumor diseases of the larynx of various origins, and in various reconstructive operations on the larynx.

Using the proposed surgical scissors allows to obtain a qualitatively new positive effect: the length of the working jaws is 65-70 mm and the width of 10-12 mm makes it easy to manipulate on the cartilage of the larynx, the working part is inserted into the lumen of the larynx without excessive injury, thereby not injuring the mucous membrane of the posterior sections . The curvature along the plane of the working part and the handles of the scissors allows you to work along the midline without interference to the handle with the chin of the patient. The power of the scissor design allows you to easily dissect the thyroid cartilage and enter the lumen of the larynx without much effort.
