RU57104U1 - DISPATOR FOR SUBMISSIBLE ASPIRATION VASOTOMY - Google Patents

Abstract

Raspator for submucosal aspiration vasotomy. It can be used in the surgical treatment of patients with lower turbinate hypertrophy. The design of the new tool implements the ideology of creating the best conditions for obtaining minimally invasive surgical intervention performed simultaneously, with little trauma and with an exhaustive result. The claimed raspator has an oval hole at the end of the cutting part, facing the bony skeleton of the nasal concha, the edges of the hole have a cutting sharpener for disintegration of cavernous tissue, the configuration of the raspator tends to expand from the cutting part to the handle, which excludes obturation of the instrument during cut cycle with cut tissues. Design features of the raspator allow minimally injuring tissue.

A new technical result that can be achieved by the claimed technical solution is to reduce trauma, to prevent the formation of hematoma, bleeding, atrophy of the mucous membrane in the nasal cavity and the formation of perforation of the nasal septum, and to shorten the duration of the operation.

Description

The utility model relates to medicine and can be used in the surgical treatment of patients with lower turbinate hypertrophy.

A known tool for the surgical treatment of hypertrophy of the lower nasal concha ("Guide to otolaryngology" edited by A. G. Likhachev, 1981, pp. 110-112) in the form of a loop or scissors for the mechanical removal of hypertrophied sections of the lower nasal concha.

Bleeding is stopped by tight gauze tamponade, leaving it in the nasal cavity for 48 hours. The number of complications of a vasotomy performed using known instruments reaches 25%, due to the invasiveness of the operation, bleeding in the postoperative period, and atrophy of the mucous membrane, often with the development of perforation of the nasal septum.

Complications are associated with excessive trauma to tissues in the nasal cavity, a significant defect in the mucous membrane and lower nasal concha.

The objective of this technical solution is to achieve rapid rehabilitation of patients and reduce the time of temporary disability.

To solve the task in the design of the new tool, the ideology of creating the best conditions for obtaining minimally invasive surgical intervention, carried out simultaneously, with little trauma and with an exhaustive result, was implemented. The claimed raspator has an oval hole at the end of the cutting part facing the bony skeleton of the nasal concha, the edges of the holes have a cutting sharpening for disintegration of cavernous tissue, configuration

raspator has a tendency to expand from the cutting part to the handle, which eliminates the obturation of the tool during the working cycle with cut tissues. The above design features of the raspator allow minimally injuring tissue.

The most preferred site of access to the cavernous tissue of the inferior nasal concha is its anterior end. The mucous membrane in the specified anatomical zone has sufficient elasticity and is an ideal place for the formation of a tunnel along the bony skeleton of the lower nasal concha.

A new technical result that can be achieved by the claimed technical solution is to reduce trauma, to prevent the formation of hematoma, bleeding, atrophy of the mucous membrane in the nasal cavity and the formation of perforation of the nasal septum, and to shorten the duration of the operation.

The utility model is illustrated in the figure, which shows a raspator having a handle with a wide part 1, a transition part 2, passing into the cutting part 3. The configuration of the raspator expands from the cutting part to the handle. At the end of the cutting part, an oval hole is made, the edges of which have a cutting sharpening for disintegration of cavernous tissue.

The use of a raspator is implemented in submucosal aspiration vasotomy, which is performed as follows. After preliminary anesthesia and bipolar coagulation of the anterior end of the inferior nasal concha, a 3 mm long incision is made, a tunnel is created with a 3 mm wide raster along the entire length of the bony skeleton of the lower nasal concha.

The cutting part of the raspator connected to a vacuum trap is introduced into the formed tunnel and reciprocating and circular motions are performed. At the same time, in the dosed mode, the cutting part of the instrument is destroyed and at the same time the cavernous tissue of the lower nasal concha is removed.

The operation is completed with tamponade of the nasal cavity with a Surgicell sponge.

Example. Patient Peninsula, 35 years old. Complaints of difficulty in nasal breathing for about 4 years, resulting from a nose injury. When endoscopy revealed hypertrophy of the lower nasal concha. On a computer tomogram of the nose and paranasal sinuses - the true bone hypertrophy of the lower nasal concha is determined.

General condition is satisfactory. Pulse 80 beats per minute, blood pressure 135/80 mm. there is no mercury column, pathology from the cardiovascular system, parenchymal organs of the abdominal cavity, no chest organs were found.

Preparation for the operation is traditional. The operation was performed as described above. 42 people were operated on, complications in the form of bleeding, adhesions, atrophy of the mucous membrane, perforations of the nasal septum were not observed.

Studies have shown that the use of a patented tool provides a significant reduction in the number of complications and allows for quick rehabilitation of patients.

Claims (1)
