RU57585U1 - Aspirator for surgical treatment of nose and throat injuries - Google Patents

Abstract

Aspirator for the surgical treatment of nasal and laryngeal trauma. It can be used for short operations on nasal and pharyngeal cavities under intravenous anesthesia without endotracheal intubation. This technical solution is aimed at reducing postoperative complications during short operations on the nasal cavity and pharynx under intravenous anesthesia without endotracheal intubation.

The novelty of the claimed aspirator is the presence of three catheters, the suction channels of which are connected by a three-channel connector for connection to a vacuum device. Moreover, each of the catheters is equipped with perforations in the form of holes of different sizes, decreasing in the proximal direction. To reduce mucosal trauma, catheters made of thermoplastic material are the best, the density of which decreases at body temperature.

A new technical result that can be achieved by the invention is the simultaneous evacuation of contents from both halves of the nasal cavity and larynx.

Description

The utility model relates to medicine, namely, surgical otolaryngology and can be used for short-term operations on the nasal and pharyngeal cavities under intravenous anesthesia without endotracheal intubation.

A known aspirator for surgical aspiration of the nasal cavity and pharynx (Portex Product Catalog, 2004, pp. 16-18). The known aspirator is a single-channel plastic catheter having two openings, one made at the end of the catheter, the other near, on the side.

With the help of a known aspirator, only separate nasal aspiration can be carried out, which consists in the alternate rehabilitation of one of the halves of the nose and pharynx.

The disadvantage of separate sequential aspiration of the contents from one half of the nose and separately from the pharyngeal cavity is the significant likelihood of blood and saliva entering the airways, which leads to complications in the postoperative period (up to 20%). Complications are associated with the entry of blood, saliva and gastric contents into the respiratory tract, which leads to the development of severe aspiration pneumonia.

This technical solution is aimed at reducing postoperative complications during short operations on the nasal cavity and pharynx under intravenous anesthesia without endotracheal intubation.

The novelty of the claimed aspirator is the presence of three catheters, the suction channels of which are connected by a three-channel connector for connection to a vacuum device. Moreover, each of the catheters is equipped with perforations in the form of holes of different sizes, decreasing in the proximal direction. To reduce mucosal trauma

the best sheaths are catheters made of thermoplastic material, the density of which decreases at body temperature.

A new technical result that can be achieved by the invention consists in the simultaneous evacuation of contents from both halves of the nasal cavity and pharynx.

The utility model is illustrated by drawings, in which Fig. 1 shows an aspirator for operations on the nasal cavity and pharynx under intravenous anesthesia without intubation of the trachea, and Fig. 2 shows its perforated part.

The aspirator contains two nasal catheters 1, a pharyngeal catheter 2 connected by a connector 3 connected to a vacuum. Each of the catheters has a perforated part 4. The horizontal position of the channels is most convenient for surgical intervention. Preferred to use are atraumatic thermoplastic catheters with perforations of 7 cm at the distal end of the catheters, increasing their diameter from the proximal to the distal direction. The location of the third catheter in the larynxopharynx cavity and a constant aspiration regimen exclude blood from entering the respiratory tract.

The optimal length of the aspiration catheters - 50 cm and a diameter of 5 mm allows you to freely manipulate the nasal cavity and pharynx, without limiting the actions of the surgeon.

The aspirator is implemented in a permanent three-channel aspiration, performed as follows. After the patient is anesthetized, an aspirator is introduced into each half of the nose and pharynx, the vacuum device of which is brought into operation before the introduction of the aspirator into the nasal cavity and pharynx.

Due to the perforation of the catheters, all fluid is constantly aspirated from the nasal cavity and pharynx, without interfering with the manipulation of the surgeon.

Example. Patient W, 25 years old. Complaints about the deformation of the external nose after an injury in everyday life, a violation of nasal breathing. On the x-ray of the nasal bones - a fracture of the nasal bones with a shift.

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

Preparation for the operation is traditional. Under intravenous anesthesia, an aspirator with a diameter of 5 mm was installed in both halves of the nose and larynx. With constant aspiration, reposition and anterior tamponade were performed. Tampons are removed after 5 days. No complications were noted. Using the claimed aspirator, 39 patients were operated on; no complications were observed.
