Description

The utility model refers to the field of medicine, and more specifically to otorhinolaryngology, m is intended to perform diagnostic and therapeutic puncture of the maxillary sinus through the lower nasal passage.

Puncture of the paranasal sinuses for both diagnostic and therapeutic purposes has been widely used in practice. As a diagnostic procedure, a puncture allows you to determine the presence of exudate or liquid blood in the sinus, suspect a soft tissue formation in the sinus lumen, and also a contrast agent of the day of contrasting sinusography can be introduced into the sinus. As a medical procedure, puncture provides for the evacuation of inflammatory exudate and sinus lavage with drug solutions.

Known direct needle for spinal puncture, which can be used for puncture of the maxillary sinus. The product is a curved tubular needle with a cannula and mandrin. Product length: 60, 90, 120 mm. The product is intended for single use. The needle and mandrin are made of stainless steel, the cannula is made of plastic. The diameter of the needle cross-section is 1-1.2 mm, the bevel angle of its end is 45 °. On the working surface of the needle there is a graduation at a division price of 10 mm, the mandrin has a taper angle equal to the taper angle of the working end of the needle tube. The cannula has a conical hole for connection of the type "Luer" [1].

The disadvantage of this needle is the insufficient thickness of the needle wall, which can lead to its deformation when applying and traumatizing the internal structures of the nasal cavity, as well as the small diameter of the needle does not always ensure an adequate outflow of pathological contents from the maxillary sinus.

Known needle type "Kulikovsky", which is a pointed tube with a curved tip at an angle of 10 ° and a cannula. Product length 85 mm. The product is intended for single use. The needle and mandrin are made of stainless steel, the cannula is made of plastic. The diameter of the cross section of the needle is 2 mm, the bevel angle of its end is 45 °. The cannula has a conical hole, equipped with a plastic adapter for attaching a disposable plastic syringe [3].

The disadvantages of this device are the lack of a cannula for attaching a non-standard syringe (Jeanne type) through a rubber tube-conductor to rinse the maxillary sinus; the lack of graduation does not allow controlling the depth of insertion into the nasal cavity and maxillary sinus, which creates a risk of injury to the orbit and structures of the nasal cavity.

The Kulikovsky needle is known, which is a tubular needle bent at an angle of 10 ° with a cannula with a total length of 120 mm and a length of the working part of 70 mm. The product is intended for reusable use. The needle and cannula are made of stainless steel. The diameter of the cross section of the needle is 2 mm, the bevel angle of its end is 45 °. At the opposite end there is a steel flat palm rest and a steel cannula for attaching a non-standard Jeanne type syringe through a rubber conduit for flushing the maxillary sinus [2].

The disadvantages of this device are the need for sterilization after use, which requires additional equipment, increases the risk of the spread of infectious diseases; the needle adapter does not allow you to attach a disposable syringe that allows you to accurately determine the amount of pathological contents of the maxillary sinus and to dose the injected antiseptic solutions when performing medical procedures; the lack of graduation does not allow controlling the depth of insertion into the nasal cavity and maxillary sinus, which creates a risk of injury to the orbit and structures of the nasal cavity; the material from which the needle is made requires periodic sharpening, which creates difficulties in its operation.

This device is taken as a prototype of the proposed needle for puncture of the maxillary sinus.

The purpose of creating a utility model is to increase the usability of the needle and the safety of its use during puncture of the maxillary sinus.

This goal is achieved in that the working part of the needle consists of a main part 60 mm long, a cross-sectional diameter of 4 mm and a piercing part 10 mm long, a cross-sectional diameter of 2 mm; a difference in the diameters of the stitching and the main part of the needle of 2 mm forms a stopper that prevents the needle from penetrating excessively deep into the maxillary sinus and traumatizing the posterior wall of the maxillary sinus; on the main part of the needle there is a graduation at a division price of 5 mm, which allows you to control the depth of its introduction and reduce the risk of injury to the orbit and structures of the nasal cavity; The universal needle cannula allows you to attach a disposable plastic syringe to it; the needle is a disposable product, the cannula and the flat palm rest are made of plastic.

The emergence of the possibility of attaching a disposable plastic syringe will allow you to more accurately determine the amount of pathological contents of the maxillary sinus, extract the contents, dose the injected antiseptic solutions; the presence of graduation will allow you to control the depth of the needle and reduce the risk of injury to the orbit and structures of the nasal cavity; the presence of a limiter will create an obstacle to excessively deep penetration of the needle into the maxillary sinus and reduce the risk of trauma to the posterior wall of the maxillary sinus; the disposability of the product will improve aseptic, as well as avoid the need for periodic sharpening of the needle.

The needle is a tubular needle bent at an angle of 10 ° with a cannula and an emphasis for fingers. The total length of the product is 120 mm, the length of the working part is 70 mm, and the working part of the needle consists of the main part and the stitching. The length of the stitching part of the needle is 10 mm, the main part is 60 mm. The working part of the needle is equipped with a limiter formed by a difference in diameters of 2 mm of the piercing and the main part of the needle. The diameter of the cross section of the main part of the needle is 4 mm, the stitching part is 2 mm, the bevel angle of the end of the stitching part is 45 °. On the main part of the needle there is a graduation with a graduation price of 5 mm. At the opposite end there is a flat palm rest and cannula for attaching a disposable plastic syringe. The outer surface of the cannula is ribbed and designed to connect the rubber tube of the conductor to use a non-standard syringe like Jeanne. The product is intended for single use. The working part of the needle is made of stainless steel, the cannula and the palm rest are made of plastic.

The utility model is illustrated by the graphic material in FIG. 1 shows a proposed needle, side view.

The proposed product consists of the working part (1) of the cannula (2) and a flat palm rest (3). The working part of the needle (1) consists of the main part (4) and the pricking (5). The working part of the needle (1) is equipped with a limiter (6) formed by the difference in the diameters of the pricking (5) and the main (4) part of the needle. On the main part of the needle (4) there is a graduation (7) with a division price of 5 mm.

Comparison of the proposed needle with others known in the field of medicine, showed its compliance with the criteria of a utility model.

The needle is used as follows. After local application anesthesia, the needle is inserted under the lower nasal concha into the lower nasal passage, and being guided by graduation on the needle, 1.5-2 cm from the front edge of the lower nasal concha, a puncture is made to the stop in the direction of the outer edge of the corresponding eye. If it is necessary to rinse or aspirate the contents of the maxillary sinus, a disposable plastic syringe or rubber conduit is attached to the cannula, followed by the attachment of a non-standard Jeanne type syringe.

Using the proposed needle for puncture of the maxillary sinus can improve the convenience and safety of its use by increasing the control of the technique of manipulation, reducing trauma to the structures of the nasal cavity, expanding diagnostic and therapeutic options, due to the universal cannula and improving asepsis due to the single use of the instrument.

A needle for puncture of the maxillary sinus is possible and appropriate to use in the ENT departments of medical organizations.
