摘要：
The invention relates to the field of medicine, and more particularly to otorhinolaryngology. The purpose of the utility model is to increase the ease of use of the needle and the safety of its use during the puncture of the maxillary sinus. This object is achieved in that the working part of the needle consists of a core length of 60 mm, the cross section of 4 mm diameter and stitching portion 10 mm long, 2 mm diameter cross-section the difference in diameters and body pricking needle of 2 mm generates limiter which prevents too deep penetration of the needle into the maxillary sinus and traumatization of the rear wall of the maxillary sinus the main part of the needle has a grading scale interval of 5 mm, allowing it to control the depth of insertion and reduce the risk of injury of the orbit and the structures of the nasal cavity Universal needle cannula allows you to attach to it a disposable plastic syringe the needle is a disposable product, the cannula and the flat palm of the fingers are made of plastic. The appearance of the possibility of joining plastic disposable syringe will allow to more accurately determine the number of abnormal contents of the maxillary sinus to make fence contents dosing administered antiseptic solutions availability of calibration allows you to control the depth of needle insertion and reduce the risk of injury and orbital structures of the nasal cavity presence restrictor creates obstacle excessively deep penetration of the needle into the maxillary sinus and reduce the risk of traumatization of the rear wall of the maxillary sinus disposable products will improve asepsis and avoid the need for periodic sharpening of the needle. The needle is bent at an angle of 10 ° with the tubular needle cannula and an abutment for the fingers. The total length of the product 120 mm, length of the working portion 70 mm, the working part of the needle comprises a main portion and stitching. The length of the needle stitching 10 mm, the main par
