The cannula of this trocar has a proximal coniform portion and a distal cylindrical part with a lateral aperture and a fixing tip. Such design ensures perfect sanation of the maxillary sinus. The instrument has three stylets one of which (non-traumatic) makes possible the approach to the canine fossa and two others (having concave edges and shaping knife-like blades) to the maxillary sinus. These two stylets are used to gently cut the anterior wall of the sinus and obtain osteo-periosteal fragments in the form of three lobes. Maxillary microsinusotomy being completed, the lobes become spontaneously apposed which leads to rapid healing and formation of a soft scar along the section line as well as to complete restoration of the anterior wall of the maxillary sinus. Cannulas of two different diameters are available that enable the instrument to be used for the treatment of adults and children. https://www.researchgate.net/publication/23803950_Clinical_a... Trocar A trocar (or trochar) is a medical or veterinary device used in minimally invasive surgery, typically made up of an awl (which may be a metal or plastic with a pointed or tapered tip), a cannula (essentially a rigid hollow tube) and often a seal,[1][2] and some trocars also include a valve mechanism to allow for insufflation. Trocars are designed for placement through the chest and abdominal walls during thoracoscopic and laparoscopic surgery, and each trocar functions as a portal for the subsequent insertion of other endoscopic instruments such as grasper, scissors, stapler, electrocautery, suction tip, etc. — hence the more commonly used colloquial jargon "port". Trocars also allow passive evacuation of excess gas or fluid from organs within the body. https://en.wikipedia.org/wiki/Trocar Троакар Троака́р (фр. trocart; происходит от словосочетания trois — «три» и carre — «ребро», «грань», которое впоследствии стало писаться trois-quart под влиянием омофонии между словами carre и quart во французском языке[1][2]) — хирургический инструмент, предназначенный для проникновения в полости человеческого организма через покровные ткани с сохранением их герметичности в ходе манипуляций. Классический троакар представляет собой полую трубку, в которую вставляются специальные стилеты, снабженные рукояткой[3]. https://ru.wikipedia.org/wiki/Троакар |
