The invention relates to medicine, namely to the endosurgery, and a surgical instrument, which cannula with stylet provides entry into the cavity, and without stylet - conducting diagnostic endoscopy and execution of operational activities at the maxillary sinus, but it is applicable in other types of surgery. This utility model can significantly improve the efficiency of the design of the trocar. To this end, the trocar comprising a cannula and stylet, the cannula is made of two parts having a transition which prevents burial of the cannula into the cavity, wherein the proximal tapered portion of the cannula is provided with lugs supplied with risks, and the distal cylindrical portion of the cannula is provided with a side window tool for introducing and removing pathological formations under the control of, the side window is arranged perpendicular lugs axis, the cylindrical portion has at the end a locking prong and aligned to the inside diameter a stylet having a knife blade, the stylet trocar blade is formed by four plane faces and they are located in pairs of faces crossing lines having a common intersection point at the tip of the blade, wherein the angle between the faces of the blade of each pair is made sharp and with the possibility of cutting the bone, and the angle between the lines of intersection of each pair of faces and made blunt with the possibility of moving apart the soft tissue, wherein at the lateral sides of the stylet arranged and configured more flat faces to facilitate penetration through the bone wall into the lumen of the maxillary sinus.1 n.p.f., 1 fig.Полезная модель относится к медицине, а именно к эндохирургии, и является хирургическим инструментом, канюля которого со стилетом обеспечивают вхождение в полость, а без стилета - проведение диагностической эндоскопии и выполнение операционных действий на верхнечелюстной пазухе, но оно применимо и в других видах оперативного вмешательства.
