摘要：
The utility model relates to surgical instruments, in particular, used to remove tissue from cavity formations and can be used in surgical departments. A tissue removal device containing a trocar into which a stylet is inserted； a gearbox consisting of a housing, holders and an axis, the end of which has a hexagonal shape and is used to connect to an electric motor； the axis passes through the holders between which a gear is located, characterized in that the distal part of the stylet has an external thread corresponding to the internal thread of the head located in its proximal part； the working part of the cylinder head has a cutting edge； between the distal and proximal parts of the stylet there is a gear, the module of which corresponds to the gear module of the gearbox； the proximal part of the stylet has a double bearing, the outer diameter of which corresponds to the inner diameter of the gear housing； the bearing has a channel into which a fitting having an outer diameter of 8 mm is pressed in； the distal part of the trocar has a window opening in its lumen and an atraumatic end； in the middle and proximal part of the trocar there are sliding bearings, the inner diameter of which corresponds to the outer diameter of the stylet； the proximal end of the trocar has an external thread corresponding to the internal thread of the distal part of the gear housing； the gearbox housing has an internal channel into which the proximal end of the stylet is inserted with the gear and gears combined； the proximal part of the gearbox has a solenoid, which abuts against the stylet gear.Полезная модель относится к хирургическим инструментам, в частности, применяемым для удаления тканей из полостных образований и может быть использована в хирургических отделениях.Устройство для удаления тканей, содержащее троакар, в который вставлен стилет； редуктор, состоящий из корпуса, держателей и оси, конец которой имеет шестигранную форму и служит для соединения с электромотором； ось про
