摘要：
The invention relates to the field of medical technology. In particular a special surgical instruments reusable. The apparatus may be used in oncology for the treatment of brain tumors. The essence is that the device is an implantable system consisting of a special design of the port, thromboresistance catheter. The outer part of the port in the side of the projection has a spherical shape in order to avoid tissue necrosis of the port. Port membrane inclination angle is 30 ° in order to avoid the inflection of the optical fiber introduced through the wide straight Huber needle. The camera port is made of titanium, is smooth, has the shape of a miter, a smooth transition to the outlet port with the nozzle. This form will allow the optical fiber to pass without hindrance from the port in the catheter and reach necessary for photodynamic therapy area. The catheter is made of a polymer with a thromboresistant coating. The inner diameter of the catheter is 2.2 mm, the outer - 2.7 mm. For convenience, the catheter in its lumen is a nitinol wire, 2.2 mm in diameter. On the outer wall of the catheter there centimeter marks that allow both to specify the length of the catheter from its distal end to the junction with the port, and for determining the depth of insertion of the optical fiber with a diffuser. Inside the catheter is a nitinol wire for the convenience of its introduction into a trocar or promotion of the resected tumor bed subcutaneously. The use of utility model improves the results of treatment of brain tumors and the opportunity to conduct mnogokursovoy photodynamic therapy.Полезная модель относится к области медицинской техники. В частности к специальным хирургическим инструментам многоразового использования. Устройство может быть использовано в онкологии для лечения опухолей головного мозга. Сущность заключается в том, что устройство представляет собой имплантируемую систему, состоящую из особой конструкции порта, тромборезистентного катетера. Наружная часть
