Abstract
A multiportal device for percutaneous surgery consists of a guiding device with a radial arm that supports an auxiliary guiding device, which can slide along the arm and can be fixed in a require angular position on the arm. The device also includes a first cannula, which can be inserted into the patient's body through the guiding device and can be fixed in a required axial position, and a second cannula, which can be inserted into the second guiding unit and fixed therein. The arch-shaped form of the arm ensures intersection of distal ends of both cannulae in one point aimed at the symptomatic site where surgery has to be done. The device is provided with a linking mechanism that links the distal ends of both cannulae in their position inside the body of a patient. In the engaged state of the linking device, the cannulae still have some freedom of relative movements that may be required for manipulation with cannulae during the surgery. The invention also relates to a method of using the multiportal device for percutaneous surgery. The device allows insertion of a plurality of cannulae and permanently maintaining them in controlled positions without resorting to additional X-ray.
