Abstract
The device of the invention consists of a plurality of tubular cannulae, which prior to the surgery, are linked together at their distal ends by flexible elements, such as wires or threads. All the threads, the number of which is one less than the number of the used cannulae, are passed through one of the cannulae and the distal ends of the threads are either attached to the walls of other cannulae, at their distal ends, or pulled back through one of the cannula forming the loop at the distal end and fixed at the proximal end of the cannula. During surgery, the cannulae with their distal ends being linked are inserted into the patient's body through an incision and then the cannulae are used for guiding various surgical tools. Due to flexible linking of the cannulae at their distal ends, the cannulae can be easily manipulated without disconnection and without a need for use extraneous X-raying for reorientation of the cannulae.
