the group elettrochirurgico trocar, so-called 'trocar' with bipolar electrodes.

摘要

a group trocar, so-called "trocar", includes a device "trocar and cannula" stretched around it.the device incorporates a "trocar" element elettrochirurgico incisor, which is used to drill a hole of guide for the tube.it therefore allows the rest of the group "trocar" to enlarge the puncture. the element includes a bipolar electrode teeth group.an electronic control circuit detects the passage of the current to the element edge and, when the device "trocar" penetrates the wall of the body cavity is etched.this circuit interrupts the connection to the associated generator elettrochirurgico.another set of control circuits to prevent that a surgeon can resume the execution of the action elettrochirurgico until after a fixed period of time.for multiple "trocar" of different diameters for the same group.
