The abrasive head () comprises one or more abrasive elements (), each abrasive element connected to a respective flexible shaft (). The one or more guiding tracks () are arranged such that distal movement of the one or more flexible shafts () causes the abrasive head () to move from a radially contracted configuration to a radially expanded configuration.
