A pharynx protector may include a proximal end and a distal end, the distal end being adapted to be inserted into an oesophagus of a patient. The protector may include an elongated tubular part and a distally located receiving portion for receiving a puncture needle during a laryngectomy, wherein the tubular part is substantially flexible. The receiving portion may include a first opening, communicating with a lumen of the tubular part, such that a guide wire may be inserted through the first opening and further passed proximally out of the pharynx protector. A surface of an inner wall may be of a rigid material. |
