Trocars are used for minimally invasive endoscopic surgery. The trocars are used to create access to the intracorporeal surgical field. The trocar has a trocar mandrel, also known as an obturator. The trocar mandrel has a distal tip used for penetrating the tissue. On the trocar mandrel the trocar sleeve, which is punched through the tissue along with the trocar mandrel. As soon as the trocar tip has reached the surgical field, the trocar mandrel is withdrawn, whale the trocar sleeve remains as access for the surgery. At the proximal end of the trocar is a valve block, which especially serves for closing off the trocar sleeve following withdrawal of the trocar mandrel to prevent escape of an insufflation gas and to allow sealed introduction of an instrument, an endoscope or the like through the trocar sleeve.
