1. A tethered laparoscopic probe for deployment through a trocar into a cavity of a subject, the tethered laparoscopic probe configured to be manipulated by fenestrated laparoscopic graspers comprising opposing fenestrated jaws, the tethered laparoscopic probe comprising:
a probe head shaped for insertion through the trocar, the probe head comprising:
an elongated casing;
a sensor arranged within the casing, the sensor defining a sensing direction of the probe head; and
a grip for secure grasping by the fenestrated laparoscopic graspers, the grip comprising a pair of protrusions for mating with the fenestrated jaws of the fenestrated laparoscopic graspers, wherein a first protrusion of the pair of protrusions is graspable by a first jaw of the fenestrated laparoscopic graspers while a second protrusion of the pair of protrusions is graspable by a second jaw of the fenestrated laparoscopic graspers; and
a tether coupled to the probe head and for, in use, tethering the probe head through the trocar;
wherein the pair of protrusions are positioned and shaped to enable the grip to be grasped securely by the fenestrated laparoscopic graspers at a first angle relative to the sensing direction of the probe head so as to restrict the fenestrated laparoscopic graspers from rotating about the protrusions; and
wherein the pair of protrusions are positioned and shaped to enable the grip to be grasped securely by the fenestrated laparoscopic graspers at a second angle relative to the sensing direction of the probe head so as to restrict the fenestrated laparoscopic graspers from rotating about the protrusions, the second angle different to the first angle.
