Surgical grasper instruments

Surgical grasper instrument comprising: a body 2; fixed grip 4 and movable actuation grip 16; an actuation shaft 6; and first and second opposed jaws [8, 10, figure 1] at the distal end of the actuation shaft 6. The actuation grip is arranged to move the actuation shaft with respect to the body such that the first jaw is rotatable with respect to the second jaw, between open and closed positions. The instrument is provided with an actuation indicator for providing an indication to a user of the device of a position of the actuation grip corresponding to an intermediate position of the first and second jaws, the intermediate position being between the open and closed positions. The actuation indicator may comprise a first engagement element defining a series of teeth 34 extending from the actuation grip, and second engagement element 40 having portion 42 which may be biased by means 44 to engage with the teeth 34. The shaft may include a measurement scale 54 or visual indicator corresponding to jaw position. This allows a user to determine jaw position when they cannot be viewed.
