This disclosure relates to a probing instrument (100) that includes an outer tubular shaft (102) having an associated proximal end (102A) and a distal end (102B), an inner tubular shaft (104) having an associated proximal end (104A) and a distal end (104B). The inner tubular shaft (104) is configured to be positioned and move inside the outer tubular shaft (102). The probing instrument (100) may include a probing assembly including an end effector unit (106) positioned at the distal end (104B) of the inner tubular shaft (104) and a manipulating unit (108) coupled to the end effector unit (106). The manipulating unit (108) may include an input device (110) positioned at the proximal end (104A) of the inner tubular shaft (104). The manipulating unit (108) is configured to reconfigure the end effector unit (106), in response to the input device (110) receiving an intervention from a user.
