Claim Text:
1. An endoscopic instrument, comprising: a control section having a control element; an instrument shaft having an actuatable portion, wherein the instrument shaft is connected to the control section; an adjustment element; a pull element, which is mechanically coupled to the adjustment element and to the actuatable portion of the instrument shaft, such that a movement of the adjustment element can cause an actuation of the actuatable portion via a force transmission via the pull element; an actuator, which is coupled to the adjustment element, such that an actuation of the actuator can cause a movement of the adjustment element by force transmission from the actuator to the adjustment element; and an intermediate element, which is operatively connected to the control element and to the adjustment element such that a force F applied to the control element by a user can be transmitted to the adjustment element via the intermediate element in order to move the adjustment element; wherein the intermediate element has a first portion and a second portion, the first portion is connected to the second portion, the second portion having a greater bending resistance than the first portion, and the first portion having a measurement element configured to measure a flexion of the first portion; wherein the adjustment element has a first abutment device, which defines a first movement range of the first portion relative to the adjustment element, and a second abutment device, which defines a second movement range of the second portion relative to the adjustment element, wherein the first movement range is smaller than the second movement range; and wherein the first portion is configured to contact the first abutment device.
