Abstract: A forceps construction includes a forceps frame having a distal end, the distal end including a first extension and a second extension, the first extension and the second extension extending in distal direction from a main part of the forceps frame, a first jaw element rotatably mounted on the first extension, a second jaw element rotatably mounted on the second extension, an actuation assembly connected to the first jaw element and the second jaw element to rotate the first jaw element and the second jaw element with respect to the forceps frame. A surgical instrument, for example a surgical instrument for minimally invasive surgery, includes a frame and a jaw element.

Abstract: The invention provides surgical instrument, for example surgical instrument for minimally invasive surgery, comprising: an elongate frame, at least one jaw element mounted movably at a distal end of the elongate frame, a trigger device to operate the at least one jaw element and arranged at a proximal end of the elongate frame, an actuation rod provided between the trigger device and the at least one jaw element to transfer movement of the trigger device to the at least one jaw element, a sensor to provide a sensor signal representative for a force exerted on the at least one jaw element, and a tactile feedback device to provide tactile feedback to the user on the basis of the sensor signal, wherein the tactile feedback device is mounted on the elongate frame.

Abstract: A surgical instrument for the use in minimally invasive surgery includes a distal part having an elongated shaft, at least one working element and an actuation rod. The at least one working element is movably mounted on a distal end of the shaft and a first end of the actuation rod is connected to the at least one working element. The instrument further includes a proximal part having an actuator device releasably connected to a second end of the actuation rod. The actuator device is configured to move the at least one working element with respect to the shaft by movement of the actuation rod. A sensor is arranged in the actuator device to measure force and/or strain exerted on the actuator device and to thereby transmit a signal that is representative for the force exerted on the at least one working element.

Abstract: The invention relates to an instrument for surgery, in particular minimally invasive surgery. The instrument includes means for feeding back a force which is exerted on the working element of the instrument to the operating element. These means include at least a first force sensor for measuring the force which is exerted on the working element, a control unit and a first actuator. On the basis of a signal which originates from the first force sensor, the control unit controls at least the first actuator in order to control the operating element. Furthermore, the means preferably include a first position sensor for measuring a position of the working element with respect to the frame. The control unit advantageously determines an impedance which the working element is subject to as a result of the presence of a tissue or the like, on the basis of which impedance the control unit controls at least the first actuator.
