Endoscopic instrument

An endoscopic instrument, comprising:

• a first shaft;
• a second shaft pivotably connected to a proximal end of the first shaft via a proximal main hinge having a socket part and a ball part;
• a third shaft pivotably connected to a distal end of the first shaft via a distal main hinge having a socket part and a ball part;
• a main pressure rod coupled between the ball part of the proximal main hinge and the ball part of the distal main hinge, such that displacement of the proximal main hinge by angling the second shaft relative to the first shaft transmits a force, via the main pressure rod, to the distal main hinge and causes there an angling of the third shaft relative to the first shaft;
• a fourth shaft pivotably connected to a proximal end of the second shaft via a proximal lateral hinge having a socket part and a ball part;
• a fifth shaft pivotably connected to a distal end of the third shaft via a distal lateral hinge having a socket part and a ball part;
• a proximal inner hinge arranged in an interior of the ball part of the proximal main hinge, the proximal inner hinge pivotable relative to the ball part of the proximal main hinge;
• a distal inner hinge arranged in an interior of the ball part of the distal main hinge, the distal inner hinge pivotable relative to the ball part of the distal main hinge;
• a proximal lateral pressure rod coupled between the proximal inner hinge and the proximal lateral hinge;
• a secondary pressure rod coupled between the proximal inner hinge and the distal inner hinge;
• a distal lateral pressure rod coupled between the distal inner hinge and the distal lateral hinge;
• wherein displacement of the proximal lateral hinge by angling the fourth shaft relative to the second shaft transmits a force to the proximal inner hinge via the proximal lateral pressure rod, which in turn transmits the force to the distal inner hinge via the secondary pressure rod, which in turn transmits the force to the distal lateral hinge via the distal lateral pressure rod, which thereby causes there an angling of the fifth shaft relative to the third shaft.
