The present invention relates to a laparoscopic medical instrument holding device used for supporting surgeries and surgical procedures. The laparoscopic medical instrument (1) holding device has a platform (6) with a holder (3) for securing the instrument (1). The holder (3) has a form of at least two clamping claws arranged on the platform at a distance from each other and each of the clamping claws comprises a two-arm base (3.2) and to each arm of said base there is a movably mounted arm of the claw (3.1), wherein each arm of the claw (3.1) has at least two guide rolls (3.3). Moreover, the arm of the claw (3.1) has a footing (3.6) from ferromagnetic material located above a magnet (6.10) mounted on the platform (6), wherein in order to adjust the holding force between the footing (3.6) and the magnet (6.10) the footing (3.6) is slidably mounted on the arm of the claw (3.1) while maintaining the constant distance from the magnet (6.10) and the magnet (6.10) is slidably mounted on the platform (6) with the possibility to adjust the distance between said magnet (6.10) and the footing (3.6). In the holder (3) there is a releasably mounted instrument sleeve (2) for securing the laparoscopic instrument (1) and sain instrument sleeve (2) has inside a pair of clamping elements (2.5) and a mounted outside securing nut (2.7) coupled via a deflecting transmission (4) to a motor unit (5) attached to the platform (6). On the outside circumference of the instrument sleeve (2) or on the outside circumference of the securing nut (2.7) there is at least one groove (2.2, 2.8) for the guide rolls (3.3).
