Force measuring device for surgical operations is created by a mechanical part (1) and a measuring unit (2). The mechanical part (1) consists of a segment (4) with a measuring element (6), a pressure ring (5), a fixing plate (8) with screws and a connecting stone (7). The mechanical part (1) is inserted between the operating hook (3) and the handle with the eyelet (9). The segment (4) with the measuring element (6) is fixed to the operating hook (3) on one side by the pressure ring (5) with the screw and on the second side is attached to the segment (4) with the measuring element (6) attached handle with the eyelet (6) using a connecting stone (7). The position of the measuring member (6) in the segment (4) is fixed by a fixing plate (8) with screws and a connecting stone (7). The signal from the measuring member (6) is guided by a conductor passing through the connecting stone (7) to the measuring unit (2). The device according to the invention can be used in medicine during the operation of surgical interventions, in particular in the abdominal and respiratory tract. at all interventions that require the use of retractors in order to keep them open.
