MEDICAL DEVICES INSTALLATION AND MONITOR CONFIGURATION IN A NEW OPERATING ROOM

With the advancement of technological innovations, surgical techniques and clinical needs, the need for a structural and functional modernization of operating spaces is becoming increasingly evident. Surgical rooms must now be rethought as intelligent, dynamic, integrated environments ready to welcome the challenges of modern medicine. Today, thanks to rapid technological progress, video systems have become fundamental tools for real-time collaboration between medical teams, both within the same healthcare facility and remotely, with specialists connected from other locations or countries, thus creating video-integrated or hybrid rooms. The aim of this work is to describe the procedures for setting up an angiographic operating room, in particular the installation and configuration of three medical wall units, a surgical lamp and a monitor capable of interfacing with hybrid operating rooms. The latter allows the recording of surgical procedures, the control of various vital parameters and/or diagnostic images taken on a single screen, but also of the various devices in the room (surgical lamps, surgical cameras, etc.) in addition to the advanced teleconference function that allows connection and consultation with colleagues and operators in other rooms of the hospital or even in other facilities. The type of wall unit adopted guarantees a new practical solution that allows for having a power source, the possibility of supplying medical gases and a data transmission cable in a single device. The lighting of the implanted surgical lamp adopts an intelligent self-regulation system that allows for adequate intensity without having to continually move the device. The entire assembly operation required a long and careful preliminary planning phase. Measurements of the operating room were taken and simulations were made on the future arrangement of the elements within the environment to avoid collisions and provide greater comfort during the carrying out of the surgical procedures. The wall units were fixed to the ceiling with steel plates connected by threaded rods to counterplates on the floor of the slab. The various configuration options for the monitor examined were also described. The design tensile strength of the bolt was measured at 141 kN (for the pendant with monitor) and 110 kN (for the surgical light) while the puncture resistance of the steel plate connected to the structure was determined to be respectively 244 kN and 219 kN. For the comparison with the threshold values (rispectively 11,85 kN for the large screen pendant and 17.89 kN for the surgical lamp) the lowest values were chosen. The shear resistance of the bolt was measured at 94 kN and 73 kN respectively for the large screen pendant and for the surgical light while the hole bearing resistance at 179 kN and 194 kN indicating acceptable compliance with respect to the threshold values (0.508 kN and 0.507 kN). The combined verification of the shear and tensile resistance produced a value of 0.07 and another one of 0.13, which are significantly lower than 1 which ensures that the connection is verified. The installation allowed also a reduction of the total number of cables inside the operating room by a factor of 4, ensuring greater freedom of movement and consequent greater safety and comfort for the operators. The signal delay achieved by the monitor is 50 ns, 800,000 times less than the ability of the human eye to detect time delays, significantly distinguishing itself from commercial monitors still in use in many hospitals. The structural calculations performed following the main directives have guaranteed adequate safety checks, therefore the installed devices will guarantee greater performance, adequate safety, comfort and greater control in the operating environment.
