A novel 3D camera system with control unit was tested, which can be connected to all common 2D optics and enables real-time 3D visualization with a high depth of field.  Additionally, the 3D-KS was evaluated for its ability to provide 3D visualization after connecting disposable instruments (cystoscopes and ureterorenoscopes) via SDI/HDMI. Color and grayscale fidelity, color deviation, depth of field, and moiré effect were measured for each optic in both the 2D image and the 3D image generated by the 3D-KS. For the disposable instruments, the 3D image was generated solely by the control unit.

The accuracy of diagnostic and therapeutic endoscopic procedures depends on the optical and imaging quality of the endoscopic equipments. Furthermore, the use of 3D optics for spatial visualization and improvement of surgical options in laparoscopy has become established.  Special optics and camera units are normally required for 3D endoscopy systems. This study aims to determine whether it is possible to utilize 2D optics for 3D applications with the aid of a novel 3D camera system with control unit (3D-KS).

The generated 3D images were impressive, exhibiting good color saturation, high contrast, and good resolution with a flicker-free image frequency of 60 Hz for all optics, including the disposable instruments. The 3D image generated with the 2D optics appeared vivid and precise with good depth of field. Comparative exercises (suturing, grasping, and foreign body removal) demonstrated the advantage of the 3D image over the 2D image during exercises on the model (laparoscopy trainer and urogenital tract intervention trainer (UTIT).

3D optics significantly improve surgical work.

The innovative 3D camera system with control unit used with 2D optics and disposable instruments is compelling due to the optional and simple implementation of a 3D visualisation. This can be used in practice using existing instruments and with minimal costs.
