Sapienza University of Rome holds study to evaluate the Sony HMS-3000MT 3D medical head mount display

The evaluation study took place as part of the Master’s Course in Technological Innovations in Advanced Laparoscopic Surgery, at the Institute of Orthopaedic Trauma Surgery (ICOT), Rome.

Sapienza University of Rome holds study to evaluate the Sony HMS-3000MT 3D medical head mount display

Background:

The Master’s Course in Technological Innovations in Advanced Laparoscopic Surgery from the Sapienza University of Rome is focused on teaching the most recent technological innovations in laparoscopic and endoscopic surgery. The course participants are all urologists with experience in laparoscopic and endoscopic surgery, who attend surgical operations at the Complex Operative Unit of Urology at the Pontino Centre. As part of the course, a study was launched to evaluate the Sony HMS-3000MT 3D medical head mount display system, involving 12 of the course participants. All operative procedures were carried out with the assistance of Sony's 3D technology and the HMS-3000MT system.

The challenge:

Laparoscopic surgery is widely used for the treatment of cancer and many other diseases. The precise identification of dissection planes and anatomical structures, as well as the magnification of certain anatomical details, is crucial. The availability of advanced image viewing systems therefore plays a fundamental role in surgery, in order to optimise the safety and success of operations. In recent years, attention has been focused on improving the comfort of the surgeons themselves. Traditional video systems impose physical disadvantages upon surgeons, requiring them to alternate their view between their equipment and a separate monitor. Consequently, in lengthy and demanding procedures, premature fatigue may affect the safety of the surgical procedure.

The solution:

3D HD viewing in laparoscopy can contribute significantly to recognising dissection planes and anatomical structures by providing surgeons with greater visual clarity and effective ergonomic support. The Sony HMS-3000MT device is a personal viewing system that allows surgeons to view images from 3D and 2D colour surgical camera systems. The system consists of the HMI-3000MT image processor unit, which receives the video image from the surgical camera, processes it, and sends it to the HMM-3000MT head mount monitor that provides stereoscopic visualisation.

The head mount monitor is adjustable for increased comfort during extended wear, and also allows a ‘look down’ view of the operating site for the surgeon. Unlike passive (circular polarised) 3D systems, the dual-panel design uses two independent OLED panels to display separate images for the wearer’s left and right eye. This makes it possible to obtain smooth, natural stereoscopic images, free of ´ghosting´ and crosstalk.

The HMI-3000MT image processor unit accepts video input signals in many common 3D and 2D formats from surgical camera systems. Video images can be flipped or rotated for a more convenient viewpoint and can also be output for viewing on an external 3D monitor. A second head mounted monitor can be connected to the image processor unit, allowing a second user to view the images simultaneously.

The result:

On days when a large number of surgical procedures are taking place, a system such as the HMS-3000MT provides significant advantages in terms of reducing muscular fatigue and eye strain according to the feedback from surgeons so far. The HMS-3000MT is a product specifically designed to minimize physical exertion, improve posture and help to reduce eye movement from monitor to patient. It also offers high quality 3D viewing which represents a huge advance in terms of depth of surgical field, manoeuvrability, image detail and suture times.

"This system allows you to dramatically improve the surgeon's posture during surgical procedures, making operations easier for the entire surgical team. The 3D visual optimisation is significant in both endoscopic and laparoscopic surgery" commented Professor Antonio Carbone, Director of the Complex Operative Unit, Urology, Sapienza University of Rome.

“The advantages of this system, in terms of diagnostic potential, are excellent. The HMS-3000MT, which uses OLED technology, offers the ability to recognise really exceptional dissection plans, allowing you to obtain excellent results, especially during operations that aim to accurately remove cancerous tumours without damaging healthy tissue to preserve the important body and organ functions. The ability to view multiple image sources at once, and therefore view radiology images (as a sub picture) within the Head Mount Monitor without being distracted from the operation is a further advantage of this technology,” explained Dr Giovanni Palleschi.

Why Sony was selected:

Thanks to the increased development of cutting edge imaging technologies, Sony offers a wide range of market leading products in Surgical, Radiology and Ultrasound fields. In the surgical field, the aim of Sony Medical is to provide endoscopic surgeons a better view inside the human body, while innovations such as OLED, as well as the complete 3D medical workflow, offer considerable advantages and new techniques for improved treatment and patient care.

3D viewing is one of the advantages of robot-assisted laparoscopic surgery that has enabled surgical techniques to evolve. However, the financial commitment involved in purchasing and maintaining a robotic system can be difficult to justify for many hospitals. The availability of 3D viewing systems such as Sony's HMS-3000MT can be used in many types of laparoscopic surgery and represents a cost-effective and innovative solution.
