Sony HMS-300MT: 3D head-mounted viewer to improve the work of surgeons in their interventions

In line with its strategy of being a benchmark in medical technologies in Spain, the Severo Ochoa University Hospital has carried out a course, as part of the master's degree in endoscopic ear surgery, using Sony's HMS-3000MT head-mounted viewer to analyze the first live surgeries of its kind in Spain and share best practices and innovations.

In this sense, This is one of the first endoscopic ear surgeries performed with the HMS-3000MT system. Sony in Spain, whose result offers several advantages over traditional microsurgery, requiring external incisions, a longer recovery period and less technical skill.

As part of your training and professional development, among the participants of the course organized by the Severo Ochoa University Hospital from Madrid, at the end of last January, there were attending doctors, residents and department heads, with more than professionals from all over Spain who attended this surgery broadcast live from the amphitheater of this center.

Innovation in surgery

Endoscopic ear surgery is widely used in the treatment of chronic ear infections., cholesteatomas and other conditions. The margin of error is very low, although any failure can leave the patient deaf. The availability of advanced vision imaging systems plays a fundamental role in surgery to ensure both the safety and success of interventions, in addition to improving the comfort of the surgeons themselves.

In this last aspect, It should be noted that traditional video screens can cause stress and premature fatigue for surgeons during multi-hour interventions., since the technology requires them to alternate their view between the instruments and an independent monitor.

As Dr. José Carlos Casqueiro assures, who has performed two operations during the course of the master's degree and who is also a member of the International Working Group of Endoscopy Ear Surgery (the international endoscopic ear surgery working group), “during operations I like to see what I am doing with a clear and sharp image”.

Eliminating the need to switch between patient and screen can have a very positive effect on a surgeon's resilience, in addition to providing a wider field of vision that allows anatomy to be recognized more easily, and with this objective, those responsible for the Severo Ochoa Hospital showed this innovative solution to the course participants..

Stereoscopic viewing

The center has trusted Sony to carry out the first two live operations in Spain using the 3D head-mounted viewer HMS-3000MT, that allows endoscopic and laparoscopic surgery to be addressed, responding to the needs demanded by professionals, as well as contribute to identifying dissection planes and anatomical structures thanks to 3D HD visualization.

Sony HMS-3000MT is a personal visualization system that allows surgeons to view images from 3D and 2D color surgical cameras. This device consists of the HMI-3000MT image processing unit, responsible for receiving video images from the surgical camera and sending them to the HMM-3000MT head-mounted viewer, providing stereoscopic viewing.

The screen is adjustable for greater comfort during long periods of operation and also allows a 'down' view of the operated area. Unlike passive 3D systems, Dual screen design uses two independent OLED panels to display images for the user's left and right eye, which avoids crossings or double images in favor of natural and fluid images.

The HVO-3000MT head-mounted viewer and 3D HD video recorder were used during a masterclass of the course to live stream the two operations from the operating room at the Severo Ochoa Hospital.. For this, the latest 3LCD projector with laser light source from Sony was used., specifically the VPL-FHZ700L model.

For the doctor Casqueiro, “the 3D capability of the head-mounted viewer is truly spectacular. It takes a while to get used to the realistic surgery., but once you are familiar with it, you get amazing image quality. Sony's device is very comfortable to work with and has great potential, not just for surgery, but also for the educational sector”.

Ergonomics and high image quality

The comfort of the HMS-3000MT headset has helped improve posture and reduce eye and upper body movement, which has made it easier for the surgeon to move more comfortably than on a conventional operating table. The reduction in fatigue has also contributed to improving the effectiveness of your movements.

Its ergonomic design, This system adds the reproduction of endoscopic images with surprising depth and clarity. The HMS-3000MT viewfinder's image quality at close range helped create accurate contrast and color reproduction, in addition to improving the size of the projected image.

David Franco, responsible for the Sony Europe channel account, points out that “the ergonomic design of the HMS-3000MT allows surgeons to concentrate on the surgical procedure without having to change their viewing angle.”. Besides, Advanced 2D/3D technology offers greater image clarity. This combination of quality and comfort that Sony offers has three advantages, according to surgeons' comments so far: less fatigue, better results and reduction in operations time”.

In this same line, Dr. Casqueiro emphasizes that “it is so realistic that it makes me feel very close to endoscopic ear surgery.”. It's like a microscope that allows you to see in 3D.".

The availability of 3D visualization systems such as the HMS-3000MT can be used in many types of laparoscopic surgery and represents a cost-effective and innovative solution., without the financial commitment of a robotic system.
