Ope­ra­ting in vir­tu­al space

Vir­tu­al rea­li­ty is used to train sur­ge­ons in a play­ful way in working with sur­gi­cal robots.

Pre­cise cuts, small wounds: when sur­ge­ons use the exten­ded arms of sur­gi­cal robots to per­form mini­mal­ly inva­si­ve sur­ge­ry, i.e. the smal­lest incisi­ons in tis­sue, they have pos­si­b­ly prac­ti­sed this befo­re­hand by using the vir­tu­al rea­li­ty trai­ning pro­gram­me from the Pots­dam-based ani­ma­ti­on stu­dio Baby Giant Hol­ly­berg.

The VR experts were com­mis­sio­ned by Ava­te­ra, a manu­fac­tu­rer of medi­cal robots based in Jena, to crea­te a digi­tal envi­ron­ment with several levels to train sur­ge­ons on ope­ra­ting the robot. A trai­ning pro­gram­me which is necessa­ry befo­re one can actual­ly obtain a sur­gi­cal license.

Medi­cal robots are now in gre­at demand, espe­cial­ly in sur­ge­ry, whe­re they are used for key ope­ra­ti­ons in gynae­co­lo­gy and uro­lo­gy. Pre­cise and care­ful work is an important gua­ran­tee for a suc­cess­ful ope­ra­ti­on. The exten­ded arm in the form of the tech­ni­cal assi­stant takes over from the doctor’s famous “steady hand” . 

Avatera’s model could have also ori­gi­na­ted from the set of a sci­ence fic­tion film. It is ent­hro­ned in the ope­ra­ting theat­re with four lar­ge arms and is con­trol­led by a com­pu­ter. During the trai­ning pro­gram­me, you sit at the con­trol­ler and simul­ta­ne­ous­ly lean with your body into the VR glas­ses. Baby Giant Hol­ly­berg col­la­bo­ra­ted with ano­t­her two other part­ner com­pa­nies, who were respon­si­ble for the pro­gramming (ITK Engi­nee­ring, Ber­lin) and the user inter­face (Design­Lab, Wei­mar), on the digi­tal simu­la­ti­on and deve­lo­ping the con­cept and visualisation. 

A cer­tain approach was important at the out­set. The VR trai­ning pro­gram­me had to intro­du­ce the users to basic func­tio­n­a­li­ties and then work out the nuan­ces that would later be so essen­ti­al in the ope­ra­ting theatre.

“How can we suc­ceed in designing a trai­ning cour­se in such a way that it will be moti­vat­ing?” was ano­t­her important con­si­de­ra­ti­on. To this end, Baby Giant Hollyberg’s team instal­led high score lists, hurd­les for the next level and remin­der e-mails. The gami­fi­ca­ti­on ele­ments keep the users inte­res­ted and pro­vi­de moments of suc­cess. A who­le obsta­cle cour­se of tasks has to be mas­te­red wit­hin the twel­ve levels. Ins­tead of hand­ling blood ves­sels and ner­ve cords, the sur­ge­ons are now working in the digi­tal simu­la­ti­on with Lego bricks being sor­ted into boxes, glass balls lifted out of bowls without being bro­ken, or need­les with thread that has to be fed around dif­fe­rent sur­faces. Litt­le by litt­le, they advan­ce in a play­ful way toward tho­se skills that are then used in the real ope­ra­ti­on. The sur­ge­ons get a feel for the right atmo­s­phe­re becau­se they can see a blur­red image of the ope­ra­ting theat­re in the back­ground through the VR glasses. 

Howe­ver, the tar­get group - and par­ti­cu­lar­ly the expe­ri­en­ced, older sur­ge­ons - is not known for being typi­cal gamer and game con­so­le fans. It was important to devi­se a pro­gram­me for them that did­n’t seem too pom­pous or dis­tract from the essen­ti­al, yet was simul­ta­ne­ous­ly suf­fi­ci­ent­ly chal­len­ging. The VR spe­cia­lists from Babels­berg could draw on their many years of working in the world of enter­tain­ment to achie­ve this balan­ce bet­ween enter­tain­ment, qua­li­ty and visual­ly appe­aling design. As an ani­ma­ti­on and vir­tu­al rea­li­ty stu­dio ope­ra­ting out of Pots­dam-Babels­berg and Los Ange­les, they actual­ly come from the film indus­try. In the mean­ti­me, though, most of their work is being done for indus­tri­al cli­ents who are sup­por­ted with vir­tu­al rea­li­ty, exten­ded rea­li­ty, aug­men­ted rea­li­ty and mixed rea­li­ty applications. 

“Sto­ry­tel­ling in the indus­tri­al sec­tor is not about clas­sic sto­ry­tel­ling. It’s more about the mes­sa­ge. What kind of mes­sa­ge do we want to com­mu­ni­ca­te, how do we talk intern­al­ly with the employees, what do we want to com­mu­ni­ca­te with the digi­tal app­li­ca­ti­on? Much of it revol­ves around inter­nal com­mu­ni­ca­ti­on,” says Hei­ko Nem­mert, CEO / Mana­ging Part­ner and Pro­ject Manager. 

In the case of the Ava­te­ra pro­ject, vir­tu­al rea­li­ty is the chan­ce here to help shape future­me­di­cal tech­no­lo­gy. Once the robot is in use, it would theo­re­ti­cal­ly even be pos­si­ble for several peop­le to join via the Inter­net and take a digi­tal look into the insi­de of a human through their glas­ses. For examp­le, a spe­cia­list from New York could be direct­ly con­sul­ted to advi­se on tre­at­ment in a Munich ope­ra­ting theat­re. This is whe­re medi­ci­ne and media tech­no­lo­gy open up more than just the third dimension.
