Modern Creative Technologies and Their Applications in VR Based Laparoscopic Surgery Simulation

Tue 25th Jul, 6:30 for 7:00pm

Bournemouth University, Talbot Campus (Poole), Kimmeridge House, Room K103 (Map)

Organised by the BCS Animation and Games Development SG, and Bournemouth University


With the development of computer graphic and haptic devices, training surgeons with virtual reality technology has proven to be very effective in surgery simulation. Due to the various unsolved technical issues, the laparoscopic surgery simulation has not been widely used. Such issues include modelling of complex anatomy structure, large soft tissue deformation, frequent surgical tools interactions, and the rendering of complex material under the illumination. A successful laparoscopic surgery simulator should integrate all these required components in a balanced and efficient manner to achieve both visual/haptic quality and a satisfactory refreshing rate. In this talk, we propose an efficient framework integrating a set of specially tailored and designed techniques, ranging from deformation simulation, collision detection, soft tissue dissection and rendering. This framework can be used as a low level engine for surgery simulation by integrating and optimizing modern creative technologies.


Bowel cancer is the fourth most common cancer in the UK. Around 41,000 people were diagnosed with bowel cancer annually in the UK, that's more than 110 people a day. Although it is estimated that 90% of the cases are suitable for a laparoscopic approach, there has been lack of surgeons trained to perform such demanding operations. This is particularly true for rectal cancer surgery which is the most complex and technically challenging for the laparoscopic colorectal surgeons. Because of the ethical and cost reasons, training capable surgeons for such complex operations has proven extremely difficult both in this country and around the world. Medical simulation is seen to be a viable training alternative and has proven beneficial in significantly reducing clinical errors, improving survival and relapse rates.
