Objective
Traditional surgical training procedures include the use of live animals (which have limited relevance), human cadavers (which are limited in supply), live human patients (requiring experienced supervision, which is also limited in supply) and artificial organs (which have limited realism). Hence the speed and cost at which new surgeons can receive training form limiting factors to the supply of experienced practitioners. Surgical simulation techniques, and particularly the application of virtual reality (VR), are one potential solution to this problem. Indeed, such systems already exist, imported into the European market from the US and Pacific Rim Countries. Economic and social pressures on the market for the provision of health care are driving the continued use and further development of new Minimally Invasive Surgical (MIS) Procedures. The use of MIS has grown significantly in acceptance and has seen extension of its use to a large number of surgical and investigative procedures with some 300,000 carried out in 1996 (3). The proposed RTD is in response to the urgent industrial need, amongst the SME system and sub system manufacturers, represented by the Core Group of Proposers, to take advantage of recent developments in medical visualisation and precision actuator systems and provide a technological solution to the two main product limitations, retarding market take up.
Specifically, the provision of: - Increased functionality within next generation hardware systems that provide, simulated tactile feedback of tissue deformation and the forces and torques generated at the end of the instrument' resulting from the simulated action, increasing the realism of the system. - More efficient software systems able to run on low cost computing platforms, reducing total system cost and broadening the range of applications. This will enable the domestic supply base to improve competitiveness, reducing the estimated 6.6 MECU/pa of imports for surgical training systems into the EU and potentially providing differentiated products with which to gain access to the US and Pacific Rim markets. It could also help to improve the performance of healthcare training budgets and provide surgeons with experience of novel procedures, not commonly undertaken or accessed for training purposes.
The industrial objective of the proposed RTD is to provide the European healthcare sector with advanced surgical simulation technology that facilitates improved training and visualisation of a wide range of procedures, possessing the following attributes: - Increased functionality within hardware systems that provide, six axis simulation of the tactile feedback of tissue deformation effect at the interface between the instrument and patient, increasing the realism of the - More efficient software systems able to run on low cost (<10 KECU) computing platforms, reducing total system cost and broadening the range of applications. To achieve this a number of technical objectives must be met in the development of the simulation system's component elements and sub systems.
These include the development of an integrated system able to: - Input patient specific medical data, produced from MRI, CT, PET and ultrasound data sources - Manage data to minimise geometry throughput (triangles per see) and fill rate (pixel per see) computational operations - Construct a 3D representation of that 'managed' date - Read input from hardware peripherals - Calculate real time deformation of tissue and organs as a result of the action of the surgical tools Introduce system constraints that mimic actual procedures - Calculate displacement forces - Feedback those forces to the users grip, in 6 axes After completion of the proposed RTD, the results will be integrated into a demonstration system to promote the benefits and range of applications of the generic technology to SME medical equipment suppliers and their customer base. The partners will work together, within a two-year period after the end of the project, to develop marketable versions of the generic technology. The Core Group of Proposers, together with their existing customer base, provide a rapid and robust route to market for such a system.
