The purpose of P.O.P. Pulsating organ perfusion was developed for simulation of operations in minimally invasive surgical techniques and opens up new perspectives in laprascopy/thoracoscopy training.
 
Functional Principle  The central artery of animal organs or organ complexes is catheterized and connected to the pump of the P.O.P. simulation trainer. The perfusion medium (coloured tap water) in the pelvitrainer is conveyed into the organ by the pump. The pump works with an electronically controlled frequency of approximately 65 / min and is pressure-controlled (maximum pressure approximately 140 mmHg). The organs are supported on a perforated metal grid. The perfusion fluid passes back into the simulation trainer via side branches of the ateries, veins and parenchymal lesions.
 
P.O.P. ensures progress Operations can be carried out under most realistic conditions on animal organs or organ complexes with the P.O.P. simulation trainer: 
- abdominal surgery (liver, gallbladder, small intestine, colon, spleen etc.) 
- thoracic surgery (heart, lungs, aorta) 
- urological surgery (kidney, ureter, adrenal) 
- vascular surgery (aorta, arteries, veins) and 
- gynecological surgery (adnexae, cysts etc.)
 
Perfect surgery as a result of optimal training
 
Learning of standard operations P.O.P. simulates all types of hemorrhages (parenchymatous, capillary, arterial, venous). It is thereby not only possible to learn standard operations, but also to master hemorrhagic complications.
Control of complications In contrast to animal experiments, the exercises can be repeated as often as desired and almost without any time limitations.
 
Learning of new techniques Further more, P.O.P. is also very suitable for experimenting with new techniques and enables the results to be checked immediately.
Unlimited in time and repeatable All technologies familiar from clinical work such as high frequency (unipolar, bipolar), lasers, ultrasound dissector, aquadissector etc. can be used in the P.O.P. simulation trainer.
 
P.O.P. replaces animal experiments
 
P.O.P. replaces animal experiments Up to now, animal experiments where the only adequate means of practicing clinical operations. Operations on anesthetized animals are expensive, require a demanding organization. In industrial countries, they also need official authorization.
