A Comparitive Overview of Existing and Experimental Morcellators in Gynecology and Urology

In literature, little comparison data are available between various morcellators, which are used to remove large tissue masses minimally invasively. Since various morcellators are available on the market, and they are used fairly frequently, it is important to know whether the devices perform optimally, or if one is more functional than another. To this purpose, a literature research has been performed to find all previous, current and experimental morcellators and compare their morcellation rates (g/min), i.e., the removed mass divided by its removal time. The instruments were categorized by their respective working principles and significant trends were identified in the field of morcellation from the found and calculated data. The main findings are that the newest morcellators on the market, which rely on the principle of “motor peeling,” are indeed the fastest in terms of morcellation rate, yet it seems that improvements are still possible when it comes to speed and safety. Based on literature, these improvements include the use of an endoscopic bag with a custom created environment and the optimization of the continuity of the applied morcellation working principle.
