Summary
Larger diameter blades (≥20 mm) and oscillating cutting modes on power morcellators significantly reduce tissue spill during surgical procedures. These features, combined with contained morcellation, enhance surgical safety by minimizing particle dissemination.
Area of Science:
- Surgical Technology
- Minimally Invasive Surgery
- Gynecologic Oncology
Background:
- Power morcellators are used in minimally invasive surgery to remove large tissue specimens.
- Tissue spill during power morcellation is a concern due to potential for spreading cancerous cells.
- Optimizing power morcellator features can improve surgical safety and patient outcomes.
Purpose of the Study:
- To evaluate the impact of power morcellator features on the amount of tissue spill.
- To assess how blade diameter, cutting mode, and rotation speed affect tissue containment.
- To analyze tissue spill during different phases of the morcellation process.
Main Methods:
- An in vitro study was conducted in a laparoscopic skills lab.
- Beef tongue specimens were used for power morcellation trials.
- Features evaluated included blade diameter (12.5 mm, 15 mm, 20 mm) and cutting mode (circular vs. oscillating).
Main Results:
- Larger blade diameters (≥20 mm) significantly reduced the weight and number of spilled particles.
- Oscillating cutting mode resulted in less total tissue spill compared to circular cutting (6.8 g/100 g vs. 21.3 g/100 g, p = .01).
- Increased blade diameter led to larger spilled particle sizes and delayed tissue spinning due to torque.
Conclusions:
- Power morcellators with oscillating blades and large diameters (≥20 mm) minimize tissue spill.
- Using larger diameter blades results in larger spilled particles and fewer morcellation repetitions.
- Combining these features with contained morcellation techniques further enhances safety by reducing tissue dissemination.
