title: A novel haemostatic powder delivery device applicable in minimally invasive surgery.
abstract: Haemostatic powder is an effective solution commonly used in various open surgeries. However, there is no specific intra-abdominal delivery device for application of haemostatic powder at the bleeding site during minimally invasive surgery (MIS). In this study, design, construction and test of a novel powder delivery device were carried out. The device uses pressurized gas to deliver the haemostatic powder to the bleeding point. The effect of the gas pressure and the spraying distance on the geometry of the powder dispersion surface area was investigated and found to be significant. The findings indicate that the driving gas pressure range of 60-80 mmHg and the spraying distance range of 2-5 cm achieve the most concentrated powder dispersion surface area. Additionally, in vivo experiments confirmed the effectiveness of the device in live tissue.
