Document Type and Number:
WIPO Patent Application WO/2019/169735
Kind Code:
A1
Abstract:
Disclosed is a device for regulating a negative-pressure suction flow for minimally invasive surgery, the device comprising a suction catheter (6), a flow regulator (2) and a negative-pressure pipe (7), wherein one end of the negative-pressure pipe (7) is in communication with a negative-pressure source (1), and the other end thereof is in communication with a waste liquid bottle (3); and a suction end of the suction catheter (6) extends into a surgical site for drawing surgical waste, and the other end thereof is inserted into the waste liquid bottle to discharge the waste into the waste bottle under negative pressure, characterized in that the flow regulator (2) for regulating the suction pressure or the flow at the suction end of the suction catheter (6) is located between two ends of the negative-pressure pipe (7) instead of two ends of the suction catheter (6) so as to ensure the suction catheter (6) has a smooth suction channel. According to the present invention, the blocking of the negative-pressure suction channel is avoided, and the safety of surgery is improved.
