US Patent 11938292 Laparoscopic flexible suction device and associated methodology

A laparoscopic suction/irrigation device of the disclosed invention encases a rigid inner cannula with a flexible outer cannula, the outer cannula functioning to insulate the inner cannula from unwanted electrical discharges. Upon translating the distal end of the outer cannula beyond the distal end of the inner cannula, the outer cannula returns to a preexisting curvilinear shape. This curved extension can thereafter be positioned via a proximal handle to concavities within the surgical site for precise and effective fluid retraction.
