CONTROLLED PRESSURE ENDOSCOPIC AND PERCUTANEOUS SURGERY

摘要

The present disclosure relates to systems and methods for controlling pressure during percutaneous and endoscopic surgeries, including percutaneous renal procedures, endoscopic uterine procedures, transurethral endoscopic procedures for the bladder or prostate, or any percutaneous or endoscopic procedure. The system can include a sheath and/or endoscope each having an inflow port providing access to an inflow channel extending from the inflow port to a distal portion of the sheath, and an outflow port providing access to an outflow channel extending from the outflow port to the distal portion of the sheath. The sheath can also include a pressure sensor configured to generate a pressure measurement, and an electronic processor configured to control fluid through at least one of the inflow port and the outflow port based on the pressure measurement.

主权项

1. A sheath cap assembly configured to enclosed a proximal end of a sheath, the cap comprising:
a main body portion comprising:
a wall portion shaped to surround the proximal end of the sheath;a closed proximal end portion; andan open distal end portion; an inflow port on the main body portion, the inflow port providing access from an irrigation source to a lumen of the sheath when the sheath cap is secured to the sheath; an outflow port on the main body portion, the outflow port providing an outlet for fluid flowing out of the sheath when the sheath cap is secured to the sheath; a pressure sensor connected to the sheath cap, the pressure sensor configured to generate a pressure measurement; and a processing unit configured to direct fluid through at least one of the inflow port and the outflow port based on the pressure measurement.
