  • Patent number: 9901670
    Abstract: A device for irrigation and/or insufflation during endoscopic surgery/procedures in a body cavity, comprising a first fluid pump device to deliver fluid to the body cavity, a second fluid pump device to move fluid from the body cavity, a control unit connected to the first and/or second fluid pump device, a blood pressure measuring device, wherein the control unit derives a control signal based on a signal from the blood pressure measuring device, and sends the control signal to the first fluid and/or second fluid pump device, wherein the control signal is derived by processing the signal from the blood pressure measuring device using a correlation factor in the device, dependent on the relationship between a blood pressure measurement signal, and a perfusion pressure of the body cavity, wherein the first and/or second fluid pump device controls the pressure in the body cavity based on the control unit's control signal.

  • Patent number: 8801654
    Abstract: A pressure and a vision regulation method and device for irrigation of a body cavity (1), in which an inflow liquid pump (2) pressurizes the irrigation liquid in a feed line (13) and an outflow device (3) or an external suction source (20) drains the irrigation liquid from the body cavity (1) through a tubing (16) into a waste container (17). A control unit (4) controls either the inflow liquid pump (2) only or both the inflow liquid pump (2) and the outflow device (3) depending on an inflow irrigation liquid pressure from a pressure sensor (5). The method and the device are combined with a method for detecting blood cells, red blood cells, haemoglobin and/or debris in liquid coming from a surgical site to provide an automatic control and rinsing system with clear vision in the viewing area of the operational site.

  • Publication number: 20130018400
    Abstract: The present invention relates to a method for determining a utilization level (UL; ULtot) indicating a degree of utilization of a re-usable cutting accessory (4) for endoscopic surgery, such as an arthroscopic shaver blade, removably connectable to a handpiece (2) comprising a motor (21) driving the cutting accessory (4) during surgical procedures. The method provides a reliable measure of the utilization level of the cutting accessory (4) by determining the utilization level (UL) of the cutting accessory (4) through calculation of at least one utilization factor (UF1, UF2) that is calculated based on a torque (40) measured when said cutting accessory (4) is driven by said motor (21).

  • Publication number: 20120116168
    Abstract: A device and method are provided for flushing during endoscopic surgery to solve the problem of debris in the operating cavity. Included is the ability of reversing the inflow and outflow channels of the endoscope to make possible the beneficial cleaning of the ports of the endoscope from debris and e.g. bone particles without a need for removal of the optical instrument during such flushing procedure and consequently avoiding loss of pressure in the body cavity and spillage. Increased flushing occurs by providing a pressure-holding valve in the proximal opening of the double-channel endoscope, where the optical instrument is inserted, making it possible to remove the optical instrument and then enable the full channel of the endoscope sheath to be used for efficient evacuation of debris without loss of pressure in the operating cavity or spillage on the floor.
