Publication number: 20230211069Abstract: A fluid pump system having a first fluid pump for pumping fluid from a source to a surgical site and a second fluid pump for removing fluid from the surgical site at a first predetermined rate, wherein said fluid pump system intermittently operates in conjunction with a surgical tool which, when operational, removes fluid from the surgical site at a second predetermined rate greater than said first predetermined rate, the improvement including a sensor for sensing a predetermined parameter of the surgical tool and providing an output signal indicating that the surgical tool is operating; and an actuating means responsive to said output signal to actuate said second fluid pump to remove fluid from the surgical site at second predetermined rate.Type: ApplicationFiled: March 13, 2023Publication date: July 6, 2023Applicant: Conmed CorporationInventors: Eric Stubkjaer, David D. Blight, Peter C. Miller, Karl W. Guenther

Patent number: 9308315Abstract: A dual pump irrigation/aspiration pump system that is capable of operating in a plurality of different modes suitable for a variety of different endoscopic surgical procedures. The system monitors actual or calculated intra-articular pressure and adjusts flow to maintain surgeon requested pressure at the surgical site while controlling outflow. The irrigation/aspiration pump system has an inflow pump and tubing dedicated to communicating fluid to the surgical work site and an outflow pump and tubing dedicated to removing fluid from the work site at a controlled rate. The system has the ability to alter the outflow fluid flow rate to accommodate a surgical tool to declog the surgical tool in the event of blockage.Type: GrantFiled: October 24, 2013Date of Patent: April 12, 2016Assignee: Linvatec CorporationInventors: Eric Stubkjaer, David D.

The irrigation/aspiration pump system has an inflow pump and tubing dedicated to communicating fluid to the surgical work site and an outflow pump and tubing dedicated to removing fluid from the work site at a controlled rate. The system further has different size inflow and outflow pumps and tubing cassettes, means for altering the outflow fluid flow rate to accommodate a surgical tool and a means for declogging the surgical tool in the event of blockage. In a preferred embodiment a pressure control system provides inferred pressure information representative of the pressure at the work site.Type: ApplicationFiled: October 24, 2013Publication date: February 13, 2014Applicant: Linvatec CorporationInventors: Eric STUBKJAER, David D.
