Patent number: 10939810Abstract: A surgical system includes a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument defines a second channel. A valve coupled to the first instrument controls fluid flow through the first channel, such that impedance of fluid flow through the first channel is substantially the same without the second instrument received in the first channel and with the first channel partially blocked by the second instrument. In another aspect, a surgical apparatus includes an outer member and an inner member received within the outer member to define a first channel therebetween. The inner member houses an optical lens and defines a second channel for receiving a surgical instrument. The first and second channels are configured such that a pump having an inflow rate of up to about 0.7 L/min connected to the second channel can maintain fluid pressure inside an organ.Type: GrantFiled: September 11, 2018Date of Patent: March 9, 2021Assignee: Covidien LPInventors: Cemal Shener-Irmakoglu, Christopher R.

Patent number: 9855383Abstract: A fluid flow device includes a housing configured to releasably mate with a surgical control unit for controlling fluid flow during a surgical procedure. First and second ports measure fluid pressure within a fluid path provided within the housing. The fluid flow device includes a restrictor for restricting fluid flow at a restriction location along the fluid path. The first port is located upstream of the restriction location and the second port is located downstream of the restriction location. A fluid pump is provided within the housing.Type: GrantFiled: March 5, 2015Date of Patent: January 2, 2018Assignee: Smith & Nephew, Inc.Inventors: Cemal Shener, Kenneth W.

Patent number: 9655640Abstract: A dual function arthroscopic blade provides multiple cutting surfaces of differing cut aggressiveness for selective engagement of the desired cutting blade without retracting the instrument for changing cutting members to apply a different set of cutting edges, or blade. An inner rotating member within a stationary outer cutting member provide cutting edges defined by cutting windows on the inner and outer cutting members, and a rotational drive applies an oscillating rotation such that one of the cutting windows, corresponding to one of the sets of cutting edges, engages an extraction region such as tissue or bone. The use of different sized cutting windows allows variance in the aggressiveness of the cut, and allows selection of another cutting window by rotating the cutting member to align the selected cutting edges without requiring extraction and reinsertion in order to attach a different blade with a different cut aggressiveness.Type: GrantFiled: November 4, 2013Date of Patent: May 23, 2017Assignee: Smith & Nephew, Inc.Inventors: Petter A.

Patent number: 8915903Abstract: A fluid conduit connector assembly includes a connector having a body with an inner surface defining a fluid channel. The connector also includes an inlet region for flow of fluid into the fluid channel, and an outlet region for flow of fluid from the fluid channel. The connector further includes an axial alignment member outward of the body, and a pair of flexible tabs arranged generally circumferentially of the alignment member and outward of the body. The connector can be configured as a day-side connector, transfer member with check valve, and/or patient-side connector. An implementation includes a day-side connector, a patient-side connector, and a transfer member, each of which has a pair of flexible tabs.
