Patent number: 11497497Abstract: The present disclosure relates to a surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes a cartridge receiving half-section defining an elongated channel member configured to releasably receive a firing assembly and a single use loading unit. A lockout structure prevents insertion of the single use loading unit into the channel member after the firing assembly is mounted to the cartridge receiving half-section. Alternatively, the lockout structure prevents full insertion of the firing assembly into the cartridge receiving half-section, if the single use loading unit is not engaged with the firing assembly.Type: GrantFiled: December 12, 2019Date of Patent: November 15, 2022Assignee: Covidien LPInventors: Arvind Kumar Gupta, Harshottam Singh Dhakad, Kiran Garikipati, Nikhil R. Katre, Vinayan Vivekanandan, Salman Kapadia

Patent number: 11033264Abstract: A fastener applying apparatus (20) includes an anvil half-section (100) and a cartridge receiving half-section (200) having a distal portion dimensioned to releasably receive a single use loading unit (“SULU”) (400) and a proximal portion configured to support a firing assembly (500). The firing assembly includes a stationary housing (502) and a firing lever (516) having one or more lever guide projections (522). The firing lever is slidable from a proximal end of the stationary housing to a distal end of the stationary housing to define a firing stroke. A clamping lever (300) is movable from an undamped position to a clamped position to releasably secure the distal anvil portion in close approximation with the SULU. The clamping lever defines one or more lever guide slots (316). The lever guide projection(s) is positioned to enter the lever guide slot(s) upon initiation of the firing stroke to inhibit movement of the clamping lever to the undamped position during the firing stroke.Type: GrantFiled: November 4, 2013Date of Patent: June 15, 2021Assignee: Covidien LPInventors: Arvind Kumar Gupta, Harshottam Singh Dhakad, Kiran Garikipati, Nikhil R.
