Patent number: 11272947Abstract: A surgical instrument includes a housing, a movable handle, a trigger, a drive assembly operably coupled between the movable handle and an end effector assembly such that movement of the movable handle from an initial position to a compressed position manipulates the end effector assembly, and a linkage operably coupled between the trigger and a knife such that movement of the trigger from an un-actuated position to an actuated position rotates the linkage to deploy the knife relative to the end effector assembly. A drive housing of the drive assembly inhibits rotation of the linkage when the movable handle is disposed in the initial position and the trigger is disposed in the un-actuated position. The drive housing cams along a surface of the linkage to urge the linkage to rotate when the movable handle is returned towards the initial position, thereby returning the trigger towards the un-actuated position.Type: GrantFiled: July 9, 2018Date of Patent: March 15, 2022Assignee: COVIDIEN LPInventors: Stephen J.

Patent number: 11272972Abstract: In some embodiments, a method includes identifying a nerve extending across a transection path; administering a cooling therapy to the identified nerve at a location proximal to the transection path so as to degenerate the identified nerve across the transection path prior to or during surgical transection along the transection path, wherein cooling the identified nerve prevents or reduces neuroma formation at a transected end of the nerve after transection of the nerve. In some embodiments, a method includes degenerating a portion of a nerve while preserving a connective tissue framework of the nerve. During or after the degeneration, the preserved connective tissue framework may be transected at a transection location distal to the treatment location. The regeneration of the nerve may be repeatedly disrupted for a period of time to reduce a regenerative rate of the nerve and delay neuroma formation.Type: GrantFiled: October 3, 2019Date of Patent: March 15, 2022Assignee: Pacira CryoTech, Inc.Inventors: John Allison, Jessica Preciado Dummett, Michael Hsu
