Patent number: 11666327Abstract: A method and device for controlling the compression of tissue include clamping tissue between a first clamping member and a second clamping member by driving at least one of the clamping members with an electric motor toward a predetermined tissue gap between the clamping members and, during the clamping, monitoring a parameter of the electric motor indicative of a clamping force exerted to the tissue by the clamping members. The method and device include, during the clamping, controlling the electric motor, based on the monitored parameter, to limit the clamping force to a predetermined maximum limit.Type: GrantFiled: December 23, 2020Date of Patent: June 6, 2023Assignee: Covidien LPInventors: Michael P.

Patent number: 11317909Abstract: A surgical device is provided, the surgical device including a first driver for performing a first movement function; a second driver for performing a second movement function; a first rotatable drive shaft configured, upon actuation, to cause selective engagement of one of the first and second drivers with a second rotatable drive shaft, wherein the second rotatable drive shaft is configured to drive the selectively engaged one of the first and second drivers. Third and fourth drivers may also be included. The drivers may function to rotate a shaft portion of the surgical device relative to, and about the longitudinal axis of, a handle; move a jaw portion relative to the shaft portion; move a first jaw relative to a second jaw; and/or move a surgical member within the second jaw.Type: GrantFiled: September 13, 2019Date of Patent: May 3, 2022Assignee: Covidien LPInventors: Michael P.

Patent number: 10660626Abstract: A surgical system includes an intelligent surgical device having a drive motor supported in the housing and being in electrical communication with the power source; and control circuitry. The control circuitry includes a feedback system for monitoring a condition of the surgical device during a use thereof and for changing an operative parameter of the surgical device when a change in the monitored condition occurs. The surgical system includes a non-intelligent loading unit for selective connection to the housing of the surgical device and which is actuatable by the drive motor. During operation, the drive motor actuates the loading unit from a first condition to a second condition; and when the loading unit achieves the second condition, a change in the at least one monitored condition occurs and an operative parameter of the surgical device is changed.Type: GrantFiled: July 18, 2017Date of Patent: May 26, 2020Assignee: COVIDIEN LPInventors: David Nicholas, Donald Malinouskas, David Zeichner
