Publication number: 20170229264Abstract: A switch comprising an interior cavity and a switching element movably disposed within the interior cavity to define a first position and a second position, the second position being different from the first position. A biasing element imparts a biasing force to the switching element to place the switching element in either the first or the second position until an external force imparted to the switching element exceeds the biasing force, thereby causing the switching element to move to the other one of the first or the second position. A biasing force-adjusting element is cooperatively engaged with the biasing element, wherein a magnitude of the biasing force is adjustable using the biasing force-adjusting element. An electrically-conductive contact, coupled to the switching element, defines a first switching state when the switching element is in the first position and a second switching state when the switching element is in the second position.Type: ApplicationFiled: April 25, 2017Publication date: August 10, 2017Applicant: Ethicon Endo-Surgery, Inc.Inventor: Kevin W.

Patent number: 9713473Abstract: A surgical instrument includes an end effector, an actuator coupled to the end effector and actuating it, a handle coupled to the end effector and having an electric motor disposed therein actuating the actuator when supplied with power, and a post-termination braking circuit including a power supply switch at the handle. The switch has a break-before-make configuration, a power-supplying state in which power is supplied to the motor, and a power-removed state in which power is not supplied to the motor. The braking circuit short-circuits power to the motor when the switch is in the power-removed state. A method for post-termination braking of the motor utilizes the permanent magnetic field to counteract inertia-induced over-stroke of the motor, drive train, and/or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power.Type: GrantFiled: April 16, 2013Date of Patent: July 25, 2017Assignee: Ethicon Endo-Surgery, Inc.Inventors: Kevin W.
