Publication number: 20230381547Abstract: A surgical instrument includes an end effector and a handle assembly. The end effector is configured to operate at a first energy level and at a second energy level. The end effector is further configured to transition between an open position and a closed position. The end effector is configured to grasp tissue in the closed position. The handle assembly includes a body, a trigger, and an activation element. The trigger is configured to pivot in a first direction relative to the body to actuate the end effector from the open position to the closed position. The activation element is configured to activate the end effector at either the first energy level or the second energy level. The trigger is configured to either activate the activation element or determine whether the end effector operates at the first energy level or the second energy level.Type: ApplicationFiled: July 11, 2023Publication date: November 30, 2023Inventors: Charles J.

Patent number: 10226246Abstract: A surgical instrument includes a handle assembly having a trigger operable to fire a staple driver to staple tissue. The instrument includes a pointed rod to which an anvil may be coupled. An anvil detection feature is included to determine when the anvil is coupled to the rod. In some versions, the anvil detection feature comprises a translatable rod that inhibits a lockout feature from disengaging. In other versions, an anvil sensing tube is disposed about the pointed rod and interferes with actuation of the trigger in a first position. A recess in the tube permits trigger to actuate when the anvil sensing tube is in the second position. Alternatively, a resilient tab is coupled to the pointed rod and resists actuation of the staple driver. A trigger lockout assembly may include a spring-loaded button that “pops” out when a push rod is actuated, thereby freeing a pivotable lockout feature.Type: GrantFiled: October 13, 2015Date of Patent: March 12, 2019Assignee: Ethicon LLCInventors: Kevin D.

Patent number: 9750629Abstract: An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. A tension release mechanism is associated with the tension element.Type: GrantFiled: September 18, 2009Date of Patent: September 5, 2017Assignee: ETHICON ENDO-SURGERY, INC.Inventors: Daniel F.

Patent number: 9549738Abstract: A surgical instrument includes a body, a pivotable trigger, and a ratcheting assembly. The ratcheting assembly may include a rotary ratchet coupled to the trigger and a pawl coupled to the body. The rotary ratchet may further include a ramp that disengages the ratchet from the pawl. A release feature may be included to selectively disengage a second member of the ratcheting assembly from a first member. In some versions, the release feature may include a rotation knob or a slidable handle. In another configuration, the ratcheting assembly may have a first member coupled to an actuator and a second member coupled to the body. The assembly may include a lock member coupled to the body that selectively engages a plurality of teeth disposed on the actuator. Alternatively, the assembly may include a pivotable pawl coupled to the actuator that engages one or more notches formed in the body.Type: GrantFiled: January 5, 2012Date of Patent: January 24, 2017Assignee: Ethicon Endo-Surgery, LLCInventors: Venkataramanan Mandakolathur Vasudevan, Adam R.

Patent number: 9095340Abstract: A surgical stapler comprises an anvil assembly, an anvil shaft, a driver, an actuating arm, a safety switch, and a safety feature. The anvil assembly couples with the anvil shaft. The driver drives a plurality of staples into tissue. The actuating arm is in communication with the surgical stapler and is configured to actuate the driver to drive the plurality of staples into tissue. The safety switch is moveable between a locked and an unlocked position. The safety switch prevents operation of the actuating arm when the safety switch is in the locked position. The safety switch enables operation of the actuating arm when the safety switch is in the unlocked position. The safety feature may prevent operation of the driver even when the safety switch is in the unlocked position or prevent operation of the safety switch.Type: GrantFiled: January 5, 2012Date of Patent: August 4, 2015Assignee: Ethicon Endo-Surgery, Inc.Inventors: Kevin D.
