  • Patent number: 10660663
    Abstract: A bone cutting surgical instrument includes features to mitigate heat generation during use. Excessive heat can be detrimental to bone health as well as to the instrument itself. In one example a liquid dispensing feature provides a flow of cooling liquid to an ultrasonic blade via a lumen in a waveguide of the instrument. In another example, the blade has a serrated edge with a plurality of teeth arranged in a pattern to provide dimension and space during cutting actions. In another example, the blade has an oversize distal portion that creates an oversize slot when cutting to avoid excessive contact between the cut bone and proximal portions of the blade. In another example the blade includes an irrigation slot and also a micro slot in a distal end of the blade that connects with the irrigation slot.

  • Patent number: 10646300
    Abstract: A surgical instrument includes a body, an ultrasonic transducer assembly, and a transducer lock having a lock member configured to move between unlocked and locked positions. The transducer assembly is rotatably mounted along a longitudinal axis within the body such that the transducer assembly is configured to selectively rotate about the longitudinal axis. With the lock member in the unlocked position, the transducer assembly is configured to be selectively rotated about the longitudinal axis relative to the body. With the lock member in the locked position, the transducer lock is configured to seize the transducer assembly and inhibit rotation relative to the housing for coupling with an acoustic waveguide. The surgical instrument may also include an integral torque wrench for coupling the acoustic waveguide with a predetermined torque and an integral torque indictor for signaling to a user that the acoustic waveguide is coupled with the predetermined torque.

  • Patent number: 10603129
    Abstract: A surgical instrument includes an instrument body, an ultrasonic transducer assembly, and a slip lock having an arrester. The transducer assembly is rotatably mounted along a longitudinal axis within the body such that the transducer assembly is configured to selectively rotate. The arrester is configured to move relative to the ultrasonic transducer assembly between an engaged position and a disengaged position and has a catch portion and a deflectable portion. The catch portion is configured to seize the transducer assembly and selectively inhibit rotation for rotatably coupling with the acoustic waveguide up to a predetermined torque. The deflectable portion is configured to deflect relative to the transducer assembly upon receiving a torque greater than the predetermined torque. Accordingly, the catch portion releases the transducer assembly to slip relative to the catch portion for limiting coupling of the transducer assembly with the acoustic waveguide to the predetermined torque.

  • Publication number: 20190239918
    Abstract: A surgical instrument comprises a body assembly and an end effector. The body assembly includes a control module, an orientation sensor communicatively coupled to the control module, and an energy component. The energy component is operable to activate the end effector at a plurality of energy settings. A storage device is communicatively coupled to the control module and includes a plurality of gesture profiles and corresponding energy settings. The control module is configured to set the energy setting of the energy component to a corresponding energy setting in response to a correlation between the output of the orientation sensor and a gesture profile. In some versions, the control module modifies the energy setting based upon output from a force sensor that measures the force on the end effector. The control module may also decrease the energy setting in response to an anomalous acceleration or deceleration detected by an accelerometer.

  • Patent number: 10322028
    Abstract: An apparatus for delivering therapeutic agent to an eye comprises a body, a cannula, a hollow needle, an actuation assembly, and a detection/visualization system. The cannula extends distally from the body and is sized and configured to be insertable between a choroid and a sclera of a patient's eye. The actuation assembly is operable to actuate the needle relative to the cannula to thereby drive a distal portion of the needle along an exit axis. The cannula may be inserted through a sclerotomy incision and advanced through the choroid to deliver the therapeutic agent adjacent to the potential space between the neurosensory retina and the retinal pigment epithelium layer. The detection/visualization system is operable to detect or visualize penetration of the choroid of a patient's eye and provide feedback to the operator and/or automatic control of the apparatus based on penetration of the choroid.

    Abstract: A variety of methods for managing a re-usable ultrasonic medical device may include a medical device control module capable of receiving functional data from a user assembled or reassembled ultrasonic medical device, and notifying the user if a value of the functional data lies within an acceptance range. If the value of the functional data does not lie within the acceptance range, the control module may prompt a user to reassemble the device or to clean or replace one or more components thereof. The functional data may relate to a clamp force of a jaw assembly, an impedance or resonant frequency value of an ultrasonic blade, or a mechanical displacement value of one or more moving components of the device.
