  • Patent number: 11026685
    Abstract: An adapter assembly includes an elongated body, a switch, a sensor link, and an annular member. The elongated body includes a proximal portion configured to couple to a handle assembly and a distal portion configured to couple to a surgical loading unit. The switch is configured to be toggled in response to the surgical loading unit being coupled to the distal portion of the adapter assembly. The sensor link is disposed within the distal portion of the adapter assembly and biased toward a distal position. The sensor link is longitudinally movable between a proximal position and the distal position. The annular member is disposed within the distal portion and is rotatable between a first orientation, in which the annular member prevents distal movement of the sensor link, and a second orientation, in which the sensor link moves distally to toggle the switch.

  • Patent number: 11026710
    Abstract: A surgical instrument includes a housing having a movable handle operably coupled to the housing and movable relative thereto between an initial position and a compressed position. A trigger is operably coupled to the housing within a slot defined therein and movable relative to the housing and the movable handle between an un-actuated position and an actuated position. A flange is disposed on the trigger and configured to extend distally therefrom. The flange is dimensioned to cover the slot when the trigger is moved between the un-actuated and actuated positions to avoid creating a potential pinch point between the trigger and the slot.

    Abstract: A cutting assembly for a surgical instrument. A tube assembly includes an outer tube having an outer cutting window, and an inner tube coaxially disposed within and rotatable relative to the outer tube. The inner tube includes an inner cutting window such that the inner and outer cutting windows define a cutting window of the tube assembly. A portion of the inner tube distal a proximal boundary of the cutting window may define a distal region of the inner tube. A projection is within a lumen of the inner tube with at least a portion of the projection disposed within the distal region. The projection may be an insert. The projection occupies a volume of the distal region and/or reduces a cross-sectional area of the lumen distal to the proximal boundary. The projection reduces the size of material removed through the cutting window to reduce clogging of the tube assembly.

  • Patent number: 10987211
    Abstract: Devices, systems, and methods of the present disclosure are directed to efficient and accurate removal of tissue from a three-dimensional anatomic structure, such as a breast, of a patient. For example, a cup can be positioned on the patient's breast to conform the breast (e.g. via suction) to a known three-dimensional contour, and a cutting tip can be moved along the three-dimensional contour at one or more predetermined distances from at least one surface of the cup. The cutting tip can remove tissue along the three-dimensional contour to form a skin envelope. As compared to a manual process performed by a surgeon, formation of the envelope through controlled movement of the cutting tip along the three-dimensional contour can improve control over dimensions of the envelope, thus, facilitating achievement of consistent outcomes by reducing the likelihood of complications associated with an envelope that is too thick, too thin, or uneven.

  • Patent number: 10987191
    Abstract: A triple flap nipple reconstruction is shown with preoperative incision markup lines guided by a template. The incision lines made on a patient's skin rims of flaps that are to form a reconstructed nipple. The marked-up lines define three flaps where each flap has one side in common with each of the other two flaps and also has one side in common with a part of the skin which is to be removed or de-epithelized. Also, the marked-up lines define parts of the patient's skin to be removed or de-epithelized. The surgical method thus consists of making the markup with the template with three single pedicled local dermal-fat flaps from the patient's skin and then de-epithelizing designated areas of the patient's skin, making incisions and forming, i.e., raising three flaps, forming base and elevating nipple by joining sides of de-epithelized areas, and jointing the three flaps.

  • 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: 10639063
    Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.

  • Patent number: 10610151
    Abstract: Disclosed are a method for measuring the level of muscle relaxation, a device thereof and an apparatus for measuring muscle relaxation, and the method respectively obtains the sampled values of the acceleration and angular velocity of the measurement site via an acceleration sensor and an angular velocity sensor or a speed sensor and an angular velocity sensor, in order to calculate the degree of muscle relaxation according to the sampled values of the acceleration and angular velocity. As the calculated results combine the sampled values of the acceleration and angular velocity of the measurement site, the accuracy of the calculated results is higher. Moreover, the measurement combines an acceleration sensor and an angular velocity sensor or a speed sensor and an angular velocity sensor, so that the apparatus for measuring muscle relaxation can be placed in any position of the measurement site without influencing the accuracy of the measured results.
