  • 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.

    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.

Surgeons of either dexterity are able to learn and operate using similar techniques and instruments heretofore not available to them. No longer must a left handed surgeon be forced into the right handed world to perform surgery. The device is designed to use existing styles of blades currently available without needing costly inventories of specially created blades for the multitude of other such devices on the market.

  • Patent number: 10201384
    Abstract: A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

  • Patent number: 10111699
    Abstract: A variety of surgical instruments include one or more elements that transmit RF energy to tissue. Some such instruments comprise a pair of jaws that open and close on tissue, with conductive tissue contact surfaces that are operable to weld tissue clamped between the jaws. Some surgical instruments also include a translating tissue cutting element. Some such instruments may be in the form of forceps having a scissor grip. When an electrosurgical instrument includes grasping jaws and tissue severing capabilities it may be desirable to avoid accidental cutting by the knife. Hence, the instrument may include a feature that prevents the knife from firing until the jaws are sufficiently closed upon the tissue. It may also be desirable to prevent the jaws from being opened until the knife has been retracted. One or both of these features can prevent the knife from being extended while the jaws are open.

Some such instruments comprise a pair of jaws that open and close on tissue, with conductive tissue contact surfaces that are operable to weld tissue clamped between the jaws. Some surgical instruments also include a translating tissue cutting element. Some such instruments may be in the form of forceps having a scissor grip. Forceps type instruments may in some instances provide a feature that allows the jaws of the forceps to be locked on tissue, so that the operator can remove his or her hands from the instrument. In such an instrument it may also be desirable to provide a circuit that is activated only when the forceps are closed and sufficient pressure is applied to the tissue between the jaws of the device.

  • Patent number: 10085681
    Abstract: A depth-control mechanism for selectively-adjusting a lancing stroke depth of a lancet carrier. The depth-control mechanism includes a positioning tab that is configured to be repositioned along an axis that is orthogonal to the lancing stroke axis of the lancet carrier. The depth-adjustment mechanism also includes a tether that is pivotally coupled between the positioning tab and the lancet carrier. The positioning tab is configured to manipulate a pivot axis of the tether to adjust the lancing stroke length of the lancet carrier.

  • Patent number: 10058336
    Abstract: Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.

  • Patent number: 10052125
    Abstract: Described herein are atherectomy catheters, systems and methods that include a distal tip region that may be moved laterally so that its long axis is parallel with the long axis of the main catheter body axis. Displacing the distal tip region laterally out of the main catheter body axis exposes an annular blade and opens a passageway for cut tissue to enter a storage region within the catheter. The annular blade may be internally coupled to a drive shaft that rotates the blade, and thus the exposed blade edge may have the same crossing profile (OD) as the rest of the distal end region of the catheter. Also described herein are gear-driven atherectomy devices that may use a cable drive shaft to actuate the annular blade. Both push-to-cut and pull-to-cut variations are described, as are methods for cutting tissue and systems including these atherectomy catheters.

  • Patent number: 10045809
    Abstract: A vessel dissector for harvesting a target vessel from a donor has a generally cylindrical tip body with a sloping channel formed along a longitudinal side. A channel bottom provides a channel depth that decreases from a distal channel end to a proximal channel end. The tip body has a crescent-shaped forward lip extending distally from the channel. An arcuate collar is slidably disposed in an arcuate recess within the tip body to selectably bridge the channel at the distal end of the channel to form a ring profile with the forward lip. A first ferromagnetic heating element is disposed along a radially outward surface of the forward lip. A second ferromagnetic heating element is disposed on a distal edge of the arcuate collar. The first and second ferromagnetic heating elements are adapted to be energized simultaneously to make a vasiform cut including a pedicle around the target vessel.
