    Abstract: A dual function arthroscopic blade provides multiple cutting surfaces of differing cut aggressiveness for selective engagement of the desired cutting blade without retracting the instrument for changing cutting members to apply a different set of cutting edges, or blade. An inner rotating member within a stationary outer cutting member provide cutting edges defined by cutting windows on the inner and outer cutting members, and a rotational drive applies an oscillating rotation such that one of the cutting windows, corresponding to one of the sets of cutting edges, engages an extraction region such as tissue or bone. The use of different sized cutting windows allows variance in the aggressiveness of the cut, and allows selection of another cutting window by rotating the cutting member to align the selected cutting edges without requiring extraction and reinsertion in order to attach a different blade with a different cut aggressiveness.

  • Patent number: 9498279
    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.

    Abstract: A cutting apparatus has a handle and a hollow needle having a first end connected to the handle and a second end. The needle outer diameter is about 0.04 inch or less. An end cap is formed from a blank material. Preferably, at least one bridge is formed between the end cap and the blank material. The end cap is welded to the second end to enclose the needle and then the bridge is cut. The end cap has substantially flat inner and outer surfaces. The needle has a port and a hollow cutter that slides within the needle. The cutter has a first end connected to a drive, and a second end having a cutting edge. An outer cutter diameter is less than the needle inner diameter. The drive reciprocates the cutter within the needle to perform a cut.

  • Patent number: 9119661
    Abstract: An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel.
