  • Publication number: 20190059953
    Abstract: The present disclosure includes a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.

The inner sleeve is rotationally disposed in the axial bore of the outer sleeve to allow the inner sleeve window to be rotated in and out of alignment with the outer sleeve window, and the shaft assembly forms a flow aperture in a distal portion when the inner cutting window and the outer cutting window are out of alignment. An electrode is carried on the inner sleeve, and a motor drive is coupled to rotate the inner sleeve relative to the outer sleeve.

    Abstract: An apparatus includes a body, a shaft assembly, an end effector, and an articulation section. The articulation section is longitudinally interposed between a distal end of the shaft assembly and a proximal end of the end effector. The articulation section is configured to flex to thereby provide deflection of the end effector away from the longitudinal axis of the shaft assembly. The articulation section includes a first frame member, a second frame member, and a sleeve. The proximal end of the second frame member is proximal to the proximal end of the first frame member. The sleeve is disposed about the first and second frame members.

  • Publication number: 20190059990
    Abstract: In a treatment system, an energy treatment instrument includes a pair of grasping pieces. An energy output source outputs electric energy to the energy treatment instrument, thereby applying treatment energy to a blood vessel grasped between the grasping pieces. A measurement section measures a blood pressure at a site related to the grasped blood vessel. A processor controls output of the electric energy from the energy output source based on a measurement result obtained by the measurement section, and thereby switches an actuation state of the energy treatment instrument between a first mode for coagulating the blood vessel and a second mode for coagulating the blood vessel target that is different from the first mode.

    Abstract: In one aspect, devices for light treatment of skin are described herein. A device described herein, in some embodiments, comprises an interior compartment having a proximal end and a distal end, and an optical aperture disposed at the distal end. The device also comprises a laser or BBL source that produces a laser or BBL beam. The laser or BBL beam has a first optical path within the interior compartment, between the proximal end and the distal end. Additionally, the first optical path exits the interior compartment through the optical aperture. The device further comprises an imaging system that receives a return signal from the aperture. The return signal received from the aperture has a second path within the interior compartment. Further, a selectively reflective optical element is disposed in the first and second optical paths. The selectively reflective optical element generally transmits the laser or BBL beam.
