  • Patent number: 10271836
    Abstract: An endoscopic stitching device includes an actuation shaft, a tool assembly, and a drive assembly. The tool assembly includes a suture needle and a pair of jaws transitionable between open and closed positions. Each jaw includes a needle engaging blade slidably supported thereon. Each needle engaging blade is transitionable between an extended position in which the needle engaging blade engages the suture needle and a retracted position in which the needle engaging blade is disengaged from the suture needle. The drive assembly includes first, second, and third electrical actuators. The first actuator is operatively coupled with the actuation shaft to cause axial displacement of the actuation shaft. The axial displacement of the actuation shaft causes opening and closing of the pair of jaws. The second and third actuators are operatively coupled with the needle engaging blades to provide axial displacement of the needle engaging blades.

  • Patent number: 10258463
    Abstract: A novel phakic intraocular lens implantation without viscoelastics and an instrument thereof. The special designed instrument is employed to achieve a purpose of maintaining an anterior chamber only with a perfusion liquid in the surgery, so as to get rid of the influence of the viscoelastics completely. The viscoelastics are not used, so that there is no need to inject the viscoelastics or remove the viscoelastics as in traditional methods, the surgery time is shortened such that total time of surgical procedures from incision construction to incision hydration can be reduced to only 1˜3 minutes, and viscoelastic-related complications, such as postoperative high intraocular pressure and lens opacity, are completely avoided.

  • Patent number: 10213287
    Abstract: A blood filter device having occlusion-resistant characteristics. The occlusion-resistant characteristics decrease the likelihood of the filter being blocked by thrombi. The filter device (252a, 252b) includes at least one anchor portion (42) for anchoring the filter device within one or more arteries (354a, 354b), and a filter portion (98) for filtering thrombi from the blood entering the artery. In some embodiments, an anchor portion is capped with a filter cap. In various embodiments, the filter cap is protrudes into the aorta to promote occlusion resistance. In one embodiment, the device can be modified in situ to re-establish normal blood flow through the artery in the unlikely case of thrombotic or other blockage of the filter. In some embodiments, a bypass opening or open channel defining an access port is provided to accommodate passage of surgical instruments into the artery and to enable blood flow to bypass the filter should the filter become heavily occluded.
