  • Patent number: 10595899
    Abstract: Automatic dilator devices for generating minimally invasive access apertures for surgical procedures or endoscopic surveillance. The automatic dilators comprise a number of spreader tubes nested one inside the other. The devices deploy automatically by means of coupled mechanical mechanisms which insert one spreader after the other distally into the patient's tissue. Each spreader moves distally into the tissue by means of a screwing action, by which rotation is converted into linear motion of the neighboring spreader, immediately external to it, by means of interaction between a helical thread form on a surface of a spreader being engaged by a section of thread, or by one or more protrusions on the opposing face of the next spreader external to the rotating spreader. Such a combination of helical thread and follower enables a rotatory mechanism to be used to deploy one nested spreader tube after the other, by continuous rotary motion.

  • Patent number: 10596034
    Abstract: A crushing tip dramatically increases a contact area between the crushing tip ultrasonic vibrated and a crystalline lens, compared to conventional crushing tips, and can efficiently crush and emulsify the crystalline lens. In the crushing tip, which is inserted into the crystalline lens of an eye of a patient at a time of an eye surgery for crushing, sucking, and discharging the crystalline lens by providing the ultrasonic vibrations, one or a plurality of partition walls is provided in such a way as to cross a through hole inside the through hole of a cylindrical tip main member. A tip of the partition wall may project from a tip of the tip main member, and a projecting portion may extend to an outer peripheral edge of the tip main member in a width direction as well.

  • Patent number: 10588780
    Abstract: Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a plunger and an injector body that includes an insertion depth guard and a nozzle extending therefrom. The insertion depth guard is disposed at a distal end of the injector body to limit a distance that the nozzle penetrates the eye. The intraocular lens injector may also include a biasing element configured to generate a counterforce to distal movement of the plunger through the injector rod. An example intraocular lens injector may include a biasing element to produce a counterforce that opposes advancement of the plunger through the injector body. The counterforce provides for a more continuous advancement of the plunger while reducing or substantially eliminating abrupt changes in the rate at which the plunger is advanced through the injector body.

  • Patent number: 10542966
    Abstract: A readily implantable knotless suture anchor that de-couples the angle of insertion of the anchor from the tissue passage step and other steps of conventional procedures. An anchor provides an internal locking mechanism configured such that: suture knots do not have to be tied; suture and tissue tension can be easily adjusted intraoperatively; and suture passage and tensioning can be done at a variety of positions and angles. A method includes: passing a first suture through a patient's tissue and then through a loop of a shuttle suture; pulling the free end of the shuttle suture until the first suture passes through an internal suture locking mechanism; applying tension in the first suture until adequate tension is achieved with respect to the tissue; automatically engaging an internal locking member; and securing the first suture against further relative movement with respect to the anchor.

  • Patent number: 10537320
    Abstract: An arthroscopic needle having partial cuts or serrations along one side of a circular, hollow needle shaft allows the needle to bend, or articulate, by drawing a pull strip bar, defined by a thin strip along the interior side closet to the serrations in the hollow shaft, for compressing along the cuts to draw uncut segments into closer arrangement for curving the needle in the direction of the compressed side. The selectively articulating, or “bendable” needle that curves in response to a rotating knob provides for insertion of surgical attachment anchors in difficult-to-reach areas of meniscal tissue. The disclosed articulating needle has the ability to bend and access more anterior and posterior zones of meniscal repairs than conventional rigid needle approaches.

  • Patent number: 10531892
    Abstract: The disclosure provides examples of a surgical needle for entering a joint space through tissue, such as the hip joint. The surgical needle includes a stylet movable within a hollow body. The hollow body has at one end, a tip of a bevel for cutting tissue and at another end, a feedback member providing a surgeon with tactile feedback. The stylet has at one end, a resistance reducing member that when positioned a preset distance from the bevel reduces the resistance of the surgical needle through tissue. At the other end of the stylet is a stylet hub. In some examples of the surgical needle, the stylet hub includes a proximal stop, stylet locking member and/or locking member. The surgical needle advantageously provides tactile feedback, reduces resistance, and minimizes or prevents damage to delicate structures.
