  • Patent number: 11134936
    Abstract: A spine retractor provides lateral access to the spine for distracting soft tissue and psoas muscle for spinal fusion procedures utilizing position controllable blades. The retractor allows concerted linear distraction of two lateral blades and separate linear distraction of one medial blade. Individual angulation assemblies associated with each blade provides separately controllable angulation. Handles attached to the two lateral blades control their distraction while a medial knob controls medial blade distraction. An expansion knob associated with each handle provides individually precise distraction of its associated blade. Each angulation assembly comprises an angulation knob that threads into a distal arm of a blade holder assembly and is received into a spherical ball seated in a spherical pocket in a mating proximal arm of the blade holder assembly. Torque applied to the spherical ball by the angulation knob causes distal arm angulation relative to the proximal.

  • Patent number: 10537470
    Abstract: A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a center opening that provides a wide view of the ocular chamber during the procedure.

  • Patent number: 10478169
    Abstract: Systems, devices and methods related to retractor systems that retract tissue to allow access to a surgical site are described. The retractor systems can include a first rotatable arm attachable to a first blade, a second rotatable arm attachable to a second blade and a third linearly translatable arm attachable to a third blade. An attachment mechanism that is attachable to a fourth blade can be removably coupled to a mount on the frame. The retractors systems can also include two blade systems whereby when the retractor is in a closed configuration, the two blades form an oval opening.

  • Patent number: 10426450
    Abstract: A retractor for use in surgical operations comprises a pair of blade assemblies. In operation, the blade assemblies are initially in a closed position to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The retractor is adapted to rotate a first blade about a first axis and a second blade about a second axis. The retractor is adapted to move the pair of blade assemblies apart along a third axis. The retractor is adapted to pivot the first blade about a fourth axis and the second blade about a fifth axis. In some embodiments, a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed retractor is provided.

  • Patent number: 10398425
    Abstract: Disclosed herein are methods and devices for distracting adjacent vertebrae during surgical procedures for implanting spinal prostheses. In an exemplary embodiment, a distractor is disclosed that maintains the empty space between adjacent vertebrae following a discectomy, and that can removably mate with other surgical instruments, such as, for example, a filler bar, an implanting tool, or a funnel. In other embodiments of the present invention a distractor is disclosed having various features to assist in implanting a spinal prosthesis, such as, for example, an angled distal end and/or an expandable paddle. In another embodiment of the present invention, an articulating inserter is disclosed. Moreover, various implants and funnels are also disclosed herein.

  • Patent number: 10238450
    Abstract: A facet joint surgical tool for treating a facet joint synovial cyst includes rotatable members disposed side-by-side through a minimally invasive sheath and rotatable to reconfigure distal end portions between a facet joint penetration configuration with a tissue piercing tip and a facet joint retraction configuration. Facet joint synovial cysts located to an anterior side of the facet joint are treated by a posterior approach with access to the cyst through the facet joint retracted by the surgical tool. Facet joint synovial cysts located to a posterior side of the facet joint are treated by direct access from a posterior approach.
