  • Surgical suction device that uses positive pressure gas
    Patent number: 10821212
    Abstract: A surgical suction device that uses positive pressure gas is shown and described. The surgical suction device includes an air amplifier. The air amplifier includes a structure defining a generally cylindrical cavity having a first opening at a first end and a second opening at a second end. The cylindrical cavity is defined by an inner wall of the cavity. The air amplifier includes an annular opening in the inner wall near the first end. The annular opening defines a jet opening adapted to allow a pressurized gas to flow out of the annular opening such that a low pressure region is produced at the first end and an amplified flow is produced at the second end. The annular opening is further configured such that the pressurized gas enters the cavity at an angle with respect to the inner wall of the cavity that is towards the second end.

  • Articulating steerable clip applier for laparoscopic procedures
    Patent number: 10792040
    Abstract: A long articulating steerable clip applier affixed to a user-operated handle. A surgical jaw assembly is attached to the other end of the clip applier. The clip applier is composed of articulating phalanges that are connected end to end by pivoting links and capable of angulations relative to one another when subjected to a tensile force. Each phalange has opposing s-shaped exterior grooves that form two continuous spiral-shaped channels for holding tension wires once the phalanges are assembled. Multiple tension wires are attached to opposite ends of adjacent phalanges. When each wire is pulled, this tensile force causes the phalanges to pivot at equivalent angles with each other. As each individual phalange pivots by an equivalent angle, the sum of these angles causes the free end of the clip applier to pivot by a large angle or a cascading actuation effect.

  • SURGICAL CLIP FOR LAPAROSCOPIC PROCEDURES
    Publication number: 20200297348
    Abstract: A surgical clip for a clip applier to ligate vessels. The clip contains two opposing legs connected in parallel by an apex to form a U-shape. Each leg has an outer surface with a half-round cross-sectional configuration for minimizing tissue damage by preventing clip scissoring during ligation. Each leg has an inner surface with a flat central surface, two concave grooves on opposing sides of the central surface, and two convex ridges on opposing sides of each groove. As a vessel is ligated, vessel tissue moves into the concave grooves while remaining frictionally engaged by the compressive forces applied by the central surfaces and convex ridges of leg so that the clip does not move on the vessel. The edges of the grooves and the edges of the ridges of each leg are rounded to prevent any cutting of the ligated vessel.

  • Meniscal transplant system
    Patent number: 10736755
    Abstract: A workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.
