Orthohelix Surgical Designs, Inc. - Akron OH

International Classification:

A61B 17/04

US Classification:

606232, 606 60, 606 72, 606 73, 606218, 411395, 470 6, 470 8, 470 10, 470 14, 470 19

Abstract:

The invention relates to a tissue anchor which is an open helix of biocompatible material having a slope of from 0. 5 to 10 turns per centimeter, a length from 3 to 75 millimeters, a diameter of from 1. 5 to 11 millimeters, and an aspect ratio of from about 3 to about 5 to 1. The anchor can have a head which is capable of securing or clamping tissue together, such as holding a suture to secure a ligament or tendon to bone. The anchor can also have a head which causes an inward, compressive loading for use in fastening bone to bone, orthopedic plates to bone, or cartilage to bone. The head may be an integral member and may include a self-reinforcing wedge which joins the helix to the head. Further, the elongate member, or filament that forms the helix may have a tapering diameter along its length.

International Classification:

B25B 23/10
A61B 17/86

US Classification:

81451, 606 73

Abstract:

The present invention relates to an orthopedic screw and a corresponding screw driver wherein the screw has a torque driving head with a rounded side a spherical wall for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a cancellous thread. The threaded portion has a major diameter defined by a spiraling thread and a minor diameter. The head is joined to the threaded portion by an area of from about 2 to about 6 turns of the thread along the longitudinal axis in which the minor diameter tapers by an angle of from about 4 to about 12 and the major diameter of the screw remaining substantially the same. The screw includes a multilobe torque driving recess joined to a cylindrical recess that corresponds to a cylindrical post on the torque driver so as to form a press fit which acts to self-center the screw, to help avoid stripping of the screw/driver interface and to hold the screw in place on the torque driver prior to implantation.

US Classification:

606284, 606280, 606286, 606312

Abstract:

The present invention relates to an orthopedic plate and screw system and instruments for surgical fixation of a small bone or bones. The plate facilitates three dimensional contouring to provide for a variety of applications and to accommodate individual variation in bone shape. The plate has a modified x shape including a central trunk portion including one or more screw holes along a longitudinal axis and a set of divergent upper and an oppositely extending set of divergent lower arms, each arm including screw holes which are placed at a radially equal distance but which diverging asymmetrically from the longitudinal axis relative to its paired upper or lower mate. The screws of the system are self-starting, self-tapping screws including the option of partial or full cannulation.
