Jaw Structure Patents (Class 606/207)
  • Patent number: 7615066
    Abstract: The invention provides an articulating mechanism useful, for example, for remote manipulation of various surgical instruments and diagnostic tools within, or to, regions of the body. Movement of segments at the proximal end of the mechanism results in a corresponding, relative movement of segments at the distal end of the mechanism. The proximal and distal segments are connected by a set of cables in such a fashion that each proximal segment forms a discrete pair with a distal segment. This configuration allows each segment pair to move independently of one another and also permits the articulating mechanism to undergo complex movements and adopt complex configurations.

Therefore, this atraumatic hemostatic clamp has a simple structure and can provide a reliable grasp without causing trauma to bodily vessels, thus solving the problem of the conventional hemostatic clamp that vessel trauma may be easily caused.

  • Publication number: 20080287957
    Abstract: A spinal implant insertion device is hereby provided. The device includes an insertion blade assembly having a set of opposed insertion blades wherein the assembly is adapted to slide from a retracted position to an extended position relative to an elongate shaft. In the extended position, a blades are adapted to be positioned above and below a portion of a spinal implant so as to shield the portion of the implant during delivery to an intervertebral space. The insertion blades assembly can also be modular so as to utilize a wide range of distinct insertion blades. Additionally, a method for delivering a spinal implant to an intervertebral space is herein provided. Like above, the method utilizes an insertion blade assembly adapted to slide along a shaft of a spinal implant insertion device.

  • Patent number: 7431723
    Abstract: A tool, system and method for separating connected orthopaedic components are disclosed. The system includes two orthopaedic components that are connected end to end. One of the orthopaedic components has a notch that receives a cam carried by the tool. The notch and cam are sized and shaped so that when the cam is turned, the cam forces the two components apart. The invention is particularly useful when Morse tapers are used to connect the components. The invention can be used with the modular orthopaedic implants as well as with modular trials used intraoperatively. The cam can be removably mounted on the tool.

    Abstract: A bone retractor that may be used as a femoral elevator. The bone retractor includes a clamp for attaching the bone retractor to an operating room bed rail, a post attached to the clamp via a hinged joint, a mount slidably attached to the post and a hook coupled to the mount which in turn is attached to the post. A shaft passes through the interior of the post and attaches to clamp. The clamp has a lower jaw and an upper jaw. An opening is formed in the lower jaw and an end of the shaft is engaged in the opening. The shaft has two sections with a universal joint connecting these two sections. The born retractor is attached to the operating room bed rail by applying clamp to the bed rail. With bone retractor attached to the bed rail, the post is lowered towards the wound. The hook is placed under the bone, and the bone exposed by holding the hook or the post and lifting the bone out of the wound.
