  • Patent number: 9125641
    Abstract: A ratchet assembly for multi-dimensional movement and placement of a retractor blade includes a retractor blade holder, a housing member, a rotating indexer and a self-retaining locking mechanism. The retractor blade holder is shaped and dimensioned to receive a stem of a retractor blade and includes a locking mechanism that enables selective lateral adjustment of the retractor blade relative to the retractor blade holder. The retractor blade holder is mated to the housing member and is vertically pivotable with respect to the housing member to enable selective vertical pivoting adjustment of the retractor blade relative to the housing member. The rotating indexer is mated to the housing member, and the housing member is rotatable with respect to the rotating indexer so that the retractor blade holder, the housing member and the retractor blade are able to selectively rotate about the longitudinal axis of the rotating indexer.

  • Publication number: 20100210913
    Abstract: A disposable cover for a retractor of a self-retaining retractor system has an elastic sheath that can be easily placed and removed by elastically engaging the blade and a disposable pad attached on the elastic sheath. The elastic sheath can be an open cylinder (band shaped) or closed at one end (sock shaped) and is sized to cover a majority of the different size and shaped retractor blades. The elastic sheath retains the disposable pad on the blade by elastic compressive force. A single elastic sheath must be elastic enough to accommodate multiple sized blades and retain them in a fixed position while the blade is approximately vertically disposed within patient. The elastic sheath can be made from latex, nylon or any other surgical grade elastic or elastic type product.
