"Vacuum Shell for Robotic Surgery of Soft Tissue" in Patent Application Approval Process

September 4, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventor Ghaderi, Bahram (St. Charles, IL), filed on February 4, 2014, was made available online on August 21, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application has not been assigned to a company or institution.

The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to robotic surgery of soft tissue and, in particular, to devices for facilitating manipulation of soft tissues during surgical procedures.

"Mastectomy, breast reduction, breast reconstruction and breast enhancement procedures have become commonplace. In typical surgical techniques for breast enhancement, a silicone or saline filled implant device is inserted into the breast after an incision in locations such as the inframammary fold, or periareolar area. In such procedures, it is often necessary for the surgeon to manipulate the soft tissue of the breast and hold it in place to allow easier access to the skin for a clean incision and placement of the breast implant. This minimizes scarring, provides better aesthetic appeal, and prevents postsurgical complications.

"It is theoretically possible for robotic devices, such as those sold under the daVinci.RTM. trademark (Intuitive Surgical, Inc.--Sunnyvale, Calif.), to execute many breast enhancement procedures. However, it is difficult for a surgeon to operate a robotic surgery apparatus, and also to maintain soft tissues, such as breast tissue, in such a manner to provide the best incision as provided above. It would be desirable to have a device that could, in an automated way, allow manipulation of soft tissues in a surgical procedure."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventor's summary information for this patent application: "A device is provided for expanding and manipulating soft tissue during surgery, that comprises a shell capable of withstanding negative pressure. The shell has a soft, flexible rim disposed around the peripheral edges of the shell for sealing to the skin of a patient to isolate a space between the shell and a surgical area. The shell also has one or more instrument ports for allowing resealable entry of surgical instruments, and a vacuum port that allows negative pressure to be applied to the space. The device is designed to be fit over the surgical area of operation to create a space around the surgical area, and with the vacuum port in communication with a vacuum pump so as to provide negative pressure to the surgical area through the shell in order to expand soft tissue to expose the skin to surgical instruments, and to assist in holding soft tissue in place.

"In another embodiment of the invention, the vacuum port comprises a network of sealed slots disposed over the shell, that can be reclosably pierced by a vacuum hose assembly to slide along the slots move around on the surface of the shell. The vacuum hose assembly contains a sliding vacuum hose that can be extended or retracted into the shell to further provide localized negative pressure to soft tissue.

BRIEF DESCRIPTION OF THE DRAWINGS

"FIG. 1 is a front elevation view of a vacuum shell apparatus, showing how it would be mounted in a breast augmentation or other surgical procedure.

"FIG. 2 is a side section, detail view of a rim portion of the vacuum shell apparatus of FIG. 1.

"FIG. 3 is a top view of an alternative embodiment of a vacuum shell apparatus.

"FIG. 4 is a side section, detail view of the embodiment of a vacuum shell apparatus of FIG. 3, showing the vacuum hose assembly.

"FIG. 5A is a front elevation view of yet another embodiment of a vacuum shell apparatus having moveable negative pressure points, showing how it would be mounted in a breast augmentation or other surgical procedure.

"FIG. 5B is a side section view of the embodiment of a vacuum shell apparatus of FIG. 5A.

"FIG. 6 is a side section, detail view of the embodiment of a vacuum shell apparatus of FIG. 5B, showing a moveable negative pressure point positioned over a breast.

"FIG. 7A is a top perspective view of the embodiment of the vacuum shell apparatus of FIG. 5A.

"FIG. 7B is a bottom perspective view of the embodiment of a vacuum shell apparatus of FIG. 7A.

"FIG. 8 is a top perspective view of the embodiment of the vacuum shell apparatus of FIG. 7A, showing how it would be mounted in a breast augmentation or other surgical procedure."
