  • SINGLE PORT ACCESS SYSTEM
    Publication number: 20130303857
    Abstract: Embodiments of a surgical access system useful for single or limited port procedures comprise a trocar comprising a fixation cannula, a retractor, and a gel cap removably coupled to the retractor. The gel cap comprises a gel pad that acts as an artificial body wall, through which instruments may be inserted into a body cavity, either directly or through one or more trocars. The fixation cannula comprises a retainer and a bolster, which together, capture the artificial body wall therebetween, thereby fixing the trocar thereto. The gel pad permits flexible instrument placement, as well as translational and angular degrees of freedom for the instruments while maintaining a gas tight seal.

  • Electrosurgical system
    Patent number: 8579894
    Abstract: An electrosurgical tool can be used to fuse tissue. The electrosurgical tool can include a jaw assembly, an elongate shaft, and a handle assembly. Actuation of the handle assembly can actuate the jaw assembly. The elongate shaft can be rotatable without disrupting electrical connection to the jaw assembly. The electrosurgical tool can include a cutting blade to separate fused tissue.

  • Tissue fusion/welder apparatus and method
    Patent number: 8551089
    Abstract: A tissue welding apparatus is adapted to fuse a first piece of tissue to a second piece of tissue which are disposed in a surface proximate relationship. An elongate shaft carries a first jaw, and a second opposing jaw moveable relative to the first jaw. At least one penetrating member is carried by the first jaw and moveable relative to the second jaw to create a channel through the first piece of material and the second piece of material. A source of heat is coupled to the penetrating member for denaturing the tissue defining the channel. This denatured tissue forms a column binding the first piece of tissue to the second piece of tissue. A chemical agent can be carried to the tissue with the penetrating member.

  • WOUND RETRACTOR WITH GEL CAP
    Publication number: 20120330105
    Abstract: An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop positioned therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.

  • BLADELESS OPTICAL OBTURATOR
    Publication number: 20120316595
    Abstract: A surgical access device comprising a tissue separating obturator suitable for connection with a cannula is disclosed. The obturator includes an elongate shaft having a transparent distal tip. The elongate shaft extends along a longitudinal axis and defines a lumen. The transparent distal tip has a tapered configuration and includes an inner surface and an outer surface adapted for penetrating tissue. The lumen is sized and configured to receive an optical instrument such as a laparoscope. The surgical access device further includes a scope lock at the proximal end of the shaft portion. The lock includes a multi-fingered collet coaxial with the lumen. The inner diameter of the collet is smaller than an outer diameter of the optical instrument and the fingers of the collet provide frictional engagement with the outer diameter of the optical instrument that is inserted into the lumen of the obturator.

  • PLEATED TROCAR SHIELD
    Publication number: 20120316501
    Abstract: A surgical access device or trocar defines an access channel for instruments extending from a proximal end to the distal end thereof. The trocar comprises a cannula and a seal assembly disposed at the proximal end of the cannula. The seal assembly comprises a first or zero seal, a second or instrument seal, and a trocar shield disposed proximally of the first seal and the second seal. The first seal seals the access channel in the absence of an instrument extending therethrough. The second seal seals the access channel in the presence of an instrument extending therethrough. The trocar shield protects the first seal and second seal from damage as an instrument is advanced through the access channel. The trocar shield comprises an open proximal end and a tapered distal end comprising a plurality of longitudinal pleats, converging in an opening.
