    摘要： The invention is directed to a trocar assembly having a channel defined along an elongate axis, the trocar assembly being adapted to receive a surgical instrument, the trocar assembly comprising a septum seal disposed in the channel including a seal tip having a proximal facing surface, the seal tip including portions defining an orifice; and a septum shield including a tubular member having a proximal end and a distal end, and a plurality of blades or leaflets protruding distally from the distal end of the tubular member, the septum shield being placed inside the septum seal such that the blades engage the proximal facing surface of the seal tip. The trocar assembly may further comprise a zero closure seal such as a double duckbill valve disposed in the channel outside of the septum seal. The septum shield operates to reduce the drag force and to minimize axial movement of the septum shield and the instrument during insertion and removal of the instrument through the septum seal. The septum shield may be formed from a rigid plastic material, and the septum seal may be formed of an elastomeric material. The blades or leaflets may overlap or offset one another. The orifice may be expandable to accommodate the instrument having a diameter of about 5-15 mm. The blades or leaflets have distal tips that glide or roll against the instrument during placement of the instrument. The distal tips may comprise of a combination of material, durometer and shield geometry to control the behavior of the septum shield. The trocar assembly may further comprise a second septum shield disposed outside of the septum seal.

    摘要： An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed comprising a shaft having an insufflation channel extending along an axis between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end, a tip at the distal end of the shaft, and at least one vent hole formed at the tip or the shaft being in connection with the insufflation channel and being adapted to expel the fluid under pressure to insufflate the abdominal region. At least one of the tip and the shaft is formed of a translucent or transparent material such as polycarbonate to facilitate visualization of the abdominal wall and the abdominal region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel. The tip may be blunt, the shaft and the tip may be integrally formed, and the vent hole may be of any geometric shape including round, oval, square and rectangular. The blunt tip may further comprise a marker to indicate penetration of the abdominal wall. In another aspect, the tip may be sharp, pointed or bladed to facilitate penetration of body tissue.

    摘要： 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 placed 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.
