Abstract
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 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 translucent or transparent to facilitate visualization of 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.
