摘要：
An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed. The instrument comprises a shaft having an insufflation channel extending 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 is at the distal end and a vent hole is formed in the tip being in connection with the insufflation channel and adapted to expel fluid under pressure to insufflate the abdominal region. The tip is formed of a transparent material to facilitate visualization of the abdominal wall and 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.
