INSUFFLATING OPTICAL SURGICAL INSTRUMENTS
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.
