Abstract
A laparoscopic port is disclosed which includes a tubular member comprising a proximal end and a distal end and a lumen extending there between. At least one seal member provided in the lumen adapted to prevent pressurized gas flow from the distal end to the proximal end of the tubular member. The laparoscopic port further includes a shielding trigger positioned distal to the seal member in the lumen, the shielding trigger is shaped so as at least a proximal portion of the shielding trigger has a narrowing cross-section that extends towards the seal member, the proximal portion is adapted to actuate a reversibly opening and protection of the seal member upon a proximally projected pressure from a distal end of an artifact.
Claims22
A laparoscopic port, comprising:
- a tubular member comprising a proximal end and a distal end and a lumen extending therebetween;
- at least one seal member provided in said lumen adapted to prevent pressurized gas flow from said distal end to said proximal end of said tubular member;
- and
- a shielding trigger positioned distal to said seal member in said lumen, said shielding trigger being shaped so as at least a proximal portion of said shielding trigger has a narrowing cross-section that extends towards said seal member, said proximal portion is adapted to actuate a reversible opening and protection of said seal member upon a proximally projected pressure from a distal end of an artifact.
A method of opening and protecting a seal member in a laparoscopic port from being damaged by an artifact, said method comprising:
- providing a shielding trigger distally to said sealing member, wherein a proximal end of said shielding trigger is laterally extendable;
- and
- projecting a proximal pressure by a distal end of said artifact against a distal side of said shielding trigger, whereby said proximal end of said shielding trigger extends laterally opening and protecting said seal member.
