Laparoscopic port
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.
1. A laparoscopic port comprising:
a tubular member comprising a proximal end and a distal end and a lumen extending therebetween;
a valve provided in the lumen and configured to prevent pressurized gas flow from the distal end to the proximal end in a closed configuration in the absence of an artifact;
a sensor configured to sense a parameter associated with the artifact when in the lumen; and
an actuator configured to open the valve from the closed configuration based on the sensed parameter.
2. The laparoscopic port of claim 1 , wherein the sensor is provided in the lumen.
3. The laparoscopic port of claim 1 , wherein the sensor is positioned on the artifact.
4. The laparoscopic port of claim 1 , wherein the sensor and the actuator are in wireless communication.
5. The laparoscopic port of claim 1 , wherein the valve is normally closed.
6. The laparoscopic port of claim 1 , wherein the valve is closed by the actuator on demand.
7. The laparoscopic port of claim 1 , wherein the sensor is adapted to command the actuator to open the valve when the artifact is positioned in a predetermined sensing range and/or in line of sight.
8. The laparoscopic port of claim 1 , wherein the sensor includes at least one of a mechanical sensor, a probe, an antenna, an electric sensor, a proximity sensor, a magnetic sensor, a pressure sensor, an optical sensor, and an acoustic sensor.
9. The laparoscopic port of claim 1 , further comprising a centering mechanism adapted to align the artifact.
10. The laparoscopic port of claim 9 , wherein the centering mechanism aligns the artifact concentric with an axis of the lumen.
11. The laparoscopic port of claim 9 , wherein the centering mechanism is provided on the artifact.
12. The laparoscopic port of claim 9 , wherein the centering mechanism is provided in the lumen and distal to the sensor.
13. The laparoscopic port of claim 9 , wherein the centering mechanism comprises an expandable portion.
14. The laparoscopic port of claim 13 , wherein the expandable portion is inflatable.
15. A method of actuating a valve of a laparoscopic port, the valve being in a lumen of a tubular member of the laparoscopic port, the method comprising:
sensing a parameter associated with an artifact in the lumen; and
opening the valve from a closed configuration with an actuator based on the sensed parameter, the valve preventing pressurized gas flow from a distal end of the tubular member to a proximal end of the tubular member in the closed configuration in the absence of the artifact.
