Single port device having integral filter/vent
View Patent ↗A laparoscopic port device includes a compliant port body having a distal and proximal end having a lumen extending therethrough. The lumen has a filtering agent configured to retain or treat particulate contaminates present in insufflation gases. The laparoscopic port device further includes a valve operatively connected with the lumen to selectively regulate flow of the insufflation gases therethrough.
1. A laparoscopic port device comprising;
a compliant port body having a distal and a proximal end;
an integral vent that traverses the compliant port body defining a lumen in fluid communication between the distal and proximal ends of the compliant port body, wherein the integral vent is configured to allow direct flow through the vent from the distal end through the proximal end; and
a filtering agent disposed in the lumen, the filtering agent configured to retain or treat particulate contaminates present in insufflation gases.
2. The laparoscopic port device of claim 1 , further comprising a second lumen extending through the port body configured to allow surgical instruments to traverse the port body.
3. The laparoscopic port device of claim 1 , wherein the compliant body is formed from a foam material.
4. The laparoscopic port device of claim 1 , further comprising a plurality of additional lumens extending through the port body configured to allow a plurality of surgical instruments to simultaneously traverse the port body.
5. The laparoscopic port device of claim 1 , further comprising a valve operatively connected with the lumen occupied by the filtering agent.
6. The laparoscopic port device of claim 5 , wherein the valve has a dynamically adjustable opening therein.
7. The laparoscopic port device of claim 5 , wherein the valve selectively regulates flow of the insufflation gases through the lumen.
8. The laparoscopic port device of claim 5 , wherein the valve is operated manually.
9. The laparoscopic port device of claim 5 , wherein the valve is a check valve.
10. The laparoscopic port device of claim 5 , wherein the valve is an electrically operated valve.
11. The laparoscopic port device of claim 10 , wherein the valve is operatively connected with a control unit.
12. The laparoscopic port device of claim 11 , wherein the control unit is configured to analyze images sent by an endoscope.
13. The laparoscopic port device of claim 11 , wherein the control unit is configured to regulate output rate of the insufflation gases.
14. The laparoscopic port device of claim 1 , wherein the lumen is dimensioned to provide an output flow rate of insufflation gas that is less than an input flow rate of insufflation gas at a first pressure thereby allowing pressure of a body cavity to build, wherein the lumen is dimensioned such that the output flow rate of insufflation gas is equal to the input flow rate of insufflation gas at a second pressure thereby allowing pressure of a body cavity to be held at a constant value.
15. A laparoscopic port device comprising;
a compliant port body having a distal end and a proximal end; and
a filtering agent integrally formed in the port body and establishing fluid communication between the distal and proximal ends of the compliant port body, wherein the filtering agent allows direct flow through the vent from the distal end through the proximal end, the filtering agent configured to retain or treat particulate contaminates present in insufflation gases.
16. The laparoscopic port device of claim 15 , further comprising a lumen extending through the port body configured to allow surgical instruments to traverse the port body.
17. The laparoscopic port device of claim 15 , wherein the compliant body is formed from a foam material.
18. The laparoscopic port device of claim 15 , further comprising a plurality of additional lumen extending through the port body configured to allow a plurality of surgical instruments to simultaneously traverse the port body.
