Laparoscopic hysterectomy specimen retrieval device
View Patent ↗A laparoscopic assisted vaginal hysterectomy specimen retrieval device provides a plug assembly that rides along an outer circumference of the introducer tube. The plug assembly is moveable between a locked condition and an unlocked condition. A distal end of the plug assembly provides a seal portion dimensioned and adapted to engage a vaginal cavity in a sealed engagement, whereat a user may form a locked condition to prevent insufflated gas from escaping the vaginal cavity while the retrieval bag of the laparoscopic assisted vaginal hysterectomy specimen retrieval device is deployed, utilized, and retracted into the introducer tube.
1 . A laparoscopic assisted vaginal hysterectomy specimen retrieval device, comprising:
an introducer tube having a retrieval bag adjacent its distal end;
a plug assembly that slides along an outer circumference of the introducer tube, the plug assembly being moveable between a locked condition and an unlocked condition enabling sliding along said outer circumference; and
a seal portion disposed along a distal end of the plug assembly dimensioned and adapted to occlude a vaginal cavity of a laparoscopic patient in a sealed engagement,
whereby the sealed engagement prevents insufflated gas from escaping the vaginal cavity while the laparoscopic assisted vaginal hysterectomy specimen retrieval device is utilized, wherein the plug assembly further comprises a clamping apparatus for forming the locked condition, and wherein the plug assembly further comprises an actuator member for moving between the locked and unlocked conditions.
2 . The laparoscopic assisted vaginal hysterectomy specimen retrieval device of claim 1 , wherein the actuator member is disposed along a proximal end of the plug assembly.
3 . The laparoscopic assisted vaginal hysterectomy specimen retrieval device of claim 2 , wherein the seal portion has a tapered profile facilitating the sealed engagement.
4 . The laparoscopic assisted vaginal hysterectomy specimen retrieval device of claim 3 , wherein the tapered profile is defined, in part, by two or more rounded flanges of different diameters.
5 . The laparoscopic assisted vaginal hysterectomy specimen retrieval device of claim 4 , further comprising a retrieval bag movable between a retracted position and a deployed position relative to the introducer tube.
