Abstract
An anatomical specimen collection device and system enabling a higher capacity, extended filtering capability and easy removal of the specimen while avoiding blockage or clogging. The anatomical specimen collection device includes a removable flexible nozzle with a distal end configured for mating with a variety of suction instruments and a removable axial filter element surrounded by a negative pressure environment.
Claims16
An anatomical specimen collection device comprising:
- a hollow body extending along a longitudinal axis;
- the body including:
- a first opening in a proximal end thereof, the first opening surrounded by a flange extending in the proximal direction configured to provide a sealed connection to a suction source;
- the first opening in fluid communication with an internal space;
- a second opening at a distal end thereof;
- and
- two opposed wall extensions extending in the distal direction from the distal end, wherein the two opposed wall extensions are spaced apart from each other to form a first annular gap and second annual gap between the two opposed wall extensions,
- a pair of raised protrusions positioned adjacent the two opposed wall extensions on an outer surface of the body,
- a filter mounted in the body between the first opening and the second opening:
- the filter including:
- a closed proximal end portion;
- an open distal end portion including a cylindrical support element, the cylindrical support element having an outer diameter larger than that of the proximal end;
- wherein the cylindrical support element is received between and entirely within the two opposed wall extensions such that the cylindrical support element does not extend distally or laterally beyond the two opposed wall extensions, is accessible via the first annular gap and the second annular gap;
- and
- a mesh portion extending longitudinally between the closed proximal end portion and the open distal end portion defining an interior space aligned with the longitudinal axis;
- and
- a flexible nozzle removably connected to the distal end of the body, the flexible nozzle tapering from a proximal end thereof in contact with the body to a distal end thereof, the distal end including a suction opening that is in fluid communication with the interior space of the filter and the first opening in the proximal end of the body such that anatomical specimen material is drawn into the suction opening, through the filter and the first opening when the first opening is connected to suction,
- wherein an inner surface of the proximal end of the nozzle includes a pair of channels positioned and configured to receive the pair of raised protrusions of the body to secure the nozzle to the body.

An anatomical specimen collection system comprises:
- a suction tube configured for connection to a suction supply;
- and
- an anatomical specimen collection device in fluid communication with the section tube, the anatomical specimen collection device including:
- a hollow body extending along a longitudinal axis;
- the body including:
- a first opening in a proximal end thereof, the first opening surrounded by a flange extending in the proximal direction configured to provide a sealed connection to the suction tube;
- the first opening in fluid communication with an internal space;
- a second opening at a distal end thereof;
- and
- two opposed wall extensions extending in the distal direction, wherein the two opposed wall extensions are spaced apart from each other to form a first annular gap and second annual gap between the two opposed wall extensions;
- a pair of raised protrusions positioned adjacent the two opposed wall extensions on an outer surface of the body;
- a cylindrical filter mounted in the body between the first opening and the second opening:
- the cylindrical filter including:
- a closed proximal end portion;
- an open distal end portion including a cylindrical support element;
- wherein the cylindrical support element is received between and entirely within the two opposed wall extensions such that the cylindrical support element does not extend distally or laterally beyond the two opposed wall extensions and is accessible via the first annular gap and the second annular gap;
- and
- a mesh portion extending longitudinally between the closed proximal end portion and the open distal end portion defining a cylindrical interior space aligned with the longitudinal axis,
- wherein a gap is provided between an outer surface of the filter and an inner surface of the body wherein the gap has a uniform shape between the cylindrical support element and the closed proximal end portion such that a space between the outer surface of the filter and the inner surface of the body is substantially uniform in size;
- and
- a flexible nozzle removably connected to the distal end of the body, the flexible nozzle tapering from a proximal end thereof in contact with the body to a distal end thereof, the distal end including a suction opening that is in fluid communication with the interior space of the filter and the first opening in the proximal end of the body such that anatomical specimen material is drawn into the suction opening, through the filter and the first opening when suction is applied via the suction tube through the first opening, wherein the suction tube is connected to the proximal end of the body,
- wherein an inner surface of the proximal end of the nozzle includes a pair of channels positioned and configured to receive the pair of raised protrusions of the body to secure the nozzle to the body.
