Abstract
A biopsy device includes a manifold having a first passageway, a second passageway, and a third passageway. A fluid cartridge is operably coupled to the manifold and provides fluid to the manifold. A cutting mechanism is operably coupled to the manifold, and includes a cutting cannula, a sample notch cannula, and a sample storage area. A handheld member is slidably coupled to the manifold, and manual translation of the handheld member directs fluid between the first passageway, the second passageway, and the third passageway.
Claims20
A biopsy device, comprising:
- a manifold having a first passageway, a second passageway, and a third passageway;
- a fluid cartridge operably coupled to the manifold for providing fluid to the manifold;
- a cutting mechanism operably coupled to the manifold, the cutting mechanism comprising a cutting cannula, a sample notch, and a sample storage area;
- and
- a handheld member slidably coupled to the manifold, wherein manual translation of the handheld member directs fluid between the first passageway, the second passageway, and the third passageway.
A biopsy device, comprising:
- a manifold having a first passageway, a second passageway, and a third passageway;
- a fluid cartridge operably coupled to the manifold for providing fluid to the manifold;
- a cutting mechanism operably coupled to the manifold, the cutting mechanism comprising a cutting cannula, a sample notch, and a sample storage area;
- and
- a handheld member slidably coupled to the manifold, such that manual translation of the handheld member directs fluid between the first passageway, the second passageway, and the third passageway;
- wherein the first passageway of the manifold comprises a first valve for creating a vacuum to introduce a tissue sample into the sample notch, the second passageway of the manifold comprises a second valve for maintaining the vacuum in the sample notch and pushing the cutting cannula forward across the tissue sample, and the third passageway comprises a pneumatic cylinder which retracts the cutting mechanism and transports the tissue sample to the sample storage area.
A method of operating a biopsy device, comprising:
- providing fluid to a manifold of the biopsy device using a fluid cartridge;
- manually sliding a handheld member of the biopsy device to a first position in the manifold;
- creating a vacuum for capturing a tissue sample in the biopsy device;
- manually sliding the handheld member of the biopsy device to a second position in the manifold;
- pushing a cutting mechanism of the biopsy device across the tissue sample;
- manually sliding the handheld member of the biopsy device to a third position;
- retracting the cutting mechanism of the biopsy device such that the tissue sample is returned to a sample acquisition area of the biopsy device;
- and
- returning the handheld member of the biopsy device to the first position.
