    Abstract: An endoscopic tissue resecting system that includes a reciprocating rotary surgical instrument for cutting tissue that includes a planetary gear assembly to vary rotational speed. A method of cutting and detaching tissue includes positioning an outer member such that tissue is located within a window in the outer member, engaging the tissue with an inner member, and simultaneously rotating at an increased speed relative to a rotary driver and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut and detach the tissue.

  • Patent number: 9603617
    Abstract: Liquid is ejected in a pulse-like manner from a nozzle provided at the distal end of a liquid ejection pipe. When the liquid is ejected, moving speed of the nozzle is detected. A driving frequency of a piezoelectric element is increased when the moving speed increase. The driving frequency is reduced when the moving speed decreases. Consequently, it is possible to prevent the number of times the liquid is ejected per unit length from changing according to the moving speed of the nozzle. Therefore, it is possible to excise a biological tissue at stable excision depth.

  • Patent number: 8764680
    Abstract: A biopsy device includes a body, a needle, and a cutter. A motor is operable to both move the cutter relative to the needle and actuate a needle firing assembly to retract and fire the needle relative to the body. The biopsy device also includes a needle rotation assembly that is configured to substantially prevent rotation of the needle about the longitudinal axis when the needle is in a proximal position yet permit rotation of the needle about the longitudinal axis when the needle is in a distal position. A valve assembly of the biopsy device includes a slider that selectively couples a secondary lumen in the needle with either atmospheric air or saline based on the longitudinal position of the slider. The cutter passes through the slider.

    Abstract: A biopsy apparatus includes a driver assembly and a disposable biopsy probe assembly for releasable attachment to the driver assembly. The driver assembly includes a first vacuum path having a first one-way valve configured and arranged to permit a negative pressure fluid flow toward a vacuum source and to prevent a positive pressure fluid flow away from the vacuum source. The disposable biopsy probe assembly includes a second vacuum path having a second one-way valve configured and arranged to permit the negative pressure fluid flow from a sample basket and to redundantly prevent the positive pressure fluid flow toward the sample basket. A fluid management tank is fluidically interposed in the second vacuum path between the first end and the second end. The fluid management tank includes a filter arrangement to prevent a flow of residual biopsy biological material from the sample basket to the vacuum source.

  • Patent number: 8657841
    Abstract: A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. The inner cannula includes a hinge between a body section and a cutting section that allows the cutting section to pivot when the inner cannula reciprocates within the outer cannula. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. The inner cannula and the outer cannula define an annular space between the inner cannula and the outer cannula, and a seal is provided at the proximal end of the annular space. The seal is preferably a thixotropic, semi-solid material such as a high vacuum, halogenated polymeric grease. The device may also include an inner cannula stop position control for selectively controlling the position of the inner cannula when it is at rest.
