    摘要： A method of cutting breast tissue for removal may include a step of providing a tissue cutting device having an elongate cutting element, the cutting element being movable between a bowed position and a retracted position, the cutting element having a radially outer side and a radially inner side. The tissue cutting device may be introduced into a breast and the elongate cutting element may be moved to the bowed position. A power source may be coupled to the elongate cutting element; and the cutting element may be rotated after the moving step so that the cutting element cuts the breast tissue. The radially outer side of the cutting element may have a larger surface area for transmitting energy to cut the tissue than the radially inner side.

    摘要： A device for cutting and collecting a specimen from a mass of tissue may include a shaft, an integrated cut and collect assembly coupled to the shaft and an actuator. The shaft may define an opening and may include an outer surface that defines a trough adjacent the opening, the trough defining a ledge portion that is cut out of the shaft. The integrated cut and collect assembly may include an RF cutting portion and a collection portion that includes a flexible membrane, the collection portion being attached to the cutting portion, the integrated cut and collect assembly being configured to assume a retracted position at least partially within the opening such that part of the collection portion is disposed within the trough and in contact with the ledge portion and a selectable expanded position that extends through the opening and away from the shaft. The cutting portion may be configured to cut the specimen from the mass of tissue and the collection portion may be configured to collect the cut specimen and to isolate the cut specimen within the membrane. The trough may be configured to minimize contact of the cutting portion with the tissue to be cut as the cutting portion is becoming fully energized in the retracted position. The actuator may be coupled to the integrated assembly such that operation of the actuator causes a deployment of the integrated assembly from the retracted position to the selectable expanded position.

    摘要翻译： 用于从大量组织切割和收集试样的装置可以包括轴，与轴连接的集成切割和收集组件和致动器。 轴可以限定开口并且可以包括限定靠近开口的槽的外表面，所述槽限定从轴切出的凸缘部分。 集成的切割和收集组件可以包括RF切割部分和收集部分，其包括柔性膜，收集部分附接到切割部分，集成切割和收集组件被配置为呈现至少部分地在 开口使得收集部分的一部分设置在槽内并与凸缘部分接触，并且可选择的扩展位置延伸穿过开口并远离轴。 切割部分可以被配置为从组织块切割样本，并且收集部分可以被配置为收集切割的样品并将切割的样品隔离在膜内。 槽可以被配置为当切割部分在缩回位置变得完全通电时使切割部分与要切割的组织的接触最小化。 致动器可以联接到集成组件，使得致动器的操作使得整合组件从缩回位置展开到可选择的扩展位置。
