摘要： An embodiment of the invention includes a device for collecting body tissue. The device includes an inner end effector comprising a hollow portion, a distal edge that defines an opening of the hollow portion at least a portion of which is sufficiently sharpened to cut body tissue, and a proximal end configured to receive an inner tubular member. The device also includes an outer end effector comprising a flexible extension on a distal end with an edge at least a portion of which is sufficiently sharpened to cut body tissue and biased inwardly toward the hollow portion of the inner end effector to cover the opening, and a proximal end configured to receive an outer tubular member. The inner end effector is slidably disposed within the outer end effector.

摘要： An instrument for collecting body tissue includes a tubular cutting member having an exterior surface, a proximal end, and a distal end capable of penetrating body tissue; and a flexible cutting extension coaxially and slidably disposed around the exterior surface of the cutting member, the flexible cutting extensions having a proximal end and distal end capable of cutting tissue located at the distal end of the cutting member and covering the distal end of the cutting member so that tissue that has entered the cutting member is retained in the cutting member. A first tubular member may be connected to the cutting member, and a second tubular member mayb connected to the cutting extension, the second tubular member being coaxially disposed on the first tubular member. A handle mechanism may be connected to the first and second tubular members, the handle mechanism allowing relative movement between the first and second tubular members such that the flexible cutting extension may be extended beyond the distal end of the cutting member.
摘要翻译：用于收集身体组织的仪器包括具有外表面，近端和能够穿透身体组织的远端的管状切割构件; 以及柔性切割延伸部，其同轴且可滑动地设置在所述切割构件的外表面周围，所述柔性切割延伸部具有近端和远端，所述近端和远端能够切割位于所述切割构件的远端处的组织并覆盖所述切割的远端使得已经进入切割构件的纸巾被保留在切割构件中。第一管状构件可以连接到切割构件，并且第二管状构件可以连接到切割延伸部，第二管状构件同轴地设置在第一管状构件上。手柄机构可以连接到第一和第二管状构件，手柄机构允许第一和第二管状构件之间的相对运动，使得柔性切割延伸部可以延伸超过切割构件的远端。
