摘要： A biopsy needle assembly for use in a biopsy gun includes coaxially slidably engaged outer needle and inner needles. The inner needle defines a cavity adjacent its distal end for receiving a tissue sample. A first hub is attached to the proximal end of the inner needle, and a second hub is attached to the proximal end of the outer needle. An elongated pin having a first end and a second end is fixedly attached to the first hub at the first end of the pin. The second end is in sliding contact with the second hub so that the second hub and the pin are slidable relative to each other. A stop engagement is provided between the second end of the pin and the second hub and is configured to prevent disengagement of the outer and inner needles and to maintain a specific physical relationship between the hubs.
摘要翻译：用于活检枪的活检针组件包括同轴可滑动地接合的外针和内针。内针限定邻近其远端的腔以接收组织样本。第一轮毂附接到内针的近端，并且第二轮毂连接到外针的近端。具有第一端和第二端的细长销在销的第一端处固定地附接到第一毂。第二端部与第二轮毂滑动接触，使得第二轮毂和销可相对于彼此滑动。在销的第二端和第二轮毂之间提供止动接合，并且构造成防止外针和内针的分离并且保持轮毂之间的特定物理关系。
