Embodiment Construction
[0129] attached figure 1 A simplified schematic illustration of a biopsy device having features of the invention is shown. The device includes a biopsy needle 108 comprising a hollow needle 50 in which a longitudinally movable tissue sample containment device 52 is disposed. The sample containment device includes a tapered distal tip 54 and a cavity or canoe 56 for containing a tissue sample. The sample containment device includes a vacuum port 58 that is in fluid communication with the canoe 56 to allow tissue to be drawn into the canoe once it is placed within the organism at the location to be examined. Vacuum is provided by a vacuum pump (not shown). The distal portion of the hollow needle 50 provides a circumferential cutting edge 60 for severing a tissue sample drawn into the canoe 56 . The device includes a spring-loaded firing mechanism that is attached to the figure 1 Illustrated schematically with coil spring 62 , the firing mechanism is configured to move hollow...

The present invention provides a biopsy device for harvesting at least one tissue sample from a suspect tissue mass in a body of a living being. The device comprises a hollow needle having a distal end for inserting into a living being; a cutting mechanism for cutting at leas tone tissue sample; a sample accommodating device with cavity which can be accommodated in the hollow needle; and a transport device for moving the sample accommodating device between a first extending position and a second retract position in the hollow needle, wherein the sample accommodating device with cavity is at distal position at the first extending position, and is at a near position when at the second retract position, and the transport device also comprises a bending long element. The sample accommodating device can move along motion axis in the hollow needle, and at least one of the hollow needle and the sample accommodating device is configured to direct the sample accommodating device relative to the hollow needle basically in a plane vertical to the motion axis.
Description
[0001] This application is a divisional application of the invention patent application with the application number 2005800294305, the application date being July 08, 2005, and the invention title being "transport system for biopsy device". technical field [0002] The present invention relates to biopsy devices for harvesting tissue samples of the human or animal body. The present invention relates particularly, but not exclusively, to percutaneous biopsies, where it is desired to access the mass of tissue to be examined in a minimally invasive manner. In particular, the present invention relates to the delivery of a sample-containing device containing one or more harvested tissue samples into an outer hollow needle of a biopsy device. Background technique [0003] For diagnostic purposes, it may be desirable to obtain a tissue sample of a human or animal body for in vitro cytological and / or histological examination. Tissue sampling can be performed with open or percutaneo...
