An improved biopsy specimen cutter utilizes a wire loop, attached to a hand-manipulable trigger mechanism, for severing the tissue sample from the host. A removable dilator is insertable into the biopsy specimen cutter for the purpose of positioning the cutter adjacent the tissue to be removed, ...
摘要：An improved biopsy specimen cutter utilizes a wire loop, attached to a hand-manipulable trigger mechanism, for severing the tissue sample from the host. A removable dilator is insertable into the biopsy specimen cutter for the purpose of positioning the cutter adjacent the tissue to be ...
The fundamental goal is the minimization of the insertion force at the biopsy punch tip and the soft tissue during insertion procedures. As predicted by a 3D finite element simulation, a reduction of 20-40% in the insertion force has been achieved, and encourages further studies and their ...
The cutter assembly includes a hollow cutter, and the hollow cutter can be removed from the probe assembly without disassembling the probe assembly. The method can include the steps of positioning the tissue receiving port in the tissue to be sampled; removing the cutter from the biopsy device;...
BIOPSY DEVICE WITH SELF-REVERSING CUTTER DRIVE A biopsy device includes a body, a needle, a cutter, and a cutter drive mechanism. The needle extends distally from the body. The cutter is movable relative to the needle to sever a tissue sample. The cutter drive mechanism is driven by ......
This needle has a pointed terminal to be stabbed into the tissue and a bowl for accepting the tissue group. The bowl further has a cutter for cutting the tissue group accepted in the bowl and at least one tissue marker element for putting the mark onto the surface of the tissue. The ...
A biopsy system includes a biopsy device having a translating cutter for severing tissue samples and a vacuum control module. The vacuum control module is separate from the biopsy device. The vacuum control module includes a vacuum pump and vacuum canister, and is portable by a single hand. The...
All samples, both nanobiopsies and single-cells, were taken from tissue obtained from a single healthy control (n = 1). Samples were successfully enriched using targeted PCR and then sequenced. Nanobiopsy lysate underwent NGS (MiSeq, Illumina) with an average sequencing depth of > 10...
The present invention relates to a revolving tissue sample holder for a biopsy device. The biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one embodiment, the tissue sample holder has a rotatable manifold that is configured to ...
A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder includes a rotatable manifold, and has a plurality of chambers that are each configured to separately hold tissue samples. A tissue sample...
