Tissue removal device and method of use

摘要

A biopsy device for acquiring a tissue sample is disclosed. The biopsy device comprises a partoff mechanism which can have at least a tab and an actuator. The actuator can be used to control the angle of the tab and thus partoff a tissue sample. The tab may be on a cutter tube, which may have a sharp distal end which may core the samples from the mass of tissue. Multiple tissue samples may be collected.

主权项

1. A tool for acquiring a tissue comprising:
a cutter tube with an open distal end and a partoff tab; an outer tube located concentrically outside the cutter tube with an open distal end; and a handle; wherein the partoff tab has a partoff tab first end and a partoff tab second end, wherein the partoff tab first end is secured to the cutter tube, and wherein the partoff tab second end is secured to the outer tube, wherein the cutter tube has a tubular longitudinal axis, and wherein the partoff tab has a longitudinally expanded configuration and a longitudinally contracted configuration, and wherein the cutter tube and the outer tube are configured to rotate with respect to the handle when the partoff tab is in the longitudinally contracted configuration; wherein the length of the partoff tab along the tubular longitudinal axis in the longitudinally expanded configuration is longer than the length of partoff tab along the tubular longitudinal axis in the longitudinally contracted configuration; and wherein the cutter tube and the outer tube are configured to simultaneously rotate at the same velocity at the partoff tab first end and the partoff tab second end.
