Abstract

A biopsy system includes a handle for receiving a removable biopsy device which includes an inner needle having a distal tip configured for piercing tissue, a tissue sensing unit for characterizing tissue properties, a recess formed longitudinally in the inner needle proximal to the distal tip for receiving a tissue portion from a region of interest, an outer sheath configured to move relatively to the inner needle, and a connector element for receiving sensing signals from the tissue sensing unit. The handle includes a socket tiltable between a rest position and a tilted position, and having a sliding channel, and a connection board. The connector element includes a coupling matrix while the connection board has a receiving matrix. Fixation pins in one matrix cooperate with holes in a second matrix to facilitate alignment of the connector element with the connection board.

Dependent claims

A biopsy system comprising:

(a) a removable biopsy device comprising:
an inner needle comprising a tip configured to pierce tissue and a tissue sensing unit for characterizing tissue properties, at least part of said tissue sensing unit being positioned on said inner needle,
a recess formed longitudinally in said inner needle proximal to said tip and configured for receiving a tissue portion from a region of interest;
and
an outer sheath configured to change position relative to said inner needle between a forward position of said sheath in which said sheath covers the recess and a backward position of the sheath in which said recess and said at least part of said tissue sensing unit are uncovered, said outer sheath comprising a cutting edge at its distal end configured to cut and enclose said tissue portion into said recess when moving relatively to the needle from the backward position to the forward position;
a connector element configured for receiving sensing signals from said tissue sensing unit;
and
(b) a handle for receiving said removable biopsy device;
said handle comprising a registration assembly including:
a socket tiltable between a rest position and a tilted position, and having a sliding channel for receiving said connector element;
and
a connection board for electrically coupling said connector element when the connector element is received in the sliding channel and the socket is in the rest position.
