Abstract

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 holder rotation mechanism is operable to rotate the manifold to successively align each of the chambers with the cutter lumen. A controller in communication with the rotation mechanism is configured to rotate the manifold to a presentation position to present a collected tissue sample within a chamber to a user (e.g., at an angular position approximately 90 degrees from the cutter lumen). The controller is further configured to rotate the manifold align the next, empty chamber with the cutter lumen in response to a user input instructing the biopsy device to obtain another tissue sample.

Claims

1. A method of operating a rotatable tissue sample holder of a biopsy device, wherein the tissue sample holder has a plurality of discrete tissue sample compartments, wherein the biopsy device has a cutter defining a cutter lumen, wherein the method comprises:

(a) capturing a first tissue sample with the cutter;

(b) communicating the first tissue sample to a first tissue sample compartment of the tissue sample holder, wherein the first tissue sample compartment receives the first tissue sample when the first tissue sample compartment is at a first rotational position;

(c) rotating the tissue sample holder to position the first tissue sample compartment at a second rotational position to present the first tissue sample to a user; and

(d) rotating the tissue sample holder to position a second tissue sample compartment of the tissue sample holder at the first rotational position to acquire a second tissue sample in the second tissue sample compartment, wherein the second tissue sample compartment is adjacent to the first tissue sample compartment, wherein the first tissue sample compartment is at a third rotational position when the second tissue sample compartment is at the first rotational position.

2. The method of claim 1, wherein the act of rotating the tissue sample holder to position the first tissue sample compartment at a second rotational position comprises rotating the tissue sample holder in a first direction;

wherein the act of rotating the tissue sample holder to position a second tissue sample compartment of the tissue sample holder at the first tissue rotational position comprises rotating the tissue sample holder in a second direction, opposite to the first direction.

4. The method of claim 1, wherein the first rotational position is between the second rotational position and the third rotational position.

5. The method of claim 1, further comprising:

(a) receiving a user input, wherein the user input comprises instructions to initiate either a clear probe cycle or an aspirate cycle; and

(b) returning the first tissue sample compartment to the first rotational position before performing the act of rotating the tissue sample holder to position the second tissue sample compartment of the tissue sample holder at the first rotational position, wherein the act of returning the first tissue sample compartment to the first rotational position is performed in response to the received user input.

6. The method of claim 1, wherein the first rotational position is located approximately at a 12 o'"'"'clock position.

7. The method of claim 5, wherein the second rotational position is located at either approximately a 3 o'"'"'clock position or approximately a 9 o'"'"'clock position.

8. The method of claim 6, further comprising receiving an input selecting whether to use the 3 o'"'"'clock position or the 9 o'"'"'clock position as the second rotational position, wherein the second rotational position is designated in accordance with the received input.

9. The method of claim 8, wherein the biopsy device comprises a housing having a left side and a right side, wherein the left side and the right side each have a respective user interface feature operable to accept instructions from the user relating to operation of the biopsy device, wherein the received input selecting whether to use the 3 o'"'"'clock position or the 9 o'"'"'clock position as the second rotational position is based at least in part on which of the user interface features receives instructions from the user.

3. A method of operating a rotatable tissue sample holder of a biopsy device, wherein the tissue sample holder has a plurality of discrete tissue sample compartments, wherein the biopsy device has a cutter defining a cutter lumen, wherein the method comprises:

(a) indexing a first tissue sample compartment relative to the cutter lumen to receive a first tissue sample;

(b) communicating the first tissue sample through the cutter lumen to the indexed first tissue sample compartment;

(c) rotating the tissue sample holder a first time to present the first tissue sample to a user, wherein the act of rotating the tissue sample holder the first time rotates the first tissue sample compartment from an indexed position to a presentation position; and

(d) indexing a second tissue sample compartment relative to the cutter lumen to receive a second tissue sample, wherein the act of indexing the second tissue sample compartment comprises rotating the tissue sample holder a second time, wherein act of rotating the tissue sample holder the second time rotates the first tissue sample compartment away from the presentation position, wherein the second tissue sample compartment is adjacent to the first tissue sample compartment.

10. A method of operating a rotatable tissue sample holder of a biopsy device, wherein the tissue sample holder has a plurality of discrete tissue sample compartments, wherein the biopsy device has a cutter defining a cutter lumen, wherein the method comprises:

(a) indexing a first tissue sample compartment relative to the cutter lumen to receive a first tissue sample;

(b) communicating the first tissue sample through the cutter lumen to the indexed first tissue sample compartment;

(c) rotating the tissue sample holder a first time to present the first tissue sample to a user, wherein the act of rotating the tissue sample holder the first time rotates the first tissue sample compartment from an indexed position to a presentation position;

(d) rotating the tissue sample holder a second time to locate a second tissue sample compartment at the indexed position to receive a second tissue sample, wherein act of rotating the tissue sample holder the second time rotates the first tissue sample compartment away from the presentation position;

(e) rotating the tissue sample holder a third time to present the second tissue sample to the user, wherein the act of rotating the tissue sample holder the third time rotates the second tissue sample compartment from the indexed position to the presentation position; and

(f) rotating the tissue sample holder a fourth time to locate a third tissue sample compartment at the indexed position to receive a third tissue sample, wherein act of rotating the tissue sample holder the fourth time rotates the second tissue sample compartment away from the presentation position.
