Abstract

A system ( 502 ) includes an elongate ultrasound imaging probe ( 504 ) with a long axis and a top side that extends along the long axis. The elongate ultrasound imaging probe includes an elongate tubular handle ( 606; 1606 ), a head ( 1608 ), an elongate tubular shaft ( 608; 1610 ) between the elongate tubular handle and the head, and a transducer array ( 514 ) disposed in the head and configured to transmit in a sagittal plane, which is a plane that cuts through the long axis of the elongate tubular shaft, only in a direction extending out from the top side. The elongate tubular handle is both not centered on the elongate tubular shaft and not shifted down in the sagittal plane away from the top.

First claim

What is claimed is:

1. A system, comprising:
a needle biopsy guide, including:
a first portion configured to couple to an elongate ultrasound imaging probe;
a hollow channel configured to guide a needle or a cannula along a trajectory that is parallel to a long axis of the elongate ultrasound imaging probe and along a trajectory that is angled to the long axis;
a support configured to couple to a probe;
an access channel configured to support the needle or the cannula;
an actuator with a nub on one end; and
a pivot point;
wherein the actuator is pivotably mounted to the support at the pivot point and configured to move between a position in which the needle or the cannula traverses a trajectory parallel to the long axis of the elongate ultrasound imaging probe and a position in which the nub elastically deforms the needle or the cannula to traverse a trajectory angled to the long axis of the elongate ultrasound imaging probe.

2. The system of claim 1 , wherein the elongate ultrasound imaging probe further includes:
a top side that extends along the long axis:
an elongate tubular handle;
a head;
an elongate tubular shaft disposed between the elongate tubular handle and the head; and
a transducer array disposed in the head and configured to transmit in a sagittal plane only in a direction extending out from the top side;
wherein the elongate tubular handle is not centered on the elongate tubular shaft and is not shifted down in the sagittal plane away from the top.

3. The system of claim 1 , wherein the elongate ultrasound imaging probe further includes:
a first tracking device;
a needle biopsy instrument including a second tracking device;
a tracking system configured to track a spatial location of the needle biopsy instrument and the elongate ultrasound imaging probe based on signals from the first and second tracking devices;
an image processor configured to select a plane from volumetric image data generated with ultrasound echoes detected by a transducer array of the elongate ultrasound imaging probe based on the tracked spatial locations, wherein the plane includes an entry point of the needle biopsy instrument in an object and at least a trajectory of the needle biopsy instrument in the object; and
a display configured to display the selected plane.

4. A system, comprising:
a needle biopsy guide, including:
a first portion configured to couple to an elongate ultrasound imaging probe;
a hollow channel configured to guide a needle or a cannula along a trajectory that is parallel to a long axis of the elongate ultrasound imaging probe and along a trajectory that is angled to the long axis, wherein the hollow channel includes a common second portion and a third portion with different branching portions, wherein one of the branching portions is for the parallel trajectory and another of the branching portions is for the angled trajectory.

5. A system, comprising:
a needle biopsy guide, including:
a first portion configured to couple to an elongate ultrasound imaging probe;
a hollow channel configured to guide a needle or a cannula along a trajectory that is parallel to a long axis of the elongate ultrasound imaging probe and along a trajectory that is angled to the long axis, wherein the needle biopsy guide further comprising:
a first vertical leg, including:
an opening;
a second portion of a first bearing disposed in the opening; and
a third portion of the first bearing configured to move vertically within the second portion of the first bearing, wherein the third portion is configured to support the needle or the cannula;

a second vertical leg, including:
an opening;
a fourth portion of a second bearing disposed in the opening; and
a fifth portion of the second bearing configured to move vertically within the fourth portion of the second bearing, wherein the fifth portion is configured to support the needle or the cannula; and

a limiter,
wherein the limiter is configured to limit travel of the third portion of the first bearing of the first vertical leg, and the third portion of the first bearing of the first vertical leg and the fifth portion of the second bearing of the second vertical leg are configured to travel between a position providing the parallel trajectory and a position providing the angled trajectory.

6. A system, comprising:
a needle biopsy guide, including:
a first portion configured to couple to an elongate ultrasound imaging probe;
a hollow channel configured to guide a needle or a cannula along a trajectory that is parallel to a long axis of the elongate ultrasound imaging probe and along a trajectory that is angled to the long axis, wherein the hollow channel includes a plurality of hollow channels, and the needle biopsy guide further comprising:
a block, including:
a single column of the plurality of hollow channels,

wherein a hollow channel of the plurality of hollow channels provides a second portion configured to guide the needle or the cannula along the trajectory that is parallel to the long axis and a third portion configured to guide the needle or the cannula along the trajectory that is angled to the long axis.

7. The system of claim 6 , wherein the second portion and the third portion of the block partially overlap.

8. The system of claim 6 ,
wherein the single column of the plurality of hollow channels includes:
a single entry point at a first end of the second portion;
a single path extending through the second portion from the first end to a second opposing end of the second portion;
a first branch segment extending through the third portion from the second opposing end of the second portion and along a first branch path; and
a second branch segment extending through the third portion from the second opposing end of the second portion and along a second branch path.

9. The system of claim 8 , wherein the single path and the first branch segment provide parallel biopsy needle trajectories, and the single path and the second branch segment provide angled biopsy needle trajectories.

10. A system, comprising:
a needle biopsy guide, including:
a first portion configured to couple to an elongate ultrasound imaging probe;
a hollow channel configured to guide a needle or a cannula along a trajectory that is parallel to a long axis of the elongate ultrasound imaging probe and along a trajectory that is angled to the long axis, wherein the hollow channel includes an access channel, and the needle biopsy guide further comprising:
a support;
the access channel, wherein the access channel is configured to support the needle or the cannula; and
an actuator pivotably mounted to the support at a pivot point,
wherein the access channel is configured to provide a parallel trajectory in response to the actuator being in a non-actuating state, and
wherein the access channel is configured to provide an angled trajectory in response to the actuator being in an actuating state.

11. The system of claim 10 , the actuator including:
a shaft, including:
a first end; and
a second end; and

a nub disposed proximal to the second end.

12. The system of claim 11 , wherein in the non-actuating state the nub is configured to reside below the access channel and the access channel provides a parallel trajectory.

13. The system of claim 12 , wherein in the actuating state the nub physically contacts a portion of the access channel and urges the portion away from the support, which bends or deforms the access channel, providing an angled trajectory.

14. The system of claim 12 , wherein in the actuating state the actuator is configured to pivo
