Abstract
A biopsy assembly for collecting tissue samples by means of a biopsy needle when introduced in a body cavity. The biopsy assembly comprises an elongated member (101), with a longitudinal axis (102), configured with: a first needle guide (203) arranged to guide a needle in a direction transverse to the longitudinal axis (102), and a second needle guide (204, 303) arranged to guide a needle in a direction along the elongated member (101).
Claims15
A biopsy assembly for collecting tissue samples with a biopsy needle when introduced in a body cavity, comprising:
- an elongated member, with a longitudinal axis;
- a first needle guide structure with an axis extending in a first direction transverse to the longitudinal axis;
- a second needle guide structure that is separate from said first needle guide, wherein the second needle guide structure includes an axis extending in a second direction along the longitudinal axis of the elongated member;
- a protrusion extending from a first end of the elongated member in a direction along the longitudinal axis of the elongated member;
- and
- a semi-circular fixation collar disposed at a second end of the elongated member, wherein the first and second ends are opposing ends along the longitudinal axis,
- wherein the elongated member is a semi-cylindrical member with a half-circle side and a planar side and the semi-circular fixation collar is disposed at an outer perimeter of the half-circle side, wherein the first needle guide structure extends from the half-circle side through the semi-cylindrical member to the planar side and the second needle guide structure is disposed outside of a perimeter of the half-circle side.
An ultrasound probe for cavity scanning of a body and for guiding a biopsy needle, said ultrasound probe comprising:
- an elongated body, including:
- a first end region at a first end of the elongated body;
- an ultrasound transducer providing an imaging plane, wherein the ultrasound transducer is disposed at the first end region;
- a second end region at a second end of the shaft, wherein the first and second end regions are at opposing end of the elongated body;
- an intermediate region disposed between the first end region and the second end region, wherein the intermediate region is recessed in the elongated body relative to the first and second end regions such that the elongated body includes a recess;
- and
- an indentation in a wall of the first end region, wherein the wall is transverse to the elongated body, and the indentation extends from the recess into the first end region;
- and
- a needle guide, including:
- a semi-cylindrical member with a half-circle side and a planar side;
- a first needle guide structure which guides an elongated needle in only a first direction transverse to a longitudinal axis of the probe wherein the first needle guide structure extends from the half-circle side through the semi-cylindrical member to the planar side,
- a second needle guide structure which guides an elongated needle in only a second direction longitudinal to the probe, wherein the second needle guide structure is disposed outside of a perimeter of the half-circle side;
- and
- a protrusion disposed on a cross-sectional side of the semi-cylindrical member, wherein the protrusion is disposed between the first needle guide structure and the second needle structure,
- wherein the indentation engages the protrusion, securing the needle guide to the elongated body.
