Cutting head for tissue collection device

An instrument for collecting tissue from a body cavity, the collection instrument comprising:

• a hollow tubular body that defines a longitudinal axis, the tubular body comprising a proximal end portion that terminates at a proximal-most end, a distal end portion that terminates at a distal-most end, and a middle section extending between the proximal end portion and the distal end portion, the middle section having a first end contiguous with and next to the proximal end portion, and a second end contiguous with and next to the distal end portion, the tubular body comprising a tubular wall extending between the proximal-most end and the distal-most end, the tubular wall defining an outer wall surface and an inner wall surface, the tubular wall surrounding a passage that extends to the distal end portion of the tubular body,
• wherein:
• the distal end portion comprises a core drill with a cutting tip, the cutting tip defining a first aperture, a second aperture opposite the first aperture, and a web extending between the first aperture and the second aperture, the web tapering to a drill point at the distal-most end of the tubular body, the first aperture and the second aperture each comprise an outline bounded by a linear first edge, a linear second edge, a linear third edge, and a curved fourth edge,
• the linear first edge and the linear second edge lie in a first plane extending along the longitudinal axis, and
• the linear third edge and the curved fourth edge lie in a second plane transverse to the longitudinal axis and transverse to the first plane.
