The present invention provides an improved hoop-type amusement device adapted with a counter for counting the number of revolutions achieved by the user. A power source is contained within the housing and the removable unit includes a biopsy needle module and a pressure source that can be integrated into the housing such that the biopsy device is fully operational without the need for wires or cables extending from the housing to connect to external units. Radially outward peripheral edges include a cutting insert mounting structure that projects axially below a bottom side of the body.
