Abstract
A biopsy device includes a drive unit configured to receive a disposable unit having a needle carrier. The drive unit is configured to move a cutting element such that the needle carrier is driven a predetermined distance to move a needle-shooting mechanism to a cocked configuration. A user-actuatable control is configured to release the needle-shooting mechanism to cause the needle-shooting mechanism to shoot a biopsy needle simultaneously with the cutting element by an amount of the predetermined distance.

45. A biopsy device, comprising:
-
a disposable unit including; a needle carrier configured to move in a first direction and a second direction opposite to the first direction; and a biopsy needle having a cutting element with both the biopsy needle and the cutting element coupled to the needle carrier, and a sample chamber in the biopsy needle, the cutting element having a cutting blade, the cutting element being configured to move the cutting blade relative to the sample chamber; and a drive unit configured to receive the disposable unit, the drive unit having a needle-shooting mechanism with a cocked configuration and a released configuration, the needle-shooting mechanism having a spring and a clamping carriage, the clamping carriage being configured to drivably engage the needle carrier; the drive unit configured to move the cutting element to drive the needle carrier in the second direction by a predetermined distance to move the needle-shooting mechanism to the cocked configuration; and the drive unit having a user-actuatable control configured to release the needle-shooting mechanism to cause the needle-shooting mechanism to shoot the needle carrier including the biopsy needle simultaneously with the cutting element in the first direction by an amount of the predetermined distance. - View Dependent Claims (46, 47, 48, 49, 50)

51. A biopsy device, comprising:
-
a biopsy needle including a sample chamber and a cutting element having a cutting blade; a drive unit having a needle-shooting mechanism configured to be switched from a cocked configuration to a released configuration, the drive unit being configured to cause relative movement of the cutting element and the biopsy needle by a predetermined distance to cock the needle-shooting mechanism, and the needle-shooting mechanism being configured to shoot the biopsy needle simultaneously with the cutting element in a distal direction by an amount of the predetermined distance when switched from the cocked configuration to the released configuration. - View Dependent Claims (52, 53, 54, 55)

56. A method of operating a biopsy device, comprising:
-
selecting a shooting distance of a biopsy needle and a cutting sheath; moving the biopsy needle in a proximal direction by an amount of the shooting distance to cock a cocking apparatus; releasing the cocking apparatus to shoot the biopsy needle simultaneously with the cutting sheath in a distal direction by an amount of the shooting distance; and operating the cutting sheath to collect a tissue sample. - View Dependent Claims (57, 58)
