Zusammenfassung:A biopsy device includes a body, a needle, a cutter, a motor, a power source, a vacuum source, and a cutter translation assembly. The needle extends distally from the body and receives tissue. The cutter translates with respect to the needle to sever tissue received by the needle. The motor is disposed within the body and rotates a drive shaft in a first direction. The power source is disposed within the body and powers the motor. The vacuum source is disposed within the body and provides vacuum in at least one of the needle and the cutter. The cutter translation assembly is disposed within the body and translates the cutter proximally and distally with respect to the needle in response to rotation of the drive shaft in the first direction.
