Abstract
A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The motor can oscillate back and forth to cause the needle to oscillate. Structures are described to permit one-handed operation of the device and automatic motor activation based on attaining a desired plunger position. Non-electric motors are described along with a mechanism for axial oscillation of the needle.
Claims9
A device, comprising:
- a needle;
- a syringe coupled to the needle, wherein the syringe comprises a barrel and a plunger slidably disposed in the barrel;
- an electric motor coupled to the needle to rotate the needle;
- a gear assembly coupling the needle to the electric motor to cause reciprocal axial translation of the needle;
- and
- a movable activation mechanism configured to permit one handed operation or a single one finger motion which starts the motor and moves the plunger relative to the barrel thereby pulling a vacuum in the needle.

A device, comprising:
- a needle;
- a syringe coupled to the needle, wherein the syringe comprises a barrel and a plunger slidably disposed in the barrel;
- a non-electric tension assembly coupled to the needle to rotate the needle back and forth and axially translate the needle in a reciprocal manner;
- and
- a movable activation mechanism configured to permit one handed operation or a single one finger motion which controls the non-electric tension assembly to rotate the needle back and forth and axially translate the needle in a reciprocal manner and pulls a vacuum in the needle.
