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.

Oscillating syringe system and needle

A telescoping assembly such as an endobronchial ultrasound needle (EBUS) assembly includes a motor coupled to a biopsy needle within a telescoping housing to rotate (such as to oscillate) the needle during tissue harvest to improve harvesting.
