a scope device including an elongated shaft extending from a scope device distal end, the elongated shaft having a working channel extending therethrough and being configured to be inserted through the lumen of the sheath; a vibration motor coupled to the elongated shaft and configured to transmit vibration energy along a length of the elongated shaft to dislodge debris within the target surgical site, wherein the vibration motor is coupled to the elongated shaft via a vibration collar, the vibration collar extending from a vibration collar proximal end to a vibration collar distal end and including a housing configured to house the vibration motor; a vacuum pump connected to the elongated shaft to suction dislodged debris from the target surgical site through the elongated shaft; and a processor configured to receive fluid flow data from a flow meter at a distal end of the elongated shaft, the flow meter configured to measure a fluid flow rate in the working channel. ### Claim 2 (depends on 1) The system of claim 1, wherein the processor is configured to automatically turn the vibration motor on when the flow meter detects that the fluid flow rate is less than a desired fluid flow rate. ### Claim 3 (depends on 1) The system of claim 1, wherein the elongated shaft includes at least one sensor, the at least one sensor transmitting sensor data relating to the target surgical site to the processor and wherein if the at least one sensor detects an obstruction in the target surgical site, the processor automatically turns the vibration motor on. ### Claim 4 (depends on 1) The system of claim 1, wherein the vibration collar includes a channel extending from the vibration collar proximal end to the vibration collar distal end and sized and shaped to receive the elongated shaft therethrough. ### Claim 5 (depends on 1) The system of claim 1, wherein the vibration motor includes a rotatable shaft and at least one eccentric weight coupled thereto. ### Claim 6 (depends on 1) The system of claim 1, further comprising a collection canister, the collection canister being fluidly connected to both the scope device and the vacuum pump so that dislodged debris is drawn from the target surgical site to the collection canister. ### Claim 7 (depends on 1) The system of claim 1, wherein the sheath includes a seal configured to prevent back flow of fluid through the lumen. ### Claim 8 (depends on 1) The system of claim 1, wherein the scope device further comprises a handle, the handle including at least one button configured to manually control the vibration motor or a power of the vibration motor.
