An electrosurgical smoke evacuation pencil includes a handle housing, a suction conduit, an electrode, and a nozzle. The handle housing has a proximal end portion and a distal end portion and defines a lumen therethrough. The suction conduit is coupled to the handle housing and is configured to couple the electrosurgical pencil to a smoke evacuator. The electrode extends from the distal end portion of the handle housing and is configured to couple to a source of electrosurgical energy. The nozzle extends from the distal end portion of the handle housing and defines a lumen in fluid communication with the lumen of the handle housing. The nozzle is configured to transmit light from a light source through the nozzle and out of a distal end of the nozzle to form a light path illuminating therefrom.

Aspiration catheters for removing clot material from a patient, systems including these catheters, and methods of making and using these aspiration catheters may be configured to remove clot material in long, continuous strips that prevent the release of smaller clot fragments back into the vasculature. Also described herein are blood collection devices that may allow for safe and easy reperfusion of collected blood.

To provide robot-controlled surgical tools. [Solution] The device comprises an elongated shaft, a pull wire, a device base including a drive input assembly, and an adapter connectable to the device base, the adapter including an actuator, a coupler operably coupled to the actuator and connectable to the drive input assembly, the coupler having a gear assembly engageable with the actuator, and a tension mechanism configured to disengage the gear assembly from the actuator, wherein the actuator is operable to adjust the tension of the pull wire by operating the coupler while the gear assembly is engaged with the actuator, and the tension mechanism is operable to adjust the tension of the pull wire by operating the coupler while the gear assembly is disengaged from the actuator.
