An autonomous medical waste collection assembly. A base supports a waste canister in fluid communication with a manifold receiver, and a suction pump. A controller is in electronic communication with a powered wheel and configured to transmit a movement signal for a motor to power the powered wheel to move the assembly along a floor surface. The assembly may be operable in an autonomous mode in which the powered wheel automatically moves the assembly along the floor surface, and a manual mode in which resistance from the powered wheel is negated to provide for manual movement of the assembly. The controller may be further configured to steer the assembly based on a current location input signal, and a disposal location input signal from a locator network within the medical facility that is indicative of a location of a disposal station.

Autonomous waste collection assembly and medical waste collection system and methods

A method of method of manufacturing a surgical waste collection manifold with a volume collected datum and a rover type to ensure compatibility with a surgical waste collection rover is provided. The surgical waste collection rover including a vacuum pump and a receiver defining an opening. The method includes obtaining a second manifold. The second manifold having a second housing defining a surface, the housing defining a second manifold volume and a second outlet opening in fluid communication with the second manifold volume. The method may further include coupling a second circuit to the surface of the second manifold, the second circuit comprising a second memory device including a third memory bank and a fourth memory bank, the third memory bank including a fifth memory field and the fourth memory bank including a sixth memory field. The method may further include programming the fifth memory field with an encrypted first hash digest based on the rover type and programming the sixth memory field with an encrypted second hash digest based on the volume collected datum.

Manifold for filtering medical waste being drawn under vacuum into a medical waste collection system and related methods

An autonomous medical waste collection assembly comprises a base adapted to be positioned near a patient. At least one wheel is powered to move the base along a floor surface. A waste collection unit is coupled to the base for receiving medical waste from the patient. The waste collection unit includes a canister for holding the medical waste. A controller is operable to initiate a waste disposal protocol. The waste disposal protocol includes transmitting a movement signal to the powered wheel for automatically moving the autonomous medical waste collection assembly away from the patient to a disposal station. A user input device is in communication with the controller. The user input device is adapted to provide a user input signal in response to being actuated by a user. The controller is configured to initiate the waste disposal protocol in response to receiving the user input signal.

Manifold for filtering medical waste being drawn under vacuum into a medical waste collection system

An electrosurgical system preferably used for denervation procedures of nerve tissue has a control unit and a pluggable electrode assembly. The electrode assembly has a disposable cannula and a preservable supply electrode assembly. The cannula has a tubular body that projects axially from a pointed distal end for piercing tissue to a proximal end engaged to a first coupling assembly of the cannula. The supply electrode assembly has a second coupling assembly and a supply electrode that projects axially and removably into a through-bore of the body when in an operating state. The first and second coupling assemblies are configured to releasably interlock to prevent clockwise and counterclockwise rotation of the supply electrode in the body.

Electrode assembly with separate bipolar cannula and supply electrode

An electrosurgical system preferably used for denervation procedures of nerve tissue has a control unit and a pluggable electrode assembly. The electrode assembly has a preferably disposable cannula and a preservable supply electrode assembly. The cannula has a tubular body that projects axially from a preferably pointed distal end for piercing tissue to a proximal end engaged to a first coupling assembly of the cannula. The body carries a first contact exposed directly to the nerve tissue and connected electrically to a terminal of the first coupling assembly. The supply electrode assembly has a second coupling assembly and a supply electrode that projects axially and removably into a through-bore of the body when the tool is in an operating state. The second coupling assembly carries a terminal that abuts the first coupling assembly when the coupling assemblies are mated. Preferably the supply electrode carries a temperature sensor for temperature measurement of the targeted tissue and processing by the control unit. Preferably, the electrode assembly also includes a stylet having a rod that fits into the through-bore of the body when the supply electrode assembly is removed and the tool is in a tissue penetrating state.
