Autonomous waste collection assembly and medical waste collection system and methods

A method of operating a waste collection unit including a light assembly separate from a display panel. A vacuum level of the vacuum drawn on a waste canister is measured with a vacuum sensor.

A commanded vacuum level may be received on the display panel, and a colored image indicative of a commanded vacuum level may be displayed on the display panel. The waste collection unit may include plural manifold receivers each configured to receive a manifold. The light assembly that is adjacent the manifold receiver corresponding to the waste canister into which the vacuum is being drawn may be operated to selectively emit light to emit light at different colors or different patterns based on the operating state of the waste collection unit.

A system is provided comprising a robotic instrument for use with a tool. In some versions, the robotic instrument comprises a hand-held portion to be held by a user and a tool support movably coupled to the hand-held portion to support the tool. A plurality of actuators operatively interconnect the tool support and the hand-held portion to move the tool support in three degrees of freedom relative to the hand-held portion. An optional constraint assembly may operatively interconnect the tool support and the hand-held portion to constrain movement of the tool support relative to the hand-held portion in three degrees of freedom. A guidance array assists users in positioning the tool and/or portions of the instrument.

A manifold for a medical/surgical waste collection system. An outlet opening and a fitting are in fluid communication with a manifold volume within a housing. The fitting receives a suction line. A filter element with porous features is disposed within the housing such that a fluid communication path is established across the filter element. The porous features trap material entrained within the fluid. A material collection volume is at least partially distal to and below a bottom of the filter element. As the fluid and the material is drawn through the fluid communication path, the material collects within the material collection volume. A flow diverter may be positioned within the housing for directing the material towards the material collection volume. The material collection volume may be at least partially defined by a tissue trap removably coupled to the housing.
