| A vacuum cleaning head includes a pressure chamber having a first chamber section and a second chamber section which is moveable relative to the first chamber section in response to a pressure differential thereacross from a first position to a second position, and a control mechanism located within the pressure chamber. The control mechanism has a first state for inhibiting the movement of the second chamber section in response to said pressure differential beyond a third position intermediate the first and second positions, and a second state for allowing the second chamber section to move in response to said pressure differential to the second position. The control mechanism is arranged to change between the first and second states in response to a movement of the second chamber section from the third position. This can allow the pressure chamber to toggle between different configurations through varying the pressure differential across the second chamber section, for example to raise or lower part of the cleaner head, or to selectively activate or deactivate an agitator. | ||||||

| The present invention is a tool for use during surgical procedures for cleaning tissue and debris from the in-vivo end of surgical instruments. The tool is used during various surgical procedures to clean debris from various surgical instruments. A substantially cylindrical, hollow shaft extends from one or both ends of the invention. An elastomeric suction tip coupler is configured at one or both ends of the hollow shaft to allow connection of commonly used suction tips. The invention includes a plurality of substantially parallel, elastomerized, concentric cleaning blades. The user of the invention may insert or swipe an instrument to be cleaned along cleaning blade edges configured at the peripheries of the cleaning blades, thereby causing the instrument to be cleaned.
