Abstract: A device for moving contents of a tube by acting on the exterior of the tube is provided. The device includes a housing having a tube passageway extending along a length thereof for holding a tube therein. A first roller and a second roller are moveable between a first position and a second position and configured to compress the tube in the second position. A first roller chassis is coupled to the housing for mounting the first roller therein and a second roller chassis is coupled to the housing for mounting the second roller therein. The first and second roller chassis are moveable between a first position in which the tube is disengaged and a second position in which the tube is engaged. A lever operably coupled to the housing causes the first or second roller to pivot and engage the tube positioned within the passageway.

Abstract: A tissue marking system for marking a tissue sample includes at least one container and at least one ink stored in the container. The at least one ink may include a plurality of inks each of a different colored and may be sterile or non-sterile. The ink has a viscosity of from 85 ku to 115 ku such that when applied to a tissue surface having adjacent tissue margins, the ink does not migrate onto an adjacent tissue surface.

Abstract: An ink composition for marking a tissue specimen is provided. The ink composition has a general formula of 30.0 wt. % to 54.0 wt. % of an alkali soluble styrene; 0.3 wt. % to 1.7 wt. % ethyl hydroxyethyl cellulose; 8.0 wt. % to 35.0 wt. % colorant; 0.0 wt. % to 13.0 wt. % pigment; 23.0 wt. % to 47.0 wt. % deionized water; 0.35 wt. % to 1.65% defoamer and 0.1 wt. % to 1.1 wt. % preservative. The inks in accordance with the invention may have a peak transmission in the visible spectrum at a wavelength of from 322 nm to 716 nm or having a lineal UV-Vis spectrum with no visible peak transmission between 250 nm and 950 nm. When applied to a tissue specimen the ink compositions do not bleed onto adjacent tissue margins. When view under a microscope the color of the ink compositions can be distinguished from each other.

Abstract: A device for moving contents of a tube by acting on the exterior of the tube is provided. The device includes a housing having a top portion and a bottom portion, the top portion including a tube passageway extending along a length thereof for holding a tube therein. A roller housed within a roller chassis contacts the tube and is configured to move between a first position in which the tube is disengaged and a second position in which the tube is engaged. A second roller is rotatably coupled to an actuator for rotatably energizing the second roller and is moveable between a first position in which the tube is disengaged and a second position in which the tube is engaged. A lever is operably coupled to the housing and configured to actuate a motor to move the second roller to the second position. The first roller and the second roller are configured to compress the tube to move contents within the tube.

Abstract: A single-use tissue marking system for use in marking a tissue sample includes a container and a first number of ink reservoirs at least partially defined by the container. Each reservoir contains ink of a different color. The system also includes a second number of applicators. Each applicator is configured to absorb a quantity of ink for application to the tissue sample. A cover is coupled to and cooperates with the container to fully enclose each of the first number of ink reservoirs.

Abstract: A tissue marking system is configured to mark a tissue sample. The tissue marking system includes an actuator portion movable between an actuated position and a non-actuated position and a jaw portion coupled to the actuator portion and movable between an open position and a closed position in response to movement of the actuator portion from the actuated position to the non-actuated position. The jaw portion includes a first tooth and a second tooth configured to engage the tissue sample when the jaw portion moves from the open position to the closed position.

Abstract: A surgical instrument for use with a trocar that provides access to an interior portion of a patient. The instrument includes an elongated rod portion sized to fit within the trocar and a leg portion attached to the elongated rod portion and movable with respect to the leg portion to define an acute angle therebetween. A marker is attached to the leg portion and is operable to apply a marking substance to the interior of the patient.
