Abstract: A robotic system and methods for performing spine surgery are disclosed. The system comprises a robotic manipulator with a tool to hold a screw and to rotate the screw about a rotational axis. The screw is self-tapping and has a known thread geometry that is stored by one or more controllers. A navigation system tracks a position of a target anatomy. Movement of the robotic manipulator is controlled to maintain the rotational axis of the surgical tool along a planned trajectory with respect to the target anatomy based on the tracked position of the target anatomy. In autonomous or manual modes of operation, the rotational rate of the screw about the rotational axis and/or an advancement rate of the screw linearly along the planned trajectory is controlled to be proportional to the known thread geometry stored in the memory.

Abstract: Disclosed herein are techniques including a robotic manipulator including a surgical tool to interface with and rotate the screw about a rotational axis. A haptic device includes an actuator and a rotational interface coupled to the actuator and the rotational interface is manually manipulatable by a hand of an operator. One or more controllers control movement of the robotic manipulator to maintain the rotational axis of the surgical tool along a planned trajectory; autonomously control the surgical tool to rotate the screw at a rotational rate about the rotational axis and to linearly advance the screw at an advancement rate according to a known thread geometry of the screw; obtain a measurement indicative of a present interaction between the screw and the target site; and control the actuator of the haptic device to enable the rotational interface to emulate the present interaction between the screw and the target site.

Abstract: A biodegradable wellbore fluid with an oleaginous phase including a linear paraffin having 11-18 carbon atoms, a non-oleaginous phase, an emulsifying agent and optionally a weighting agent. Use of the fluid while drilling allows bio-remediation of drill cuttings using land spreading, bioreactors, conventional composting or vermiculture composting. The resulting product, especially when vermicomposed, is potentially useful as a soil amendment or plant fertilizer material.

Abstract: An applicator is provided with a volume for receiving one or more disposable or refillable container containing a hair treatment composition. The applicator is provided with opposed arms that are configured such that, when the arms are brought towards each other, the hair treatment composition is dispensed.
