Abstract: Systems, devices, and methods for identifying different structure types with distinct composition in vivo and adjusting surgical laser output accordingly in a medical procedure are disclosed. An exemplary laser treatment system comprises a laser system configured to generate a laser beam for delivery to a target in a body, and a controller circuit configured to receive a signal reflected from the target in response to electromagnetic radiation produced by a light source, and generate one or more spectroscopic properties from the reflected signal. The controller circuit can identify the target as one of a plurality of structure types, such as tissue types or calculi types with respective compositions, using the one or more spectroscopic properties. The laser system can be controlled to operate in an operating mode based on the target identification.

Abstract: A laser can produce pulses of light energy for tissue-type selective ejection of a volume of the target tissue, and the energy can be delivered to a treatment site through a waveguide, such as a fiber optic waveguide. The incident laser energy can be absorbed within a volume of the target tissue with a tissue penetration depth and pulse direction such that the propagation of the energy from the tissue volume is inhibited and such that the target tissue within the volume reaches the spinodal threshold of decomposition and ejects the volume, for example without substantial damage to tissue adjacent the ejected volume. The pulses are set to be tissue selective.

Abstract: A control device is a control device for an energy treatment tool including a first holding member and a second holding member which hold a biological tissue, and a heating element configured to generate heat corresponding to supplied power, thereby heating a holding surface. The control device includes a temperature acquiring section that acquires a temperature of the heating element; and a surface temperature estimating section that estimates, as a surface temperature, a temperature of at least a part of a surface of the first holding member which is different from a portion facing the second holding member, based on a change of the temperature of the heating element after supply of the power is stopped.

Abstract: An apparatus includes a shaft assembly. A sliding electrical coupling provides electrical continuity between components of the shaft while permitting movement of a second shaft component relative to a first shaft component at the joint. An end effector is positioned at a distal end of the shaft assembly and is operable to engage tissue of a patient. A sensor is positioned adjacent to the joint and is configured to measure a joint parameter indicating a state of the sliding electrical coupling. The sensor transmits a first signal indicative of the measured joint parameter to a control module. The control module determines whether the measured joint parameter exceeds a maximum deviation from a predetermined value. When the measured joint parameter exceeds a maximum deviation from a predetermined value, the control module initiates a responsive action.
