A medical supporting arm according to the present disclosure includes a supporting arm and a calculation unit. The supporting arm supports an oblique-viewing endoscope. The calculation unit calculates a rotation angle of the oblique-viewing endoscope around an axis in a longitudinal direction, and an insertion amount of the oblique-viewing endoscope into a human body on the basis of a first expression that defines coordinates of a subject in a coordinate system in which an insertion opening allowing the oblique-viewing endo scope to be inserted into the human body serves as an origin, and a second expression that defines the coordinates of the subject positioned in an optical axis direction of an objective lens disposed at a distal end of the oblique-viewing endoscope in a coordinate system in which the distal end of the oblique-viewing endoscope serves as an origin.

Systems and methods are presented for monitoring brain pulsatility. A change in volume of the brain is estimated based at least in part on an output of a non-contact, surface measuring sensor (e.g., a distance sensor or a camera). A metric indicative of brain pulsatility is then calculated based at least in part on a ratio of the estimated change in volume of the brain relative to a change in arterial blood pressure.

A solution is proposed for assisting a medical procedure. A corresponding method comprises acquiring a luminescence image (205F), based on a luminescence light, and an auxiliary image (205R), based on an auxiliary light different from this luminescence light, of a field of view (103); the field of view (103) contains a region of interest comprising a target body of the medical procedure (containing a luminescence substance) and one or more foreign objects. An auxiliary informative region (210Ri) representative of the region of interest without the foreign objects is identified in the auxiliary image (205R) according to its content, and a luminescence informative region (210Fi) is identified in the luminescence image (205F) according to the auxiliary informative region (210Ri). The luminescence image (205F) is processed limited to the luminescence informative region (210Fi) for facilitating an identification of a representation of the target body therein. A computer program and a corresponding computer program product for implementing the method are also proposed. Moreover, a computing device for performing the method and an imaging system comprising it are proposed. A medical procedure based on the same solution is further proposed.

An object of the present invention is to provide a new electric device for defibrillation and a method for generating a defibrillation signal. The electric device for defibrillation includes an electrocardiogram waveform input unit; and an enable signal generating unit, wherein the electric device for defibrillation is configured to generate an enable signal from the enable signal generating unit after a peak of an event is surpassed and when or after condition 1 is satisfied, the event being estimated to be an R-wave of an electrocardiogram waveform, the electrocardiogram waveform being obtained from a human body and inputted from the electrocardiogram waveform input unit, and the condition 1 is that a differential value in a differentiated waveform generated based on the electrocardiogram waveform, which corresponds to the event estimated to be the R-wave, is a negative constant C.sub.3 value or less.

Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have a pontoon shape with opposed elongated partially cylindrical sections connected by a bridge section. The partially cylindrical sections and, in some instances, the bridge section have a porous structure.

The endoscope has an insertion portion, an imaging unit, and a member formed in a given dimension. The insertion portion has an apical portion, an actively curvable portion, and a treatment device channel. The actively curvable portion is located on the proximal side of the apical portion. The treatment device channel is positioned along the longitudinal axis of the insertion portion. The insertion portion is formed of resin. One or more radiopaque members, formed of knowns dimensions, are coated on a surface of the insertion portion or placed in, buried or covered laterally in the insertion portion. The X-ray transmittance of the radiopaque members is different from the X-ray transmittance of the resin forming the insertion portion.

A thulium fiber laser system can be used to treat tissues based on the ability for quick changes between laser pulses. For example, to treat stones in a tissue, a long pulse having low peak power can be used to create bubbles in front of the stone (calculi), then follow a series of shorter pulses and higher peak power can be used to break the stone. The sequence can be repeated to maintain large bubble formation, with the long pulse characteristics changed to accommodate for the changes in the tissue. A fluorescent sensing assembly can be used to detect the tissue conditions for selecting the conditions of the thulium fiber laser.

The present invention relates to a suction instrument, more particularly a bipolar mapping suction instrument, for surgical purposes and to a system for suctioning fluids and tissue and for monitoring nerve tissue. The suction instrument comprises a cannula unit, which comprises an electrically conductive outer cannula tube, an electrically conductive inner cannula tube, and insulation. The electrically conductive inner cannula tube is electrically connected to a first pole of the bipolar electrical connection of the second interface. The electrically conductive inner cannula tube is arranged concentrically in the outer cannula tube which optionally can be insulated from the exterior. The electrically conductive inner cannula tube is mechanically connected to the handpiece and/or the first interface. The electrically conductive outer cannula tube is electrically connected to a second pole of the bipolar electrical connection of the second interface. The insulation is concentrically arranged between the outer cannula tube and the inner cannula tube. The insulation is configured to fully electrically isolate the outer cannula tube and the inner cannula tube in relation to one another.

In a medical or surgical equipment for receiving signals or for outputting signals from or to organic signal transmitters or receivers (4), such as in particular nerves, wherein on or in at least one carrier strip (1) at least one signal transmitter (2) for signals from or signals to the organic signal transmitter or receiver (4) is provided, which can be brought into contact with the organic signal transmitter or receiver (4), the carrier strip (1) is intended to change its shape when there is a change in a medium surrounding it or in a medium present in it or by a medium that can be introduced into it, in such a way that it adapts to the organic signal transmitter or receiver (4).

A hemodynamic monitoring system monitors arterial blood pressure of a patient and provides a warning to medical personnel of a predicted future hypotension event of the patient. Waveform analysis is performed on sensed hemodynamic data representative of an arterial pressure waveform of the patient to determine a plurality of hypotension profiling parameters predictive of a future hypotension event for the patient. A set of transformed hypotension profiling parameters is generated based on the hypotension profiling parameters and mean and standard deviation values of the hypotension profiling parameters at a standard mean arterial pressure (MAP) threshold for hypotension and an adjusted MAP threshold for hypotension. A risk score representing a probability of a future hypotension event for the patient is determined based on the set of transformed hypotension profiling parameters. A sensory alarm is invoked to produce a sensory signal in response to the risk score satisfying a predetermined risk criterion.
