A tissue sensing device for use with an electrosurgical knife is proposed which comprises a proximal end portion, a distal end portion and a grip portion there between. The proximal end portion is configured for attachment to a housing of the electrosurgical knife. The distal end portion is configured for movably supporting a blade of the knife. A distal end of an optical fiber is arranged at the distal end portion of the device and a proximal end of the optical fiber is connectable to an optical console, so that optical measurements can be performed at the distal end portion.

Optical tissue feedback device for an electrosurgical device

A biopsy device is provided comprising a tubular member, a hollow shaft and an elongated fiber body. The hollow shaft may have a distal end and a shaft, wherein a laterally (sidewardly) facing notch is formed in the distal portion of the shaft. The elongated fiber body may include at least one optical fiber, preferably at least two optical fibers, with a distal end. The tubular member is movable relative to the shaft, between a first position in which the notch is covered by the tubular member, and a second position in which the notch is not covered by the tubular member. The fiber body is movable within the shaft, between a first position in which the distal end of the optical fiber is located at the distal end of the shaft with the elongated fiber body extending through the notch, and a second position in which the distal end of the at least one optical fiber is located proximally to the notch.

System with photonic biopsy device for obtaining pathological information

A medical imaging system for identifying a target structure (TS), e.g. a tumor, in a biological tissue. A hyperspectral camera system is used for imaging a surface area (A) of the tissue (BT), e.g. with a limited spectral resolution, but enough to allow identification of suspicious areas where the target structure (TS) may be, e.g. such areas can be visually indicated on a display to the operator. A probe (PR), e.g. an optical surface probe, is used to provide probe measurement of a smaller surface area (A) of the tissue, but with more information indicative of the target structure. The probe is selected to provide a higher specificity with respect to identification of the target structure than the hyperspectral camera (HSC). The hyperspectral processing algorithm (PP) is then calibrated based on probe measurement data performed within the suspicious areas, thus providing a calibrated hyperspectral processing algorithm resulting in images with an enhanced sensitivity to identify the target structure. Only few probe measurements are required to significantly improve the resulting image, thereby providing a reliable and fast target structure (TS) identification.

Imaging system with hyperspectral camera guided probe

An active marker device () is introducible into a human tissue and for tracking a region of interest of a human body. The active marker device includes a light source () for emitting light such that the emitted light can be detected by an optical sensor. In this way, the active marker device and/or the region of interest can be tracked by a tracking system including the optical sensor. The active marker device () also includes a switch () for turning the light source on and off and for operating the light source in a pulsed mode.

Pulsed-light emitting marker device

The present invention relates to a method for determining a state of tissue sealing during a tissue sealing process. According to the disclosed method, an optical probe beam is used to irradiate a tissue region. A signal indicative of optical scattering in the tissue region is generated from a portion of the optical probe beam that has passed through or been returned by the tissue region. The onset of tissue sealing is indicated by the successive occurrence in time of a turning point and a point of inflection in the optical scattering signal. An energy-based tissue sealing or tissue-cutting device for use in accordance with the method is also disclosed.

A system and method to support exploring the interior of an object. The systemincludes a graphical user interface generator (GG) to generate a graphical user interface (GUI). The graphical user interface (GUI) includes an indicator (NC) of a current position of an interventional tool (IT) inside an object (OB). There is also an exploratory indictor (PC) to indicate material composition and/or type that surrounds the tool's tip (TP) at a current position in the object (OB). The exploratory indicator (PC) includes a pointer element for a current reading against a dial element for a range of possible values.

A biopsy device includes a tubular member, a hollow shaft and an elongated fiber body having at least one optical fiber. The hollow shaft has a laterally (sidewardly) facing notch in its distal portion. The tubular member is movable relative to the shaft, between a first position in which the notch is covered by the tubular member, and a second position in which the notch is not covered by the tubular member. The shaft is movable between a first position in which the distal end of the optical fiber is located at the distal end of the shaft with the elongated fiber body extending through the notch, and a second position in which the distal end of the at least one optical fiber is located proximally to the notch.

An interventional device, e.g. a Vacuum Assisted Biopsy (VAB) needle, incorporating optical fibers such that biological tissue in a volume at a side of the interventional device can be substantially completely optically probed by optical spectroscopy. In a VAB embodiment, a plurality of optical fiber pairs connected to respective optical ports, are placed at opposite positions along the suction cavity, and they are readout subsequently allowing to make a map of the tissue properties along the place where the tissue will be cut by the VAB needle. Based on decision software in an optical console, it can be determined whether the tissue present in the cutting cavity is completely normal tissue or not, prior to actually performing the biopsy on the tissue. In this way a well defined end point for VAB is created. In one embodiment, the optical fibers are arranged in a wall structure of a thin sleeve which fits onto existing VAB needles, thus allowing the VAB needle to be upgraded with an optical probing capability.

A biopsy device is proposed comprising a shaft and a tubular member. The shaft is movably, i.e. rotatably as well as shiftably accommodated within the tubular member and comprises a spiral at a distal end portion of the shaft, wherein the spiral is formed by a twisted sheet. Such a spiral may be considered as a laterally open thread having no solid core.
