The elongate shaft has a circular outer cross section with a first diameter (D), a distal end () for insertion into bone, a proximal end (), and an optical connector portion () disposed towards the proximal end (). The at least one optical fiber () extends within the elongate shaft () between the optical connector portion (), and the distal end () for transmitting optical radiation between the optical connector portion () and the bone region () when the distal end () is inserted into the bone region (). The optical connector portion () comprises a reduced-diameter portion (). The reduced-diameter portion () extends along at least a portion of the elongate shaft (), and has an outer cross section comprising a width (Drd) perpendicularly with respect to the elongate shaft (). The width (Drd) is less than the first diameter (D).

Orthopedic pin for optically analyzing a bone region

The application relates to the problem of navigating a surgical instrument (at) towards a region-of-interest (at) in endoscopic surgery when an image () provided by the endoscope is obscured at least partly by obscuring matter (at), wherein the obscuring matter is a leaking body fluid, debris or smoke caused by ablation. To address this problem, a computer-implemented method is proposed, wherein, upon detecting that the image from the endoscope is at least partly obscured, a second image is determined based on a sequence of historic images and based on the current position and orientation of the endoscope. Furthermore, a virtual image () is generated based on the determined second image.

The invention relates a system for implanting an implantable device in bone tissue, a processing unit for such system, a method of implanting an implantable device and a method of providing information for an implanting of an implantable device. In view of the finding that a fat content in cancellous bone is higher than a fat content in compact bone, the lipids fraction, which can be determined by optical means, e.g. spectroscopy, can be used to determine correct screw placement in healthy bone.

System for implanting in bone tissue

A system is suggested comprising an optical sensing means and a processing unit. The optical sensing means may include an optical guide with a distal end, wherein the optical guide may be configured to be arranged in a device to be inserted into tissue in a region of interest. The processing unit may be configured to receive information of a region of interest including different tissue types as well as of a path through the tissues, to determine a sequence of tissue types along the path, to determine a tissue type at the distal end of the optical guide based on information received from the optical sensing means, to compare the determined tissue type with the tissue types on the path, to determine possible positions of the distal end of the optical guide on the path based on the comparison of tissue types, and to generate a signal indicative for the possible positions.

A system may generally comprise a tracking device, an ultrasound device and a processing unit. A position and orientation of the ultrasound device may be traceable by the tracking device. The processing unit may be configured (i) to receive 3D information of a region of interest in relation to a marker, with both the region of interest and the marker being located within a body, (ii) to determine the position of the marker relative to the ultrasound device based on an ultrasound image of the body including the marker, and (iii) to determine the position and orientation of the ultrasound device relative to the tracking device. The system may further comprise a visualization device and the processing unit may further be configured to generate a visualization of the region of interest in relation to an outer surface of the body.

A method of analyzing a tube system in particular by image processing of images of the tube system is provided by the present invention. In order to achieve a simulation of a medium flow through a calculated tube model, the present invention gathers a tube model from a specific tube data set. By defining the necessary parameters of a virtual injection of the medium by the user, the medium flows through the model. Using this displayed simulation for generating at least two images leads to an artificial image sequence that might support a person, which wants to examine a real structure, that corresponds to the calculated model. This might be seen in.
