A neurosurgery system for probing brain tissue of a patient for tumorous tissue. The system including a suction tool, an excitation source, an optical instrument, and a controller. The suction tool including a suction cannula defining a lumen, an optical fiber configured to transmit fluorescence emitted by the brain tissue; and an indicator configured to selectively emit visible light. An excitation source is configured to emit an excitation light having a wavelength to induce the fluorescence in the tumorous tissue. The optical instrument is coupled to the optical fiber. The optical instrument configured to convert the fluorescence emitted by the brain tissue and transmitted by the optical and configured to determine that the brain tissue is tumorous based on the electrical signal and activate the indicator based on the determination.

A computer-implemented method for displaying medical image data is provided. The method comprises receiving medical image data indicative of a patient anatomy having multiple connected parts that are movable relative to each other, creating at least two different bounding boxes in the medical image data so that each bounding box comprises image data indicative of at least one respective part of the patient anatomy not indicated by the image data of another one of the bounding boxes, and simultaneously displaying images, wherein each of the images is associated with a different one of the at least two different bounding boxes. A computer program, a carrier and a surgical planning system are also provided.

A fixation plate for securing bone fragments includes a first portion extending along a first longitudinal axis, a second portion extending from an end of the first portion along a second longitudinal axis such that the second longitudinal axis is at an angle of eighty to one hundred forty degrees relative to the first longitudinal axis, and first and second holes having respective first and second central hole axes that are substantially transverse to each other, wherein the first hole is disposed at a junction between the first and second portions, and the second hole is disposed at an end of the second portion opposite from the junction.

A medical device comprises a stem sized for insertion into a lumen of a coil; a stopper coupled to, and/or extending from, the stem. The stopper is proximal to a proximal end of the coil when the stem is inserted into the lumen of the coil and a structure outside the lumen of the coil. The structure defining an opening is sized to accommodate a distal portion of a delivery wire, and the stem comprises a channel configured to accommodate a first part of a stretch-resistant member when a second part of the stretch-resistant member is disposed around the structure that defines the opening.

A technique for automatic spinal cage planning is provided. In particular, a computer-implemented method 200 for automatically planning implementation of one or more spinal cages is provided. The method 200 comprises obtaining 210 image data including a 2D medical image comprising representations of a plurality of vertebrae of a patient's body in a standing body posture and determining 220 a 2D prediction image comprising representations of the plurality of vertebrae of the patient's body in the standing body posture, wherein determining the 2D prediction image comprises modifying the 2D medical image such that at least one spinal balance parameter derivable from the 2D prediction image fulfills a predefined criterion. The method 200 further comprises determining 230, based on the 2D prediction image, an implementation of one or more spinal cages yielding the poses of the vertebrae as represented by the prediction image.

A medical face mask is provided which includes a mask body having a mask interior and contoured to fit against the face of a patient. A permanently-open nasal aperture is provided in the mask body to facilitate insertion of an equipment, instrument or device into the mask interior and into the nose of the patient. A permanently-open oral aperture is provided in the mask body to facilitate insertion of an equipment, instrument or device into the mask interior and into the mouth of the patient. A one-way oxygen port is provided in the mask body to facilitate introduction of oxygen and/or medical gases into the mask interior of the mask body. A one-way valve port is provided in the mask body to facilitate discharge of carbon dioxide from the mask interior. A capnography or gas sampling port may be provided in the mask body to capture gases for analysis.

A computer-implemented method (1000) for supporting a surgeon in validating an implant placement, the method (1000) comprising: obtaining (S1010) preoperative patient image data comprising representations of a plurality of anatomical elements of a patient's body; obtaining (S1020) implant placement data indicative of a pose of at least one placed implant relative to at least one of the anatomical elements; obtaining (S1030) tracking data indicative of a change of a relative pose of at least one of the anatomical elements; determining (S1040), based on the preoperative patient image data, the implant placement data and the tracking data, a first simulated patient image comprising representations of the plurality of anatomical elements with the at least one of the anatomical elements having the changed pose, the simulated patient image further comprising a visualization of the placed implant; and triggering (S1050) display of the first simulated patient image to support the surgeon in validating the placement of the implant.

A balloon catheter which allows for faster preparation and effective purging of air. The balloon catheter includes an elongated, flexible catheter having an inner lumen. A balloon member is secured to an outer surface of a distal portion of the catheter such that an inner surface of the balloon member and an outer surface of the catheter define an inflatable balloon interior. The catheter has an inflation lumen connected to an inflation port and extending distally to a distal end in fluid communication with the inflatable balloon interior. One or more purge apertures are provided in a wall of the catheter, each forming a fluid path between the inflatable balloon interior and the inner lumen of the catheter to allow for purging air from the catheter prior to use in a medical procedure.
