A surgical forceps comprises a first jaw () and a second jaw (), the first jaw () and the second jaw () being configured to be rotated relative to each other around an axis of rotation (). A position sensor () is capable of sensing a first orientation with respect to a first axis () and a second orientation with respect to a second axis () different from the first axis (), wherein the first axis () and the second axis () are orthogonal to the axis of rotation (). The surgical forceps comprises a stapler () for stapling a tissue grasped by the surgical forceps () and a cutter () for cutting the tissue grasped by the surgical forceps () along a line.

A magnetic marker for use in locating tissue for surgery includes a casing and two to five magnetic elements arranged in a row. The two or more magnetic elements are separated from each other by an isolating material. The magnetic marker may be non-bio-absorbable. This means that the magnetic marker is invariable as it does not decay over time. This invariability ensures that on the basis of the signal measured by a magnetometer device a distance between a probe of the magnetometer device and the magnetic marker can be determined.

In a method and system for providing visual information about a tumour location in human or animal body, an electromagnetic tumour sensor is provided in the tumour and tracked to determine its location in space, which is mapped to a tumour model. A surgical tool sensor is provided on a surgical tool, and tracked to determine its location in space, which is mapped to a surgical tool model. The body is scanned to obtain information about an anatomical structure. A reference sensor is provided on the body, and tracked to determine its location in space, which is mapped to the anatomical structure. A virtual image is displayed showing the tumour model, located with the at least one tumour sensor, in spatial relationship to the surgical tool model, located with the at least one surgical tool sensor, and the anatomical structure, located with the at least one reference sensor.

In a method and apparatus, a property of an optically diffuse medium including a first optical absorber having a first concentration and a second optical absorber having a second concentration is determined. A surface area of the medium is imaged at multiple wavelengths around an isosbestic wavelength of the first absorber and the second absorber. A reflectance spectrum of the medium at the surface area at the multiple wavelengths is determined. A derivative of the determined reflectance spectrum around the isosbestic wavelength is determined. From the derivative, a concentration ratio of the first concentration and the second concentration is estimated.
