Abstract: A computer assisted surgery apparatus includes a surgical instrument having an intervention member to cut tissue of a body part of a patient; a control unit arranged to control position and orientation of the intervention member in relation to the body part with regard to a predefined osteotomic line on the body part; and a tracking device arranged to track a position and orientation of the body part. The surgical instrument includes an optical monitoring system mounted in relation to the intervention member, wherein the optical monitoring system is arranged to continuously detect positions of marks applied to the body part, and the control unit is arranged to adjust position and/or orientation of the intervention member when a predefined deviation of the positions of the marks is detected. The surgery apparatus allows for application of cuts in the body part at comparably complex cutting geometries and at comparably high precision.

Abstract: Method for planning a process of cutting human or animal bone tissue. The method includes: obtaining initial data of an initial situation of the bone tissue; defining target data of a target situation of the bone tissue; and computing a cut geometry using the initial data and the target data for cutting the bone tissue apart. The cut geometry includes a structure such that the bone tissue is reassemblable at least in one degree of freedom in the target situation after being cut apart along the cut geometry. By shaping the structure of the cut geometry according to the target situation the planned cut can be provided with a particular function. Such a functional cut can geometrically define and restrict possible movements of cut apart bone portions. The functional cut can allow for comparably precisely repositioning the bone into the target position and any movement therefrom can be prevented.

Abstract: A siphoning group (10) for food waste disposers comprising a main duct (11) which can be connected upstream in a first end 11a with a food waste disposer and downstream in a second end 11b with a discharge tube, at least one derivation duct (12, 12?) connected to the main duct (11) between the upstream and downstream connections for the passage of water from at least another installation to said discharge tube, wherein the siphoning group (10) also comprises means for the selective isolation (13) of the at least one derivation duct (12, 12?) with respect to the main duct (11) during the use of the food waste disposer.

Abstract: A method for topically and systemically delivering a pharmaceutical composition to a human nail is disclosed, said method comprising the application of a pharmaceutical composition to the nail, covering the nail and the pharmaceutical composition with a protective layer, and a dissolvent to remove the protective layer and the pharmaceutical composition after a certain time of action and before reapplication. Preferably the method is combined with a laser pretreatment of the nail to drill arrays of partial orifices to enhance the permeability of drugs through the nail plate.

Abstract: A method for systemically delivering a pharmaceutical composition to a human or animal, said method comprising forming an orifice in a nail of a human or animal by means of a laser-based device and applying a pharmaceutical composition in the orifice, wherein said method provides a controlled release of the pharmaceutical composition.
