摘要:
The invention relates to a control system for a surgical navigation system, wherein the navigation system is associated with a detection unit for detecting system control inputs made by a user, and wherein the navigation system is controlled in accordance with the control inputs and the detection unit comprises a gesture detection for detecting user gestures. The invention also relates to a method for controlling a surgical navigation system, wherein a detection unit for detecting system control inputs made by a user is associated with the surgical navigation system, the navigation system is controlled in accordance with the control inputs, and user gestures are used as said control inputs.
摘要:
The invention relates to a medical instrument, comprising a signal transmitter and at least one activating device for activating the transmitter which is provided on a transmitter unit which is separate from the instrument, wherein the transmitter unit is a unit which can be fastened to the exterior of the instrument. It also relates to a method for controlling a treatment-assisting medical software by means of a signal transmitter which is arranged on a medical instrument, wherein the instrument is positionally detected by means of a medical tracking system, and wherein the software assigns a different significance to the signal output by the transmitter depending on the position of the instrument.
摘要:
The invention relates to a method for visually assisting the alignment of a medical instrument, wherein the instrument is visually displayed on an image output in a positional relationship to a part of a patient's body by means of a medical navigation system, wherein an orientation aid is displayed as a virtual model shape at the instrument or in a particular positioning with respect to a characteristic part of the instrument. It also relates to a planning method for optimized instrument alignment with the aid of such an image assisting method.
摘要:
The invention relates to an instrument for use in computer guided surgery. The instrument includes a shaft and a reference element adapter, wherein the reference element adapter is directly couplable to the shaft and rotatable about the shaft. A selectively operable mechanical retainer provides retention of the reference element adapter to an instrument shaft adapting interface of the instrument shaft. The instrument also includes a reference element orientating mechanism arranged at an interface between the instrument shaft adapting interface and the reference element adaptor. The reference element orienting mechanism is capable of fixing at least one angular position of the reference element. The instrument also includes a grip piece interface on the instrument shaft, and a grip piece is selectively couplable to the grip piece interface.
摘要:
A protective body for insertion into a body cavity of a human or animal body for the protection of tissue and/or organs that are not to be irradiated when carrying out radiation therapy, wherein the protective body (1) includes at least one absorber body (2) designed to absorb radiation and having at least one curved surface (3) that delimits the absorber body, and the absorber body (2) has a density at 20° C. of at least 5 gram per cubic centimeter, preferably of at least 10 gram per cubic centimeter.
摘要:
The invention relates to expandable polystyrene (EPS) comprising polyolefin waxes, wherein the latter have been prepared by means of metallocene catalysts and have a drop melting point or ring/ball softening point of from 80 to 165° C. and a melt viscosity measured at a temperature which is 10° C. above the drop melting point or softening point of from 20 to 10 000 mPa·s.
摘要:
The invention relates to mixtures of phosphonite (component A) and/or an ester and/or salt of a long-chain fatty acid (component B), and/or a carboxylic ester, and/or carboxylic amide (component C), and also to their use in polyamides or in polyesters.
