Definitions
- the invention relates to a method for the non-invasive determination of the position and orientation of distinctive structures in the interior of a human or animal body, in which the body in the area of the distinctive structure is irradiated with ultrasound radiation by means of an ultrasound head which emits and receives ultrasound, the reflective structure being reflected Receives ultrasound radiation and displays an image corresponding to the transit time of the reflected radiation on a display.
- the invention further relates to an apparatus for performing this method.
- a disadvantage of this method is that an opening of the body is necessary, if one feels such structures through soft tissue, inaccuracies can occur.
- ultrasound radiation is directed into the body via an ultrasound head, is reflected there by striking structures, and the reflected radiation is picked up again by the ultrasound head.
- the distance of the reflection surfaces from the ultrasound head can be determined from the transit time, and the position of the distinctive structures can also be determined from the beam direction of the ultrasound head.
- the shape of the striking structures can be recorded and displayed in this way, but it does not provide precise information about the position and orientation relative to the body.
- This object is achieved according to the invention in a method of the type described at the outset by determining the position and orientation of the ultrasound head and the body in the region of the striking structure with the aid of marking elements fixed on the ultrasound head and on the body by means of a navigation system, that one on the display selects a striking structure, determines the position and orientation of the striking structure relative to the ultrasound head based on the beam direction of the ultrasound head and the measured transit time of the ultrasound radiation, and determines the position and orientation of the striking structure relative to the body from the position and orientation of the ultrasound head relative to the body.
- the ultrasound head provides information about the direction of the Ultrasound radiation and the distance of the reflecting surface from the ultrasound head, and this direction of the ultrasound head is connected to the position and orientation of the ultrasound head, which is determined via the navigation. In this way, all necessary data is obtained to determine the position and orientation of the reflecting surface and thus the striking structure in the body relative to the body.
- An opening of the body as is the case when using navigated buttons, is no longer necessary; the ultrasound head takes on the role of a "virtual button".
- an ultrasound head which emits or receives ultrasound radiation via a multiplicity of transmitting and receiving devices which are arranged in a row and emit the ultrasound radiation in a common plane.
- a complete level is scanned with ultrasound radiation at the same time, and the operator can align the ultrasound head when the ultrasound head is placed on the body in such a way that the striking structure to be detected is optimally depicted on the display, ie is clearly visible.
- This automatically leads to the fact that the ultrasound head is positioned practically always in the same way relative to a certain structure, for example always in such a way that the ultrasound head runs parallel to a iliac crest. This ensures a largely reproducible scanning of the striking structure with the ultrasound radiation.
- the operator can select certain characteristic points on the image, for example by moving to an optical marking and storing the corresponding position data of this marking. In some cases, however, this is not easily possible since the structures shown do not allow the selection of a specific exact point. It is then advantageous if you match the striking structure on the display with a given geometric structure as well as possible and determine structural data of the striking structure of the body from the position of the given geometric structure on the display.
- Such a predefined geometric structure can be, for example, a straight or a curved line, in particular it can be a circle, for example, which is adapted to an approximately circular structure of the display in such a way that the best possible overlap takes place, possibly also only in one certain sub-area of the given geometric structure.
- a sphere with the circle of the given structure is determined as a large circle as the structural data of the given geometric structure. This sphere is used to characterize a certain distinctive structure.
- the described method can be carried out at various points on the body.
- the left and right iliac crests and additionally the symphysis of the hip bone are selected as the distinctive structure.
- one of the two pelvic crest images and the symphysis image on the display each determine a prominent point and use these three points to calculate a plane characteristic of the hip bone.
- the characteristic level can be selected such that there is a characteristic point of the symphysis that can be determined directly from the display, and that the two pelvic ridges are assigned balls in the manner described above, on the surface of which the characteristic see level is present.
- a level can be referred to as the characteristic level of the hip bone; this level can serve, for example, as the basis for the geometric description of the hip bone and the choice of a coordinate system that is fixed to the hip bone.
- the invention is also based on the object of proposing a device for carrying out this method.
- a device for the non-invasive determination of the position and orientation of distinctive structures in the interior of the human or animal body in that it has an ultrasound head for emitting and receiving ultrasound radiation and a display for displaying the duration of a transmitted, Image corresponding to ultrasound radiation reflected on a striking structure of the body comprises that marking elements for the ultrasound head and the body are provided, which are part of a navigation system, and that a data processing system is provided which is based on the relative position and orientation of the ultrasound head to the body and the Beam direction of the ultrasound head and the measured transit time of the ultrasound radiation determine the position and orientation of a striking structure shown on the display relative to the body.
- the ultrasound head emits or receives the ultrasound radiation via a multiplicity of transmitting and receiving devices which are arranged in a row and emit the ultrasound radiation in a common plane.
- Figure 1 is a schematic view of a navigated mechanical button for scanning distinctive structures in the body according to the prior art
- FIG. 2 shows a schematic view of a navigated ultrasound head in contact with a pelvic crest of the hip bone with an associated representation of the image supplied by the ultrasound head on a display;
- Figure 3 a view similar to Figure 2 with the ultrasound head in contact with the other iliac crest;
- Figure 4 a view similar to Figure 2 with the ultrasound head in contact with the symphysis of the hip bone;
- FIG. 5 shows a schematic representation for evaluating the illustrations in FIGS. 2 to 4 and for determining a plane characteristic of the hip bone;
- Figure 6 a view similar to Figure 2 with the application of the ultrasound head on a femur and
- FIG. 7 shows a view similar to FIG. 2 with an ultrasound head placed on the ankle.
- FIG. 1 shows a conventional device for mechanically scanning a striking structure of the body.
- This submission includes a mechanical button 1, on which a marking element 2 of a conventional navigation system 3 is fixed, this navigation system 3 comprises a plurality of transmitting and receiving units 4 which emit electromagnetic radiation which reflects on reflectors 5 of the marking element 2 and from the transmitting and Receiving units 4 is caught again. From these signals, the navigation system 3 can determine the exact position and orientation of the marking element 2 and thus of the button 1 in space in a manner known per se. The corresponding position data are fed to a data processing system 6.
- marking element 7 which is constructed in the same way as the marking element 2, is attached to a part of the body 8, the striking structure of which is to be determined.
- the marking element 7 is fixed on a hip bone 9, for example by means of a bone screw screwed into the hip bone 9.
- Such marking elements are usually used for operations and are then used to determine the position and orientation of the corresponding body part during an operation.
- the navigation system 3 can determine both the position and orientation of the button 1 and the position and orientation of the body part where a structure is to be located.
- This localization takes place in the device described in FIG. 1, which corresponds to the known state of the art, by placing the tip of the push button 1 on the corresponding structure, for this purpose the body must be open, the corresponding structure must be exposed.
- an ultrasound head 10 is used instead of a mechanical probe, which is known per se for examining structures inside the body and which is provided by means of a contact surface 11 on the outside of the body Body can be put on.
- Such an ultrasound head 10 emits ultrasound radiation, for example, via a plurality of transmitting and receiving units which are arranged in a row, into a plane common to all transmitting and receiving units and receives ultrasound radiation reflected from internal body structures, which is reflected back in this plane.
- the distance between the reflecting surface on the inner structure of the body and the ultrasound head 10 can be determined from the transit time between emitting and receiving the radiation, and these data are fed to the data processing system 6.
- the marking element 2 is attached to the ultrasound head 10, so that the position of the ultrasound head and its orientation are determined by the navigation system 3.
- the pattern generated by the ultrasound head 10 is displayed on a screen 12 so that the operator can read off the relief pattern of the ultrasound radiation, that is to say the transit time measurements of the ultrasound radiation, on the screen 12.
- This pattern shows certain structures that result from the structure of the surface reflecting the ultrasound radiation, for example a bone surface.
- FIGS. 2 to 4 are used to discuss how certain structures of the hip bone can be determined in this way and how these structures can be used to characterize the hip bone.
- the ultrasound head 10 is first placed on the body 8 on one side of the hip bone 9 such that it is essentially aligned with the iliac crest 14.
- the surgeon can make the exact alignment on the basis of the display on the screen 12, since the alignment with the iliac crest 14 results in a particularly sharp and clearly recognizable structure, so that the ultrasound head can be placed reproducibly on the hip bones 9 of different patients.
- the ultrasound head is placed in the middle of the hip bone 9 at its lower end in the area of the symphysis 18, a clear downward pointing tip 19 is obtained on the screen 12, which reflects the structure of the symphysis.
- the data processing system places through the two circles 20, 21 a sphere which has the same center and the same radius as the circles, so that the circles form large circles.
- the data processing system then calculates from the position of the point 22 on the one hand and the balls determined in this way on the other hand a plane in which the point 22 lies and which lies tangentially against the two balls (FIG. 5).
- a point of each iliac crest 14 lies in this plane, since the circles 20, 21 were placed on the arcuate regions 15, 17 of the iliac crest, so that this also applies to the ball.
- a level is thus determined, which contains a point of each iliac crest and the point determined on the symphysis, such a level is a characteristic level for the position and orientation of the hip bone, and this level can be used to enter a further course of the operation to determine the hip bone's own coordinate system and to perform the necessary positioning of implants, processing tools etc. relative to the hip bone.
