Definitions
- the present invention relates to a device and a method for obtaining 3D ultrasound data, in particular for imaging in the field of minimally invasive surgery during neurosurgical interventions.
- image-based surveillance of the operating area during a surgical procedure is an important aid.
- intraoperative monitoring can only be carried out today with considerable expense or considerable additional strain on the patient.
- X-ray computed tomography is known as another method of imaging in medicine. However, due to the resulting radiation exposure for surgeons and patients, this method cannot be used in the area of intraoperative imaging.
- Another imaging technique using ultrasound has so far only been able to be used continuously during operations on the open skull.
- the ultrasound device In the case of minimally invasive surgery, on the other hand, the ultrasound device must alternately be guided through a trepanation hole with the use of the surgical instruments, so that the guidance of the surgical instruments cannot be observed during the operation.
- the present invention is therefore based on the object of specifying a device and a method for obtaining 3D ultrasound data, in particular for imaging during neurosurgical interventions, with which data for image display of the operating area are continuously obtained during a minimally invasive intervention on the brain become.
- the device should also be inexpensive to implement.
- the ultrasound transducer can be inserted and placed through the surgical opening (trephination hole) at the beginning of the procedure.
- the ultrasound transducer can remain in its position during the entire duration of the operation, so that a permanent scanning of the operating area - including the instruments - and its visual representation are made possible.
- the operation can thus be tracked on the screen during a minimally invasive procedure using simple means without using extremely expensive and complex magnetic resonance tomographs.
- the use of the device and the method is not limited to neurosurgical interventions.
- the invention can initially be used in all minimally invasive interventions. Even in the non-medical field, in processes in which there is only limited access to areas to be imaged through small openings, and in which simultaneous access to the imaging and operating system is desired, the use of the device and the method offer corresponding advantages.
- the imaging can be given when working on machine parts that are difficult to access in the area of mechanical engineering.
- a device with one or more extremely flat ultrasound transducers is used, which can be located laterally next to the trepanation hole between the dura mater and the brain and can remain there during the operation without access through the
- the converter is fixed via a connecting web connected to the fixing device, which is thus connected to the
- transducer Connected transducer is that the transducer can be pushed laterally under the dura mater after insertion through the trephine hole.
- the imaging device comprises at least one ultrasound transducer, a fixing device for locally fixing the ultrasound transducer relative to the region to be imaged, and a connecting web which connects the ultrasound transducer to the fixing device.
- the connecting web is with an edge area of the
- Ultrasonic transducer connected and forms an essentially perpendicular angle with the transducer plane.
- the angle is chosen so that the function of the device to keep large areas of the opening free even after the transducer has been inserted is ensured.
- the thickness of the layer in which the opening is present plays a role in this. For thin layers, there is a greater deviation from the 90 ° angle (e.g. angle between 70 ° and 110 °) acceptable than for thicker layers.
- the inner (geometric) shape of the layer as explained below, can also influence the possible angular range.
- an angle above 90 ° preferably between 90 ° and 100 °, can be advantageous, in particular due to the spherical skull cavity, so that the ultrasound transducer lies completely against the top of the skull after insertion.
- the dimensions of the ultrasound transducer are selected such that it can be inserted into a trephine hole in the skull of a patient and inserted between the meninges and the brain.
- a trepanation hole usually has a diameter of 15 to 25 mm.
- the thickness of the connecting web is chosen so that the connecting web only a small part, i.e. less than 25% of the cross-section of the trephine hole covered.
- the connecting web advantageously has a maximum thickness of 3 mm and a length of approximately 15-20 mm.
- the dimensions of the ultrasonic transducer are preferably at most 3 mm perpendicular to the transducer plane (thickness of the transducer).
- the fixing device can be formed by a converter shaft, for example in the form of a handle.
- this fixing device for fixing the ultrasound transducer is rigidly connected to the fixing device for the patient's head.
- the connecting bridge has the function of mechanically connecting the ultrasonic transducer to the fixing device and to be electrically connected to the primary electronics and / or the evaluation electronics. It must therefore be suitable for accepting electrical connections (eg thin wires or conductor tracks). Furthermore, it must be mechanically stiff enough to ensure a rigid connection between the transducer and the fixing device, so that blur-free images of the area to be imaged can be delivered.
- the connecting web is as flat or thin as possible so that it only fills the opening to a small extent. Preferred dimensions of the connecting web for use in neurosurgical interventions are given in the exemplary embodiment.
- the ultrasonic transducer itself preferably has a coin-like shape with a thickness of less than 1 cm. It is connected via the connecting web to primary electronics (e.g. amplifiers, multiplexers, etc.), which is provided in the region of the end of the connecting web opposite the ultrasound transducer.
- the primary electronics can, for example, be integrated in the converter shaft. However, it is also possible to integrate at least part of the primary electronics in the ultrasound transducer itself.
- the signals obtained by the ultrasound transducer are forwarded to an image processing unit, so that they can be displayed on a monitor, for example.
- the ultrasound transducer preferably consists of a plurality of transducer elements arranged in an array in one plane, which form an electronically controllable two-dimensional phase array.
- the entire area to be imaged can be scanned with the ultrasound beam by controlling the individual transducer elements with a phase shift. This way it is possible without mechanical Movement of the transducer to obtain the data for a complete picture of the area to be imaged.
- the ultrasound transducer can also be designed as an electronically controllable linear array. If this linear array is arranged in a thin tube, the array can be pivoted about its longitudinal axis by a mechanical drive. This also scans the entire area.
- a device with an ultrasound transducer which is connected to a fixing device via a thin connecting web and forms an angled shape with the connecting web.
- An example of such a device is the subject of claim 1.
- the device is inserted through the opening, pushed laterally next to it below the opening, fixed by means of the fixing device and subsequently operated to provide data for the image display of the area. Due to the special shape of the device, the majority of the opening for the introduction of further devices remains accessible almost without hindrance after it has been fixed.
- Fig. 1 shows an example of a device for imaging according to the invention in side view
- FIG. 1 shows a side view of an example of the imaging device (1) according to the invention, in which a miniaturized ultrasound transducer (2) is connected to a transducer shaft (4) via a connecting web (3).
- the electronics (5) close to the transducer are attached to the transducer shaft (4).
- This electronics includes the primary electronics (preamplifier,
- the ultrasonic transducer is connected to an image processing / image display unit (not shown) via the connecting web, the transducer shaft with the primary electronics and a connecting cable (6).
- image processing / image display unit not shown
- the flat shape of the ultrasonic transducer (2) can be clearly seen, on the edge of which
- Connecting web (3) is attached perpendicular to the transducer level, so that the connecting web and transducer together form an "L" shape.
- the connecting web (3) is also very flat in this side view.
- the ultrasound transducer preferably has a diameter or a width / length of approximately 20 mm and a maximum thickness of 3 mm.
- the connecting web here preferably has a length of approximately 15-20 mm, a width of approximately 10-15 mm and a thickness of 2-3 mm.
- the converter material as well as the material of the connecting web are of course selected in terms of biocompatibility and sterilizability.
- Figure 2 shows the use of this device in a minimally invasive procedure on the brain (7) of a patient.
- a trephination hole (8) is first made, which penetrates the scalp (9), the skull bone (10) and the meninges (11, dura mater).
- the surgical instruments (12, eg endoscope, ..) are guided through the trepanation hole (8) to the brain (7).
- the ultrasound transmitter (2) of the device (1) is guided through the trepanation bore (8) before the start of the operation or of the section of the operation to be observed and is pushed flat to the side of the bore between the brain (7) and the meninges (11).
- the device remains there during the operation, so that ultrasound data from the operating area can be continuously supplied and used for image display on a monitor. Due to the mutual arrangement and shape of the connecting web (3) and ultrasound transmitter (2), the majority of the trepanation opening (8) remains free in this case, so that the introduction of the surgical instruments is not hindered.
- the ultrasound transducer can be implemented as a purely electronically controllable phase array, a matrix-like arrangement of many small elementary transducers. With such an ultrasonic transducer, free control of the direction of the ultrasound can be achieved without mechanical movement of the transducer.
- the phase array can be dimensioned so large that it is almost the entire insertion Cross-section of the trepanation opening claimed, but then disappears laterally under the meninges.
- the ultrasound transducer can also be implemented as a linear array a few millimeters wide, which enables two-dimensional scanning. Arranging the transducer in a thin tube enables the linear array to be pivoted perpendicular to its scanning plane. The volume of interest can thus also be completely scanned. In a preferred embodiment, this
- the device and the method according to the invention can also be used in other surgical techniques.
