Implementation of the invention

The imaging system for medical purposes includes at least one miniature camera 2.1...2.n placed on the object for shooting, transmitting information to the processing device 4, and then to at least one video signal display device 5, and the system contains also control unit 3.

The visualization system may further comprise a general plan camera 1 transmitting information to the processing device 4 . The camera 1 can be located above the patient's head and, depending on the viewing angle, can show both the actions of the doctor and the general situation in the operating room. Various mounting options are acceptable: tripod, camera crane, separate stand (see photo in Fig. 9), ceiling mount, etc.

The miniature camera 2 also transmits the video signal and sensor data to the video signal processing device 4 . Each miniature camera 2.1…2.n contains a gyroscope, an accelerometer, a lighting system, interchangeable lenses and is fixed on the subject using an articulation hinge 7. For example, a Protium model camera can be used as such a miniature camera.

The articulatory hinge 7 is (see Fig. 6) an articulating bar, consisting of two pressure plates 7.2, a pressure screw 7.1 and two bolts 7.3 with spherical caps. When the clamping screw 7.1 is unclenched, the bolts 7.3 receive a greater degree of freedom due to the ability to rotate in the corresponding grooves of the clamping plates 7.2. After selecting a suitable angle for shooting, the clamping screw 7.1 is tightened, the bolts 7.3 are fixed in the selected positions and securely fix the camera 2.

Object options for shooting can be the following: handpiece base, quick-release mount, micromotor, tool handle, etc. The figures show the following options: fastening with a universal handle 9 with replaceable working nozzles 6 (see Fig. 3-4) and a quick-release fastener in the form of a fixing ring 14, which is attached to the micromotor 15 of the physiodispenser (see Fig. 7-8) .

The universal handle 9 (see Figs. 3-4) is equipped with threaded grooves for fixing the articulatory hinge 7 and the camera 2. The working nozzle 6 is changed by turning the fixing nut 8.

Replaceable working nozzles 6 have an identical working section 12 (see Fig. 5), that is, when installed in the handle 9, the working part of the tool will always be removed from it at the same distance. This feature makes it possible not to change the focal length of the camera 2 when changing the attachment. The working part of any interchangeable attachment 6 will always be in focus. The hexagonal index 13 at the base of the nozzle allows the tool to be set in a reproducible position, thus ensuring the repeatability of the position of the tools when changing.

To fix the chamber 2 to the micromotor 15 of the physiodispenser or the micromotor of another instrument, a fixing ring 14 (see Fig. 7-8) can be used, which consists of two metal parts in the form of half rings with special mounting holes and grooves. With the help of bolts, two half-rings are interconnected, securely clasping the attachment area on the selected tool. Further, articulation hinges 7 and/or adapters for mounting the camera 2 directly can be installed in one or more mounting holes and/or grooves.

Cameras 2 can be fixed either on two handpieces at the same time (on a surgical micromotor and on an ultrasonic handpiece, for example), or on a handpiece and on a special hand tool, or in any other combination.

In FIG. 4 and 7 schematically show the angle of view 10 of the lens of the camera 2 as well as the field of view 11 of the field of view. In FIG. 4 shows the “calibrated periodontal probe” tip, the focus of camera 2 is set to the working part of the tip. When installing any other nozzle, its working part is also in focus. For example, in FIG. 7 the focus of the camera is set to the head of the handpiece with the “ball-shaped bur” installed - its working part is also in focus.

The control device 3 transmits a control signal to the processing device 4 and can be made in the form of a foot switch (see Fig. 2).

The processing device 4 provides video signal processing, processing of signals from sensors, recording information on internal memory cards, as well as outputting HDMI + SDI video signal to the video signal display device 5. The processing device 4 controls the broadcast and recording of cameras using position sensors in space, acceleration and sensor signal processing module.

The video signal display device 5 may be a monitor 5.1 and/or a projector 5.2 in a lecture hall (see FIG. 2).

The operation of an imaging system for medical purposes is shown using a general camera 1 and two miniature cameras 2 as an example.

Miniature chambers 2 are fixed to the instruments/handpieces. The doctor works with instruments in turn. Thus, one camera 2 is actively moving in space, while the second camera 2 is lying down. The processing device 4 reads the signals from the sensors of both cameras 2, recognizing which one is in the doctor's hands and automatically switches the broadcast and recording to the "active" camera 2. If both miniature cameras 2 are lying, then the control device 3 connects the general camera 1 to the broadcast .

Thus, the doctor or other personnel do not need to be distracted and monitor the switching of the broadcast to the classroom, stop the recording of the camera of an inactive instrument, switch the recording, etc.

All this allows the doctor to work more involved, not to involve additional personnel in the operating room, to produce broadcasts of higher quality, to receive more detailed records of manipulations.

When using two miniature cameras 2 in the visualization system, fixed in such a way that the recorded/broadcast video forms a stereo pair, the specified video can be used to create 3D video.

Implementation examples

The imaging system was used to film and record various dental procedures (see photo in Figs. 10-12). In FIG. 10 shows a graduated probe pointing to the central fissure of tooth 37. All objects of interest are in focus, which allowed the doctor to show close-ups of the smallest nuances of the work during the demonstration session, without being distracted by the technical component.

Features of the claimed imaging system

Due to the small size of the camera and the above-described mounting system, a number of advantages have been obtained when shooting medical procedures:

- no additional staff is required in the operating room to control and set up the video recording process;

- the doctor is not distracted from the operation;

- a unique shooting angle is provided, the working part of the tool is always in the center of the frame;

- there are no such interferences as gloves, etc. on the final record;

- a wide area of use for various medical manipulations due to the use of an articulation hinge for intermediate mounting of a miniature camera;

- quick change of tools, due to the use of additional devices: a universal handle and a fixing ring;

- The combination of the articulation joint and interchangeable tips ensures that the head of the working tip is always in focus when changing the tip.

Thus, the use of the claimed system provides an increase in the quality of translation and recording of medical manipulations, expanding the scope for various types of medical manipulations; simplification of the process of shooting and visualization; speeding up and simplifying the change of tools and changing the shooting angle, as well as a significant reduction in the influence of the human factor on the control and adjustment of the video shooting process.
