Definitions
- the present disclosure relates to the lighting concept of a camera arrangement for medical devices, e.g. surgical instruments.
- the camera arrangement detects at least machine-readable codes that are attached to medical devices, e.g. surgical instruments.
- surgical instruments are recorded individually, e.g. to compile a selection of several instruments and make them available to the operator or surgeon. This recording can be done semi-automatically by manually sorting the instruments while electronic monitoring takes place using a camera system that serves as a scanner.
- direct lighting units are known to make the respective machine-readable code of the surgical instruments visible to the camera.
- the IOSS document DMT100 discloses a camera arrangement designed as a table-top device with a camera eye on the top.
- a user of the machine-readable two-dimensional data matrix code holds of the surgical instrument via the camera eye, which is then automatically read in.
- Multi-channel LED lighting is provided, whereby the appropriate channel is automatically selected from four lighting channels.
- a fundamentally similar tabletop device for scanning data matrix codes, even from curved surfaces of the surgical instruments concerned, is known under the product name Surgiscan or Surgiscan Ultra from 2DSurgical.
- the camera arrangement has an indirect lighting unit.
- the corresponding data sheet of the same name discloses LED lighting with 256 colors for constant lighting or for flash operation.
- the object of the present disclosure is to provide a camera arrangement at least for scanning machine-readable codes, the recognition reliability and speed of which are improved compared to the prior art.
- the camera arrangement for or for the detection/visual handling/assessment or for use in handling medical devices, e.g. surgical instruments has a first camera which is set up and designed at least for detecting machine-readable codes of medical devices, e.g. surgical instruments.
- the camera arrangement has a first direct lighting strand with a plurality of LEDs (i.e. a number of LEDs are arranged on a first direct circular path, preferably around the first camera as the center), the light of which is preferably directed directly onto a reading area or work area for the medical device or its code by an at least partially circumferential, preferably ring-shaped diffuser.
- the camera arrangement also has a first indirect lighting strand with a plurality of LEDs (i.e.
- a number of LEDs are arranged on a first indirect circular path, preferably around the first camera as the center), the light of which indirectly via a first, e.g. concave reflection dome onto the reading area.
- the first (single or multi-piece) reflection dome is arranged on a side of the first two lighting strands facing away from the reading area.
- medical device includes, for example, the surgical instruments already mentioned or other medical instruments or medical devices or parts of medical devices or medical products or medical consumables.
- the reflection dome can also be made up of several parts, e.g. composed of several surfaces.
- a hollow cuboid is also possible in terms of device technology.
- individual sections of the lighting strands can preferably be controlled separately and adjusted to the conditions in terms of brightness in order to achieve ideal lighting for the reading process (homogeneous illumination of the code / minimization of reflection / maximization of the contrast between the medical device and the code).
- a further development stage is the combination of adaptive lighting as described above and a camera with autofocus (e.g. voice coil motor or liquid lens).
- autofocus e.g. voice coil motor or liquid lens.
- a simple development in terms of device technology with optimal lighting is also provided if at least one of the two first lighting strands is arranged and/or attached to a circumferential inner edge of the first reflection dome.
- the first (e.g. ring-shaped) diffuser is also arranged and/or attached directly or indirectly to the circumferential inner edge of the first reflection dome.
- a control software or a control unit is programmed in such a way that a camera image can be generated, for which purpose the first two lighting strands can be controlled alternately one after the other.
- an exposure time of the first camera of 2 ms and a frequency of control of the two lighting strands of 500 Hz are provided.
- the autofocus is carried out, for example, by means of a voice coil motor or liquid lens.
- control software or the control unit is programmed in such a way that at least two (preferably several) images of the first camera can be generated one after the other, whereby each individual camera image can be generated by controlling only one of the two first lighting strands.
- the optimal camera image, which is generated by means of the optimal first lighting string was generated by comparing at least two (preferably several) camera images.
- the medical devices can be handled advantageously if the first two lighting strands are arranged approximately horizontally and if the first reflection dome is arranged above the first two lighting strands, while the reading area is arranged below the first two lighting strands. This means that the light rays of the LEDs of the first direct lighting strand (at least with one component) are directed downwards, while the light rays of the LEDs of the first indirect lighting strand (at least with one component) are directed upwards into the first reflection dome.
- the first camera is arranged in a recess of the first reflection dome.
- a second camera (ie preferably opposite to the first camera) is arranged on a side of the reading area facing away from the two first lighting strands and the first reflection dome and the first camera, wherein the camera arrangement further comprises a second direct lighting strand with several LEDs, the light of which is directed directly onto the reading area through an at least partially circumferential (e.g. ring-shaped) diffuser.
- the camera arrangement also has a second indirect lighting strand with several LEDs, the light of which is directed indirectly onto the reading area via a second, e.g. concave, reflection dome.
- the second reflection dome is arranged on a side of the two second lighting strands facing away from the reading area.
- the supplementary lighting can be in the visible or non-visible wavelength range or can change its wavelength within different lighting scenarios.
- the two cameras are then designed for different wavelength ranges from the group of visible light, UV light and IR light.
- Glare must be prevented, particularly when the two cameras are directed at each other (shared optical axis).
- Bandpass filters are preferably used for this purpose.
- a camera arrangement with a parabolic mirror is also conceivable. This will be one of the first two lighting strands and the side of the reading area facing away from the first reflection dome in order to optically enlarge the machine-readable code through its specific curvature. The distortion that arises as a result can be calculated from the image.
- the parabolic mirror is concave, with the first camera being arranged in a focus of the parabolic mirror. If further lighting is arranged, for example, adjacent to the focus of the concave parabolic mirror, the light of which is directed indirectly via the parabolic mirror onto the reading area, a further improved illumination or a further alternative lighting scenario of the reading area or work area is provided.
- the codes that can be machine-read by the camera system are, in particular, two-dimensional area codes or barcodes, particularly data matrix codes, but also one-dimensional codes such as conventional barcodes.
- OCR character recognition
- the camera arrangement in particular its electronic evaluation unit, further adapted lighting scenarios are possible for other applications, for example for the inspection of surfaces or the inspection of cutting edges.
- the previously mentioned reading area of the machine-readable code is also an inspection area of the instrument.
- Additional illumination in the UV range is useful, for example, to better detect contamination of the instrument.
- the lower lighting strand is called the direct lighting strand 8, since its LEDs, which are preferably evenly distributed around the circumference, emit their light through a surrounding, e.g. ring-shaped diffuser 9 downwards directly to the medical device, e.g. instrument, or to its machine-readable code.
- the diffuser 9 in front of the direct lighting strand 8 produces a greater light scattering. This type of lighting produces dark field lighting.
- the upper lighting strand is called indirect lighting strand 6 because its LEDs, which are evenly distributed around the circumference, emit their light upwards into the reflection dome 4 and thus indirectly illuminate the medical device or its machine-readable code.
- the two lighting strands 6, 8 are controlled offset at a frequency of 500 Hz. During a control, only one of the two lighting strands 6, 8 is active. This creates different lighting scenarios, which highlight different artifacts on different surfaces of the medical device, e.g. instruments.
- the timing of the lighting strands 6, 8 is not visible to the user. The timing can be perceived via the camera image. To compensate for this, the exposure time of the sensor or camera 1 is set to 2 ms.
