Definitions

  • the invention relates to a device for examining a human breast with at least one diagnostic examination device, with which image information can be obtained from inside the body of a living being, two compression devices that can be adjusted relative to one another, which include spaces for accommodating the breast and the tissue area near the chest wall, and a patient support is oriented at least substantially horizontally.
  • Such a device in the form of an X-ray device is known for example from US 5,078,142 and is used both for diagnostics and for interventions, i. H. for minimally invasive procedures under X-ray control, used on a patient's breast.
  • the patient lies with her stomach on a patient support, among other things.
  • the ascent to the patient support is facilitated in the present case in that the patient support has a pivotable about a horizontal axis, i. H. has a foldable foot section which, after the patient has assumed a bent position on the X-ray device, is moved horizontally.
  • the stooped posture is only used for better ascent and descent of the patient and not for examination.
  • the patient is positioned on the patient support in such a way that the patient's breast to be examined or undergoes an intervention hangs through a circular opening in the patient support in the space enclosed between two compression devices. Before the examination or hit event, the breast is compressed between the compression devices.
  • an X-ray beam emanating from an X-ray source penetrates both the compression devices and the breast and strikes an X-ray receiver, e.g. B. an X-ray film, which is then evaluated for image acquisition.
  • a disadvantage of the known X-ray device is that the tissue areas of the breast to be examined near the chest wall cannot be radiologically imaged due to the retention effect of the patient support of tissue around the circular opening and are not accessible for intervention due to their position in the opening of the patient support.
  • tissue areas of the breast to be examined near the chest wall cannot be radiologically imaged due to the retention effect of the patient support of tissue around the circular opening and are not accessible for intervention due to their position in the opening of the patient support.
  • mammography images such as the medio-lateral oblique recording
  • parts of the arm adjacent to the breast to be examined and the upper abdomen are compressed together with the breast for a maximum display of the tissue, which is not possible due to the circular opening of the patient support which is adapted to the shape of the breast.
  • the tissue area near the chest wall which cannot be imaged or accessed radiologically, has at least a thickness which corresponds to the thickness of the patient support.
  • the published patent application DE 26 33 828 AI describes a method and a device for X-ray mammography.
  • the patient's chest, shoulder and head are supported on a horizontal table.
  • the chest extends down through an opening in the table into a liquid-filled container.
  • the disadvantage of the two inventions is that the contact surface projects beyond the rear edge of the compression plates towards the patient and thus prevents parts of the breast near the chest wall from being imaged. So it is not possible to bring parts of the armpit and upper abdomen into the compression area so that they are far below the rear edge of the compression plates. A complete examination of the breast is not possible with the solutions described.
  • the invention is therefore based on the object of designing a device of the type mentioned in the introduction in such a way that a complete examination of the human breast is possible.
  • the object is achieved by a device for examining a human breast of patients (female patients / male patients) with at least one diagnostic examination device, with which image information can be obtained from the inside of a living being, two compression devices which can be adjusted relative to one another and which have a space for receiving the Include chest (compression area) and means for positioning the patient in a lying position or in the upper body bent examination position, which comprise a patient support supporting at least the stomach of a patient and provided with at least one support surface.
  • This support is oriented at least substantially horizontally, the patient support neither completely nor partially covering the space between and next to the compression devices necessary for the complete examination of the breast.
  • the breast to be examined can hang freely between the compression devices when the patient is lying on the device with the upper body at least bent, so that no tissue, in particular no tissue close to the chest wall, is retained in any way by the patient support. In this way, when the breast is compressed due to the influence of gravity, the tissue close to the chest wall is also detected and accessible for examination or intervention.
  • the device according to the invention not only offers the advantage that more tissue is detected during an examination, but that the examination is also less painful for the patient, because in contrast to a standing examination position due to the influence of gravity, the breast is not pulled into the breast by strong manual pull Space must be placed between the compression devices.
  • the means for positioning preferably include various positioning elements so that a patient can assume various examination positions on the device, namely a standing examination position bent over the upper body, a kneeling position bent over the body or a lying position.
  • the diagnostic examination device comprises an X-ray device and / or a diagnostic ultrasound unit.
  • the ultrasound unit has an ultrasound applicator suitable for diagnostic purposes and the x-ray device has an x-ray system suitable for mammography, comprising an x-ray source and an x-ray receiver, an x-ray beam emanating from the x-ray source during operation to the x-ray receiver, the edge beam of which is at least essentially horizontal on the patient side, so that only the tissue areas of the breast to be examined are penetrated by the X-ray beam.
  • the device according to the invention can thus have a diagnostic ultrasound unit, an X-ray device or both as a diagnostic examination device, in the latter case breast tissue can alternatively be examined with one and the same device using ultrasound or X-ray radiation.
  • a breast-receiving medium is provided between the compression devices, which medium has essentially the same sound impedance as body tissue, so that the diagnostic ultrasound can spread into the breast tissue practically unhindered.
  • a preferred embodiment of the invention provides that the means for positioning comprise an angled bearing element for positioning the abdomen and / or the hip region of a patient taking an examination posture bent over the upper body.
  • the Bent examination posture of a patient offers the advantage that the patient can be positioned more easily and quickly on the patient support or the patient's breast to be examined between the compression devices, since the patient's arms and upper body can be moved freely.
  • the device can be left more quickly, which increases the patient throughput and thus the efficiency of the device.
  • Another advantage of this embodiment of the invention lies in the fact that during an examination or an intervention on a patient in a bent examination position, due to the low position of the legs compared to the head of the patient, there is no relevant redistribution of blood volumes in the patient's body.
  • An angled bearing element is understood to mean a bearing element which has a curved surface which is adapted to the body shape in the hip region of a person bent over the upper body.
  • An embodiment of an angled bearing element may have an at least substantially horizontally oriented surface which is connected to an at least substantially vertically oriented surface of the bearing element, preferably by a curved surface.
  • the angled bearing element is at least superficially made of an elastic material and preferably has an internally arranged shield that is opaque to X-rays.
  • the superficially elastic material is advantageous for comfortable positioning of a patient and is preferably disinfectable.
  • the shield protects a patient's genitals from X-rays in the bent examination position when the chest is examined with X-rays.
  • the means for positioning comprise a height-adjustable foot step on which the patient can stand during an examination.
  • the kick enables a patient in the examination posture to intercept his body weight to a certain extent by contact with a tread surface, which is why components of the means for storage in some areas do not have to be as stable as in conventional patients.
  • the height adjustment of the foot pedal also makes it possible to compensate for different patient leg lengths, so that patients of different sizes can each take a comfortable examination posture on the device.
  • the foot step has an arcuately curved area.
  • a patient can adopt a posture that is propped against the arched area of the footstep with one or both feet, so that the footstep is prevented from slipping off when the examination posture is bent.
  • the embodiment of the foot kick with an arcuately curved region enables the angle in the hip joint of a patient to be greater than 90 ° when the examination posture is bent, which can prove to be particularly advantageous when the joint is restricted in movement.
  • the angled bearing element and / or the foot step are arranged on a device part which is adjustable relative to the diagnostic examination device.
  • a variant of the invention provides that the device part has a shield that is impervious to X-rays, so that the genitals of a patient in a bent examination position on the device are protected from X-rays when the breast is examined with X-rays.
  • the device part can be fixed relative to the diagnostic examination device, so that an undesired adjustment of the device part, for example due to impact, can be prevented for a patient from an examination setting once found.

  • the length of the patient support can also be variably adjusted to the space between the one compression device closest to the patient support and be adapted to the angled bearing element for comfortable positioning of the patient.
  • the support elements are, by means of an adjustment mechanism, in a storage area inside the angled bearing element retractable and extendable. In this way, support elements that are not required can be intermediately stored without problems and, if necessary, used to position a patient.

  • the telescopic rods also have a supporting effect in that they absorb part of the body weight of a patient lying on the patient support.
  • the patient support can be fixed in a certain position.
  • a separately arranged or a corresponding trigger mechanism on the device interacts with suitable means for fixing the telescopic rods, so that the length of the patient support can only be changed after the trigger mechanism has been actuated. In this way, an unwanted change in the length of the patient support from a setting found for a patient is prevented.

H. are pivotable or rotatable, the compression devices can be adjusted synchronously with the diagnostic examination device.
  • the adjustment of the diagnostic examination device together with the compression devices around an axis offers the possibility of taking diagnostic images of a breast from different directions.
  • Variants of the invention provide that differently shaped support elements can be inserted in the space created between the patient support and the compression device arranged closest to the patient support due to relative movements between the patient support and the compression devices coupled to the diagnostic examination device, or a deformable bellows-like arrangement in the space Support element is provided which is at least indirectly connected to the compression device and the patient support.
