Ground support for medical imaging module and medical imaging module

Technical Field

The utility model relates to a be used for medical science imaging module

Configured to perform a pivoting movement of the medical imaging unit, and a medical imaging module comprising the ground support.

Background

In medical technology, ground stands or supports are provided in imaging modules for a variety of applications, which can perform a pivoting movement relative to a patient about a pivot axis, for example a vertical axis. The floor stand is typically connected to the base via standing feet. The base may in particular be the floor of an examination room.

This arrangement is especially found in angiographic systems, such as C-arms. In particular, in this embodiment, the medical imaging module is a C-arm. Here, the C-shaped holding device is arranged on a floor bracket, which typically can pivot the holding device about a vertical axis, i.e. a pivot axis. It is particularly typical for the pivot axis to be arranged centrally on or above the standing foot. Typically, the medical imaging unit comprises at least one radiation source or X-ray tube and/or a radiation detector or X-ray detector, which is arranged on the holding device or on the ground support.

Typically, the pivot axis is disposed in the axis with the central ray of the source. The central ray is an X-ray emitted by the radiation source perpendicularly out of an exit window of the radiation source. The standing foot is therefore also arranged in the axis of the central ray. The standing foot comprises a rolling bearing in order to enable pivoting of the holding device about the pivot axis. Typically, a patient is positioned on an examination table for examination by means of a medical imaging module. The examination table is typically positioned during the examination into a position in which a portion of the examination table is disposed in the central ray above the standing foot. In other words, the pivot axis intersects the couch at a point. Typically, the pivot axis intersects the couch at a right angle in an initial position of the couch. In the initial position, the examination table is arranged horizontally. In embodiments, the examination table may be tilted such that the pivot axis and the examination table do not intersect at a right angle.

Typically, the standing foot is configured with a circular base surface. In particular, the diameter of the round standing foot is typically larger than the width of the examination table. In the embodiment described, the standing foot interferes with the doctor or medical staff, since the standing foot is typically designed such that the doctor's foot must be positioned at a distance from the patient on account of the standing foot. In other words, standing the foot in embodiments limits the standing area of the physician. The standing area here includes the position of the doctor, which the doctor must occupy with respect to the patient during the examination.

In an alternative embodiment, the standing foot is disposed outside of the standing area and the central ray. This embodiment requires a large mechanical effort and is very complex with regard to installation and material costs. Standing feet outside the standing area require one or more hinges in the standing foot. The bearing of the pivot point of such a joint is realized by means of a rolling bearing. The rolling bearing is designed such that pivoting of the medical imaging device can be performed and such that tilting moments due to the holding device are compensated. In particular, in said embodiment, the leverage effect caused by the holding device must be balanced.

SUMMERY OF THE UTILITY MODEL

The invention is therefore based on the object of providing a floor stand which limits the standing area of the doctor and provides a cost-effective and mechanically simple solution for centering the standing foot relative to the central ray.

The purpose is through realizing according to the utility model discloses a ground support. The object is also achieved by a medical imaging module according to the invention. Preferred and/or alternative, advantageous embodiments are the subject matter below.

A first aspect of the present invention relates to a ground support for a medical imaging module, comprising a standing foot and a pivoting element. The standing foot is anchored in the base. The pivot element is here connected pivotably about a pivot axis to the standing foot. At least one medical imaging device is arranged on the pivot element, which medical imaging device can be positioned by means of a pivoting movement of the pivot element. The standing foot comprises a recess, which is embodied in the form of an arch or in the form of a sector.

In particular, the circular segment is a circular surface or a circular partial surface. The sector is bounded by two radii and a circular arc. Radius or circle radius is the linear connection between the center or midpoint of a circle and the circumference. In particular, the fan shape may be characterized by an angle. The angle describes the angle of the radii relative to each other. In particular, the angle thereby describes the size of the sector. The circular arc describes the connection between two intersection points of two radii and the circumference. The arc extends along a circumference.

In particular, the base surface and the recess of the standing foot are complementary. In other words, the base surface of the standing foot and the recess jointly form a circular surface. In particular, in the embodiment, the sectors of the base surface and the recesses are formed complementary to one another. In particular, the angle characterizing the recess is thereby also greater than 0 ° and less than 360 °. In particular, the angle of the recess comprises 360 ° minus the angle of the base surface. In particular, the transition between the base surface of the standing foot and the recess can be rounded.

In particular, the standing foot is anchored in the base. The base can be, for example, the floor of an examination room. The anchoring may be, for example, concreting or fixing in the ground by means of bolts or screws. In particular, the standing foot is therefore not movably formed relative to the base.

In an alternative embodiment, the standing foot can be arranged on the at least one guide element. In particular, the at least one guide element is then formed immovably relative to the base. In particular, the standing foot can then be moved along at least one guide element. In particular, the standing foot can be moved along the at least one guide element in one dimension. In particular, the at least one guide element may be designed as a rail.

In particular, the pivoting element can pivot or rotate about a pivot axis relative to the standing foot. In other words, the pivoting element may perform a pivoting or deflecting movement about the pivot axis. In particular, the pivot axis may be arranged perpendicular to the base. In particular, then, the pivoting movement of the pivoting element is performed in a plane parallel to the base. In an advantageous embodiment, the pivot axis can extend through the center of the circular standing foot. In other words, the pivot axis may be referred to as a rotation axis or a turning axis.

In particular, the medical imaging module may be an X-ray radiation based imaging module. In particular, the medical imaging module may be, for example, a C-arm X-ray module. Alternatively, the medical imaging module may be a conventional X-ray module.

In particular, the medical imaging unit arranged on the pivot element may comprise a radiation detector or an X-ray detector. Alternatively or additionally, the medical imaging unit arranged on the pivot element may comprise a radiation or X-ray source or X-ray tube. The radiation detector and/or the radiation source can be arranged directly on the pivoting element. Alternatively, the radiation detector and/or the radiation source can be arranged on a holding device, which is in turn arranged on the pivoting element.

In an advantageous embodiment, the medical imaging unit comprises a radiation source and a radiation detector, which are arranged opposite to each other. For this purpose, the medical imaging unit can furthermore comprise a C-shaped holding device or holder for the radiation detector and the radiation source. The C-shaped holding device is arranged on the pivoting element and can be pivoted relative to the standing foot by means of the pivoting element. The radiation detector and the radiation source are arranged opposite one another on the ends of the C-shaped holder. In particular, the radiation detector and the radiation source are arranged such that the central ray of the radiation or X-ray radiation extends along the pivot axis from the radiation source towards the detector.

In a preferred embodiment variant, the radiation detector is a flat panel detector or an X-ray flat panel detector. Here, it may be a semiconductor detector or a scintillation detector. In a preferred embodiment, the radiation detector is a digital X-ray detector.

The source of radiation is advantageously a rotating anode X-ray tube. Alternatively, the radiation source may also be a transmission anode X-ray tube. The radiation source comprises an exit window from which the X-ray radiation advantageously emerges as cone-shaped radiation.

In an alternative embodiment, the medical imaging unit comprises, for example, a work light, which can be positioned by means of a pivoting movement. In particular, the work light may be positioned such that it illuminates the work area of the doctor or of the medical staff. The working area may be, for example, an examination area or a surgical area.

In a preferred embodiment, the examination table or the patient on the examination table may be positioned such that at least a part of the patient is positioned in the pivot axis. In particular, then a portion of the patient is positioned over the standing foot. This is advantageous in particular when the central beam of X-ray radiation extends along the pivot axis. In this way, the central beam can be used for imaging or X-ray imaging.

The inventors have realized that a clearance in the standing foot can be achieved without the doctor or medical personnel being hampered or restricted by the standing foot. In particular, the doctor or medical staff can have unrestricted access to the patient within the clearance, who is positioned above the standing foot on the examination table. In particular, the risk of a doctor or medical personnel tripping over a standing foot can be minimized.

Furthermore, the inventors have realized that an operating unit, for example comprising a foot switch, may be provided in the hollow. The foot switch can be designed, for example, for controlling the pivoting movement and/or for triggering or switching on the X-ray radiation. Advantageously, the doctor or medical staff then frees both hands for the treatment of the patient. In particular, the foot switch in the recess is easily accessible to the doctor or medical staff.

In one embodiment, the segment or segment of the recess covers an angle of at least 90 °.

In particular, the angle characterizing the clearance may cover exactly 90 °, 100 °, 110 °, 120 °, 130 °, 140 °, 150 °, 160 °, 170 °, or 180 °.

The inventors have realized that a large angle of the base surface characterizing the standing foot is advantageous for the stability of the medical imaging module. A large angle characterizing the base plane of the standing foot may be, for example, an angle between 270 ° and 240 °. In particular, the angle characterizing the clearance is then between 90 ° and 120 °. Alternatively, the inventors have recognized that a small angle characterizing the base plane of the standing foot allows a doctor or medical person more freedom in the foot area, or less encumbered or unhindered. In particular, in the case where the angle characterizing the base surface of the standing foot is small, the angle characterizing the vacant part is large. Thereby, the space is also large. The small angle characterizing the base plane may be, for example, an angle between 180 ° and 240 °. In particular, the angle characterizing the clearance is then between 180 ° and 120 °.

In one embodiment, the segment or segment of the recess covers an angle of 120 °.

In other words, the clearance encloses an angle of 120 °. In other words, the angle characterizing the clearance comprises 120 °. In particular, then the angle characterizing the base plane comprises 240 °. In other words, then the base surface encloses an angle of 240 °.

The inventors have realized that an angle of 120 ° enclosed by the clearance provides an advantageous compromise between stability of the medical imaging module and freedom for the doctor or medical personnel in the standing area.

In one embodiment, the pivot element is pivotably connected to the standing foot via a bearing, wherein the bearing is arranged outside the recess along the circumference of the standing foot.

In particular, the pivot axis of the pivoting movement extends vertically centrally through the standing foot. In particular, with the arrangement described, it is possible to provide standing feet which do not comprise the entire circular surface as a base surface. In other words, the arrangement described enables a recess of the standing foot, while nevertheless a pivoting of the pivoting element about the standing foot is possible. This allows space for a doctor or medical staff in the foot region. In particular, the doctor or medical staff can approach the patient at will on an examination table which is positioned above the standing foot and at the same time the position of the medical imaging unit is adjusted by means of a pivoting movement along the bearing.

In particular, for said purpose, the surface of the first guide rail may be roughened. In particular, when the first guide rail is composed of hardened steel, the first rolling elements can likewise be composed of steel or hardened steel without increasing the wear of the first guide rail.

The inventors have realized that it is advantageous to match the material of the first guide rail to the wear and in particular to the material of the first rolling element. In particular, the inventors have realized that it may be advantageous for the first guide rail to be constructed as a separate component. Advantageously, the standing foot can then be made of a more cost-effective and/or lighter material than the first guide rail. This may result in cost savings in manufacturing the floor stand.

Advantageously, the force of gravity is distributed over a plurality of rolling elements in the case of more than one rolling element. The inventors have realized that wear of the individual rolling elements can thereby be reduced. In particular, when more than one rolling element rolls on the first guide rail, the individual rolling element can be constructed with less stability and thus more cost-effectively, since instead of on the individual rolling element, the gravitational load is on a plurality of rolling elements.

In one embodiment, the travel element comprises at least one second rolling element, wherein the guide element comprises at least one second guide track, wherein the at least one second rolling element rolls on the second guide track.
