Description

[Technical Field]

[0001] The present invention relates to a holding device for radiological examination, particularly for a radiological examination device, and a radiological diagnostic system having the holding device for radiological examination and a radiological diagnostic device such as a CT (Computer Tomograph), an MRT (Magnetic Resonance Tomograph), an X-ray device, or a radiotherapy device. [Background technology]

[0002] A computed tomography or magnetic resonance imaging device tends to include a tube of some kind through which a patient passes to obtain the necessary images. Hereinafter, magnetic resonance imaging or computed tomography or x-ray devices will be generally referred to as x-ray devices.

[0003] When performing X-rays, MRI, or CT scans on bedridden patients, the patient must be carried into the room where the X-ray equipment is located while still in a bed or wheelchair and positioned next to a stretcher or treatment table. Then, before the MRI or CT scan can be performed, the patient must be transferred from the bed, wheelchair, or stretcher to the treatment table. This movement and correct positioning requires a great deal of force and time.

[0004] Patent Documents 1 and 2 disclose a holding device for radiological examinations that supports and assists these movements. A rotatable support arm includes a holding grip for the patient to hold on to. The support arm is rotatable, and its angle can be fixed. When a cable to which a grip ball is attached is pulled, the bolt is released from the hole circle, releasing the support arm and allowing it to rotate. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] German Patent Publication DE 20 2016 106 093 U1 [Patent Document 2] German Patent Publication DE 10 2019 119 025 A1 Summary of the Invention [Problem to be solved by the invention]

[0006] In Patent Document 2, the pull rope is guided horizontally radially outward along the support arm by a guide sleeve, allowing it to be actuated radially outward as well as toward the center. This is advantageous and simplifies operation. However, its drawback is rope slack. The rope must be tightened before the bolt is released to rotate the support arm. At the point where the rope is pulled, it may be pulled (backward) from the guide without moving the release bolt. The operating distance that the slack rope must cover to release the bolt depends on the location where the pulling force is applied. Furthermore, pulling the slack rope may change the position of an adjacent knob connected to a position away from the pivot of the support arm, causing the knob to move out of reach. The pulling travel distance to release the bolt is undefined and unpredictable for the user, especially when operating multiple times. Therefore, there is a risk that the bolt release will be unpredictable when the person moves.

[0007] It is therefore an object of the present invention to provide a holding device for radiological examination that facilitates operation of the holding device for radiological examination, preferably enabling reliable operation, and particularly improving hygiene. [Means for solving the problem]

[0008] This object is solved by a holding device for radiological examination having the features of claim 1 and by a radiological examination system having the features of claim 22. Preferred specific embodiments of the invention are the subject of the subclaims. Further advantages and features of the invention can be gleaned from the general description and the description of exemplary embodiments.

[0009] The holding device for radiological examinations according to the present invention is particularly provided for at least one radiological examination device, preferably at least one X-ray device, MRT device, CT device, or radiotherapy device, or similar or equivalent devices. The holding device for radiological examinations comprises a mounting device and at least one support arm rotatably accommodated thereon. The support arm comprises at least one shaft and at least one support part. The shafts of the one or more support arms are rotatably supported on the mounting device. The holding device for radiological examinations comprises at least one locking device for locking the support arm in at least one of the rotation positions corresponding to each of a plurality of angular positions. The angular positions to which the support arm can be locked are the locked positions.

[0010] At least one actuation mechanism is provided for actuating, in particular unlocking and / or locking, the locking device, the actuation mechanism comprising at least one transmission element and at least two actuation elements, the transmission element being configured at least in part as a flexible tension member.

[0011] At least one holding device is provided for attachment of the support arm, e.g., for holding a patient. Thus, the patient can grasp the holding device, e.g., to assist in lifting, moving, repositioning, or transporting themselves. This particularly allows the support arm to be easily rotated to place it in different operating positions. The actuation mechanism has at least one force-directing unit for controlling the operating force, directed toward the locking device, introduced into the flexible pull element (between its ends) to actuate the locking element. The force-directing unit prevents the transmission of force in one direction (by the flexible pull element). In particular, the transmission of force in the radially inward direction is prevented. Preferably, the mobility of the pull element can be blocked radially inward.

[0012] The force directing unit may be configured as a blocking unit to block the transmission of force in one direction.

[0013] The flexible pull element is particularly (at least partially) configured as a rope-like member. The flexible pull element may in particular be configured as or consist of at least one of a rope, a band, a cord, a flexible wire, etc. Preferably, the flexible pull element is at least partially configured elastically. The flexible pull element may also be provided to plastically deform within a certain range. Preferably, the flexible pull element is at least partially configured from nylon or another synthetic material, in particular nylon fibers, metal, in particular metal, synthetic fibers, strands, or even natural fibers such as cotton, hemp, etc. The flexible pull element is particularly configured as a pull rope, band, thread, rubber band, and / or chain.

[0014] The transmission component may be made up of a plurality of elements, at least one of which may be configured as or include a rigid rod.

[0015] The holding device for radiological examinations according to the invention has many advantages: the force induction unit transmits the operating force introduced (in the flexible pull member) for actuating the locking device directly to the locking device and makes it possible (among other things) to utilize the introduced operating force for actuating the locking device; the risk that the locking device will become inoperable or will only be operable with a very long and / or indefinite actuating stroke, especially when moving the patient, is minimized or completely eliminated.

[0016] The force-guiding unit is particularly advantageous in that it allows for the introduction of an operating force at any desired position along the transmission part, in particular the flexible pull member, respectively, for controlled actuation of the locking device. The force is bent and / or directed in the desired direction by the force-guiding unit (respectively the blocking unit). The flexible pull member, configured as a rope, cannot be pulled out of the guideway. The flexible pull member is prevented from exhibiting unintentional slack. This results in a substantially defined operating range.

[0017] The transmission element of each flexible pull element is positioned horizontally at a large distance from the locking device, particularly at a distance greater than the user's arm's length, so that even when the flexible pull element is configured as a long horizontal guide, particularly given a significant distance from the axis of rotation, the proportion of the introduced pulling force or actuation travel that does not contribute to the actuation of the locking mechanism is minimized.

[0018] In the case of slack flexible pull elements, or multiple flexible pull elements and / or actuation elements, a defined actuation range is established (independent of the actuation position along the flexible pull elements), and in any case, it is not necessary to (initialize) tighten the slack range radially behind the actuation point (respectively further from the pivot point) before applying the actuation force.

[0019] The force-directing unit (respectively the blocking unit) causes at least one local locking of movement in (at least) one direction, which prevents inward movement of a section of the flexible pull member if the actuation point is located radially inward of the force-directing unit. As a result, when the locking device is actuated, the actuation is direct and there is no need to tighten an elongated, e.g. slack, section of the flexible pull member and move it from radially outward to radially inward before the locking device actually acts. This increases reliability and safety during operation.

[0020] The handling of the holding device for radiological examinations as a whole, and in particular of the support arm, is improved. The reliability of the actuation mechanism is significantly increased.

[0021] The fixed position of the transmission and flexible pull elements protects them from excessive contamination. The actuating elements are advantageously always gripped in the same place. This aids and promotes hygiene, particularly of the holding device for radiological examinations. Furthermore, the actuating mechanism is primarily easy to operate, which facilitates ease of use.

[0022] At least one force directing unit (configured as a blocking unit) is configured. The force directing unit directly transmits the operating force applied to the locking device to operate it, making it possible to (almost) fully utilize the operating force and operating range to operate the locking device. The force directing unit transmits the operating force applied to the operating member in a preferred direction. That is, the transmission part moves in the preferred (opposite) direction. When multiple operating parts are arranged in series at different positions and one intermediate (between both ends) operating part is operated, the force directing unit guides the force substantially only in one direction. The movement of the transmission part is (substantially) in one direction. Movement in the opposite direction is (almost) blocked. As a result, the force directing unit clearly directs the force and direction of movement applied to operate the locking device and effectively controls it in the desired direction, thereby reducing the required operating movement.

[0023] In its intended, proper, normally configured and usable state, the axis of rotation of the support arm is oriented at least substantially vertical, or substantially nearly vertical, or (almost or exactly) vertical or horizontal. The mounting device is preferably configured as a mounting console, particularly mounted on the ceiling of, for example, a radiology room. The mounting device may also be configured as a wall mount, particularly supported on, for example, a substantially vertical room wall.

[0024] The holder is in particular a holding grip or includes a holding grip. The holder (holding grip) is in particular height-adjustable and can therefore be adapted to short or tall people. Preferably, the holder or at least one holding grip is height-adjustable by at least 100 mm, in particular 200 mm or 300 mm, or even 500 mm or 1 m or more.

[0025] Preferably, the support parts are each arranged with their bottom surface at a height of about 2000 mm or 2250 mm or more from the ground. Particularly adjustable holders may be arranged at a height of 2000 mm or more. The higher the height, the more headroom there is.

[0026] The mounting device can also be arranged directly on the radiological inspection apparatus and / or can in particular be formed integrally with and / or attached to the radiological inspection apparatus. In this and other cases, the orientation of the rotation axis of the support arm can be adjustable by means of an adapter. Alternatively, the actuation device can be mounted on a wall or floor or otherwise positioned on the ground, respectively, on the floor.

[0027] The support arm is arranged and / or housed, preferably fixed, in particular at least rotatably, in a mounting device of the holding device for radiological examinations. The transmission part, when the actuation mechanism is activated, moves substantially axially along or closely adjacent to the axis of rotation, in particular at least partially. Preferably, the transmission part moves at least partially in a central direction through the axis of the support arm.

[0028] The transmission element is preferably made of a non-magnetic and / or electrically non-conductive material, so as to avoid antenna effects due to the transmission element, in particular in the area passing through the shaft, the area passing through the shield, the adjacent area or the area in the immediate vicinity.

[0029] The shank and / or support part are preferably configured as (circumferentially closed) tubular parts along the longitudinal axis, at least partially or in sections, exhibiting a circular, elliptical, and / or square cross section in cross section. The tubular parts may exhibit a circular, elliptical, and / or square cross section at least in parts and / or sections. The cross section may be circular, triangular, rectangular, or polygonal. The shank and / or support part may also be formed, at least in cross section and / or in sections, into an open U-shape and / or V-shape. The tubular and / or open-shaped partial configuration provides a very robust and torsionally rigid structure, thereby enabling good force introduction and transmission and a simple and robust construction. At least in the mounting device, the shank is configured round, at least in the region of the rotatable bearing of the shank (or over an essential part of its length, or over its entire length).

[0030] The shaft and / or the support part are particularly preferably manufactured from a stainless metal material, in particular "VA steel" or other stainless steel alloys. In particular, the material surface is configured in such a way that a paint coating can be omitted. Thus, paint or paint particles are prevented from peeling, shrinking and / or wearing away due to mechanical loads and stresses, which would cause contamination. Due to the hard or hardened surface and the wear protection, possible contamination is minimized and / or does not occur.

[0031] The holding device for radiological examinations can preferably withstand loads, especially in the direction of gravity, of at least 1350 N, 1500 N, 1700 N, 2000 N or 3000 N. In a heavy load configuration, it can preferably withstand loads of up to 5000 N or more.

[0032] The radiology holding device in particular supports load moments of at least 5.5 kNm, 6.5 kNm, or in heavy load configurations, at least 10.0 kNm, or even higher. The radiology holding device may preferably be configured to support lower or higher forces and / or load moments. This depends, among other things, on the expected load. If applied primarily or only to children or particularly small and lightweight persons, the load limit may be configured much lower. In the case of special radiology systems for very obese persons, the radiology holding device may be configured for much higher loads.

[0033] It is particularly advantageous for the actuation mechanism of the holding device for radiological examinations to be actuated by at least two actuation members. The actuation members can in particular be actuated at least partially independently of one another. That is, the locking devices can be actuated separately by at least one actuation member. In a simple example, at least one section or region of the transmission element can be formed by a cable or a thread, for example. At least one actuation member can particularly preferably be configured as or include a form element such as a button, a knob, and / or a handle. Alternatively, the actuation member can be formed by a cable loop and / or a cable end. Other geometric shapes or bodies are also conceivable. In particular, three, four, five, or more actuation members can be provided. Advantageously, the actuation members are at least partially arranged and / or configured on at least one transmission element. Advantageously, the actuation members enable comfortable and particularly safe operation of the actuation mechanism. The operator can then, for example, by pulling the actuation member, and thus the transmission element, for example configured as a cable, release the locking device and simultaneously actuate and pivot the support arm to the desired position.

[0034] Furthermore, at least one actuating element is arranged in the vicinity of the holder, in particular on the support part of the support arm, so that it can be advantageously operated immediately with the holder, thus considerably improving the operating comfort in particular.

[0035] The further actuating member may also be configured as an electric sensor and / or switch. In this case, the locking device is electrically actuated via the actuating mechanism. In this case, the transmission element is preferably configured as and / or includes an electrically conductive cable. The used item is preferably driven by mechanical components rather than by a motor or electric drive.

[0036] Preferably, the actuation mechanism is actuated by at least two actuating members independent of each other. In particular, two or more actuating members are provided, by which the actuating mechanisms can be actuated separately. The at least two actuating members can be arranged on the transmission part of the series and / or parallel switch, respectively, and connected to the transfer member. The actuating members can be oriented so that actuation from different positions on the support arm is advantageously feasible. Alternatively, the actuating member can be formed by the transmission part itself. For this purpose, the actuating member can be formed by a substantially horizontal portion of the transmission part.

[0037] In at least one advantageous specific embodiment, the actuation mechanism comprises at least two force-directing units, each configured as a blocking unit. In particular, three, four, five, or even more force-directing units may be configured. Advantageously, at least one force-directing unit is configured per actuation member. Furthermore, in the case of long flexible pull elements or in the case of transmission elements, it is advantageous to provide one, two, or more force-directing units in order to ensure the reliability of the actuation of the locking device. Advantageously, multiple force-directing units can prevent and compensate for unintentional sagging or stretching of the transmission element, in particular the flexible pull element, respectively. This further improves the reliability of actuation within a substantially defined operating range.

[0038] The range of actuation of the flexible pull element is preferably less than two times the diameter of the actuation member. Advantageously, the range of actuation may be at least four, eight or even twenty times less than the diameter of the actuation member.

[0039] In at least one advantageous embodiment, the operating range of at least two actuating members substantially corresponds to the minimum range required for actuation of the actuating mechanism of the locking device. This is the minimum operating range. Preferably, the operating range of at least one other actuating member is no more than five times, in particular no more than three times, or no more than two times the minimum operating range.

[0040] The stroke length of the (minimum) working range of the transfer element is preferably less than 100 mm, in particular 50 mm to 5 mm, preferably about 15 mm. Furthermore, the working range may be up to 30 mm, up to 60 mm, or even up to 120 mm, or even longer. Advantageously, a short working range can improve the handling of the holding device for radiological examinations. The user does not have to assume an undefined working range, even during repeated operations. Accidents can therefore also be advantageously prevented.

[0041] Preferably, the range of movement required for movement between at least two, nearly all or all different actuating members varies by less than 150 mm or less than 100 mm, preferably less than 50 mm, particularly preferably less than 25 mm.

[0042] Preferably, the operating range required for actuation between at least two, nearly all or all different actuating members varies by less than 300% or 200%, preferably less than 100%, particularly preferably less than 50% or 26%. A shorter (absolute) operating range may exhibit a greater percentage deviation than a longer operating range.

[0043] In a specific configuration, the working range along the first actuating member is 15 mm, which may be up to 10 mm longer or shorter depending on the design and setup. The deviation from the working range of the second actuating member, or from the working range of (almost) all other actuating members, is in particular less than 75 mm or less than 50 mm, preferably less than 20 mm, more preferably less than 200% of the working range. However, if the normal working range is already 100 mm, the deviation from the working range of the second actuating member is in particular less than 100 mm, preferably less than 50 mm.

[0044] Advantageously, the force-directing unit includes a stopper portion for each of the at least one holding portion. The term "stopper portion" is used herein as a synonym for the term "holding portion" and can be replaced thereby throughout the present specification. Conversely, the term "stopper portion" can be replaced by the term "holding portion" in the present specification. The term "stopper portion" will be used hereinafter. The stopper portion is particularly arranged on the support arm. Preferably, the flexible pull member is at least partially accommodated, particularly at least guided and / or attached to the stopper portion. At least one stopper portion is also particularly arranged on the shaft and / or, particularly preferably, on a support part of the support arm. The stopper portion particularly constitutes, surrounds, or guides the flexible pull member. The stopper portion can also bend the flexible pull member. In this case, a separate guide element for guiding the flexible pull member is not required. Preferably, the stopper portion has a smooth contour without corners or edges for guidance. Furthermore, the stop can be supported or placed on a surrounding part or object. Advantageously, the stop allows the applied operating force to be transmitted substantially directly to the locking device.

[0045] In at least one advantageous configuration, the stop has a profile that expands with increasing radial distance from the axis of rotation. Advantageously, the expanding profile arrangement allows for guiding and deflecting the flexible pull element. Furthermore, good force reversal is possible, allowing the operating force to be applied directly to the locking device.

[0046] Preferably, the at least one stop is arranged at a radial distance from the rotation axis that corresponds to at least 20% of the maximum radial length of the support arm. Advantageously, the at least one stop is arranged at a radial distance that corresponds to at least 30%, 50%, 70% or more of the maximum length of the support arm. In particular, the stop is arranged at a radial end of the support arm. Advantageously, the at least one stop is arranged radially outside the mounting device. Advantageously, an actuating member is arranged in the vicinity of the holder. Advantageously, actuation of the holding device for radiological examinations is thus particularly comfortable. Furthermore, pivoting of the support arm can advantageously be achieved at a radial position that presents a particularly long lever arm relative to the rotation axis, so that only a small force needs to be applied by the user.

[0047] Particularly preferably, at least one actuating member capable of actuating the locking device is arranged and / or attached radially outside the mounting device. The retainer may preferably be arranged near or at the radial end, i.e., given the large radius of the support arm. Advantageously, actuation can be performed from the vicinity of the retainer.

[0048] Preferably, the force-directing unit includes at least one support. The support is preferably attached to or arranged on the flexible pull element. Particularly advantageously, the support at least partially surrounds or encloses the flexible pull element. Preferably, the support serves to support, and in particular tension, the flexible pull element. Preferably, a substantially defined position of the flexible pull element, in particular of the actuating member, can be achieved in this way. The support advantageously performs the function of a "cable stopper" and at least partially biases the flexible pull element, in particular configured as a cable, to lock its movement in an unintended direction. Thus, the operating force is transmitted substantially directly to the locking device. Therefore, the support may also be referred to as a blocking element, since it blocks the movement of the flexible pull element in one direction. Therefore, the term "blocking element" is used synonymously with the term "support element" and can be substituted therefor herein. Conversely, the term "blocking element" can be substituted therefor herein. Hereinafter, the term "block portion" will be used.

[0049] The blocking portion is in particular attached to the flexible pull piece and is received or positioned (at least partially with a force fit and / or form fit) on the flexible pull piece. In at least one advantageous specific embodiment, the blocking portion is connected to the flexible pull piece and in particular is received on the flexible pull piece via at least one node and / or loop and / or screw unit of the flexible pull piece.

[0050] The blocking portion may also be formed by a (local) bulge of the flexible pull element, for example, formed as a node or as a section enlargement with a rigid or resiliently configured bulge received in or on the flexible pull element.

[0051] Particularly preferably, the blocking portion is attached to a flexible pull piece, and the movement of the blocking portion relative to the flexible pull piece is restricted in at least one direction.

[0052] Advantageously, the block portion includes at least one receiving unit that can be at least partially closed. The flexible pull element is preferably arranged on a lockable receiving unit. Advantageously, a permanent and stable connection between the block portion and the flexible pull element can be achieved in this way. The block portion can, in particular, be locked onto the flexible pull element. For this purpose, the receiving unit, in particular the screw unit, can preferably include at least one set screw. This at least partially locks the flexible pull element onto the block portion. The position of the block portion on the flexible pull element is preferably freely adjustable. Preferably, the connection is detachable, allowing all components to be replaced. This allows particularly high hygiene requirements to be achieved. Advantageously, the block portion can at least partially protrude above the stop portion. The block portion is particularly adapted to the contour and contour layout of the stop portion. Thus, the block portion can exhibit a tapered contour layout that the stop portion receives. The block portion is configured rotationally symmetrical so as to be centered on the stop portion. Advantageously, the blocking part protrudes above the stop part at least during the application of the actuating force. Advantageously, the flexible pull element thus transmits the actuating force applied to the flexible pull element directly to the locking device. Particularly preferably, the use of the blocking part ensures safe and reproducible functioning of the force-inducing unit and the actuating mechanism.

[0053] In all possible advantageous configurations, the actuation mechanism can consist of at least two transmission parts. Preferably, the transmission parts are connected by at least one, in particular detachable, coupling unit. The coupling unit can extend the transmission parts and also allow for interchange between various transmission parts. Therefore, advantageously, a mechanical connection can be established by means of the coupling unit. Furthermore, transmission parts configured as rod members, for example, can also be connected by a flexible pull element via the coupling unit.

[0054] Preferably, the coupling unit may include at least one sleeve part. Advantageously, the coupling unit is configured from at least one screw unit. Advantageously, the transmission part is configured, in particular, as a flexible-pull part. Preferably, the sleeve part and the screw unit at least partially enclose the transmission part. The screw unit can be configured, in particular, as a set screw, through which the transmission part passes at least partially. In particular, the flexible-pull part is configured to have at least one node part. Advantageously, the node part accommodates the flexible-pull part on the coupling unit, preferably on the sleeve part and / or the screw unit. The configuration of the coupling unit allows for the connection of multiple transmission parts for quick exchange. Preferably, no tools are required to open or close each coupling unit.

[0055] In at least one advantageous specific embodiment, the transmission element is threaded through at least one hollow portion of the stem.

[0056] Since the transmission component passes through the hollow part of the shaft, the entire holding device for radiological inspection, and in particular the support arm, is particularly compact and space-saving. While the support arm is rotating, the transmission component does not have to rotate around the rotation axis of the support arm. As a result, passage through magnetic shielding is particularly easy. Even if there is a shielding or partition wall, no slots, elongated holes, linear openings, etc. are needed to allow the transmission component to rotatably pass through. Also, sealing the shielding is very easy and simple.

[0057] When a support device for radiological examinations passes through a suspended ceiling equipped with a magnetic shield (Faraday cage), the passage surface is limited to the cross-sectional area of ​​the shaft. Therefore, the shielding only needs to be opened and / or passed through over a minimum cross-section. In any case, sealing the holes in the shielding is not very complicated and may not be necessary.

[0058] Preferably, the locking device of the holding device for radiological examinations establishes a mechanical and / or geometrical connection between the support arm and the mounting device. The locking device is mechanically configured, in particular, as a friction brake and / or a belt brake, etc. The locking position is determined mechanically by the interaction of a friction film and / or a belt on the receiving part. Preferably, the friction film is accommodated or configured (e.g., integrally) in the receiving part, and the friction film is accommodated on the support arm. In this case, the support arm is clamped against rotation in the respective locked position. Alternatively, the locking position can be implemented by force engagement, for example, by a magnetically acting locking device. In this embodiment, the locking device of the support arm is held in the desired locked position directly, for example, by magnetic force, or the magnetic force is used to move the fixing part into the locked position and / or to hold it in the locked position. In these cases, any desired locking position can be realized at any desired angular position. In this case, the support arm is clamped against rotation in the respective locked position. Alternatively, the locking position can be implemented mechanically, for example, by a magnetically acting locking device. In this embodiment, the locking device of the support arm is held in the desired locking position directly, for example by magnetic force, or magnetic force is used to move the fixed part into the locking position and / or hold it in the locking position. In these cases, any desired locking position can be achieved at any desired angular position. In this embodiment, the locking device of the support arm is held in the desired locking position directly, for example by magnetic force, or magnetic force is used to move the fixed part into the locking position and / or hold it in the locking position. In these cases, any desired locking position can be achieved at any desired angular position.

[0059] However, it is particularly preferred that the locking device is form-fitting, in which case the angular position is locked by interlocking form elements. The form connection can be achieved by interlocking elements, pawls or another form contour layout.

[0060] Advantageously, the locking device includes at least one fixed part for locking the locking device. Preferably, the transmission part can be transmitted from a locked position to a rotated position, during which the angular position of the support arm can be changed relative to the mounting device. In particular, the support arm can be freely rotatable or pivotable within a predetermined angular range in the rotated position. Particularly preferably, a grid point is provided.

[0061] Preferably, when the actuating part is actuated, transmission of the transmission part by a stopper part arranged at a greater radial distance than the actuated actuating part is locked by a blocking part, so that the actuating force acts substantially on the fixed part of the locking device. In this way, a simple blocking device is realized.

[0062] The transmission part is mechanically and / or geometrically connected to the fixed part, indirectly and / or directly. Alternatively, the transmission part may be configured as an electrical conductor and / or an actuator. In this and other cases, at least one additional actuator or operating device may be configured. For example, a positioning motor may be provided that can transfer the fixed part from the locked position to the rotated position (and vice versa).

[0063] The holding device for radiological examinations can be pivoted and / or rotated by at least one actuating device, in particular by a motor, preferably an electric motor. In this case, the holding device for radiological examinations is pivoted, in particular by remote control with a wireless or wired connection to the actuating device. In this case, in a preferred variant, the holding device for radiological examinations can only be pivoted by the actuating device while it is locked in a safe locked position. Such a safety function is preferably realized by at least one safety switch. By activating such a switch, the holding device for radiological examinations can be pivoted even when it is not in the locked position.

[0064] In all configurations, the locking device preferably includes at least one fixing part that engages with at least one of the plurality of click-in elements. The fixing part is configured and / or arranged on the mounting device in particular to allow for a plurality of locking positions for fixing. The click-in element is configured in particular as a recess, preferably as a hole. The at least one fixing member (a one-piece replacement for the fixing part) is configured in particular as an engaging part that allows or establishes a positive connection with the mounting device. The at least one engaging part is advantageously configured as a bolt, which structurally engages in the locked position with a matching hole in the mounting device.

[0065] The click-in element and the fixing part preferably interact to enable a locked position. When the click-in element and the fixing part engage with each other, rotation is prevented, and when they are disengaged, the support arm can be rotated. It is particularly preferred that the click-in element is configured as a recess and the fixing part comprises a bolt or the like for insertion into the recess. A reverse operation is also conceivable, in which the fixing part presents, for example, a recess into which a click-in element, e.g., in the form of a bolt, engages in the locked position. It is also possible that the fixing part and the click-in element are configured as molded parts adapted to mechanically (and / or geometrically) engage with each other. The fixing part as a component of the locking device is preferably arranged on the support arm. A plurality of suitable click-in elements (recesses) is preferably configured and / or arranged on the mounting device.

[0066] Also, if structurally necessary, the bolt and recess can be on diametrically opposed sides of the support arm and mounting device.

[0067] The construction of the locking device with at least one bolt, each with a fastening element engaging in a circular hole, offers the advantage that the locking device is particularly simple and inexpensive to manufacture. The construction is very robust. The geometric connection is suitable for absorbing lateral forces and torques and can reliably fix the support arm in the locked position. The mechanism can be arranged centrally around the rotation axis of the support arm and in a space-saving manner.

[0068] Particularly preferably, the plurality of recesses, in particular holes, are distributed circumferentially on a disc or, for example, on a ring, in particular as (periodic, uniform) circular holes arranged on the mounting device.

[0069] Particularly preferably, the holes are arranged equidistant from one another, preferably at intervals of 5°, 10°, 15°, and / or in particular 30°, and / or in particular 45°, and / or in particular 90°. Other pitches are also conceivable. The holes may also be distributed circumferentially at non-uniform intervals. For example, a plurality of recesses may be provided in a small circumferential section, while a small number of possible locking positions are arranged in a corresponding circumferential section.

[0070] In an advantageous configuration variant, the recesses are arranged (approximately circularly) with a diameter larger than the diameter of the shank. Particularly preferably, the recesses are arranged circularly with a diameter greater than 1.5 or 2 times the (external) diameter of the shank. This is advantageous for particularly easy engagement of the bolt in the recess. Locking devices with circularly arranged recesses and fixing parts configured as bolts, cones, cone stems, etc. are particularly easy to reach. This is advantageous mainly for maintenance and repair work. Therefore, the locking device is preferably arranged immediately adjacent to the shank.

[0071] Preferably, the holding device for radiological examinations includes at least one biasing device capable of biasing the engaging element into the locked position. The biasing device particularly preferably periodically or (almost) always positions the locking element in the locked position unless the actuation mechanism positions it in the rotated position. The biasing can be realized in particular by at least one biasing spring, which urges the bolt of the fixing element into the hole in the engaged locked position in the appropriate angular position. The biasing device may preferably be configured as or at least include a compression spring, coil spring, helical spring, leaf spring, or other elastic element. It is also possible to utilize the elastic properties of other elements to bias the fixing element. The biasing device can in particular be configured as a magnetic or pneumatic mechanism.

[0072] In the case of rotational movement, the biasing device preferably automatically locks the fixed part in place when the fixed part engages the recess during rotational movement. In this way, the support arm is advantageously periodically or constantly biased to a fixed angular position.

[0073] By biasing the fixing members in the locked position, the support arms of the radiological examination support device are locked in their respective angular positions in the locked position so that they cannot rotate. A person can safely pull themselves up and / or support themselves on the radiological examination support device. The radiological examination support device is therefore used in a non-rotatable manner for transporting a person. In the event of an impact and / or jerky movement of any component of the radiological examination support device, the angular positions of the support arms are securely locked and cannot be displaced by the impact.

[0074] Preferably, the stem exhibits a shield or cover device extending, at least in a moderate range along the longitudinal axis, in particular transversely, preferably perpendicularly, to the stem. The shield serves, in particular, to cover or seal the passage through the at least one intermediate ceiling and / or magnetic shield. A magnetic shield is provided in and / or on the intermediate ceiling, in particular, providing sufficient shielding against radiation emitted by the radiological inspection device during operation. The shield closes the magnetic shield, in particular, to allow a safe and reliable operation of the radiological inspection equipment. For this purpose, a suitable material for the shield can be processed and / or integrated, in particular, into and / or on the shield. The connection between the shield and the at least one intermediate ceiling can potentially be suitable for additionally supporting the stem, which increases the system rigidity. Multiple shields may also be arranged on the stem.

[0075] An arrangement without a shield is also possible. This variant of the arrangement is particularly preferred when the holding device for radiological examinations is to be mounted in a room without an intermediate ceiling and / or on a wall. An additional covering device may be provided which completely covers, in particular, the mounting device and the locking mechanism.

[0076] The actuating element may in particular be provided with an additional protective sleeve, which protects the transmission element and the actuating mechanism from contamination, primarily from the user's hands. The protective sleeve is particularly preferably configured cylindrically and / or annularly. Other configurations are also conceivable. Preferably, the sleeve simply surrounds the transmission element. If the adjacent actuating element is configured as a knob, the sleeve can be easily supported so that it is positioned by gravity. The sleeve is particularly preferably made of an antibacterial material or material combination and is easily cleanable. The material advantageously has a smooth surface to prevent dirt from settling. Preferably, the protective sleeve has a length greater than 5 mm, in particular greater than 10 mm. Preferably, the protective sleeve is configured to have a length between 5 mm and 100 mm, in particular between 10 mm and 60 mm.

[0077] In a particularly advantageous variant, the transmission part is threaded from the inside of the axle part to a radially outer region of the axle part. The transmission part is then threaded onto the axle (without taking up any particular space). The transmission part therefore does not have to pass separately along the axle through an opening in the intermediate ceiling, which would otherwise have to be sealed. The opening required is therefore limited to the axle part and its cross section. While the support arm pivots, the transmission does not have to rotate along the axle part. The transmission part pivots substantially around the axle part.

[0078] Particularly preferably, the transmission element is accommodated and / or guided on the support element over at least one-quarter or at least half the length of the support element, in particular over at least two-thirds the length of the support element and / or advantageously over at least three-quarters the length of the support element. This particularly preferably allows the actuating element to be located near the holder. An actuating mechanism may optionally be provided for actuation by the patient. In any case, the operator can pull the actuating element and hold it radially outward at a distance to release the locking device, while at the same time guiding and rotating the support element of the support arm.

[0079] Preferably, the transmission part passes through the shank via at least one guide unit in the shank and / or at least once from the inside to the outside. Particularly preferably, the transmission part passes through a guide unit configured as a guide rail inside the shank. The guide rail is configured as a tubular section exhibiting a circular and / or elliptical and / or polygonal cross section, in particular with 3, 4, 5 and / or more corners.

[0080] As another example, the guide unit may be configured with an open profile having a U-shaped and / or V-shaped cross section. The guide unit particularly preferably guides the transmission part inside the shaft part over at least one range along the axial direction. The guide unit allows the transmission part to pass from the radial inside to the radial outside at least once and / or from the radial outside to the radial inside at least once.

[0081] The guide unit may consist of one part and / or several pieces. It may also be made of several materials. The side through which the transmission part passes may be provided with a particularly friction-reducing surface and / or a friction-reducing coating or layer, for example graphite, to facilitate and improve the movement of the transmission part. It may also be provided with a self-lubricating coating of oil and / or grease. The guide unit passes over the transmission part at least once from the inside to the outside in the radial direction and / or at least once from the outside to the inside in the radial direction.

[0082] The guide unit is advantageously made of plastic, providing a particularly smooth surface for the transmission parts to slide on. Other sides and / or positions of the guide unit may be made of a material that is particularly suitable for suspending or mounting the guide unit inside the shaft, for example steel.

[0083] The transmission element can be configured as a mechanical pull element or cable, chain, or band, which has the advantage that a button and / or knob can be attached to the end of the cable as an actuating element, thereby activating the actuating mechanism. The actuating mechanism can be operated simply and directly. In operation, the flexible pull element can easily compensate for slight changes in the position of the operator's hand, so that the actuating element can trace the movements of the patient's and / or operator's hand. The direction and / or orientation and / or local advancement of the flexible pull element can be variably arranged to suit the user's convenience, and the end of a cable can also be used directly as the actuating element.

[0084] Configuring the transmission element as a mechanical pull element provides the further advantage that at least two actuating members can be easily connected in series and / or parallel with the transfer element. The actuating mechanism is therefore advantageously actuated by at least two actuating members. The flexible pull element of the transmission element may likewise be located along the support arm, in particular along the support element. The transmission element may itself be utilized as an actuating element. The various actuating members may be radially spaced from one another to allow actuation from various positions along the support arm, in particular along the support element of the support arm.

[0085] Advantageously, the transmission part is deflected and / or guided by at least one guide roller arranged on the outside of the shaft and / or at least one guide roller arranged on the inside of the shaft. The deflection roller is preferably arranged on the shaft of the support arm. This makes guiding the flexible transmission part relative to the at least one locking device particularly advantageous. The movement of the transmission part allows for simple and direct deflection in the desired direction. The movement of the deflection roller when the actuating mechanism is activated allows for particularly low-friction guidance of the movement direction of the transmission part. Particularly preferably, at least one deflection roller is arranged adjacent to the shaft along which the transmission part passes radially outside. The deflection roller may also be arranged on the support arm and guide the flexible pull part of the transmission part along the support arm.

[0086] Particularly preferably, the transmission element is configured to be flexible by means of at least one flexible sleeve. The flexible sleeve is configured in particular as a tubular section, preferably with a circular, elliptical and / or polygonal cross section. This allows for an effective adaptation of the direction of movement of the transmission element, particularly preferably with a small radius inside. The flexible sleeve may also be configured with an at least partially open profile with a U-shaped and / or V-shaped cross section. Guides can be used in particular for changing the orientation of the transmission element inside the hollow shaft and when entering and exiting the shaft.

[0087] In a particularly preferred variant, the transmission part is threaded axially out of the axle part at least downwards. Moving the transmission part axially out of the axle part advantageously allows the direction of the flexible pull part to be deflected. The transmission part can therefore exit the axle part centrally below the axis of rotation of the support arm, allowing for a substantially central actuation of the actuation mechanism. The transmission part can therefore exit the axle part centrally below the axis of rotation of the support arm, allowing for a substantially central actuation of the actuation mechanism.

[0088] Flexure sleeves are advantageous because they allow transmission components to flex over small radii or where flexure rollers cannot be placed.

[0089] Advantageously, the holding device for radiological examinations comprises at least one limiting device for limiting the angle of rotation. The limiting device for limiting the angle of rotation may particularly preferably be arranged as a stop, for example on the mounting device, and / or attached as an attachment device. The limiting device for limiting the angle of rotation particularly preferably serves to limit the angle of rotation of the support arm to, for example, the full angle of rotation, 270°, 180°, or 90° of rotation. The specific angle depends on the specific case and the specific conditions. The angle of rotation may therefore be limited to a smaller angle, which is determined by the setting and / or pitch in the machine room and the number of possible locking positions. It is equally feasible to configure the holding device for radiological examinations without a limiting device.

[0090] Particularly preferably, the rotation angle limiting device is configured with a damping element that allows a softly damped stop. The damping element is preferably configured as a rubber pad, a gas spring, and / or rubberized. This allows the holding device for radiological examinations to be positioned and integrated into the radiological examination room, in particular to suit the requirements and needs of the radiological examination system, the patient or operator, and the geometric dimensions of the room. Preferably, the locking device can be provided with at least one stop for this purpose. The limiting device can be attached, in particular, to a wall of the room. In this case, the limiting device is not integrated into the locking device. In this way, the operating range of the holding device for radiological examinations is defined.

[0091] In a particularly advantageous variant, the holding device for radiological examinations comprises a bumper unit which surrounds the holding device for radiological examinations over a particularly large area and / or particularly completely and protects the holding device for radiological examinations (to a large extent or almost completely) from impacts and collisions with other devices in the radiology chamber during rotation.

[0092] Such a bumper unit is particularly suitable for protecting the holding device for radiological examination and / or other components of the radiological examination system from damage during operation. The damper unit particularly preferably has an (outer) diameter of at least 100 or 150 mm, in particular 250 mm and / or 350 mm. However, smaller diameters are also conceivable depending on the available installation space and the conditions of the radiological examination room. The bumper unit is particularly arranged on the support part of the support arm and / or completely surrounds the support part of the support arm. The bumper unit can also particularly at least partially surround the shaft of the support arm. Advantageously, effective protection from damage is provided.

[0093] Advantageously, the bumper unit consists of an elastic material, preferably rubber and / or plastic. The damper element can also be made of a plurality of materials, which is particularly preferred. The bumper unit can also consist of a reinforcing element, which is particularly preferred, of hard plastic or metal material.

[0094] Particularly advantageously, the holding device for radiological examinations comprises at least one receiving rail with at least one hook point or hook spot, on which at least one holding tool can be hooked. Advantageously, the receiving rail extends over at least a substantial part of the radial length of the support arm. The at least one receiving rail is arranged along the support arm. The receiving rail may be configured to be torsionally rigid so as to extend over at least 25%, 50%, 75%, or even 100% of the radial length of the support arm. However, the length of the receiving rail may also be significantly shorter than the length of the support arm. In particular, several receiving rails may be arranged along the support part. This makes the arrangement particularly torsionally rigid and can provide a high resistance moment in the event of loading with normal forces, lateral forces, and / or bending moments.

[0095] The holder in particular comprises at least one hook part for hooking onto the receiving rail, which in particular comprises at least one hook element and in particular a snap hook (carabiner) or an open hook, in the case of an open hook the legs of which are preferably dimensioned in such a way that a very large holding angle of 45° or more is achieved.

[0096] Preferably, the holder allows a holding angle of at least 45°. The holding angle is advantageously measured relative to the vertical. Preferably, the holding angle is open in the direction of the gravitational acceleration vector. Preferably, a holding angle of at most 60° or more is possible. Thus, a stable support is particularly advantageously achieved in almost all conceivable positions. Preferably, the hook part configured as an open hook can only be removed from the receiving rail at a rotation angle of 30° or more, in particular 45° or more, and particularly preferably 60° or more, relative to the vertical. The short leg is then pushed upward, and the holder with the open hook is removed. At the appropriate angle, the open hook of the holder can be reinserted into another position on the receiving rail or into another receiving rail, and the holder can be positioned in another position.

[0097] In particular, a plurality of hook points or hook spots are arranged and / or configured along a receiving rail, which is particularly preferably connected at both ends to the support arms.

[0098] In particular, at least two receiving rails are arranged along the entire length of the support arm, so that the holder can reach every point within a primarily circular range of motion.

[0099] To advantageously support the holder, at least one additional support hook can be arranged, for example, at the extreme end of the support arm or at various longitudinal points for supporting the holder (when not in use). By hooking the holder onto the support hook, the holder does not become an obstacle during the pivoting movement of the support arm. This particularly advantageously results in a simple, safe and easy holder.

[0100] The hook points or hook spots can define the locking position of the holder. The function of the receiving rail is not limited to the hook device. In particular, it can also be used to hold the infusion bag and / or the infusion of the infusion holder, respectively. Other functional uses are also conceivable. Separate infusion holders are also conceivable.

[0101] The receiving rail is particularly preferably made of stainless steel, a metallic material, in particular "VA steel" or other stainless steel alloys. In particular, the material surface is configured to avoid paint and to cause little or no wear due to mechanical abrasion. Alternatively, the receiving rail can be configured transversely or obliquely relative to the support arm, in particular the support component. It is also possible to arrange two or more receiving rails on at least one support arm. The receiving rail is advantageously configured so that the holder can be moved between several different hook points or hook spots without having to remove the entire holder from the receiving rail. Particularly preferably, two receiving rails are configured along the entire radial length of the support arm. This means that removal of the hooks is only necessary, for example, when the holder needs to be transferred from one receiving rail to another. Three or more receiving rails are also conceivable.

[0102] The hook points are preferably formed by shaped elements with which the annular elements of the retainer engage, advantageously in the case of tensile loads. The hook points or hook spots may be formed by local "valleys" in the receiving rail or limited by local "hills" between them. The position of the retainer can thus be changed along the support arm without the need to release the geometric connection between the receiving rail and the retainer. This allows the retainer's position to be easily and quickly adapted and changed between multiple positions. For this purpose, the retainer is lifted over the next hill and inserted into the next hook point. Since the retainer does not require complicated removal and installation procedures, it cannot fall during hook position changes. This minimizes the risk of injury to the user.

[0103] Particularly advantageously, the holder comprises a belt unit, which is particularly advantageously arranged between the hook portion and the grip portion. The belt unit primarily serves to facilitate the patient's standing and moving. For this purpose, the length of the enclosed belt member can be changed to suit the user's needs and conditions, especially in the case of motor assistance.

[0104] Particularly preferably, when ready for use, the belt unit is supported so as to rotate about an axis oriented transverse to the horizontal. Particularly preferably, the belt unit is supported so as to be easily slidable, such that when the holder or the holding grip of the holder is rotated, the belt unit rotates about its support point, avoiding or minimizing twisting of the belt itself. Preferably, when the holder is rotated, the belt unit rotates about its support point significantly more than the belt is twisted.

[0105] The belt is preferably formed by a wide fabric band. Advantageously, the belt does not twist at all or only slightly when used as intended. The length adjustment primarily serves to advantageously adapt the length of the support to the user and their position, allowing advantageous support and / or movement in various positions.

[0106] The motor-assisted drive of the belt unit is particularly preferably provided by a helical spring or an electric motor, in particular configured as a positioning motor. The control of the holder is particularly advantageously effected by a control device which can operate and / or control the holder directly or remotely. As an alternative configuration for the motor-assisted drive, it is also possible to use pneumatic and / or hydraulic motors.

[0107] All configurations make it possible to assist the patient to move or transport themselves independently. Furthermore, the belt unit is particularly advantageous in that it allows the patient to lift themselves with the help of the support unit or holding grips when moving. Thus, the patient can be shifted by means of a shifting unit configured as a stretcher, a chair and / or a transfer cloth. Other types and embodiments of shifting units are possible as well.

[0108] Advantageously, the assistance required from nurses and radiologists during transfers is also minimized. In the ideal case, there is virtually no need for nurses to assist with shifts. In this way, the risk of bacterial, viral and germ infections is minimized. The possibility of sexual harassment during transfers is clearly minimized. Lost working time due to psychological stress and germ infections is minimized. This improves the operability of the radiology system and also improves profitability.

[0109] Advantageously, the holding device for radiological examinations is at least partially made of a material that cannot be magnetized at all, or that is difficult to magnetize, and / or that can be magnetized only to a small extent. When operating a radiological examination device, a high-intensity magnetic field is generated. This can magnetize metallic materials that exhibit certain molecular structures and cause interactions with the radiological examination device. Therefore, all components and parts of the holding device for radiological examinations are preferably made of a material that is only slightly, and in particular not at all, magnetizable, such as plastic, aluminum, and / or stainless steel. Advantageously, however, at least a large part of the holding device for radiological examinations is made of a material that cannot be magnetized at all or that is difficult to magnetize. This makes it possible to eliminate and / or at least minimize magnetic interactions between the holding device for radiological examinations and the radiological examination device (and therefore artifacts in the images). This primarily benefits the safe and reliable operation of the radiological examination device and the high quality of the images produced thereby.

[0110] In at least one advantageous specific embodiment, at least one transmission element is at least partially threaded through a hollow portion of the support element.

[0111] Advantageously, the force-inducing unit may also be arranged at least partially inside the support part, in this way, in particular the flexible pull part can be hygienically protected against contamination.

[0112] Particularly preferably, the radiological examination system according to the invention comprises at least one radiological examination device and at least one holding device for radiological examination.

[0113] Advantageously, the radiological examination system comprises at least one receptacle for the examination of a patient by means of a radiological examination device, which receptacle is arranged at least partially in the working range of the holding device for the radiological examination. Preferably, the patient receptacle is arranged in the center of the working range of the holding device for the radiological examination, in order to make efficient use of the working range of the holding device for the radiological examination.

[0114] Further advantages and features of the present invention are shown in the exemplary embodiments described below with reference to the drawings.

[0115] The applicant reserves the right to claim separate protection for a birthing apparatus holder, particularly for a birthing apparatus such as a birthing chair, birthing stool, birthing bath, or birthing bed, comprising an attachment device for pivotally receiving at least one support arm, the support arm comprising at least one axle and at least one support part, the axle of the support arm being pivotally received in the attachment device for pivoting the support arm. The birthing apparatus holder comprises a locking device for locking the support arm in at least one locked position, and an actuation mechanism including at least one transmission part and at least one actuation member for actuating the locking device, the transmission part being configured at least in part as a flexible pull part. The birthing apparatus holder comprises at least one holding device provided for attachment to the support arm, for example for providing a holding means for the birthing woman, for example for standing up, moving, or holding on. The axle of the support arm is pivotally received in the attachment device for pivoting the support arm. The actuation mechanism has a force induction unit to transmit an operating force specifically introduced into the flexible pull element to actuate the locking device. The actuation mechanism particularly includes at least one transmission element passing through the hollow portion of the shaft. In certain embodiments, the delivery apparatus holder can comprise features as described herein with reference to the holding device for radiological examinations.

[0117] FIG. 1 is a diagram showing the configuration of a radiological examination system 100 according to the present invention. A holding device 1 for radiological examination is shown in a cross-sectional view, and a radiological examination device 50, such as an X-ray device 51, an MRT device 52, a CT device 53, or a radiotherapy device 54, is shown in a front view. The holding device 1 for radiological examination is made up of a mounting device 2. The mounting device 2 rotatably houses and supports a support arm 3. The support arm 3 is made up of a shaft portion 4 rotatably fixed to the mounting device 2, and a support component 5. Each of the support arms 3 is rotatable around a rotation axis 4a.

[0118] The mounting device 2 is currently configured as a mounting console and is fixedly attached to the ceiling of a radiotherapy room (not shown). The shield 18 is positioned at the center of the stem 4 so as to cover the opening formed by the passage of the support arm 3 through a magnetically shielded false ceiling. If the radiological examination holding device 1 does not pass through a false ceiling, the shield 18 is preferably configured to completely surround the mounting device 2.

[0119] The hook point 24 is provided with a retainer 9. The retainer 9 is formed by at least one hook portion 29. The retainer 9 is shown and explained in detail in FIG.

[0120] The holding device 1 for radiological examination is placed near a radiological examination device 50, such as an X-ray device 51, an MRT device 52, a CT device 53 or a radiotherapy device 54. The support arm 3 can be pivoted above the patient treatment couch 26 so that the holding device 9 is easily reachable by the patient.

[0121] The infusion bag 30 can also be hooked to a hook point 24 of the receiving rail 23. The hook point 24 of the receiving rail 23 is configured as a "valley" between two "hills" in the profile of the receiving rail 23. As in normal use, a tensile load applied to the holder 9 securely fixes the position of the holder 9 within the hook point 24 due to the geometric shape of the "valley." The holder 9 preferably includes a mechanically spring-driven belt unit 32, which allows the length of the holder 9 to be variably adjusted. The holder 9 is hooked to the hook point 24 by at least one hook portion 29. Furthermore, the holder 9 can be positioned across the support hook (not shown) to avoid collisions when the support arm 3 rotates.

[0122] Two receiving rails 23 are configured on the support part 5, radially adjacent to the grip knob as the actuating part 12. Each receiving rail 23 defines a plurality of hook points 24. The hook points 24 are configured as "valleys" in the receiving rail's 23 profile. The retainer 9, formed by the grip part and two hook parts, is hooked onto the hook points 24 at its ends. The "valleys" of the receiving rail 23, which function as hook points 24, are separated from each other by "hills" in the profile. Under normal use, a tensile load is applied, locking the ring loop of the retainer 9 to the hook points 24. The retainer 9 can be easily inserted over the "hills" into another hook point 24 without removing the legs of the hook parts. This results in a secure, load-bearing structure. By operating the actuating mechanism 8, the support arm 3, locked in the locked position 7 by the locking device 6, can be moved to a rotated position against the force of the biasing device 17. In the rotated position, the support arm 3 is rotatable about the rotation axis 4a of the shaft part 4.

[0123] The actuation mechanism 8 comprises three transmission elements 11. Each transmission element 11 is configured as a flexible pull element 19, or more precisely, a pull rope. The first transmission element 11 is connected to the locking device 6. The first transmission element 11 is configured as a pull rope. The first transmission element 11 passes through the hollow of the shaft 4, is guided axially downward, and then radially outward from the shaft 4, where it is positioned. The first transmission element 11 is connected to another transmission element 11 via a coupling unit 206 and extends radially outward along the support element 5. The second flexible pull element 19 extends horizontally along the support element 5, guided by a force-guiding unit 200. The flexible pull element 19 is guided downward by the force-guiding unit 200. The two force-guiding units 200 are positioned so that the actuation force transmitted to the flexible pull element 19 is directly transmitted to the actuation of the locking device 6. The central force-directing unit 200 shows another transmission piece 11 connected by another coupling unit 206. A force-directing unit 200 is provided for a third transmission piece 11 as well.

[0124] Here, the force induction unit 200 comprises a stopper portion 201, which is fixedly connected to the support part 5 of the support arm 3. A block portion 203 is disposed on the flexible pull part 19 near the stopper portion 201 and is matingly connected to the flexible pull part 19. When a user pulls the operating part 12, the block portion moves on the stopper portion 201 of the force induction unit 200, which has a longer radial distance 34a relative to the operating part 12. Therefore, the transmission of force within the transmission part 11 is controlled and transmitted by the locking device 6. When activated, the stopper portion 201 prevents the flexible pull part 19 from being pulled in the opposite direction. This allows the operating range 19a to be shortened.

[0125] The grip knob of the actuating part 12 is arranged immediately next to the receiving rail 23. This allows for comfortable and easy actuation. The stop 201 is arranged radially outward of the mounting device 2, at approximately half the length 34 of the support part 5 of the support arm 3. The second stop 201 is arranged at a radial distance that corresponds to approximately 75% of the length 34 of the support arm 3 of the holding device for radiological examinations 1. This allows for comfortable actuation by a user who is close to the holding device 9. Furthermore, a large radial distance 34a from the rotation axis 4a, i.e. with a long lever arm, makes it possible to introduce a rotational force.

[0126] When the locking device 6 is actuated by the first actuating element 12, which represents a shorter radial distance 34a relative to the rotation axis 4a, the force-guiding unit 200, which is positioned at a larger radial distance 34a, advantageously ensures that the flexible pull element 19 is not pulled out of the guide of the stop element 201. The blocking element 203 prevents the flexible pull element 19 from moving. The actuating force is thus transmitted directly to actuate the locking device 6. The force-guiding unit 200 prevents the flexible pull element 19 from unintentionally or indefinitely loosening. The actuating range 19a is defined and definable by the force-guiding unit 200. Essentially, the actuating range 19a corresponds to the stroke length required for actuating the fixed element 13, which is pulled out of the recess 14 of the locking device 6 to transfer the support arm 3 to the rotated position.

[0127] 2 is a plan view of a radiological inspection system 100 consisting of a radiological inspection device 50 and a support arm 3. The mounting device 2 shown in FIG. 1 is not shown, so the locking device 6 can be seen from above. The support arm 3 is rotatable around a rotation axis 4a of a shaft portion 4 configured as a cylindrical portion.

[0128] The locking device 6 comprises a fixed part 13, which is fixed to the support arm 3 and biased to the locked position 7 by a biasing device 17. The fixed part 13 is configured as a bolt which engages in a recess 14 of a circular hole in the locking device 6. The diameter 15 of the recess 14 is significantly larger than the diameter 16 of the shank 4. The locking device 6 is therefore arranged radially outward of the shank 4 with a simple structure, allowing for safe fixation.

[0129] There is provided a rotation angle limiting device 25. The rotation angle limiting device 25 is configured as a mechanical stopper that limits the rotation angle of the support arm 3. The stopper is fixed in the recess 14.

[0130] The impact device 28 protects the support arm 3 from impacts and protects it from damage, and at the same time constitutes an effective protection against damage to other objects.

[0131] A patient holding grip 31 is fixed on the holder 9, and a motor-driven belt unit 32 can be displaced in the vertical direction. In this case, another second holder 9 is accommodated on the support part 5.

[0132] The housing of the belt unit 32 may be provided with an operating knob 31a (see FIG. 8). The knob 31a functions to activate a winding unit, for example, driven by a winding spring (not visible because it is internally located). Operating the knob 31a automatically retracts and winds the belt (unloaded), or the belt can be pulled against the force of the winding spring. A belt length of at least 200 mm or 300 mm is preferably provided. In advantageous configurations, the length of the stretchable belt can be 500 mm, 750 mm, or even longer. This provides the advantage that, in rooms with high ceilings, the holding grip of the holder 9 can be raised high enough to avoid getting in the way when not in use, preventing head injury. It is also possible to hang unused holding grips on one of the hooks 5a.

[0133] 2 shows, in dashed lines, a variant in which the support arm 3 is accommodated or configured in the radiological inspection apparatus 50. The advantage of this is that the mounting device 2 is accommodated directly in the radiological inspection apparatus 50, making it possible to achieve a compact overall structure.

[0134] The hooks 5a shown in Figures 1 and 2 can be used to hang things, such as an infusion bag or patient documents. The hooks 5a can be attached to the side of the support part 5, for example by welding. Alternatively, the hooks 5a can be fixedly or displaceably received and attached to the support part by a tube clamp or a special attachment system.

[0135] The three force induction units 200 are arranged laterally along the support part 5 of the support arm 3. The stopper parts 201 of the force induction units 200 constitute the flexible pull part 19 and guide it horizontally along the support part 5. The stopper parts 201 of the force induction units 200 constitute the flexible pull part 19 and guide it horizontally along the support part 5.

[0136] FIG. 3 is an enlarged cross-sectional view of region I in FIG. 1, showing part of the shank 4 and the support part 5 of the holding device 1 for radiological examinations. The mounting device 2 is configured as a mounting console. The mounting device 2 can be fixed to the ceiling (not shown) of the radiotherapy room by a screw connection. A rotatable support arm 3 is accommodated and supported by the mounting device 2. For this purpose, the rotatable shank 4 is directly connected to the mounting device 2 and is arranged on the mounting device 2. The support part 5 extends transversely to the shank 4. The support arm 3 can pivot about the rotation axis 4a of the shank 4.

[0137] The locking device 6 locks the support arm 3 in the illustrated locked position 7 by means of a fixing part 13. In principle, the locking device 6 is configured as a coil spring and is biased to the locked position 7 by a biasing device 17. The support arm 3 is fixed so that it cannot rotate in the locked position 7. Therefore, the safety of the holding device 1 for radiological examinations during use can be ensured.

[0138] The actuation mechanism 8 is capable of actuating the locking device 6. The fixed part 13 is connected to a transmission part 11. The transmission part 11 is configured as a flexible pull part 19, more precisely as a pulling rope.

[0139] The transmission part 11 is guided radially relative to the shaft part 4 by guide rollers 21. The transmission part 11 is bent by the guide rollers 21. The transmission part 11 is also guided by a guide unit 20 inside the shaft part 4 passing through the guide unit. The guide unit 20 is made of a tube. This tube is bent so as to bend the transmission part 11.

[0140] The transmission part 11 protrudes axially from the lower end of the shaft part 4. A flexible sleeve 22 is attached to the lower end of the shaft part 4. The flexible sleeve 22 is configured as a conical tube or sleeve. The flexible sleeve 22 is preferably made of plastic, which exhibits a slidable, smooth surface and therefore low frictional resistance. This allows the transmission part 11 to be bent with a small radius in the direction of the support part 5 of the support arm 3. The support part 5 may be a separate part or may be configured integrally with the support arm 3.

[0141] The transmission element 11 passes through to the ceiling inside the shaft 4. Therefore, there is no need for a separate guide that passes through to the ceiling on the outside of the shaft 4. The opening to the ceiling is therefore significantly smaller than if the pull cord were simply hung straight down parallel to the axis of the shaft 4. The opening required for the magnetic shield to the ceiling is significantly smaller and easier to close than in the case of designs known from the prior art.

[0142] In the support part 5, the transmission part 11 is bent horizontally along the axis of the support part 5 and further guided along the axis of the support part 5. The second transmission part 11 is connected to the first transmission part 11 by a coupling unit 206. The force guiding unit 200 ensures optimal transmission of the actuation force. Undetermined and unintentional loosening of the flexible pull part 19 is prevented.

[0143] 4 is an enlarged explanatory view of an area of ​​the support arm 3 (see area II in FIG. 1) when the force induction unit 200 is in an activated state. The stopper portion 201 of the force induction unit 200 is firmly connected to the support part 5 of the support arm 3, for example by a screw connection or welding, and closes and guides the flexible pull part 19 like a sleeve. Furthermore, the flexible pull part 19 is guided by the stopper portion 201. The blocking portion 203 is forcefully received in the flexible pull part 19. The position of the blocking portion 203 on the flexible pull part 19 is variably adjustable.

[0144] The contour 202 of the stopper part 201 widens as the distance 34a from the rotation axis 4a increases, which advantageously allows the flexible pull element 19 on the stopper part 201 to bend downwards to allow actuation of the locking device 6. The flexible pull element 19 is bent downwards, where the actuation element 12 (not shown) is located.

[0145] The block portion 203 is spherically configured and hollow inside. The flexible pull element 19 passes through the block portion 203. The flexible pull element 19 includes a node portion 204 housed inside the block portion 203. Furthermore, the block portion 203 includes a receiving unit 205 configured as a set screw. The set screw passes through the flexible pull element 19. The set screw passes through the block portion 203. Therefore, the block portion 203 is force-connected to the flexible pull element 19.

[0146] The spherical block part 203 can be received in the stop part 201 of the force-guiding unit 200. The block part 203 is centered on the rotationally symmetrical sleeve-shaped stop part 201. The flexible pull part 19 is connected to another flexible pull part 19 by a coupling unit 206. This coupling unit 206 is formed by a node part 204. The further flexible pull part 19 is forcefully placed on the first flexible pull part 19 via the node part 204.

[0147] FIG. 5 is a cross-sectional view of one embodiment of a coupling unit 206. The coupling unit 206 is composed of a sleeve portion 207. Two transmission components 11 are disposed inside the sleeve portion 207. Each transmission component 11 has one node portion 204 configured as a flexible-pull component 19. The sleeve portion 207 of the coupling unit 206 is closed by a screw unit 208. The screw unit 208 is configured as a set screw that passes through one flexible-pull component 19. In the closed state, the two flexible-pull components 19 are connected by force. The flexible-pull components 19 are shown in dashed lines to illustrate possible arrangements of the flexible-pull components 19 on the coupling unit 206. Furthermore, further arrangements and connections of the flexible-pull components 19 are possible and contemplated. This also applies to the following figures.

[0148] 6 is a cross-sectional view of the block portion 203 of the force-directing unit 200. The block portion 203 is configured as a spherical grip. The block portion 203 is configured as a spherical sleeve portion 207. The flexible-pull element 19 is received in the block portion 203 by a node portion 204 configured therein. The block portion 203 is closed by a receiving unit 205. The receiving unit 205 is configured as a screw unit 205 so that a force connection is provided. The block portion 203 can be positioned at almost any position on the flexible-pull element 19.

[0149] FIG. 7 shows a cross-sectional view of the support part 5 of the support arm 3 of the holding device 1 for radiological examinations, taken perpendicular to the axis of the support part 5, representing region III in FIG. 1. A stopper 201 is arranged laterally on the support part 5. The stopper 201 surrounds and guides the flexible pull element 19. The blocking element 203 is not shown. It is also possible for the flexible pull element 19 to be threaded through the hollow portion of the tube element 36 of the support part 5 (see dashed line). Thus, the transmission element 11 is effectively protected from contamination. The user cannot become entangled in the flexible pull element 19. The risk of injury is minimized.

[0150] FIG. 8 is a perspective view of the holder 9 of the holding device 1 for radiological examinations according to the present invention. The holder 9 comprises a hook portion 29, which can be used to receive the holder 9 at the hook point 24 of the receiving rail 23. A further support hook 29a is arranged on the holder 9 to receive an additional object, such as an infusion bag 30. The holding grip 31 can advantageously be inverted and hooked onto the support hook 29a, thereby minimizing the risk of injury or impact. The long hook legs allow for a large holding angle 35 of up to 60° or more without the risk of the hook legs slipping off the receiving rail 23.

[0151] In FIG. 8, a knob 31a on the belt unit 32 and the holding grip of the holder 9 can be seen. The knob 31a allows the belt 32e to be pulled out via a coil spring (not visible) or against the tension of the coil spring. The holding grip is housed on a rod 32b so that it rotates together with the belt unit 32. The belt unit 32 is rotatably housed via a sliding member 32c. The sliding member 32c serves as a bearing and is housed between the upper bracket of the holder 32a and the enlarged head 32d of the rod 32b, allowing the belt unit to easily slide and rotate toward the patient. The belt 32e can essentially be twisted around itself; however, if the belt is wound diagonally and improperly, operation may be hindered. [Explanation of symbols]
