Description

Technical Field

[0001] The present invention relates to a radiology gripping device, in particular for radiology equipment, and a radiology system having such a radiology gripping device and radiology equipment, such as, in particular, a computed tomography (CT) scanner, a magnetic resonance tomography (MRT) scanner, an X-ray device, a radiotherapy device, etc. Background Art

[0002] Computed tomography (CT) scanners or magnetic resonance tomography (MRI) scanners often include a tube through which the patient is pushed or passed to obtain the desired images. Hereinafter, MRI or CT scanners will be collectively referred to as X-ray equipment. In the case of a bedridden patient undergoing X-ray, MRT, or CT imaging with the aid of such an X-ray device, the bedridden patient, i.e., lying in bed or in a wheelchair, is wheeled into a room equipped with the X-ray device and positioned next to a stretcher or treatment table. Then, before the MRI or CT procedure can begin, the patient must be transferred from the bed, wheelchair, or stretcher to the treatment table. These transfers and corrective positioning require considerable effort and time.

[0003] DE202016106093U1 has disclosed a radiological gripping device that supports and assists these actions. The adjustable support arm includes a gripping handle for the patient to hold. The support arm can be fixed at an angle. Pulling a cable releases a bolt from a hole circle so that the entire support arm can be rotated. The disadvantage is that a large space is required because the entire hole circle must pass through the intermediate top plate. This means that the magnetic seal provided in the intermediate top plate penetrates a large area. Therefore, for example, the magnetic shielding will be quite complex. The cable for releasing the bolt rotates together with the support arm. In many locations, it is not ideal for staff with smaller bodies or shorter arm spans to reach the cable. Although electric adjustment and angle fixing are basically feasible, it requires a very powerful motor that can exert sufficient rotational force when already stationary to prevent the support arm from rotating accidentally during operation. This requires considerable complexity. Summary of the Invention

[0004] It is therefore an object of the present invention to provide an improved radiology gripping device, with which a reduced complexity application in radiology is possible and with which support and assistance for the patient and the operator is achieved.

[0005] This object is achieved by a radiological gripping device having the features of claim 1 and a radiological system having the features of claim 30. Preferred specific embodiments of the invention are subject matter of the dependent claims. Further advantages and features of the invention can be gathered from the general description and the description of the exemplary embodiments.

[0006] The radiological gripping device according to the present invention is particularly designed for use with at least one radiological device, preferably at least one X-ray device, MRT device, CT device, or radiotherapy device, or similar or equivalent device. The radiological gripping device comprises a fixing device and at least one supporting arm pivotably received on the fixing device. The supporting arm comprises at least one shaft and at least one supporting member. The radiological gripping device comprises at least one locking device for locking the supporting arm in at least one angular position. The angular position is a locking position in which the supporting arm can be locked.

[0007] At least one actuating mechanism is provided for actuating, and in particular releasing and / or locking, the locking device. At least one gripping device is provided for fastening to the support arm, for example to provide a gripping mechanism for the patient. Thus, for example, the patient can grip the gripping device to help him pull himself up, transfer, reposition or displace himself. The shaft element of the support arm(s) is pivotally accommodated and, in particular, supported by a fixing device. This allows the support arm to be easily pivoted to achieve different working positions. The actuating mechanism comprises at least one transmission element extending through a hollow section of the shaft element.

[0008] The radiology gripping device according to the invention is very advantageous. A significant advantage is that it is easier to maneuver. Even small people find it easy to operate. Another significant advantage is improved hygiene, as the transfer element passes through the hollow shaft and is therefore subject to a reduced risk of contamination.

[0009] In a suitable, properly installed or ready-to-use state, the axis of rotation is oriented at least substantially vertically, approximately vertically, (almost or completely) vertically, or obliquely. The fixing device is preferably configured as a fixing bracket, which is particularly attached to, for example, the ceiling of a radiology room. In other configurations, the fixing device can also be configured as a wall mount, for example, supported on a substantially vertical room wall.

[0010] The gripping device is particularly designed as or comprises a gripping handle. The gripping device (or gripping handle) is particularly height-adjustable and can therefore be adapted to accommodate both taller and shorter persons. Preferably, the gripping device or at least one gripping handle is height-adjustable by at least 100 mm, in particular 200 or 300 mm, or 500 mm or more, for example even 1 meter or more.

[0011] The carrier or its bottom surface is preferably arranged at a height of 2250 mm or higher. The gripping device may preferably be arranged at a height of 2000 mm or higher. The fixing device may also be arranged directly on the radiological device and / or may be integrated therein and / or attached thereto. In this case or in other cases, the orientation of the axis of rotation of the carrier arm can be adjusted by an adapter. Alternatively, the handling device may be attached to a wall or floor.

[0012] The carrier arm is at least arranged and / or mounted, preferably fixedly, preferably rotatably, in particular at least pivotably, to a fixing device of the radiological gripping device. The transfer element is particularly at least partially displaced substantially axially along or in the immediate vicinity of the axis of rotation when the actuating mechanism is actuated. Preferably, the transfer element is at least partially displaced in the region of the shaft element via a shaft element, which is in particular hollow.

[0013] Because the transfer element passes through the hollow section of the shaft, the radiological gripping device as a whole, and the carrier arm in particular, is particularly compact and space-saving. The transfer element does not need to rotate about the carrier arm's axis of rotation when the carrier arm pivots. This makes it particularly easy to penetrate the magnetic shield. Pivoting the transfer element through the shielding device (if present) or the partition wall does not require any slots, elongated holes, or linear openings. Sealing or shielding is also quite easy and simple.

[0014] In the case of a conceivable radiological gripper passing through a suspended ceiling with magnetic shielding (Faraday cage), for example, the surface of the passage is limited by the cross-sectional area of the shaft. Therefore, the shielding device only needs to be opened and / or broken over a minimal cross-section. In any case, sealing the holes in the shielding device is less complex or, optionally, not required at all.

[0015] The transmission element is preferably made of a non-magnetic and / or non-conductive material. This avoids antenna effects by the transmission element. This applies in particular to the area through the shaft, and in particular through the shielding device and into or in the immediate vicinity.

[0016] The shaft and / or support member are preferably configured at least partially and / or in part along the respective longitudinal axis as a (circumferentially closed) pipe segment, which exhibits a cross-section that is at least partially and / or in part annular and / or elliptical and / or square. This cross-section can in particular be circular, triangular, quadrilateral, or polygonal. Similarly, the shaft and / or support member can be configured at least partially and / or in part as an open U-shaped profile and / or V-shaped profile. The partial configuration as a pipe segment and / or open profile provides a very strong and torsion-resistant structure. It allows for good force introduction and force transmission, as well as a simple and durable structure.

[0017] The shaft and / or the support are particularly preferably made of stainless steel, in particular VA steel or another stainless steel alloy. In particular, they are designed to be coating-free. This prevents paint or paint particles from flaking off and / or falling off and / or abrasion due to mechanical loads and stresses, which could lead to contamination. Any conceivable contamination is minimized and / or eliminated due to the hardened or hardened surface and the elimination of breakage.

[0018] In particular, the radiological gripping device can preferably withstand a load in the direction of gravity of at least 1350 Newtons (N) or at least 1500 N or 1700 N or 2000 N. In the heavy-load configuration, the radiological gripping device can preferably withstand a load of up to 5000 N.

[0019] The radiological gripping device particularly supports load moments of at least 5.5 kilonewton meters (kNm) or at least 6.5 kNm or, in a heavy-load configuration, at least 10.0 kNm. The radiological gripping device can preferably be designed to support lower or higher forces and / or load moments. This depends primarily on the expected loads. In cases where primarily or only children are to be displaced, the load limit can be designed to be considerably lower. For special radiological systems for very overweight people, the radiological gripping device can be designed for considerably higher loads.

[0020] The control mechanism of the radiological gripping device is particularly preferably operated by at least one control member. The control member can particularly preferably be designed as a button and / or a knob and / or a handle. Alternatively, the control member can be formed by a cable ferrule and / or a cable end. Other geometries or bodies are also conceivable.

[0021] The operating member can be centrally positioned directly below the support arm, in particular by extending the transmission element through a hollow shaft. Thus, the user can manipulate the central operating mechanism from a variety of positions to pivot the support arm via the operating member and the transmission element. In this case, the position of the operating member is barely or not at all altered by pivoting the support arm. This allows the operating member to be positioned at a reduced distance from the radially outward end of the support arm. This facilitates operation and pivoting, particularly for shorter individuals, if the operating position is radially distant from the axis of rotation.

[0022] The operating member can also be constructed as an electric sensor and / or switch. In this case, the locking device is electrically actuated via the operating mechanism.

[0023] Preferably, the operating mechanism can be operated by at least two (in particular mechanical) operating members that are independent of each other.In a simple case, at least one part or section of the transmission element can be formed by a cable or a wire or the like.

[0024] In particular, two or more operating members are provided, by means of which the operating mechanism can be individually operated. In particular, the two or at least two operating members are arranged at different radial distances from the central pivot or axis of rotation of the support arm. The at least two operating members can be arranged on the transfer element or connected to the transfer element in a switchable manner in series and / or parallel. The operating members can be oriented so that they can be advantageously actuated from different positions on the support arm. Similarly, the operating members can be formed by the transfer element itself. For this purpose, the operating members can be formed by approximately horizontal sections of the transfer element.

[0025] Particularly preferably, at least one operating member capable of operating the locking device is arranged and / or attached radially outside the fixing device. Advantageously, the operating member is particularly arranged in close proximity to at least one gripping device. The gripping device can preferably be arranged near or at a radial end, i.e., given a large radius of the support arm. Advantageously, the manipulation can be performed from the vicinity of the gripping device. This can even be selected by the patient if there is no significant safety risk. Furthermore, a simple actuation can be performed by at least one assistant. The operator can then, for example, pull the operating member, thereby pulling a transmission element, for example, designed as a cable, to release the locking device and, while doing so, pivot the support arm to the desired position.

[0026] Preferably, the locking device of the radiological gripping device establishes a force-fitting and / or form-fitting connection between the carrier arm and the fixing device. The locking device can be designed in a force-fitting manner, for example, as a friction brake and / or a band brake, wherein the locking position is implemented in a force-fitting manner due to the interaction of a friction lining and / or a band on the receiving part. Preferably, the friction lining is accommodated or constructed (e.g., integrally) on the receiving part, and the friction lining is on the carrier arm. In this case, the carrier arm is clamped or locked in the locking position in a non-rotatable manner. Alternatively, the locking position can be implemented in a force-fitting manner, for example by means of a magnetic locking device. In this embodiment, the locking device of the carrier arm is held in the desired locking position, for example directly by magnetic force, or the fixing component is transferred to the locking position and / or maintained in the locking position by magnetic force. In these cases, any desired locking position is possible at any desired angular position.

[0027] However, it is particularly preferred that the locking device is designed as a form fit. In this case, the angular position is locked by means of interlocking form fit components. The form fit connection can be constructed by interlocking components or by meshing or other form fit contours.

[0028] Advantageously, the locking device includes at least one fixing member for locking the locking device. Preferably, the transmission element can be transferred from a locked position into a rotational position in which the angular position of the support arm relative to the fixing device can be changed. In particular, the support arm can be freely rotatable or pivotable within a predetermined angular range in the rotational position. Particularly preferably, (fixed) grid points are provided.

[0029] The transfer element is connected to the fixed member (indirectly and / or directly, with force transmission and / or form fit). Alternatively, the transfer element can be configured as or at least include an electrical conductor and / or an actuator. In this case and in other cases, at least one additional actuator or actuating device can be included. For example, a positioning motor can be provided, by means of which the fixed member can be transferred from the locked position to the rotational position (and vice versa).

[0030] The radiological gripping device 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 radiological gripping device can be pivoted, in particular, by a remote control device having a wireless or wired connection to the actuating device. In this case, in a preferred embodiment, the radiological gripping device can only be pivoted by the actuating device when it is locked in a safe locking position. Such a safety function can preferably be overridden by at least one safety switch. Actuating such a switch allows the radiological gripping device to be pivoted even when the radiological gripping device is not in the locked position.

[0031] The actuators used are preferably not motor-driven or electrically driven.

[0032] In all configurations, the locking device preferably comprises at least one fixing member engaging with at least one of the plurality of latching elements.The fixing member is particularly configured and / or provided on the fixing device so as to enable a plurality of locking positions for fixing.

[0033] The latching element is particularly designed as a recess, and preferably as a hole or countersunk hole. The at least one fastening component is particularly designed as an engagement element that allows or establishes a positive connection with the fastening device. The at least one engagement element is advantageously designed as a screw that, in the locked position, engages positively with a matching hole in the fastening device.

[0034] The latching element and the fixing member preferably interact to enable the locked position to be achieved. When the latching element and the fixing member are engaged with each other, rotation is prevented, and when disengaged, the support arm can pivot. Particularly preferably, the latching element is designed as a recess, and the fixing member comprises a screw or the like for insertion into the recess. A reverse operation is also conceivable, wherein the fixing member, for example, comprises a recess, into which the latching element, for example in the form of a screw, engages in the locked position. The fixing member and the latching element can also be designed as matching preformed parts that interlock with each other in a form-fitting (and / or force-fitting) manner.

[0035] The fixing member as part of the locking device is preferably arranged on the carrier arm. A plurality of recesses are preferably formed and / or arranged on the fixing device.

[0036] Alternatively, the bolt and recess may be paired exactly opposite the carrier arm and securing device if this appears necessary or desirable due to the structure.

[0037] The design of a locking device using at least one screw as a fixing element or an engaging element engaging in a hole in the hole circle has the advantage of being particularly simple and inexpensive to manufacture. This design is very robust. The positive connection facilitates the absorption of transverse forces and torques and helps securely secure the support arm in the locked position. The mechanism can be arranged centrally around the support arm's axis of rotation, saving space.

[0038] Particularly preferably, a plurality of recesses, in particular holes and / or counterbores, are distributed over the circumference of a disk or, for example, a ring, in particular as a (periodic, uniform) circle of holes on the fixing device. Pivoting the support arm allows the bolt of the support arm to be fixed in various angular positions, since the bolt engages in one of the holes distributed over the circumference of the circle of holes. In this way, the support arm can be fixed in the desired locking position.

[0039] Particularly preferably, the holes are arranged equidistant from one another, preferably at intervals of 5°, 10°, 15°, and / or particularly 30°, and / or particularly preferably 45°, and / or particularly 90°. Other intervals are also conceivable. The holes can also be distributed around the circumference at uneven intervals. For example, a plurality of recesses can be provided on a small circumferential section, while only a small number of possible locking positions are provided on another corresponding circumferential section.

[0040] In an advantageous design variant, a plurality of recesses are arranged (approximately in a circle) over a diameter that is larger than the diameter of the shaft. Particularly preferably, the recesses are arranged over a circle with a diameter that is 1.5 or twice the (outer) diameter of the shaft. This is advantageous in that bolted connections are particularly easy to implement in the recesses. Locking devices with recesses arranged in a circle and fastening elements designed as bolts, cones, truncated cones, etc. are particularly easy to access. This is particularly advantageous during maintenance and repair work. Therefore, the locking device can preferably be arranged in the immediate vicinity of the shaft.

[0041] Preferably, the radiological gripping device comprises at least one biasing device, which can bias the engaging member into the locking position. The biasing device particularly preferably keeps the locking device regularly or (almost) always in the locking position, unless the operating mechanism puts it into a rotational position. It is particularly feasible to bias by at least one biasing spring, which pushes a bolt as the fixing member into the hole of the relevant locking position at a suitable angular position. The biasing device can preferably be designed as or at least include a compression spring, a coil spring, a helical spring, a leaf spring or other elastic member. It is also possible to use the elastic properties of another component to bias the fixing member. The biasing device can in particular be designed as a magnetic or pneumatic mechanism.

[0042] In the case of a rotational position movement, the biasing means preferably automatically locks the fixing member in place when the fixing member engages in the recess during the rotational movement. In this way, the carrying arm is advantageously regularly or always biased to a fixed angular position.

[0043] Due to the biasing of the fixing member in the locked position, the carrying arm of the radiology gripping device is non-rotatably locked in its angular or locked position. A person can safely pull themselves up and / or support themselves against the gripping device of the radiology device, so that the radiology gripping device can be used to non-rotatably displace the person. In the event of an impact and / or sudden movement of any component of the radiology gripping device, the angular position of the carrying arm is reliably locked and cannot be moved even by impact.

[0044] Preferably, the shaft member shows a shielding device or a covering device at least in the middle range along the longitudinal axis, and the shielding device or the covering device extends in particular transversely and preferably perpendicularly to the shaft member. The shielding device is particularly used to shield or seal the passage through at least one intermediate top plate and / or magnetic shield. In the intermediate top plate and / or on the intermediate top plate, a magnetic shield is particularly provided, which fully shields the radiation emitted from the operating radiological equipment. The shielding device particularly encloses the magnetic shield so that the radiological equipment can be operated safely and reliably. For this purpose, suitable materials for shielding can be specially processed and / or incorporated into the shielding device and / or on the shielding device. The connection of the shielding device to at least one intermediate top plate can make it suitable for additionally supporting the shaft member. This improves the rigidity of the system. Multiple shielding devices can be arranged on the shaft member.

[0045] A construction without a shielding device is also possible. This construction variant is particularly preferred if the radiology gripping device is intended for use in a room without any intermediate ceiling and / or on a wall. An additional covering device can be provided, which in particular completely covers the fixing device and the locking mechanism.

[0046] Particularly preferably, the transmission element comprises at least one flexible pull member. The flexible pull member is particularly configured as or comprises at least one cable or cord, belt, string, rubber band, and / or chain. The transmission element is particularly configured as a flexible pull member. The transmission element can be constructed in multiple parts, with at least one component being configured as or comprising a rigid rod.

[0047] The operating member can in particular be provided with an additional protective sleeve, which protects the transmission element and the operating mechanism from contamination, primarily from the user's hands. The protective sleeve is particularly preferably designed to be cylindrical and / or annular. Other configurations are also conceivable. Preferably, the sleeve can simply surround the transmission element. In the case where the adjacent operating member is designed as a knob, it can easily support the sleeve so that the sleeve positions itself by gravity. The sleeve is particularly preferably made of a material or material combination that exhibits an antibacterial finish and is easy to clean. Advantageously, the material exhibits a smooth surface so that dirt does not accumulate. Preferably, the protective sleeve has a length greater than 5 mm, in particular greater than 10 mm. Preferably, the protective sleeve is designed to be between 5 mm and 100 mm in length, in particular between 10 mm and 60 mm in length. The protective sleeve particularly follows the operating member.

[0048] In a particularly advantageous variant, the transfer element extends from the interior of the shaft to a radially outward region of the shaft. The transfer element then passes through the shaft (in a particularly space-saving manner). Consequently, the transfer element does not need to be passed separately through an opening in the intermediate top plate adjacent to the shaft, as in the prior art, which would have to be sealed separately. The required opening is therefore limited to the shaft and its cross-section. When the support arm pivots, the transfer element does not need to rotate about the shaft. The transfer element pivots essentially centrally with the shaft.

[0049] Particularly preferably, the transfer element is arranged and / or guided over at least a quarter or at least half the length of the carrier, in particular over at least two-thirds of the length of the carrier, and / or advantageously over at least three-quarters of the length of the carrier. This allows the manipulation member to be particularly preferably (always) positioned in the vicinity of the gripping device, regardless of where the gripping device is mounted. A manipulation mechanism can optionally be provided for actuation by the patient. In any case, it tends to be possible for an operator to pull the manipulation member, release the locking device, and at the same time guide the carrier of the support arm for pivoting. The radial distance of the manipulation member from the guide point for pivoting the support arm is much shorter than in the prior art. The actuation point and the pivot point are also arranged on the same radial side of the support arm to further facilitate operation.

[0050] Preferably, the transmission element passes through the shaft via at least one guide element on the inside of the shaft and / or passes through the shaft at least once from the inside to the outside. Particularly preferably, the transmission element passes through the inside of the shaft via a guide element designed as a guide rail. The guide rail is particularly designed as a pipe section having a circular and / or oval and / or polygonal cross section, particularly three, four, five, or more angles.

[0051] Alternatively, the guide unit can be designed as an open profile with a U-shaped and / or V-shaped cross section. The guide unit particularly preferably guides the transfer element along at least one section in the axial direction inside the shaft. The guide unit allows the transfer element to pass through at least once from the inside radially outward and / or at least once from the outside radially inward.

[0052] The guide unit can be single-piece and / or multi-piece. It can be made of various materials. The side through which the transfer element passes can have a special friction-reducing surface and / or be provided with a friction-reducing coating or layer (e.g., graphite) to facilitate and improve the mobility of the transfer element. Furthermore, a self-lubricating coating using oil and / or grease can be provided.

[0053] The guide unit is advantageously made of plastic, thereby providing a particularly smooth surface for the transfer element to slide over. The other side and / or position of the guide unit may comprise a material particularly suitable for suspending or otherwise mounting the guide unit inside the shaft, such as steel.

[0054] The configuration of the transmission element as a mechanical pulling member or cable, chain or belt offers the advantage that buttons and / or knobs can be attached to its ends as operating members, via which the operating mechanism can be operated. Preferably, the operating mechanism comprises at least one force direction unit. Advantageously, the force direction unit comprises at least one retaining portion, which in particular accommodates the flexible pulling member. The operating mechanism can be operated simply and directly. During operation, the flexible pulling member can easily compensate for small changes in the position of the operator's hand, so that the operating member moves along the movements of the patient's and / or operator's hand. The direction and / or orientation and / or local advancement of the pulling member can be variably set for the benefit of the user, so that the cable end can also be used directly as an operating member.

[0055] The configuration of the transfer element as a mechanical pull member offers the further advantage that at least two manipulation members can be easily connected in series and / or in parallel with the transfer element. Thus, the manipulation mechanism can advantageously be actuated by at least two manipulation members. The flexible pull member of the transfer element can be, or preferably is, mounted along the support arm, in particular along the support member. The transfer element itself can serve as the manipulation member. The various manipulation members can be radially spaced apart from one another so that they can be actuated from various locations along the support arm, in particular along the support member of the support arm.

[0056] Preferably, at least one force direction unit is included. The force direction unit allows the operating force introduced to actuate the locking device to be directly transmitted to the locking device, and the locking device is actuated using the operating force. The force direction unit preferably transmits the operating force applied to the operating member in a preferred direction. This means that the transfer element moves in the preferred direction. In the case where multiple operating members are arranged in series at different positions and the middle operating member is actuated, the force direction unit then allows the force to be introduced essentially in one direction only. The movement of the transfer element occurs essentially in one direction. Movement in the opposite direction is largely prevented. This reduces the required operating stroke because the force direction unit controls the direction of the force applied to actuate the locking device, effectively redirecting it in the desired direction.

[0057] The risk is minimized or even completely eliminated, in particular when displacing a patient, that the locking device may not be operable or may only be operable involving a very long and / or undefined actuation path.

[0058] The flexible pull or transmission element can be arranged at a greater horizontal distance from the locking device.Even in the case of a long horizontal guide of the flexible pull, the proportion of the introduced traction force or the operating stroke that does not contribute to actuating the locking mechanism is minimized.

[0059] Even in the case of a drooping flexible pull element and in the case of a plurality of pull members and / or actuating members connected in series or to one another, a defined, constant or virtually identical actuating travel can be set.

[0060] Preferably, the operating path required for actuation between at least two or almost all or all different operating members varies by less than 150 mm or 100 mm, preferably by less than 50 mm, particularly preferably by less than 25 mm.

[0061] Preferably, the operating distance required for actuation between at least two or almost all or all different operating members varies by less than 300% or 200, preferably less than 100%, particularly preferably less than 50% or 25%. Shorter operating distances may show greater percentage deviations than longer operating distances.

[0062] In a specific configuration, the operating stroke along the first operating member is 15 mm, and depending on the configuration and arrangement, it can be up to 10 mm longer or shorter. The deviation from the operating stroke of the second operating member or from the operating stroke of (almost) all other operating members is then in particular less than 50 mm and preferably less than 20 mm or preferably less than 200% of the operating stroke. However, if the normal operating stroke is already 100 mm, the deviation from the operating stroke of the second operating member is in particular less than 100 mm and preferably less than 50 mm.

[0063] The position of the flexible pull and the operating member for actuation is preferably adjustable and adaptable. This significantly facilitates the work of the nurse or operator and improves patient comfort. Intuitive operation is possible because the operating member can be pre-determined and always positioned in substantially the same position.

[0064] Overall, the maneuverability of the radiology gripping device, particularly the support arm, is improved. The reliability of the manipulator mechanism is significantly improved. The defined positioning of the transfer element and the flexible pull member protects them from excessive contamination. Advantageously, the manipulator member is always grasped in the same position. This significantly facilitates and promotes the hygiene of the radiology gripping device. Furthermore, the manipulator mechanism is significantly easier to operate and more convenient to use.

[0065] In at least one advantageous particular embodiment, the operating mechanism comprises at least two force direction units, and in particular may comprise three, four, five or more force direction units.

[0066] Advantageously, each operating member includes one or at least one force direction unit. Furthermore, in the case of long pull members or transmission elements, it may be advantageous to provide one, two, or more force direction units to ensure the reliability of actuating the locking device. Advantageously, multiple force direction units prevent or compensate for unintended drooping or stretching of the transmission element, and in particular the pull member. This enables and further improves the reliability of actuation with a substantially defined operating stroke.

[0067] Preferably, the operating stroke of the pulling member is less than twice the diameter of the operating member. Advantageously, the operating stroke can be at least four, eight, or even twenty times the diameter of the operating member. In at least one advantageous specific embodiment, the operating stroke essentially corresponds to the minimum stroke required to actuate the operating mechanism of the locking device. The stroke length or operating stroke of the transmission element is preferably and / or at most 5 mm, and in particular between 10 mm and 20 mm, and preferably about 15 mm. In addition, the operating stroke can be up to 30 mm, 60 mm, or even up to 120 mm or more. Advantageously, a short, defined operating stroke can improve the handling of the radiological gripping device. The user no longer needs to assume an undefined operating stroke. Accidents can thus also be advantageously prevented.

[0068] Advantageously, the force direction unit comprises at least one retaining portion. Preferably, the force direction unit comprises at least one bearing member. The bearing member is preferably arranged on, and particularly preferably attached to, the flexible pull member. Preferably, the retaining portion prevents significant movement of the bearing member in one direction. In particular, by virtue of the bearing member abutting or bearing against the retaining portion, further movement of the pull member in that direction is prevented. The retaining portion is particularly arranged on the support arm. Preferably, the pull member is at least partially accommodated, in particular at least guided and / or even fixed to the retaining portion. The retaining portion is particularly arranged at least on the shaft and / or at least on the support member of the support arm. In particular, the retaining portion includes, surrounds, guides, and / or retracts the flexible pull member. In this case, no separate guide member is required to guide the flexible pull member. Preferably, the retaining portion exhibits a smooth contour without any corners or edges for guidance. Furthermore, the retaining portion can be supported on or arranged on surrounding components or objects. Advantageously, the retaining portion is capable of transmitting the introduced operating force to the locking device. In a simple configuration, at least one holding portion is fixed to the carrier arm and guides the pulling member.

[0069] In at least one advantageous configuration, the profile of the retaining portion extends with increasing radial distance from the pivot axis. Advantageously, the extended profile can guide and deflect the flexible pull element. In addition, force transmission is improved.

[0070] Preferably, the at least one retaining portion is arranged at a radial distance from the pivot axis corresponding to at least 20% of the maximum radial length of the support arm. Advantageously, the at least one retaining portion is arranged at a radial distance corresponding to at least 30%, 50%, 70% or a greater proportion of the maximum length of the support arm. Advantageously, the at least one retaining portion is arranged radially outwardly of the fixing device.

[0071] Advantageously, the manipulator is arranged near the gripping device. Advantageously, actuation of the radiological gripping device is therefore particularly comfortable. Furthermore, pivoting in a radial position is advantageously possible, which exhibits a particularly long lever arm relative to the pivot axis, so that the user only needs to exert very little force.

[0072] Particularly preferably, at least one operating member capable of actuating the locking device is arranged and / or attached radially outwardly of the fixation device. Advantageously, the operating member is particularly located in close proximity to at least one gripping device. The gripping device can preferably be located near or at a radial end, i.e., given a large support arm radius. Advantageously, actuation can be performed from the vicinity of the gripping device. This can even be selected by the patient if there is no significant safety risk. Furthermore, simple actuation can be performed by at least one assistant.

[0073] Particularly advantageously, the abutment at least partially surrounds or encloses the flexible pull element. Preferably, the abutment serves to support and, in particular, to tension the flexible pull element. This advantageously allows for a substantially defined position of the pull element, and in particular the operating element. The abutment advantageously fulfills the function of a "cable stop," at least partially biasing the flexible pull element, which is in particular configured as a cable. Consequently, forces can be transmitted substantially directly to the locking device.

[0074] The abutment is particularly arranged on the pull member in a force-fitting and / or form-fitting manner. In at least one advantageous specific embodiment, the abutment is attached to or placed on a contact portion of the flexible pull member. Advantageously, the abutment includes at least one receiving element that can be at least partially closed. The receiving element is particularly configured as a threaded element.

[0075] The pull member is preferably arranged on a lockable receiving unit. Advantageously, this allows for a permanent, stable connection between the abutment and the flexible pull member. The abutment can be locked to the pull member. For this purpose, the receiving unit, and in particular the threaded unit, can preferably include at least one fixing screw, by which the pull member can be at least partially locked to the abutment. The position of the abutment on the flexible pull member is preferably freely adjustable. Preferably, the connection is detachable, and all components are replaceable. This also allows for particularly high hygiene requirements to be met.

[0076] Advantageously, the abutment can be at least partially supported on the retaining portion. Preferably, the retaining portion can receive the abutment. The abutment is particularly adapted to the contour of the retaining portion. Thus, the abutment can exhibit a conical contour. The abutment is particularly designed to be rotationally symmetrical so that the abutment is automatically centered on the retaining portion. Advantageously, the abutment is supported on the retaining portion at least during the introduction of the operating force. Advantageously, the pulling member thus transmits the operating force directly to the locking device. The use of the abutment particularly preferably ensures a safe and reproducible function of the force direction unit.

[0077] In particular, by actuating an operating member arranged at a radial distance, a retaining portion arranged at a greater radial distance than the actuated operating member partially locks the movement of the transfer element, so that the operating force acts directly on the fixing member of the locking device.

[0078] In all possible advantageous configurations, the actuating mechanism can include at least two transmission elements. Preferably, the transmission elements are connected via at least one, in particular detachable, coupling unit. The coupling unit can extend the transmission element or enable switching between various transmission elements. Thus, a friction-locking connection can advantageously be established via the coupling unit. A transmission component designed as a rod element can also be connected to a flexible pull element using the coupling unit.

[0079] Preferably, the coupling unit may comprise at least one sleeve portion. Advantageously, the coupling unit further comprises at least one threaded unit. Advantageously, the transfer element is particularly configured as a flexible pull member. Preferably, the sleeve portion and the threaded unit at least partially surround the transfer element. The threaded unit may be particularly configured as a fixing screw through which the transfer element at least partially passes. In particular, the flexible pull member is configured with at least one contact portion. Advantageously, the contact portion accommodates the pulling member on the coupling unit and preferably on the sleeve portion and the threaded unit. The configuration of the coupling unit allows for connection of multiple transfer elements for quick replacement. Preferably, the coupling unit does not require tools. Advantageously, two flexible contact portions can be interconnected in a force-fitting manner solely by means of connecting the contact portions.

[0080] Advantageously, the transfer element is deflected and / or guided by at least one guide roller arranged outside the shaft and / or at least one guide roller arranged inside the shaft. The deflection roller is preferably arranged on the shaft of the support arm. This allows the flexible pulling element to be particularly advantageously guided to the at least one locking device. The movement of the transfer element can be deflected simply and directly in the desired direction. The movement of the deflection roller when the operating mechanism is actuated allows particularly low-friction guidance of the direction of movement of the transfer element. Particularly preferably, at least one deflection roller is arranged adjacent to the shaft, from which the transfer element passes radially outwards. The deflection roller can also be arranged on the support arm to guide the flexible pulling element of the transfer element along the support arm.

[0081] Particularly preferably, the transfer element is deflected by at least one deflection sleeve. The deflection sleeve is particularly designed as a tube segment, preferably with a circular and / or elliptical and / or polygonal cross-section. This allows for efficient adaptation of the transfer element's direction of action, particularly preferably including a small inner radius. The deflection sleeve can also be designed as an at least partially open profile with a U-shaped and / or V-shaped cross-section. The guide element can be used, in particular, to change the orientation of the transfer element inside a hollow shaft element and when entering and exiting the shaft element.

[0082] In a particularly preferred embodiment, the transmission element extends axially at least downwardly from the shaft. Producing the transmission element axially from the shaft advantageously allows for the flexible pull element to be deflected. Thus, the transmission element can exit the shaft centrally below the axis of rotation of the support arm, allowing the actuation mechanism to be operated essentially centrally.

[0083] The deflecting sleeve advantageously makes it possible to deflect the transfer element, also in the case of small radii and where deflecting rollers cannot be provided.

[0084] Advantageously, the radiological gripping device comprises at least one limiting device for limiting the rotation angle. The rotation angle limiting device can be particularly preferably constructed as a stopper, for example, arranged and / or attached to the fixing device or arranged and / or fastened to the fixing device. The limiting device for limiting the rotation angle or the rotation angle limiting device is used to particularly preferably limit the rotation angle of the supporting arm to a total rotation angle, for example a rotation angle of 270°, or 180°, or 90°. The specific angle depends on the specific situation and specific conditions. Therefore, the rotation angle can be limited to a smaller total angle, which depends on the arrangement in the machine room and / or the spacing and number of feasible locking positions. It is also feasible to construct the radiological gripping device without any limiting device.

[0085] Particularly preferably, the rotation angle limit device comprises a damper component that allows a soft, damped limit stop. The damper component is preferably designed as a rubber pad and / or a gas spring and / or a rubber handle. This allows the radiology gripping device to be specifically arranged or integrated in the radiology room so as to allow its use to be adapted to the requirements and needs of the radiology system, the patient or the operator, as well as to the geometric dimensions of the room. Preferably, the locking device can be provided with at least one stop for this purpose. The limit device can in particular be attached to the room wall. In this case, the limit device is not integrated into the locking device. In this way, the working area of the radiology gripping device is limited.

[0086] In a particularly advantageous variant, the radiology gripping device comprises a damping device which particularly largely and / or particularly completely surrounds the radiology gripping device in order to protect it from (mostly or almost completely) impacts and collisions with other devices in the radiology room during pivoting.

[0087] Such a buffer unit is particularly suitable for protecting radiological gripping devices and / or other components of the radiological system from damage caused 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 in the radiology room. The buffer unit is particularly configured on the carrier of the support arm and completely surrounds the carrier of the support arm. The buffer unit can also, in particular, at least partially surround the shaft of the support arm. Advantageously, effective protection from damage is provided.

[0088] Advantageously, the buffer unit comprises an elastic material, preferably rubber and / or plastic. The damper component can also particularly preferably comprise a plurality of materials. The buffer unit can also particularly preferably comprise a reinforcement member made of a hard plastic or metal material.

[0089] Particularly advantageously, the radiological gripping device comprises at least one receiving rail having at least one hooking point or hooking area, into which at least one gripping device can be hooked. Advantageously, the receiving rail extends over at least a major part of the radial length of the support arm. At least one receiving rail is constructed along the axis of the support arm. The receiving rail can be constructed to be flexurally rigid so that it extends at least over 25%, 50%, 75% or even up to 100% of the radial length of the support arm. However, the length of the receiving rail can be significantly shorter than the length of the support arm. In particular, a plurality of receiving rails can be arranged along the support element. This makes the construction particularly torsionally rigid, so that it provides a high resistance moment under load conditions of normal and / or transverse forces and / or bending moments.

[0090] The gripping device particularly includes at least one hooking member for hooking into the storage rail. It is particularly designed as or includes at least one hooking member, and in particular a spring hook (hook) or an open hook. In particular, multiple hooking points or locations are arranged and / or configured along the storage rail. The storage rail is particularly preferably connected to the support arm at both ends. The length of the storage rail can be significantly shorter than that of the support arm. This makes the design particularly torsionally rigid, providing a high resistance moment under loads caused by normal and / or transverse forces and / or bending moments.

[0091] In particular, at least two receiving rails are provided over the entire length of the carrier arm, so that every point within the predominantly circular operating range is accessible to the gripping device.

[0092] The gripping device particularly comprises at least one hooking element for hooking into the storage rail. It is particularly designed as, or particularly comprises, at least one hook element and is particularly a spring hook (hook) or an open hook. In the case of an open hook element, the hook leg is preferably dimensioned to enable a very large holding angle of 45° or more.

[0093] Preferably, the gripping device allows a holding angle of at least 45°. The holding angle is advantageously measured relative to the vertical. The holding angle is preferably open in the direction of the gravitational acceleration vector. Preferably, holding angles of up to 60° and above are possible. Thus, a stable support can be achieved particularly advantageously in almost any conceivable position. Preferably, the gripping device can only be removed from the storage rail by means of the open hook if the angle relative to the vertical exceeds, in particular, 30° and preferably exceeds 45° and particularly preferably exceeds 60°. By pivoting the gripping device or the open hook sufficiently relative to the vertical and pushing the open hook obliquely upwards, the open hook can be removed and the gripping device can be hooked to another position on the storage rail or another storage rail with the help of the open hook.

[0094] To advantageously support the gripping device, at least one additional support hook can be provided, for example, at the end of the carrying arm or (when not in use) at various longitudinal locations for supporting the gripping device. Since the gripping device is hooked into the support hook, it does not become an obstacle during the pivoting movement of the carrying arm. This particularly advantageously allows for simple, safe, and easily variable protection of the gripping device.

[0095] The hooking point or hooking area can provide a locking position for the gripping device. The function of the storage rail is not limited to the hooking device. It can also be used to hold infusion solutions or infusion bags and / or infusion poles. Other functions are also conceivable. A separate infusion pole is also conceivable.

[0096] The storage rail is particularly preferably made of a stainless steel metal material, in particular "VA steel" or another stainless steel alloy. In particular, the material surface is designed to be coating-free and is subject to little or no wear due to mechanical abrasion.

[0097] Alternatively, the storage rails can be designed transversely or obliquely to the support arm and, in particular, the support element. It is also possible to provide two or more storage rails on at least one support arm. The storage rails are advantageously designed so that the gripping device can be moved between a plurality of different hooking points or hooking locations without having to completely unhook the gripping device from the storage rails. Particularly preferably, two storage rails are designed over the entire radial length of the support arm, each preferably covering only a portion of the length. Unhooking is then only necessary if, for example, the gripping device must be transferred from one storage rail to another. Three or more storage rails are also conceivable.

[0098] The hooking points are preferably formed by shaped components, into which the annular component of the gripping device advantageously engages under tensile load. The hooking points or hooking locations can be formed by local "valleys" in the storage rail and limited by local "hills" in between. As a result, the position of the gripping device can be changed along the support arm without releasing the form-fit connection between the storage rail and the gripping device. This allows the position of the gripping device to be adjusted and modified between multiple positions simply and quickly. To this end, the gripping device is simply pushed further into the next hooking point or lifted over the next "hill". For this purpose, the gripping device does not require complicated disassembly to prevent it from falling when changing the hooking position. The possibility of injury to the user is minimized.

[0099] The gripping device particularly advantageously comprises a strap unit. The strap unit is particularly advantageously positioned between the hooking member and the gripping member. The strap unit primarily serves to facilitate patient positioning and mobility. To this end, the length of the strap unit can be modified according to the user's needs and conditions, optionally with the assistance of a motor.

[0100] Particularly preferably, when ready for use, the belt unit is supported for rotation about an axis oriented transversely to the horizontal. Particularly preferably, the belt unit is supported for easy sliding, so that when the gripping device or the gripping handle of the gripping device is rotated, the belt unit rotates about its support point, without twisting the belt itself, or only twisting it minimally. Preferably, when the gripping device is pivoted, the rotation of the belt unit about its support point is significantly greater than the rotation of the belt if it is twisted.

[0101] The strap is preferably formed from a wide fabric strap. Advantageously, when used as intended, the strap does not twist at all, or only twists insignificantly. The length adjustment serves primarily to advantageously adapt the length of the gripping device to the user and his / her position, in order to allow for advantageous support and / or transfer in different positions.

[0102] The (motor-assisted) drive of the belt unit can particularly preferably be provided by a coil spring or, alternatively, by an electric motor specifically designed as a positioning motor. Control can particularly advantageously be provided by a control unit that can be operated and / or controlled directly on the gripping device or by remote control. Alternatively, a motor-assisted drive in the form of a pneumatic and / or hydraulic motor is also conceivable.

[0103] In all configurations, the patient can actively assist in self-displacement or transfer. Furthermore, the belt unit particularly advantageously enables the patient to lift themselves with the aid of a support unit or gripping handles to assist in their transfer. Thus, a patient can be transferred using a support unit configured as a stretcher, chair, or transfer sheet. Other types and embodiments of support units are also possible.

[0104] Advantageously, the need for assistance from nursing staff or radiology personnel during relocation is also minimized. Ideally, nurse assistance with relocation is essentially unnecessary. This minimizes the risk of bacterial, viral, and pathogenic infections. Loss of working time due to stress or the spread of germs is significantly minimized. This significantly improves the operability and profitability of the radiology system.

[0105] Advantageously, the radiological gripping device is at least partially made of a material that is not magnetizable at all or is only difficult to magnetize and / or is only slightly magnetizable. Operating radiological equipment can generate high-intensity magnetic fields. Therefore, metallic materials that exhibit a specific molecular structure can become magnetized, which can lead to interactions with the radiological equipment. Therefore, all parts and components of the radiological gripping device are preferably manufactured only from slightly and in particular not magnetizable materials, such as plastic and / or aluminum and / or stainless steel. However, advantageously, at least the majority of the radiological gripping device is at least partially made of a material that is not magnetizable at all or is only difficult to magnetize. This allows to exclude and / or at least minimize magnetic interactions between the radiological gripping device and the radiological equipment (and the resulting artifacts in the image). This is primarily for the safe and reliable operation of the radiological equipment and the high-quality images produced thereby.

[0106] Particularly preferably, the radiology system according to the invention comprises at least one radiology device and at least one radiology gripping device.

[0107] In at least one advantageous embodiment, at least one transmission element extends at least partially through the hollow section of the carrier. Advantageously, the force direction unit can also be arranged at least partially on the inside of the carrier. This allows the tension member to be protected from contamination in a particularly hygienic manner.

[0108] Advantageously, the radiology system comprises at least one patient receiving portion for examination with the aid of the radiology device, the patient receiving portion being arranged at least partially within the operating range of the radiology gripper. Preferably, the patient receiving portion is located in the center of the operating range of the radiology gripper so that the operating range of the radiology gripper can be efficiently utilized.

[0153] Figure 1 The diagram shows a first embodiment of a radiology system 100 according to the present invention. A radiology gripper 1 is shown in cross-section, while a radiology device 50, such as an X-ray device 51, an MRT device 52, a CT device, or a radiotherapy device 54, is shown in front view. The radiology gripper 1 includes a fixture 2 that pivotally accommodates and supports a carrier arm 3. The carrier arm 3 includes a shaft 4 pivotally mounted to the fixture 2 and a carrier 5.

[0154] The fixture 2 is configured as a fixed bracket and is fixedly mounted to the ceiling of the radiology room (not shown). The shaft 4 is centrally provided with a shielding device 18 for shielding the opening formed by the support arm 3 passing through the magnetically shielded intermediate ceiling. In the case where the radiology gripping device 1 does not pass through the intermediate ceiling, the shielding device 18 is preferably configured so that it completely encloses the fixture 2.

[0155] The radiology gripping device 1 is arranged near a radiology system 50, such as an X-ray system 51, an MRT system 52, a CT system 53 or a radiotherapy system 54. The carrier arm 3 can be pivoted above the patient table 26 so that the gripping device 9 is easily accessible to the patient.

[0156] Along the carrier 5, two storage rails 23 are configured with multiple hooking points 24 along the entire length of the carrier 5. A gripping device 9 is hooked into the hooking points 24 of the storage rails 23, which the patient can grasp for support during displacement and positioning. An infusion bag 30 can be hooked into the hooking points 24 of the storage rails 23. The hooking points 24 of the storage rails 23 are configured as a "valley" between two "hills" in the outer contour of the storage rails 23. Due to the "valley" geometry, the tensile load applied to the gripping device 9 during normal use fixes the gripping device 9 in a form-fitting manner into the hooking points 24. The gripping device 9 includes a motor-driven or, preferably, mechanically or spring-driven belt unit 32, by means of which the length of the gripping device 9 is variably adjusted. Support hooks 29a for the gripping device 9 are provided at the ends of the carrier 5. The gripping device 9 can be placed on the support hook 29 a so that it does not interfere when pivoting the carrier arm 3 .

[0157] The storage rails 23 are configured as gripping knobs, serving as operating members 12, on the carrier 5 in radial proximity. Each storage rail 23 includes a plurality of hooking points 24. These hooking points 24 are configured as outer "valleys" in the profile of the storage rail 23. The gripping device 9, formed by the gripping member and two hooking members, is hooked into the furthest hooking point 24 among the plurality of hooking points 24. The plurality of "valleys" of the storage rail 23, serving as hooking points 24, are separated from one another by "hills" in the profile. The tensile load applied during normal use secures the position of the annular ring of the gripping device 9 to the hooking point 24. The gripping device 9 can be easily pushed over the "hill" into another hooking point 24 without having to remove the hook's legs. This creates a secure structure that exhibits load capacity.

[0158] Manipulating the actuating mechanism 8 allows the carrying arm 3 locked in the locking position 7 by means of the locking device 6 to be displaced into the rotated position against the force of the biasing device 17. In the rotated position, the carrying arm 3 can pivot about the rotation axis 4a of the shaft 4.

[0159] The transmission element 11 is configured as a flexible pull member 19 and is connected to the locking device 6. The transmission element 11 is configured as a pull cord, which is axially downwardly passed through the hollow section of the shaft 10 and outwardly passed through the shaft 4, and is radially guided and arranged along the carrier 5. One of the operating members 12 can operate the operating mechanism 8. A protective sheath 27 is provided on the transmission element 11 to protect it from contamination. The transmission element 11 and the knob, etc., form a cable loop.

[0160] A knob as the operating member 12 is provided in close proximity to the storage rail 23. This allows for comfortable and simple operation.

[0161] Figure 2A plan view of a radiology system 100 according to a first embodiment is shown, which includes a radiology device 50 and a carrier arm 3. A fixing device 2 (see Figure 1 ) is not shown so that the locking device 6 is visible in the top view. The carrying arm 3 is pivotable about the rotation axis 4a of the shaft element 4 which is designed as a tube segment.

[0162] The locking device 6 includes a fixing member 13 fixed to the carrier arm 3 and biased in the locked position 7 by a biasing device 17. The fixing member 13 is configured as a bolt that engages in a recess 14 in a hole circle 15 of the locking device 6. The diameter of the plurality of recesses 15 is significantly larger than the diameter of the shaft member 16. Therefore, the locking device 6 can be arranged radially outside the shaft member 4 with a simple structure, thereby ensuring secure positioning.

[0163] A rotation angle limiting device 25 is provided. The rotation angle limiting device 25 is configured as a mechanical stopper that limits the rotation angle of the carrying arm 3. The stopper is fixed into the recess 14.

[0164] The impact-absorbing device 28 protects the carrying arm 3 from impacts and damage. At the same time, the impact-absorbing device 28 constitutes an effective protection to prevent damage to other objects.

[0165] On the gripping device 9 , a patient support unit 31 is fastened, wherein a belt unit 32 can be displaced upwards and downwards.

[0166] The housing of the belt unit 32 may be provided with an operation button 31a (see Figure 11 ), which is used to actuate a winding unit driven, for example, by a winding spring (not visible because it is arranged inside). When the operating button 31a is operated, the belt can automatically retract and roll up (without being subjected to load) or the belt can be pulled out by overcoming the force of the winding spring. Preferably, a belt length of at least 200 or 300 mm is provided. In an advantageous configuration, the extendable belt length can be 500 mm or 750 mm or more. In rooms with a high ceiling, this provides the advantage that, when not in use, the gripping handle of the gripping device 9 can be raised high enough so as to be out of the way when not in use and to prevent it from hitting a person's head. Alternatively, the unused gripping handle can also be hung in a hook 5a.

[0167] Figure 2 A variant is shown in dashed lines, in which the support arm 3 is attached to or built into the radiology device 50. This has the advantage that the fixing device 2 is attached directly to the radiology device 50, so that a compact design can be achieved overall.

[0168] Figure 1 and 2The hook 5a shown in the figure allows objects to be hung. For example, an IV bag or a patient file can be attached to it. The hook 5a can be attached to the side of the carrier 5, for example by welding. The hook 5a can also be fixedly or displaceably positioned and fastened to the carrier using a pipe clamp or a special fastening system.

[0169] Figure 3 An enlarged cross-sectional view of the shaft member 4 and a portion of the support member 5 of the radiology gripping device 1 according to the first embodiment is shown. The fixture 2 is configured as a fixed bracket. The fixture 2 can be fastened to the ceiling of a radiology room (not shown) by a threaded connection. A pivotable support arm 3 is accommodated in and supported by the fixture 2. For this purpose, the pivotable shaft member 4 is directly connected to the fixture 2 and is arranged on the fixture 2. The support member 5 extends transversely to the shaft member 4. The support arm 3 is pivotable about the central rotation axis 4a of the shaft member 4.

[0170] The shaft 4 passes through the middle top plate. The middle top plate is only outlined with a dotted line and is not fully shown.

[0171] Shielding device 18 is centrally positioned around shaft 4. This closes and covers the opening in the intermediate top plate. This effectively shields or closes the magnetic shield located in or on the intermediate top plate. Shielding device 18 includes the magnetic shield so that the remaining opening of the magnetic shield is as small as possible.

[0172] The locking device 6 locks the carrier arm 3 in the illustrated locking position 7 via a fixing member 13. Typically, it is biased in the locking position by a biasing device 17, which is currently configured as a coil spring. The carrier arm 3 is non-rotatably fixed in the locking position 7. This ensures safe use of the radiology gripping device 1.

[0173] The operating mechanism 8 can operate the locking device 6. The fixing member 13 is connected to the transmission element 11. The transmission element 11 is configured as a flexible pull member 19, specifically a pull rope.

[0174] The transfer element 11 is radially guided to the shaft 4 via guide rollers 21. The transfer element 11 is radially guided from the outside through the wall of the shaft 4 to the inside (and vice versa) by a guide unit 20. On the inside of the shaft 4, the transfer element 11 is guided by the guide unit 20 along the axis of the shaft 4. The guide unit 20 is currently designed as a tube. The tube is curved to deflect the transfer element 11.

[0175] At the lower end of the shaft 4, the transfer element 11 extends axially beyond the shaft 4. A deflection sleeve 22 is attached to the lower end of the shaft 4. The deflection sleeve 22 is constructed as a conical tube segment or sleeve. The deflection sleeve 22 is preferably made of a plastic with a particularly slidable and smooth surface, thus providing low frictional resistance. This allows the transfer element 11 to be deflected with a small radius toward the carrier of the carrying arm 3. The carrier 5 can be a separate component, or it can be integrally formed with the carrying arm 3.

[0176] The transmission element 11 passes through the intermediate top plate on the inside of the shaft 4. Therefore, it does not require a separate guide through the intermediate top plate on the outside of the shaft 4. The opening of the intermediate top plate is therefore significantly smaller, with the pull cord simply hanging straight down and parallel to the axis of the shaft 4. The opening required for the magnetic shield in the intermediate top plate is significantly smaller and easier to close than in designs known from the prior art.

[0177] At the carrier 5, the transfer element 11 is deflected along the axis of the carrier 5 and further guided along the axis of the carrier 5. The transfer element 11 forms a cable ferrule guided on another guide member. A knob is attached radially outside the guide member. The knob and the cable ferrule together serve as a manipulation member 12 that can manipulate the manipulation mechanism 8.

[0178] The two storage rails 23 are configured as knobs on the carrier 5, radially adjacent to the operating member 12. Each of the storage rails 23 includes a plurality of hooking points 24. The hooking points 24 are configured as "valleys" in the outer contour of the storage rail 23. The gripping device 9, formed by the gripping member and two annular rings, is hooked to the furthest hooking point 24 among the multiple hooking points 24. The multiple "valleys" of the storage rail 23, serving as hooking points 24, are separated from each other by "hills" in the outer contour. The tensile load applied during normal use fixes the position of the annular rings of the gripping device 9 to the hooking points 24. The gripping device 9 can be easily pushed over the "hills" and into another hooking point 24 without having to open the annular rings. This creates a secure structure that exhibits load capacity.

[0179] Figure 4 The figure shows a radiology system 100 according to the present invention according to a second exemplary embodiment. Here, a transmission element 11, designed as a flexible pull element 19, is guided horizontally along a support arm 3. A total of three force direction units 200 are provided. These force direction units 200 ensure actuation with a uniform actuation path 19a.

[0180] The fixture 2 is currently configured as a fixed bracket and is fixedly mounted to the ceiling of the radiology room (not shown). A shielding device 18 is centrally located on the shaft 4 to shield the opening formed by the support arm 3 passing through the magnetically shielded intermediate ceiling. If the radiology gripping device 1 does not pass through the intermediate ceiling, the shielding device 18 is preferably configured so that it completely encloses the fixture 2.

[0181] At the hooking point 24, a gripping device 9 is provided, which is formed by a gripping piece showing at least one hook member. Figure 11 Shown and described in detail in .

[0182] The operating mechanism 8 includes a total of three force transmission elements 11, all of which are configured as flexible pull members 19, or more precisely, pull cables. The first transmission element 11 is connected to the locking device 6. It is configured as a pull cable, which is guided outward through the hollow section of the shaft 10 and radially directed toward the support 5, where it is located. The shaft 10 extends axially downward from the shaft 4. The first transmission element 11 is shown with another transmission element 11, which is connected to the first transmission element via a coupling element 206 and extends further radially outward along the support 5. The second pull member 19 extends horizontally along the support 5 and is guided to a force direction unit 200. The flexible pull member 19 is guided and deflected downward in the force direction unit 200. Two force direction units 200 are provided to directly transmit the operating force introduced into the flexible pull members 19, thereby directly actuating the locking device 6. The third transmission element 11 is connected to the central force direction unit 200 via another coupling element 206. A force direction unit 200 is also provided for the third transmission element 11 .

[0183] Here, the force direction unit 200 includes a retaining portion 201, which is fixedly connected to the support 5 of the support arm 3. Near the retaining portion 201, the flexible pull element 11 is provided with a bearing element 203, which is connected to the flexible pull element 19 in a force-transmitting manner. When the user pulls on the operating member 12, the bearing element moves on the retaining portion 201 of the force direction unit 200, which has a longer radial distance 34a than the operating member 12. This ensures a controlled transmission of force within the transmission element 11 to the locking device 6. During operation, the flexible pull element 19 cannot be pulled back out of the guiding retaining portion 201. This preferably ensures a short and defined operating stroke 19a.

[0184] The gripping knob of the manipulating member 12 is arranged in close proximity to the storage rail 23. This allows for comfortable and simple manipulation. The retaining portion 201 is arranged radially outside the fixing device 2 and approximately halfway along the length 34 of the carrier 5 of the carrying arm 3. The second retaining portion 201 is arranged at a radial distance 34 that corresponds to approximately 75% of the length 34 of the carrying arm 3 of the radiology gripping device 1. This allows for comfortable manipulation by the user near the gripping device 9. Furthermore, with a large radial distance 34a from the axis of rotation 4a (i.e., including a long lever arm), the forces for pivoting can be introduced.

[0185] When the locking device 6 is manipulated via the first manipulation member 12, which is positioned at a shorter radial distance 34a from the rotation axis 4a, the force direction unit 200, positioned at a greater radial distance 34a, advantageously ensures that the pulling member 19 cannot be pulled out of the guide of the retaining portion 201. The abutment 203 limits the movement of the flexible pulling member 19. Thus, the operating force is directly transmitted to the locking device 6 for manipulation. The flexible pulling member 19 cannot sag unintentionally or indefinitely due to the force direction unit 200. The manipulation stroke 19a is determined and determinable by the force direction unit 200. Essentially, the manipulation stroke 19a corresponds to the stroke length required to manipulate the fixing member 13, causing it to be pulled out of the recess 4 of the locking device 6 to shift the support arm 3 into the rotated position.

[0186] Figure 5 A plan view of a radiology system 100 according to a second embodiment is shown, which includes a radiology device 50 and a carrier arm 3. The fixing device 2 (see Figure 4 ) is not visible so that the locking device 6 is visible in the top view.

[0187] Three force direction units 200 are arranged laterally along the carrier 5 of the carrier arm 3. The retaining element 201 of the force direction unit 200 contains and guides the flexible pull element 19. Abutment 203 is fixedly connected to the flexible pull element 19. During manipulation, the abutment 203 moves together with the flexible pull element 19. The manipulation member 12 is not visible here.

[0188] Figure 6 An enlarged cross-sectional view of the shaft member 4 and part of the carrier member 5 of the radiological gripping device 1 according to the second embodiment is shown. Figure 4 The fixture 2 is configured as a fixed bracket. The fixture 2 can be fastened to the ceiling (not shown) of the radiation room via a threaded connection. A pivotable support arm 3 is accommodated and supported by the fixture 2. For this purpose, a pivotable shaft 4 is directly connected to and disposed on the fixture 2. A support member 5 extends transversely to the shaft 4. The support arm 3 is pivotable about the central rotation axis 4a of the shaft 4.

[0189] The locking device 6 locks the carrier arm 3 in the illustrated locking position 7 via the fixing member 13. The fixing member 13 is biased in the locking position 7 by a biasing device 17, which is in the present case configured as a coil spring. The carrier arm 3 is fixed in the locking position 7 in a non-rotatable manner. Thus, the safety of the use of the radiology gripping device 1 is ensured.

[0190] The operating mechanism 8 can actuate the locking device 6. The fixing component 13 is connected to the transmission element 11. The transmission element 11 is designed as a flexible pull element 19, more precisely as a pull cable.

[0191] The transfer element 11 is radially guided toward the shaft 4 by means of guide rollers 21. The transfer element 11 is deflected by the guide rollers 21 and guided along the axis of the shaft 4 by a guide unit 20 on the inside of the shaft 4. The guide unit 20 currently comprises a tube. The tube is curved to deflect the transfer element 11.

[0192] At the lower end of the shaft 4, the transfer element 11 extends axially beyond the shaft 4. A deflection sleeve 22 is attached to the lower end of the shaft 4. The deflection sleeve 22 is constructed as a conical tube segment or sleeve. The deflection sleeve 22 is preferably made of a plastic material that exhibits a particularly slidable and smooth surface, thereby providing low frictional resistance. This allows the transfer element 11 to be deflected with a small radius toward the carrier 5 of the carrying arm 3. The carrier 5 can be a separate component, or it can be integrally formed with the carrying arm 3.

[0193] At the carrier 5 , the transfer element 11 is deflected horizontally along the axis of the carrier 5 and guided further along the axis of the carrier 5 . The second transfer element 11 is connected to the first transfer element via a coupling unit 206 . The force direction unit 200 ensures optimal transmission of the introduced operating forces. This prevents the flexible pull element 19 from sagging undefined and, most importantly, unintended.

[0194] Figure 7 An enlarged view of the region of the carrier arm 3 with the force direction unit 200 of the radiological gripping device 1 according to the second embodiment is shown in the manipulated state, see Figure 4 Region II. The retaining portion 201 of the force direction unit 200 is securely connected to the support member 5 of the support arm, for example, by threading or welding, thereby sleeve-likely surrounding the flexible pull member 19. The abutment is force-coupled to the flexible pull member. The spherical abutment 203 is securely connected to the pull cord. The position of the abutment 203 on the flexible pull member 19 is adjustable.

[0195] The profile 202 of the retaining portion 201 widens with increasing distance from the axis of rotation 4a. This allows for advantageous deflection of the flexible pull member 19 on the retaining portion 201 to actuate the locking device 6. The profile 202 of the retaining portion is funnel-shaped. The pull member 19 deflects downward, where the operating member 12 (not shown) is located.

[0196] The abutment 203 is spherical and hollow inside. The pulling member 19 passes through the abutment 203. The pulling member 19 has a contact portion 204 that faces inwardly into the abutment 203. Furthermore, the abutment 203 includes a threaded element 205 configured as a set screw. The pulling member 19 passes through the set screw, which is screwed into the abutment 203. Thus, the abutment and the pulling member 19 are connected in a force-fitting manner.

[0197] A spherical abutment 203 can be placed on the retaining portion 201 of the force direction unit 200. The abutment 203 can be centered within the rotationally symmetrical, sleeve-shaped retaining portion 201. The pull member 19 is shown connected to another pull member 19 in a force-fitting manner via a coupling unit 206. This coupling unit is formed by a contact portion 204. The other pull member 19 is force-fittedly attached to the first pull member 19 via the coupling unit 206 and securely connected thereto. This coupling unit is formed by the contact portion 204. The other pull member 19 is force-fittedly attached to the first pull member 19 via the coupling unit 204.

[0198] Figure 8 The embodiment of a coupling unit 206 according to a second embodiment is shown in a cross-sectional view. The coupling unit 206 includes a sleeve portion 207. Two transmission elements 11 are arranged inside the sleeve portion. A contact portion 204 is formed on the transmission element 11, which is currently configured as a flexible pull member. The sleeve portion 207 of the coupling unit 206 is closed by a threaded element 208. The threaded element 208 is currently configured as a set screw, through which one of the pull members 19 passes. In the closed position, the two pull members 19 are connected in a force-fitting manner. The illustration of the pull members 19 using dashed lines is intended to illustrate a possible arrangement of the flexible pull members 19 on the coupling unit 206. Furthermore, other arrangements and connections of the pull members 19 are possible and contemplated. This also applies to the following figure.

[0199] Figure 9 A cross-sectional view of a bearing element 203 of a force direction unit 200 according to a second embodiment is shown. The bearing element 203 is spherical. It is configured as a spherical sleeve portion 207. The pull member 19 is received in the bearing element 203 via a contact portion 204 configured on the pull member. The bearing element is closed by a receiving element 205, which is currently configured as a threaded element 205, to achieve a force-fit connection. The bearing element 203 can be positioned at virtually any desired location on the flexible pull member 19.

[0200] Figure 10 A cross-sectional view of a carrier 5 of a carrier arm 3 of a radiological gripping device 1 according to a second embodiment is shown, wherein the carrier arm 3 is transverse to the axis of the carrier 5, see FIG. Figure 4 Region III. The retaining portion 201 is arranged transversely on the carrier 5. The retaining portion 201 surrounds and guides the flexible pull member 19. The abutment 203 is not shown. It is also possible for the pull member 19 to pass through a hollow section of the tube 36 of the carrier 5. This advantageously protects the transmission element 11 from contamination. The user cannot become entangled in the pull member 19. In this case, the risk of injury is particularly minimized.

[0201] Figure 11A perspective view of a gripping device 9 for a radiology gripping device 1 according to a second embodiment of the present invention is shown. The gripping device 9 includes a hook member 29, with which the gripping device can be stored in a hooking point 24 of a storage rail 23. A further support hook 29a is provided on the gripping device 9 to accommodate additional objects, such as an infusion bag 30. The gripping gripper 31 can advantageously be flipped upward and hooked into the support hook 29a. This minimizes the risk of injury and shock. The long leg of the hook allows for a large holding angle 35 of up to 60° or more without the risk of the leg of the hook slipping out of the storage rail 23.

[0202] exist Figure 11 In the figure, one can recognize the operating button 31a constructed on the belt unit 32 and currently on the gripping gripper of the gripping device 9, in order to pull out the belt 32e by means of a coil spring (not shown and arranged internally) or to pull out the belt 32e against the tensile force of the coil spring. The gripping gripper is attached to a rod 32b that rotates together with the belt unit 32. The belt unit 32 is accommodated to pivot via a sliding member 32c. The sliding member 32c acts as a supporting unit and is accommodated between the upper bracket of the retaining seat 32a and the enlarged head 32d of the rod 32b so as to enable easy sliding pivoting of the belt unit towards the patient. Although the belt 32e can basically be twisted around itself, if the belt is wound askew and incorrectly, it can cause problems during operation.
