Description

Technical Field

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

[0002] Computed tomography (CT) scanners or magnetic resonance imaging (MRI) scanners often include a channel through which the patient is pushed or passed to obtain the desired images. In the following text, MRI scanners, computed tomography scanners, or X-ray equipment will be referred to uniformly as X-ray equipment.

[0003] In cases where bedridden patients will undergo X-ray, MRI, or CT imaging using such X-ray equipment, the patient—whether lying in bed or in a wheelchair—is wheeled into a room equipped with the X-ray equipment and positioned next to a stretcher or treatment table. Then, before beginning the MRI or CT procedure, the patient must be transferred from the bed, wheelchair, or stretcher to the treatment table. These transfers and repositioning require considerable force and time.

[0004] DE202016106093 U1 and unpublished or subsequently published document DE102019119025.8 (DE102019119025A1) have disclosed radiographic gripping devices that can be used to support and assist these movements. A pivotable support arm includes a gripping hand for the patient to hold. The support arm is pivotable and its angle can be fixed. Pulling a cable with a ball-holding attachment at one end releases a bolt from a bore, thereby releasing the support arm and subsequently rotating it due to this actuation.

[0005] In DE102019119025.8, the pull rope can also be guided horizontally further outward along the bearing arm by means of a guide sleeve, so that it can be actuated not only centrally but also further outward radially. This is advantageous and simplifies operation. However, its disadvantage is rope slack. The rope needs to be tightened before the bolt release bearing arm can rotate. Depending on the position of pulling the rope, it is also possible to pull the rope (backward) out of the guide without moving the release bolt. The actuation stroke required for the release bolt by the slack rope depends on the position where the tension is applied. In addition, pulling the slack rope may change the position of the adjacent grip ball, which is connected to a position further away from the pivot axis of the bearing arm, thus moving the grip ball to an unreachable position. The pulling stroke for releasing the bolt is not determined and is unpredictable to the user, especially in the case of multiple actuations. Therefore, there is a risk of unpredictable bolt release when personnel change. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide a radiographic gripping device that is easy to operate. Preferably, reliable actuation can be achieved. Hygiene should also be particularly improved.

[0007] This objective is achieved by the radiographic gripping device and radiographic system provided by the present invention. The present invention also provides preferred specific embodiments. Further advantages and features of the invention can be appreciated from the general description and the description of the embodiments.

[0008] The radiographic gripping device according to the invention is specifically designed for at least one radiographic device, preferably for at least one X-ray device, MRT device, or CT device, or radiotherapy device, or similar or equivalent device. The radiographic gripping device includes a fixing device and at least one support arm pivotally mounted on the fixing device. The support arm includes at least one shaft and at least one carrier member. The shaft of one or more support arms is pivotally received and specifically supported to the fixing device. The radiographic gripping device includes at least one locking device for locking the support arm in at least one pivot position or angular position (particularly one of a plurality of operating positions). This angular position is the locked position in which the support arm can be locked.

[0009] An actuation mechanism is provided, comprising at least one transmission element and at least one actuating member, for actuating and, in particular, releasing and / or locking the locking device. The transmission element is at least partially configured as a flexible tension member.

[0010] At least one gripping device is provided for fastening to the support arm, for example, providing a gripping mechanism for the patient. Thus, the patient can, for example, grasp the gripping device to help pull themselves up, transfer, reposition, or move themselves. This particularly allows for easy pivoting of the support arm to achieve different working positions. The actuation mechanism shows at least one force direction unit for controlled use or guidance to the locking device, transmitting an operating force (between the two ends) to the flexible traction member for actuating the locking device. The force direction unit prevents the transmission of force (via the flexible traction member) in one direction. In particular, radially inward force transmission is prevented. Preferably, radially inward mobility of the traction member is prevented.

[0011] Since force direction elements prevent the transmission of force in one direction, force direction elements can be called or constructed as locking elements.

[0012] Flexible traction elements particularly (at least partially) comprise rope-like components. The traction element may particularly be at least partially constructed as or comprise at least one rope, belt, cable, flexible filament, or the like. Preferably, the flexible traction element is at least partially constructed to be elastic. Plastic deformation may also be provided within certain limits. Preferably, the flexible traction element comprises at least partially nylon or another synthetic material (and particularly nylon fibers), and / or metal (and particularly metal fibers or threads or synthetic fibers or threads), and / or natural fibers (such as cotton, linen, or the like). Flexible traction elements are particularly constructed as ropes, belts, lines, rubber bands, and / or chains.

[0013] The transmission element can be configured as a multi-piece unit. At least one element can be configured as or include a rigid rod.

[0014] The radiographic gripping device according to the invention has several advantages. The force direction unit allows the actuating force from the input (traction member) used to actuate the locking device to be directly transmitted to the locking device, and the locking device is actuated (specifically) using the input (input) operating force. The risks of the following are minimized or even completely eliminated, particularly when displacing the patient, where the locking device may be inoperable or may only be operable with a long and / or undefined actuation stroke.

[0015] For controlled actuation of the locking device, the force direction unit particularly advantageously allows the actuating force to be transmitted along any desired location or part of the transmitting element, especially the tension member. The force is deflected and / or directed in the desired direction by the force direction unit (or blocking unit). The tension member configured as a rope cannot be pulled out of the guide path. This prevents unintentional slack in the flexible tension member. This results in a substantially defined actuation stroke.

[0016] The flexible traction element or transmission element can be positioned at a considerable horizontal distance from the locking device, particularly at a distance greater than the user's arm span. Even with a long horizontal guide for the flexible traction element, i.e., especially at a given considerable distance from the pivot axis, the proportion of easily introduced traction or actuation stroke that does not contribute to the actuation locking mechanism is minimized.

[0017] Even when the flexible tension member is slack, and in the case of multiple tension members and / or actuating members, a defined actuation stroke can be set (independent of the actuation position along the tension member). In any case, it is not necessary to radially tighten the slack span after the actuation point (or further away from the pivot point) before applying the operating force.

[0018] The force direction unit (or blocking unit) causes at least one local locking movement in at least one direction. If the actuation point is located further inward than radially in the force direction unit, this prevents a portion of the flexible tension member from moving inward. This results in direct actuation when the locking device is actuated, eliminating the need to tighten, for example, a slack section of the flexible tension member before actual actuation of the locking device, moving it from radially outward to inward. This enhances operational reliability and safety.

[0019] The positions of the flexible traction element and the actuation component used for actuation remain essentially unchanged, including during repetitive actuation. This significantly facilitates the work of nurses or operators and improves patient comfort. Intuitive operation is possible because the actuation component can be anticipated and / or positioned in the same (substantially) identical location at all times.

[0020] Overall, the operability of the radiographic gripper, particularly the operability of the support arm, has been improved. The reliability of the actuation mechanism has also been significantly improved.

[0021] The precise positioning of the transmission elements and flexible tensioning components protects them from excessive contamination. Advantageously, the actuating components are gripped in the same location. This particularly aids in and promotes hygiene of the radiographic gripping device. Furthermore, the actuating mechanism is primarily easier to operate and use.

[0022] It includes at least one force direction unit (configured as a blocking unit). The force direction unit allows the operating force input for actuating the locking device to be directly transmitted to the locking device, and actuates the locking device entirely (almost) using the operating force and actuation stroke. The force direction unit transmits the operating force applied to the actuating member in a preferred direction. This means that the transmission element moves in the (opposite) preferred direction. In the case where multiple actuating members are connected in series at different locations and one actuating member in the middle (between the ends) is actuated, the force direction unit then causes the force to be transmitted essentially in only one direction. The movement of the transmission element (essentially) occurs in one direction. Movement in the opposite direction is (to a large extent) prevented. This reduces the required actuation stroke because the force direction unit specifically orients the direction and stroke of the force applied for actuating the locking device, effectively turning it to the desired direction.

[0023] When properly installed or ready for use, the axis of rotation of the support arm is oriented at least substantially vertically, substantially approximately vertically, or (almost or entirely) vertically or horizontally. The mounting device is preferably configured as a fixed bracket, specifically attached to, for example, the ceiling of a radiology room. The mounting device can also be specifically configured as a wall mount supported, for example, on a substantially vertical room wall.

[0024] The gripping device is specifically configured to include a gripping handle. The gripping device (or gripping handle) is particularly height-adjustable and therefore suitable for both taller and shorter individuals. Preferably, the height of the gripping device or at least one gripping handle is adjustable by at least 100 mm, particularly 200 mm or 300 mm, and for example, 500 mm, or 1 meter or more.

[0025] The support element or its bottom surface is preferably positioned at a height of approximately 2000 mm, or 2250 mm or higher. In particular, the adjustable gripping device can preferably be positioned at a height of 2000 mm or higher. A higher height provides greater headroom.

[0026] The mounting device can also be directly mounted on the radiological equipment and / or specifically integrated therein and / or attached to it. In this or other cases, the orientation of the rotation axis of the support arm can be adjusted by an adapter. Alternatively, the actuation device can be attached to a wall or floor, or otherwise mounted on the floor or ground.

[0027] The support arm is at least disposed and / or placed to, and preferably securely, preferably rotatably, and particularly at least pivotally disposed and / or placed to, the fixing device of the radiographic gripping device. The transmission element, particularly at least partially, moves substantially axially along or adjacent to the axis of rotation when the actuation mechanism is actuated. Preferably, the transmission element moves at least partially centered via a shaft of the support arm.

[0028] The transmission element is preferably made of a non-magnetic and / or non-conductive material. This avoids the antenna effect by means of the transmission element. This is particularly suitable for passage areas through shafts, and especially for passages through shielding devices and into or within adjacent areas.

[0029] Shafts and / or load-bearing members are preferably at least partially and / or partially constructed as (circumferentially closed) tube segments along their respective longitudinal axes, exhibiting at least partially and / or partially annular and / or elliptical and / or square cross-sections. These cross-sections can be, in particular, circular, triangular, quadrilateral, or polygonal. Similarly, shafts and / or load-bearing members can at least partially and / or partially be constructed as open U-shaped and / or V-shaped profiles. The partial construction as tube segments and / or open profiles provides a very robust and torsional-resistant structure. It allows for good force introduction and transmission, as well as a simple and stable structure. At least at the fixing point, the shaft is constructed as circular at least in the region of its rotatable support (or across the main portion of its length, or along its entire length).

[0030] Shafts and / or load-bearing components are particularly preferably made of stainless steel, especially "VA steel" or another stainless steel alloy. The material surface is specifically designed to be uncoated. Therefore, spalling and / or flaking and / or wear due to mechanical loads and stress can be prevented. Envisionable contamination is minimized and / or never occurs due to the hardened or solidified surface and the elimination of breakage.

[0031] The radiographic gripper is preferably designed to withstand a load of at least 1350 N, 1500 N, 1700 N, 2000 N, or 3000 N in the direction of gravity. In heavy-duty configurations, the radiographic gripper is preferably designed to withstand a load of up to 5000 N or more.

[0032] Radiographic grippers are specifically designed to support load moments of at least 5.5 kNm or at least 6.5 kNm, or at least 10.0 kNm or even higher under heavy loads. Radiographic grippers can also be preferably configured to support lower or higher forces and / or load moments. This depends primarily on the intended load. In cases where the primary or only purpose is to move children or very small or very light individuals, load limits can be configured to be quite low. For specialized radiographic systems used on highly overweight individuals, radiographic grippers can be configured for considerably higher loads.

[0033] Particularly advantageously, the actuation mechanism of the radiographic gripping device is operated by at least two actuating members. The actuating members can operate, at least partially, independently of each other; that is, the locking device can be actuated by at least one actuating member alone. In a simple case, at least a portion or segment of the transmission element can be formed of a cable or wire, etc. At least one actuating member can particularly preferably be configured as or include shaped elements such as buttons and / or knobs and / or handles. Alternatively, the actuating member can be formed by a cable loop and / or cable end. Other geometries or bodies are also conceivable.

[0034] Three, four, five, or more actuating elements may be provided. Advantageously, the actuating elements may be at least partially disposed and / or constructed on at least one transmission element. Advantageously, the actuating elements enable comfortable and particularly safe operation. The operator can then, for example, pull the actuating element, thereby pulling the transmission element, for example, constructed as a cable, to release the locking device, and simultaneously pivot the support arm to the desired position.

[0035] Furthermore, in particular, at least one actuating member is disposed on the carrier of the bearing arm near the gripping device. This advantageously enables immediate operation by means of the gripping device. Therefore, the comfort of actuation is greatly improved in particular.

[0036] Another actuating component can also be configured as an electrical sensor and / or switch. In this case, the locking device is electrically actuated via an actuation mechanism. In this case, the transmission element is preferably configured as and / or includes a conductive cable. The actuator used is preferably not motor-driven or electrically driven, but driven by mechanical means.

[0037] Preferably, the actuation mechanism can be operated by at least two actuating members independent of each other. In particular, more than two actuating members are provided, through which the actuation mechanism can be actuated individually. The at least two actuating members can be respectively arranged in series and / or in parallel on the transmission element or connected to the transmission element in series and / or in parallel. The actuating members can be oriented such that actuation from different positions on the support arm is advantageously feasible. Similarly, the actuating members can be formed from the transmission element itself. For this purpose, the actuating members can be formed from a section approximately horizontal to the transmission element.

[0038] In at least one advantageous embodiment, the actuation mechanism includes at least two force-directing units (each configured as a blocking unit). In particular, it may include three, four, five, or more force-directing units. Advantageously, each actuating member includes at least one force-directing unit. Furthermore, in the case of long tension members or transmission elements, providing one, two, or more force-directing units may be advantageous to ensure the reliability of the actuation locking device. Advantageously, multiple force-directing units prevent or compensate for accidental slack or extension of the transmission element, and particularly the tension member. This enables and further improves the reliability of actuation with a substantially defined actuation stroke.

[0039] Preferably, the actuation stroke of the traction member is less than twice the diameter of the actuating member. Advantageously, the actuation stroke can be at least four, eight, or even twenty times the diameter of the actuating member.

[0040] In at least one advantageous embodiment, the actuation stroke at at least one actuating member substantially corresponds to the minimum stroke required by the actuation mechanism of the actuation locking device. This is the minimum actuation stroke. Preferably, the actuation stroke at at least one other actuating member is no more than five times, and particularly three times, or two times, the minimum actuation stroke.

[0041] The stroke length or (minimum) actuation stroke of the transmission element is preferably less than 100 mm, and particularly between 50 mm and 5 mm, and preferably about 15 mm. Furthermore, the actuation stroke can be up to 30 mm, 60 mm, or even up to 120 mm or more. Advantageously, a short, defined actuation stroke improves the operation of the radiographic gripping device. The user no longer needs to assume an undefined actuation stroke, even during repetitive operations. Therefore, accidents can also be advantageously prevented.

[0042] Preferably, the change in actuation stroke required for actuation between at least two or almost all or all different actuating components is less than 150 mm or 100 mm, preferably less than 50 mm, and particularly preferably less than 25 mm.

[0043] Preferably, the variation in actuation stroke required for actuation between at least two or almost all or all different actuating components is less than 300% or 200%, preferably less than 100%, and particularly preferably less than 50% or 25%. Shorter (absolute) actuation strokes may show a larger percentage deviation than longer actuation strokes.

[0044] In a particular configuration, the actuation stroke along the first actuating member is 15 mm, and it can be at most 10 mm longer or shorter depending on the configuration and arrangement. Then, the deviation from the actuation stroke of the second actuating member, or from the actuation stroke of (almost) all other actuating members, is particularly less than 75 mm or 50 mm, and preferably less than 20 mm or preferably less than 200% of the actuation stroke. However, if the normal actuation stroke is already 100 mm, the deviation from the actuation stroke of the second actuating member is particularly less than 100 mm and preferably less than 50 mm.

[0045] Advantageously, the force direction unit includes at least one retaining portion or stop. The term "stop" is used herein as a synonym for the term "retaining portion," and therefore can be consistently replaced in this application. Conversely, in this application, the term "stop" can be replaced by the term "retaining portion." The term "stop" will be used hereinafter. The stop is particularly disposed on the bearing arm. Preferably, the traction member is at least partially placed, particularly at least guided, and / or even fixed to the stop. The stop, or at least one stop, is particularly disposed at least on the shaft and / or particularly preferably on the bearing member of the bearing arm. In particular, the stop includes, surrounds, guides, and / or guides the flexible traction member. The stop can also deflect the flexible traction member. In this case, a separate guiding member is not required to guide the flexible traction member. Preferably, the stop exhibits a smooth profile design without any corners or edges for guidance. Furthermore, the stop can be supported on or disposed on surrounding components or objects. Advantageously, the stop can transmit the introduced operating force almost directly to the locking device.

[0046] In at least one advantageous configuration, the stop exhibits a profile that extends with a radial distance gradually increasing from the pivot axis. Advantageously, the extended profile design enables the guiding and deflection of the flexible tension member. Furthermore, it allows for good force reversal, enabling the operating force to act directly on the locking device.

[0047] Preferably, at least one stop is located at a pivot axis at a radial distance corresponding to at least 20% of the maximum radial length of the support arm. Advantageously, at least one stop is located at a radial distance corresponding to at least 30%, 50%, 70%, or a greater proportion of the maximum length of the support arm. In particular, stops are located at the radial ends of the support arm. Advantageously, at least one stop is located radially outward of the fixing device. Advantageously, the actuating member is located near the gripping device. Advantageously, actuation of the radial gripping device is therefore particularly comfortable. Furthermore, it is advantageously feasible to pivot the support arm in a radial position, which presents a particularly long lever arm relative to the pivot axis, so that the user only needs to apply a small force.

[0048] Particularly preferably, at least one actuating member capable of actuating the locking device is disposed and / or attached to the radially outer side of the fixing device. Advantageously, the actuating member is disposed particularly close to at least one gripping device. The gripping device may preferably be disposed near or at the radial end, i.e., given a large bearing arm radius. Advantageously, actuation can be performed from the vicinity of the gripping device.

[0049] Preferably, the force direction unit includes at least one abutment. The abutment is preferably attached to or disposed on the flexible tension member. Particularly advantageously, the abutment at least partially surrounds or encloses the flexible tension member. Preferably, the abutment is used to support and, in particular, to tension the flexible tension member. Preferably, this allows for the realization of a substantially defined position for the tension member and, in particular, the actuating member. The abutment advantageously functions as a “cable stop,” at least partially biasing the flexible tension member, specifically configured as a cable, to lock its movement in unintended directions. Therefore, the operating force can be transmitted substantially directly to the locking device. Thus, the abutment can also be referred to as a locking member because it impedes movement of the flexible tension member in one direction. Therefore, the term “locking member” is used synonymously with the term “abutment,” and thus it can be used interchangeably in this application. Conversely, in this application, the term “locking member” can also be replaced by the term “abutment.” The term “locking member” will be used hereinafter.

[0050] The locking element is specifically (at least partially in a force-transmitting and / or form-fitting manner) attached to, received from, or disposed on the tension member. In at least one advantageous embodiment, the locking element is connected to the tension member via at least one contact segment and / or annular segment of a flexible tension member and / or threaded unit, and is particularly received on the tension member.

[0051] The locking element may also be formed from a (partial) protrusion of the tension member. The locking element may be formed, for example, as a contact or segment enlargement, wherein the protrusion configured as rigid or resilient is received in or on the flexible tension member.

[0052] Particularly preferably, the locking member is attached to the tension member, and the movement of the locking member relative to the tension member is restricted in at least one direction.

[0053] Advantageously, the locking member includes at least one at least partially closed receiving unit. The pulling member is preferably disposed on the lockable receiving unit. Advantageously, this allows for a permanent and stable connection between the locking member and the flexible pulling member. The locking member can be locked onto the pulling member in particular. For this purpose, the receiving unit, and especially the threaded unit, can preferably include at least one fixing screw by means of which the pulling member can be at least partially locked onto the locking member. The position of the locking member on the flexible pulling member is preferably freely adjustable. Preferably, the connection is detachable, and all components are replaceable. This also allows for the achievement of particularly high hygiene requirements. Advantageously, the locking member can be at least partially supported on the stop member. Preferably, the stop member can receive the locking member. The locking member is particularly matched to the contour and profile design of the stop member. Thus, the locking member can exhibit a tapered profile design that the stop member can receive. The locking member is particularly configured to be rotationally symmetrical so that the locking member automatically centers on the stop member. Advantageously, at least during the introduction of the operating force, the locking element is supported on the stop. Advantageously, the pulling member thus directly transmits the operating force introduced by the flexible pulling member to the locking device. The use of the locking element particularly preferably ensures the safe and repeatable function of the force direction unit and the actuation mechanism.

[0054] In all feasible advantageous configurations, the actuation mechanism may include at least two transmission elements. Preferably, the transmission elements are connected by at least one, particularly detachable, engagement unit. The engagement unit may extend the transmission element, or it may be capable of being changed among various transmission elements. Thus, a force-transmitting connection can be advantageously established via the engagement unit. The engagement unit can also be used to connect the transmission component, configured as a rod member, to a flexible tension member.

[0055] Preferably, the engagement unit may include at least one sleeve portion. Advantageously, the engagement unit also includes at least one threaded unit. Advantageously, the transmission element is specifically configured as a flexible pull member. Preferably, the sleeve portion and the threaded unit at least partially surround the transmission element. The threaded unit may specifically be configured as a fixing screw through which the transmission element passes at least partially. In particular, the flexible pull member is configured with at least one contact portion. Advantageously, the contact portion is located on the engagement unit and preferably on the sleeve portion and / or the threaded unit, where the pull member is positioned. The engagement unit is configured to connect multiple transmission elements for quick replacement. Preferably, no tools are required to open or close the engagement unit.

[0056] In at least one advantageous embodiment, the transmission element passes through at least one hollow section of the shaft.

[0057] Because the transfer element passes through the hollow section of the shaft, the radiographic gripper as a whole, and especially the support arm, is particularly compact and space-saving. The transfer element does not need to rotate about the axis of rotation of the support arm as it pivots. Therefore, passing through magnetic shielding becomes particularly easy. No slots, elongated holes, or linear openings are required to allow the transfer element to pivotally pass through shielding devices (if any) or partition walls. Sealing or shielding is quite easy and simple.

[0058] In cases where conceivable radiographic gripping devices pass through suspended ceilings, such as those with magnetic shielding (Faraday boxes), 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 at a minimum cross-section. In any case, sealing the holes in the shielding device is neither particularly complex nor, optionally, entirely unnecessary.

[0059] Preferably, the locking device of the radiographic gripper establishes a force-fit and / or form-fit connection between the support arm and the fixing device. The locking device can be specifically configured in a force-fit manner as friction braking and / or band braking, etc., wherein the locking position is implemented in a force-fit manner due to the interaction of the friction liner and / or the band on the mounting portion. Preferably, the friction liner is mounted or constructed (e.g., integrally) on the mounting portion and on the support arm. In this case, the support arm is non-rotatably clamped or locked in the locked position. Alternatively, the locking position can be implemented in a force-fit manner, for example by means of a magnetic locking device. In this embodiment, the locking device of the support arm is held in the desired locking position, for example, directly by magnetic force, or the fixing member is transferred to and / or held in the locking position by magnetic force. In these cases, any desired locking position is feasible at any desired angular position.

[0060] However, particularly preferably, the locking device can be designed as a form-fit. In this case, the angular position is locked by means of interlocking form-fit members. The form-fit connection can be constructed by interlocking members or by meshing or other form-fit profile designs.

[0061] Advantageously, the locking device includes at least one fixing member for locking the locking device. Preferably, the transmission element can be switched from a locked position to a rotating position, in which the angular position of the support arm can be changed relative to the fixing device. In particular, the support arm can rotate freely in the rotating position or can pivot within a predetermined angular range. Particularly preferably, grid points are provided.

[0062] Preferably, by actuating the actuating member, the movement of the transmission element is locked by a locking member, which is located at a stop at a greater radial distance than the actuating member, thereby ensuring that the operating force acts primarily on the fixed member of the locking device. Thus, a simple blocking unit is achieved.

[0063] The transmission element is connected to the stationary member indirectly and / or directly, by force-transmitting and / or form-fitting means. Alternatively, the transmission element may be configured to include, or at least comprise, an electrical conductor and / or an actuator. In this and other cases, at least one additional actuator or actuation device may be included. For example, a positioning motor may be provided by means of which the stationary member can be moved from a locked position to a rotary position (and vice versa).

[0064] The radiographic gripper can be pivoted and / or rotated by at least one actuating device, particularly by a motor and preferably by an electric motor. In this case, the radiographic gripper can be pivoted, in particular, by a remote control device provided with a wireless or wired connection to the actuating device. In a preferred variant, the radiographic gripper can be pivoted solely by the actuating device when it is locked in a secure locked position. Such a safety function can preferably be overrided by at least one safety switch. Actuating such a switch allows the radiographic gripper to pivot even when it is not in the locked position.

[0065] In all configurations, the locking device preferably includes at least one retaining member that engages with at least one of a plurality of locking elements. The retaining member is specifically configured and / or disposed on the fixing device to enable multiple locking positions for fixing.

[0066] The locking element is specifically configured as a recess, and preferably as a hole or countersunk hole. At least one fixing member is specifically configured as an engaging member that allows or establishes a form-fit connection with the fixing device. At least one engaging member is advantageously configured as a bolt that engages with a form-fitting hole in the fixing device in the locked position.

[0067] The locking element and the fixing member preferably interact to achieve a locked position. When the locking element and the fixing member are engaged, rotation is prevented, and when disengaged, the support arm can pivot. Particularly preferably, the locking element is configured as a recess, and the fixing member includes bolts, etc., for insertion into the recess. Reverse operation is also conceivable, in which the fixing member, for example, shows a recess, and a bolt-shaped locking element engages therein in the locked position. The fixing member and the locking element can also be configured as adapted pre-formed components that interlock in a form-fit (and / or force-fit) manner. The fixing member, as a component of the locking device, is preferably disposed on the support arm. Multiple suitable locking elements (recesses) are preferably configured and / or disposed on the fixing device.

[0068] Alternatively, bolts and recesses may be matched precisely opposite to the bearing arms and fixing devices if it appears necessary or desired due to the structure.

[0069] The construction of a locking device using at least one bolt as a fixing member or a connecting part engaged in a hole in the bore circle has the advantages of being particularly simple and inexpensive to manufacture. Such a structure is very robust. The form-fit connection helps to absorb lateral forces and torques, and facilitates the reliable fixing of the support arm in the locked position. The mechanism can be centered about the axis of rotation of the support arm and is space-saving.

[0070] Particularly preferably, multiple recesses, and especially holes and / or countersunk holes, are distributed on the circumference of the disc or, for example, a ring, particularly as a (periodic, uniform) circle of holes on the fixing device. The pivoting bearing arm allows the bolts of the bearing arm to be secured in various angular positions because the bolts engage in one of the holes distributed on the circumference of the circle of holes. In this way, the bearing arm can be secured in a desired locking position.

[0071] Particularly preferably, the holes are equidistant from each other at intervals of preferably 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 at uneven intervals on the circumference. For example, multiple recesses can be provided on a small circumferential segment, while only a few possible locking positions are provided on another corresponding circumferential segment.

[0072] In an advantageous construction variation, multiple recesses (approximately circular) are arranged throughout a diameter larger than the shaft's diameter. Particularly preferably, the recesses are arranged throughout a circle with a diameter 1.5 to 2 times larger than the shaft's (outer) diameter. This is advantageous for facilitating bolting within the recesses. Locking devices with recesses arranged in a circle and fixing members constructed as bolts, cones, frustocones, etc., are particularly easily accessible. This is primarily an advantage in maintenance and repair work. Therefore, the locking device can preferably be positioned close to the shaft.

[0073] Preferably, the radiographic gripping device includes at least one biasing device that biases the engaging member into a locked position. The biasing device is particularly preferably such that the locking device is regularly or (almost) always in the locked position unless the actuating mechanism places it in a rotational position. Biasing by at least one biasing spring is particularly feasible, which pushes the bolt, acting as a fixing member, into a hole in the corresponding locking position at a suitable angular position. The biasing device may preferably be configured as or at least include a compression spring, a helical spring, a coil spring, a leaf spring, or other elastic member. The elastic properties of another component may also be utilized to bias the fixing member. The biasing device may particularly be configured as a magnetic or pneumatic mechanism.

[0074] In the case of rotational movement, when the fixing member engages in the recess during rotation, the biasing device preferably automatically locks the fixing member into place. In this way, the bearing arm is advantageously biased regularly or always to a fixed angular position.

[0075] Because the fixed component is biased in the locked position, the support arm of the radiographic gripper is non-rotatably locked in its angular or locked position. A person can safely pull themselves up and / or brace themselves against the gripper of the radiographic device, thus enabling the radiographic gripper to be used non-rotatably for person relocation. In the event of any impact and / or sudden movement of any part of the radiographic gripper, the angular position of the support arm is reliably locked and cannot even be moved by impact.

[0076] Preferably, the shaft member exhibits a shielding or covering device at least along the middle range of its longitudinal axis, extending particularly transversely and preferably perpendicularly to the shaft member. This shielding device is specifically designed to shield or seal a passage through at least one intermediate top plate and / or magnetic shield. A magnetic shield is particularly provided in and / or on the intermediate top plate, which adequately shields radiation emitted from the operating radiological equipment. The shielding device particularly encloses this magnetic shield to enable safe and reliable operation of the radiological equipment. For this purpose, suitable material for shielding can be specifically machined and / or incorporated into and / or onto the shielding device. The connection between the shielding device and at least one intermediate top plate allows it to be adapted to additionally support the shaft member. This improves system rigidity. Multiple shielding devices may be provided on the shaft member.

[0077] Constructions without shielding devices are also possible. This variant is particularly preferred if the radiographic gripping device is intended for use in a room without any intermediate ceiling and / or on a wall. Additional shielding devices can be provided, which specifically completely cover the fixing device and locking mechanism.

[0078] The actuating element may be specifically provided with an additional protective sleeve that protects the transmission element and actuating mechanism from contamination primarily from the user's hands. The protective sleeve is particularly preferably constructed in a cylindrical and / or annular shape. Other constructions are also conceivable. Preferably, the sleeve can simply surround the transmission element. In the case where an adjacent actuating element is constructed as a knob, it can easily support the sleeve, allowing the sleeve to be positioned by gravity. The sleeve is particularly preferably made of a material or combination of materials exhibiting an antimicrobial finish and being easy to clean. Advantageously, the material exhibits a smooth surface, thus preventing the accumulation of dirt. Preferably, the protective sleeve has a length greater than 5 mm, particularly greater than 10 mm. Preferably, the protective sleeve is constructed to a length between 5 mm and 100 mm, particularly between 10 mm and 60 mm.

[0079] In a particularly advantageous variant, the transmission element extends from the interior of the shaft to its radially outward region. The transmission element then (particularly space-efficiently) passes through the shaft. Therefore, the transmission element does not need to pass through an opening in the intermediate top plate adjacent to the shaft, which must be sealed separately. Thus, the required opening is limited to the shaft and its cross-section. When the support arm pivots, the transmission element does not need to rotate about the shaft. The transmission element pivots substantially centrally with respect to the shaft.

[0080] Particularly preferably, the transmission element is positioned and / or guided at least one-quarter or at least half the length of the carrier, particularly at least two-thirds of the length of the carrier, and / or advantageously at least three-quarters of the length of the carrier. This allows the actuating member to be positioned, particularly preferably, near the gripping device. An actuation mechanism may optionally be provided for patient actuation. In any case, the operator can grasp radially outward to pull the actuating member and release the locking device while simultaneously guiding and pivoting the carrier of the carrier arm.

[0081] Preferably, the transmission element passes through the shaft via at least one guide unit inside 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 shaft via guide units configured as guide rails. The guide rails are particularly configured as tubular segments exhibiting circular and / or elliptical and / or polygonal cross-sections, particularly showing three, four, five, and / or more angles.

[0082] Alternatively, the guide unit can be configured with an open profile having a U-shaped and / or V-shaped cross-section. The guide unit particularly preferably guides the transmission element along the axial direction for at least one segment inside the shaft. The guide unit allows the transmission element to pass radially outward from the inside at least once, and / or radially inward from the outside at least once.

[0083] The guiding unit can be a single piece and / or multiple pieces. It can be composed of a variety of materials. The side through which the transmission element passes may have a special friction-inhibiting surface and / or may be provided with a friction-inhibiting coating or layer (such as graphite) to facilitate and improve the mobility of the transmission element. In addition, a self-lubricating coating with the aid of oil and / or grease may be provided.

[0084] The guide unit is advantageously made of plastic, providing a particularly smooth surface over which the transmission element can glide. The other side and / or location of the guide unit may include a material particularly suitable for suspending or otherwise mounting the guide unit inside the shaft, such as steel.

[0085] The construction of the traction member, or the transmission element of a cable, chain, or belt, offers the advantage that a button and / or knob, serving as the actuating element, can be attached to its end, allowing the actuation mechanism to be operated via this button and / or knob. The actuation mechanism can be operated simply and directly. During operation, the flexible traction member can easily compensate for minor changes in the operator's hand position, thereby moving the actuating member along the movement of the patient's and / or operator's hand. The direction and / or orientation and / or local advance of the traction member can be variably set for the user's benefit, allowing the cable end to also be directly used as the actuating element.

[0086] The construction of the transmission element as a mechanical tension member provides a further advantage, namely that at least two actuating members can be easily connected in series and / or in parallel with the transmission element. Therefore, the actuation mechanism can advantageously be actuated by at least two actuating members. The flexible tension member of the transmission element can, or is equally preferably, mounted along the support arm, particularly along the support member. The transmission element itself can serve as an actuating member. The various actuating members can be radially spaced from each other so that actuation can be achieved from various locations along the support arm, and particularly along the support member.

[0087] Advantageously, the transmission element is deflected and / or guided by at least one guide roller disposed on the outside of the shaft and / or at least one guide roller disposed on the inside of the shaft. The deflection roller is preferably disposed on the shaft of the support arm. This allows the flexible traction element to be advantageously guided to at least one locking device. The movement of the transmission element can be deflected simply and directly in the desired direction. The movement of the deflection roller when the actuation mechanism is actuated allows for particularly low-friction guidance of the direction of movement of the transmission element. Particularly preferably, at least one deflection roller is disposed beside the shaft through which the transmission element passes radially outward. The deflection roller may also be disposed on the support arm, guiding the flexible traction element of the transmission element along the support arm.

[0088] Particularly preferably, the transmission element is deflected by at least one deflecting sleeve. The deflecting sleeve is specifically configured as a tubular section, preferably exhibiting a circular and / or elliptical and / or polygonal cross-section. This allows for efficient adaptation to the direction of action of the transmission element, particularly preferably including an inner side with a small radius. The deflecting sleeve can also be configured with a profile that is at least partially open, having a U-shaped and / or V-shaped cross-section. Guides can be particularly used to change the orientation of the transmission element inside a hollow shaft and during entry into and exit from the shaft.

[0089] In a particularly preferred configuration, the transmission element extends axially through the shaft at least downwards. This axial extension of the transmission element through the shaft advantageously allows for deflection of the flexible tension member. Therefore, the transmission element can be centered off the shaft below the axis of rotation of the bearing arm, thereby allowing the actuation mechanism to operate substantially centrally.

[0090] The deflection sleeve is advantageously capable of deflecting transmission elements, including in cases of small radii and in places where deflection rollers cannot be installed.

[0091] Advantageously, the radiographic gripping device includes at least one limiting device for restricting the rotation angle. The rotation angle limiting device can be particularly preferably configured, for example, to be disposed and / or attached to a fixing device or disposed and / or fastened to a fixing device as a stop. The limiting device for restricting the rotation angle is used to particularly preferably limit the rotation angle of the support arm to a total rotation angle, for example, 270°, 180°, or 90°. The specific angle depends on the particular situation and specific conditions. Therefore, the rotation angle can be limited to a smaller total angle, depending on the setup in the machine room and / or the spacing and number of feasible locking positions. It is also feasible to construct the radiographic gripping device without any limiting device.

[0092] Particularly preferably, the rotation angle limiting device includes a buffer component that allows for a soft, cushioned limiting stop. The buffer component is preferably configured as a rubber pad and / or a gas spring and / or a rubber handle. This allows the radiographic gripper to be specifically designed or integrated into the radiation room to accommodate the requirements and needs of the radiographic system, patient, or operator, as well as the room's geometry. Preferably, the locking device may have at least one stop for this purpose. The limiting device may be specifically attached to the room wall. In this case, the limiting device is not integrated into the locking device. In this way, the working area of ​​the radiographic gripper is defined.

[0093] In a particularly advantageous variant, the radiographic gripping device includes a buffer device that, in particular, surrounds the radiographic gripping device over a large area and / or in particular completely, protecting it from (mostly or almost entirely) impacts and collisions with other devices in the radiation chamber during pivoting.

[0094] This type of buffer unit is particularly suitable for protecting radiological gripping devices and / or other components of radiological systems from damage during operation. The buffer unit is particularly preferably characterized by an (outer) diameter of at least 100 or 150 mm, especially 250 mm and / or 350 mm. However, smaller diameters are also conceivable depending on the available installation space and the conditions of the radiation chamber. The buffer unit is specifically constructed on and / or completely surrounds the support member of the support arm. The buffer unit can also particularly be at least partially surrounding the shaft of the support arm. Advantageously, this provides effective protection against damage.

[0095] Advantageously, the buffer unit comprises an elastic material, preferably rubber and / or plastic. The buffer components may also particularly preferably comprise a variety of materials. The buffer unit may also particularly preferably comprise reinforcing members made of rigid plastic or metal materials.

[0096] Particularly advantageously, the radiographic gripping device includes at least one receiving rail having at least one hook point or hook portion, into which at least one gripping device can hook. Advantageously, the receiving rail extends over at least a majority of the radial length of the support arm. At least one receiving rail is constructed along the support arm. The receiving rail can be constructed to be bending rigid, thereby extending the radial length of the support arm by at least 25%, 50%, 75%, or even up to 100%. However, the length of the receiving rail can be significantly shorter than the length of the support arm. In particular, multiple receiving rails can be arranged along the support member. This makes the construction particularly torsional robust, providing high resistance to moment under loads of normal and / or lateral forces and / or bending moments.

[0097] The gripping device specifically includes at least one hook member for hooking into a receiving rail. It is specifically configured, or specifically includes at least one hook member and is specifically a spring hook (hook) or an open hook. In the case of an open hook member, the dimensions of the hook's legs are preferably designed to achieve a very large holding angle of 45° or more.

[0098] 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. Therefore, stable support is advantageously achieved in almost any conceivable location. Preferably, the hook member configured with an open hook can only be removed from the receiving rail at a pivot angle exceeding 30° and preferably exceeding 45° and particularly preferably exceeding 60° relative to the vertical. The short leg can then be pushed upwards, and the gripping device with the open hook can be removed. At a suitable angle, the open hook of the gripping device can be re-inserted into another position on the receiving rail or onto another receiving rail to allow the gripping device to be used in another position.

[0099] In particular, multiple hook points or hook portions are provided and / or constructed along the receiving guide rail. Particularly preferably, the receiving guide rail is connected to the support arm at both ends.

[0100] In particular, at least two receiving rails are provided along the entire length of the support arm, thereby allowing the gripping device to access every point within the primarily circular operating range.

[0101] To advantageously support the gripping device, at least one additional support hook can be provided, for example at the end of the support arm, or (when not in use) at the various longitudinal sections used to support the gripping device. Because the gripping device is hooked into the support hook, it will not become an obstacle during the pivoting movement of the support arm. This particularly advantageously achieves simple, safe, and easily adjustable protection for the gripping device.

[0102] The hook point or hook area can provide a locking position for the gripping device. The function of the receiving rail is not limited to the hooking device. It can also be used specifically to grip infusion bags and / or infusion stands. Other functions are also conceivable. A standalone infusion stand is also conceivable.

[0103] The receiving rails are particularly preferably made of stainless steel, especially "VA steel" or another stainless steel alloy. In particular, the material surface is configured to be uncoated and to produce little or no wear due to mechanical abrasion. Alternatively, the receiving rails may be constructed transversely to or inclined to the support arm and, in particular, the support member. Two or more receiving rails may also be provided on at least one support arm. The receiving rails are advantageously configured to allow the gripping device to move between multiple different hook points or hook locations without disengaging the entire gripping device from the receiving rails. Particularly preferably, two receiving rails are constructed along the entire radial length of the support arm. Disengagement is then only necessary when the gripping device must, for example, be transferred from one receiving rail to another. Three or more receiving rails are also conceivable.

[0104] The hook point is preferably formed by a shaped member, and the annular member of the gripping device advantageously engages in the shaped member under tensile load. The hook point or hooking area may be formed by local "valleys" in the receiving guide and constrained by local "hills" therebetween. Therefore, the position of the gripping device can be changed along the support arm without releasing the form-fit connection between the receiving guide and the gripping device. This allows for simple and quick adjustment and modification of the gripping device's position between multiple locations. For this purpose, the gripping device is simply pushed further into the next hook point or lifted over the next "hill." The gripping device therefore does not require complex disassembly to prevent it from falling when changing the hook position. The possibility of injury to the user is minimized.

[0105] Particularly advantageously, the gripping device includes a belt unit. The belt unit is advantageously positioned between the hook member and the gripping member. The belt unit is primarily used to facilitate the patient's sitting up and movement. For this purpose, the length of the belt member, which is specifically motor-assisted, can be modified according to the user's requirements and conditions.

[0106] Particularly preferably, when ready for use, the belt unit is supported to rotate about an axis oriented transversely to the horizontal direction. Particularly preferably, the belt unit is supported to allow for easy sliding, so that when the gripping device or its gripping handle rotates, the belt unit rotates about its support point so as not to twist the belt itself, or only to twist it minimally. Preferably, when the gripping device pivots, the rotation of the belt unit about its support point is significantly greater than the rotation of the belt torsion.

[0107] The belt is preferably formed of a wide fabric strip. Advantageously, when used as intended, the belt does not twist at all, or only twists very little. Adjusting the length is primarily for the purpose of advantageously adapting the length of the gripping device to the user and his / her position, so as to allow advantageous support and / or transfer in different positions.

[0108] The motor-assisted actuator with unit can be particularly preferably provided by a coil spring, or alternatively by an electric motor specially configured as a positioning motor. Control can be particularly advantageously provided by a control unit that can be operated and / or controlled directly on the gripping device or via remote control. Alternative configurations of motor-assisted actuators with pneumatic and / or hydraulic motors are also conceivable.

[0109] In all configurations, the patient can independently assist themselves in transfer or repositioning. Furthermore, the transfer unit is particularly advantageous in enabling the patient to lift themselves with the aid of a support unit or gripping hand, facilitating their transfer. Thus, the patient can be transferred using a transfer unit configured as a stretcher and / or chair and / or transfer cloth. Other types and embodiments of transfer units are also possible.

[0110] Advantageously, it also minimizes the need for support from nursing or radiology staff during transfers. Ideally, nurse assistance is virtually unnecessary. In this way, the risk of bacterial, viral, and germ transmission is minimized. The possibility of sexual harassment during transfers is significantly minimized. Loss of working time due to psychological stress or the spread of bacteria is significantly minimized. This primarily improves the operability and profitability of the radiology system.

[0111] Advantageously, the radiographic gripper is at least partially made of a material that is completely non-magnetizable or only difficult to magnetize and / or only slightly magnetizable. Operating radiographic equipment generates high-intensity magnetic fields. Therefore, metallic materials exhibiting specific molecular structures may be magnetized, potentially leading to interactions with the radiographic equipment. Thus, all parts and components of the radiographic gripper are preferably made only of slightly and particularly completely non-magnetizable materials, such as plastics and / or aluminum and / or stainless steel. However, advantageously, at least a large portion of the radiographic gripper is made of a material that is completely non-magnetizable or only difficult to magnetize. This allows for the elimination and / or at least minimization of magnetic interactions between the radiographic gripper and the radiographic equipment (and consequently, artifacts in the images). This is primarily for the safe and reliable operation of the radiographic equipment and the resulting high-quality images.

[0112] In at least one advantageous embodiment, at least one transmission element passes at least partially through the hollow section of the carrier. Advantageously, the force direction unit may also be at least partially disposed on the inside of the carrier. Thus, the tensioning member can be protected from contamination in a particularly hygienic manner.

[0113] Particularly preferably, the radiological system according to the invention includes at least one radiological device and at least one radiological gripping device.

[0114] Advantageously, the radiological system includes at least one patient placement area for performing examinations using radiological equipment, the placement area being at least partially located within the operating range of the radiological gripper. Preferably, the patient placement area is located in the center of the operating range of the radiological gripper, thereby allowing for efficient use of the operating range of the radiological gripper.

[0115] Other advantages and features of the present invention can be obtained from the embodiments described below with reference to the accompanying drawings.

[0116] The applicant reserves the right to claim separate protection for a birthing device gripper used with birthing devices, such as, in particular, birthing chairs or stools, birthing baths, or birthing beds, which include a fixing device for pivotally mounting at least one support arm, the support arm including at least one axle and at least one support member, wherein the axle of the support arm is pivotally mounted on the fixing device for pivoting the support arm. The birthing device gripper includes a locking device for locking the support arm in at least one locked position and an actuation mechanism for actuating the locking device, the actuation mechanism including at least one transmission element and at least one actuating member, wherein the transmission element is at least partially configured as a flexible traction member. The birthing device gripper includes at least one gripping device for direct attachment to the support arm, for example, providing a gripping mechanism for a woman in labor to, for example, sit up, move, or grip. The axle of the support arm is pivotally mounted on the fixing device to pivot the support arm. The actuation mechanism includes a force direction unit to selectively transmit an operating force introduced into the flexible traction member to actuate the locking device. The actuation mechanism particularly includes at least one transmission element passing through a hollow section of the axle. In certain embodiments, the delivery device gripper may include the features described herein with reference to a radiological gripper. Attached Figure Description

[0158] Figure 1 A view of a radiological system 100 according to the present invention is shown. The radiological gripper 1 is shown in cross-sectional view, while the radiological equipment 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 radiological gripper 1 includes a fixing device 2 that pivotally houses and supports a support arm 3. The support arm 3 includes a shaft 4 and a support member 5 pivotally fixed to the fixing device 2. The support arm 3 is pivotable about a rotation axis 4a or a pivot axis 4a.

[0159] The fixing device 2 is configured as a fixed bracket and fixedly mounted to the top plate (not shown) of the radiation chamber. The shielding device 18 is centrally mounted on the shaft 4 to shield the opening formed by the support arm 3 passing through the intermediate top plate of the magnetic shield. In the case where the radiological gripping device 1 does not pass through the intermediate top plate, the shielding device 18 is preferably configured to completely enclose the fixing device 2.

[0160] At hook point 24, a gripping device 9 is provided, which is formed by a gripper showing at least one hook member 35. The gripping device 9... Figure 8 This is specifically shown and described in the text.

[0161] The radiographic gripping device 9 is positioned near a radiographic 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 9 can pivot above the patient treatment table 26, making it easily accessible to the patient.

[0162] Along the support member 5, two receiving rails 23 are configured with a plurality of hook points 24 along the entire length 34 of the support member 5. A gripping device 9 is hooked at one of the hook points 24 of the receiving rails 23, which the patient can grip for support during displacement and positioning. An infusion bag 30 can be hooked into the hook points 24 of the receiving rails 23. The hook points 24 of the receiving rails 23 are configured as a "valley" between two "hills" in the contour of the receiving rails 23. Due to the geometry of the "valley," the tensile load applied to the gripping device 9 during normal use will shape-fit the gripping device 9 into the hook points 24. The gripping device 9 includes a belt unit 32, preferably mechanically spring-driven, the length of which is variablely adjustable. The gripping device 9 is received into the hook points 24 via at least one hook member 29. Additionally, the gripping device 9 can also be positioned on a support hook (not shown) so that it does not interfere when the support arm 3 is pivoted.

[0163] The receiving rail 23 is configured radially adjacent to the gripping knob, which serves as the actuating member 12, on the carrier member 5. Each receiving rail 23 includes multiple hook points 24. The hook points 24 are configured as "valleys" in the contour of the receiving rail 23. Among the multiple hook points 24, the gripping device 9, formed by a gripper and two hook members, hooks into the farthest hook point 24. The multiple "valleys" of the receiving rail 23 serving as hook points 24 are separated from each other by "hills" in the contour. The tensile load applied during normal use fixes the position of the annular ring of the gripping device 9 to the hook point 24. The gripping device 9 can easily push over the "hill" into another hook point 24 without having to remove the legs of the hook. This achieves a safe structure that presents load capacity. Actuating the actuating mechanism 8 allows the carrier arm 3, which is locked in the locked position 7 by the locking device 6, to be transferred to a rotational position opposite to the force of the biasing device 17. In the rotating position, the bearing arm 3 can pivot about the rotation axis 4a of the shaft 4.

[0164] The actuation mechanism 8 includes a total of three force transmission elements 11, all of which are configured as flexible pulling members 19, or more precisely, as pull ropes. Here, the first transmission element 11 is connected to the locking device 6. This first transmission element 11 is configured as a pull rope that is guided outward through the hollow section of the shaft 10, axially downward through the shaft 4, and radially directed towards and positioned on the support member 5. Here, another transmission element 11 is shown connected to the first transmission element via a coupling unit 206, and further extends radially outward along the support member 5. The second pulling member 19 is guided to extend horizontally along the support member 5 at the force direction unit 200. The flexible pulling member 19 is guided and deflected downward at the force direction unit 200. Two force direction units 200 are provided to transmit the operating force introduced into the flexible pulling member 19, thereby directly actuating the locking device 6. The central force direction unit 200 shows another transmission element 11 connected via another coupling unit 206. Similarly, a force direction unit 200 is provided for the third transmission element 11.

[0165] Here, each force direction unit 200 includes a stop 201, which is fixedly connected to the support member 5 of the support arm 3. Near the stop 201, a locking member 203 is disposed on the flexible tension member 19 and connected to it in a force-transmitting manner. When the user pulls the actuating member 12, the locking member moves on the stop 201 of the force direction unit 200, whose radial distance 34a is longer than that of the actuating member 12. Therefore, the force transmission within the transmission element 11 is controlled and transmitted to the locking device 6. During actuation, the flexible tension member 19 cannot pull back the introduced stop 201. This preferably achieves a short and defined actuation stroke 19a.

[0166] The gripping knob of the actuating member 12 is positioned adjacent to the receiving guide rail 23. This allows for comfortable and simple actuation. A stop 201 is positioned radially outward of the fixing device 2 and approximately halfway down the length 34 of the support member 5 of the support arm 3. A second stop 201 is positioned at approximately 75% of the radial distance 34 corresponding to the length 34 of the support arm 3 of the radial gripping device 1. This allows for comfortable actuation by the user near the gripping device 9. Furthermore, the large radial distance 34a from the rotation axis 4a (i.e., including the long lever arm) allows for the transmission of forces for pivoting.

[0167] When the locking device 6 is actuated by the first actuating member 12, which is shown at a shorter radial distance 34a from the axis of rotation 4a, the force direction unit 200, located at a larger radial distance 34a, advantageously ensures that the pulling member will not be pulled out from the guide of the stop member 201. The locking member 203 prevents movement of the flexible pulling member 19. Therefore, the operating force is directly transmitted to the locking device 6 for actuation. The flexible pulling member 19 will not loosen accidentally or uncertainly due to the force direction unit 200. The actuation stroke 19a is determined by the force direction unit 200 and is determinable. Basically, the actuation stroke 19a corresponds to the stroke length required to actuate the fixing member 13, causing it to pull out of the recess 4 of the locking device 6 to transfer the bearing arm 3 to the rotational position.

[0168] Figure 2 A plan view of a radiological system 100 is shown, which includes radiological equipment 50 and a support arm 3. Fixture 2 (see...) Figure 1 (Not shown, thus making the locking device 6 visible in the top view.) The support arm 3 is pivotable about the axis of rotation 4a of the shaft 4 that is configured as a pipe segment.

[0169] The locking device 6 includes a fixing member 13, which is fixed to the bearing arm 3 and biased in the locking position 7 by a biasing device 17. The fixing member 13 is configured as a bolt that engages in a recess 14 of a bore 15 of the locking device 6. The diameters of the plurality of recesses 15 are significantly larger than the diameter of the shaft 16. Therefore, the locking device 6 can be arranged radially outward of the shaft 4 with a simple structure, enabling secure positioning.

[0170] A limiting device 25 for rotation angle is provided. The limiting device 25 for rotation angle is configured as a mechanical stop that limits the rotation angle of the bearing arm 3. The stop is fixed into the recess 14.

[0171] The impact buffer device 28 protects the load-bearing arm 3 from impact and damage. At the same time, the impact buffer device 28 provides effective protection against damage to other objects.

[0172] The patient support unit 31 is secured to the gripping device 9, wherein the motor-driven belt unit 32 can move up and down. In this case, another second gripping device 9 is placed on the carrier 5.

[0173] The housing with unit 32 may be provided with operating button 31a (see Figure 8This is used to actuate, for example, a winding unit driven by a coil spring (which is not visible because it is located internally). When the operating button 31a is operated, the belt can automatically retract and wind up (unloaded) or the belt can be pulled out against the force of the coil spring. Preferably, the belt length is at least 200 or 300 mm. In advantageous configurations, the extendable belt length can be 500 mm or 750 mm or longer. In rooms with high ceilings, this provides the advantage that when not in use, the gripping handle of the gripping device 9 can be raised high enough to not be obstructed and to prevent impact to a person's head. Alternatively, the unused gripping handle can also be suspended in a hook 5a.

[0174] Figure 2 A variation is shown in dashed lines, in which the support arm 3 is placed to or constructed into the radiological device 50. Its advantage is that the fixing device 2 is placed directly into the radiological device 50, allowing for a compact overall structure.

[0175] Figure 1 and Figure 2 The hook 5a shown allows for the hanging of objects. For example, an infusion bag can be attached to it or a patient file can be attached to it. The hook 5a can be attached, for example, welded to the side of the carrier 5. The hook 5a can also be fixedly or repositionably positioned and secured to the carrier by means of tube clamps or a specialized fastening system.

[0176] Three force direction units 200 are arranged laterally along the support member 5 of the support arm 3. The stop member 201 of the force direction unit 200 includes and horizontally guides a flexible tension member 19 along the support member 5. A locking member 203 is fixedly connected to the flexible tension member 19. The actuating member 12 is not visible here. A hook 5a can hold, for example, an infusion bag 30.

[0177] Figure 3 An enlarged sectional view of the shaft 4 and part of the bearing 5 of the radiographic gripping device 1 is shown. Figure 1 Area I. The fixing device 2 is constructed as a fixed support. The fixing device 2 can be fastened to the top plate of the radiation chamber (not shown) by a threaded connection. A pivotable support arm 3 is placed on and supported by the fixing device 2. For this purpose, a pivotable shaft 4 is directly connected to and provided on the fixing device 2. The 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.

[0178] Shaft 4 passes through the intermediate top plate. The intermediate top plate is not fully shown.

[0179] The shielding device 18 is centrally positioned around the shaft 4. Therefore, the opening in the intermediate top plate is closed and covered. Thus, the magnetic shielding located in or on the intermediate top plate can be effectively shielded or closed. The shielding device 18 includes magnetic shielding such that the remaining opening of the magnetic shielding is as small as possible.

[0180] The locking device 6 locks the support arm 3 in the locked position 7 shown by the fixing member 13. Normally, it is biased in the locked position by the biasing device 17, which is currently configured as a coil spring. The support arm 3 is non-rotatably fixed to the locked position 7. Therefore, safety is ensured when using the radiographic gripper 1.

[0181] The actuating 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 tension member 19, or more precisely, a pull rope.

[0182] The transmission element 11 is radially guided to the shaft 4 by a guide roller 21. The transmission element 11 is deflected by the guide roller 21 and guided along the axis of the shaft 4 by a guide unit 20 inside the shaft 4. The guide unit 20 currently includes a tube. The tube is curved to deflect the transmission element 11.

[0183] At the lower end of the shaft 4, the transmission element 11 extends axially through 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 or sleeve. The deflection sleeve 22 is preferably made of plastic with a particularly slippery and smooth surface, thus providing low frictional resistance. This allows the transmission element 11 to deflect with a small radius along the support member 5 of the support arm 3. The support member 5 can be a separate piece, or it can be integrally constructed with the support arm 3.

[0184] The transmission element 11 passes through the intermediate top plate inside the shaft 4. Therefore, it does not require a separate guide on the outside of the shaft 4 that passes through the intermediate top plate. The opening in the intermediate top plate is thus significantly smaller, allowing the pull cord to simply hang straight down parallel to the axis of the shaft 4. The opening required for magnetic shielding in the intermediate top plate is significantly smaller and easier to close than known designs in the prior art.

[0185] At the carrier 5, the transmission element 11 deflects horizontally along the axis of the carrier 5 and is further guided along the axis of the carrier 5. The second transmission element 11 is connected to the first transmission element via the engagement unit 206. The force direction unit 200 ensures optimal transmission of the introduced operating force. This prevents the flexible tension member 19 from becoming ambiguous and, most importantly, from accidentally slackening.

[0186] Figure 4 An enlarged view of the area of ​​the bearing arm 3 with the force direction unit 200 in the actuated state is shown. Figure 1Region II. The stop 201 of the force direction unit 200 is securely connected to the support member 5 of the support arm, for example by threaded connection or welding, and sleeve-shapedly surrounds and guides the flexible tension member 19. Furthermore, the flexible tension member 19 is guided by the stop 201. The locking member 203 is placed on the flexible tension member 19 through a force-transmitting engagement. The position of the locking member 203 on the flexible tension member 19 is adjustable.

[0187] The profile design 202 of the stop 201 expands with an increasing distance 34a from the axis of rotation 4a. This allows the flexible tension member 19 to be advantageously deflected on the stop 201 so as to actuate the locking device 6. The tension member 19 deflects downward, where the actuating member 12 (not shown) is disposed.

[0188] The locking member 203 is spherical and hollow inside. The pulling member 19 passes through the locking member 203. The pulling member 19 has a contact portion 204 that is installed inwardly into the locking member 203. Furthermore, the locking member 203 includes a receiving unit 205 configured as a threaded unit 205, which is configured as a fixing screw. The pulling member 19 passes through the fixing screw. The fixing screw is screwed into the locking member 203. Therefore, the locking member 203 and the pulling member 19 are connected by a force-transmitting engagement.

[0189] A spherical locking member 203 can be placed on the stop member 201 of the force direction unit 200. The locking member 203 can be centered on the rotationally symmetrical sleeve-shaped stop member 201. The tension member 19 shows another tension member 19 connected by a force-transmitting engagement unit 206. This engagement unit is formed by a contact portion 204. The other tension member 19 is disposed on the first tension member 19 through the contact portion 204 in a force-transmitting engagement.

[0190] Figure 5 An embodiment of the engagement unit 206, shown in cross-section, is illustrated. The engagement unit 206 includes a sleeve portion 207. Two transmission elements 11 are disposed inside the sleeve portion. A contact portion 204 is constructed on the transmission element 11, which is currently configured as a flexible tension member 19. The sleeve portion 207 of the engagement unit 206 is closed by a threaded unit 208. The threaded unit 208 is currently configured as a fixing screw, through which one of the tension members 19 passes. In the closed state, the two tension members 19 are connected in a force-transmitting engagement. The illustration of the tension members 19 through dashed lines is intended to illustrate conceivable arrangements of the flexible tension members 19 on the engagement unit 206. Furthermore, other arrangements and connections of the tension members 19 are possible and conceivable. This also applies to the following figures.

[0191] Figure 6A cross-sectional view of the locking member 203 of the force direction unit 200 is shown. The locking member 203 is configured as a spherical gripper. The locking member 203 is configured as a spherical sleeve portion 207. The pulling member 19 is placed on the locking member 203 by means of a contact portion 204 constructed thereon. The locking member is closed by a receiving unit 205, which is currently configured as a threaded unit 205, thereby providing a force-transmitting engagement connection. The locking member 203 can be positioned at virtually any desired location on the flexible pulling member 19.

[0192] Figure 7 A cross-sectional view of the support member 5 of the support arm 3 of the radiographic gripping device 1 is shown. The support arm 3 is transverse to the axis of the support member 5. Figure 1 Region III. A stop 201 is laterally positioned on the support member 5. The stop 201 surrounds and guides the flexible tension member 19. A locking member 203 is not shown. Alternatively, the tension member 19 may pass through the hollow section (see dashed line) of the tube 36 of the support member 5. This advantageously protects the transmission element 11 from contamination. The user will not be entangled by the tension member 19. The risk of injury is minimized.

[0193] Figure 8 A perspective view of a gripping device 9 for a radiological gripping device according to the present invention is shown. The gripping device 9 includes a hook member 29, by which the gripping device can be received in a hooking point 24 of a receiving rail 23. Another support hook 29a is provided on the gripping device 9 for holding additional objects, such as an IV bag 30. The gripping handle 31 can advantageously be flipped upwards and hooked into the support hook 29a. This minimizes the risk of injury and impact. The long legs of the hook allow for a large holding angle 35 up to 60° or higher without the risk of the hook legs slipping off the receiving rail 23.

[0194] exist Figure 8 In the image, one can recognize the operating button 31a, constructed on the belt unit 32 and currently on the gripper of the gripping device 9, to pull out the belt 32e via a coil spring (not shown and disposed internally) or to pull out the belt 32e against the tension of the coil spring. The gripper is positioned to a rod 32b that rotates together with the belt unit 32. The belt unit 32 is positioned to pivot via a sliding member 32c. The sliding member 32c acts as a support unit and is positioned between the upper support of the retainer 32a and the enlarged head 32d of the rod 32b, so as to enable easy pivoting of the belt unit in the direction toward the patient. Although the belt 32e can essentially twist around itself, it can cause problems in operation if the belt is wound crookedly and incorrectly.
