Description

[0001] The invention relates to a patient positioning table for positioning a patient.

[0002] Patient tables, also called patient tables, are used in the medical field, particularly for medical imaging and / or for examination and / or treatment procedures, such as surgical interventions or radiation therapy. For example, a patient table may be associated with an imaging device or other medical equipment, such as a computed tomography (CT) scanner.

[0003] Patient tables can have several, in particular three, axes of movement or degrees of freedom. For example, patient tables can be adjusted in height (1st degree of freedom). A table superstructure, which serves to support a patient bed for positioning a patient, can be adjustable at least along its longitudinal axis (2nd degree of freedom). The patient bed itself can be adjusted along its longitudinal axis relative to the table superstructure (3rd degree of freedom). At least one motor can be provided for each axis of movement for automatic adjustment along that axis. Furthermore, three additional degrees of freedom can be provided, in particular three rotational degrees of freedom, e.g., for tilting or swiveling.

[0004] To move such treatment tables, multiple axes, e.g., six axes, are required, each equipped with a motor. For precise movement, a position sensor is necessary for each motorized axis. Additionally, a redundant, identical sensor is used to eliminate the risk of table failure and ensure safe radiation or treatment of the patient.

[0005] Due to these high specific requirements in the medical field, it must be ensured that manual operation or a manual return is also possible in the event of a failure of the electrical control system and / or electrical operation. Rotary levers or cranks can be provided for this purpose, which can be coupled at an externally accessible point. The rotation or torque applied there is redirected via gears, which is complex and elaborate given the limited installation space and the necessary safety requirements. The 90° redirection of the rotary motion has previously been achieved with a complicated and expensive mechanism within the gearbox or by a gear assembly at the gearbox output.

[0006] The invention is therefore based on the objective of providing a patient positioning table with a vertical adjustment device that allows safe manual vertical adjustment and / or return. The invention particularly solves the problem that the manual operation is suitable for medical applications and medical devices and, in particular, meets hygienic requirements (protection against liquid media and corrosion, washability). Furthermore, it is an objective that the means used for this purpose remain usable even after prolonged periods of non-use.

[0007] To solve this problem, the invention provides a patient positioning table for positioning a patient according to claim 1. Advantageous embodiments are described in the dependent claims, the description, and the accompanying figures.

[0008] Regardless of the grammatical gender of a particular term, persons with male, female or other gender identities are included.

[0009] The patient positioning table according to the invention is designed for positioning a patient. Patient positioning table () comprising - a lying board on which a patient can be positioned, - a vertical adjustment device () for adjusting the height of the lying board, comprising an electrically and manually operable and / or operable drive device, wherein the drive device includes an electric drive means for electric height adjustment, - a coupling interface for coupling with a crank, wherein the coupling interface is configured to receive and / or transmit a torque provided by means of the crank, - wherein the drive device includes a feedback interface, - wherein the coupling interface is connected to the feedback interface by means of a flexible shaft, wherein the flexible shaft is configured to transmit and / or guide the received and / or transmitted torque of the coupling interface to the feedback interface, wherein the drive device is configured to use and / or convert the transmitted and / or guided torque of the feedback interface for manual height adjustment.

[0010] The patient positioning table can be designed for positioning a patient during radiation therapy. The patient positioning table is specifically designed for positioning a patient during a surgical procedure. In particular, the patient positioning table is designed for positioning a patient during medical imaging in an MRI, CT, or other imaging device.

[0011] The examination table is technically designed for medical imaging and / or radiation therapy. It is made of a robust material that offers both high stability and good radiolucency. The table allows for safe and comfortable patient positioning to achieve optimal imaging results or precise radiation delivery. It preferably features a smooth surface for easy cleaning and disinfection. Furthermore, the table can be equipped with special attachment points to securely fix the patient during imaging or radiation therapy and minimize movement.

[0012] The patient positioning table, in particular the lying surface, can assume two states: an access position and an operating position. In the access position, the lying surface is at a first height. This first height can be a minimum height and / or the lowest position of the lying surface. In the operating position, the lying surface is at a height greater than the first height; specifically, the lying surface is at a height of at least 50 cm, preferably at least 100 cm, above the floor. The first height is specifically an access height, allowing a patient to climb onto the lying surface, sit down, and / or lie down.

[0013] A vertical adjustment mechanism is used to adjust the height of the treatment table. This allows the table to be set to an ergonomic working height and the patient to be positioned comfortably. Additionally, the vertical adjustment mechanism can be used to switch between the access and operating positions.

[0014] The vertical adjustment device is designed and / or configured for adjusting the height of the lying board. In particular, the vertical adjustment device is designed for manual and automatic, especially electric, height adjustment of the lying board. Specifically, the terms manual / electric operation and / or manual / electric operation refer to manual / electric height adjustment of the lying board.

[0015] The vertical adjustment device comprises a drive unit, the drive unit being designed and / or configured to effect, control, and / or execute the manual and electric height adjustment of the lying board. In other words, the drive unit is designed to adjust the height of the lying board both solely based on human assistance (e.g., power, energy, force, and / or torque) and based on electrical assistance (e.g., an electric motor). Preferably, a mixed operation of manual and electric height adjustment is excluded and / or deactivated.

[0016] The drive device comprises an electric drive element. The electric drive element is, for example, an electric motor and / or stepper motor. The electric drive element is specifically designed to output torque and / or rotary motion. The drive device is preferably configured to convert the output torque and / or rotary motion and / or to adjust the height of the reclining board.

[0017] Alternatively and / or additionally, the electric drive can be designed as an electric linear actuator. Electric linear actuators can use an electric motor and a threaded spindle to control the vertical movement of the bed. They offer precise and smooth height adjustments that can be easily controlled via operating elements.

[0018] Particularly preferably, the drive device comprises a scissor foot, wherein the electrical drive means is formed, two crossed struts of the scissor foot which are connected at a common point or axis in order to pivot it or these.

[0019] These drive mechanisms enable flexible and precise height adjustment of the treatment bed to meet the requirements of medical care. They offer comfort for the patient and facilitate the work of medical staff.

[0020] The electric drive system is preferably controllable via control elements that allow medical personnel to position the patient precisely and easily.

[0021] The coupling interface is designed for coupling with a crank. A crank is generally understood to be a mechanical operating element, wherein the operating element is designed to enable mechanical movements or actions by manual turning, lifting, or pushing. Furthermore, the term crank can also refer to a rotary handle, a toggle lever, a turntable, a handgrip, a wheel, a crankshaft, a winch, a spindle, or a knob. The crank may be enclosed by the patient positioning table, for example, arranged in or on a housing.

[0022] The coupling interface is designed to receive and / or transmit torque and / or rotary motion supplied by the crank. For example, the crank is coupled to the coupling interface, e.g., by insertion and / or locking, whereby the crank is then manually rotated, and the torque and / or rotary motion introduced by the rotation is received, transmitted, and / or transferred by the coupling interface. The coupling interface is preferably designed for reversible coupling with the crank, for example, by means of a plug connection, clamp connection, and / or locking mechanism.

[0023] The drive device has a feedback interface and / or the feedback interface is associated with the drive device. The feedback interface can be a concealed interface and / or an interface that is coupled or already connected during operation or normal use. The feedback interface is designed for connection and / or coupling with the coupling interface. In particular, the feedback interface is designed to receive and / or transmit a rotary motion and / or torque. The feedback interface is specifically designed to transmit and / or provide a received and / or transmitted torque and / or rotary motion. Preferably, the feedback interface and the coupling interface are permanently and / or irreversibly coupled and / or connected, with the coupling and / or connection being designed to transmit a torque and / or rotary motion.

[0024] The coupling interface is connected to the feedback interface by means of a flexible shaft, the connection being reversible, preferably permanent. The flexible shaft is designed to transmit and / or guide a torque and / or rotational movement from the coupling interface to the feedback interface. The flexible shaft is, in particular, flexible. Specifically, the flexible shaft is torsionally stiff and / or resistant to twisting. In other words, the flexible shaft is resistant to torsion or twisting. In technical or physical contexts, this means, in particular, that the flexible shaft is designed such that it experiences only minimal or no twisting under the influence of a torque. In the context of the flexible shaft, "flexible" is understood to mean, in particular, that the shaft is bendable, compressible, axially extensible, shearable, and / or kinkable.Bending is a deformation in which a shaft curves around a transverse axis. This can preferably occur along the longitudinal axis. Axial elongation and compression refer to the change in length of the shaft due to axial forces (in the direction of the longitudinal axis). Elongation occurs when the shaft is stretched, while compression occurs when it is compressed. Shear refers to the displacement of adjacent layers within a material or structure. This can cause the shaft to change shape without twisting or bending. Buckling is an instability in which the shaft deviates laterally or deforms laterally under a load.

[0025] The torque and / or rotary motion transmitted by the flexible shaft from the coupling interface to the feedback interface is used, converted, and / or transformed by the drive device for manual height adjustment. In other words, the drive device is preferably designed to effect the height adjustment by means of a torque and / or rotary motion output by the drive element as well as by means of a torque and / or rotary motion transmitted by the flexible shaft. For example, the drive device converts the torque transmitted by the flexible shaft to the feedback interface into a height adjustment and / or uses it to operate, for example, the scissor foot.

[0026] The present invention relates to an innovative solution for utilizing the limited installation space in a patient bed to effectively employ manually applied torque for precise height adjustment. This innovative technology makes it possible to efficiently utilize manually applied torque to generate a precise rotary movement for height adjustment and to direct it precisely to the required points.

[0027] The invention ensures cost-effective implementation. Implementation is carried out in a way that optimizes resource utilization and is therefore highly economically attractive. One advantage of this invention is its reliability, even after extended periods of non-use. This guarantees continuous and dependable functionality whenever required. The innovative design and construction, and in particular the materials used, contribute to the invention remaining operational even under demanding conditions. Furthermore, the invention meets the stringent hygiene requirements of the medical field. The materials used and the design are geared towards facilitating easy cleaning and disinfection. This is crucial for meeting the high standards in the medical field and ensuring patient safety.

This innovative feature allows the enclosure to be adjusted, extended, or reduced in size when changing its height. With a folding principle, the enclosure is divided into several interconnected sections. These can be folded either horizontally or vertically to open or close the enclosure. This design offers flexibility and ease of use. If required, the enclosure can be fully extended to provide complete access to the underlying mechanisms. With the telescopic mechanism, the enclosure slides on rails or guide elements, allowing it to be moved vertically. An enclosure system based on the telescopic mechanism specifically comprises multiple enclosure elements.When the lying board is raised, the cover panels are released in a box-like fashion to conceal the vertical adjustment mechanism and / or the scissor mechanism. When the lying board is lowered, the cover panels are again retracted into each other in a box-like fashion.
