ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a support system for an examination subject of the type having a mechanism base onto which a support plate for accepting a treatment and/or examination subject can be detachably attached.
2. Description of the Prior Art
Support mechanism systems of this type are normally utilized in the medical field. The patient to be treated or examined is situated on the support plate in a treatment or examination room. Support plates are known in the form of operation plates. An operation plate is fashioned for carrying out a particular operative intervention at the subject. The operation plate can be fastened via specific fastening elements at the mechanism base that is firmly arranged in the operating room. Normally, the already anaesthetized patient, already lying on the operation plate, is brought from another room by means of a transport gurney into the operating room, where the operation plate is taken from the transport gurney and is fastened at the mechanism base, the operation plate being detachably fastened at said transport gurney for this purpose. However, only operation plates which have appropriate fastening capabilities or which have fastening elements compatible with the fastening elements provided at the mechanism base, can be attached to the mechanism base.
Another known support mechanism system has a support plate that is fashioned as a radiological support plate and that has a more or less large radiation-transparent region making it possible to undertake transillumination exposures of a patient lying on the radiological support plate, using a fluoroscopy device such as an X-ray device. For example, the radiological support plate can be fashioned as an angiography table for that specific application. A radiological support plate is often firmly and detachably connected to the mechanism base; however, when the support plate is detachable, specific fastening means are utilized, which exclusively enable the fastening of such radiological support plates. The mechanism base is also situated in a specifically provided examination room.
The known support mechanism systems have the disadvantage that each system is limited to allowing only certain support plate to be attached to the mechanism base, due to the configuration of the fastening means. For example, when three operation rooms and, for example, two rooms for carrying out radiological examinations are provided in a hospital, considerable difficulties occur when all three operation rooms are occupied simultaneously and an emergency operation must be promptly undertaken. This is not possible in the radiological examination rooms, since the support plates provided there, allow X-ray-diagnostic examinations and also minimally invasive treatments, for example by means of a catheter, but they are not suitable for carrying out operations at an open vessel or cavity, since the hygienic requirements and the device equipment are not sufficient.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a support mechanism system, which is highly flexible, so that aforementioned bottlenecks can be prevented.
For solving this problem with respect to a support mechanism system of the type described above, the inventive support mechanism system includes a transport gurney or cart and at least two support plates that can be fixed at the transport gurney, with one support plate being utilized for carrying out an operative intervention at the subject and the other one being fashioned as a radiological support plate having at least one radiation-transparent area. The plates are optionally attachable by the same fastening arrangement, at the mechanism base, and the base has at least one connector for an implement or component of a medical operating system for examination, treatment or surgery.
The system includes support plates of various types, namely at least one operation plate and at least one radiological support plate. A number of each type can be provided. Each plate type is specifically fashioned with regard to the hygienical and technical requirements associated with the procedure or procedures for which the plate is intended. As a result of the utilization of homogenous, identically fashioned fastening arrangements at each of the procedure-specific plates, as well as at the mechanism base (or at respective mechanism bases arranged in different rooms), it is possible to optionally arrange any of the support plates at any mechanism base in the inventive system. One or more connectors at the mechanism base itself supply required operational support such as current, gases etc. for implements or components, so that the devices necessary for the required treatment or examination can be connected. The inventive optional exchangeability of the respective support plates has the considerable advantage that the room containing the mechanism base can be used as an operation room, for example for emergencies, and can be used for radiological examinations as well. Apart from this significant advantage, another advantage is that only the homogenous type of fastening arrangement is needed, i.e., it is no longer necessary to provide different fastening arrangement for different plate-base-systems, as has been hitherto necessary in the prior art.
Inventively, each support plate situated at the mechanism base can be adjusted in height and is tiltable around at least one axis extending in the longitudinal direction and at least one axis extending in the transverse direction of the support plate. The inventive system provides this tilting possibility for each support plate type, i.e., the operation plate (which has conventionally mounted to tilt around its longitudinal axis and around one or more transverse axes) and the radiological support plate (which has not been conventionally mounted to as to be tillable) can now be more or less fully adjusted as needed. Apart from adjustment in height, rotation around the vertical base axis is also possible.
The radiological support plate can be inventively movable along an axis extending in the longitudinal direction relative to the support plate and along an axis extending in the transverse direction relative to the support plate. This floating mounting has the advantage that the patient can be moved relative to a radiological examination system, an X-ray device for example, in order to position the “region of interest” with respect to the image pickup system. It is expedient for the radiological support plate to be variable in length.
In another inventive embodiment, at least one electromechanical or hydraulic adjustment device is provided for the support plate situated at the mechanism base, and at least one electromechanical or hydraulic adjustment device for effecting tilting of the support device can be operated via a power supply and via a power supply independent thereof. The integration of the adjustment device in the mechanism base makes it possible to make the adjustment device accessible only at the side of the base, and each support plate can be moved by means of this adjustment device. Moreover, the operability of the adjustment device via an independent power supply has the advantage that a support plate that has been adjusted to a certain position can be brought again into an initial position, in which it can be removed from the mechanism base by means of the transport gurney, if the main power supply fails.
Furthermore, it is expedient for each support plate and base mechanism to have any crevices or recesses sealed, or for the plate to be sealingly encased, so that fluids cannot penetrate into the area of possible joint or motion mechanics or connections or into the area of the fastening arrangements. Such sealing or casing offers a secure protection against penetration by fluids such as blood or other body secretions and against fluids required in an interventional procedure, this being important for hygienical reasons. An encasing such as a lamella encasing can be provided at the mechanis
