X-ray apparatus relates to medical instrumentation and has a predominantly medical use.

There are many equivalents to various foreign firms Siemens (largest to thunovska devices are composed of a digital control system and registration of x-ray image Overview avenues listed firms).

Models of these companies are similar in layout design solutions, the main common feature of which is that they are specialized for certain medical actions diagnostic or surgical. At a more General approach all existing x-ray units can be characterized so that diagnostic devices allow you to Orient the patient in a wide range of angles, but do not provide a comprehensive close access of the doctor to the patient when performing studies and, therefore, not suitable for surgical intervention. On the contrary, surgical apparatus cannot perform the orientation of the patient in a wide range of angles that is required for a diagnostic action. In a more detailed approach to the analysis of various characteristic types of x-ray units are presented in the attached table.

Known (Review prospect Siemens) x-ray apparatus Angioscopy D 40 (ANGIOSCOP D40) Siemens, selected as a prototype. It consists of a lifting body, C-shaped tripod with multiple degrees of freedom on which you have installed x-ray equipment, a table for a patient with multiple degrees of freedom, control and the region is on a tripod with the x-ray apparatus and for patient table and closing link, which used the space for installation of the apparatus. Bearing element is C-shaped tripod is installed on a floor of a room, and the element table for the patient is installed on the ceiling of the room. One of the degrees of freedom of a C-shaped tripod made in the form of two C-shaped rails, and the other in the form of two C-shaped sectors, nested one within the other and one of which can rotate in the other. The x-ray emitter and the receiver amplifier x-ray image installed on opposite ends of the rolling stock sector C-shaped tripod by means of brackets.

A disadvantage of the known construction is that it requires the premises for installation of the apparatus of the increased requirements, as carrying case is designed as a set of bearing elements with closing link in the form of the space, and the bearing element is C-shaped tripod is attached to the floor of the premises, the element of the table is attached to the ceiling of the room in which you installed the device. In fact, the room should be equipped as part of the design of the device, guides the bearing member C-shaped tripod should be placed directly in the floor of the room. Such a device cannot be run in mobilemoney side due to the large size of the bearing member C-shaped tripod. In addition, the described apparatus is specialized, because of their layout design features does not provide the rotation of the table at large angles (up to 90o), as required in the diagnosis of many diseases, and is not, therefore, universal.

The objective of the invention is providing an apparatus of the properties of universality (i.e. suitability for surgical and diagnostic actions) and improving access of the doctor to the patient when medical services (surgical and diagnostic).

This task is solved in that in the known construction the bearing body is made flat in the form of a plate, is further provided with a drive rotation established on the basis of turning in a vertical plane relative to the short side of the table, guides for C-shaped tripod made in the form of consoles, attached perpendicularly to a higher plane specified housing with movement of the C-shaped tripod on these guides, the x-ray emitter and the receiver amplifier x-ray image installed on opposite ends of the rolling stock sector C-shaped tripod by Singh the amplifier x-ray image at a certain angle from the plane of the sector-shaped tripod. Each of the synchronized movements are made in the form of synchronized drive (e.g., Electromechanical), installed at one end of the rolling sector C-shaped tripod arm attached at one end to the output shaft of the specified drive, and the x-ray emitter or receiver amplifier x-ray image is installed on the opposite end of the lever. In the plate carrier body has a hole for passage of a table, which allows to reduce the length of the guide. Each synchronized mechanism can be performed in various ways, for example, similar to the C-shaped tripod, i.e. in the form of two sectors, nested one within the other, one of which can rotate in the other. Described above is the simplest form of this mechanism. The minimum number of guides for practically important case is two, one above and one below the carrier body.

The invention is illustrated by drawings Fig.1 and Fig.2, which presents a General view of the x-ray machine.

X-ray apparatus includes a bearing housing 1, made in the form of plates, a table for patient 2, secured to the support housing 1 with a linear movement in three mutually perpendicular external housing-sector 4, installed on the guides 3 can move along them, and the inner case sector 5, attached to the external housing-sector 4 for rotation about the axis of sectors, two synchronized drive 6 and 7, mounted on the opposite ends of the inner movable housing-sector 5, two levers 8 and 9, each of which one end is mounted on the output shaft of the synchronized drive 6 or 7, respectively, the x-ray emitter 10 and receiver-amplifier x-ray image 11 installed on the ends of the levers 8 and 9, respectively, the base 12 with a drive of rotation 13, where the hinge is installed bearing body 1. Bearing housing 1 provided with a hole for the passage of table 2. Directions of possible movement of the components of the x-ray apparatus is indicated by arrows.

When performing surgical and part of the diagnostic action doctor, manually moving the table 2 with the patient in three mutually perpendicular directions and using the built-in actuator housing-sector 4 along the guide rails 3, by rotating the housing sector 5 relative to the housing sector 4 and turning the levers 8 and 9 with respect to the axes of synchronized actuators 6 and 7, respectively, can provide the turn in any direction inside a circular layer with diameter determined by the diameter of a C-shaped tripod, and a thickness defined by the lengths of the levers 8 and 9. For all practical purposes it is sufficient to choose the length of the levers 8 and 9 such that they provide the deflection angle of the optical axis of the x-ray radiation from a plane-shaped tripod on the 30o. Thus, the inner radius of the C-shaped tripod and the length of the lever 8 or 9 are on the one hand from the relation 1=R, where R is the inner radius of the C-shaped tripod- the specified angle,=/6 (i.e.=30o), 1 is the length of the lever 8 or 9 in an arc, on the other hand the inner radius of the C-shaped tripod must ensure that the placement of the table with the patient, focusing image and the vertical movement of the table with the patient in the practical range of up to 400 millimeters. At the same time, turning the bearing housing 1 relative to the hinge base 12 with a drive of rotation 13, the physician when performing other diagnostic action may give the patient a tilt angle in the vertical plane 90owhat is required for the efficient movement of contrasting solutions in internal cavities of the patient during atheistic doctor explained Fig.3, 4, 5, 6. In the treatment/diagnosis of injuries of the lower extremities of the patient they should be off the table for special overhead brackets. In this case, the patient is placed, as shown in Fig.5 and table 2 half vidvigayt into the hole And lifting body 1. The presence of holes And, thus, reduces the length of the guide 3 and, hence, to make the design of the apparatus is more compact as a whole. When all positions of the elements x-ray apparatus and, hence, for all medical activities shall have access to the doctor to the patient from all sides, narrow C-shaped tripod is not for this big obstacles. In fact, the table can accommodate up to 4 people, medical staff, and each will have access to the patient, which is very important in the surgical action. This circumstance allows the physician with the convenience to perform surgery.

The property of universality is achieved by the fact that the entire apparatus, including a C-shaped tripod x-ray equipment and the patient table, mounted on a common bearing housing, which is provided with a drive rotation relative to the short side of the table. Thus, while maintaining all traditionrich action it also provides vertical orientation of the patient in a large range of angles required for diagnostic actions. This carrying case is made flat, and guides a C-shaped tripod x-ray equipment are perpendicular to the plane of the lifting body and spaced up and down. Actuator-shaped tripod is located in the vicinity of the guides at the top and bottom. Closing element is a narrow beam external sector-shaped tripod. All together does not interfere with the access of the doctor to the patient at all angles of the lifting body (and therefore the patient). That is, the device can be used as surgical with better than that of the prototype access physician to the patient. At all angles of the lifting body effect kinematic closure design also preserves the orientation of the optical axis of the x-ray apparatus relative to the patient specified by the physician with the remote control, the physician has the opportunity manageable to change the specified orientation in the process of tilting the patient. That is, the device is fully preserves the quality of specialized diagnostic analogues.

The property of universality in this case, similarly to the property Rasch on patient behaviors using only one device. Ensuring full access of the doctor to the patient when performing diagnostic and operative actions (i.e. usability) can also be attributed to the expansion of functionality, since this property is one of the most important performance properties of the considered devices. As a consequence of the properties of universality property should reduce the cost of medical services, since it provides one of the medical action of the known list, and thus replaces the 2. ..3 specialized, that is not universal analogue having different functionality, but if taken together have the same capabilities. The list of official names of medical actions proposed x-ray unit attached.
