Description

The present invention relates to a table motorized operation of the type comprising a tray horizontal support for a patient, provided at least with part of a side rail for accessories, said plate being fixed on a chassis mounted on wheels.

The operating table of the present invention is intended in particular, but not exclusively, for surgical procedures.

During surgical operations, patients are transferred from one place to another, and more especially from their room to the operating room where they must undergo the surgery. The transfer patients are conventionally performed by means of transport trolleys which are moved manually by the medical staff. Patients are transferred from their bed to the transport cart to be driven to the operating room, where they are then transferred from the cart transport to the operating table. Such transfers of the patient remain relatively unaffected and present for medical personnel risk of injury. Similarly, depending on the condition of the patient, such a transfer may also cause or aggravate patient injury.

It is described in the European patent application EP0917868, an operation table top connected in such a way removable to a frame on wheel. Advantageously, the plateau can be transferred successively from the mobile chassis to a fixed support column, and vice versa. Although the transferring the patient to the operating table is no longer performed by direct manipulation on the patient, the described system however requires several people to ability to move the tray from one bracket to another. Such present system further the disadvantage of being relatively unwieldy.

It is also known in the prior art of trolleys including a motorized base. However, systems for controlling the engine are systems manual control. The handling of such trolleys remains then relatively laborious for the medical staff of the even having to guide the cart with one hand, the other hand now the control system.

From the international patent application WO0151910 we know a configured radiotherapy treatment table to support and position a patient during the treatment and mounted on a chassis comprising means forming columns which are mounted on a wheeled chassis mobile. The table includes a positioning device and direction for detecting the position of said table compared to a radiotherapy station and to drive and direct said table to come in one desired position at said station, in response to measuring his current position. Such a table presents however limits in that its displacement is conditioned directly by the treatment equipment. For can be moved, the treatment table will have to necessarily be located near the station of radiotherapy.

The present invention intends to remedy disadvantages of the prior art.

To do this, the present invention is of the type described above and is remarkable in its widest, in that said table comprises a block of control of the displacement of the operating table fixed on the side rail and coupled to a base comprising an engine block attached to said operating table, said control block comprising control means for actuating the operating or stopping said engine block.

Preferably, the control block is fixed on the side rail removably.

Advantageously, said control block constitutes guide arm of said operating table.

Advantageously, the coupling of the control block and the motor unit is made electrically or optically.

In a preferred embodiment of the invention, the coupling of the control block and the engine block is realized by means of infrared, said motor unit comprising a infrared sensor. In such a configuration, the infrared emitted by said control block are advantageously directive, so as to present a zone emission limited to a surface surrounding the sensor infrared engine block, said surface being inscribed in the upper surface of said base.

Advantageously, the control means transmit to the motor block of the non coded motion commands specific to said operating table. So when the control block is configured to be set so removable on the side rail formed around the plateau of the operating table, said control block will be able to adapt and operate with any operating table equipped a base comprising an engine block with which said block control may be coupled.

According to an advantageous embodiment of the invention, said table further comprises a detector of fixing said control block on said operating table. The purpose of said fixation detector is to deactivate the engine block in the absence of attachment of said control block on said operating table.

Advantageously, said engine block is fixed under the support of said operating table, preferably centrally in relation to said support.

Advantageously, said engine block controls at least one of the wheels of said operating table, and preferably a wheel disposed centrally with respect to said support.

The present invention also relates to a accessory for motorized operating table of the type including a horizontal tray to support a patient at least partly provided with a side rail for accessories, said plate being fixed on a frame mounted on wheels, said accessory consisting of guide arms of said operating table removably attached to the rail lateral of said support. Said guide arms comprise a control block for moving said table operating device coupled to a base comprising an engine block, as well as control means for actuating the operating or stopping said engine block.

The coupling of the control block and the engine block is performed optically, and preferably by infrared. The infrared signals emitted by said control block and received by a infrared sensor of said engine block are directional and advantageously have a conical emission zone of which the intersection with the upper surface of the base forms a detection surface including the infrared sensor of the engine block.

Advantageously, the control means transmit to the motor block of the non coded motion commands specific to said operating table. So, as indicated previously, it is then possible to use the block of control on any operating table from then on that it is equipped with the necessary equipment, namely a motor block allowing coupling with the control block, the coupling can be realized electrically or optically. Optical coupling will however be preferred to facilitate the manipulation of said control block.

The present invention also relates to a operating system comprising a plurality of tables as previously described, at least one operating tables being equipped with an accessory such as described above. The system is configured so that it advantageously comprises a number of guide arms less than or equal to the number of operating tables.

• la figure 1 illustre une vue en perspective d'une table opératoire selon l'invention ; et
• la figure 2 illustre une vue agrandie en perspective des bras de guidage selon l'invention.

The invention will be better understood from the following description, given purely for explanatory purposes, of one embodiment of the invention, with reference to the appended figures:

• FIG. 1 illustrates a perspective view of an operating table according to the invention; and
• FIG. 2 illustrates an enlarged perspective view of the guide arms according to the invention.

FIG. 1 illustrates an operating table (1) according to the invention, intended in particular for interventions Surgical.

Said operating table (1) is of the type comprising a horizontal tray (2) for supporting a patient, which is fixed on a chassis (9) mounted on wheels.

Said plate (2) is advantageously formed of four parts (2a to 2d) intended to receive respectively the patient's head, back, pelvis and legs. In addition, said parts (2a to 2d) are connected to each other others so as to allow a respective adjustment of the inclination of each of said parts (2a to 2d).

Each part (2a to 2d) of said plate (2) is provided with side rails (3). Advantageously, the parts (2a and 2d) respectively constituting the front and the rear of the said tray (2) are also provided, respectively on their front and rear faces of a side rail. Said rails thus arranged around said plate (2) allow to attach the necessary accessories to the surgeon during surgery. Said rails are in particular for the hanging of the tools of the surgeon.

Said operating table (1) further comprises arms (6) which are respectively fixed on the side rails of the part (2b) of said plate (2).

Said guide arms (6) constitute a block of control (7) to control the movement of the operating table (1). To do this, said control block (7) is coupled to a base comprising an engine block (8), said base forming part of said table operative (1). More particularly, said base, disposed under the plate (2), constitutes a part of the chassis supporting said plate (2).

It should be noted that, by the use of the term control of the moving means starting the engine, stopping of the engine and control of the speed of movement of said operating table (1).

Similarly, we mean by moving the table procedure (1), the advancement or retreat of the latter for move from one location to another. So when the block motor (8) is activated by means of the control block (7), the operating table (1), according to the order operated via said control block (7), will move forward or backward automatically. The shutdown of the engine block will lead to the shutdown of the automatic movement of said operating table (1). he it is obvious that stopping said engine block (8) will not prevent a voluntary manual displacement of the said operating table (1).

Coupling said control block (7) with said block motor (8) is performed electrically or optically.

More specifically, the control block (7) is coupled with a receiver for receiving the electrical signals or optical transmitted by said control block (7), said receiver being itself connected to an embedded computer controlling said engine block (8).

In a preferred embodiment of the invention, the coupling is performed optically, and advantageously by infrared. For this purpose, the engine block (8) comprises a infrared sensor (not shown).

To avoid any interaction with tables also equipped with an engine block equipped with a infrared sensor, said tables being arranged in the infrared reception field emitted by said block of control (7), the emission of infrared is directive. More specifically, the emission zone is limited to a surface surrounding the infrared sensor of the engine block (8), said surface being inscribed in the upper surface of the basement. More precisely, the emission zone is a conical zone whose intersection with the upper surface the base forms the detection surface containing the sensor infrared.

Figure 2 shows an enlarged view of the block of control of the guide arms (6) fixed on the table operative (1) of Figure 1.

The guide arms (6) are respectively provided with one of their ends of a fastener (10) intended to be fixed on the rails for accessory surrounding said tray (2). Advantageously, the elements fastening means (10) are attached to the lateral rails (3) of the part (2b) of said plate (2).

In this embodiment, said element of fastener (10) has a cavity configured to allow clipping said fastener element to said side rail (3).

Said guide arms (6) present at their free ends a zone forming a handle. One of the handles is advantageously provided at its end with a button of security that can rotate along an axis identical to the axis longitudinal axis of the handle area. The said button security allows to activate the moving of the table (1) (forward or reverse), and control his speed. In order to facilitate its manipulation, said security button has a fingerprint corresponding substantially to the shape of the thumb of a hand.

Said guide arms are connected to each other by a transverse bar (11) which supports the block of control (7) for controlling the movement of said operating table (1).

Advantageously, said procedure comprises a fixing sensor (not shown) of said block of control (7). Thus, in the absence of fixation of said block of control (7) on the lateral rails (3) of said plate (2), said fixing detector will deactivate the motor unit (9).

One of the main advantages of the present invention is to provide guide arms (6) that can be adapted to any operating table (1) equipped with an engine that can be electrically or optically coupled with said arms of guiding (6). As a result, it will be advantageous for orders emitted by the control block (7) to said engine block (8) consist of coded displacement commands whose coding will not be specific to an operating table (1). So, in the case of a system with multiple tables operating procedures (1), it will not be necessary to necessarily as many guide arms (6) as tables operative (1).

The invention is described in the foregoing as example. It is understood that the skilled person is able to to realize different variants of the invention without as far out of the scope of the patent.
