Description

[0001] FLOOR LOCK SYSTEM FOR AN OPERATING TABLE

[0002] TECHNICAL.. FIELD

[0003] The present invention relates to a floor lock system for an operating table, which comprises a plurality of lock mechanisms located on the operating table for locking the table.

[0004] BACKGROUND OF THE INVENTION

[0005] In the literature, operating tables are generally designed as mobile and have lock mechanisms during the operation. While the operating table controlled by the microprocessor unit completes its movements, the microprocessor unit first checks the lock status of the table to ensure the safety of the operating table, patient, and surgical team, and enables the positioning of the operating table when it is in a locked state. Therefore, in order to prevent situations that may directly affect the use and safety of the table, such as electronic card failure during the operation, emergency controls designed to be used in case of an emergency are provided on the bodies of the operating tables. These controls act directly on the pistons, valves, and motors, which move the parts of the operating table, thereby carrying out the movements; and they must be used under control. Operating tables which move without being controlled by a microcontroller, sensor, or electronic circuit have the risk of tipping, moving unintentionally, and collision if the wheels are not locked. This may cause operating table failure and threaten the safety of the patient, the surgical team, and the technical team servicing the table. Due to their design, operating tables have the best static state for cases where their wheels are locked, and they have also balanced centers. Thus, in every' positioning of its parts, the operating table provides a safe setting for the patient thereon, the surgical team, and the technical sendee. In cases where the operating table remains unlocked, it can move and tip over due to the force that may occur, considering the load of the patient on the operating table and / or the positions that the operating table can take. This means that the safe setting created for the surgical team and the patient is eliminated.

[0006] A system for locking the operating table is known in the state of the art. Accordingly, the invention numbered EP3856114 relates to a mobile operating table column having an integrated stability system. In the said invention, there is a switching unit, which is connected to a controller for controlling the actuated adjustment elements. However, in the said invention, the buttons are not energized by means of the switching units. In addition, in case of an emergency corresponding to a technical problem that may occur on the operating table, there is no locking structure for an emergency to enable unlocking or locking.

[0007] In conclusion, all the above-mentioned problems have made it necessary to make a novelty in the state of the art.

[0008] OBJECTIVE OF THE INVENTION

[0009] In order to eliminate the above-mentioned disadvantages and introduce new advantages to the technical field, the present invention relates to a floor lock system for an operating table.

[0010] An objective of the present invention relates to a floor lock system for an operating table, which prevents the posi tioning of the table completely electro-mechanically by means of switching units without microprocessor monitoring, when the operating table is not locked to the floor in an emergency with security vulnerability of the operating table.

[0011] Another objective of the invention is to provide a floor lock system for an operating table, having buttons for locking and unlocking of the operating table, which are energized in both conditions, i.e. when the lock mechanisms are locked and not locked, and control buttons which are energized only when the lock mechanism is locked.

[0012] SUMMARY OF THE INVENTION

[0013] In order to realize all the above-mentioned objectives which will be clear from the following detailed description, the present invention is a floor lock system for an operating table, which comprises a plurality of lock mechanisms located on the operating table for locking the table. Accordingly, the novelty of the present invention is that it comprises a first switching unit which is pressure-sensitive and closes when the control element emerging from at least three different free points on the lower part of the table forms a plane by means of a plurality of pistons during the locking of the operating table, and a second switching unit which is pressuresensitive and closes when the operating table is balanced on the floor plane by a piston emerging from at least one free point of the operating table where no other piston emerges; the said switching units are set to inform the microprocessor table control system about the open or closed positions of the lock mechanisms when the microprocessor table control system is activated, and the closed positions of the lock mechanisms are set to be detected and controlled by the table control system; the said switching units are set to be controlled by an electro-mechanical emergency control system when the electro-mechanical emergency control system is activated upon an emergency switch is manually switched to the closed position, and when the switching units are in closed position, one or more control button(s) electrically connected to the said switching units by means of a plurality of control valves corresponding to the actuator control elements are set to energized through the switching units. Thus, there is provided a floor lock system for an operating table, which prevents the positioning of the table completely electro-mechanically by means of switching units without microprocessor monitoring, when the operating table is not locked to the floor in an emergency with security vulnerability of the operating table. In an embodiment of the present invention, the processor controls the state of the limit switches of the switching units under microprocessor control and allows positioning, if they are locked. In an emergency, when the table is not locked, unsafe positioning of the table is prevented by means of the limit switches without microprocessor monitoring. Furthermore, the control buttons are electrified when the switching units are in closed position. This allows the operating table to be positioned when it is locked.

[0014] A possible embodiment of the invention is characterized in that it comprises a locking button which is electrically connected to a table lock valve and the said switching units, and which is set to receive energy flow in both conditions, i.e. when the said lock mechanisms are locked to the floor and not locked to the floor. Thus, the operating table can be locked by a user via the locking button which is energized in all conditions where the lock mechanisms of the operating table are locked or not.

[0015] A possible embodiment of the invention is characterized in that it comprises an unlocking button, which is electrically connected to a table unlock valve and the said switching units, and which is set to receive energy flow in both conditions, i.e. when the said lock mechanisms are locked to the floor and not locked to the floor. Thus, the operating table can be unlocked by a user via the unlocking button which is energized in all conditions where the lock mechanisms of the operating table are locked or not.

The floor lock system (10) for an operating table is provided with a plurality of lock mechanisms (12) located on an operating table for locking the table. Figure 1 schematically shows the said lock mechanism (12). The floor lock system (10) of the present invention is provided with a first switching unit (14) as schematically shown in Figure 1, which is pressure-sensitive and closes when the control element emerging from at least three different free points on the lower part, in an embodiment of the invention emerging from three free corners out of four corners, of the table forms a plane by means of a plurality of pistons during the locking of the operating table. In addition, the floor lock system (10) of the present invention is provided with a second switching unit (16) as schematically shown in Figure 1 , which is pressure-sensitive and closes when the operating table is balanced on the floor plane by a piston emerging from at least one free point of the operating table where no other piston emerges, in an embodiment of the invention emerging from a free corner of the operating table where no other piston emerges. In an embodiment of the present invention, the switching units (14, 16) are limit switches. Furthermore, in the floor lock system (10) of the present invention, the said switching units (14, 16) are set to inform the microprocessor table control system about, the open or closed positions of the lock mechanisms (12) when the microprocessor table control system is activated and the closed positions of the lock mechanisms (12) are set to be detected and controlled by the table control system. In addition, in the floor lock system (10) of the present invention, the said switching units (14, 16) are set to be controlled by an electro-mechanical emergency control system when the electromechanical emergency control system is activated upon an emergency switch is manually switched to the closed position, and when the switching units (14, 16) are in closed position, one or more control button(s) (22) is / are set be energized through the switching units. The control buttons (22) are electrically connected to a plurality of control valves corresponding to the actuator control elements. In addition, the control buttons (22) are electrically connected to the said switching units (14, 16). In the present invention, there is also a locking button (18), which is set to receive energy flow in both conditions, i.e. when the said lock mechanisms (12) are locked to the floor and when not locked to the floor. The locking button (18) is electrically connected to a table lock valve and the said switching units (14, 16). Furthermore, in the present invention, there is also an unlocking button (20), which is electrically connected to a table unlock valve and the said switching units (14, 16). The unlocking button (20) refers to a button which is set to receive energy flow in both conditions, i.e. when the said lock mechanisms (12) are locked to the floor and not locked to the floor. By means of the floor lock system (10) of the present invention, when the table is locked, the switching units (14, 16) start transmission and the control buttons are energized, thereby actuating the movements. In this way, when the operating table is used for an emergency or when it is mobile, the positioning of the operating table is prevented on the floor lock system (10) and security is ensured.
