Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The detailed description particularly refers to the accompanying figures in which:

(2) FIG. 1 shows a system according to an embodiment of the present disclosure; and

(3) FIG. 2 shows a flowchart illustrating a method according to the present disclosure.

DETAILED DESCRIPTION

(4) FIG. 1 shows a system 1 according to an embodiment of the present disclosure. The system 1 comprises an operating table 2, an air bladder 3, and an air compressor 4.

(5) The operating table 2 comprises a tabletop 5 including several sections. Amongst others, in this embodiment, the tabletop 5 includes a back section 6 and a seat section 7 which are formed as respectively including an upper deformable portion 8 and a lower rigid portion 9.

(6) The upper deformable portion 8 of the seat section 7 is formed by a first layer of a split pad 15 and the lower rigid portion 9 is formed by a second layer of the split pad 15. The upper first and the second layer are joined to each other in a portion at a defined end of the split pad 15. Alternatively, the layers of the split pad 15 are not joined to each other. The first layer and the second layer respectively comprise different structures for respectively having a different stiffness. Alternatively, the first layer and the second layer have a same structure and the stiffness of the lower rigid portion 9 is caused by a rigid plate to which the second layer of the split pad 15 is attached. As a further alternative, the upper deformable portion 8 is formed by a bolster of the tabletop 5 and the lower rigid portion 9 is formed by a rigid plate-shaped component of the seat section of the tabletop 5. In this embodiment, the split pad 15 is formed so as to cover a face of one of the sections of the tabletop 5, however, in alternative embodiments, one split pad 15 or one bolster as the upper deformable portion 8 can cover several sections or the entire face of the tabletop 5. Optionally, the plate-shaped component can be made of a radiolucent material.

(7) The air bladder 3 is inflatable by the air compressor 4. The system 1 comprises a control panel 10 configured to control an air pressure in the air bladder 3. The control panel 10 comprises operating elements for inflating air pressure into the air bladder 3 and for releasing the air pressure from the air bladder 3. Alternatively, the operating elements enable a setting of the air pressure in the air bladder 3. The operating elements operate a controller 13 which is included in the control panel 10 or, alternatively, in the compressor 4. The compressor 4 comprises a pressure sensor 12. The pressure sensor 12 detects air pressure in the air bladder 3 and the controller 13 controlling the air compressor 4 processes the detected air pressure to provide a constant air pressure set at the control panel 10. The controller 13 is an electronic controller, however, in an alternative embodiment, the controller is a pneumatic controller. Alternatively, the pressure sensor 12 is not provided and the air pressure in the air bladder is adjusted manually.

(8) The sections of the tabletop 5, in particular, the back section 6 and the seat section 7 are linked by a joint 11. In this embodiment, also the remaining sections are respectively linked by the joints 11, however, in an alternative embodiment, not all of the sections are linked by the joints 11 but they are rigidly linked.

(9) The system 1 hosts the air bladder 3 between the upper deformable portion 8 and the lower rigid portion 9 of the tabletop 5. The air bladder 3 is movable when being hosted between the upper deformable portion 8 and the lower rigid portion 9, in particular, the air bladder 3 is movable into a position adjacent to one of the joints 11. Furthermore, in particular, the air bladder 3 is movable into a position adjacent to the joint 11 linking the back section 6 and the seat section 7. In the shown position, in connection with the joints 11, the tabletop 5 is configured to provide a position of a patient's body (not shown) suitable for a kidney surgery when the patient's body is placed on the tabletop 5 as usual.

(10) The system 1 further comprises a foam pad 14 positioned between the air bladder 3 and a patient's body (not shown). Alternatively, the foam pad 14 is not provided.

(11) FIG. 2 shows a flowchart illustrating a method according to the present disclosure. In use, in step S1, the air pressure is inflated by the air compressor 4 into the air bladder 3 hosted in the tabletop 5 and, thereby, the upper deformable portion 8 of the tabletop 5 is deformed. The upper deformable portion 8 is upwardly bent by the air bladder 3 so as to provide a shape of the surface of the tabletop 3 to generate a flexed position of the patient's body. In step S2, the air pressure in the air bladder 3 and, in step S3, a position of the airbladder 3 are adjusted such that a requested position of a patient's body is achieved by the deformation of the upper deformable portion 8. Therefore, the air bladder 3 is moved between the upper deformable portion 8 and the lower rigid portion 9 into a suitable position. The sequence of adjusting the air pressure and the position is not fix and it also can be an iterative process. In case of a kidney surgery, the suitable position is close to the joint 11 between the back section 6 and the seat section 7. Thereby, the flexed position of the patient's body suitable for kidney surgery is provided. Alternatively, the air bladder 3 is already in a suitable position for a planned surgery so that adjustment thereof is not necessary. Furthermore, alternatively, the suitable position is not close to the joint 11 between the back section 6 and the seat section 7 but at another suitable location.

(12) In step 4, the air pressure is actively maintained constant during a requested period by the air compressor 4. The detected air pressure in the air bladder 3 is processed by the controller and the air pressure is adjusted by the air compressor 4. In particular, during the surgical intervention when the surgeon operates in a wound of the patient's body, a constant position of the body is important in order not to injure the patient. Alternatively, an actively maintained constant air pressure is not necessary since. e.g., the system of the compressor 4 and the air bladder 3 is tight enough for passively maintaining the air pressure in a suitable manner.

(13) The air pressure is varied in step S5 for changing the position of the patient's body according to a modified request. In the course of a surgery, e.g. a modified position of the patient's body can be necessary. Hence, the air pressure in the air bladder 3 is varied. Alternatively, the air pressure is maintained constant during the entire surgery and released when the surgical intervention is finished.

The invention is not limited to the disclosed embodiments. From reading the present disclosure, other modifications will be apparent to a person skilled in the art.
