Description

[0001] The invention relates to a cushion element for an operating table and to an operating table.

[0002] EP 1 785 124 B1 discloses a cushioning element for an operating table. It is constructed in two parts from different materials and, when assembled, forms a cuboid-shaped cushioning body. Several cushioning elements can be arranged next to one another on a lying surface of an operating table, thus enabling a soft support for the patient. However, it is desirable not only for the patient to lie comfortably, but also for the surgeon to have access to the part of the patient's body that is to be operated on.

[0003] The object of the present invention is therefore to further develop a cushioning element and to provide an operating table in such a way that a comfortable and soft positioning of the patient on the one hand and accessibility to a body part of the patient to be operated on on the other hand is ensured, wherein the cushioning element is easy to handle and easy to clean.

[0004] To achieve this object, the invention has the features of claim 1.

[0005] The particular advantage of the invention is that opposing side cutouts form a central taper in a central section of the cushion element, so that when a patient is lying on the cushion element, the surgeon has easier access to the patient's body parts to be operated on from two opposite sides. A flat base surface of the cushion element ensures secure support of the cushion element on the operating table. Since the side cutouts are arranged on opposite sides, the cushion element can also be rotated 180° on the operating table without compromising the surgeon's access to the body part to be operated on.

[0006] According to a preferred embodiment of the invention, the cushioning element is designed as a torso cushioning element that serves to support the shoulder, back, and pelvic areas of the patient. The torso cushioning element is preferably arranged between a head cushioning element and a leg cushioning element. The first cushioning section of the torso cushioning element is designed as a shoulder section, and the second cushioning section as a pelvic section, whereby both the shoulder area and the buttock area of ​​the patient are adapted to the width of the operating table, thus ensuring secure support for the lying patient.Only in the central area, where the patient's back rests, is the torso cushion element narrower than the operating table due to the side cutouts. Thus, the width of the cushion element in the patient's back area corresponds to the width of the patient lying on their back. This allows the surgeon to access the patient's organs, such as the kidneys, not only from the side but also easily from below. This can advantageously facilitate an invasive procedure for removing kidney stones.

[0007] According to a further development of the invention, the central region of the cushioning element has a beveled edge surface extending diagonally downwards from a cover surface forming the upper side of the cushioning element. This advantageously creates an enlarged lateral space, which facilitates the handling of the surgical instrument by the surgeon.

[0008] According to a further development of the invention, the shoulder section and / or the pelvic section of the cushioning element each have a beveled edge surface on facing sides, which extends diagonally downward from the top surface of the cushioning element. This further increases the range of motion on the patient's side for the surgeon to manipulate his or her surgical instrument without compromising the stability of the cushioning element.

[0009] According to a further development of the invention, the cushioning element is designed in a double T-shape, thus providing a stable basic shape. The edges of the cushioning element are essentially straight.

[0010] According to a further development of the invention, the beveled edge surfaces of the pelvic section are larger than the edge surfaces of the shoulder section. In particular, a lower corner of the edge surface of the pelvic section extends toward the floor surface at a height that is less than half the height of the cushion element. This facilitates access, in particular, to the patient's lower spinal region, where the kidneys are located.

[0011] According to a further development of the invention, the pelvic section has a central recess on a side opposite the shoulder section, i.e., a rear end of the cushion element, so that the patient's buttocks area can be positioned at a lower level than the back area. This makes positioning the patient lying on their back more comfortable.

[0012] To solve the problem, the operating table has the features of claim 14.

[0013] Advantageously, the patient can be safely positioned by means of a head cushion element, a leg cushion element and a torso cushion element arranged between them, wherein side recesses in the torso cushion element facilitate easier access to organs arranged laterally or laterally at the rear, such as the kidneys.

[0014] Embodiments of the invention are explained in more detail below with reference to the drawings.

[0015] They show: Fig. 1 a perspective view of an upholstery element according to the invention seen from behind, Fig. 2 a side view of an operating table with a patient lying on several upholstered elements of the operating table, wherein a head cushion element, a torso cushion element and a leg cushion element are arranged on the operating table, Fig. 3 a top view of the operating table with the patient lying on his back, Fig. 4 a top view of the upholstery element, Fig. 5 a bottom view of the upholstery element, Fig. 6 a side view of the upholstery element and Fig. 7 a rear view of the upholstery element.

[0016] A cushion element 1 according to the invention is provided for resting on a lying surface 2 of an operating table 3, so that a patient 4 is partially supported.

[0017] In the present embodiment, a head cushion element 5 for supporting a head 6 of the patient 4, a leg cushion element 7 for supporting legs 8 and feet 9 of the patient 4, and the cushion element 1 arranged between the head cushion element 5 and the leg cushion element 7 are arranged on the lying surface 2 of the operating table 3. The cushion element 1 is designed as a torso cushion element and serves to support a torso 10 of the patient 4. As can be seen from Fig. As can be seen in Figure 2, the torso cushion element 1 has an upper cover surface 11, on which the torso 1.0 of the patient 4 rests directly. Furthermore, the torso cushion element 1 has a base surface 12 running parallel to the cover surface 11, which is in direct contact with the lying surface 2 of the operating table 3. Narrow surfaces 45 are arranged between the cover surface 11 and the base surface 12, connecting the cover surface 11 to the base surface 12.

[0018] As is particularly evident from Fig. As can be seen in Figure 4, the cushioning element (torso cushioning element 1) is double-T-shaped in plan view (double-T form). It has a wide shoulder section 13 and a wide pelvic section 14, between which a comparatively narrow central section 15 is arranged in one piece. The shoulder section 13 has a first end face 16 of the cushioning element 1, which lies flat against the head cushioning element 5. The pelvic section 14 has an end face 17 of the cushioning element 1, which lies flat against the leg cushioning element 7. The cover surface 11 extends at the same height as a cover surface of the leg cushioning element 7.

[0019] The head cushion element 5 has a cover surface which is higher, i.e. arranged at a greater distance from the lying surface 2, than the cover surface 11 of the torso cushion element 1. The head 6 of the patient 4 is thus at a higher level than the rest of the patient's body.

[0020] The cushion element 1 has side cutouts 18 on opposite sides, so that the cushion element 1 is not cuboid-shaped, but rather tapered in a central region. The cushion element 1 thus has a first cushion element section formed by the shoulder section 13 and a second cushion element section formed by the pelvic section 14, which are connected to one another via the central section 15. The central section 15 has the side cutouts 18 on the sides.

[0021] A width b M of the central section 15 is thus smaller than a width b S of the shoulder section 13 and smaller than a width b B of the pelvic section 14. The width b S of the shoulder section 13 and the width b B of the basin section 14 essentially corresponds to a width b L the lying surface 2 of the operating table 3. The width b Mof the central section 15 essentially corresponds to a width b P of the patient 4.

[0022] To improve the surgeon's access to the organs of the supine patient 4, for example, access to the kidneys for the purpose of removing kidney stones, the cushion element 1 additionally has beveled edge surfaces. Firstly, the central section 15 has a beveled edge surface 19 that connects the cover surface 11 of the central section 15 to an upright side surface 20 (part of the narrow surface 45) of the central section 15. The beveled edge surface 19 can, for example, have an angle in the range of 35° to 65° with respect to the cover surface 11.

[0023] Furthermore, second beveled edge surfaces 21 are provided, with each beveled edge surface 21 extending laterally from the top surface 11 of the basin section 14 in the direction of an upright indentation surface 22 and an upright side surface 23 of the basin section 14. The indentation surface 22 runs perpendicular to the side surface 20 of the central section 15 and directly adjoins it. The edge surface 21 is triangular in shape, with a lower corner 24 spaced from the top surface 11 having a vertical distance a from the top surface 11 that is greater than half a height h. P of the upholstery element 1.

[0024] In the present embodiment, this distance a corresponds to a depth of the respective side recesses 18, so the width b B of the basin section 14 of a sum of the width b M of the central section 15 and twice the distance a.

[0025] Furthermore, in the present embodiment, the distance a corresponds to a distance from a first upper corner 26 of the edge surface 21 in the longitudinal direction L of the cushion element 1 to an imaginary straight line which is perpendicular to a longitudinal center plane M L of the upholstery element 1, wherein the imaginary straight line intersects a second upper corner 25 of the upholstery element 1.

[0026] A third edge surface 27 is formed on both sides of the shoulder portion 13, the third edge surface 27 extending from the cover surface 11 to a recessed surface 28 of the shoulder portion 13 and to a side surface 29 thereof. A corner 30 connecting the recessed surface 28 and the side surface 29 has a perpendicular distance b from the cover surface 11 that is less than half a height h. P of the upholstery element 1.

[0027] The triangular edge surfaces 19, 21, 27 are each flat and slope down from the cover surface 11 in an angular range between 35° and 65°, preferably 45°.

[0028] The edge surfaces 21 of the basin section 14 have an edge 40 adjoining the cover surface 11, which is aligned with the longitudinal center plane M L forms an angle bisector. The first upper corner 26 and the second upper corner 25 are located at opposite ends of the edge 40.

[0029] The edge surfaces 27 of the shoulder section 13 have an edge 41 adjoining the cover surface 11, which is aligned with the longitudinal center plane M L forms an angle bisector. A first upper corner 35 and a second upper corner 36 are arranged at opposite ends of the edge 41.

[0030] The cushion element 1 is symmetrical with respect to the longitudinal center plane M L trained.

[0031] The pelvic section 14 has a central recess 31 on a side facing away from the shoulder section 13 or the central section 15. This recess 31 is symmetrical to the longitudinal center plane M L The recess 31 is partially circular in plan view of the cushion element 1 with a maximum depth t A at the longitudinal center plane M L . The depth t A is greater than 1 / 3 of a length I B of the pelvic section 14 running in the longitudinal direction L of the cushion element 1.

[0032] As can be seen in particular from the Fig. 4 and Fig. 5, a length I M of the middle section 15 greater than a length l S of the shoulder section 13 or a length l B of the basin section 14.

[0033] Furthermore, the cushion element 1 has longitudinal recesses 32 on the base surface 12, which extend only along the edges of the shoulder section 13 and the pelvic section 14 in the longitudinal direction L. In this way, the cushion element 1 can interact with elevations of the lying surface 2, so that the cover surface 11 runs flat and horizontally in the mounted position of the cushion element 1 on the lying surface 2 of the operating table 3. A central region 33 of the base surface 12 has a sufficiently large support surface, ensuring the stability of the cushion element 1 on the lying surface 2 of the operating table 3.

[0034] The cushioning element 1 is preferably formed in one piece and consists of a foam material which is surrounded by a textile or plastic cover. QUOTES CONTAINED IN THE DESCRIPTION
