1 shows a medical coupling device according to the invention 100 for connecting a medical holding device 200 with or on a patient support 300 in a perspective view.

The medical coupling device 100 is referred to below for simplicity as a coupling device 100 and the medical holding device 200 simplifying as a holding device 200 .

The coupling device 100 comprises in this embodiment at least one first adjustment section 1 , here as an example as the first setting plate 1 is configured, a second adjustment section 3 , here as an example as a second setting plate 3 is designed, a first swivel joint 5 , an adapter 7th , a second swivel joint 9 and a fastening device 11 .

These components are described further in relation to the following figures. With regard to the in 1 through opening shown 39 will be on their discussion too 4th referenced.

2 shows a section of the 1 , which the fastening device 11 for connecting the coupling device 100 with the patient support 300 includes.

The fastening device 11 is optional here by means of z. B. four screws 13th , roughly from below, in terms of the arrangement of the 2 , to the patient rest 300 screwed on. The four screws are purely exemplary 13th designed as countersunk screws so that screw heads do not go over the surface of the fastening device 11 survives. Ideally, this remains smooth or even. This is advantageous in order to be able to easily clean or disinfect the surfaces, for example.

The second swivel joint 9 allows the second adjustment plate 3 relative to the patient support 300 to twist or pivot. As the second adjustment plate 3 and the first adjustment plate 1 according to the invention are displaceable relative to one another along or in each case parallel to a plane, and there between the first adjusting plate 1 and the holding device 200 the first swivel joint 5 is arranged, the coupling device 100 advantageously rotated and shifted and at the same time the holding device 200 unchanged parallel or at a different angle relative to the patient support 300 be carried.

3a shows a first positioning of the first adjustment plate 1 and the second adjustment plate 3 the coupling device according to the invention 100 .

The two adjustment plates 1 , 3 are mutually displaceable in an xz plane, i.e. in a plane that is perpendicular to the plane of the drawing (see also 6th ).

Furthermore, the adapter 7th against the first adjustment plate 1 rotatable about the z-axis (or an axis parallel to the z-axis), which is perpendicular to the plane of the drawing. The first swivel joint 5 and the second swivel joint 9 are in. for the sake of clarity 3a not shown, only by means of their reference numerals 5 , 9 indicated.

There is also a second adjustment plate 3 around the z-axis against the fastening device 11 or rotatable or pivotable relative to this.

Based on the two rotation options mentioned, it is possible that the longitudinal axis of the adapter 7th as well as the fastening device 11 can be shifted and moved and - should this be desired - run unchanged, for example parallel to one another and / or unchanged in a common plane. This is particularly advantageous when a holding device 200 such as a surgical head restraint device 201 should optionally be set vertically or at another preferred angle that is desired or necessary for the respective medical application. Thus, for a surgeon, for example, during an operation it is on Head particularly easy, one in the head holder 201 fixed skull in a desired position relative to the patient support 300 on which the head holder 201 by means of the coupling device according to the invention 100 is attached. This can be both the aforementioned angle and the distance between the head holding device 201 and patient support 300 affect.

The coupling device according to the invention 100 can of course also offer this advantage based on the aforementioned possibilities of movement in other medical applications, for example in diagnostics or in patient monitoring by means of monitors connected to the holding device 200 can be connected.

3b shows a second positioning of the first adjustment plate 1 and the second adjustment plate 3 relative to the fastening device 11 and / or to the longitudinal axis of the adapter 7th the coupling device according to the invention 100 . The above description of the 3a applies here analogously.

It can be seen that a right in 3a and 3b to be recognized, optional star wreath in both figures at the same angle to the vertical and / or at the same angle to a surface of the patient support 300 stands. This is ultimately due to the provision of the two swivel joints, namely the first swivel joint 5 and the second swivel joint 9 whose angles of rotation can be set independently of one another.

4th shows an embodiment of the coupling device 100 with a device for fixing the first adjustment plate 1 with the second adjustment plate 3 . This device has, for example, a screw or a bolt 15th with a bolt head 21 on. The bolt 15th can e.g. B. a thread 27 and with an optional locking nut 17th that are on the thread 27 of the bolt 15th can be screwed on, be secured.

An optional handle 19th can be used to manually lock or loosen the locking nut 17th the screw connection be provided.

Instead of the one with the handle 19th provided locking nut 17th can the locking nut 17th be designed as a standard part, for example as a hexagon nut, or in another form.

Between the first adjustment plate 1 and the second adjustment plate 3 can be a preferably elastic element, here in the form of an O-ring 25th , be provided, which reduces the friction between the two adjustment plates 1 , 3 can increase and improve the positioning accuracy. It can also protect against unintentional loosening of the two by means of bolts 15th and locking nut 17th screwed or jammed adjustment plates 1 , 3 Offer.

The entire arrangement of the bolt 15th , the thread 27 , the O-ring 25th , the washer 23 and the locking nut 17th with the handle 19th can be used as a locking device 28 are designated. The locking device 28 can consist of other elements than those mentioned here, or have such elements in addition or as an alternative.

For example, instead of the locking nut 17th A locking screw can be used that fits into an optional internal thread of the bolt 15th can be screwed in.

The bolt head 21 here optionally has a rectangular shape in plan view, it can have rounded corners as here (see 1 and 6th ). The - apart from the corners - rectangular shape of the bolt head 21 is in the longitudinal direction of the bolt 15th at least partially in a corresponding recess or groove in the first setting plate 1 inserted. Bolt head 21 and the associated recess can form a form fit that allows rotation of the bolt 15th around its longitudinal axis when tightening the locking nut 17th can prevent.

Between the locking nut 17th and the second adjustment plate 3 is an optional spacer 23 arranged. The intermediate disk 23 can be referred to here as a washer. The intermediate disk 23 can tighten the locking nut 17th facilitate by tightening the torque on the locking nut 17th is transferred to a smaller area compared to the large friction surface between the washer 23 and the second adjustment plate 3 .

4th further shows the first swivel joint 5 as a connecting joint of the first adjustment plate 1 to the adapter 7th as well as the second swivel joint 9 as a connecting joint of the second adjustment plate 1 to the fastening device 11 .

The second adjustment plate 3 has a through opening or bore 39 on in which the bolt 15th is arranged radially (and optionally also axially) displaceably. The opening area of the bore is - in optionally two spatial directions - larger than the cross section of the bolt 15th which is why the latter when he goes into the hole 39 is inserted, can be moved laterally within this. In 4th corresponds to the plane within which the bolt 15th is laterally movable, a spanned in the xz plane or a plane parallel to this.

The hole 39 is also in 1 in the perspective view and in 6th visible in the top view and can be through the can easily be assigned to different perspectives.

The one with the bolt 15th first adjusting plate connected as described above 1 can, together with an optionally adapted holding device 200 attached by means of the adapter 7th on the first swivel joint 5 , parallel to the second adjustment plate 3 be moved as far as the hole 39 lateral movement of the bolt 15th allows. In the example shown here, the mobility is limited solely by the diameter 41 the purely exemplary circular hole 39 and the outside diameter of the bolt 15th in that section of the bolt 15th with which he was in the hole 39 is arranged. The bolt is within this limit 15th , and thus also the first adjustment plate 1 , in this embodiment freely movable in an xz plane.

In the following, a purely exemplary numerical example is given to illustrate the displaceability of the first adjustment plate 1 to clarify. Depending on the shape and size of the hole 39 , especially depending on their diameter 41 , this displaceability changes in the xz plane. It can be shown differently than here if, for example, the bore has an oval shape or any other shape.

The diameter can be purely exemplary 41 the hole 39 65 mm and the outside diameter of the bolt 15th 20 mm. This results in the first adjustment plate being displaceable 1 relative to the second adjustment plate 3 of approx. 45 mm in the x direction and of approx. 45 mm in the z direction. The first adjustment plate is within these limits 1 in this example freely movable in the bore 39 .

The hole 39 can be used as a through opening 39 are designated.

5a shows the second swivel joint 9 the coupling device according to the invention 100 in a locked state.

The locked state is due to the meshing of toothed elements 29 (e.g. ring gear, starburst, claws, or the like). The gear elements 29 are optional as two star-shaped teeth 29 designed. The star-shaped toothing 29 can be referred to as so-called Hirth teeth.

The teeth 29 can optionally with the help of a rotary knob 31 locked and released again. The knob 31 is optional as a hand knob 31 designed. With the help of the rotary knob 31 can be half of the star-shaped toothing 29 to the right, based on the view in 5a to be moved. This shifting is done by means of a thread 33 realized that on a section of the second swivel joint 9 , for example a spindle, is arranged. When the knob 31 is rotated, the thread shifts to the right, so that the star-shaped toothing 29 no longer interlocks. This is in 5b shown.
