Definitions
- the present invention relates to a seat for a surgeon's chair as he For example, it is used in surgery, particularly in the Microsurgery.
- Microsurgical operations in particular often take several hours It takes time during which the surgeon is extremely concentrated Must work. But also in medical practices such as an ear, nose and throat doctor or ophthalmologist, there are situations in which the doctor may look for a long time the treatment must remain in a sitting position. Any In such circumstances, physical inconvenience should arise be excluded, as these noticeably reduce the concentration can. Such a physical inconvenience can be seen in the fact that the Operator has to sit on the operator's chair for hours may only be covered with a cushion.
- a seat cushion is known, which is a large one Number of spaced apart elastic pins, some of which can be rounded off in a mushroom shape. Now a person sits on this Seat cushions, so these pens are dependent on the respective local Bend the surface pressure in one direction or the other. Depending on the hardness of the The material of the seat cushion and thus the pens become whole or partially bent. The person sitting on it becomes, so to speak sit freely swimming on the seat formed by the pins. This is not suited to the physical inconvenience of an operator during mitigate hours of surgery.
- a seat cushion is known from US Pat. No. 4,953,913, the interior of which is formed from the support surface forming, spaced apart pins, which supposed to be made of foam. It has to be assumed that these pins under the evasive movement described above Execute load. In any case, a contour-appropriate load function can do this Do not exercise the seat cushion.
- EP-A-0 300 243 is a medical one Document known to patients. This pad also has support elements elastic or partially elastic material. An application for the design of a Seat is not apparent from this document.
- the seat according to the invention is intended in particular in the Find microsurgery.
- the seat cushions according to the state of the Technology are completely unsuitable for this, since the seat cushions on which the The operator sits, so to speak, swimming freely, allowing smaller movements, which contradict the accuracy with which microsurgery intervenes have taken place.
- the invention is to be seen, whose task it is consists of specifying a seat of a surgeon's chair that - individually during adjustable assembly - offers a high level of seating comfort.
- a surgeon's chair that - individually during adjustable assembly - offers a high level of seating comfort.
- Such chairs usually only by a few People are used.
- a seat of an operator's chair is proposed, the seat of which is formed from a plurality of support elements arranged close to one another.
- the support elements are made of elastic or partially elastic material. She are supported in bores in a support part. The support elements point different heights and are distributed in this way on the seat arranged that this essentially the contours of the to be supported Body part, i.e. of the buttocks, follows.
- the carrier part has at least the seat partially bordering edge.
- the construction according to the invention allows the optimal seat contour for the prospective main user of the seat in one Color printing process can be determined. This works in a similar way Footprint process in orthopedic technology.
- a plate has on their underside. The expected user of the seat sits up on the plate, causing it to sit on an underlying one Paper sheet is pressed. The surface pressure gives a certain one Color samples, namely where the pressure is strongest, find one more intensive coloring instead of on areas with lower pressure.
- the seat contour of the seat according to the invention by equipping the carrier part with appropriate Support elements made.
- the shortest are found at the points of greater pressure Support elements, the longest support elements at the points of lowest pressure Application.
- the seating comfort of the support elements made from knob-like elements Seat is extremely high. Should one or more of the support elements damaged, they are easy to replace. For this, the base plate removed from the carrier part and the defective support elements simply after pushed out of the holes at the top and through a new one Support element replaced.
- the edge is designed that he partially surrounds the respective directly adjacent support elements for the purpose of stabilization.
- the support elements are preferably seated with a cylindrical constriction for support in the perforations and lie on the underside of the Carrier part with a substantially plate-shaped part.
- a support element For assembly or to replace a support element, this is a from above Drilled through introduced in the support part, its plate-shaped part elastic so deformed that it can be pressed through the bushing and finally pressed the support member into the through hole so that its cylindrical constriction comes to rest in the through hole.
- the cylindrical constriction has a length substantially that of Thickness of the carrier part corresponds. To push out a support element in the In the event of a repair, this can then be pushed upwards out of the drilled hole again, deforming the plate-shaped part.
- the support elements have one at the top rounded cylindrical shape. As a result, the seating comfort is still increased.
- Fig. 1 shows an embodiment of the seat according to the invention in supervision.
- the large number of support elements 1 to 12 arranged close to one another can be seen 8. These consist of elastic or partially elastic material. You sit in Bores 9 in a carrier part 10 (Fig. 2 to 4). In the illustrated In this exemplary embodiment, the support elements 1 to 8 are above the seat surface 11 arranged that this follows the contours of the buttocks, as shown in Fig. 2nd becomes clear.
- FIG. 1 This shows a sectional view along the axis of symmetry of the seat according to Fig. 1.
- the support elements 1 to 8 sit in Bores 9 in the carrier part 10. From below, the seat is by means of a Bottom plate 13 completed.
- the bottom plate 13 can, however, easily Carrier part 10 are removed, for example by loosening one Screw connection (not shown).
- the support elements 1 to 8 are in the present case of cylindrical shape and have an approximately cylindrical shape Constriction 14 on.
- the cylindrical constriction sits in the Perforations 9, d. H. it has a length about the strength of the Carrier part 10 corresponds.
- the support elements 1 to 8 are otherwise on the seat side rounded to increase the seating comfort.
- FIG. 3 shows the sectional view through the carrier part 10. It can be clearly seen here the edge 12, which in the present case does not completely surround the seat 11, but only in those places where there is no edge to kink the Support elements 1 to 8 could come under load.
- the carrier part 10 is - as shown in FIG. 4 - formed in one piece from one Workpiece, for example from a metallic casting. Is recognizable in remaining that the edge is designed so that it is the most immediate adjacent support elements partially bordered for the purpose of stabilization.
- Each seat can be individually adapted to the anatomical conditions of the likely main user of the seat are manufactured accordingly.
- the color impression process already mentioned at the beginning serves this purpose.
- Whose Result is transferred to the seat by using the support part accordingly
- Support elements (1-8) is equipped. In places found high Surface pressure becomes small (low) support elements, in places of one low surface pressure correspondingly high (long) support elements in the Perforations set.
- the seat according to the invention compared to conventional seats an enormous gain in seating comfort for the surgeon.
- the reason for this is in the almost constant size ratios of pools See pelvis even if the connective tissue, muscles, etc. are completely cause different appearance.
- Crucial for seating comfort but is primarily the bony skeleton.
