Distractors are employed in surgery, where it is necessary to change the separation between two parts of the spinal parts, in particular, to increase the separation. A vertebral distractor has the task of increasing the separation of two vertebrae, in particular during an operational procedure in the area of the vertebral disks. A distractor is essentially comprised of two pliers-shaped link elements, with grip parts and with engagement parts in the form of jaws. If the engagement parts can be changed out, they are referred to as �valves�. The valves are in operating engagement with the grip elements. For spreading apart two vertebra of the spinal column, the distractor with the two valves is introduced between the vertebra to be spread apart. Spreading occurs by operation of the grip elements. The degree of spreading between the valves can be set by an adjustment element.
SUMMARY OF THE INVENTION The present invention is thus concerned with the task of providing a distractor of the above-described type, in which the valves are exchangeable in simple mode and manner.
BRIEF DESCRIPTION OF THE DRAWING The invention will now be described in greater detail on the basis of the embodiment represented schematically in the figures. There is shown:
DETAILED DESCRIPTION OF THE INVENTION FIG. 1 a shows a vertebral distractor 01 comprised of a first link part 02, which is pivotably connected with a second link part 03. The pivotably linkage between the first link part 02 and the second link part 03 is achieved by a connecting pin 04, which at the same time defines the axis of rotation 04. The first link part 02 is provided with a pliers element 05 as well as a grip element 06. The second link element is provided with a pliers element 07 as well as a grip part 08. With reference to the axis of rotation 04 defined by the connecting pin 04 between the two linkage parts 02 and 03, the grip elements 06, 08 are provided on a first side. With reference to the axis of rotation defined by the connecting pin 04, the pliers elements 05, 07 are provided on a second side lying opposite to the first side. The pliers element 05 is in operative association with the grip part 06 via the first link part 02. The pliers element 07 is operatively associated with the grip element 08 via the second link part 03. On the two free axial ends of the pliers elements 05, 07 there are provided recesses 09, 10. In the recesses 09 and 10 there is respectively insertable one engagement element 11 of a valve 12. Each valve is comprised of an engagement element 11 and a jaw 13. The valve 12 is releasably securable on the respective pliers element 05, 07 via a securing mechanism of the first type (for reasons of better oversight, the securing mechanism of the first type is separately shown in FIG. 2 and thus the details of the securing mechanism of the first type are not shown in FIG. 1). For releasing the securing mechanism between valve 12 and pliers elements 05, 07 there is provided in the present illustrative embodiment, in the area of the axial end of the pliers element 05, 07, a push button of the first type 14. By operating the push button of the first type 14 the connection between valve 12 and consequently pliers element 05, 07 can be released.
