- the operation is the same as in the threaded nut-screw connection, in which a rotation of the screw causes a movement relative to the threaded nut in the axial direction.
- Actuation of the fastener by turning it clockwise from the side opposite the patient causes the piston-like member to be moved away from the patient, thereby building up tension in the leg.
- the rail 31 c is rotatable about the axis 71 c, wherein a lock by the combination of the present in the piston-like element 46 groove with the screw or the pin 44 is achieved with the through holes 42.

If the fastening part is rotated clockwise, it gradually approaches the slide rail until the protrusions 95 no longer permit further rotation due to the static friction. Thus, the movement of sliding of the sliding element is then prevented.
- the attachment part 91i has four or six handle devices 93i. This is illustrated in FIG. 10 in a side view and a front view, wherein only one embodiment with four handle devices is shown here. The handle devices are for ease of use of the attachment part.
- the fastening part is locked on the rail by a kind of clamping jaw, which is pressed by springs against the rail.
- an orthopedic table assembly 57, 59 is provided for hip surgery, comprising an operating table 59 with means 61 for horizontal sacral fixation of a patient P on one end of the table and a leg guide 57, wherein by means of the leg support 75, the distance of the leg 5 of the guide rail 31 is adjustable.
- the operating table 59 of the orthopedic table arrangement is arranged immovably to the leg guide 57.
- the leg guide is immovable to the operating table due to its own weight or due to a screw connection to the floor.
- the latching device 161 is fixedly connected at one end to the leg guide and has at the other end a clamp 163 which firmly fixes a column of the operating table by means of a stirrup 165.
- the operating table 59 of the orthopedic table arrangement has a height h 'from the bottom, for which applies: 80 cm ⁇ h' ⁇ 130 cm, wherein preferably: 90 cm ⁇ h 1 ⁇ 120 cm, more preferably that the height h the axis of rotation is substantially equal to the height h ' 1 of the hip joint 1, 3.
- the embodiments of the invention allow a comparison with the prior art simplified execution of a hip operation.
- a movement of body parts of the patient erfoderlich lowering the leg, swinging the foot and adduction of the leg
- a movement of body parts of the patient erfoderlich lowering the leg, swinging the foot and adduction of the leg
- a movement of body parts of the patient erfoderlich lowering the leg, swinging the foot and adduction of the leg
- only each simple sliding or pivoting movements are required so that a considerable Ver ⁇ simplification of the handle and thus a quick operation even with less practiced operating personnel is possible.
- the movement of the three steps is carried out automatically by a Steue ⁇ tion, which includes: actuators with angle sensors, sensor for detecting a tensile stress in the foot-fastening device, Program memory for the control of the Moto ren with reference to the recorded measured values, ⁇ memory for the specification of a time and angle-dependent desired curve for the tensile stress.
- a control device for hip surgery comprising an operating table 59 and a leg guide 57, further comprising at least one sensor for detecting a tension on the leg of the patient as well as suitably mounted and suitably coupled to the sensor actuators for the automatic movement of the leg in an operating position.
- the hip operation control device includes: at least two servomotors 111, 113 on the multi-axis hinge 17 for pivoting the foot 7, a servomotor 115 on the slider 29 for sliding the leg support 75 along the rail, and a servomotor 117 on the head element 37 for a rotation of the rail 31, at least one tension sensor 119 at least at the foot mounting device, a program memory 123, a data memory 125 for storing desired values for a time course of a tensile stress and ge measured values, a device for receiving an external storage medium 127th or a network connection 129, as well as a controller 121, which compares measured values of tensile stresses with the desired values on the basis of instructions stored in the program memory 123 and carries out a corresponding activation of the actuators 111, 113, 115, 117.
