Definitions

  • the invention relates to a system according to the preamble of claim 1.
  • Such a system is known e.g. from the publication "Clinac 6/100” from Varian (RAD 1826 A 2/79).
  • the spatially movable device to be controlled there consists of a linac and a treatment bed.
  • a hand unit belonging to the system is shown.
  • it has the disadvantage that it can only be operated with both hands. The patient can therefore not be cared for while setting the Linac or the treatment bed.
  • a system for controlling a therapy device and a treatment bed is known from the publication "Therasim 720" from AECL (Med. 54 3/72), in which a hand unit, an input point and an electronic process control unit are shown.
  • the hand unit can only be operated with both hands.
  • buttons on the control unit can be blocked accidentally or deliberately. In the case of operating units without a dead man function, this can have serious consequences for the patient, especially in systems without touch protection, in which e.g. when the spotlight head is touched, all parameter changes are interrupted immediately.
  • the invention is therefore based on the object of designing a system of the type mentioned at the outset in such a way that the hand unit can be operated with one hand, fulfills the dead man's requirement and all desired parameter values can be read directly on a monitor in large display.
  • the advantages achieved by the invention are essentially to be seen in the fact that the operator can work in the entire room and still has one hand free, for example in order to be able to set up the patient in a system with a therapy device and treatment bed.
  • the dead man requirement is fully guaranteed and is the right one of the set parameter values in the entire room can be checked immediately on the monitor.
  • the invention is also well applicable to spatially movable devices of another type, such as e.g. for hoists, especially cranes, and machine tools. With the invention, some sources of danger are also eliminated here, e.g. when loading trucks with a crane.
  • a system for controlling the position parameters e, oe, r, s, q, v of the spatially movable device 1 is shown in the figures. In its basic structure, it consists of a hand-held unit 2, an electronic process control unit 5 with an input point 6, a monitor 8 and an OR gate 12.
  • the spatial positions of the device 1, here a betatron with a radiator head and treatment bed are characterized by the position parameters e, ⁇ , r, s, q, v.
  • the position parameters e, ⁇ , r designate the positions of the spotlight head of the betatron.
  • the position parameter e determines the movement of the lamp head in the longitudinal direction of the treatment bed
  • the position parameter ⁇ the angle of rotation of the lamp head about the isocentric axis
  • the position parameter r the movement in the beam direction of the lamp head.
  • the position parameters s, q, v characterize the positions of the treatment bed.
  • the position parameter s determines the position in the longitudinal direction
  • the position parameter q the position in the transverse direction
  • the position parameter v the position in the vertical direction of the treatment bed.
  • the position parameters e, ⁇ , r, s, q, v are set with the actuators 7a - 7f of the device 1.
  • the hand-held unit 2 has parameter selection keys 3a - 3f, keys for additional functions 9a - 9f, a slide 4, which is held in a stable, idle position 0 by means of a spring, an emergency switch 10 and signal lamps III-III. It is operated by a hand 18 with the index finger 13, middle finger 14, ring finger 15, little finger 16 and thumb 17 of the operator.
  • the process control unit can e.g. a microcomputer, type HLF from Indel, D Wegner (Switzerland).
  • the entry point is e.g. a device of the brand Maxiswitch Comp.
  • the monitor is from the brand RCA type TC 1214 ..
  • Pressing the 3a key displays the parameter value e, ie the position of the lamp head in the longitudinal direction, on the monitor 8. If the If the slide 4 is actuated in the direction a, for example, the lamp head is moved forwards in the longitudinal direction of the treatment bed by means of the actuator 7a. The value of the deflection of the slide 4 from the rest position 0 determines the speed of the parameter change. In this case there are two discrete steps in the forward direction and two in the backward direction. A continuous deflection of the slide 4, and thus a continuous control of the speed of the parameter change, can also be carried out.
  • the parameter change takes place in the reverse direction when the slide 4 is pushed in direction b.
  • the process control unit 5 is programmed such that when two parameter selection keys 3a - 3f are pressed simultaneously, only one signal is taken into account, i.e. that only a single parameter change is made. This applies analogously to several keys 3a - 3f pressed simultaneously or additional function keys 9b, 9e and 9f.
  • the opening of the diaphragm of the spotlight head can be enlarged or reduced in width (x direction) and length (y direction).
  • the key 9b together with the slider 4 allows the spotlight head to be turned away from the isocentric axis.
  • the parameter selection key 3a and the key 9c automatically adjust the parameter position, here the longitudinal direction e of the spotlight head (setpoint).
  • the lamp llg or llh indicates in which direction the parameter change takes place.
  • the lamps lla and llk light up.
  • the entire device 1 is brought into the starting position by pressing the two buttons 9c and 9d.
  • lamps llk and 11C light up, this home position has been reached.
  • the lamp lli lights up when the spotlight head is touched.
  • the current parameter changes are then automatically interrupted by the blocking system of the process control unit 5.
  • the blocking can be bridged with the button 9a, so that further parameter changes can be made deliberately.
