Definitions

  • ABSTRACT A device for obtaining a desired, substantially constant, adjustable force in a wire especially for surgical tensioning treatment of patients having injuries in their skeleton and/or soft parts, the device comprising a container divided into two chambers, one chamber thereof being evacuated to a predetermined subatmospheric pressure and the other chamber thereof being in communication with the atmosphere, said two chambers being separated from each other by a piston connected to the wire, and by a sealing means, preferably a roll membrane.
  • the present invention relates in general to a device for clinical tensioning treatment of injuries in the skeleton and soft parts of the human body. Such a treatment is intended to restore and maintain the injured parts in a desired position.
  • the force from the tensioning device is often transferred to the intended skeleton member by a thin wire, a so called piano wire, which is thread through the bone and strongly tensioned between the arms of a U-formed yoke.
  • the present invention reduces the acceleration forces to neglectable values.
  • the patient will be less difficult to take care of and will require fewer number of nursing hours for his care.
  • a possibility is given to transport the patient between e.g. nursing departments without the need to interrupt the tensioning treatment during the transport.
  • the advantages obtained by the present invention from the nursing point of view are considered to result in smaller nursing costs.
  • Attempts have been made to solve the problem with the acceleration forces.
  • comprising springs has the drawback that it generates different forces when the wire moves and sufficiently levelled springs are very space consuming.
  • FIGURE is a schematic illustration of the presently preferred embodiment of the invention which shows the members of the assembly, their structural nature and their cooperation.
  • the constant force is generated by the fact that the atmospheric pressure is allowed to act upon a piston 1, one side thereof being provided with an evacuated space 2. By doing so the piston rod 3 will always generate the same force irrespective of the position of the piston.
  • the chamber 5 is connected to the atmosphere.
  • the piston 1 and the piston rod 3 may be made to have a very low weight which means that the effect of the acceleration forces can be neglected.
  • a roll membrane 4 In order to seal the piston 21 membrane is used, preferably a roll membrane 4.
  • the cylinder 6 is pivotally mounted at 7 to the holder or support frame 8.
  • the piston rod 3 is at 9 movably mounted to the lever 10, which is mounted to the holder by a pivot joint at 11.
  • the tensioning device is here illustrated to be a wire 12 which is attached to the lever 10 at the point 13 and runs or extends over pulleys 14 and 15.
  • the attachment point 9 can be moved between 11 and 13 and it is hence possible to obtain a tension in the wire 12, which tension can have the desired value between zero and the force of the piston rod 3.
  • the position of the pulley 14 can be selected along the indicated line A-B so that the wire 12 and the piston rod 3 are substantially parallel during the movement of the lever 10 irrespective of the position of the point 9 between 11 and 13. Thus, variations due to the ratio are mini mized during the spring movement.
  • the space 2 is evacuated through the outlet 16, which can be sealed.
  • a vacuum meter 17 is preferably also connected to the space 2.
  • the lever 10 may be extended through the holder 8 and the device 3 effecting the tensioning force may be situated above the lever 10 on the opposite side of the holder 8.
  • Apparatus for providing a desired, substantially constant adjustable force at the point of attachment to the patient of a tensioning device for the surgical tensioning treatment of patients having injuries to their skeleton and/or soft parts so that the force remains independent of the position of the attachment point, movements of the patient and/or other acceleration forces comprising in combination:
  • a tensioning device having one end thereof attachable to a patient
  • means for providing a constant tensioning force without the aid of an external power source including a cylinder divided into two chambers, one chamber thereof being evacuated to a predetermined subatmospheric pressure and the other chamber thereof being in communication with the atmosphere, a piston and a sealing means mounted within said cylinder and separating said two chambers from each other, and a piston rod connected to said piston; and, an adjustable force changing means for connecting said piston rod to said tensioning means and for adjusting the force supplied to said tensioning means to the desired constant value.
  • sealing means is a roll membrane.
  • said adjustable force changing means is a pivotable lever, and said piston rod is movably connected to said lever.
  • said wire guiding means is adjustable in order to change the ori entation of the medium direction of the wire in regard of the portion thereof between the wire guiding means and the force changing means into a position substanlever on said frame; and means for pivotally mountingsaid cylinder on said frame.
  • said tensioning device is a wire; wire guiding means are provided over which said wire extends; and said wire guiding means is adjustable to change the orientation of the medium direction of the portion of said wire between said wire guiding means and said force changing means to a position substantially parallel to the medium direction of said piston rod.
