Definitions

  • the present invention relates to a jointing device for bone breaks and fractures, and more particularly, to the device of a shape-memory alloy used to joint the bone breaks and fractures to simplify the process of the necessary treatment such as an operation and to make the area to be treated minimum, for enabling the time for recuperation should be shortened.
  • the jointing device for bone has been used in the orthopedic surgery for jointing the broken or fractured bone.
  • Conventional device usually includes an elongated plate and the screw for fixing the bone, the elongated plate for holding the fractured or broken bone, so that the frame of the bones is maintained as it should.
  • Each sides of the broken bone should be pierced for the screw and a certain kind of the operation should be accompanied on the injured area.
  • the operation may also include a process for introducing the plate into the injured area. Accordingly, the disadvantages of the conventional device lies in the fact that the necessary area to be incised is not localized small and it prolongs the operation time.
  • a jointing device for bone breaks and fractures with a clamp 10 made of a shape-memory alloy, in the shape of C", for fastening and fixing the injured bones upon change of the shape thereof by the human temperature.
  • the clamp 10 of a shape-memory alloy which is introduced into the skin and surrounds the injured bones of the body, is re-shaped dependent on the memorized human temperature, thereby fastening and fixing the injured bones.

  • a jointing device for bone breaks and fractures wherein the shape is variable at a predetermined human temperature before stable installation on the broken bone.
  • the clamp 10 is in a shape of a ring of a shape- memory alloy in which a part of loop is opened as *C", and the gap of the opened loop is varied by the human temperature, thereby fastening and fixing the injured bones .
  • At least one clamp is used for fastening the bones as shown in Fig. 2.
  • one end of the clamps acting as a fastener 11 is connected by the connection 12, making the device in a unit.
  • one end of the clamps, fastener 11 is inserted to and fixed with the broken bones, making the jointing device by the connection 12 in a unit.
  • the jointing device of the present invention includes a clamp 10, fastener 11 and connection 12, all of which is made of a shape-memory alloy.
  • the jointing device of the shape-memory alloy is designed to vary at Ms 10°C and As 30°C and cooled by the saline solution at a low temperature, so that the shape of the shape-memory alloy is readily recovered by the human temperature, thereby fastening and fixing the broken bone.
  • the jointing device of a shape-memory alloy is manufactured by the shape-memory heat treatment for one hour at the temperature of 650 - 700°C.
  • the size of the jointing device is variable dependent on the injured part.
  • a gap of the jointing device is widened at the martensite point which is below 10°C.
  • the operator may widen the gap of the jointing device more than the diameter of the broken bone, and place the device on the desired location.
  • a predetermined time e.g. one or two minutes
  • the temperature of the device rises according to the temperature of human body. Once the temperature has reached above 30°C, austenite point, the device is transformed and the shape of the device is restored to the original ⁇ C" shape.
  • the clamp 10 is placed on the human body, with each ends being wider than the desired size, and transformed by the human temperature, to fix and joint the injured bones .
  • the jointing device of the present invention enables the fractured bone to be jointed in a fixed condition of the bone in a very short time without incurring the harmful damages on the bone such as perforation in the bone. Further, the present jointing device enables the simple operation by minimizing the operation time and area, for enabling recovery in a short period of time.

Abstract

L'invention concerne un dispositif de fixation pour fractures osseuses constitué d'un alliage à mémoire de forme. Ce dispositif comprend une attache (10) se présentant sous la forme d'un C et servant à fixer des fragments osseux ou des os fracturés, d'où une simplification du traitement nécessaire étant donné que l'opération s'effectue sans perforation osseuse. Ce dispositif permet également de réduire au maximum la zone d'incision, et donc de diminuer le temps de cicatrisation.
