Definitions

  • the present invention also includes a casting technique that can be used in various fields, such as a casting method when creating a prosthetic limb such as a prosthesis or an artificial hand, a casting method when creating a prosthetic device used in orthopedic surgery, and a casting technique. Therefore, it relates to a molding technology that can easily form a desired three-dimensional shape.In particular, in the molding technology, it is shorter than the conventional molding technology performed using gypsum or a plaster bandage. This is a technology that can be used simply and finely in a dry process. Background art
  • Gypsum bandages in which gypsum is adhered to gauze bandages are mainly used for casting.
  • Gypsum bandage which has been cut to an appropriate width in advance according to the type to be cast, is temporarily immersed in water or lukewarm water, and immediately wound around the affected area such as a stump to be cast while the gypsum does not dry. Have done the type.
  • a tricot soaked in water is placed over the stump of the patient and secured with a string. Mark prominent irregularities such as the epiphysis on the tricot with a copy pencil.
  • the gypsum bandage which has been softened by immersing it in water or lukewarm water as described above, is quickly wound onto the tricot with a certain winding force so that the unevenness of the affected part is reproduced. It must be wound before the plaster does not solidify.
  • the plaster bandage thus set solidifies, the plaster bandage is removed from the affected area to form a so-called female type (also called a negative model).
  • female type also called a negative model
  • plaster is poured in a state where a mandrel such as an iron bar is set up at the center of the female mold, and then solidified to form a male mold (also referred to as a positive model).
  • the male part is used to form the prosthetic limb and the prosthetic device for the affected area.
  • the quality of the initial female mold casting will determine the quality of the final fit of the prosthetic device to the affected area.
  • gypsum is used where gypsum bandages cannot be used.
  • the surface of the sole and the like can not be skillfully cast with gypsum bandage, and the method of shaping is performed by pressing the sole against gypsum mud in a softened state to some extent.
  • a method called sketch measuring is also used.
  • Casting is actively used in fields other than medicine. For example, in the field of plastic arts, elaborate reproductions of natural objects, including human bodies, are sometimes performed. For such reproduction, casting using gypsum is indispensable. When duplicating an elaborate human face, it is necessary to press the face against the softened gypsum surface, hold the breath for a while in that state, etc., to keep the face still, and then relax and remove the face from the gypsum surface Have been done.
  • gypsum As described above, a casting technique using gypsum has been used in various fields. However, most of the methods use gypsum in a wet state, that is, in a state of gypsum mud.
  • the plaster bandage must be wrapped neatly while the plaster is not dry, with a moderate amount of wrapping force while the plaster is softening without excessively pressing the soft tissue of the affected area. It usually takes about 5 minutes to complete the task. Therefore, considerable skill is required to perform good casting.
  • gypsum dressings need to be soaked in water or lukewarm water before use, so that the gypsum powder contains water. It is necessary to drain water appropriately so that the formed muddy gypsum mud does not run off from bandages such as gauze.
  • bandages such as gauze.
  • a long plaster bandage is wound into a roll and dipped in water for an appropriate period of time, and the end of the roll is drained by gripping the roll end.
  • the degree of drainage differs from the outside of the roll, which may affect the casting operation. However, it is practically impossible to perform powerful drainage evenly.
  • the affected area to be molded is stained with gypsum mud.
  • the affected area is required to be as dirty as possible, which is a major problem. If dry casting can be performed, the problem of power will be solved.
  • the gypsum itself after solidification is extremely fragile and requires careful handling. If the plaster mold is damaged, it is difficult to repair it and must be remolded. Casting must be performed by a prosthetic orthotist for a considerable amount of time, which makes it difficult to provide patients with orthotics.
  • the wet gypsum solidifies while generating heat while in contact with the skin, so if the wound state is maintained for a certain period of time, in the case of people with weak skin, Irritation due to gypsum may occur. In particular, at the stump, the affected area is often different from the outer skin on the body surface side, and is more sensitive to stimuli.
  • a prosthetic device does not have to be done for many years without having to do it for a long time.
  • children, etc. should appropriately cast their prosthetic devices so as to match the growth rate according to their age. It is necessary to ensure the proper mounting state of the prosthesis, and there is a need for a technology that can easily and quickly perform the molding, instead of the complicated molding method of the conventional molding described above.
  • many people have been injured by land mines in conflict areas around the world, and many prostheses have been required on site.
  • more elaborate casting is required, and since the preparation of the plaster mold at present requires an experienced person, it is hardly expected that smooth casting will be performed on site.
  • the inventor of the present invention has thought that it is possible to help save the present situation by developing a technology that allows even an amateur to easily perform casting in such a painful situation.
  • the casting technique easy and without any special knowledge, the casting of many disabled persons can be done quickly at the local site, and the prosthetic limb can be brought back to a country free from war damage. It is thought that the creation of this system will facilitate the supply of prostheses and support the rehabilitation of many people.
