Plaster mold expander applied after fracture healing for orthopedics department

Abstract

The invention relates to an expander, in particular to a plaster mold expander applied after fracture healing for the orthopedics department. The invention aims at solving the technical problem so asto provide the plaster mold expander applied after fracture healing for the orthopedics department, so that manpower can be saved during operation, and the patient safety is guaranteed during operation. In order to solve the technical problem, the invention provides the plaster mold expander applied after fracture healing for the orthopedics department. The plaster mold expander applied after fracture healing for the orthopedics department comprises an arc rod, a fixing mechanism arranged on the arc rod, and an expanding mechanism arranged between the fixing mechanism and the arc rod. According to the plaster mold expander applied after fracture healing for the orthopedics department provided by the invention, a plaster mold can be expanded through the coordinated operation of the fixing mechanism and the expanding mechanism, so that an effect on expanding the plaster mold is achieved; and the plaster mold is bent through a bending mechanism, so that the plaster mold is prevented frombeing deformed to squeeze a leg of a patient during expanding.

Description

technical field [0001] The invention relates to a dilator, in particular to a dilator for a plaster cast after fracture healing in orthopedics. Background technique [0002] Gypsum is a monoclinic mineral, a hydrate whose main chemical composition is calcium sulfate (CaSO4). Gypsum is a versatile industrial and construction material. It can be used in cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. Plaster can be used to assist the recovery of orthopedic patients after a fracture. After the fracture heals, the plaster cast needs to be cut off and then expanded and taken out. [0003] At present, the way to expand the plaster mold is usually to expand the plaster mold by manually directly using the cutting part of the plaster mold by hand. Large strength is relatively labor-intensive, and the plaster mold will be deformed when the plaster mold is moved, and it is easy to squeeze the ...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the disadvantages of the above-mentioned method, which is relatively labor-intensive in operation, and the plaster mold will be deformed when the plaster mold is moved, it is easy to squeeze the fracture of the patient again, which will cause medical accidents. The technical problem to be solved by the present invention It is to provide an orthopedic post-fracture plaster cast dilator that can save manpower during operation and ensure the safety of patients during operation.
