Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] first embodiment

[0026] An orthopaedic plaster cast expander for fracture healing, such as Figure 1-2 As shown, it includes an arc-shaped rod 1 , a fixing mechanism 2 and an expansion mechanism 3 .

[0027] The fixing mechanism 2 includes a rotating shaft 21, a first arc-shaped plate 22, a second arc-shaped plate 23 and a clamping plate 24. A rotating shaft 21 is rotatably connected to the upper part of the arc-shaped rod 1, and a first arc-shaped plate 22 is connected to the right side of the rotating shaft 21. , the left side of the rotating shaft 21 is rotatably connected with a second arc-shaped plate 23, and the tops of the first arc-shaped plate 22 and the second arc-shaped plate 23 are connected with a clamping plate 24.

[0028] The expansion mechanism 3 includes a first groove plate 31, a first sliding nut 32, a first screw 33, a shaf...

Abstract

The invention relates to a dilator, in particular to an orthopaedic plaster cast dilator after fracture healing. The technical problem to be solved by the present invention is to provide an orthopaedic fracture-healing plaster cast expander that can save manpower during operation and ensure patient safety during operation. In order to solve the above technical problems, the present invention provides such an orthopaedic fracture healing plaster cast expander, which includes: an arc-shaped rod, which is arranged on the arc-shaped rod; an expansion mechanism, which is arranged on the fixing mechanism and the arc-shaped rod. There is an expansion mechanism in between. The present invention expands the plaster mold through the cooperative operation of the fixing mechanism and the expansion mechanism, thereby achieving the effect of expanding the plaster mold. The present invention bends the plaster mold through the bending mechanism to avoid the occurrence of the plaster mold when the plaster mold is expanded. The deformation squeezes the patient's leg.

Description

technical field [0001] The invention relates to a dilator, in particular to an orthopaedic plaster cast dilator after fracture healing. Background technique [0002] Gypsum is a monoclinic mineral and 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 additives, sulfuric acid production, paper filler, paint filler, etc. Plaster can be used to assist orthopaedic patients in the recovery of fractures. After the fracture has healed, 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 manually expand the plaster mold by manually breaking the cutting part of the plaster mold. The above method requires manual breaking of the plaster mold during the operation, and it takes a lot of time to break the plaster mold. Large force is ...
