Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments do not limit the present invention.

[0039] see figure 1 and 2 , a three-dimensional printing protective gear, including several fixing rings 5, a first main body 1 and a second main body 2, the cavity formed by splicing the first main body 1 and the second main body 2 matches the affected part, and its specific shape depends on the shape of the protective gear Design for the purpose of use needs to fit the shape of the affected area. According to the shape of the skin of the affected area, the size and shape of the main body and the fixing ring can be designed in the three-dimensional software. This example gives a preferred main body thickness of 3mm. A pair of multiple semi-cylindrical locking pieces are provided on the edge...

Abstract

The invention belongs to a medical rehabilitation protection device and a manufacturing method thereof, and particularly relates to a three-dimensional printing protection device and a printing methodthereof. The problem that existing protection devices are inconvenient to adjust according to the change of the affected part can be solved. The protection device is formed by splicing two parts of main bodies based on additive manufacturing, the two main bodies cooperate with each other through fixing rings and locking columns and are used for connecting fixation and limitation, the shape can bedesigned according to the affected part of a patient, the fitting degree is high, the weight is low, the strength is high, and the protection performance is good. Particularly, a fixing device is formed by the fixing rings and the locking columns, thelocking columns of the two parts can be jacked tightly to complete fixation simply by sleeving and rotating the fixing rings, mounting and dismounting are convenient, and the use is convenient; in addition, the elastic adjustment can be carried out in cooperation with different fixing rings according to the swelling degree of the affected part indifferent stages, and bone displacement and other problems are effectively prevented. The whole protection device is accurate to splice and position, a malposition phenomenon does not easily occur, the affected part is fastened more reliably, and the protection device has the advantage of being suitable for various affected parts.

Description

technical field [0001] The invention belongs to medical rehabilitation protective gear and a manufacturing method thereof, in particular to a three-dimensional printing protective gear and a printing method thereof. Background technique [0002] The traditional protective gear external fixation methods include small splints, high bandages, abduction frames, continuous traction, and needle external fixators. Because the traditional plaster bandage fixation method is complex, bulky and has poor air permeability, patients are prone to symptoms such as itchy skin and dampness. After the swelling of the limbs is reduced, the fracture will be redisplaced due to the looseness of the plaster. Long-term immobilization may also cause joint stiffness and muscle atrophy, and even lead to serious dysfunction. Traditional plaster fixation also increases the workload of medical staff. In addition, there are differences in the body structure of different patients, which is also difficult t...
