3D printing fracture rehabilitation support replacing gypsum

Abstract

The invention relates to a 3D printing fracture rehabilitation support replacing gypsum. The 3D printing fracture rehabilitation support replacing gypsum comprises a first clamping plate, fastening pieces, a second clamping plate and a connecting pipe, wherein the first clamping plate is in sliding connection with the second clamping plate and fixedly connected with the second clamping plate through a plurality of groups of fastening pieces; a first air bag is arranged on the inner end surface of the first clamping plate, and a first hollow bin is arranged in the first clamping plate; a plurality of groups of exhaust pipes, a first air conveying pipe and a third air conveying pipe are arranged in the first hollow bin; a plurality of groups of first vent holes are formed in the inner end surface of the first clamping plate by the exhaust pipes; the exhaust pipes and the first air conveying pipe are connected with the third air conveying pipe; the air inlet end of the third air conveyingpipe is connected with a second air conveying pipe for circularly conveying cold and hot air; a plurality of groups of second air bags are arranged on the inner end surface of the second clamping plate, and a second hollow bin is arranged in the second clamping plate; the second hollow bin is provided with a plurality of second vent holes in the inner end surface of the second clamping plate; andthe second hollow bin is connected with the first air conveying pipe through the connecting pipe. The 3D printing fracture rehabilitation support replacing gypsum is convenient to use and can well fix fractured limbs of a patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a 3D printed fracture rehabilitation bracket that replaces gypsum. Background technique [0002] Fracture refers to the complete or partial rupture of the continuity of the bone structure, which is more common in children and the elderly, and sometimes occurs in young and middle-aged people; after a fracture occurs, the muscles attached to the bone will contract spasmodically, so it is very painful; the healing of the fracture takes a long time. During the period of time, gypsum is often used to fix the patient's fracture. The gypsum fixation steps are too cumbersome, and the gypsum has poor air permeability. During the fracture healing process, there will be a phenomenon of detumescence. As a result, the limbs cannot be closely attached to the gypsum in the later stage, which affects the healing of the bone in the later stage; when the gypsum is removed, it needs to be r...

[0002] Fracture refers to the complete or partial rupture of the continuity of the bone structure, which is more common in children and the elderly, and sometimes occurs in young and middle-aged people; after a fracture occurs, the muscles attached to the bone will contract spasmodically, so it is very painful; the healing of the fracture takes a long time. During the period of time, gypsum is often used to fix the patient's fracture. The gypsum fixation steps are too cumbersome, and the gypsum has poor air permeability. During the fracture healing process, there will be a phenomenon of detumescence. As a result, the limbs cannot be closely attached to the gypsum in the later stage, which affects the healing of the bone in the later stage; when the gypsum is removed, it needs to be removed by professionals, which is very inconvenient. In addition, the gypsum is a disposable product and cannot be recycled for multiple uses; therefore, in this application Propose a 3D printed fracture rehabilitation bracket instead of plaster
