Problems solved by technology

Because the splint fixation is easy to dislocate the fracture surface after reduction, resulting in deformity and functional defect of the fixed part; and plaster cast or polymer bandage cast is difficult to adjust the circumference of limbs before and after bone injury due to high difficulty in operation. Its poor air permeability and other problems are not conducive to doctors' timely examination and treatment of surface surgical trauma at the bone wound, etc.
If tube-type fixation is used, it is easy to cause joint adhesion and joint ankylosis, etc.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with examples.

[0021] The invention discloses a rigid molding process for the calf of a human body. The rigid molding process is completed through a cavity of the calf, and the cavity of the calf includes two cavities that are left-right symmetrical and connected as a whole. Rigid molding technique of the present invention comprises the following steps:

[0022] S1: Make the temperature of the raw material polyether polyol mixture and the modified isocyanate reach 20-25°C, then mix and stir them, the stirring speed is 1500 rpm, and the stirring time is 24-25 seconds, fully mix well and evenly react to prepare Obtain polyurethane slurry;

[0023] S2: Pour polyurethane slurry into one cavity first, and when the cavity is half-filled, continue to pour and start pouring polyurethane slurry into the other cavity after 3.3 seconds, so that the two The polyurethane slurry content and reaction degree of th...

Abstract

The invention discloses a rigid molding process used fora shanks of a human body. The rigid molding process comprises the following steps: stirring polyurethane slurry; injecting the polyurethane slurry into a mould cavity; uniformly spreading the polyurethane slurry in the mould cavity; covering the mould cavity on a shanks and a footeet of a user; and finally, molding. The rigid molding process used for the shanks of the human body realizes standard molding of the shanks of the human body quickly and accurately, is simple and convenient to operate, and is easy to popularize.

Description

technical field [0001] The invention relates to a shaping process, in particular to a rigid shaping process for human lower legs. Background technique [0002] The traditional non-surgical external fixation that has continued to this day mostly uses plaster bandage casts, polymer bandage casts or splints for fixation. Because the splint fixation is easy to dislocate the fracture surface after reduction, resulting in deformity and functional defect of the fixed part; and plaster cast or polymer bandage cast is difficult to adjust the circumference of limbs before and after bone injury due to high difficulty in operation. Poor air permeability and other problems are not conducive to doctors' timely examination and treatment of surface surgical trauma at bone injuries. If tube-type fixation is used, it is easy to cause joint adhesion and joint ankylosis. [0003] Chinese patent CN203042573U discloses a cavity for orthopedic external fixation of the lower leg. The cavity is wr...
