Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below.

[0021] A method for adjusting the negative shape of the prosthetic plaster of the thigh, comprising the steps of:

[0022] (1) Prepare cling film, taking pen, water, knife, scissors, plaster bandage, cutting strips, calipers, tape measure, let the patient sit in a chair, wrap the cling film on the residual limb; draw bony marks and residual limb For the pressure-free part, review the postoperative wound healing of the stump, draw the negative pressure sensitive part of the residual limb, the bony protruding part, the skin graft part, and the scar part;

[0023] (2) Measure the length of the residual limb, the height of the residual limb to the ground, and the circumference of the thinnest and thickest part of the residual limb;

[0024] (3) Prepare the gypsum reinforcement strip, wrap the reinforcement strip from the lower end of the residual limb to the thigh along the bottom of the res...

Abstract

The invention discloses a gypsum female shape adjusting method for an artificial limb. The method comprises the steps of (1) taking a gypsum female model from the artificial limb, and keeping a preservative film or silk stockings of a patient on; (2) shearing the mouth shape of the gypsum female model according to the size of the artificial limb; cutting two openings in the front portion and the rear portion of the inner side of the artificial limb and opening downwards by 3 to 5 cm; forming an opening in the middle of the outer side of the artificial limb to reach the stump end of the artificial limb by 5 to 8 cm; (3) sleeving the cut gypsum female model on the residual limb again, so that the gypsum female model correspondingly fits the residual limb; and (4) supporting the gypsum femalemodel, and retracting the residual limb inwards by 5 to 15 degrees; reducing the gap in the outer side of the gypsum female model; attaching the opening in the middle of the outer side of the gypsumfemale model to the residual limb, and making a mark on the lap joint; repairing the model; reducing the model girth to complete shape adjustment. According to the invention, the gypsum female model is adjusted according to the adduction gravity line required by the walking of the patient; the stress is uniform and the comfort level is improved after fitting wearing; and the gait is closer to thegait of a normal person.

Description

technical field [0001] The invention relates to a manufacturing process of artificial limbs, in particular to a method for adjusting the negative shape of artificial limbs with gypsum. Background technique [0002] In recent years, the number of amputations caused by traffic accidents, natural disasters, cardiovascular diseases, diabetes and other diseases has been increasing. According to the "Major Data Bulletin of the Second National Sampling Survey on Disabled Persons", the total number of people with various types of disabilities in my country is about 82.96 million, of which about 24.12 million are physically disabled, and about 2.26 million are amputated, including lower limb amputations. Most of them. Prosthetics are an important means to help physically disabled users recover and return to society by compensating for the shape and function of their limbs. The prosthesis is mainly composed of three parts, including a supporting part that imitates the function of the...
