Manufacturing method for 3D orthopedic insole

Abstract

The invention relates to a manufacturing method for a 3D orthopedic insole. The manufacturing method comprises the following steps: carrying out imageological examination on an ankle on a load bearing position or carrying out imageological examination on a non-load-bearing position of the orthopedic ankle; introducing three-dimensional modeling software into a scanned image to generate three-dimensional models of foot bones and feet; inducing an insole curved surface matched with a sole according to the three-dimensional model of the feet; carrying out orthopedic operation on the insole curved surface according to the three-dimensional model of the feet and the specific types of the foot bones to obtain the orthopedic insole curved surface; and printing the insole corresponding to the orthopedic insole curved surface by a 3D printer. By the aid of the manufacturing method, the insole can be individually customized, and the targeted orthopedic insole is manufactured according to the changes of the feet of patients.

Description

technical field [0001] The invention relates to a manufacturing method of a 3D orthopedic insole, which is applied in the field of insole manufacturing. Background technique [0002] Orthopedic insoles are widely used in orthopedics, orthopedics and rehabilitation. Flat feet, high arched feet, plantar fasciitis, heel hyperostosis, diabetic plantar ulcers, hallux valgus, gout, subtalar joint subluxation, lower extremity rotational deformity, knee arthritis, meniscus injury, cruciate ligament Injuries and so on can be improved by orthopedic insoles, delaying the development of diseases, correcting force lines or as postoperative rehabilitation. [0003] Patients with flat feet become flat due to the collapse of the arch, and the rear foot becomes shorter after the arch is lost, which relaxes the anterior and posterior tibial muscles, reduces the ability to maintain the arch, and aggravates the formation of flat feet. The brevis muscle loses the antagonism of the tibialis ant...

AI Technical Summary

Problems solved by technology

2. The patient's individual foot bone arrangement cannot be considered, such as whether there is dislocation of the talonovicular joint and the degree of dislocation, whether there is calcaneus valgus deformity and the degree of valgus, so it is impossible to make an accurate correction design for the deformity

It has the following problems: 1, the basis of shaping is the contour of the patient's foot, rather than the imaging changes of the bone structure of the patient's foot

The measurement of deformity and the design of the orthopedic part of the insole cannot achieve uniform accuracy

2. The insole design is done by the technicians of the brace company, not the doctors. That is, the diagnosis and insole production are done by different departments, resulting in a disconnect. Technicians who lack medical theoretical knowledge cannot combine the clinical design of orthopedic insoles perfectly.

3. The mold taking and product production are completed in multiple steps, so it is difficult to guarantee the accuracy of the product

4. Orthopedics is a long-term process, and it may take a long time to replace orthopedic insoles of different heights and positions. Using the original custom method requires a corresponding number of impressions, which is a great waste of manpower and material resources

It has the following problems: 1. The plantar pressure test can only analyze the position and degree of the arch collapse, and the computer cannot judge the specific changes in the alignment of the foot bones, such as whether there is dislocation of the talonovicular joint, the degree of calcaneus valgus, whether it is soft or not. Stiff flat feet etc.

Because each situation requires targeted orthopedics, which cannot be analyzed by the plantar pressure tester, which can only make insoles that correct the height of the medial arch

2. The production of insoles is the participation of computer software and insole designers. Without the detailed understanding and guidance of doctors on patients' conditions, it is impossible to achieve targeted results

3. CNC machine tools are time-consuming and costly to process complex curved surfaces of insoles, and have high requirements for machine operators

In addition, CNC machine tools are almost unable to process soft materials, and the selection of materials is already very limited, requiring complex processing in the later stage

The process is cumbersome and the cost is high

4. The production of CAD / CAM insoles requires plantar pressure analyzers, foreign special insole production software, machine tools and other equipment. The investment is huge, and the insoles are not fundamentally designed from the analysis of the patient's bone deformity
