3D orthopedic finger separating plate and fabrication method

Abstract

The invention relates to the field of medical equipment, in particular to a 3D orthopedic finger separating plate and a fabrication method. The 3D orthopedic finger separating plate comprises a body,wherein the body is composed of a palm plate and finger plates; carpometacarpal joint fixing strip-shaped holes are formed in the sides, close to a human wrist, at two sides of the palm plate; metacarpophalangeal joint fixing strip-shaped holes are formed in the sides, close to a human finger, at two sides of the palm plate; proximal interphalangeal joint fixing strip-shaped holes are formed in two sides of each finger plate; a plurality of air holes are formed in each finger plate; and hollowed-out patterns are arranged on the body between each finger plate and the adjacent finger plate. The3D orthopedic finger separating plate is air-permeable, comfortable and personalized in appearance, collects a hand model of a patient by using 3D optical scanning, accurately processes data by usingthree-dimensional software, meets the requirements for hand shape treatment of the patient and fits the hand curve of the patient. The 3D orthopedic finger separating plate is low in fabrication difficulty, simple in structure and convenient to operate; fixation is implemented through cooperation of the fixing strip-shaped holes formed in carpometacarpal joints, metacarpophalangeal joints and interphalangeal joints, a hook-and-loop fastener and a curved surface structure, so that the fixing effect is better than that with a planer structure; and the 3D orthopedic finger separating plate is suitable for being worn for a long period of time and is good in patient compliance.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a 3D orthopedic fingerboard and a manufacturing method. Background technique [0002] The fingerboard is a commonly used external fixation brace. It is often used to fix the flexion and spasm of the hand joints of stroke patients during the spastic phase, to continuously fix the stretch, reduce the excessive tension of the flexor muscles, and relieve the pain caused by muscle spasm. Recovery of hand function of the patient; correction of flexion contracture of hand joints in patients with stroke sequelae. Many patients with post-stroke sequelae have formed interphalangeal joint adhesions and finger contractures. If left unchecked, it will lead to skin damage, infection, ulceration, and unpleasant odors in the palms and between the palms and fingers. At the same time, it is extremely difficult for the caregiver to clean the patient's palms and fingers and take care of the nails. ...

AI Technical Summary

Problems solved by technology

Orthotics made of low-temperature thermoplastic plates need to be soaked and softened in a low-temperature water tank at 60-80°C to make shapes. The strength is not high, and there will be certain restrictions on its use scenarios. Due to manual limitations and insufficient precision, the low-temperature production process needs to be shaped , molding, grinding, assembly and other links, the operation is more complicated, and the production cycle is longer. As a kind of subtractive production, there will be more waste in the production process; the production of high-temperature thermoplastic plate orthotics requires plastering of patients. The bandage takes the negative shape and the plaster positive shape, which is difficult to take the model for stroke, and the high-temperature thermoplastic sheet is used for high-temperature molding, which results in longer production and processing time, and it is difficult to adjust the angle and alignment after the production is completed. High-temperature thermoplastic panels have insufficient air permeability, insufficient comfort, and poor patient compliance, resulting in reduced treatment effects and greatly increased costs
