Orthopedic pressure die based on digital image data

Abstract

The invention discloses an orthopedic pressure die based on digital image data, and belongs to the technical field of orthopedic equipment. The orthopedic pressure die comprises a shell, a pressure pump, a data collector and an image conversion device, a plurality of pressure bars arranged at equal intervals are mounted at the inner top and the inner bottom of the shell, and the shell is provided with an oil injection hole and an air leakage hole. According to the orthopedic pressure die, a three-dimensional CT model image of an affected part is imported into the image conversion device, machining data are calculated in combination with initial information, uploaded by the data collector, of a to-be-machined steel plate, the corresponding pressure bars are controlled to move to designated positions, and the steel plate located in the shell is pressed. Manual operation of doctors is not required in the whole machining process, and the die has the advantages that the die is high in manufacturing efficiency, free of repeated adjustment and high in fitting degree. The fixing steel plate can be customized on the basis of the affected part, and meanwhile, the work intensity of the doctors can be reduced.

Description

technical field [0001] The invention relates to the technical field of orthopedic equipment, and more specifically relates to an orthopedic pressure mold based on digital image data. Background technique [0002] When the body is impacted or fell from a height, etc., due to the impact on the bones, fractures are prone to occur. Some fractures are significantly displaced, affecting activities and requiring surgical treatment. Surgical treatment requires the use of internal fixation equipment for reduction and fixation, so as to facilitate the recovery of the fracture site. Plates are currently the most common internal fixation device. [0003] At present, the steel plate used for fixing the fracture site is usually made by hand. During the operation, the doctor needs to make it on the spot according to the condition of the patient's fracture site, and then according to his own experience. Because the strength of the steel plate is relatively high, the doctor is in the proce...

Problems solved by technology

[0003] At present, the steel plate used for fixing the fracture site is usually made by hand. During the operation, the doctor needs to make it on the spot according to the situation of the patient’s fracture site, and then according to his own experience. Because the strength of the steel plate is relatively high, the doctor is making the steel plate. In the process, it takes a lot of time and energy to compare and trim repeatedly, and the production efficiency is low, which increases the work intensity of doctors. In addition, the manufactured steel plates also have problems of poor precision, repeated adjustments, and poor fit. This has adverse effects on the recovery of patients in the later period.
