Problems solved by technology

[0003] In the traditional DDH osteotomy, the doctor first determines the osteotomy angle of the patient's femoral rotation osteotomy based on two-dimensional medical images and the doctor's clinical practice experience, and then performs femoral rotation during the operation using only the doctor's clinical experience and existing measurement tools Osteotomy leads to low surgical accuracy, long operation time, high risk of surgical trauma and other complications, and certain radiation hazards

Abstract

The invention discloses a DDH (Developmental Dysplasia of Hip) osteotomy guide plate. The DDH osteotomy guide plate comprises a fixed end and a rotary end, which are fitted onto the surface of a bone of an osteotomy region; the fixed end is connected with the rotary end through a connecting module. According to the DDH osteotomy guide plate, the surgical precision can be improved by adopting the osteotomy guide plate; surgical steps in a surgery are simplified and the surgical time is shortened; a doctor does not need to judge a correction angle by experience in an orthopedic osteotomy surgery, so that the accuracy is improved and surgical risks are reduced. Meanwhile, the demand threshold on experience of doctors by the surgeries is reduced. The invention provides a manufacturing method of the DDH osteotomy guide plate; the osteotomy guide plate can be accurately and conveniently manufactured by adopting the manufacturing method. The invention provides an application method of the DDH osteotomy guide plate and the surgical time can be shortened by the method.

Description

technical field [0001] The invention belongs to the technical field of osteotomy orthopedic surgery equipment, and in particular relates to a DDH osteotomy guide plate, a method for making the osteotomy guide plate, and a method for using the osteotomy guide plate. Background technique [0002] In the field of biomedicine, modern medicine tends to individualized treatment strategies. With the strong improvement of computer computing power, the extensive and in-depth combination of computer technology and medicine has formed an emerging interdisciplinary field - digital medicine, which has greatly promoted the development of modern clinical medicine. Development of personalized diagnosis and treatment technology. At the same time, because 3D printing has individual characteristics, it is just in line with the concept of diagnosis and treatment of modern medicine. Therefore, it will be a match made in heaven to apply 3D printing technology to the field of biomedicine. At pres...
