Problems solved by technology

However, the normal activities of patients after joint fusion surgery are limited, and it is difficult to heal after implantation of autologous bone and allogeneic bone, and they face a greater risk of infection
However, due to the special structure of the human pelvis, the artificial prosthesis design is difficult to meet the requirements, often resulting in difficulty in installation and compression of the sciatic nerve after surgery
In addition, different types of prosthesis may greatly increase the probability of prosthesis loosening, fracture, and dislocation, and the production price of the prosthesis will also increase significantly, which increases the economic burden of the patient, or the materials required for the production of the prosthesis are relatively low. more, so the cost is higher
In addition, large-sized prostheses require larger incisions during surgery, prolonging the recovery period of patients and increasing the risk of infection

Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Please combine Figure 1 to Figure 2 As shown, the personalized customized pelvic prosthesis 100 of the present invention is used to fill the defect of the pelvis. In the present invention, the pelvic prosthesis 100 is applied to implant filling after osteotomy of the lesion area of ​​the tumor segment of the iliac part of the pelvis.

[0029] The pelvic prosthesis 100 includes a reconstruction body 1 for filling the ilium defect, the shape of the reconstruction body 1 bionics the mirror image of the ilium defect and corresponds to the normal side ilium, the middle part of the reconstruction body 1 and the ilium The outer edge of the contact is provided as a porous structure.

[0030] The pelvic prosthesis 100 is designed by indus...

Abstract

The invention provides a personalized customized pelvic prosthesis and a manufacturing method thereof. The manufacturing method comprises the following steps that a two-dimensional or three-dimensional image of the pelvis of a patient is obtained, the tumor invasion situation of the pelvis is determined, and the pelvis range needing to be cut off is determined according to the tumor invasion situation; the whole pelvis image data is separated, half pelvis image data on the left side and the right side after separation are respectively reconstructed, the appearance of the pelvis on the affected side is repaired in industrial software, and smoothing and repairing are carried out on the appearance of the pelvis; the boundary of the pelvic prosthesis is determined according to the tumor invasion condition and the normal pelvic boundary by using industrial software, and the image data of the normal pelvic is mirrored to obtain the image data of the pelvic prosthesis in the resection area of the patient; a porous structure is set in the middle of a pelvic prosthesis by utilizing industrial software, and the proportion of the porous structure in the middle to the whole is calculated according to sclerotin around the prosthesis; and a porous structure is arranged on the outer edge portion, making contact with the pelvis of the patient, of the pelvic prosthesis through industrial software.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a personalized customized pelvic prosthesis and a manufacturing method thereof. Background technique [0002] The weight of a normal person is transmitted from the lumbar spine down to the pelvis, from the pelvis to the ilium on both sides through the sacroiliac joint, and then through the left and right ilium to the left and right femur through the left and right hip joints. Cases of pelvic tumors are relatively rare, and both primary and metastatic tumors require resection. After the resection of the primary malignant tumor around the pelvis is completed, it is often accompanied by a large number of structural defects, including the destruction of the pelvis, iliac crest, acetabulum, and femur. If surgical repair and reconstruction are not performed, defects in bone support function and loss of motor function will inevitably follow after surgery. Good repair and reconstruction ...
