Individualized customized implantation material shaping device for 3D printing and manufacturing method thereof

Abstract

The invention discloses an individualized customized implantation material shaping device for 3D printing and a manufacturing method thereof. The individualized customized implantation material shaping device is characterized in that the shaping devices are divided into three types: a guide plate or mold with the skeleton surface as a basis after a most ideal digital reset, para-position and alignment skeleton model is established, a guide plate or mold with establishment of a digital most-ideally installed most-ideal implantation material model of an implantation material as basic design and a shaping device mainly used for a tissue defect repairing implantation material and a prosthesis implantation material. The manufacturing method comprises the steps that firstly, the digital skeleton model is obtained through modeling based on a reverse engineering technology; secondly, reset or osteotomy shape-correcting operation is conducted on the skeleton model according to the operation purpose to make skeleton model reach a final ideal state required by an operation, and material obtaining is performed on the basis to establish various characteristics gradually. The individualized customized implantation material shaping device has the advantages of saving operation time, relieving the suffering of patients, more facilitating the operation, being low in access threshold and the like.

Description

Technical field [0001] The invention relates to the field of computer-aided modeling, and in particular to an individualized customized implant shaping positioning guide, a mold and a rapid prototyping method. Background technique [0002] Orthopedic surgical implants are often products with uniform specifications and parameters. They often require doctors to shape them before implanting in the human body to better fit a specific patient for implantation. The cost of individualized printed implants is often higher. There are clinical cases of internal fixation shaping of 3D printed bone models before surgery, but this technology is also limited by factors such as the cost of bone model printing, so it has not been widely promoted in clinical practice, and printed bone models cannot be used intraoperatively. Because of the positioning and guidance, the function is single, so it is necessary to design clinical shaping guides and molds with lower cost, more functions, and convenient...

Problems solved by technology

[0002] Orthopedic surgery standard implants are often products with uniform specifications and parameters. Before implantation in the human body, doctors often need to shape them to better fit specific patients for implantation. The cost of individualized printed implants is often high , there are clinical cases of 3D printing bone models for internal fixation before surgery, but this technology is also limited by factors such as the cost of bone model printing, so it has not been widely used in clinical practice, and the printed bone models cannot be used during surgery. It is based on positioning and guidance, and has a single function. Therefore, it is necessary to design clinical shaping guides and molds with lower cost, more functions, and easy popularization and application.
