Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a personalized three-dimensional bone chip manufacturing device based on mechanical cutting. Background Art

[0002] As common otological diseases, cholesteatoma of the middle ear and external auditory canal require, during treatment, reconstruction of the posterior wall of the external auditory canal as a common treatment method. This surgery requires an implant that precisely matches the shape of the patient's ear canal to repair and reconstruct the posterior wall of the external auditory canal, thereby achieving a good treatment effect.

[0003] Currently, most existing implants are made of materials such as 3D-printed calcium phosphate and bioceramics to fabricate the structure to be transplanted. However, regarding the air cavity structure of the mastoid, there have been no relevant reports on the successful application of artificial materials so far. This makes the existing materials have poor adaptability when fabricating relevant structures. Among various materials available for transplantation, autologous transplantation has the best adaptability, and using one's own autologous mastoid cortical bone as the graft is typical. This autologous transplantation method has significant advantages. Due to its good compatibility, it does not cause rejection reactions. However, in actual operation, the removed bone body is usually of a standard specification, and the bone body required for transplantation for each patient needs to be customized according to individual differences. Currently, this customization work is mainly completed by medical staff through manual carving. Manual carving not only has low efficiency but also has large carving errors, making it difficult to precisely meet the needs of patients. In addition, it is difficult to create an ideal aseptic environment during the manual carving process, increasing the risk of bone body contamination, which will have an adverse impact on the subsequent transplantation effect.
