Description

A Custom Absorbable Bone Set

technical field

The utility model relates to the field of medical devices, in particular to a customized absorbable bone set, wherein the customized absorbable bone set includes a bone plate and a fixing element, wherein the fixation can fix the bone set on the patient The broken bone is used to fix the broken bone of the patient. the

technical background

Within the scope of the current medical level, anatomical bone plates are most widely used in the internal fixation treatment of fracture patients. Due to the differences in the bone morphology of individual patients and the differences in the location and degree of fracture of the existing anatomical bone plate, even if the bone plate manufacturer divides the type of bone plate into fine enough, the consistency between the bone plate and the bone surface The position with the screws is still not quite ideal. the

Therefore, in the process of implementing the traditional internal fixation method on the patient's fracture site, the medical staff must prepare sufficient and possible bone plate models and specifications before the operation. Even so, the bone plate does not meet the patient's Therefore, it is often necessary to temporarily reshape the bone plate during the operation, otherwise, it is necessary to sacrifice the correctness of fracture position reduction to accommodate the shape of the bone plate. This method not only increases the arbitrariness in the operation process, but also increases the operation difficulty of the operation, and it is difficult to guarantee the conformity of the bone plate to the surface of the patient's fracture, the stability of internal fixation, and the correctness of the reduction of the fracture. the

In terms of material selection of bone plate, for medical stainless steel, titanium and titanium alloy materials, this kind of cold deformation is theoretically prohibited, because cold bending will change the metallographic properties inside the material, so as to reduce the The strength and corrosion resistance of the board. There are many reasons for the failure of fixing the broken bone at the fracture site of the patient. For example, the reshaping of the bone plate during the operation, the position of the screw hole cannot meet the needs of the broken bone at the fracture site, etc. will have a certain impact on the effect of internal fixation. . In addition, these reasons can also lead to delayed bone healing at the fracture site, malunion or nonunion, and even fracture of the bone plate and difficulty in taking it out. the

In addition to the above technical deficiencies, in the traditional bone plate forming process, what kind of bone plate to use is the final decision. Even orthopedic surgeons who know the characteristics of bone plates can only passively accept products provided by medical device-related companies. In the process of clinical application, even if there is room for improvement in the traditional bone plate, orthopedic surgeons have not been able to make improvements and adjustments to the bone plate itself, and can only feed back relevant information to relevant medical devices businesses, and they make improvements. There are also big problems with the screws used to fix the bone plate in the traditional bone plate. the

Specifically, the contact parts of screws and screwdrivers currently used clinically are all hexagonal or P-shaped, that is, screwed in or out with a hexagonal or P-shaped screwdriver. When the physical and chemical properties of the screw change due to the long-term internal environment, there will be a "slipping" phenomenon in which the screwdriver slips on the nut, which directly leads to the failure of the screw to be removed. Highly difficult operations involving specialized instruments, sacrificing local bone mass, and prolonging operation time also bring about increased infection rates and the risk of intraoperative refracture. the

With the rise of 3D printing technology (also known as rapid prototyping technology), it is widely used in various fields of society, especially the impact on medical devices is revolutionary. Therefore, the market needs a bone plate using 3D printing technology to fill the gap in this market segment, so as to relieve the pain of fracture patients and obtain the best use effect. the
