Restoring titanium mesh

Abstract

The invention discloses a restoring titanium mesh. The restoring titanium mesh is used for remedying bone defects in a knee joint replacement surgery. The restoring titanium mesh (1) comprises horizontal ridge belts (2) for implanting the restoring titanium mesh into a human body and vertical ridge belts (3) for supporting the horizontal ridge belts (2). The horizontal ridge belts (2) and the vertical ridge belts (3) are intersected and combined to form a meshy restoring titanium mesh (1). According to the restoring titanium mesh, the meshy structure of the restoring titanium mesh can ensure the bone ingrowth of a patient and can be cut to provide a good matching rate for the patient so as to meet the requirements of the patient and can well ensure the bone ingrowth of the patient to be favorable for the later recovery of the patient, devices which are used in a matching mode are less, the operation time is reduced, the usage of intervention materials is reduced, the weight is reduced to be favorable for restoration of a defect portion of the bone, and the restoring titanium mesh is not only replacement of a prosthesis, can deal with cases under various special circumstances and is favorable for performing the operation smoothly.

Description

technical field [0001] The invention relates to a medical prosthesis, in particular to a revision titanium mesh that can make up for bone defects in knee joint replacement operations. Background technique [0002] The revision titanium mesh is an implantable prosthesis in knee joint replacement surgery. Its main function is to make up for the bone defect of the patient. The existing technology at home and abroad mainly uses the revision block in the operation to make up for the bone defect. The revision block is mainly composed of shape Different solid structures are composed to adapt to different patients with bone defects. The revision block is mainly used in revision surgery and primary surgical replacement with severe bone defects. With the increase of revision cases in clinical operations in our country, the application of revision blocks has gradually increased, and some shortcomings of revision blocks have also been exposed. [0003] At present, in the Chinese market...

Problems solved by technology

[0003] At present, in the Chinese market in knee joint surgery replacement is mainly used to make up for bone defects is the revision metal spacer, the metal spacer is mainly a solid structure produced and processed from titanium alloy or a 3D printed trabecular bone structure, among which Screw holes will be added at the site for fixing on the knee prosthesis, but this kind of structure is relatively bulky, which is not conducive to the ingrowth of bones, and is not conducive to the recovery of patients. Due to the fixed specifications of the metal spacer, it cannot meet the needs of patients with severe bone defects.

[0004] However, the existing problems of the repaired titanium mesh used at this stage are: the repaired titanium mesh is a mesh structure, which is not as stable as the solid structure, and is prone to breakage. The stress of the mesh structure is relatively concentrated, and the strength of the supporting column is higher. The net is relatively difficult in the production and processing process, and it is not easy to produce in batches
