Tissue engineering bracket with partitions

Abstract

The invention relates to the technical field of human bioengineering, in particular to a tissue engineering bracket with partitions, the tissue engineering bracket comprises a bracket body, wherein the bracket body is composed of a plurality of groups of parallel net strips with different directions between each group, and reinforcing edges for interweaving and connecting the net strips are arranged between the net strips. A sparse structure area and a compact structure area are regularly arranged on the bracket body, and a transition structure area is arranged between the sparse structure area and the compact structure area. According to the tissue engineering bracket with partitions, a plurality of groups of parallel net strips with different directions between each group are connected to form a model with a specific shape through a plurality of reinforcing edges which are interval distributed and are generally connected with each other to form a rhombic shape, and the model is emphatically partitioned to enable different parts of the model to have different densities and strengths; an auricle bracket is manufactured by adopting a 3D printing titanium alloy method, so that the artificial auricle bracket is closer to the structure of a real auricle; the preparation is made for improving the conventional small-ear deformity auricle reconstruction operation, rib cartilage does not need to be intercepted through thoracic operation, and the pain of patients is relieved.

Description

technical field [0001] The invention relates to the technical field of human body bioengineering, in particular to a tissue engineering bracket with partitions. Background technique [0002] The basis of the treatment of congenital microtia is the reconstruction of the external auricle. The normal auricle is composed of thin skin soft tissue wrapped elastic cartilage support, has an elastic thin shell structure, and is composed of helix, antihelix, tragus, antitragus, earlobe, concha, triangular fossa, and scaphoid fossa Equal composition, convex and concave circles, complex shape, so auricle reconstruction is a difficult and complicated operation. At present, one of the main surgical methods used clinically is the brent-nagata method, that is, part of the patient's costal cartilage is cut out for splicing and carving to make the shape of the auricle, and the auricle reconstruction is performed in stages. [0003] Although auricle reconstruction can create a reconstructed ...

AI Technical Summary

Problems solved by technology

[0003] Although auricle reconstruction can create a reconstructed ear that is very similar to the normal auricle, there are many factors that affect the shape of the reconstructed ear, such as the tightness, thickness, and size of the residual ear and the skin behind the residual ear. These conditions will affect the surgical results. At the same time, taking the costal cartilage itself will cause great trauma to the patient, and the loss of the costal cartilage left after the operation will inevitably cause inconvenience to future life; in addition, as the difficulty of the operation, the length, shape, and thickness of the costal cartilage to be cut are different. It is very large, and the carving of costal cartilage is a great challenge to the surgeon's aesthetics and knife skills

Therefore, this operation has the characteristics of high difficulty, long operation time, and loss of multiple costal cartilages after operation.
