Abstract

The invention discloses a method for constructing a segmental individualized human urethral three-dimensional scaffold material, which comprises using three-dimensional ultrasound technology to obtain the overall imaging information of the patient's thin-layer penis; using a manual outline method to screen out the overall imaging information to be constructed Image area: Use 3D technology to perform 3D reconstruction and processing of the image area to be constructed, import it into a 3D printer for printing, and prepare a urethral model, and then construct a material-fillable urethral model after the urethral model is reversed by a silica gel inversion process. Silicone model: the filling material is placed in the silicone model for reorganization, and a three-dimensional scaffold material of human urethra with individual characteristics is constructed. The solid model constructed by the technical solution of the present invention fits the physiological and anatomical position structure of the normal human urethra, conforms to the individual characteristics of the patient, and enables the constructed material to have the advantage of being adjustable in macroscopic and microscopic multi-scales.

Description

technical field

[0001] The invention belongs to the field of medical technology, and relates to a method for constructing medical human tissue scaffold materials, in particular to a method for constructing segmental individualization using three-dimensional ultrasonic imaging tools, three-dimensional printing technology combined with inverted film technology and biological material preparation technology A method for three-dimensional scaffolding materials of the human urethra. Background technique

[0002] In the past ten years, the attention paid to the treatment of urethral stricture in complicated cases is showing a trend of continuous heating up. Although the current clinical gold standard for urethral repair and replacement surgery is still to use various autologous tissues such as penile flap, buccal mucosa, tongue mucosa and even colonic mucosa for reconstruction. However, the introduction of the concept of tissue engineering in this field has caused more and more i...
