| titleOfInvention | Multichannel nerve conduit and preparation method thereof |
| abstract | The invention provides a preparation method of a multichannel nerve conduit, which comprises the following steps: carrying out electrostatic spinning on a spinning solution of the shape memory material to obtain a double-layer fiber membrane with a random fiber layer and an oriented fiber layer which are sequentially superposed; cutting the double-layer fiber film into strips, rolling the strips on a glass rod to enable the oriented fiber layer to be in contact with the glass rod, and then processing the strips at high temperature to endow the strips with a tubular shape; then flattening at room temperature to keep the shape of the planar membrane; firstly, placing a small-size double-layer fiber membrane in a shape of a planar membrane at a deformation response temperature to change the small-size double-layer fiber membrane into a small-diameter conduit; and then placing a plurality of small-diameter catheters on the large-size double-layer fibrous membrane in the shape of the planar membrane, and placing the catheters at a deformation response temperature to form large-diameter catheters so as to obtain the multichannel nerve catheter. The preparation method has simple process, realizes the rapid self-molding of the three-dimensional multi-channel catheter by utilizing the shape memory of the shape memory material, and has good structural integrity. The invention also provides a multichannel nerve conduit. |
