Beschreibung
Zusammenfassung:	The invention discloses a bionic tendon sheath membrane and a preparation method, a spinning membrane forming process comprises the following steps: step 1, firstly, a cylindrical sleeve is filled with air, a layer of cylindrical membrane is formed on the cylindrical sleeve (130), and a side surface outside the membrane is formed; 2, negative pressure suction is conducted on the cylindrical sleeve (130), so that the radian of the part, between the side edges, away from the rotating shaft (110), of the supporting pieces, of the cylindrical sleeve (130) is larger than the diameter of the part expanded into a cylindrical surface; 3, spinning operation continues, the rotary drum rotates in a stepping mode, the cylindrical sleeve parts between the side edges of all the supporting pieces receive drawn wires one by one, a thick part is formed, the hyaluronic acid concentration of the part is 3%-80%, and the interior of the membrane is formed; after a thicker interior is formed in the part between every two supportin
