Claim 3:
4. A process for making the suture structure for medical surgery according to claim 1, comprising:
step S1, fixing the thread head core by arranging the plurality of thread core yarns side by side to form the thread head core, fixing two ends of the thread head core respectively on a positioning fixture and straightening the plurality of thread core yarns;
step S2, placing the suture connection yarn by fixing a first end of the connection section of the suture connection yarn, wherein the connection section extends and is attached to the thread head core along the length direction of the thread head core, and the second end of the suture connection yarn extends out from the thread head core at the middle of the thread head core;
step S3, winding the winding yarn by tying an end of the winding yarn on the thread head core or the positioning fixture, and spirally tensioning, and winding the winding yarn on the thread head core and the connection section, so that the thread head core and the connection section are tied to form the thread rod; and
step S4, detaching two ends of the thread rod from the positioning fixture; and cutting off redundant yarns;
wherein the positioning fixture comprises a support base plate and two positioning columns fixedly provided on the support base plate with space apart from each other, and a transverse wire hook is provided on each of opposite sides on a middle or a top of the two positioning columns, a transverse rubber block is provided on each of back sides, relative to the opposite sides, of the two positioning columns, a clamping groove is provided on each of the transverse rubber blocks, and the transverse wire hooks of the two positioning columns are arranged opposite to each other; a mounting column is provided on the support base plate close to one of the two positioning columns, and an alloy wire column is provided on a top end of the mounting column; the step S1 further comprises: winding one or more yarns on the transverse wire hooks back and forth to form the plurality of the thread core yarns; and the step S2 further comprises: winding the suture connection yarn for a plurality of turns in the clamping grooves of the transverse rubber blocks to secure the suture connection yarn.
