The invention discloses a fibrous ring suturing device used after lumbar disc herniation nucleus pulposus minimally invasive enucleation. The fibrous ring suturing device comprises a suture needle body and a suture thread, wherein the suture needle body comprises a guide needle thread and a guide needle sleeve; the guide needle sleeve is arranged on the guide needle thread in a sleeving manner and is limited by a limiting device on the guide needle thread; the suture thread is integrally connected with the guide needle thread through a suture thread connecting device. The fibrous ring suturing device is simple and reasonable in structure and easy to operate, can be used in the wound suturing process of a minimally invasive surgery, and can suture rupture surfaces with different shapes. Under the synergy of an aperture mirror, the entire operation is within a visible range, the process is safe and controllable, and the problems that after a nucleus pulposus enucleation under the conventional aperture mirror, the fibrous ring suturing process is complicated, low in efficiency and high in cost, consumes long time and is likely to cause secondary harm are solved.

The invention relates to an operation incision muscle suture needle, in particular to a laparoscope puncture incision muscle suture needle, which solves the problems of low suture efficiency, inflexible operation, and on the like caused by unreasonable structure of the traditional laparoscope incision muscle suture instrument. The suture needle is composed of a needle body and a handle on the tail end of the needle body, wherein the needle body is provided with a chute outwards hanging wires from the opening, and a chute inwards sending wires from the opening; the needle body is of an arc shape, of which the central angle is 30DEG; and the handle is in an H shape; and two cross bars of the H-shaped handle are perpendicular to the plane of the axis of the arc-shaped needle body. The invention improves suture efficiency, is flexible to operate, can realize efficient and quick suture to the muscle layer of deep small incisions at waists and abdomens for a retroperitoneal laparoscopic operation for obese patients, and can achieve the aims of preventing complications and obviously shortening the suture time of operation incisions. The invention has the advantages of simple structure, easy processing and manufacture and lower cost, and can be repeatedly used after cleaning and disinfecting.

The invention discloses a plate-making method for a one-piece type lapel. The plate-making method for the one-piece type lapel comprises the steps that extending 0.8a to an N point from a front collarwidth point S along a shoulder oblique line is carried out, the N point is connected to a lapel point M, and an original folding line MN is determined; the shape of the collar is reasonably designed,and meanwhile, the b is taken to a P point from the N point along the shoulder oblique line, and the shape of the front collar is designed according to the P point, and a serial port line QT is determined; a length is taken from a Q point to a T point along the serial port line to obtain an O point, the O point is connected with the N point, a turn-down collar folding line ON is determined, the Opoint is connected to an M point, and a lapel folding line OM is determined; the lapel fold line is taken as the center for the mirror image of the lapel, and the lapel is obtained; a mirror image ofthe front collar is obtained by using the lapel fold line as the center, and the mirror image P' of the P point is obtained; the P point and the P' point are connected to determine the shoulder stitch point connection line PP'; a parallel line of the turn-down collar folding line is made, and a lapel flat line O' N' is obtained; the lapel edge OT' is subjected to extending to intersect with the lapel flat line at a point C, and an arc is made between the point C and a point S to obtain a front neckline. The one-piece type lapel is fit and attractive.
