The radian of the needle point, the needle body and the needle tail are all 40 degrees and the lengths are all the same, and the sewing needle can insert and sew more conveniently through the arc needle point, the needle body and the needle tail.

In a further technical scheme, the distance value between the central point of the circular arc of the needle body and the connecting line of the two end points of the needle body is smaller than 10mm, so that the suture needle can freely enter and exit a 1.0cm poking card used in the abdominal cavity operation, the width of the poking card does not need to be additionally designed, additional punching is not needed, the wound is increased, and the wound of the minimally invasive operation is smaller.

In a further technical scheme, the cross section of the needle tail along the arc direction of the needle tail is hexagonal, and a needle hole for threading is formed in the tail end of the needle tail.

The needle tail rotates 60 at every turn and accords with more directly perceived impression and operation under the peritoneoscope, can rotate the needle tail more, and the position of adjustment needle point carries out diversified sewing, and needle tail hexagon takes more stably not easy slip simultaneously, improves and sews up efficiency.

The utility model has the beneficial effects that:

1. the utility model is suitable for laparoscope, has simple structure and is beneficial to suture;

2. the radian of the needle point, the needle body and the needle tail are all 40 degrees and the lengths are all the same, and the sewing needle can be inserted and sewn more conveniently through the arc-shaped needle point, the needle body and the needle tail;

3. the height of the needle body is less than 1cm, so that the suture needle can freely enter and exit the 1.0cm poking card used in the abdominal cavity operation, the width of the poking card does not need to be additionally designed, additional punching is not needed, the wound is increased, and the wound of the minimally invasive operation is smaller;

4. the needle tail rotates 60 degrees at every turn and accords with more directly perceived impression and operation under the peritoneoscope, can diversely sew up, and needle tail hexagon takes more stably difficult slip simultaneously, improves and sews up efficiency.
