Preferably, needle body middle part outer wall is equipped with anti-skidding line, through be equipped with anti-skidding line at needle body middle part outer wall, the design of anti-skidding line for the user increases the frictional force with the finger when sewing up, prevents to skid, or the condition that drops, reaches the reliability that improves the sewing up.

Preferably, the two clamping needles are symmetrically arranged about the horizontal center line of the needle groove, and the two clamping needles are symmetrically arranged about the horizontal center line of the needle groove, so that the top ends of the two clamping needles abut against each other to form a structure which can not be pushed out.

Preferably, the needle body adopts plastic steel to make, adopts plastic steel to make through the needle body, when the user need adjust the arc and sew up the needle radian, can be appropriate crooked or throw straight arc and sew up the needle, reach the purpose of the degree of depth and the thickness of conveniently sewing up the tissue.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses, be equipped with the second cylinder through needle body right side inner wall, second cylinder outer wall parcel has the spring, spring outer wall is connected with first cylinder, first cylinder outer wall is connected with the card needle, when the user needs the threading, only need grasp the both ends of line, then aim at under the needle groove card, when blocking the needle position, get into the pinhole after pushing open the card needle, the first cylinder that links to each other with the card needle receives spring elastic potential energy and turns into the power of kinetic energy, resume initial position, two card syringe needle looks pinhole directions, so the card needle can not be opened to needle groove direction because of external force, the purpose that medical line can only not be advanced has been guaranteed, reach and improve threading efficiency, the purpose of facilitating the use.

2. The utility model discloses, through being equipped with anti-skidding line at needle body middle part outer wall, the design of anti-skidding line for the user increases the frictional force with the finger when sewing up, prevents to skid, or the condition that drops, reaches the reliability that improves the sewing up.
