The existing fascia suture device is characterized in that the front end of the puncture needle is simply provided with a clamping position for fixing the needle head of the suture line 2, the clamping position for fixing the needle head at the front end of the puncture needle cannot guarantee the strength during puncture, the clamping position for fixing the needle head of the puncture needle and the needle head of the suture line 2 during puncture is likely to be deformed due to the large resistance of a fascia layer, and the needle head is led to change towards the direction and even directly cause the falling of the needle head connected with the suture line 2. And when the puncture needle needs to be pulled out of the needle head of the suture line 2 after penetrating through the silica gel layer, the situation that the puncture needle cannot be pulled out directly and simultaneously can be caused, the operation is unstable, and the risk born by a patient is large.

3. Pterygoid lamina 3 uses into pinhole 4 to connect the structure that via hole 6 connects fender groove 5, and the cooperation keeps off the effect that position post 11 can effectually play the fender position, and the axial all keeps the puncture that can guarantee stably with pjncture needle passageway 16 coaxial line simultaneously, cancels traditional silica gel layer structure and can effectually avoid appearing the hole because the silica gel layer pierces through and lead to weakening the power of grabbing of syringe needle or stylolite 2 to influence the life of manadesma stitching instrument. The utility model discloses the improvement that can be very big is compared and is used the number of times, and the effect can guarantee stably all the time. Meanwhile, the thread passing seam 7 at the side of the wing plate 3 can facilitate the separation of the suture thread 2 from the wing plate 3.

4. The trunking 12 with a certain depth, which is axially arranged on the wall of the pipe orifice at the opposite side of the puncture point of the puncture incision of the puncture tube, can be matched with the pipe wall to relatively fix the gear column 11 to prevent the falling-off condition when the suture thread 2 is tensioned and straightened.

5. The stop column 11 adopts a dumbbell-shaped circular columnar structure with thick ends and thin middle parts to match with the suture line gradual-changing groove 13 to be deviated to one side, so that the stop column 11 is in a slightly inclined horizontal state with one end slightly higher than the other end slightly lower when being hung, the inclined state is basically consistent with the inclined state of the bottom surface of the stop groove 5 of the wing plate 3, and the possibility that the stop column 11 slides out from the through hole 6 can be avoided due to the inclined state. Simultaneously stylolite gradual change groove 13 adopts the gradual change can so that broad one side penetrates stylolite 2, moves to stylolite 2 of thinner one side and is pressed from both sides tightly, cooperates two stylolite passageways that the internal diameter is not of uniform size to play with the fixed effect with pressing from both sides tightly of stylolite 2 screens, guarantees the stability of gear post 11 when hanging.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
