[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] Example: Figure 1 , 2 As shown in Figures 3 and 4, the fascia suturing device of this embodiment comprises an operating rod 1, two puncture needles 2, a suture thread 3 and two elastic limit heads 4, one end of the operating rod 1 is provided with a connecting section 11 with a diameter smaller than that of the operating rod, a movable ring 12 is provided on the outer sleeve of the connecting section 11, a cylindrical cavity is provided inside the connecting section 11 and the operating rod 1, guide grooves 111 are provided on opposite sides of the connecting section 11 along its length direction, a nut 13 is provided at a position corresponding to the connecting section 11 in the cylindrical cavity, protrusions 131 passing through the guide grooves 111 are provided on both sides of the nut 13, the protrusions 131 are connected and fixed to the inner side of the movable ring 12, and both sides of the end of the connecting section 11 away from the operating rod 1 are respectively hinged with A connecting arm 14, one end of the connecting arm 14 away from the connecting section 11 is hinged with a rectangular limit frame 15, an elastic membrane is provided in the limit frame 15, one end of the limit frame 15 away from the connecting arm 14 is hinged with the movable ring 12, a screw 5 is provided in the operating rod 1, one end of the screw 5 is screwed with the nut 13, and the other end passes through the other end of the operating rod 1 and is rotatably connected to each other, the needle end of the puncture needle 2 is respectively embedded with one of the limit heads 4, the puncture needle 2 is provided with a push rod 21 that passes through the needle tail end, and the side walls on both sides of one end of the operating rod 1 are provided with guide needle grooves 16 with opposite inclined directions, and the two ends of the suture 3 are respectively connected with the two limit heads 4.

[0026] The usage process is as follows:

[0027] The end of the operating rod 1 provided with the connecting section 11 is passed through the puncture hole and enters the abdominal cavity. Then, the operating screw 5 is rotated to make the nut 13 move axially relative to the screw 5, thereby pushing the two limit frames 15 and the connection point of the connecting arm 14 to expand outward until the limit frame 15 is perpendicular to the operating rod 1 (when the nut 13 is set to have the maximum displacement, the limit frame 15 is just flattened). Then, the operating rod 1 is slightly moved outward so that the flattened limit frames 15 on both sides of the operating rod 1 are respectively fitted with the fascia (indicated by A in the figure) on both sides of the suture opening (in this state, the guide needle grooves 16 on both sides of one end of the operating rod 1 are inclined to point to the elastic membrane in the flattened limit frame 15 on the corresponding side); a limit head 4 is connected to each end of the suture line 3, and the limit heads 4 are respectively embedded in the two puncture holes. The needle end of the needle 2 is used to puncture the abdominal wall along the two needle guide grooves 16 (a mark line can be set on the puncture needle 2 to judge whether the abdominal wall is passed through according to the mark line indication, or according to the resistance). After puncturing the abdominal wall, the needle tip of the puncture needle 2 passes the elastic membrane in the limit frame 15 with the limit head 4 level thread head, and then the push rod 21 is operated to push the limit head 4, and the limit head 4 restores a certain shape and is blocked by the elastic membrane and cannot be withdrawn. The puncture needle 2 is pulled out of the original path, and then the screw 5 is operated to rotate in the opposite direction to reduce the expansion angle of the limit frame 15 to almost close to the connecting section 11, and then the operating rod 1 is withdrawn from the puncture hole to the outside of the body, and the two ends of the suture 3 and the limit head 4 are taken out at the same time, and the limit heads 4 at both ends are cut off, and the knot is tied and tightened to complete the suturing of the fascia. In the whole process, there is no need to rotate the operating rod 1, and the fascia on both sides of the suture can be threaded at the same time, and the fascia can be quickly sutured, which effectively shortens the suturing process.

[0028] In this embodiment, a knob 51 is provided at the other end of the screw rod 5 , and the screw rod 5 is easily rotated by the knob 51 .

[0029] In this embodiment, the other end of the screw rod 5 is provided with a straight section (without threads on the surface), which passes through a hole adapted for the other end of the operating rod 1. A tiny bearing for rotatably assembling the straight section can be set in the hole, and the bearing can be assembled with the hole.

[0030] In this embodiment, a handle is provided at the other end of the operating rod 1 , so that the operating rod 1 can be driven by holding the handle.

[0031] In this embodiment, the two opposite sides of the connecting section 11 are parallel planes, and the connecting arm 14 is a strip-shaped sheet member.

[0032] In this embodiment, the end of the connecting section 11 away from the operating rod 1 is spherical to prevent the tip from piercing tissues in the body.

[0033] In this embodiment, Figure 5As shown, the needle end of the puncture needle 2 is provided with a blind hole, and a through hole is provided inside the blind hole to penetrate to the bottom of the blind hole. The push rod 21 is installed in the through hole, and the limit head 4 is installed in the blind hole and can be pushed out of the blind hole. It is easy to install the limit head 4 well. The limit head 4 is compressed and embedded in the blind hole during assembly. The design of the through hole is also conducive to operating the push rod 21 to push out the limit head 4.

[0034] In this embodiment, the through hole and the blind hole are coaxially distributed, and the diameter of the push rod 21 is the same as the diameter of the through hole (or slightly smaller than the diameter of the through hole) to prevent the push rod 21 from shaking.

[0035] In this embodiment, a needle handle 22 is provided at the other end of the puncture needle 2 , so that the puncture needle 2 can be conveniently operated by holding the needle handle 22 .

[0036] In this embodiment, a pressing piece 23 is provided at one end of the push rod 21 that passes through the needle tail of the puncture needle 2. The design of the pressing piece 23 facilitates applying a thrust to the push rod 21.
