The following describes an embodiment of a fascia suture instrument according to the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1, the application provides an fascia suture instrument, which comprises a thread taking rod 1, a suture thread 2 and a puncture needle 3, wherein a limit bracket 11 is arranged at the end part of the thread taking rod 1, a puncture targeting channel 112 is arranged at one side of the limit bracket 11, which is in contact with fascia, and an elastic sleeve 12 is sleeved outside the puncture targeting channel 112; the two ends of the suture 2 are provided with a limiting head 21, the limiting heads 21 can be clamped at the end part of the puncture needle 3, and the limiting heads 21 are left at the other side of the elastic sleeve 12 when the puncture needle 3 passes through the elastic sleeve 12.

It will be appreciated that the puncture needle 3 has a pointed end which can be passed through the fascia and the elastic sheath 12, and that the puncture needle 3 is engaged with the stopper 21 of the suture 2, so that one end of the suture 2 can be brought together through the fascia and the elastic sheath 12. At this time, the puncture needle 3 is separated from the stopper 21 of the suture thread 2, and the stopper 21 of the suture thread 2 is stopped by the elastic sheath 12 and remains on the other side of the elastic sheath 12, i.e., the side away from the fascia, when the puncture needle 3 is withdrawn, because of the ability of the elastic sheath 12 to recover the deformation. Rotating the suture taking rod 1 to the position where the other side of the puncture hole needs to be relatively sutured, connecting the limiting head 21 at the other end of the suture line 2 with the puncture needle 3, repeating the above operations, enabling the puncture needle 3 to drive the other end of the suture line 2 to penetrate through the fascia and the elastic sleeve 12 at the other side of the puncture hole, and at the moment, both ends of the suture line 2 are clamped at the other side of the elastic sleeve 12. The suture taking rod 1 is moved out of the puncture hole, the two ends of the suture line 2 are taken out by the puncture needle 3 at the moment, the limiting heads 21 at the two ends of the suture line 2 are cut off, the two ends of the suture line 2 are tensioned, so that the skins at the two sides of the puncture hole are tightly attached and closed, and knotting and fixing are carried out, so that the puncture hole is sutured.

In this case, the elastic sheath 12 is an elastic sheath and can completely cover the puncture target channel 112, and it should be noted that the elastic sheath 12 is in a stretched state in order to facilitate the penetration of the puncture needle 3. The limiting bracket 11 is in contact with the fascia, so that the puncture needle 3 can be positioned to pass through a preset position of the fascia, and meanwhile, the fascia is supported to a certain extent, so that the puncture needle 3 can conveniently pass through. The diameter of the thread taking rod 1 is about 4mm, and hard material parts are adopted, so that the thread taking rod has enough strength.

In some alternative embodiments, as shown in fig. 2, the puncture needle 3 comprises a needle tube 31 and a push rod, the end of the needle tube 31 is used for clamping the limiting head 21; the pushing rod is slidably arranged in the needle tube 31 for pushing the limiting head 21 to separate from the needle tube 31.

In this example, the length direction of the limiting head 21 forms an angle with the length direction of the suture thread 2, the limiting head 21 is clamped at the end of the needle tube 31, and an avoiding groove for the suture thread 2 to pass through is formed at one end of the needle tube 31 clamped with the limiting head 21, so that the needle tube 31 drives one end of the suture thread 2 to pass through the fascia and the elastic sleeve 12, and interference caused by the suture thread 2 in the passing process is avoided.

It can be understood that the pushing rod moves toward the stopper 21 in the needle tube 31 and abuts against the stopper 21, and the stopper 21 is pushed out from the needle tube 31 by further pushing the pushing rod.

Further, the needle tube 31 includes a piercing end and a holding end 311, the piercing end is used for clamping the limiting head 21, and the diameter of the holding end 311 is larger than that of the piercing end.

The holding end 311 is provided to facilitate the operation of the puncture needle 3 by the medical staff, so that the puncture needle 3 can easily pass through the fascia and the elastic sheath 12.

Preferably, the holding end 311 of the needle tube 31 is provided with a long hole 32 along the axial direction of the needle tube 31, the pushing handle 33 is slidably disposed in the long hole 32, and one end of the pushing handle passes through the long hole 32 and is connected with the pushing rod.

In this embodiment, the pushing handle 33 is further provided with an anti-slip protrusion at the end outside the needle tube 31 for increasing the friction force during pushing.

In some alternative embodiments, the outer wall of the thread take-off rod 1 is provided with a plurality of guide limiting grooves 13 at intervals facing the acupuncture target channel 112 for limiting the direction of the puncture needle 3 puncturing to the acupuncture target channel 112.

It can be understood that the puncture needle 3 passes through the fascia and the elastic sleeve 12 and passes through the puncture target channel 112 located in the elastic sleeve 12, but due to the skin occlusion, the specific position of the elastic sleeve 12 and the puncture target channel 112 cannot be found by observation during the puncture process, so that the puncture path of the puncture needle 3 needs to be accurately positioned. The guide-limiting groove 13 is thus provided so that the puncture needle 3 can be slidably fitted into the guide-limiting groove 13 and pass through the elastic sheath 12 and the puncture target passage 112 in the direction of the guide-limiting groove 13.

In this example, 2-3 guide limit grooves 13 are provided at intervals along the axial direction of the thread take-up shaft 1. The inner diameter of the guide limiting groove 13 is matched with the outer diameter of the puncture needle 3. Different guide limiting grooves 13 have different inclination angles, but it should be noted that the central extension lines of all the guide limiting grooves 13 are required to point to the direction of the needling target channel 112 on the thread taking rod 1.

The purpose of setting up a plurality of direction spacing grooves 13 is, adapts to different patient's stomach wall, and when the stomach wall is thinner, low-order direction spacing groove 13 exposes, just uses low-order direction spacing groove 13, and when the stomach wall was thicker, high-order direction spacing groove 13 exposes, just uses high-order direction spacing groove 13 to more accurate suture puncture hole.

In this example, the side wall of the puncture needle 3 is provided with identification lines corresponding to the plurality of guide stopper grooves 13 one to one. When the marking line reaches the guide limiting groove 13, the puncture needle 3 is shown to be punctured in place.

As shown in fig. 3, in some alternative embodiments, the limiting bracket 11 includes two limiting rods 111 and a folding rod 113, one end of the folding rod 113 is connected to the thread taking rod 1, the two limiting rods 111 are disposed at the other end of the folding rod 113 in parallel and spaced to form a needle-punching targeting channel 112, and a plane on which the two limiting rods 111 are disposed forms a set angle with the axial direction of the thread taking rod 1.

In this embodiment, the two position-limiting rods 111 are located near the fascia, and one end of the two position-limiting rods 111 far away from the folding rod 113 is spaced from the suture taking rod 1 by a predetermined distance, so as to facilitate the replacement of the elastic sleeve 12. The elastic sleeve 12 is sleeved outside the two limiting rods 111 to seal the acupuncture target passage 112 formed by the two limiting rods 111 at intervals. The spacing between the two stop rods 111, i.e., the width of the needle target passage 112, is such that the puncture needle 3 and the stop head 21 can pass through them.

In some alternative embodiments, the two stop levers 111 are perpendicular to the wire-taking rod 1, and the folding lever 113 forms an acute angle with the wire-taking rod 1. In this example, the folding bar 113 is integrally formed with the thread take-up lever 1.

The arrangement has the advantages that the limiting bracket 11 formed by the folding rod 113 and the limiting rod 111 can conveniently pass through a small puncture hole, and secondary damage to a patient can be avoided; the operation of medical staff is facilitated, and fascia needing to be sutured can be supported and positioned by rotating the limiting bracket 11 around the thread taking rod 1.
