The utility model provides a novel medical sewing needle, see figure 1 and figure 2, novel medical sewing needle includes: a needle 10 and a suture 20. The suture needle 10 comprises an arc puncture needle 11 and a needle point 12 positioned at a first end of the puncture needle 11, wherein a needle hole 13 is formed in the needle point 12; the first end of the suture thread 20 is connected with the second end of the puncture needle 11 and the suture thread 20 can pass through the needle hole 13. In modern medicine, when a patient needs to perform direct-view suture in a blood vessel cavity, a hollow organ and the like, or perform lumen anastomosis butt joint, lumen rupture repair, hollow organ rupture repair and the like, due to unclear view in a lumen, such as a common suture method used in a surgical operation, the condition in the lumen has to be exposed through excessive operations, and the operation performed by exposing the inside of the lumen can be avoided through a puncture method, so that the exposure degree of the inside of the lumen is reduced as much as possible. When suturing such as rupture of hollow organs, planar tension-free suturing (i.e. large-area suturing) is required, when planar suturing is adopted, puncture is required from the inside of a tube cavity to the outside of the tube cavity, see fig. 3, at the moment, a suture needle 10 is punctured into the tube cavity from the outside of the tube cavity, a suture thread 20 is penetrated through a needle hole 13, one end of the suture thread 20 is arranged in the tube cavity, the other end of the suture thread is arranged outside the tube cavity, a puncture needle 11 is guided to reach the position to be sutured under the guidance of ultrasound or X-rays, the puncture needle 11 is punctured perpendicular to the wall of the tube cavity, the needle point penetrates out of the tube cavity, the suture thread 20 is conveyed out of the tube.

Further, referring to fig. 3 and 4, after the suture needle 10 is sleeved in the lumen of the suture thread 20 to form a first wave, the second end of the suture thread 20 is passed through the first wave, the suture needle 10 is continuously withdrawn into the lumen, then, the second wave is formed by passing the suture thread 20 out of the lumen again, then, the second end of the suture thread 20 is passed through the second wave again, the operation is repeated, the third wave and the fourth wave are formed in sequence until the wound of the patient is completely sutured, finally, the puncture needle 11 is separated from the suture thread 20 and withdrawn out of the lumen, then, the suture thread 20 is tightened, and the suture is knotted at the suture end, and the suture installation can be completed. The utility model discloses a punch through needle point 12 at sewing needle 10, when the doctor need carry out the face-like suture to the patient, can be fine carry out the puncture at the intracavity to can form the condition that can tighten up fast after the puncture, the operation degree of difficulty that significantly reduces, reduce the operation exposure time, and then reduce the patient because the operation produces the risk of further wound.

In a preferred embodiment, referring to fig. 1, the suture thread 20 is provided with a guide rod 21, after the suture thread 20 is sent out of the lumen to form a wave by multiple puncture of the suture needle 10, one end of the suture thread 20 outside the lumen needs to pass through one end formed by all the suture threads 20, and at this time, the guide rod 21 is needed to guide one end of the suture thread 20 outside the lumen to pass through the wave formed by the suture thread 20.

Wherein, the guiding rod 21 is arranged at the second end of the suture 20, particularly at the end of the second end of the suture 20, and can well guide the suture 20 to pass through the wave formed by the suture 20. Further, the guiding rod 21 is a cylinder, and in a preferred embodiment, the guiding rod 21 has a length of 10mm, a diameter of 0.4mm, a longer length and a thinner diameter, so that the suture 20 can be easily guided to pass through the wave formed by the plurality of sutures 20, and the operation time can be greatly reduced.

In addition, with continued reference to fig. 1, the end of the guiding rod 21 connected to the suture 20 is a round head, the other end of the guiding rod 21 is a pointed end, the round head of the guiding rod 21 can be conveniently linked with the suture 20, and the pointed end can enable the guiding rod 21 to better guide the suture 20 to pass through the wave formed by the suture 20, so that the situation that the edge angle hooks the suture 20 in the process of passing through the wave is avoided because of the edge angle.

The suture line 20 and the guide rod 21 are connected by an extrusion die, the suture line 20 and the guide rod 21 are attached together to form a smooth connection point, and in the operation process, the connection between the line and the guide rod 21 is particularly important, so that the guide rod 21 and the suture line 20 have certain connection strength, and any adhesive cannot be used, therefore, the connection between the guide rod 21 formed by the extrusion die and the suture line 20 can well meet the operation use requirements.

In a more preferred embodiment, the puncture needle 11 is in a semicircular arc shape, during the suture installing and suturing operation, the puncture needle 11 needs to puncture the lumen wall for multiple times, the semicircular arc-shaped puncture needle 11 can puncture the tube wall more easily, the suture thread 20 can be rapidly formed into a wave shape after completing one puncture, and meanwhile, the semicircular arc-shaped puncture needle 11 can be rapidly drawn out from the lumen after the puncture. Wherein, the semicircular arc shape refers to an arc with a central angle of 180 degrees.

Further, the cross section of the puncture needle 11 is circular, the puncture needle 11 with the circular cross section is more convenient to clamp, and can better move in the lumen, and the puncture needle 11 is not easy to damage the lumen due to the arc-shaped surface.

The suture thread 20 is a polypropylene thread with a smooth surface, and in a preferred embodiment, the selected polypropylene thread has the characteristics of high fiber strength, moderate elongation, low initial modulus, no toxicity, good biocompatibility and the like, so that the suture thread 20 has the characteristics of good uniformity, stability, no toxicity, no antigenicity, no carcinogenicity, gastric acid resistance, gastric digestive enzyme resistance and infection resistance, extremely small tissue reaction and the like, and meanwhile, the suture thread 20 also has various selectable lengths of 70mm, 90mm, 120mm and the like.

In addition, the suture 20 and the puncture needle 11 are connected by a squeeze forging die, the suture 20 and the puncture needle 11 are attached together to form a smooth connection point, and in the operation process, the connection of the suture 20 and the guide rod 21 is particularly important, so that the puncture needle 11 and the suture 20 have certain connection strength, and any adhesive cannot be used, therefore, the connection of the puncture needle 11 and the suture 20 formed by the squeeze forging die can well meet the operation use requirements.

The above description is only for the embodiment of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art.
