[0025] The disposable needle-thread embedded needle in this embodiment comprises a puncture needle 1, a push rod 2 and a lock 3. The push rod 2 and the lock 3 are both mounted on the puncture needle 1. The puncture needle 1 is covered with a jacket 4. A foam pad 5 is provided at the needle tip of the needle body 11 for preventing the thread body 6 from falling off. The thread body (6) is catgut, collagen thread or absorbable polymer thread (PGA, PDO, PGLA), etc.
[0026] The puncture needle 1 in this embodiment includes a needle body 11, a needle seat 12 and a cone seat 13. The needle seat 12 and the cone seat 13 are arranged as an integral or split structure. When the needle seat 12 and the cone seat 13 are arranged as an integral structure, the needle seat 12 and the cone seat 13 are integrally processed and formed. When the needle seat 12 and the cone seat 13 are arranged as a split structure, the needle seat 12 and the cone seat 13 are fixed by a snap-fit structure. The needle body 11 is fixed to the cone seat 13, and the cone seat 13 is fixed to the needle seat 12. The lock 3 includes a lock body 31, an elastic sheet 32, a card block 33 and a card slot 34. The elastic sheet 32 is fixed to the lock body 31, the card block 33 is fixed to the elastic sheet 32, and the card slot 34 is arranged on the needle seat 12. The card block 33 cooperates with the card slot 34, and a pinching groove 35 is provided on the lock body 31.
[0027] The push rod 2 in this embodiment includes a push rod seat 21, a guide rod 22 and a push rod flat-head needle 23. The push rod seat 21 is fixed to the guide rod 22, and the guide rod 22 is fixed to the push rod flat-head needle 23. The guide rod 22 and the push rod flat-head needle 23 are both located in the needle body 11.
[0028] The outer sleeve 4 in this embodiment includes an outer sleeve body 41 and a support sleeve 42 . The support sleeve 42 is fixed in the outer sleeve body 41 , and the support sleeve 42 contacts the conical seat 13 .
[0029] Specifically, the disposable needle-and-thread embedded needle has the thread 6 pre-placed in the needle body 11 before leaving the factory. The foam pad 5 provided in the needle tip of the needle body 11 can fix the thread 6. At the same time, a lock 3 is provided between the cone seat 13 and the push rod seat 21 to support the push rod 2. When in use, the human body is punctured through the needle body 11, the foam pad 5 is pulled out, and the pinching groove 35 is pinched with the fingers. Since the elastic sheet 32 is elastic, the lock body 31 can be pulled out, so that the card block 33 slides out of the card slot 34. Since the length of the lock body 31 is greater than or equal to the length of the thread 6, the push rod seat 21 can be pressed at this time to push the thread 6 out of the needle body 11 and into the body through the push rod flat-head needle 23.
[0030] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is merely an example of the structure of the utility model.
