Problems solved by technology

This operation has certain skills. If the operation is not done properly, the folded end of the silk thread cannot be left in the abdominal cavity, and the thread needs to be punctured again into the abdominal cavity.
[0010] 2. During the laparoscopic lens-assisted decoupling process, the lens may scratch the peritoneal tissue
[0011] 3. There is a water chestnut in the notch of the crochet needle point B
During the operation, the hernia hook needle enters the abdominal cavity and hooks the reflexed end of the silk thread, which easily damages the peritoneum, causing the peritoneum to rupture in the abdominal wall, and then easily leads to hernia recurrence
[0012] 4. The hernia hook hook hooks the reflexed end of the silk thread to the outside of the abdominal wall, and it is easy to get off the line. Once off the line, it needs to be punctured again, which increases the difficulty of the operation.

Embodiment 1

[0053] like Figure 5-22 As shown, the high-position ligation needle for the hernia sac includes the ligation needle, the pull rod 2 and the pull rod control mechanism.

[0054] The ligature needle includes a shaft part 11 , a handle part 12 and a needle point part 13 . The handle part 12 and the needle point part 13 are respectively connected to two ends of the rod part 11 . A rod hole 111 is formed on the rod portion 11 . A spring cavity 121 is disposed inside the handle portion 12 . The needle tip 13 is flat and has a notch 131 thereon.

[0055] The pull rod 2 is installed in the pull rod hole 111 , and its two ends protrude from the two open ends of the pull rod hole 111 respectively, and the upper end of the pull rod 2 extends into the spring cavity 121 . The pull rod 2 can reciprocate linearly in the pull rod hole 111, and then open or close the gap 131 on the needle tip 13. When the pull rod 2 closes the gap 131, a hole A3 for thread passing is formed between the pull...

Abstract

A hernial sac high ligature needle comprises a ligature needle and a pull rod; the ligature needle comprises a shank, a handle and a tip portion; the handle and the tip portion are connected respectively to two ends of the shank, the tip portion is flat and is provided with a gap, the pull rod is linked to the ligature needle and may reciprocate linearly relative to the ligature needle so as to open or close the gap in the tip portion, and hole A for passage of a thread is formed between the pull rod and the tip portion when the pull rod closes the gap. The hernial sac high ligature needle has the advantages that the functions of existing hernia needles and hernial bearded needles are combined to the single instrument, surgical steps are simplified, and surgical efficiency is improved; the gap in the tip portion is opened or closed by controlling the pull rod, lens assistance is not required in one-hole surgery, and auxiliary damage is reduced; it is convenient to dwell a thread in the abdominal cavity and pull it out of the abdominal cavity, surgical time is shortened, and surgical risk is reduced.

Description

technical field [0001] The invention relates to surgical instruments, in particular to a hernia sac high-position ligation needle. Background technique [0002] At present, in the high ligation operation of the hernia sac, two kinds of surgical instruments-the hernia ring needle and the hernia hook needle-are needed. The structure of the hernia ring needle is as figure 1 , 3 As shown, it includes a rod A5, a handle A6 and a needle point A7. The handle A and the needle point A are respectively connected to the two ends of the rod A. The needle point A is flat and has a hole 71 for the thread to pass through. Hernia crochet structures such as figure 2 , 4 As shown, it includes a rod B8, a handle B9 and a needle point B10. The handle B and the needle point B are respectively connected to the two ends of the rod B. The needle point B is flat and has a notch 101 for hooking the thread. [0003] The specific process of one-hole high hernia sac surgery in children is as follo...
