Problems solved by technology

[0003] The laparoscopic treatment of inguinal hernia in children is performed by inserting a poke card in the umbilicus as a laparoscopic observation port, and inserting a poke card in the lateral abdominal wall as an auxiliary operation hole, through the operation hole to assist the puncture needle lead wire, and the peritoneum needs to be punctured in the groin , exchange and guide the thread in the abdominal cavity, and perform high ligation of the hernia sac. This is the traditional two-hole surgical method. In this surgical method, the surgical incision scar at the umbilicus is easy to hide due to skin folds, but the surgical incision on the lateral abdominal wall is easy to form. Glaring scars, such as children with scar constitution, will leave thick scars
Traditional laparoscopic high ligation of the hernia sac in children requires intra-abdominal surgery. Peritoneal injury or organ damage may occur during the operation. There is a risk of abdominal adhesions and intestinal adhesions after surgery. In severe cases, intestinal obstruction and intestinal perforation may occur. serious complications

Embodiment 1

[0032] like Figure 1-Figure 6 As shown, a complete single-hole laparoscopic puncture needle assembly for children with hernia, including a handle 1, and also includes a guide needle, an auxiliary needle, and a hooking needle; the needle bodies of the introducing needle, the auxiliary needle, and the hooking needle all include a straight needle shaft 2 , arc needle bar 3 and needle head, one end of the straight needle bar 2 is connected with the handle 1, the other end of the straight needle bar 2 is connected to one end of the arc needle bar 3, and the other end of the arc needle bar 3 is provided with Needle, the head of the needle is blunt, and the whole body of the head of the needle has interlaced layered protrusions 7 .

[0033] In this embodiment, the guide needle plays the role of threading, sneaking in the preperitoneal space of the inner groin ring hernia sac neck to guide the surgical thread to a suitable position for standby; the auxiliary needle helps the guide ne...

Embodiment 2

[0035] like figure 1 and figure 2 As shown, Embodiment 2 is based on Embodiment 1. The needle head 4 of the lead needle is provided with a threading hole 8 , and the thread hole 8 radially penetrates the needle head of the lead needle 4 .

[0036] In this embodiment, there is a threading hole 8 on the needle head 4 of the lead needle, and the thread hole 8 is pierced with a surgical thread. The lead needle passes through a 2mm skin incision above the inner ring to puncture the abdominal wall and enter the preperitoneal space without puncturing the peritoneum. , sneak around the inner ring in the preperitoneal space clockwise or counterclockwise, and deliver the surgical thread to the designated area; during this process, the auxiliary needle assists the guide needle to create the pre-peritoneal space, and the needle 5 of the auxiliary needle is used to effectively separate the vas deferens and the peritoneum , to avoid mistakenly ligated the vas deferens.

[0037] The rest ...

Embodiment 3

[0039] like Figure 5 and Image 6 As shown, embodiment 3 is based on embodiment 2, and the needle head 6 of the hooking needle is provided with an open hook groove 9 near the outer arc, and the hook groove 9 is a bidirectional hook structure.

[0040] In this embodiment, during the operation, the hooking needle passes through an original skin incision above the inner ring, punctures the abdominal wall and enters the preperitoneal space without puncturing the peritoneum, and sneaks around the inner ring in the preperitoneal space along the lead needle. On the contrary, the clockwise sneaks, and the needle 6 of hook thread needle is provided with the hook groove 9 of opening near the outer arc, which is convenient to cooperate with the lead needle, and an end of the surgical thread that is worn in the needle 4 of lead needle 4 is hooked out of the body.

[0041] The rest of the structure and working principle of embodiment 3 are the same as embodiment 2.

Abstract

The invention discloses a complete single-hole laparoscopic puncture needle assembly for infantile hernia. The assembly comprises a handle, a lead needle, an auxiliary needle and a thread hooking needle; and the needle bodies of the lead needle, the auxiliary needle and the thread hooking needle respectively comprise a straight needle rod, an arc needle rod and a needle head, wherein one end of the straight needle rod is connected to one end of the handle in a detachable manner through threads; the other end of the straight needle rod is connected to one end of the arc needle rod; the needle head is arranged at the other end of the arc needle rod; the head of the needle head is blunt; and the whole body of the head of the needle head is provided with layered bulges which are overlapped ina staggered manner. The complete single-hole laparoscopic puncture needle assembly for infantile hernia disclosed by the invention has the advantages that the operation can be completed by adopting asingle-hole laparoscope, the wound is small, the operation anesthesia time is reduced, the risk is reduced, and the cost is saved. After operation, the abdominal wall is more beautiful, the peritoneumof the groin area is complete, and the assembly has the advantages of reducing damage, reducing the risk of abdominal cavity adhesion, reducing the risk of misligating the spermatic duct and the like.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a complete single-hole laparoscopic puncture needle assembly for hernia in children. Background technique [0002] At present, after the diagnosis of inguinal hernia in children is confirmed, surgical contraindications are excluded, and there are indications for surgery. In the past, open inguinal hernia and high ligation of the hernia sac were the main surgical methods. With the development of medical technology, laparoscopic high ligation of the hernia sac in children is currently used: due to its small trauma, short operation time and fast postoperative recovery, it has become the first choice for the treatment of inguinal hernia in children. [0003] The laparoscopic treatment of inguinal hernia in children is performed by inserting a poke card in the umbilicus as a laparoscopic observation port, and inserting a poke card in the lateral abdominal wall as an auxilia...
