[0002] Hernia needle is a kind of medical equipment for treating hernia. Hernia, i.e. a certain organ or tissue in human body leaves its normal anatomical position, enters another part through weak point, defect or aperture formed by congenital or acquired. Common hernia includes umbilical hernia, inguinal hernia, indirect hernia, incisional hernia, surgical recurrent hernia, white line hernia, femoral hernia, etc. Among them, inguinal hernia is caused by increased intra-abdominal pressure due to reasons such as cough, sneezing, overexertion, abdominal obesity, forceful defecation, pregnancy, excessive crying of children, and regressive changes of abdominal wall strength in old age, forcing free organs in abdominal cavity such as small intestine, cecum, omentum, bladder, ovary and fallopian tube to enter another part through normal or abnormal weak point or defect or aperture. Hernia needle is usually used to repair inguinal or abdominal hernia.
[0003] Hernia needle surgery is a minimally invasive treatment method, which does not need large incision or mesh implantation. In this surgery, the doctor hooks the suture with hernia needle in preperitoneal space under laparoscope, hooks around the inner ring of hernial sac for one turn, tightens the suture and knots it under the skin, so as to achieve the purpose of high ligation of hernial sac.

DETAILED DESCRIPTION
[0028] The following specific embodiments illustrate the implementation of the present application, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification.
[0029] Please refer to Figs. 1-5 . It is understood that the structure, proportion, size, etc. shown in the drawings attached to the specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the implementation conditions of the present application, so they do not have technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" in the specification are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship, without substantially changing the technical content, is also considered as the scope of the present application.
[0030] The present application discloses a hernia needle assembly, as Figs. 1-5 shown, the hernia needle assembly comprises a puncture member 10 and a lead member 20; the lead member 20 comprises an elongated section 21, and the end of the elongated section 21 is formed with a deformation part, and the deformation part is formed with a wire locking hole 211; the puncture member 10 is formed with a channel for the lead member 20 to axially pass through. The present application combines the lead member 20 with the puncture member 10, locks the wire through the wire locking hole 211, realizes the convenient and safe use of the hernia needle assembly, and improves the efficiency and quality of the hernia operation.
[0031] In one specific embodiment, as Figs. 1-2As shown in Figure 4, the elongated segment 21 is also axially connected to a limiting protrusion segment 22, which protrudes radially relative to the elongated segment 21. The radially protruding limiting protrusion segment 22 is used to limit the axial length of the elongated segment 21 extending into the puncture member 10, preventing excessive insertion and facilitating positioning and removal.
[0032] In one specific embodiment, a surgical suture 23 is used in conjunction with the hernia needle assembly during hernia surgery. The surgical suture 23 is folded in half and passed through the locking hole 211, which engages with the puncture member 10 to lock or release the surgical suture 23.
[0033] In a more specific embodiment, the surgical suture 23 is a non-absorbable surgical suture. In a similar embodiment... Figs. 1-2 In the specific embodiment shown, the surgical suture 23 is a mousse suture.
[0034] In a more specific embodiment, such as Figs. 1-4 As shown, along the direction away from the elongated segment 21, the limiting protrusion 22 further includes a sliding limiting segment 221 and a handle 222, and the channel is formed with a limiting segment 12 that matches the sliding limiting segment 221. The sliding limiting segment 221 matches the limiting segment 12, limiting the sliding range of the sliding limiting segment 221 to the range of the limiting segment 12, making the use of the hernia needle assembly more controllable.
[0035] In a more specific embodiment, such as Figs. 1-4 As shown, the channel includes a deformable limiting section 111, which is used to close the locking hole 211. During abdominal paracentesis, the hernia needle assembly... Fig. 2 As shown, the locking hole 211 is located inside the limiting section 111 of the deformable part. When the locking hole 211 is closed, the surgical suture 23 inside the locking hole 211 is locked and brought into the channel, so that the surgical suture 23 will not fall off during the puncture. After the puncture is completed, the surgical suture needs to be released in the abdominal cavity to complete the wrapping suture. The locking hole 211 is exposed in the limiting section 111 of the deformable part. When the locking hole 211 is opened, the surgical suture 23 inside the locking hole 211 is released, making it easy for the doctor to retrieve the suture.
[0036] In one specific embodiment, such as Figs. 1-3 As shown, the outline of the locking hole 211 is selected from one of the following: rhombus, circle, and ellipse.
[0037] In a like Figs. 1-3 In the specific embodiment shown, the locking hole 211 is rhomboid. Further, the side length of the rhombus is 0.4 to 1 cm, and the interior angle of the rhombus is 30 to 150°.
[0038] In one embodiment as shown in Figs. 1-4 The axial length of the elongated section 21 is greater than the length of the deformation limiting section 111, so that the deformation section can be exposed from the channel.
[0039] In one embodiment as shown in Figs. 1-2 The puncture member 10 is a hollow needle tube 11, and the end of the hollow needle tube 11 is formed with a needle tip 112 for puncture.
[0040] In one embodiment as shown in Fig. 5 The end edge of the needle tip 112 is arc-shaped. The needle tip 112 with an arc-shaped end edge is not easy to scratch other tissues in the abdominal cavity, ensuring the safety of the operation.
[0041] In one embodiment as shown in Figs. 1-2 The length of the hollow needle tube 11 is 10-15 cm. The length of the hollow needle tube 11 can be 10 cm, 12 cm, 13 cm, 14 cm, or 15 cm. The length of the hollow needle tube is suitable for children of different ages, and has a wide range of applications.
[0042] In one embodiment as shown in Figs. 1-2 The hollow needle tube 11 is provided with a scale mark 113. The scale mark 113 on the hollow needle tube 11 makes the depth of needle insertion clear and controllable, without relying on experience, and reduces the difficulty of the operation.
[0043] In one embodiment as shown in Figs. 1-3 The elongated section 11 is a stainless steel wire.
[0044] In summary, the lead member and the puncture member are combined, the wire is locked through the wire locking hole, the hernia needle assembly is conveniently and safely used, and the efficiency and quality of the hernia operation are improved.
[0045] In summary, the lead member and the puncture member are combined, the wire is locked through the wire locking hole, the hernia needle assembly is conveniently and safely used, and the efficiency and quality of the hernia operation are improved.
[0046] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should be considered as the protection range of the present application.
