Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a laparoscopic-assisted needle device for treating pediatric indirect inguinal hernia. Background Art

[0002] Inguinal hernia in children is a common and frequently-occurring disease in children, belonging to a congenital disorder. The main cause is the incomplete closure or non-closure of the congenital processus vaginalis peritonei. Only high ligation of the hernial sac is required to achieve the curative effect. With the development of minimally invasive surgery, its treatment method has gradually changed from traditional open surgery to laparoscopic minimally invasive surgery.

[0003] Chinese Patent Authorization Publication No.: CN204797948U discloses a needle forceps. This needle forceps can not only achieve the conventional grasping function, but also the forceps head can have the functions of puncture and perforation in the closed state; it can be operated with one hand, and a locking device is added to the handle part to avoid the situation that the forceps head loosens after the operator releases the handle, which is especially suitable for the operation of single-port laparoscopic treatment of pediatric inguinal hernia.

[0004] In the above-mentioned needle forceps during laparoscopic surgery, the opening and closing actions of a pair of forceps heads are used to achieve the effects of separation and grasping. However, during the opening process of a pair of forceps heads, if the distance between the forceps head and the tissue is not accurately controlled or there is not enough vision, the end of the forceps head may contact the intra-abdominal tissue, resulting in tissue compression, extrusion or stab wounds.

[0005] Therefore, a laparoscopic-assisted needle device for treating pediatric indirect inguinal hernia is proposed for the above problems. Summary of the Utility Model

[0029] Embodiment:

[0030] Please refer to Figures 1 - 3, A laparoscopic-assisted needle device for treating indirect inguinal hernia in children, including an outer tube 1. One end of the outer tube 1 is fixedly connected with a fixing block 2, and a grasping component 4 is provided at the end of the outer tube 1 away from the fixing block 2. A driving component 3 is provided at the end of the fixing block 2 away from the outer tube 1;

[0031] The grasping component 4 includes a pair of first movable blocks 41 and a pair of second movable blocks 42. Both of the pair of first movable blocks 41 are rotatably connected to the outer tube 1. One end of the first movable block 41 is integrally formed with a mounting block. One end of the second movable block 42 is provided with a mounting groove. A rotating shaft 44 is fixedly penetrated through the mounting block. Both ends of the rotating shaft 44 are respectively rotatably connected to the inner wall of the mounting groove. A torsion spring 45 is sleeved outside the rotating shaft 44. Both ends of the torsion spring 45 are respectively fixedly connected to the mounting block and the inner wall of the mounting groove.

[0032] This solution is an auxiliary tool in laparoscopic surgery for treating indirect inguinal hernia in children. It can not only achieve the conventional grasping function, but also has the functions of puncture and perforation. The tissue trauma is small, and it is especially suitable for pediatric surgery.

[0033] Specifically, the medical staff can hold the grip ring 32, penetrate the abdominal wall through the first movable block 41 and the second movable block 42 in the closed state, and can control the opening and closing actions of the pair of first movable blocks 41 and the second movable block 42 through the driving component 3 to achieve the effects of separation and grasping. When the grasping component 4 performs an opening action and the pair of second movable blocks 42 come into contact with the intra-abdominal tissue, the second movable block 42 and the first movable block 41 will rotate relatively to provide avoidance and reduce the probability of damage to the intra-abdominal tissue. In addition, by setting a torsion spring 45, when the second movable block 42 and the first movable block 41 rotate relatively, the torsion spring 45 will contract. When the second movable block 42 is separated from the intra-abdominal tissue, it can provide a restoring force to the second movable block 42 to make it reset.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 4 , The driving component 3 includes a pair of connecting handles 31. Both of the pair of connecting handles 31 are rotatably connected to the outer end of the fixing block 2. And both ends of the pair of connecting handles 31 away from the fixing block 2 are integrally formed with grip rings 32. A transmission rod 5 is slidably connected inside the outer tube 1. The transmission rod 5 penetrates through the fixing block 2 and is fixedly connected with a second connecting block 8. The outer end of the connecting handle 31 is rotatably connected with a first connecting rod 33. One end of the first connecting rod 33 away from the connecting handle 31 is rotatably connected with the second connecting block 8. A spring 7 is sleeved outside the transmission rod 5. Both ends of the spring 7 are respectively fixedly connected to the second connecting block 8 and the fixing block 2.

[0035] In this embodiment, when the medical staff pinches the pair of grip rings 32 to control the pair of connecting handles 31 to move closer to each other, the pair of first connecting rods 33 can be used to control the second connecting block 8 and the transmission rod 5 at the outer end to move.

[0036] Among them, during the movement of the second connecting block 8 and the transmission rod 5 at the outer end, the second connecting block 8 can compress the spring 7, and the spring 7 can use its own elastic force to make the connecting handle 31 have a reset effect.

[0037] It should be noted that the jaws of the laparoscopic-assisted needle device are in a closed state in the initial state.

[0038] Please refer to Figure 3 , a first connecting block 6 is fixedly connected to the end of the transmission rod 5 far away from the second connecting block 8, and a pair of second connecting rods 43 are rotatably connected to the outer end of the first movable block 41. The end of the second connecting rod 43 far away from the first movable block 41 is rotatably connected to the first connecting block 6.

[0039] In this embodiment, when the second connecting block 8 and the transmission rod 5 at the outer end move, they can synchronously drive the first connecting block 6 to move, and the opening action of the first movable block 41 is realized by using the second connecting rod 43.

[0040] Please refer to Figure 3 , mutually engaging sawteeth are respectively engraved on the ends of a pair of second movable blocks 42 close to each other, which increases the friction force and improves the clamping effect.

[0041] Working principle: Medical staff can hold the grip ring 32 by hand, and penetrate through the abdominal wall through the first movable block 41 and the second movable block 42 in the closed state. When the medical staff pinches a pair of grip rings 32 and controls the pair of connecting handles 31 to move closer to each other, the second connecting block 8 and the transmission rod 5 at the outer end can be controlled to move by using a pair of first connecting rods 33, and the first connecting block 6 can be synchronously driven to move. The opening actions of the first movable block 41 and the second movable block 42 are realized by using the second connecting rod 43. When the grasping assembly 4 performs the opening action and the pair of second movable blocks 42 contact the tissue in the abdominal cavity, the second movable block 42 and the first movable block 41 will rotate relatively to provide avoidance and reduce the probability of damage to the tissue in the abdominal cavity. In addition, the spring 7 provided can make the connecting handle 31 have a reset effect, ensuring that the jaws of the device are in a closed state when not under force.

[0042] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
