[0032] In summary: the utility model discloses a laparoscopic puncture device. Abdominal wall hernia refers to an extraperitoneal hernia occurring in the abdominal wall, which is a type of extraperitoneal hernia. Abdominal wall hernia can only be cured through surgery, and surgical methods can be divided into open hernia and laparoscopic minimally invasive surgery. Laparoscopic minimally invasive surgery has small trauma and fast recovery, and requires a laparoscopic puncture device to cooperate with minimally invasive equipment. The laparoscopic puncture device is a surgical instrument that provides an instrument channel for minimally invasive surgery. It is a medical device used for puncture sampling or injection to achieve treatment; the puncture tube assembly 1 is provided with a puncture inner needle core 12. One end of the puncture needle is used to puncture the patient's abdomen. Usually during the puncture treatment, medical staff are required to hold the puncture device and maintain a posture to perform sampling or injection. Long-term hand-held work will cause discomfort to medical staff and is prone to puncture deviation. The puncture tube assembly 1 in the utility model is fixed with a puncture inner needle core 12. The assembly 2 is installed in a matching combination, and the outer ring body 21 is fixedly mounted at a position remaining outside the patient's body, and this position is close to the patient's outer skin. The medical staff aligns the puncture needle sheath 11 and the puncture inner needle core 12 with the patient's designated part for puncture. During this process, the medical staff can adjust the position and insertion depth of the puncture head by rotating or pushing and pulling the puncture tube assembly 1. When the puncture needle sheath 11 is adjusted to a suitable angle, the operator can use the fixing assembly 2 to fix it on the abdomen of the patient after the pneumoperitoneum is raised, and cover the hinged support plate 28 on one side of the puncture needle sheath 11. The puncture needle sheath 11 is fixed on the patient's skin by the medical patch 29 at the bottom thereof, thereby stabilizing the hinged support plate 28 and the puncture needle sheath 11. To further stabilize the hinged support plate 28 and the puncture needle sheath 11, the operator turns over the connecting plate 24 to fit the second magnet block 23 at one end of the connecting plate 24 with the first magnet sheet 22. The first magnet sheet 22 and the second magnet block 23 are magnetically fixedly connected. The fixing assembly 2 firmly supports the puncture tube assembly 1 and the patient. The subsequent whole process does not require medical staff to use both hands to hold and fix the puncture device for a long time; there is no need to use the puncture tube assembly 1 for a long time. The connecting plate 24 is flipped to separate the second magnet block 23 from the first magnet sheet 22 first, and then the hinged support plate 28 is flipped to separate the medical patch 29 from the patient's skin. The operator can then remove the puncture tube assembly 1 from the patient's abdomen, and the operator can frequently replace the medical patch 29 to maintain its firm adhesion. This arrangement uses the designed fixing assembly 2 to firmly support the puncture tube assembly 1, which is beneficial to prevent the displacement of the puncture device during treatment, and can also ensure the stability of the puncture needle, avoid continuous manual hand-held operation of the puncture tube assembly 1, and reduce the burden on medical staff;

[0033] The conventional laparoscopic puncture device only achieves treatment by installing a surgical tube at the rear end of the handle assembly 3 for sampling or injection of the puncture device. If the medical staff needs to sample and inject the patient's abdominal cavity at the same time, only one surgical tube cannot meet the treatment needs, which limits the scope of applicability of the device. The utility model makes a hole in the puncture needle sheath 11 near one end of the puncture needle head. In order to prepare for placing one more surgical tube into the puncture device, the through-hole groove 13 is interconnected with the puncture inner needle core 12, and one end of the newly added surgical tube 48 is arranged on the pipeline anti-dropping On one side of the assembly 4, the newly added surgical tube 48 is inserted through the pipeline connecting component 41 and the newly added surgical tube 48 is connected to the puncture inner needle core 12. At this time, the newly added surgical tube 48 is between the two groups of clamping plates 47. In order to prevent the newly added surgical tube 48 from falling off between the newly inserted and installed puncture tube assembly 1, the operator needs to reinforce the newly added surgical tube 48 and turn the knob 45. The knob 45 drives the forward and reverse screw rods 44 to rotate. The forward and reverse screw rods 44 drive the two groups of sliding plates 46 to move closer to each other. The two groups of sliding plates 46 drive the two groups of clamping plates 47 to move closer to each other until The two groups of clamping plates 47 are combined to limit and stabilize the outer periphery of the newly added surgical tube 48. The surgical tube section is limited and stabilized by the two groups of clamping plates 47, which can prevent the newly added surgical tube 48 from falling off and separating from the puncture tube assembly 1 during the treatment process. The outer end of the newly added surgical tube 48 can be connected to external equipment, and the through-hole groove 13 left in the patient's body is used for material passing. When tissue sampling or drug injection is required, the through-hole groove 13, the puncture inner needle core 12 and the newly added surgical tube 48 are used to complete the puncture needle sampling or injection work, so as to achieve the treatment effect; when the newly added surgical tube 48 is needed, When separated from the puncture tube assembly 1, the knob 45 can be rotated in the opposite direction, and the forward and reverse screw rods 44 are driven to rotate in the opposite direction, and the forward and reverse screw rods 44 drive the two groups of clamping plates 47 to move away from each other until the two groups of clamping plates 47 are completely away from the newly added surgical tube 48. The subsequent operator can pull the newly added surgical tube 48 out of the puncture tube assembly 1. Compared with the traditional puncture needle, this arrangement allows the puncture tube assembly 1 to be installed with two surgical tubes, thereby improving the therapeutic applicability of the puncture needle, and the clamping effect of the pipeline anti-detachment assembly 4 can prevent the pipeline and the puncture needle from falling off, thereby improving the therapeutic effect and practicality of the device.
