[0002] In the clinical diagnosis and treatment of hepatobiliary, pancreatic and splenic diseases, puncture sampling is an important means. For the diagnosis of malignant tumors such as liver cancer, cholangiocarcinoma, pancreatic cancer, and the pathological analysis of some chronic liver diseases, pancreatitis and other diseases, tissue samples need to be obtained by puncture for pathological examination; in addition, during the treatment of some diseases, such as the drainage of liver abscesses and the sclerotherapy of liver cysts, puncture techniques are also widely used; the development of imaging techniques such as ultrasound and CT provides more accurate guidance for puncture sampling; under the guidance of ultrasound or CT, doctors can more accurately locate the target lesions, improving the success rate and safety of puncture; this enables the minimally painful clinical puncture sampling device for hepatobiliary, pancreatic and splenic diseases to operate under more precise guidance, reducing damage to surrounding tissues.

[0003] In the prior art, traditional puncture devices have certain limitations in angle adjustment and are difficult to achieve precise adjustment in the horizontal and vertical directions, resulting in the puncture needle being unable to accurately reach the target position, increasing the difficulty and risk of puncture; moreover, during the puncture process, controlling the puncture depth is crucial for avoiding damage to surrounding tissues and blood vessels. However, existing puncture devices often lack an effective depth control mechanism, easily leading to over-puncturing or under-puncturing, affecting the success rate and safety of puncture.

[0004] Therefore, in view of the above problems in the prior art, the present solution proposes a minimally painful clinical puncture sampling device for hepatobiliary, pancreatic and splenic diseases. Summary of the Invention

[0006] To achieve the above technical effects, the present invention is realized through the following technical solutions: A minimally painful clinical puncture sampling device for hepatobiliary, pancreatic and splenic diseases, comprising: a support base, a connecting square, and a puncture frame.

[0007] The upper end of the support base is provided with a connecting square; the upper end of the connecting square is slidably connected to the puncture frame.

[0038] The guide rails 9 are arranged up and down, and guide grooves 34 are symmetrically arranged on both sides of the upper guide rail 9 and slidably connected to the sliders 38; a universal ball 37 is arranged at the upper end of the slider 38 and movably connected to the bottom of the depth cylinder 30;

[0039] A limiting post 29 is arranged at the place where the guide rail 9 is rotatably connected to the outside of the puncture frame 8 and movably connected to the limiting block 16;

[0040] A distance-adjusting screw rod 2 is arranged in the middle of the support base 1 and threadedly connected to another support base 1, and the upper end is slidably connected to a connecting square 4; a distance-adjusting knob 3 is arranged at the rear end of the distance-adjusting screw rod 2; a spherical cavity 18 is opened inside the connecting square 4 and rotatably connected to a connecting ball 27, and slide bars 5 are respectively arranged at the four corners and slidably connected to the puncture frame 8; a hole is opened in the middle of the connecting ball 27, and connecting sleeves 28 are arranged on both sides;

[0041] Sliding plates 36 are respectively arranged on both sides of the bottom of the connecting square 4 and slidably connected to the two support bases 1;

[0042] Expansion rods 6 are respectively arranged in the middle of the four sides of the connecting square 4; a sliding sleeve 7 is arranged at the upper end of the expansion rod 6 and fixedly connected to the puncture frame 8; a puncture spring 17 is arranged at the bottom of the sliding sleeve 7 and fixedly connected to the expansion rod 6;

[0043] The upper end of the guide groove 34 is slidably connected to the depth cylinder 30; depth grooves 32 are symmetrically opened on both sides of the depth cylinder 30, and a fixed ring 26 is slidably connected inside; a plurality of card slots 31 are arranged in an array on one side of the depth groove 32, and a scale 33 is arranged on the other side;

[0044] Clamping rods 25 are symmetrically arranged on both sides of the fixed ring 26 and slidably connected to the depth groove 32, and a clamping sleeve 19 is fixedly connected to the lower end; a handle 24 is arranged outside the clamping rod 25; clamping plates 20 are arranged in an array inside the clamping sleeve 19, and a clamping inner screw rod is arranged at the upper end and connected to an extrusion external thread 22; a locking knob 23 is arranged at the upper end of the extrusion external thread 22;

[0045] The upper end cross section of the clamping plate 20 is set as a right triangle;

[0046] In this embodiment, when the device is in use, the support base 1 is fixed at an appropriate position. The distance between the two support bases 1 is adjusted by the distance adjustment screw 2 and the distance adjustment knob 3 to adapt to different patient body types and puncture requirements. According to the target position determined under ultrasound or CT guidance, the angle of the puncture needle 35 is controlled by adjusting the angle of the guide rail 9. The puncture needle 35 is clamped within the clamping plate 20. At this time, by controlling the position of the clamping rod 25 within the depth cylinder 30, the puncture depth of the puncture needle 35 is accurately controlled. The scale 33 provides a depth reference to ensure that the puncture needle 35 reaches the target position without being too deep or too shallow. After the adjustment is completed, by pressing the top of the puncture needle 35, the puncture frame 8 is driven to slide downward along the slide bar 5, and the telescopic rod 6 is compressed and retracted into the sliding sleeve 7, compressing the puncture spring 17. After the puncture sampling is completed, the puncture frame 8 is bounced back upward by the elastic reset action of the puncture spring 17;

[0047] In this embodiment, when adjusting the angle of the puncture needle 35, by pulling the pull ring 11, the limit ring 12 is driven to slide outwards, thereby driving the slide bar 14 to slide, stretching the limit spring 15. At this time, the limit block 16 on the limit ring 12 disengages from the limit post 29, and thus the guide rail 9 can be rotated. After the adjustment is completed, the pull ring 11 is released, and under the elastic reset action of the limit spring 15, the limit ring 12 retracts, so that the limit post 29 is reinserted into the gap of the limit block 16 to lock the device;

[0048] In this embodiment, the bottom of the support base 1 can fix the device at the opening of the patient by means of clamping fixation, vacuum adsorption or strap fixation. The above technologies belong to conventional existing technologies, so they will not be elaborated in this solution;

[0049] In this embodiment, through the cooperation of the guide rail 9 and the rotating shaft 10, the angle of the puncture needle 35 in the horizontal and vertical directions can be accurately adjusted to ensure that the puncture needle 35 accurately reaches the target lesion, making the puncture process smoother and reducing the risk of damage to surrounding normal tissues.

[0061] In this embodiment, when fixing the puncture needle 35, the puncture needle 35 is passed through the chute of the guide rail 9 and placed between the clamping plates 20 of the clamping sleeve 19. By rotating the locking knob 23, the extrusion external thread 22 is driven to move downward, thereby squeezing the clamping plates 20 to tightly clamp the puncture needle 35. By controlling the position of the clamping rod 25 in the depth groove 32, the penetration depth of the puncture needle 35 can be accurately adjusted. The scale 33 provides a depth reference to ensure that the puncture needle 35 reaches the target position without being too deep or too shallow;

[0062] When the puncture needle 35 is clamped by the clamping plates 20 and adjusted to the appropriate depth, the puncture needle 35 is fixed in the corresponding position through the cooperation of the clamping rod 25 and the card slot 31 to ensure that it will not shift during the puncture process;
