Description

Technical Field

[0001] This invention relates to the field of hepatobiliary surgical puncture device technology, and particularly to a hepatobiliary surgical puncture device that can be quickly positioned. Background Technology

[0002] Hepatobiliary puncture is a core procedure in minimally invasive diagnosis and treatment, including liver biopsy, biliary drainage, tumor ablation, and cyst aspiration. Its clinical success hinges on rapidly and accurately delivering the puncture needle to the target lesion while avoiding important structures such as blood vessels and bile ducts. Although current mainstream clinical positioning and puncture techniques are widely used, significant limitations remain in terms of positioning speed, real-time accuracy, interference resistance, and ease of operation, making it difficult to fully meet the precise and rapid puncture requirements for complex hepatobiliary lesions. To address this, patent CN113679453B discloses a multi-angle adjustable hepatobiliary surgical puncture device, comprising a body, a positioning hole, a positioning tube, and a puncture needle. An adsorption tube is embedded in the bottom wall of the body, penetrating the bottom wall to connect the interior of the body to the outside. A tympanic membrane is embedded in the side wall of the body, and a pull rod is embedded in the tympanic membrane, penetrating the inner and outer walls of the tympanic membrane. A pull plate is fixedly installed on the side wall of the pull rod away from the body. A fixing device is provided inside the body. In this invention, when the tympanic membrane deforms outward, the air inside the body is altered, reducing the internal pressure. This allows the body to be adsorbed onto the patient's skin via the adsorption tube. Inserting the puncture needle into the patient's body through the body at this point avoids positioning failures leading to incorrect puncture placement. The existing technical solutions mentioned above have the following drawbacks: when in use, it is impossible to quickly position the puncture needle auxiliary base according to the actual usage needs, resulting in problems such as excessive preparation time before puncture, reliance on physician experience for positioning accuracy, and poor consistency of operation. Summary of the Invention

[0003] The purpose of this invention is to provide a rapidly positioning hepatobiliary surgical puncture device to address the shortcomings of existing hepatobiliary surgical puncture devices that cannot rapidly position the puncture needle auxiliary base according to actual usage requirements.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hepatobiliary surgical puncture device that can be quickly positioned, including a puncture auxiliary base; A positioning mechanism is fixedly connected to the outer wall of the puncture auxiliary base, and a positioning buckle is fixedly installed on the outer wall of the puncture auxiliary base; The positioning mechanism includes a first sleeve fixedly installed on the outer wall of the puncture auxiliary base. An adjustment knob is movably connected to the outer wall of the first sleeve. A rotating shaft is fixedly connected to the outer wall of the adjustment knob. A second take-up roller is fixedly connected to the outer wall of the rotating shaft. A positioning strap is fixedly connected to the outer wall of the second take-up roller. A ratchet is fixedly connected to the outer wall of the rotating shaft. A support frame is fixedly connected to the outer wall of the first sleeve. A limit pin is movably connected inside the support frame. A spring return plate is fixedly connected to the outer wall of the limit pin.

[0005] Preferably, the second take-up roller forms a rotating structure with the first sleeve via a rotating shaft, and one end of the positioning strap is engaged with the positioning buckle via a buckle.

[0006] Preferably, the ratchet forms a rotating structure with the first sleeve via a rotating shaft, and the ratchet is movably connected to the limiting pin.

[0007] Preferably, the adjusting knob forms a rotating structure with the first sleeve via a rotating shaft, and the limiting pin forms a sliding structure with the support frame.

[0008] Preferably, a first take-up roller is fixedly connected to the outer wall of the rotating shaft, a traction rope is fixedly connected to the outer wall of the first take-up roller, a movable receiving rod is fixedly connected to one end of the traction rope, a piston is fixedly connected to one end of the movable receiving rod, a return spring is fixedly connected to one side of the piston, a second sleeve is movably connected to the outer wall of the piston, an air supply pipe is installed at the output end of the second sleeve, and a positioning suction cup is fixedly connected to the bottom of the puncture auxiliary base.

[0009] Preferably, the first take-up roller forms a rotating structure with the first sleeve via a rotating shaft, and one end of the traction rope is fixedly wound around the outer wall of the first take-up roller.

[0010] Preferably, the piston and the second sleeve form a sliding structure, and the return spring is sleeved and installed on the outer wall of the movable receiving rod.

[0011] Preferably, one end of the gas delivery tube is connected to the puncture auxiliary base, and the positioning suction cups are arranged in a ring around the central axis of the puncture auxiliary base.

[0012] Preferably, a puncture assist ball is movably connected inside the puncture assist base, a puncture needle is movably installed inside the puncture assist ball, a threaded groove is opened inside the puncture assist base, a positioning bolt is movably connected inside the threaded groove, and an anti-slip pad is fixedly connected to one end of the positioning bolt.

[0013] Preferably, the puncture assist ball and the puncture assist base form a rotating structure, the puncture assist base is a slotted design, the puncture assist base is threadedly connected to the positioning bolt through a threaded groove, and the anti-slip pad is adapted to the shape of the puncture assist ball.

[0014] The present invention provides a rapidly localized hepatobiliary surgical puncture device, the advantages of which are: By setting up a puncture auxiliary base and a positioning mechanism, the rotating shaft can be rotated by rotating the adjustment knob, which drives the second winding roller to rotate and wind the positioning strap, so that the positioning strap is tightened. This facilitates the quick installation and positioning of the puncture auxiliary base according to the patient's body shape, thereby making it easier to perform liver and gallbladder punctures more stably. Furthermore, with the combined action of the ratchet and the limit pin, the rotating shaft can self-lock after rotation, preventing the positioning strap from loosening unexpectedly after tightening, thus further improving the stability of the installation and positioning of the puncture auxiliary base. Furthermore, as the rotating shaft rotates, it drives the first take-up roller to rotate synchronously, which in turn drives the first take-up roller to pull the traction rope to move, causing it to slide along the second sleeve. This causes the piston to slide along the second sleeve and squeeze the reset spring, creating negative pressure inside the second sleeve. This causes multiple positioning suction cups to adhere to the patient's skin, further improving the stability of the puncture auxiliary base for quick positioning, reducing pre-puncture preparation time, and improving puncture efficiency. Furthermore, the piston can be reset by the action of the return spring, thereby allowing the puncture auxiliary base to be removed, improving the convenience of the puncture operation; The device is equipped with a puncture auxiliary base, a puncture auxiliary ball, a puncture needle, a positioning bolt, and an anti-slip pad. By pulling the puncture needle, the puncture auxiliary ball rotates along the puncture auxiliary base. When the puncture angle of the puncture needle is adjusted appropriately, rotating the positioning bolt moves the bolt, causing the anti-slip pad to press against the outer wall of the puncture auxiliary ball. This facilitates the adjustment and positioning of the puncture needle angle according to the actual needs of hepatobiliary puncture, thus improving the convenience of the puncture operation.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 The present invention provides a hepatobiliary surgical puncture device that can be quickly positioned, including a puncture auxiliary base 1.

[0019] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a positioning mechanism 2 is fixedly connected to the outer wall of the puncture auxiliary base 1, and a positioning buckle 3 is fixedly installed on the outer wall of the puncture auxiliary base 1. The positioning mechanism 2 includes a first sleeve 21 fixedly installed on the outer wall of the puncture auxiliary base 1. An adjusting knob 22 is movably connected to the outer wall of the first sleeve 21. A rotating shaft 23 is fixedly connected to the outer wall of the adjusting knob 22. A second take-up roller 24 is fixedly connected to the outer wall of the rotating shaft 23. A positioning strap 25 is fixedly connected to the outer wall of the second take-up roller 24. A ratchet 26 is fixedly connected to the outer wall of the rotating shaft 23. The outer wall of the first sleeve 21 is fixedly... A support frame 27 is fixedly connected, and a limit pin 28 is movably connected inside the support frame 27. A spring reset plate 29 is fixedly connected to the outer wall of the limit pin 28. The second take-up roller 24 forms a rotating structure with the first sleeve 21 through a rotating shaft 23. One end of the positioning strap 25 is engaged with the positioning buckle 3 through a buckle. The ratchet 26 forms a rotating structure with the first sleeve 21 through the rotating shaft 23. The ratchet 26 is movably connected with the limit pin 28. The adjusting knob 22 forms a rotating structure with the first sleeve 21 through the rotating shaft 23. The limit pin 28 and the support frame 27 form a sliding structure.

[0020] By passing the positioning strap 25 through the patient's body and engaging one end of the positioning strap 25 with the positioning buckle 3, rotating the adjustment knob 22 causes the rotating shaft 23 to rotate, which in turn rotates the second take-up roller 24 and winds the positioning strap 25, tightening it and fixing the puncture auxiliary base 1 onto the patient's skin. As the rotating shaft 23 rotates, it causes the ratchet 26 to rotate, squeezing the limiting pin 28 and causing the limiting pin 28 to slide along the support frame 27. At this time, the spring reset plate 29 is compressed, and under the action of the spring reset plate 29, the limiting pin 28 is reset and engaged in the next tooth groove of the ratchet 26, achieving self-locking of the tightened positioning strap 25. When it is necessary to loosen the positioning strap 25, simply pull the limiting pin 28 to slide along the support frame 27 and release the limiting of the ratchet 26.

[0021] Reference Figure 2 , Figure 4 and Figure 7 As shown, a first take-up roller 231 is fixedly connected to the outer wall of the rotating shaft 23. A traction rope 232 is fixedly connected to the outer wall of the first take-up roller 231. A movable receiving rod 233 is fixedly connected to one end of the traction rope 232. A piston 234 is fixedly connected to one end of the movable receiving rod 233. A return spring 235 is fixedly connected to one side of the piston 234. A second sleeve 236 is movably connected to the outer wall of the piston 234. An air supply pipe 237 is installed at the output end of the second sleeve 236. A positioning suction cup 238 is fixedly connected to the bottom of the puncture auxiliary base 1. The first take-up roller 231 passes through... The rotating shaft 23 and the first sleeve 21 form a rotating structure. One end of the traction rope 232 is fixedly wound around the outer wall of the first take-up roller 231. The piston 234 and the second sleeve 236 form a sliding structure. The return spring 235 is sleeved and installed on the outer wall of the movable receiving rod 233. One end of the air supply pipe 237 is connected to the puncture auxiliary base 1. The positioning suction cups 238 are arranged in a ring around the central axis of the puncture auxiliary base 1. An air supply channel is opened inside the puncture auxiliary base 1, and one end of the channel is connected to the air supply pipe 237; the other end is connected to the positioning suction cup 238.

[0022] As the rotating shaft 23 rotates, it drives the first take-up roller 231 to rotate synchronously, causing the traction rope 232 to be wound around the outer wall of the first take-up roller 231. This causes the first take-up roller 231 to pull the traction rope 232 to move, making it slide along the second sleeve 236. This causes the piston 234 to slide along the second sleeve 236 and squeeze the return spring 235, creating a negative pressure inside the second sleeve 236. This causes the air supply pipe 237 to draw air inward, causing the positioning suction cup 238 to be drawn out. This causes multiple positioning suction cups 238 to adhere to the patient's skin. When the rotating shaft 23 reverses, it causes the traction rope 232 to release the traction on the movable receiving rod 233. Under the action of the return spring 235, the piston 234 returns to its original position, causing the positioning suction cups 238 to release their adhesion to the patient's skin.

[0023] Reference Figure 3 , Figure 4 and Figure 8 As shown, a puncture auxiliary ball 4 is movably connected inside the puncture auxiliary base 1. The puncture auxiliary ball 4 has a slotted design, and a puncture needle 5 is movably installed inside the puncture auxiliary ball 4. A threaded groove 6 is opened inside the puncture auxiliary base 1, and a positioning bolt 7 is movably connected inside the threaded groove 6. An anti-slip pad 8 is fixedly connected to one end of the positioning bolt 7. The puncture auxiliary ball 4 and the puncture auxiliary base 1 form a rotating structure. The puncture auxiliary base 1 has a slotted design, and the puncture auxiliary base 1 is threadedly connected to the positioning bolt 7 through the threaded groove 6. The anti-slip pad 8 is adapted to the shape of the puncture auxiliary ball 4.

[0024] By pulling the puncture needle 5, the puncture auxiliary ball 4 is rotated along the puncture auxiliary base 1. When the puncture angle of the puncture needle 5 is adjusted appropriately, the positioning bolt 7 is rotated. Since the positioning bolt 7 is threadedly connected to the puncture auxiliary base 1 through the threaded groove 6, the positioning bolt 7 can be moved, causing the anti-slip pad 8 to press against the outer wall of the puncture auxiliary ball 4, so that the puncture auxiliary ball 4 after the angle is adjusted is limited.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
