[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] Example like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, an anesthetic puncture kit puncture auxiliary device is provided, including a lifting clamping mechanism 1, and the number of lifting clamping mechanisms 1 is two; The lifting clamping mechanism 1 includes a lifting seat 101, a base plate 102 is slidably connected inside the lifting seat 101, a lifting screw 103 is rotatably connected to the upper surface of the base plate 102 via a rotating shaft, the top end of the lifting screw 103 extends through to the top of the lifting seat 101, and a lifting plate 104 is threadedly connected to the outer wall of the lifting screw 103 and the inner side of the lifting seat 101. A bidirectional spiral rod 105 is rotatably connected to the inner side of the lifting seat 101 and below the base plate 102 via a rotating shaft. Two spiral sleeves 106 are spirally installed on the outer side wall of the bidirectional spiral rod 105. A rotating head 107 is rotatably connected to the upper surface of the spiral sleeve 106 via a rotating shaft. A traction rod 108 is rotatably connected to the outer side wall of the rotating head 107 via a rotating shaft. A rotating head 109 is rotatably connected to the top of the traction rod 108 via a rotating shaft. The top of the rotating head 109 is fixedly connected to the lower surface of the base plate 102. A limiting groove 110 is opened on the side of the lifting seat 101 away from the guide mechanism 2. A limiting block 111 is fixedly connected to the outer side wall of the spiral sleeve 106 and inside the limiting groove 110. Both ends of the bidirectional spiral rod 105 extend to the outside of the lifting seat 101 and are fixedly connected to connecting pieces 112. The bottom ends of the two front and rear opposite connecting pieces 112 are fixedly connected to a concave clamping seat 113. A clamping plate 114 is slidably connected to the inner side of the concave clamping seat 113. An adjusting bolt 115 is rotatably connected to the side of the clamping plate 114 away from the guide mechanism 2 via a rotating shaft. The end of the adjusting bolt 115 away from the clamping plate 114 extends to the outside of the concave clamping seat 113 and is threadedly connected to the concave clamping seat 113. Two limiting rods 116 are fixedly connected to the side of the clamping plate 114 near the adjusting bolt 115. The end of the limiting rod 116 away from the clamping plate 114 extends to the outside of the concave clamping seat 113 and is slidably connected to the concave clamping seat 113. The front surface of the lifting seat 101, starting from the outer side of the bidirectional spiral rod 105, has two mutually perpendicular positioning holes 117. A positioning rod 118 is provided in front of the connecting piece 112 on the front surface of the lifting seat 101. The rear end of the positioning rod 118 passes through the connecting piece 112 and is inserted into the positioning hole 117 located above the outer side of the bidirectional spiral rod 105. A pulling block 119 is fixedly connected to the front end of the positioning rod 118. A spring 120 is fixedly connected to the opposite side of the pulling block 119 and the connecting piece 112, and to the outer side of the positioning rod 118. In actual clinical surgical scenarios, the structure and gap shape of the edge of the operating table are diverse. The lifting clamping mechanism 1 of this device can flexibly adapt to different bed conditions. When there is a suitable vertical gap at the edge of the bed, the concave clamping seat 113 can be installed with the opening facing downward. Medical staff only need to smoothly clamp the concave clamping seat 113 from above the edge of the bed to the edge, and then hold the adjusting bolt 115 with their hands and slowly rotate it. Under the limiting action of the limiting rod 116, the clamping plate 114 will move smoothly along the fixed direction and gradually approach the edge of the bed. As the rotation continues, the clamping plate 114 and the concave clamping seat 113 work together to firmly clamp the edge of the bed. At this time, under the elastic tension of the second spring 120, the positioning rod 118 is inserted into the positioning hole 117 above the outer wall of the bidirectional spiral rod 105, forming a stable positioning structure, which is like adding a safety lock to the concave clamp 113, ensuring that it can withstand various external forces during the operation and maintain high stability in the state of opening downward, without shaking or displacement. When the edge structure of the bed is special and not suitable for vertical locking, and a horizontal locking method is required, the medical staff should first hold the pull block 119 with their hands and pull the positioning rod 118 out of the current positioning hole 117 with a little force. After releasing the positioning constraint, rotate the connecting piece 112. Since the connecting piece 112 is fixedly connected to the bidirectional spiral rod 105, the bidirectional spiral rod 105 will also rotate synchronously. During the rotation, under the limiting constraint of the limiting block 111 and the limiting groove 110, the two spiral sleeves 106 will move relative to each other along the bidirectional spiral rod 105. This movement is driven by the linkage of the rotating head 107, the rotating head 2 109 and the traction rod 108 to drive the base plate 102 to rise smoothly. When the concave clamping seat 113 rotates to the horizontal state, the openings of the two concave clamping seats 113 face each other, forming a stable horizontal clamping structure. At this point, the medical staff inserted the positioning rod 118 into another positioning hole 117 to complete the precise positioning of the lateral position.
[0018] This ingenious design allows the adjustment range of the lifting screw 103 to remain relatively stable after the concave clamp 113 rotates from the same vertical position below the lifting seat 101 to a mutually perpendicular state. Even with different engagement methods, medical personnel can easily and accurately adjust the puncture height, effectively avoiding the problem of the lifting screw 103's height adjustment range becoming smaller due to changes in the state of the concave clamp 113, greatly improving the device's versatility and ease of operation. The device can control the lifting plate 104 to rise or fall by holding the lifting screw 103, thereby controlling the height of the guide mechanism 2 and the piercing mechanism 3.
[0019] like Figure 7 and Figure 8 As shown, a guide mechanism 2 is provided between the two lifting and clamping mechanisms 1; The guide mechanism 2 includes an arc-shaped guide rail 201. The inner rear surface of the arc-shaped guide rail 201 has a through arc-shaped groove 202. A moving block 203 is slidably connected to the inner side of the arc-shaped guide rail 201. A fastening bolt 204 is threadedly connected to the inner rear of the moving block 203 and to the inner side of the arc-shaped groove 202. The two ends of the arc-shaped guide rail 201 are fixedly connected to the opposite sides of the two lifting plates 104 respectively. In actual anesthesia puncture operations, patients' body shapes, puncture sites, and surgical needs vary. Therefore, it is crucial to accurately adjust the puncture position. After the puncture needle body 4 is initially placed inside the puncture mechanism 3, medical staff can push the moving block 203 by hand to slide it along the inner side of the arc-shaped guide rail 201. The unique arc design of the arc-shaped guide rail 201 provides a multi-angle and flexible operating space for adjusting the puncture position, which can meet the puncture needs of different patients and surgical scenarios. After the medical staff adjusts the puncture site to a suitable angle and position according to the patient's specific condition, they need to operate the hand-held fastening bolt 204. By rotating the fastening bolt 204, it is gradually moved towards the inside of the moving block 203 until the fastening bolt 204 is tightly fitted with the arc-shaped guide rail 201. As the fastening bolt 204 is tightened, the friction between the two gradually increases, thereby achieving a firm lock on the position of the moving block 203. Once the moving block 203 is positioned, the positions of the puncture mechanism 3 and the puncture needle body 4 are also determined, ensuring that the puncture needle can accurately reach the predetermined puncture point.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, a puncture mechanism 3 is provided on the front surface of the guide mechanism 2; The puncture mechanism 3 includes a protective cylinder 301. A through-type lifting groove 302 is provided on the left side of the protective cylinder 301. A lead screw 303 is rotatably connected to the inner side of the lifting groove 302 via a rotating shaft. A gear 304 is fixedly connected to the lower side of the outer wall of the lead screw 303. A lifting sleeve 305 is threadedly connected to the upper side of the outer wall of the lead screw 303. A sleeve 306 is fixedly connected to the right side of the lifting sleeve 305 inside the protective cylinder 301. Two arc-shaped clamps 307 are provided on the inner side of the sleeve 306. Multiple springs 308 are fixedly connected between the arc-shaped clamps 307 and the sleeve 306. The inside of the lifting sleeve 305 is located on the left side of the protective cylinder 301 and is rotatably connected to two rotating rods 309 via a rotating shaft. The top of the rotating rods 309 is fixedly connected to a pressing plate 310. A shaft seat 311 is symmetrically fixedly connected to the lower left front of the lifting sleeve 305. Two rotating rods 312 are rotatably connected to the lower surface of the shaft seat 311 through a rotating shaft. A lower baffle 313 is fixedly connected to the bottom end of each of the two rotating rods 312. Gear 2 314 is meshed with the outer wall of gear 1 304. A micro motor 315 is provided below gear 2 314. The top of the output shaft of micro motor 315 is fixedly connected to the center of the lower surface of gear 2 314. The right side of micro motor 315 is fixedly connected to the left side of protective cylinder 301. The top end of the rotating rod 312 extends through to the top of the bearing 311 and is fixedly connected to the gear 316; A fixing plate 317 is fixedly connected to the upper left side of the protective cylinder 301, outside the two rotating rods 309. The upper surface of the fixing plate 317 is rotatably connected to a gear 318 via a rotating shaft. Gear 316 meshes with gear 318. A limiting strip 319 is integrally formed on the outer wall of the rotating rod 309 and inside the gear 318. The limiting strip 319 is slidably connected to gear 318. The front surface of the movable block 203 is fixedly connected to the rear surface of the protective cylinder 301; The puncture mechanism 3 has a puncture needle body 4 on its inner side; The puncture needle body 4 includes a needle tip 401, and a needle seat 402 is integrally formed at the top of the needle tip 401. An annular groove 403 is provided on the outer side wall of the needle seat 402. The needle tip 401 is engaged between two arc-shaped clamps 307, and the opposite sides of the two pressing clamps 310 are engaged with the inner side of the annular groove 403. During the surgical preparation stage, in order to ensure the safety and accuracy of the puncture process, medical staff need to perform pre-operation on the puncture mechanism 3. First, hold the two pressure plates 310 with both hands and slowly rotate them in opposite directions to separate the two pressure plates 310. Since gear four 318 is slidably installed on the outside of rotating rod one 309 through the limiting strip 319, as the two rotating rods one 309 rotate with the pressure plates 310 separating, they will drive the two gear four 318 to rotate synchronously in opposite directions. Through the meshing transmission of gear four 318 and gear three 316, the two rotating rods two 312 will rotate relative to each other, and finally cause the two lower baffles 313 to rotate relative to each other and fit together to form a closed structure, completely blocking the bottom of the protective cylinder 301. At this time, medical staff can carefully insert the needle tip 401 of the puncture needle body 4 between the two arc-shaped clamps 307. Under the elastic compression of multiple springs 308, the arc-shaped clamps 307 will tightly clamp the needle tip 401, achieving initial clamping and limiting. When the subsequent moving puncture mechanism 3 performs guiding operations along the guide mechanism 2, some vibration or external interference will inevitably occur in the surgical environment. At this time, the lower baffle 313 blocking the bottom of the protective cylinder 301 plays a key role. It can effectively prevent the needle tip 401 from falling off due to the arc-shaped clamps 307 not clamping firmly. This design not only provides good shielding and protection for the bottom of the needle tip 401, avoiding the problem of the needle tip 401 being exposed and easily scratching medical staff or patients in the prior art, but also provides double protection in terms of safety. Even if the switch of the micro motor 315 is accidentally touched during operation, the needle 401 cannot extend downwards because the bottom of the needle 401 is blocked by the lower baffle 313. At this time, the needle 401 is only subjected to the clamping force of the arc-shaped clamp 307 pushed by the spring 308. When the descent of the needle 401 is obstructed, the arc-shaped clamp 307 and the needle 401 will slide relative to each other, and the needle 401 will not be easily bent, thus effectively protecting the integrity of the puncture needle. When the formal puncture procedure begins, medical personnel need to rotate the two lower clamping plates 310 towards the center and merge them, so that they accurately engage with the annular groove 403 on the outside of the needle holder 402. During this process, through the precise cooperation and transmission between rotating rod 1 309, rotating rod 2 312, gear 3 316, and gear 4 318, the two lower baffles 313 will rotate and separate again, opening the bottom of the protective cylinder 301. At this time, medical personnel activate the micro motor 315. The output shaft drives gear 314 to rotate. Through the meshing transmission between gear 314 and gear 304, the lead screw 303 begins to rotate. As the lead screw 303 rotates, the lifting sleeve 305 descends smoothly along the inner side of the lifting groove 302, thereby driving the rotating rod 309 to descend as well. Since the lowering plate 310 is locked inside the annular groove 403, during the descent of the lifting sleeve 305, the lowering plate 310 drives the needle 401 to move downwards smoothly, ultimately completing the precise puncture. After the puncture is completed, to prevent the needle 401 from being accidentally pulled out due to accidental activation of the micro motor 315 switch during subsequent surgeries, medical personnel can control the two lowering plates 310 to separate again, restoring a safe protective state and providing reliable safety for the entire surgical process.
