Description

Technical Field

[0001] This invention relates to the field of cardiovascular surgery technology, and more specifically, to a surgical auxiliary device for cardiovascular interventional procedures. Background Technology

[0002] Cardiovascular interventional surgery, with its advantages of minimal invasiveness, rapid recovery, and definite therapeutic effects, has become a key method for treating cardiovascular diseases. Percutaneous vascular puncture is the crucial first step in establishing the surgical access, and its success directly affects the entire surgical process and patient safety. Currently, clinicians mainly rely on manual manipulation of the puncture needle.

[0003] According to the search, patent CN120284420A discloses a surgical assistance device for cardiovascular interventional procedures, including: a positioning structure comprising a concave frame and two first clamping structures, the two first clamping structures being respectively disposed at the bottom of two vertical beams of the concave frame; a positioning through hole vertically disposed on the crossbeam of the concave frame, a magnetic spherical rotating body rotatably disposed within the positioning through hole, the magnetic spherical rotating body having a vertical mounting through hole for external connection of a puncture needle; a positioning airbag disposed within the mounting through hole for positioning the puncture needle passing through the mounting through hole; a first positioning electromagnet disposed between the positioning through hole and the magnetic spherical rotating body for positioning the magnetic spherical rotating body after rotation; and a height adjustment component comprising a telescopic member and a second clamping structure, the telescopic member being vertically disposed on the upper side of the crossbeam, and the second clamping structure being disposed on the top of the telescopic member, greatly reducing the operational burden on medical personnel.

[0004] Regarding the aforementioned technologies, current existing technologies rely on the tactile sensation of the fingertips to perceive changes in resistance encountered when the needle tip penetrates tissue. In particular, when the needle tip breaks through the anterior wall of the blood vessel and enters the lumen, a brief "feeling of emptiness" is felt. At this moment, the advancement must be stopped immediately to prevent puncturing the posterior wall of the blood vessel. Secondly, the "feeling of emptiness" is a subtle tactile signal that is abstract and fleeting. Due to the small resistance, the overall change in force is difficult for doctors to accurately capture. Therefore, cases of excessively deep punctures due to delayed judgment or errors often occur, which can easily lead to complications such as hematoma. To address this, a surgical assistance device for cardiovascular interventional procedures is proposed. Summary of the Invention

[0010] Furthermore, the lever assembly includes a U-shaped block fixedly connected to the outer surface of the puncture tube, a central rod rotatably connected between the two sides of the inner wall of the U-shaped block, both ends of the central rod extending to the outside of the U-shaped block, and both ends of the central rod fixedly connected to swing arms, one end of the two swing arms being movably connected to push arms, and one end of the two push arms being movably connected to the outer surface of the two connecting rods respectively.

[0011] Furthermore, the lever assembly also includes a rotating column fixedly connected to the outer surface of the central rod. Two blocking blocks are fixedly connected to the outer surface of the rotating column, and two pointers are fixedly connected to the top of the U-shaped block. The two pointers contact the two blocking blocks respectively, and distance scale grooves are provided on both sides of the outer surface of the rotating column.

[0012] Furthermore, the lever arm assembly includes an inner hollow plate fixedly connected to the outer surface of the rotating column, an arm plate movably connected inside the inner hollow plate, a threaded rod rotatably connected to the inner wall of the inner hollow plate, the outer surface of the threaded rod being threadedly connected to the inner surface of the arm plate, and an adjusting paddle fixedly connected to the outer surface of the threaded rod, the outer surface of the adjusting paddle extending to the outside of the inner hollow plate.

[0013] Furthermore, the locking assembly includes a fixing frame fixedly connected to the outer surface of the U-shaped block, a ratchet groove is provided in the middle of the outer surface of the rotating column, a mounting seat is fixedly connected to the outer surface of the fixing frame, a ratchet rack is movably connected inside the mounting seat, one end of the ratchet rack passes through the fixing frame and is movably connected inside the ratchet groove, a pull rod is fixedly connected to the other end of the ratchet rack, the pull rod extends to the outside of the mounting seat, and a fixing spring is fixedly connected between the other end of the ratchet rack and one end of the inner wall of the mounting seat, the fixing spring being located outside the pull rod.

[0015] Furthermore, the main module also includes a universal bracket, which is provided with two mounting bolts, and the universal bracket is connected to the outer surface of the puncture tube through the two mounting bolts.

[0016] In summary, the present invention has the following beneficial technical effects:

[0017] (1) By setting up a pressure component, a pressure sensor, a locking component, a lever component, a lever arm component, a locking component and a control panel, the present invention can amplify the resistance encountered when the puncture needle advances through the lever principle and clearly transmit it to the operator's hand, which significantly enhances the doctor's sensitivity to the change of resistance and greatly improves the accuracy of recognizing the "feeling of loss"; at the same time, the pressure sensor monitors the resistance value in real time, and when a sudden decrease in resistance is detected, the puncture depth is instantly mechanically locked, which greatly reduces the risk of puncturing the back wall of the blood vessel due to judgment delay or operation error and improves the safety of the operation.

[0018] (2) The present invention ensures the stability and continuity of the puncture advance process by setting up ratchet groove, ratchet rack, fixed spring, magnetic block and pull rod, and avoids the puncture needle from accidentally retracting due to accidental touch or unstable hand. When it is necessary to withdraw the puncture needle, the lock can be released by manually pulling the pull rod, which is convenient to operate. The mechanical locking mechanism, as an independent safety measure, further enhances the operational reliability and safety of the entire device.

[0019] (3) The present invention achieves effective length adjustment of the lever arm by setting up an inner hollow plate, an arm plate, a threaded rod and an adjustment lever. This allows doctors to adjust the lever magnification ratio and operating feel according to their operating habits. While ensuring sufficient mechanical gain to amplify the feel, it avoids excessive sensitivity or loss of control due to excessive magnification, which significantly improves the adaptability and operating experience of the device.

[0020] (4) The present invention provides intuitive and real-time visual feedback on the depth of needle advance through the setting of distance scale groove, pointer and blocking block, which helps doctors to more accurately judge the puncture process and needle tip position, and can be used as a physical safety limit indication of puncture depth.

[0037] The following is in conjunction with the appendix Figures 1-10 The present invention will be described in further detail below.

[0038] Please see Figures 1-10A surgical auxiliary device for cardiovascular interventional procedures includes a main module 100 and a puncture module 200. The main module 100 includes a puncture cylinder 110, inside which a puncture needle 120 is disposed. Multiple ball bearings 130 are movably connected inside the puncture cylinder 110, arranged in a ring at equal intervals, with each ball bearing 130 close to one end of the puncture cylinder 110. An anti-slip groove 140 is formed on the outer surface of the puncture needle 120. The puncture module 200 includes two sliding grooves 210, both formed on the outer surface of the puncture cylinder 110, which are slidably connected. A pressure assembly 220 is connected to the outer surface of the puncture needle 120. A pressure sensor 230 is provided on the pressure assembly 220. A control panel 280 and a locking assembly 240 are installed on the outer surface of the puncture cylinder 110. The control panel 280 is electrically connected to the pressure sensor 230 and the locking assembly 240. The locking assembly 240 is adapted to the outer surface of the puncture needle 120. A lever assembly 250 is provided on the outer surface of the puncture cylinder 110. The lever assembly 250 is connected to the pressure assembly 220. A lever arm assembly 260 and a locking assembly 270 are provided on the outer surface of the lever assembly 250.

[0039] During use, the puncture needle 120 is aligned with the puncture site. The operator then activates the lever assembly 260, which drives the lever assembly 250. The lever assembly 250 pushes the pressure assembly 220, which in turn pushes the puncture needle 120, bringing it into contact with the puncture site. The pressure assembly 220 then slightly contracts, and the pressure sensor 230 displays the pressure reading on the control panel 280. After the pressure assembly 220 fully contracts, the lever assembly 260 continues to push, allowing the puncture needle 120 to penetrate the blood vessel. The pressure assembly 220 remains contracted. The lever assembly 260 and lever assembly 250 utilize the lever principle to push the puncture needle 120, amplifying the resistance during operation. This makes the "feeling of loss of resistance" more pronounced for the operator when the puncture needle 120 enters the blood vessel. Simultaneously, the reduced resistance will release the pressure component 220, causing a decrease in the pressure of the pressure sensor 230. When the pressure of the pressure sensor 230 decreases, the control panel 280 drives the locking component 240 to open. The locking component 240 will then contact the puncture needle 120, thereby fixing the position of the puncture needle 120 and maintaining it to prevent over-puncture. During the process of the lever component 250 pushing the pressure component 220, the locking component 270 achieves one-way locking of the lever arm component 260, thereby preventing accidental retraction of the puncture needle 120 before it enters the blood vessel, ensuring the normal progress of the puncture operation. The length of the lever arm component 260 can be adjusted, allowing for easy adjustment of the lever amplification force as needed, thus improving the effectiveness of the device.

[0040] The pressure assembly 220 includes a small inner hollow ring 222 and a large inner hollow ring 223. Two sliding blocks 221 are slidably connected inside each of the two sliding grooves 210. The small inner hollow ring 222 and the large inner hollow ring 223 are respectively fixedly connected between the two sliding blocks 221. A threaded ring 224 is fixedly connected to one side of the small inner hollow ring 222. A threaded block 225 is fixedly connected to the outer surface of the puncture needle 120, and the threaded block 225 is threadedly connected to the inside of the threaded ring 224. Connecting rods 226 are fixedly connected to the outer surfaces of both sliding blocks 221. The pressure assembly 220 also includes a resistance spring 227 fixedly connected to one side of the large inner hollow ring 223. A pressure sensor 230 is fixedly connected to one side of the small inner hollow ring 222 and is fixedly connected to the resistance spring 227. The locking assembly 240 includes two electric push rods 241 fixedly connected to the outer surface of the puncture cylinder 110. The output shafts of both electric push rods 241 extend into the interior of the puncture cylinder 110. One end of each electric actuator 241 is fixedly connected to a locking block 242. The outer surface of the locking block 242 is adapted to the outer surface of the puncture needle 120. The lever assembly 250 includes a U-shaped block 251 fixedly connected to the outer surface of the puncture cylinder 110. A central rod 252 is rotatably connected between the two sides of the inner wall of the U-shaped block 251. Both ends of the central rod 252 extend to the outside of the U-shaped block 251. Both ends of the central rod 252 are fixedly connected to swing arms 254. One end of each swing arm 254 is movably connected to a push arm 255. One end of each push arm 255 is movably connected to the outer surface of two connecting rods 226. The lever assembly 250 also includes a rotating column 253 fixedly connected to the outer surface of the central rod 252. Two blocking blocks 257 are fixedly connected to the outer surface of the rotating column 253. Two pointers 256 are fixedly connected to the top of the U-shaped block 251. The two pointers 256 contact the two blocking blocks 257 respectively. Distance scale grooves are provided on both sides of the outer surface of the rotating column 253.

[0041] The drive arm assembly 260 drives the rotating column 253 to rotate. During the rotation of the rotating column 253, it drives the swing arm 254 through the center rod 252. The swing arm 254 pushes the push arm 255 during its swing, which in turn pushes the connecting rod 226. The connecting rod 226 drives the large inner hollow ring 223. The large inner hollow ring 223 pushes the pressure sensor 230 and the small inner hollow ring 222 through the resistance spring 227, causing the threaded ring 224 to push the threaded block 225 and the puncture needle 120. The puncture needle 120 will then contact the puncture site. Afterward, the resistance spring 227 slightly contracts, and the pressure sensor 230 will be under pressure, which will be displayed on the control panel 280. After the resistance spring 227 is fully contracted, the arm plate 262 continues to push downward, allowing the puncture to proceed. When the needle 120 is inserted, the resistance spring 227 remains contracted. The lever assembly 260 and the lever assembly 250 use the lever principle to push the puncture needle 120, amplifying the resistance during operation. This makes the operator's perception of the "feeling of loss" more obvious when the puncture needle 120 enters the blood vessel. At the same time, when the "feeling of loss" occurs, the resistance decreases, which will release the resistance spring 227. The puncture needle 120 advances slightly, which reduces the pressure of the pressure sensor 230. When the pressure of the pressure sensor 230 decreases, the control panel 280 drives the two electric push rods 241 to open. The two electric push rods 241 will drive the two locking blocks 242 to contact the anti-slip groove 140 on the outer surface of the puncture needle 120, thereby fixing the position of the puncture needle 120 and preventing over-puncture.

[0042] The lever arm assembly 260 includes an inner hollow plate 261 fixedly connected to the outer surface of the rotating column 253. An arm plate 262 is movably connected inside the inner hollow plate 261. A threaded rod 263 is rotatably connected to the inner wall of the inner hollow plate 261. The outer surface of the threaded rod 263 is threadedly connected to the inside of the arm plate 262. An adjusting paddle 264 is fixedly connected to the outer surface of the threaded rod 263. The outer surface of the adjusting paddle 264 extends to the outside of the inner hollow plate 261.

[0043] Rotating the adjustment lever 264 can drive the threaded rod 263 to rotate, and the threaded rod 263 will cause the arm plate 262 to extend and retract inside the inner hollow plate 261, thereby allowing the length of the arm plate 262 to be adjusted.

[0044] The locking assembly 270 includes a fixed frame 271 fixedly connected to the outer surface of the U-shaped block 251. A ratchet groove 272 is provided in the middle of the outer surface of the rotating column 253. A mounting seat 273 is fixedly connected to the outer surface of the fixed frame 271. A ratchet rack 274 is movably connected inside the mounting seat 273. One end of the ratchet rack 274 passes through the fixed frame 271 and is movably connected inside the ratchet groove 272. A pull rod 277 is fixedly connected to the other end of the ratchet rack 274. The pull rod 277 extends to the outside of the mounting seat 273. A fixing spring 275 is fixedly connected between the other end of the ratchet rack 274 and one end of the inner wall of the mounting seat 273. The fixing spring 275 is located outside the pull rod 277. The locking assembly 270 also includes four magnetic blocks 276. The four magnetic blocks 276 are respectively fixedly connected to the other end of the ratchet rack 274 and one end of the inner wall of the mounting seat 273.

[0045] During the rotation of the central rod 252, the ratchet 274 will move on the outer surface of the ratchet groove 272. The ratchet 274 reciprocates towards the interior of the mounting seat 273, pressing the fixing spring 275. The ratchet 274 and the ratchet groove 272 achieve one-way locking of the lever arm assembly 260, thereby preventing accidental retraction of the puncture needle 120 when it has not entered the blood vessel, ensuring the normal progress of the puncture operation and improving overall safety. When it is necessary to remove the puncture needle 120, the operator pulls the lever 277 backward. The lever 277 will drive the ratchet 274 to retract from the ratchet groove 272. At this time, the four magnetic blocks 276 are attracted in pairs, thus keeping the ratchet 274 in a disengaged state.

[0046] The main module 100 also includes a universal bracket 150, which has two mounting bolts 160. The universal bracket 150 is connected to the outer surface of the puncture tube 110 through the two mounting bolts 160.

[0047] The universal bracket 150 allows the puncture needle 120 to be easily punctured at different angles. In actual use, the universal bracket 150 can be separated from the puncture cylinder 110 by removing the mounting bolt 160, so that the puncture cylinder 110 can be used by hand.

[0048] The implementation principle of this invention is as follows: During use, the universal bracket 150 is fixed to the side of the bed. Then, the universal bracket 150 is adjusted to fix the puncture cylinder 110 at a specified angle. The puncture needle 120 is aligned with the puncture site. Then, the operator moves the arm plate 262, which drives the rotating column 253 to rotate. During the rotation of the rotating column 253, it drives the swing arm 254 through the central rod 252. During the swing, the swing arm 254 pushes the push arm 255, which in turn pushes the connecting rod 226. The connecting rod 226 drives the large inner hollow ring 223. The large inner hollow ring 223 pushes the pressure sensor 230 and the small inner hollow ring 222 through the resistance spring 227, so that the threaded ring 224 pushes the threaded block 225 and the puncture needle. 120. The puncture needle 120 will contact the puncture site. Then, the resistance spring 227 slightly contracts, and the pressure sensor 230 will be under pressure, which will be displayed on the control panel 280. After the resistance spring 227 is fully contracted, the arm plate 262 continues to push downwards, allowing the puncture needle 120 to puncture. The resistance spring 227 remains contracted. The lever arm assembly 260 and the lever assembly 250 use the lever principle to push the puncture needle 120, amplifying the resistance during operation. This makes the operator's perception of the "feeling of loss" more pronounced when the puncture needle 120 enters the blood vessel. Simultaneously, when the "feeling of loss" occurs, the reduced resistance will release the resistance spring 227, allowing the puncture needle 120 to advance slightly, reducing the pressure on the pressure sensor 230. When the pressure decreases, the control panel 280 drives two electric actuators 241 to open. These actuators 241 then drive two locking blocks 242 to contact the anti-slip groove 140 on the outer surface of the puncture needle 120, thus fixing the position of the puncture needle 120 and preventing over-puncture. During puncture, the pointer 256 will point to the distance scale groove, directly displaying the puncture depth for easy monitoring during and after the procedure. As the center rod 252 rotates, the ratchet rack 274 moves on the outer surface of the ratchet groove 272. The ratchet rack 274 reciprocates towards the mounting seat 273, pressing the fixing spring 275. This unidirectional locking of the lever arm assembly 260 is achieved through the ratchet rack 274 and the ratchet groove 272, thus securing the puncture needle 120. Before the needle 120 enters a blood vessel, to prevent accidental retraction and ensure the smooth progress of the puncture procedure, thus improving overall safety, the operator pulls the lever 277 backward when the needle 120 needs to be removed. The lever 277 will cause the ratchet rack 274 to disengage from the ratchet groove 272. At this time, the four magnetic blocks 276 will attract each other in pairs, keeping the ratchet rack 274 in a disengaged state. Then, the electric push rod 241 controlled by the control panel 280 will cause the locking block 242 to separate from the needle 120. Pushing the two sliding blocks 221 connected to the small inner hollow ring 222 will pull out the needle 120. Rotating the adjustment lever 264 will drive the threaded rod 263 to rotate, which will cause the arm plate 262 to extend and retract inside the inner hollow plate 261.This allows for adjustment of the length of the arm plate 262, facilitating the adjustment of the lever amplification force as needed and improving the device's effectiveness. Rotating the puncture needle 120 causes the threaded block 225 to rotate and separate inside the threaded ring 224, thus separating the puncture needle 120 from the small inner hollow ring 222. Pulling the puncture needle 120 outwards allows for disassembly.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
