Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an interventional treatment puncture assisting device. Background Art

[0002] Interventional cardiology devices are an important tool for treating cardiovascular diseases. They intervene in the human body in a minimally invasive way to diagnose and treat the heart and its related blood vessels. Cardiac interventional therapy is a new technology for diagnosing and treating cardiovascular diseases. It does not require thoracotomy. Under the guidance of imaging methods, the catheter is sent to the lesion site by puncturing the surface blood vessels with the help of certain instruments, and the heart disease is diagnosed and treated through specific cardiac catheter operation techniques.

[0003] During the interventional puncture process, the doctor needs to keep his hands stable and avoid shaking or sudden force to prevent the guidewire from deviating from the predetermined path or damaging the blood vessel. The angle and force of the puncture need to be precisely controlled to ensure that the guidewire can enter the blood vessel smoothly and to avoid excessive force that may cause blood vessel damage. However, existing interventional treatment devices usually require the performing doctor to send the guidewire into the patient's body through "sliding", "drilling", "piercing" and other techniques. The speed needs to be controlled by the doctor, which places extremely high demands on the doctor performing the operation. If the guidewire enters the wrong blood vessel fork and cannot be withdrawn in time, it may cause greater surgical risks. For this reason, we propose an interventional treatment puncture auxiliary device. Summary of the invention

[0037] See also Figures 1 to 8 ,The present invention provides a technical solution: an interventional treatment puncture auxiliary device, comprising: a pad 001;

[0038] Also includes:

[0039] Support plates 002, two support plates 002 are provided, and the two support plates 002 are symmetrically arranged about the central axis of the pad 001, and the support plates 002 can support the parts of the upper half of the pad 001;

[0040] A fixing plate 003, wherein two fixing plates 003 are provided, and the two fixing plates 003 are arranged inside the two supporting plates 002;

[0041] Guide wheels 004, which are provided in two groups. The two groups of guide wheels 004 are provided on the inner side of the fixing plate 003, and are used to guide the guide wire from the outside to the radial artery at the patient's wrist;

[0042] Adjustment component 005, two adjustment components 005 are provided, and the two adjustment components 005 are respectively provided on the outside of the two guide wheels 004, and are used to adjust the adjustment state of the two guide wheels 004 according to the patient's state. The adjustment component 005 includes a working gear 501, and two working gears 501 are provided. The side of the upper working gear 501 is meshed and connected with the first connecting gear 502, and the side of the lower working gear 501 is meshed and connected with the second connecting gear 503. The first connecting gear 502 is meshed and connected with the second connecting gear 503. The other side of the upper working gear 501 is meshed and connected with two driving gears 504. The bottom end of the rear driving gear 504 is installed with a driving motor 505, and the driving gear 504 is rotatably connected with the fixed plate 003.

[0043] Among them, the performing doctor finds the radial artery puncture position on the wrist, uses the puncture needle to perform puncture, and after the puncture is successful, inserts the puncture guide wire along the puncture needle and inserts the sheath to establish a channel for the subsequent entry of the guide wire and catheter, and then sends the guide wire into the two sets of guide wheels 004. The two sets of guide wheels 004 are distributed in the fixed plate 003, one in front and one in the back. The opening of the front set of guide wheels 004 is slightly opened, and the guide wire can smoothly enter it. The guide wire is guided so that the guide wire can be stretched, and the opening of the rear set of guide wheels 004 is tightened. The performing doctor inserts the guide wire into the opening and sends the guide wire into the patient's body through the sheath. The guide wheel 004 can stably and evenly transport the guide wire through the adjustment component 005;

[0044] Among them, when the performing doctor observes through the image that the guide wire enters the wrong branch blood vessel, the performing doctor can start the servo motor 360, and the servo motor 360 drives the toggle plate 350 to rotate in the opposite direction, so that a group of guide wheels 004 on the rear side open slightly, and a group of guide wheels 004 on the front side tighten, and the pressure sensor 560 that senses the pressure starts the corresponding drive motor 505, so that the guide wheel 004 on the rear side stops rotating, and the guide wheel 004 on the front side quickly pulls out the guide wire, so as to quickly pull out the guide wire that has entered the fork, so that the guide wire enters the correct route.

[0045] An annular rail 210 is fixedly connected between the two support plates 002, and a rotating ring gear 220 is rotatably connected inside the annular rail 210. Both sides of the inner wall of the rotating ring gear 220 are fixedly connected to the two fixed plates 003. The front side of the rotating ring gear 220 is meshingly connected with an adjusting gear 230. The number of teeth on the rotating ring gear 220 is 12 times the number of teeth on the adjusting gear 230, and a rotating component 006 is provided at the top of the adjusting gear 230.

[0046] Among them, when the doctor operates the adjustment gear 230 for one circle, it can drive the ring gear 220 to rotate thirty degrees, thereby rotating the ring gear 220 to drive the two sets of guide wheels 004 and the guide wires therein to rotate synchronously by thirty degrees. The doctor can operate the adjustment gear 230 to achieve a subtle rotation of the guide wire, so that the guide wire can smoothly pass through the blood vessel bifurcation and the lesion area with tricky angles.

[0047] Each group of guide wheels 004 is provided with two, and the two guide wheels 004 are arranged opposite to each other. Both ends of the guide wheels 004 are fixedly connected with fixed tubes 410, and the outer walls of the fixed tubes 410 are fixedly connected with collars 420. The interior of each fixed tube 410 is slidably connected with a limiting roller 430, and the two limiting rollers 430 are respectively fixedly connected with two working gears 501. The limiting rollers 430 are rotatably connected with the fixed plate 003. One of the fixed tubes 410 is rotatably connected with a first limiting plate 440 through a collar 420, and the interior of the first limiting plate 440 is slidably connected with a second limiting plate 450, and the second limiting plate 450 is rotatably connected with the other fixed tube 410 through the collar 420.

[0048] The top of the first limiting plate 440 is fixedly connected to a connecting frame 441, the top of the connecting frame 441 is fixedly connected to a tooth plate 442, the upper part of the tooth plate 442 is meshingly connected to a fan-shaped shift plate 443, the top of the fan-shaped shift plate 443 is fixedly connected to a transmission roller 444, the transmission roller 444 is penetrated by a fixing frame 445, the fixing frame 445 is fixedly connected to the fixing plate 003, the front end of the fixing frame 445 is penetrated by a positioning screw 446, and the positioning screw 446 is tightly connected to the transmission roller 444.

[0049] Among them, the staff can rotate the transmission roller 444 so that the transmission roller 444 drives the two fan-shaped shift plates 443 to drive the tooth plate 442 to move left and right. When the tooth plate 442 moves, the connecting frame 441 carries the fixed tube 410 to move synchronously through the ring 420. Since the first limit plate 440 is slidably connected with the second limit plate 450, when one of the fixed tubes 410 moves left and right in the limit roller 430, the lower fixed tube 410 will move simultaneously in the mutual cooperation of the first limit plate 440 and the second limit plate 450, thereby ensuring that a group of two guide wheels 004 will move synchronously. After adjusting the position of the guide wheel 004, the positioning screw 446 can be passed through the fixing frame 445 and tightly pressed against the transmission roller 444 to fix the transmission roller 444. The arrangement is convenient for pushing the two groups of guide wheels 004 to the top of the radial artery at the wrist according to the thickness range of the patient's wrist, avoiding bending of the guide wire and making it difficult to enter the puncture position.

[0050] The first connecting rod 510 is rotatably connected between the upper working gear 501 and the two driving gears 504, the second connecting rod 520 is rotatably connected to the outer sides of the upper working gear 501 and the first connecting gear 502 and the second connecting gear 503, and the third connecting rod 530 is rotatably connected to the outer sides of the lower working gear 501 and the second connecting gear 503.

[0051] The rear end of the lower working gear 501 is movably connected to a slider 540 , and a slide groove 550 is provided on the outer wall of the fixed plate 003 . The inner dimension of the slide groove 550 matches the outer dimension of the slider 540 , and a pressure sensor 560 is provided at the top of the slide groove 550 .

[0052] Among them, when the driving motor 505 drives the driving gear 504 to rotate, the driving gear 504 will transmit the working gear 501 on its side, and under the mutual cooperation of the first connecting gear 502 and the second connecting gear 503, the rotation direction of the other working gear 501 is adjusted, so that the two working gears 501 can rotate in opposite directions, driving the two guide wheels 004 to tighten the guide wire inside them and stably transport the guide wire.

[0053] At the same time, since the first connecting rod 510 connects the upper working gear 501 and the two driving gears 504, the second connecting rod 520 connects the upper working gear 501 with the first connecting gear 502 and the second connecting gear 503, and the third connecting rod 530 connects the lower working gear 501 with the second connecting gear 503, when the working gear 501 moves in the slide groove 550, it does not hinder the driving gear 504 from continuing to transmit power to the two working gears 501, thereby facilitating the adjustment of the position of the working gear 501 and the guide wheel 004.

[0054] The middle end of the fixed plate 003 is fixedly connected to a fixed seat 310, and the interior of the fixed seat 310 is rotatably connected to a T-shaped plate 320. Telescopic plates 330 penetrate the left and right sides of the T-shaped plate 320. The end of the telescopic plate 330 is movably connected to a connecting rod 340, and the top end of the connecting rod 340 is movably connected to the working gear 501.

[0055] The lower side of the fixed seat 310 is rotatably connected to a toggle plate 350, a servo motor 360 is installed at the end of the toggle plate 350, both ends of the toggle plate 350 are fixedly connected to toggle blocks 370, the top of the fixed seat 310 is rotatably connected to a telescopic tube 380, the inside of the telescopic tube 380 is slidably connected to a telescopic rod 390, a return spring 391 is provided on the outside of the telescopic rod 390, and the top of the telescopic rod 390 is rotatably connected to the T-shaped plate 320.

[0056] When the guide wire enters the wrong blood vessel, the doctor can start the servo motor 360, which drives the toggle plate 350. There are toggle blocks 370 on both sides of the top of the toggle plate 350. When the toggle block 370 drives the telescopic tube 380 to rotate to the other side, the reset spring 391 drives the telescopic rod 390 to expand rapidly inside the telescopic tube 380. During the expansion process, the T-shaped plate 320 movably connected to the telescopic rod 390 quickly rotates to the other side under the kinetic energy of the expansion, thereby The T-shaped plate 320 performs lever movement, and the telescopic plate 330 rotates together with the T-shaped plate 320. At the same time, the telescopic plate 330 drives the connecting rod 340 to rotate, and the connecting rod 340 props up the working gear 501 and the corresponding guide wheel 004, and drives the front guide wheel 004 to be tightened and the rear guide wheel 004 to be slightly opened through the adjustment component 005. The setting facilitates the rapid response of the two groups of guide wheels 004, and the guide wire is quickly pulled out one end of the distance in time to prevent the guide wire from entering the wrong blood vessel and causing a greater error.

[0057] Embodiment 2

[0058] like Figure 9-11In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the rotating assembly 006 includes a movable rod 601, which is fixedly connected to the adjusting gear 230. An outer wall of the movable rod 601 is provided with an inclined movable groove 602, and a vertical movable groove 603 is provided between the two ends of the inclined movable groove 602. The top depth of the inclined movable groove 602 is deeper than the depth of the vertical movable groove 603. A pressing rod 604 is slidably connected to the outer wall of the movable rod 601, and a movable shaft 605 is provided at the front end of the pressing rod 604. The movable shaft 605 is slidably connected to the inclined movable groove 602 and the vertical movable groove 603. A telescopic spring 606 is provided inside the movable shaft 605, and the movable shaft 605 is movably connected to the pressing rod 604 through the telescopic spring 606.

[0059] The outer wall of the pressing rod 604 is provided with a fixed shell 610, and the fixed shell 610 is fixedly connected to the annular rail 210. A limiting groove 620 is provided at the front end of the fixed shell 610. The internal sliding connection of the limiting groove 620 is a limiting block 630. The limiting block 630 is fixedly connected to the pressing rod 604. A plurality of buffer springs 640 are distributed in an internal annular array of the fixed shell 610, and the pressing rod 604 is movably connected to the fixed shell 610 through the buffer spring 640.

[0060] Among them, when the movable shaft 605 moves downward, the movable shaft 605 sinks into a deeper inclined movable groove 602 under the push of the telescopic spring 606, so that the movable shaft 605 can slide in the inclined movable groove 602 and move the movable rod 601. When the movable shaft 605 moves downward, the movable shaft 605 directly enters the vertical movable groove 603, which is convenient for the pressing rod 604 to return to its original position, which is conducive to the doctor's next use.

[0061] Among them, when the guide wire enters the bifurcated and narrow blood vessel, the performing doctor can press the pressing rod 604 downward, and the movable shaft 605 at the bottom end of the pressing rod 604 slides in the inclined movable groove 602, and then the movable rod 601 can rotate one circle along the inclined movable groove 602, and the movable rod 601 and the adjusting gear 230 rotate. When the adjusting gear 230 rotates one circle, the rotating gear ring 220 carries the two sets of guide wheels 004 to rotate thirty degrees. The performing doctor can adjust the angle of the guide wire according to the bifurcation of the blood vessel to prevent the situation where the guide wire is in the wrong direction and causes damage to the blood vessel.
