Description

Technical Field

[0001] The present invention relates to the technical field of interventional medical equipment, and in particular to a guidewire guiding device and medical intervention equipment. Background Art

[0002] In medical interventional technology, the core value of a guidewire, a thin, rigid and flexible metal wire made of nickel-titanium alloy, stainless steel and other materials, lies in providing "path guidance" and "support positioning" for interventional devices such as catheters and stents. This is because natural cavities such as human blood vessels, bile ducts, and ureters often have curved, narrow or branched structures. Directly pushing the device may fail to reach the target position due to directional deviation and excessive resistance, and may even cause tissue damage. The guidewire, however, can be the first to traverse complex paths due to its maneuverability (such as end shaping and torque transmission), and its diameter is usually much smaller than that of the catheter, so it can reach the lesion site (such as vascular stenosis, tumor blood supply vessels) before the catheter. After confirming the position through fluoroscopic images (such as DSA), the guidewire can be inserted into the lesion site. It can guide subsequent devices to avoid blindly touching normal tissues and reduce the risks of bleeding and perforation. At the same time, its physical properties (such as hardness, coating, and tip shape) can be customized according to the characteristics of the lesion to adapt to different treatment needs. The guidewire has a wide range of usage scenarios, covering cardiovascular intervention (such as PCI for coronary heart disease, electrophysiological examination of arrhythmias, stent treatment of peripheral vascular diseases, etc.), neurointervention (such as cerebral aneurysm embolization, acute ischemic stroke thrombectomy), non-vascular intervention (such as ERCP in gastroenterology, ureteroscopy in urology, local drug infusion in oncology) and other scenarios such as dialysis access establishment and congenital heart disease closure. It is a key instrument for "threading the needle" in interventional surgery.

[0003] Chinese patent publication number CN221932828U discloses a "guidewire guiding device and medical interventional equipment," comprising a guide plate disposed along the length of the guidewire, with the rear edge of the guide plate connected to the front end of the guidewire. The two surfaces of the guide plate are a first guide surface and a second guide surface. An adjustment assembly is used to control the guide plate to bend toward either the first or second guide surface. The pressure differential between the first and second guide surfaces causes the front end of the guidewire to bend. This curved portion of the guidewire allows the guidewire to pass from the main vessel into the branch vessel, thereby ensuring accurate and safe guidance of the guidewire.

[0004] Similarly, comparing the existing technology and the guidewire guidance device mentioned above, first, when medical personnel grasp a small guidewire and rotate it, due to its tiny diameter, it is difficult to evenly control the grip force of their fingers on the guidewire. Even a slight force may cause the guidewire to over-rotate, which may deviate from the preset path at best, or require retraction and adjustment at worst. Secondly, from the perspective of operational efficiency and reducing medical personnel fatigue, when traditionally pinching a guidewire and rotating it, to achieve the target turning point, medical personnel need to repeatedly fine-tune the finger force and rotation amplitude, often going through multiple "trial and correction" cycles to make the guidewire turn as expected. This not only prolongs the surgical operation time, but also requires medical personnel to maintain subtle hand movements for a long time, which can easily cause finger muscle tension and fingertip fatigue, thereby increasing the probability of operational errors. Furthermore, from the perspective of surgical safety and patient prognosis, when traditionally pinching a guidewire and rotating it, the contact area between the finger and the tail end of the guidewire is limited. During rotation, slight tremors or slippage of the hand can easily cause the guidewire tip to suddenly deviate. In complex lesions such as vascular stenosis and calcification, this sudden deviation may cause vascular endothelial scratches, increasing the risk of thrombosis or vascular perforation.

[0005] To this end, a guidewire guiding device and a medical intervention device are proposed. Summary of the Invention

[0006] The object of the present invention is to provide a guidewire guiding device and a medical intervention device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a guidewire guiding device and a medical interventional device, comprising a main blood vessel example, a hand grip rod, and a guidewire example. A precise rotation assembly is provided on the right side of the main blood vessel example, and the precise rotation assembly comprises a rotating cylinder, the internal rotation of the rotating cylinder is connected to the side wall of the hand grip rod, and a plurality of arc gears are fixedly connected to the inner side of the rotating cylinder. The plurality of arc gears are arranged in a circular array with the center of the rotating cylinder as a reference object. The number of the plurality of arc gears is set to seventy-two, and the degree formed between each adjacent arc gear and the center of the rotating cylinder is five degrees. Two notches are provided on the hand grip rod, and the internal rotation of each notch is connected to a rotating rod, and the outer side of each rotating rod is fixedly connected to a rotating arc block, and the interior of each notch is fixedly connected to a spring.

[0008] Furthermore, each of the rotating arc blocks is fixedly connected to the side of the spring away from the handle, the outer arc surface 1 of the rotating arc block is opposite to the outer arc surface 2 of each arc gear, and the rotating arc block is engaged with the gap between each two adjacent arc gears.

[0009] Furthermore, the side wall of the rotating cylinder is provided with an adapter guide assembly, and the adapter guide assembly includes a first circular ring, which is rotatably connected to the side wall of the rotating cylinder, and the side wall of the rotating cylinder is fixedly connected to a first connecting column, and the end of the first connecting column away from the rotating cylinder is rotatably connected to a rotating rectangular block 1, the outer side of the first circular ring is fixedly connected to a fixed rectangular block, and the side of the fixed rectangular block away from the rotating cylinder is rotatably connected to a rotating rectangular block 2, and the interior of the rotating rectangular block 1 is penetrated and rotatably connected to a threaded rod, and the end of the threaded rod close to the rotating rectangular block 1 is fixedly connected to a handle.

[0010] Furthermore, the adapter guide assembly also includes three rotating columns, each of which is rotatably connected to the side wall of the rotating cylinder, and a connecting rod is fixedly connected to the outer side of each rotating column. The first ring is fixedly connected to the side away from the rotating cylinder with a second ring, and the interior of the second ring is penetrated and rotatably connected with three second connecting columns, and each of the second connecting columns is fixedly connected to a rectangular sliding sleeve at one end close to the first ring, and each of the connecting rods is fixedly connected to a fixed round block at one end away from the rotating column, and the material of the fixed round block is set to rubber material.

[0011] Furthermore, the side of the main blood vessel example away from the rotating cylinder is provided with the auxiliary blood vessel example 1 and the auxiliary blood vessel example 2, and the end of the guide wire example away from the rotating cylinder is provided with a development marker inside.

[0012] Furthermore, the first connecting column is eccentrically arranged with the center of the rotating cylinder as a reference, and the outer side of the threaded rod is threadedly connected to the second rotating rectangular block.

[0013] Furthermore, the three rotating columns are arranged in a circular array with the center of the rotating cylinder as a reference, and the three second connecting columns are arranged in a circular array with the center of the second ring as a reference.

[0014] Furthermore, each of the connecting rods is slidably adapted to the interior of the rectangular sliding sleeve.

[0015] Furthermore, the accessory blood vessel example 2 and the accessory blood vessel example 1 are both located on the movement path of the guidewire example.

[0016] Furthermore, one end of the guide wire example away from the main blood vessel example is located between the first circular ring and the second circular ring, and one end of the guide wire example away from the main blood vessel example is located on the movement path of the three fixed circular blocks.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The precise rotation assembly avoids the traditional situation where medical staff directly rotate the guide wire by pinching the end of the guide wire, thus avoiding the situation where the diameter of the guide wire is very small and the medical staff cannot accurately rotate the guide wire by hand. It reduces the need for medical staff to repeatedly rotate the guide wire back and forth when the guide wire needs to turn. The precise rotation of the rotating cylinder allows the guide wire to be accurately rotated five degrees each time, allowing medical staff to directly calculate the required turning angle based on the imaging position of the guide wire tip in the image (for example, a turning angle of thirty degrees only requires six operations). ), there is no need for repeated attempts, which significantly reduces invalid operations and shortens the time spent on key surgical steps. At the same time, it avoids the fatigue caused by long-term subtle force of the hands, allowing medical staff to focus more on image observation and path judgment, improving the smoothness of the overall surgical operation. The arc block is rotated to prevent the rotating cylinder from reversing and the fixed round block from conflicting with the guide wire example, eliminating the influence of hand tremors on the rotation of the guide wire example. The uniform rotation of five degrees each time allows the tip of the guide wire example to change direction smoothly, and the turning process of fitting the main blood vessel example is gentler, reducing friction and impact on the endothelium of the main blood vessel example, and reducing the probability of intraoperative complications.

[0018] By adapting the guiding component and the precise rotating component to each other, it can first adapt to the interference of guide wires of different radii. When medical staff hold the grip rod in their hands to advance, the interference of the three fixed round blocks can avoid the situation where the contact area between the fingers and the guide wire is extremely small, and the gripping force is difficult to distribute evenly. The gripping method reduces the deviation of the guide wire caused by finger trembling. BRIEF DESCRIPTION OF THE DRAWINGS

The outer side of the threaded rod 306 is threadedly connected to the rotating rectangular block 2 305, and the end of the threaded rod 306 close to the rotating rectangular block 1 303 is fixedly connected to the handle 307, and the side of the threaded rod 306 close to the handle 307 and the rotating rectangular block 1 303 are provided with a circular limit plate, so that the threaded rod 306 can only play a role of rotation and cannot produce horizontal or vertical displacement.

[0026] The adaptor guide assembly 3 also includes three rotating columns 308, each rotating column 308 is rotatably connected to the side wall of the rotating cylinder 202, and the three rotating columns 308 are arranged in a circular array with the center of the rotating cylinder 202 as a reference.

[0027] The main blood vessel example 1 is provided with a secondary blood vessel example 101 and a secondary blood vessel example 2 102 on the side away from the rotating cylinder 202. The guide wire example 4 is divided into a tip and a tail end. The tip of the guide wire example 4 has good flexibility, while the tail end of the guide wire example 4 is more rigid and can stably transmit the rotational force applied by the medical staff. This is the existing technology and will not be described in detail. The guide wire example 4 is provided with a development marker 5 inside the end away from the rotating cylinder 202. The development marker 5 is made of high-density metal material, which allows doctors to track in real time through imaging equipment. The position, movement and tip state of guidewire example 4 ensure its precise advancement in the human cavity and avoid deviation from the target path. At the same time, the imaging marker 5 is an existing device in the prior art, so it will not be described in detail. The accessory blood vessel example 2 102 and the accessory blood vessel example 1 101 are both located on the movement path of guidewire example 4. The end of guidewire example 4 away from the main blood vessel example 1 is located between the first ring 301 and the second ring 310, and the end of guidewire example 4 away from the main blood vessel example 1 is located on the movement path of the three fixed circular blocks 313.

[0028] The above implementation works as follows: The initialization steps are as follows: The spring 207 is not compressed, and each rotating arc block 206 is located between each two adjacent arc gears 203. Therefore, the inner plane of the rotating arc block 206 conflicts with the inner plane of one of the arc gears 203. The medical staff completes the necessary disinfection and protection work before the operation, and the medical staff now places the tail end of the guide wire example 4 between the first ring 301 and the second ring 310.

[0029] The steps for running the job are as follows: The working steps of the adaptation guide component 3 are as follows: refer to Figure 6 - Figure 10, the medical staff first holds the hand grip 201 with one hand, so that the hand grip 201 is kept in an unrotatable state by the medical staff's grip force, and the medical staff also places the other hand on the handle 307, and the medical staff starts to rotate the handle 307 counterclockwise, and the handle 307 drives the threaded rod 306 to rotate counterclockwise, so that the threaded rod 306 rotates counterclockwise inside the rotating rectangular block 1 303*. Similarly, along with the counterclockwise rotation of the threaded rod 306, the threaded rod 306 causes the rotating rectangular block 2 305 to start moving away from the rotating rectangular block 1 303 along the thread thereon, so that the rotating rectangular block 2 305 starts to pull the fixed rectangular block 304, so that the rotating rectangular block 2 305 drives the fixed rectangular block 304 to also move in the direction away from the first connecting column 302. The block 304 is acted upon by the force of the rotating rectangular block 2 305 , so that the fixed rectangular block 304 drives the first ring 301 to rotate on the rotating cylinder 202 , so that the fixed rectangular block 304 presents an arc-shaped motion, accompanied by the counterclockwise arc-shaped motion of the fixed rectangular block 304 , thereby preventing the rotating rectangular block 2 305 from getting stuck. The rotating rectangular block 2 305 also needs to rotate clockwise with the connection between the fixed rectangular block 304 and the rotating rectangular block 2 305 as the axis, so the threaded rod 306 also presents a counterclockwise swing with the first connecting column 302 as a reference, so that the rotating rectangular block 1 303 also rotates counterclockwise at the connection between the rotating rectangular block 1 303 and the threaded rod 306. Therefore, when the medical staff twists the handle 307, there is no need to suppress the counterclockwise upward swinging trend of the handle 307; As described above, when the first ring 301 rotates counterclockwise, the first ring 301 drives the second ring 310 to rotate counterclockwise as well, so that the second ring 310 drives the second connecting column 311 to rotate counterclockwise as well, and the second connecting column 311 drives the rectangular sliding sleeve 312 to rotate counterclockwise, so the rectangular sliding sleeve 312 pushes the connecting rod 309 through its inner wall to swing toward the center of the second ring 310 with the connection point of the rotating column 308 as the axis, so the connecting rod 309 also slides inside the rectangular sliding sleeve 312, so the three connecting rods 309 all drive the fixed block 313 to move toward a position close to the center of the second ring 310, so the three fixed blocks 313 move toward the direction close to the guide wire example 4, and the three fixed blocks 313 resist the guide wire example 4.

[0030] The working steps of the precision rotation component 2 are as follows: like Figure 3 - Figure 5As described above, as the guidewire example 4 is resisted by the three fixed round blocks 313, the staff still holds the hand grip 201, and the staff no longer holds the handle 307, and the three fixed round blocks 313 always resist the guidewire example 4, so that the staff first inserts the tip of the guidewire example 4 into the main blood vessel example 1, and at the same time the staff begins to hold the hand grip 201 and slowly push the guidewire example 4 to move inside the main blood vessel example 1. As the guidewire example 4 moves, the guidewire example 4 drives the development marker 5 to move synchronously, and the development marker 5 allows the doctor to track the position, movement and tip status of the guidewire example 4 in real time through the imaging equipment, and assists the medical staff to ensure that the guidewire example 4 is accurately advanced in the human body cavity to avoid In order to deviate from the target path, when the guide wire example 4 moves to the position of the auxiliary blood vessel example 1 101 and the auxiliary blood vessel example 2 102, the staff needs to start to turn the rotating cylinder 202 clockwise. At this time, the rotating cylinder 202 drives the arc gear 203 to rotate clockwise, so the outer arc surface 2 of the arc gear 203 begins to continuously slide over the outer arc surface 1 of the rotating arc block 206. Similarly, the rotating arc block 206 continuously compresses the spring 207. When the outer arc surface 2 of the arc gear 203 does not conflict with the outer arc surface 1 of the rotating arc block 206, at this time, if the medical staff no longer turns the rotating arc block 206 clockwise, the spring 207 at this time pushes the rotating arc block 206 to rotate counterclockwise with the rotating rod 205 as the axis through the elastic expansion force, thereby The outer arc surface 2 of the arc gear 203 begins to slide continuously over the outer arc surface 1 of the rotating arc block 206. The inner plane 2 of the rotating arc block 206 continuously rotates clockwise and counterclockwise, and continuously contacts the inner plane 1 of the arc gear 203, making a "clicking" sound. When the medical staff no longer turns the rotating arc block 206 clockwise, the rotating arc block 206 is still stuck between the two adjacent arc gears 203. Similarly, the end of the rotating arc block 206 away from the arc gear 203 contacts the bottom of the inner cavity of the notch 204, thereby preventing the rotating cylinder 202 from turning over. When the number of the arc gears 203 is seventy-two, each time the staff hears a "clicking" sound, it means that the rotating cylinder 202 has rotated five degrees clockwise. The developing marker 5 tracks the status of the guidewire example 4 in real time through the imaging device. At this time, the staff turns the rotating cylinder 202, and the rotating cylinder 202 drives the guidewire example 4 to rotate clockwise. The tip of the guidewire example 4 has good flexibility, and the tail end close to the rotating cylinder 202 is more rigid, which can stably transmit the rotational force applied by the medical staff. When the medical staff rotates the rotating cylinder 202 outside the body, the core wire with strong rigidity at the tail end of the guidewire example 4 will efficiently transmit the rotational torque to the tip of the guidewire example 4. The tip is highly flexible and pre-shaped, so it will rotate around its own axis under the action of torque. Its pre-bent tip will fit the inner wall of the guidewire example 4 like a "steering wheel", thereby changing direction. This is the existing technology and will not be elaborated on.

[0031] The setting of the precise rotation component 2 can avoid the situation in which traditional medical personnel directly pinch the tail end of the guide wire example 4 to rotate it, thereby avoiding the situation in which the medical personnel cannot accurately rotate the guide wire example 4 by hand due to the very small diameter of the guide wire example 4, and reduces the need for medical personnel to repeatedly rotate back and forth when the guide wire example 4 needs to turn, thereby accurately rotating the rotating cylinder 202, so that the guide wire example 4 can also accurately rotate five degrees each time, allowing medical personnel to directly calculate the required turning angle based on the imaging position of the tip of the guide wire example 4 in the image. For example, if a turn of thirty degrees is required, only six operations are required, and there is no need Repeated attempts are required, which significantly reduces invalid operations and shortens the time spent on key surgical steps. At the same time, it avoids fatigue caused by long-term subtle hand force, allowing medical personnel to focus more on image observation and path judgment, improving the smoothness of the overall surgical operation, and preventing the rotating cylinder 202 from reversing and the fixed round block 313 from interfering with the setting of the guide wire example 4 by rotating the arc block 206, thereby eliminating the influence of hand tremors on the rotation of the guide wire example 4. The uniform rotation of five degrees each time allows the tip of the guide wire example 4 to change direction smoothly, and the turning process of fitting the main blood vessel example 1 is gentler, reducing friction and impact on the endothelium of the main blood vessel example 1, and reducing the probability of intraoperative complications.

[0032] By adapting the mutual adaptation of the guiding component 3 and the precise rotating component 2, it first plays the role of being able to adapt to the interference of guidewire examples 4 of different radii. When the medical staff holds the grip rod 201 and pushes it forward, the interference of the three fixed round blocks 313 can avoid the situation where the contact area between the fingers and the guidewire example 4 is extremely small and the gripping force is difficult to be evenly distributed. Thus, the gripping method reduces the situation where the guidewire example 4 deviates due to the shaking of the fingers.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
