Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a balloon guidewire threading device. Background Art

[0002] A guidewire is a thin, long metal or plastic wire that is often used to guide the placement of other devices or implants. A guidewire usually has good elasticity and rigidity so that it can be punctured and guided in narrow anatomical channels. In surgery, a guidewire is usually inserted into the human body through a blood vessel, catheter, or catheter cannula. A balloon catheter is an interventional medical device that acts like a tool that is sent to a blocked or narrowed sewer to clear the blockage. The structure of a balloon catheter is, from the distal end to the tip, a seat, a hypotube, a transition tube, an outer lumen, an expansion balloon, and a catheter tip. In addition, an inner lumen is inserted inside the outer lumen, the expansion balloon, and the catheter tip to facilitate the passage of the guidewire.

[0003] The Chinese Patent Network discloses "a convenient balloon guidewire introducer", with the announcement number CN216755180U, which includes a base, characterized in that: a guidewire introduction bracket is arranged at the upper end of the base, a balloon placement slot is arranged in the middle of the guidewire introduction bracket, guidewire introduction devices are arranged at both ends of the guidewire introduction bracket, and the guidewire introduction device includes a transparent shell, a horn perforation is arranged inside the transparent shell, one end of the horn perforation is a guidewire inlet, and the other end of the horn perforation is a guidewire outlet, the inner diameter of the horn perforation gradually decreases along the guidewire inlet to the guidewire outlet direction, and a magnifying glass is connected to the upper end of the transparent shell through a pivot, and the magnifying glass can rotate around the pivot; by setting a balloon placement slot for fixing the balloon catheter and an arc-shaped horn perforation structure, on the one hand, the balloon catheter can be fixed and positioned, and on the other hand, the guidewire can be guided to quickly align and enter the balloon catheter, so that medical staff can complete the guidewire placement within a few seconds.

[0004] The balloon contains medicine and the guidewire is attached with blood. If the guidewire is directly inserted, the blood and medicine will come into contact, and the blood will dilute the medicine, affecting the efficacy and the treatment effect. Although the existing technology can facilitate the insertion of the catheter and the guidewire, it is impossible to wipe off the blood. Clinically, some medical staff wipe off the blood with gauze dipped in saline before insertion, which further increases the labor intensity under the premise of already high-intensity work. At the same time, since the insertion of balloons and guidewires is often used in operations such as heart stents, it takes a long time to manually wipe off the blood, which will consume a lot of precious rescue time and directly affect the success rate of the operation.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Fig. 9 In one or more embodiments, a balloon guidewire threading device is provided, including a shell 100, wherein a guidewire fixing assembly and a catheter fixing assembly are sequentially arranged inside the shell 100 from left to right, wherein the catheter fixing assembly is used to fix the balloon catheter, wherein the guidewire fixing assembly includes a telescopic motor 101 and a No. 1 clamping plate 102, wherein the telescopic motor 101 is arranged inside the shell 100, wherein a No. 1 cavity 133 is provided inside the shell 100, wherein an output end of the telescopic motor 101 extends to the inside of the No. 1 cavity 133 and is connected to the surface of the No. 1 clamping plate 102, wherein a placement groove is provided on the surface of the No. 1 clamping plate 102, wherein an erasing pad 103 is detachably connected to the inner wall of the placement groove, wherein the number of the guidewire fixing assemblies is at least two, wherein a plurality of No. 1 clamping plates 102 limit a No. 1 clamping cavity 104 matching the size of the guidewire, wherein a conveying unit is arranged inside the No. 1 clamping plate 102, wherein the conveying unit is used to convey the guidewire in the No. 1 clamping cavity 104 toward the direction of the catheter fixing assembly, and an anti-slip pad 122 is arranged at the bottom of the shell 100.

[0027] In this embodiment, after wiping blood off the guide wire head in advance, the guide wire is placed in the No. 1 cavity 133, and then the telescopic motor 101 causes the No. 1 clamping plate 102 to move toward the center of the No. 1 cavity 133 until different No. 1 clamping plates 102 abut against each other. At this time, the erasing pad 103 will contact the surface of the guide wire and fix the guide wire. When the conveying unit is working, it will cause the guide wire to move toward the catheter fixing component, thereby achieving the guide wire being inserted into the catheter. During this process, the guide wires at different positions are in contact with the erasing pad 103, thereby achieving the guide wire erasing effect before the guide wire and the balloon are inserted, thereby directly reducing the operating intensity of medical staff. It should be noted that wiping blood off the guide wire head in advance can avoid the guide wire not being in contact with the catheter. The blood on the surface of the guidewire that is in contact with the wiping pad comes into contact with the drug in the balloon, affecting the efficacy of the drug; the number of guidewire fixing components is at least two, and six are used in this application. The specific number is adjusted according to actual conditions, and the shape and size of the No. 1 clamping plate 102 can be adjusted according to actual conditions, but it should be noted that when multiple No. 1 clamping plates 102 abut against each other, a No. 1 clamping cavity 104 matching the size of the guidewire is formed, which can be replaced by a trapezoid or rectangle with an arc surface; the provision of the anti-slip pad 122 can effectively improve the stability of the outer shell 100 after it is placed, and a magnetic sheet or a counterweight can be installed in the anti-slip pad 122 as needed to make the center of gravity of the outer shell 100 downward, which can further improve the stability of the outer shell 100.

[0028] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Fig. 9 In some embodiments, a groove 105 and a driving groove 106 are connected to each other inside the No. 1 clamping plate 102, and the conveying unit includes a No. 1 driving motor 107, a No. 1 gear 108 and a No. 2 gear 109. The inner wall of the groove 105 is movably connected with a movable rod 110, and the other end of the movable rod 110 extends to the inside of the driving groove 106 and is connected to the surface of the No. 1 gear 108. The No. 1 driving motor 107 is arranged in the No. 1 clamping plate 102, and the output end of the No. 1 driving motor 107 extends to the inside of the driving groove 106 and is connected to the surface of the No. 2 gear 109. The surface of the No. 1 gear 108 is meshed with the surface of the No. 2 gear 109. A conveying wheel 111 is arranged on the surface of the movable rod 110 and located inside the groove 105. A pressing pad 124 is arranged on the surface of the conveying wheel 111, and an anti-slip pattern is arranged on the surface of the pressing pad 124. The centers of the No. 1 clamping cavity 104 and the No. 3 clamping cavity are on the same horizontal line.

[0029] In this embodiment, after the No. 1 telescopic motor 101 is started, the No. 1 clamping plate 102 will be displaced to the center position until different No. 1 plates abut against each other. At this time, the erasing pad 103 and the squeezing pad 124 are in contact with the guide wire, and the No. 1 driving motor 107 is started. Under the continuous engagement of the No. 1 gear 108 and the No. 2 gear 109, the movable rod 110 can drive the squeezing pad 124 to rotate through the conveying wheel 111. When the squeezing pad 124 contacts the guide wire, the resilience of the squeezing pad 124 will squeeze the guide wire, and the squeezing pad 124 will apply a guide wire deflection force to achieve the displacement of the guide wire as the conveying wheel 111 rotates; the squeezing pad 124 is set to protect the guide wire to prevent the conveying process from In case the guide wire is damaged, the anti-slip texture is set to increase the friction between the squeezing pad 124 and the guide wire, so as to reduce the probability of the delivery wheel 111 idling and failing to deliver the guide wire; when the erasing pad 103 is in contact with the guide wire, the resilience of the erasing pad 103 will squeeze the guide wire, so as to ensure that the blood on the surface of the guide wire can be continuously wiped off during the subsequent displacement of the guide wire, and the deflection force applied by the squeezing pad 124 to the guide wire during rotation must be greater than the elastic force of the erasing pad 103 on the guide wire, so as to achieve normal displacement of the guide wire; since the centers of the No. 1 clamping cavity 104 and the No. 3 clamping cavity are on the same horizontal line, the guide wire can directly enter the fixed catheter during the displacement process, so as to achieve the guide wire threading.

[0030] See also Figure 1 , Figure 6 , Figure 7 and Fig. 9 In some embodiments, the catheter fixing assembly includes a placement plate 112, a driving member and a second clamping plate 113. The interior of the housing 100 is provided with a second cavity 114. The first cavity 133 and the second cavity 114 are sequentially connected. The placement plate 112 is arranged on the inner wall of the second cavity 114. There is a gap between the bottom of the placement plate 112 and the bottom of the second cavity 114. The surface of the placement plate 112 is provided with an arc groove 115 and a through hole 116. The driving member is arranged inside the housing 100. The driving member is used to drive the second clamping plate 113. The holding plate 113 is displaced toward the arc groove 115, and there are multiple No. 2 clamping plates 113, all of which face the arc groove 115. The side of the No. 2 clamping plate 113 facing the arc groove 115 is in an arc shape. The No. 2 clamping plate 113 and the arc groove 115 can limit a No. 2 clamping cavity 125 that matches the size of the balloon catheter. The centers of the No. 1 clamping cavity 104 and the No. 3 clamping cavity are on the same horizontal line, the size of the perforation 116 is larger than the size of the balloon, and the balloon is located in the perforation 116 and is suspended.

[0031] In this embodiment, the catheter is placed on the placement plate 112, wherein the balloon of the catheter is located in the perforation 116 to prevent the balloon from being damaged or even contaminated during the fixation and insertion process. Subsequently, the No. 2 clamping plate 113 is displaced toward the arc groove 115 by the driving member. During this process, the catheter can be pushed toward the arc groove 115. When the No. 2 clamping plates 113 abut against each other, the catheter is located in the No. 2 clamping cavity 125 restricted by the No. 2 clamping plates 113 and the arc groove 115, thereby achieving the fixation of the catheter. The number of No. 2 clamping plates 113 is adjusted according to actual conditions.

The surfaces of the transmission roller 119 and the internal threaded barrel 120 are both abutted against the surface of the transmission belt 118.

[0033] In this embodiment, the No. 2 driving motor 117 is started to rotate the transmission roller 119. When the transmission roller 119 rotates, the transmission belt 118 is transmitted, so that the internal threaded tube 120 rotates. By adjusting the rotation direction of the internal threaded tube 120, the threaded rod 121 drives the displacement direction of the No. 2 clamping plate 113; the number of threaded rods 121 and internal threaded tubes 120 matches the number of the No. 2 clamping plate 113; wherein the driving member structure includes but is not limited to the above structure.

Under the continuous meshing of the No. 1 gear 108 and the No. 2 gear 109, the movable rod 110 can drive the squeezing pad 124 to rotate through the conveying wheel 111. When the squeezing pad 124 contacts the guide wire, the resilience of the squeezing pad 124 will squeeze the guide wire, and the squeezing pad 124 will apply a guide wire deflection force to achieve the displacement of the guide wire as the conveying wheel 111 rotates. Since the centers of the No. 1 clamping cavity 104 and the No. 3 clamping cavity are on the same horizontal line, the guide wire can directly enter the fixed catheter during the displacement process to achieve the guide wire penetration into the catheter; The camera 128 is located above one end of the catheter, and the guidewire will enter the catheter through this end. Therefore, the camera 128 can take pictures of the guidewire and the catheter insertion position and display them through the display screen 132, so that medical staff can know the insertion situation. The controller 127 will display the working status of the relevant structure through the display screen 132, and at the same time send the relevant data to the wireless communicator and display it through the display, thereby achieving the effect of remote monitoring.
