Description

Technical Field

[0001] The present invention relates to the technical field of cardiovascular interventional treatment, and in particular to a cardiovascular and cerebrovascular interventional treatment device for cardiology. Background Art

[0002] Catheter interventional drug delivery in the Department of Cardiology is a cutting-edge technology for the diagnosis and treatment of cardiovascular diseases. With the precise guidance of medical imaging equipment, a special catheter is inserted into the femoral artery, radial artery and other blood vessels by percutaneous puncture. The catheter is then accurately delivered to the diseased site of the heart or blood vessels based on the vascular pathway. On this basis, the catheter is used to release the drugs needed for treatment directly to the lesion site, thereby achieving efficient local drug effects and significantly improving the treatment effect.

[0003] This treatment method can be used for a variety of cardiovascular diseases. Taking the treatment of coronary heart disease as an example, by delivering thrombolytic drugs and antiplatelet drugs to blocked coronary arteries, it can effectively dissolve blood clots, prevent further blood clot formation, and restore myocardial blood supply. For arrhythmias, antiarrhythmic drugs are delivered to regulate the electrophysiological activity of the heart and restore normal heart rhythm. Compared with traditional oral or intravenous administration methods, catheter interventional drug delivery therapy has significant advantages such as direct drug action, high local drug concentration, and relatively small systemic side effects, providing patients with cardiovascular diseases with a more accurate and efficient treatment plan.

[0004] However, when patients with cardiovascular and cerebrovascular diseases currently receive vascular interventional catheter treatment, a longer catheter needs to be inserted into the human body. Due to the long length of the catheter, in order to ensure its smooth entry into the body, the external part of the catheter needs to be fixed. Currently, the commonly used fixation methods mainly include fixation with medical tape and fixation with a fixing belt with a fixing plate. Fixation with medical tape has problems such as small sticking range, only applicable to small soft catheters, and short fixation time. Once the tape falls off and the catheter slides, it will aggravate the patient's pain. The fixing belt with a fixing plate has a hard texture and will reduce the patient's comfort when placed on the patient's body. In addition, some adhesive tape fixing devices lack catheter fixing sockets, which makes the catheter easy to move, affecting the treatment process. At the same time, during catheter treatment, since most drugs need to be refrigerated, low-temperature drugs are prone to induce stress responses in the human body when entering the human body.

[0047] like Figures 1 to 9 As shown, an embodiment of the present invention provides a cardiovascular interventional treatment device for cardiology, including an annular rail 1, wherein the interior of the annular rail 1 is slidably connected with catheter holders 2 arranged in an annular shape at equal intervals, and a hanging member 3 is fixedly installed on the inner side of the annular rail 1; the catheter holder 2 includes an adjustment component 21, which is movably installed inside the annular rail 1, and a limiting component 22 is fixedly installed on the outer side of the adjustment component 21, and the adjustment component 21 is clamped with the annular rail 1 through the limiting component 22, and a lifting component 23 is fixedly connected to the bottom of the adjustment component 21, and a connecting component 24 is fixedly installed on the inner side of the lifting component 23, a heating group 25 is provided on the inner side of the connecting component 24, and an elastic group 26 is provided on the outer side of the connecting component 24.

[0048] The catheter holder 2 arranged in a ring shape with equal intervals inside the annular rail 1 can slide flexibly to meet different treatment needs. The adjustment component 21 of the catheter holder 2 moves in the annular rail 1. When the position needs to be fixed, it is connected to the annular rail 1 through the limit component 22 to ensure stability. The lifting component 23 connected to the bottom of the adjustment component 21 can achieve height adjustment to meet the height requirements in different treatment scenarios. The connecting component 24 on the inner side of the lifting component 23 plays the role of connecting various parts. The heating group 25 arranged on the inner side can heat the liquid medicine in the catheter to avoid the adverse effects of the liquid medicine on the human body due to the low temperature. The elastic group 26 on the outer side of the connecting component 24 plays a role in operations such as winding the catheter. For example, when winding, the elastic group 26 can be compressed through relevant operations to release the limit of the adjustment handle 265, thereby driving the relevant components to realize the winding of the catheter. After the winding is completed, the elastic group 26 is reset to achieve fixation, ensuring the stability of the catheter winding. The overall device works in coordination to achieve flexible adjustment and effective fixation of the catheter in cardiovascular and cerebrovascular interventional treatment.

[0049] like Figures 1 to 3As shown, the hanging member 3 includes a base ring 31, and connecting rods 32 are fixedly installed on the outer side of the base ring 31 at equal intervals. The outer end of the connecting rod 32 is fixedly connected to the inner lower end of the annular rail 1, and a hanging rod 33 is fixedly installed on the top of the base ring 31. A hanging top plate 34 is fixedly installed on the top of the hanging rod 33. Hanging installation holes 35 are opened at equal intervals on the outer side of the bottom of the hanging top plate 34. The hanging installation holes 35 are all set as countersunk holes. The outer edges and corners of the annular rail 1 and the hanging plate are all set as arcs. The base ring 31 serves as a core connecting component, and the connecting rods 32 fixed on the outer side at equal intervals can evenly connect the base ring 31 with the inner lower end of the annular rail 1 to ensure the stability of the connection and the uniformity of the force. The hanging rods on the top of the base ring 31 33 extends vertically upward and is used to transfer the gravity and other forces of the entire device. The hanging top plate 34 on the top of the hanging rod 33 provides an operating plane for connection with the treatment equipment. The countersunk hanging installation holes 35 opened at equal intervals on the outer side of the bottom can be used with matching bolts and other connecting parts to fasten and install through the countersunk holes. The design of the countersunk holes can make the bolt heads sink into the holes to keep the surface smooth, which is both beautiful and avoids the protruding parts from interfering with other parts or operations. In addition, the outer edges and corners of the annular rail 1 and the hanging plate are set to be arc-shaped, which can effectively prevent scratches on operators or other equipment during installation, movement or use, and can also reduce damage to components caused by collisions, thereby improving the safety and durability of the device.

[0050] like Figures 1 to 3 and Figures 8 to 9 As shown, the shifting assembly 21 includes a slider 211, which is slidably connected to the inside of the annular rail 1, a chassis 212 is fixedly installed at the bottom of the slider 211, a disc 213 is rotatably connected to the bottom of the chassis 212, a first screw 214 is threadedly connected to the middle of the bottom side of the disc 213, the end of the first screw 214 passes through the chassis 212, and the bottom of the chassis 212 is arranged in a ring shape with equal intervals to provide limiting holes 215, the top of the first screw 214 is inserted into the inside of the limiting hole 215, and the limiting assembly 22 includes an external frame 221 and a clamping hole 222, the external frame 221 is fixedly connected to the outside of the slider 211, and the external frame 221 is slidably connected to On the outer surface of the annular rail 1, a fixing frame 223 is fixedly installed on the outer side of the external frame 221, a limiting spring 224 is fixedly connected inside the fixing frame 223, a push block 225 is fixedly connected to the end of the limiting spring 224, a clamping block 226 is fixedly connected to the end of the push block 225, an end of the clamping block 226 passes through the fixing frame 223, clamping holes 222 are arranged in a ring shape at equal intervals and are opened on the inner side of the annular rail 1, an end of the clamping block 226 is inserted into the inner side of the clamping hole 222, a connecting shaft 227 is fixedly connected to the outer side of the clamping block 226, an end of the connecting shaft 227 passes through the fixing frame 223 and a bridge handrail 228 is fixedly installed, and an anti-slip handrail cover is provided on the outer surface of the bridge handrail 228.

[0051] The shifting assembly 21 and the limiting assembly 22 work together to realize flexible adjustment and precise fixation of the position and direction of the catheter holder 2 on the annular rail 1. When the position of the catheter holder 2 on the annular rail 1 needs to be adjusted, the bridge armrest 228 is pulled to drive the connecting shaft 227 to move, so that the block 226 is separated from the hole 222. At this time, the slider 211 can slide freely in the annular rail 1, thereby adjusting the position of the catheter holder 2 to meet the needs of different treatment scenarios. After the position is determined, the bridge armrest 228 is released, and the limiting spring 224 pushes the push block 225 to insert the block 226 into the corresponding hole 222, and the slider 2 11 is fixed on the annular rail 1. If the direction of the catheter holder 2 is to be adjusted, the first screw rod 214 at the bottom of the disc 213 can be loosened to disengage it from the limiting hole 215 at the bottom of the bottom of the chassis 212, and then the disc 213 is rotated to drive the chassis 212 and the entire catheter holder 2 connected thereto to rotate to achieve direction adjustment. After the direction adjustment is completed, the first screw rod 214 is tightened again to insert it into the limiting hole 215 to fix the relative position of the chassis 212 and the disc 213, thereby ensuring that the catheter holder 2 is stable during use, and the anti-slip handrail cover on the bridge handrail 228 is convenient for the operator to grasp and enhance the stability of the operation.

[0052] like Figures 1 to 5 As shown, the lifting assembly 23 includes a vertical rail 231, which is fixedly connected to the bottom of the disc 213. The vertical rail 231 is slidably connected to a movable block 232 inside the vertical rail 231. A limit plate 233 is fixedly installed on the outer side of the movable block 232. The limit plate 233 is T-shaped when viewed from above. The outer ends of the limit plate 233 are both threadedly connected to a second screw rod 234. The end of the second screw rod 234 passes through the limit plate 233. The inner side of the movable block 232 is connected to the outer side of the assembly 24. The connecting component 24 includes a fixed sleeve 241, which is fixedly connected to the side of the movable block 232 away from the limiting plate 233. The inner side of the fixed sleeve 241 is rotatably connected to a rotating shaft 242, and a frame 243 is fixedly installed on the inner side of the rotating shaft 242. The top of the fixed sleeve 241 is threadedly connected to a third screw 244, and the end of the third screw 244 passes through the fixed sleeve 241. The elastic group 26 is arranged in the middle of the outer end of the frame 243, and the heating group 25 is arranged inside the elastic group 26.

[0053] The lifting assembly 23 and the connecting assembly 24 work together to realize the position and angle adjustment of the heating group 25 and the elastic group 26 to meet different treatment needs. When the height needs to be adjusted, the second screws 234 on both sides of the limit plate 233 are rotated to make it break away from the close contact with the vertical rail 231. At this time, the movable block 232 can slide freely inside the vertical rail 231. Since the inner side of the movable block 232 is connected to the connecting assembly 24, the lifting of the movable block 232 can drive the connecting assembly 24, the heating group 25 and the elastic group 26 to move up and down synchronously, thereby adjusting their height positions to meet the height requirements in different treatment scenarios. After fixing, rotate the second screw 234 in the opposite direction so that its end is against the vertical rail 231 to fix the movable block 232. When the angle needs to be adjusted, loosen the third screw 244 on the top of the fixing sleeve 241, and the rotating shaft 242 can rotate freely inside the fixing sleeve 241. Since the frame 243 is fixedly installed inside the rotating shaft 242, the heating group 25 and the elastic group 26 are arranged at relevant positions of the frame 243, the rotation of the rotating shaft 242 can drive the frame 243, the heating group 25 and the elastic group 26 to rotate together to achieve angle adjustment. After the adjustment is completed, tighten the third screw 244 to fix the position of the rotating shaft 242 to ensure the stability of the overall structure during use.

[0054] like Figures 1 to 7As shown, the elastic group 26 includes a sleeve 261, which is fixedly connected to the middle part of the side of the frame 243 away from the movable block 232, and the sleeve 261 is rotatably connected to a turntable 262 inside the sleeve 261, and a buffer torsion spring 263 is fixedly connected to the inner side of the turntable 262, and a circular plate 264 is fixedly installed on the inner end of the buffer torsion spring 263. The heating group 25 is arranged on the side of the circular plate 264 close to the movable block 232, and an adjusting handle 265 is rotatably connected to the outer side of the sleeve 261, and the inner side of the adjusting handle 265 is connected to the turntable 262 inside the sleeve 261. A movable groove 266 is provided on one side of the sleeve 261, and a telescopic spring 267 is fixedly connected to the inside of the movable groove 266. A displacement block 268 is fixedly connected to the end of the telescopic spring 267, and a limiting pin 269 is fixedly connected to the outer end of the displacement block 268. Positioning holes 270 are evenly spaced on the outer side of the adjusting handle 265. The end of the pin 269 is inserted into the inside of the positioning hole 270, and the outer side of the displacement block 268 is fixedly connected with a push plate 271; the heating group 25 includes a base shaft 251, the base shaft 251 is fixedly connected to the middle part of one side of the circular plate 264 close to the movable block 232, the outer ends of the base shaft 251 are fixedly connected with side plates 252, the upper and lower ends of the inner side of the side plate 252 are fixedly connected with a winding shaft 253, the outer surface of the base shaft 251 is fixedly connected with a heating wire 254, and the inner sides of the two side plates 252 are located outside the heating wire 254. The spacing lever 255 is fixedly connected in a ring shape at equal intervals, and the lower end of the inner side of the side plate 252 away from the movable block 232 is fixedly connected with a temperature sensor 256, and the temperature measuring end of the temperature sensor 256 is fitted and connected with the outer surface of a winding shaft 253, and the first screw 214, the second screw 234 and the third screw 244 are all configured as hand-tightening screws.

[0055] The elastic group 26 works with the heating group 25 to complete the functions of catheter winding, heating and temperature monitoring. When the catheter needs to be wound, the push plate 271 is pushed to make the displacement block 268 compress the telescopic spring 267, and the limit pin 269 is disengaged from the positioning hole 270 on the outside of the adjustment handle 265, so as to release the limit of the adjustment handle 265. The adjustment handle 265 is rotated to drive the turntable 262 to rotate, and the buffer torsion spring 263 on the inside of the turntable 262 is twisted accordingly, and at the same time, the circular plate 264 connected thereto is driven to rotate. The rotation of the circular plate 264 causes the base shaft 251 and the side plate 252 fixed on one side thereof to rotate, and the winding shaft 251 on the side plate 252 is rotated. 3 are staggered and rotated in a circle to realize the winding of the catheter. After the winding is completed, the push plate 271 is released, the telescopic spring 267 is reset to push the displacement block 268, so that the limit pin 269 is inserted into the positioning hole 270, the adjustment handle 265 is fixed, and the winding catheter is stabilized. During the winding process, the electric heating wire 254 is started to radiate and heat the wound catheter to prevent the low temperature of the liquid medicine from affecting the human body. The interval lever 255 prevents the catheter from directly contacting the electric heating wire 254 and being melted. The temperature sensor 256 monitors the outer surface temperature of the winding shaft 253 in real time to ensure accurate temperature control, and the hand-tightened screw is convenient for the operator to quickly adjust and improve the convenience of operation.

[0056] The workflow of the technical solution provided by the present invention is as follows:

[0057] During use, the catheter is rolled up in order on the outer surface of the winding shaft 253 of the heating group 25. When the height needs to be adjusted, the operator twists the second screw rod 234 to disengage it from the contact position with the vertical rail 231. At this time, the movable block 232 can slide freely inside the vertical rail 231. By adjusting the sliding of the movable block 232, the entire connecting assembly 24 and the elastic group 26 can be moved up and down, thereby accurately adjusting the height of the catheter holder 2. After completing the height adjustment, loosen the first screw rod 214 to disengage it from the limiting hole 21 5, the fixed plate is operated to rotate at the bottom of the chassis 212, and the rotation of the fixed plate drives the vertical rail 231 at the bottom of the slider 211 to rotate synchronously, thereby realizing the flexible adjustment of the overall direction of the catheter holder 2. After the adjustment is completed, the first screw rod 214 is twisted again to insert it into the inner side of the limiting hole 215 to realize the clamping and fixing of the vertical rail 231; at the same time, the second screw rod 234 is adjusted to make it fit closely to the outer surface of the vertical rail 231, further assisting in fixing the movable block 232, and ensuring the stability of the catheter holder 2 during use.

[0058] After completing the direction adjustment of the catheter holder 2, the operator drives the connecting shaft 227 to pull the block 226 out of the inner side of the hole 222 by pulling out the bridge handrail 228. After the block 226 is out of the hole 222, the slider 211 can slide freely inside the annular rail 1. By adjusting the sliding of the slider 211 inside the annular rail 1, the position of the catheter holder 2 on the annular rail 1 can be flexibly adjusted according to specific treatment needs, so as to achieve fine adjustment of the catheter fixing position. In addition, the device also has unique advantages in installation. The hanging top plate 34 can be tightly fitted on the treatment equipment. The base ring 31 at the bottom of the hanging rod 33 is assisted in hanging and installing by using bolts to cooperate with the hanging installation hole 35. The outer side of the base ring 31 is connected to the annular rail 1 through the connecting rod 32, so that the device can be conveniently hung and installed, which greatly improves the flexible adaptability of the device during use and meets the needs of different treatment scenarios.

[0059] When winding the catheter, the catheter is accurately inserted between the inner sides of the winding shaft 253, and the push plate 271 is pushed to squeeze the telescopic spring 267, so that the telescopic spring 267 is in a compressed state. At this time, the displacement block 268 is pulled out of the limit pin 269, so that it is out of the positioning hole 270, and the limit of the adjustment handle 265 is released. The adjustment handle 265 is twisted to drive the circular plate 264 to rotate. The rotation of the circular plate 264 drives the base shaft 251 and the side plate 252 at its end to rotate. As the side plate 252 rotates, the two winding shafts 253 rotate in a circle, and the winding shafts 253 rotate relative to each other. The catheter is effectively rolled up by staggered rotation, so that the catheter is tightly wound on the outer surfaces of the two winding shafts 253. After the rolling is completed, the push plate 271 is released, the telescopic spring 267 is reset, and the displacement block 268 is pushed to drive the limit pin 269 to move forward. The limit pin 269 is inserted into the positioning hole 270 to fix the adjustment handle 265, ensuring that the catheter is stably rolled up on the outer surface of the winding shaft 253. Since the rolling process is in a circular state, the catheter is avoided from being bent 90 degrees, which ensures the normal delivery of the drug solution during the rolling period and prevents the collapse of the catheter.

[0060] In terms of heating, the electric heating wire 254 is started to operate. The electric heating wire 254 is located on the inner side of the wound catheter. The catheter is heated by radiation, which effectively increases the temperature of the medicine liquid inside the catheter to avoid adverse effects on the human body caused by too low a temperature of the medicine liquid. At the same time, the spacing bar 255 arranged on the outer surface of the electric heating wire 254 can effectively isolate the catheter from the electric heating wire 254 to prevent the catheter from directly contacting the electric heating wire 254 and being melted, thereby further improving the heating effect. During the heating process, the temperature of the outer surface of the winding shaft 253 is detected in real time by the temperature sensor 256 to achieve precise control of the temperature of the medicine liquid. In addition, when it is necessary to adjust the angles of the connecting component 24, the heating group 25 and the elastic group 26, it is only necessary to loosen the third screw 244 to adjust the rotation of the rotating shaft 242 inside the fixing sleeve 241, thereby achieving flexible adjustment of the angle of the catheter holder 2, thereby further improving the convenience of the device during use.
