Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically, to a catheter delivery mechanism and an intravascular shockwave therapy device. Background Technology

[0002] Interventional therapy is a minimally invasive treatment using modern high-tech methods. Guided by medical imaging equipment, specialized catheters, guidewires, and other precision instruments are introduced into the body to diagnose and treat internal lesions. A shockwave catheter consists of a balloon and one or more pairs of discharge electrodes to form a shockwave generator device. The electrodes are connected to a high-voltage pulse power supply unit via connectors. When the balloon is placed at the calcified lesion in the blood vessel, the system applies high-voltage pulses to generate shockwaves at the electrodes. These shockwaves selectively destroy calcified plaques in the blood vessel wall while avoiding damage to the vessel wall.

[0003] Traditionally, medical staff manually push the interventional catheter. During the procedure, the workload for medical staff is heavy, and long-term operation can easily lead to hand tremors, affecting the stability of the catheter and increasing the difficulty of the procedure. Although there are some catheter pushing institutions on the market, most of them push the catheter unilaterally, which is difficult to match the flexibility of manual pushing. Summary of the Invention

[0004] To overcome the shortcomings of the existing methods, this application provides a catheter pushing mechanism and an intravascular shockwave therapy device, which can solve the problem that the traditional method relies on medical staff to manually push the interventional catheter. During the operation, the medical staff have a high labor intensity, and long-term operation can easily affect the stability of the catheter due to hand tremors, thereby increasing the difficulty of the operation. In addition, although there are some pushing mechanisms on the market that push the catheter, most of them push in one direction and cannot match the flexibility of manual pushing.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A catheter delivery mechanism and an intravascular shockwave therapy device include a support component and a delivery component.

[0007] The support assembly includes a support base, a fixed ring, and a rotating ring. The fixed ring is fixedly connected to the support base, and the rotating ring is rotatably disposed within the rotating ring.

[0008] The pushing assembly includes a fixed plate, a first rotating roller, a second rotating roller, a shock waveguide, a connecting plate, and a motor. The fixed plate is fixedly connected to the rotating ring. The first rotating roller is rotatably disposed on one side of the first rotating roller, and the second rotating roller is rotatably disposed on one side of the first rotating roller. The shock waveguide passes through the first rotating roller and the second rotating roller. The connecting plate is fixedly connected to the rotating ring. The motor is mounted on one side of the connecting plate and is drively connected to the first rotating roller and the second rotating roller.

[0009] In one specific implementation, the first rotating roller is fixedly inserted through a first rotating shaft, which rotatably passes through the fixed plate; the second rotating roller is fixedly inserted through a second rotating shaft, which rotatably passes through the fixed plate.

[0010] In the above implementation process, a first rotating shaft is set to rotate and install the first rotating roller to the bottom fixed plate, and a second rotating shaft is set to rotate and install the second rotating roller to the bottom fixed plate.

[0011] In one specific implementation, the motor output end is connected to the first rotating shaft, the first rotating shaft is fixedly sleeved with a first gear, the second rotating shaft is fixedly sleeved with a second gear, and the first gear and the second gear mesh with each other.

[0012] In the above implementation process, by setting the first gear and the second gear to mesh, when the motor drives the first rotating shaft to rotate, the first rotating shaft drives the first rotating roller and the first gear to rotate. The first gear meshes and drives the second gear to rotate. The second gear drives the second rotating shaft to rotate. The second rotating shaft drives the second rotating roller to rotate. The first rotating roller and the second rotating roller rotate synchronously in opposite directions, thereby pushing the shock wave guide tube.

[0013] In one specific implementation, a limiting ring is provided at the end of the rotating ring, and a limiting groove is provided on the fixed ring, with the limiting ring rotatably disposed within the limiting groove.

[0014] In the above implementation process, a limiting ring is set to rotate within the limiting groove to achieve stable rotation of the rotating ring and maintain and fix the concentricity of the ring.

[0015] In one specific implementation, two fixed rings are symmetrically arranged, and a handle is provided on the outer side of the rotating ring.

[0016] In the above implementation process, a handle is provided to facilitate the rotation of the rotating ring by operating the handle.

[0017] In one specific implementation, the support base includes a base plate and a support column, the support column being disposed on the top of the base plate, and the fixing ring being disposed on the top of the support column.

[0018] Secondly, this utility model also provides an intravascular shockwave therapy device including the aforementioned catheter delivery mechanism and a treatment component. The treatment component includes a shockwave generator and a connecting cable, the connecting cable being electrically connected to the shockwave generator, and the shockwave catheter being connected to the connecting cable.

[0019] In one specific implementation, the shock wave duct is provided with a duct seat at its end, and the duct seat is connected to the connecting cable.

[0020] The advantages of this embodiment are: by setting a support base, a fixed ring, a rotating ring, a fixed plate, a first rotating roller, a second rotating roller, a shock wave catheter, a connecting plate, and a motor, and by setting a fixed ring and a rotating ring, forward and reverse rotation adjustment can be achieved while pushing, thereby mimicking the rotation adjustment when medical personnel push. The motor drives the first rotating roller and the second rotating roller to rotate synchronously, thereby realizing the pushing of the shock wave catheter. Controlling the forward and reverse rotation of the motor, thereby mimicking the forward and backward adjustment when medical personnel push, greatly improves flexibility and reduces the fatigue of medical personnel.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0027] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0028] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0029] Please see Figures 1-4 This application provides a catheter delivery mechanism and an intravascular shockwave therapy device, including a support component 100 and a delivery component 200.

[0030] Please see Figure 1 , 2 3. The support assembly 100 includes a support base 110, a fixed ring 120 and a rotating ring 130. The fixed ring 120 is fixedly connected to the support base 110, and the rotating ring 130 is rotatably disposed within the rotating ring 130.

[0031] The rotating ring 130 has a limiting ring 131 at its end, and the fixed ring 120 has a limiting groove 121. The limiting ring 131 is rotatably disposed in the limiting groove 121. By setting the limiting ring 131 to rotate in the limiting groove 121, the rotating ring 130 can be rotated stably and the concentricity with the fixed ring 120 can be maintained.

[0032] It should be noted that there are two fixed rings 120 arranged symmetrically, and a handle 132 is provided on the outer side of the rotating ring 130. By providing the handle 132, it is convenient to drive the rotating ring 130 to rotate by operating the handle 132.

[0033] In one specific implementation, the support base 110 includes a base plate 111 and a support column 112, with the support column 112 disposed on the top of the base plate 111 and the fixing ring 120 disposed on the top of the support column 112.

[0034] Please see Figure 1 , 2 3 and 4, the pushing component 200 includes a fixed plate 210, a first rotating roller 220, a second rotating roller 230, a shock wave guide 240, a connecting plate 250, and a motor 270. The fixed plate 210 is fixedly connected to the rotating ring 130. The first rotating roller 220 is rotatably disposed on one side of the first rotating roller 220. The second rotating roller 230 is rotatably disposed on one side of the first rotating roller 220. The shock wave guide 240 passes between the first rotating roller 220 and the second rotating roller 230. The connecting plate 250 is fixedly connected to the rotating ring 130. The motor 270 is installed on one side of the connecting plate 250 and is drively connected to the first rotating roller 220 and the second rotating roller 230.

[0035] The first rotating roller 220 is fixedly connected to the first rotating shaft 221, which rotates through the fixed plate 210. The second rotating roller 230 is fixedly connected to the second rotating shaft 231, which rotates through the fixed plate 210. The first rotating shaft 221 is used to rotatably mount the first rotating roller 220 onto the fixed plate 210, and the second rotating shaft 231 is used to rotatably mount the second rotating roller 230 onto the fixed plate 210.

[0036] Specifically, the output end of the motor 270 is connected to the first rotating shaft 221, the first rotating shaft 221 is fixedly sleeved with the first gear 222, and the second rotating shaft 231 is fixedly sleeved with the second gear 232. The first gear 222 and the second gear 232 mesh with each other. By setting the first gear 222 and the second gear 232 to mesh, when the motor 270 drives the first rotating shaft 221 to rotate, the first rotating shaft 221 drives the first rotating roller 220 and the first gear 222 to rotate. The first gear 222 meshes with and drives the second gear 232 to rotate. The second gear 232 drives the second rotating shaft 231 to rotate. The second rotating shaft 231 drives the second rotating roller 230 to rotate. The first rotating roller 220 and the second rotating roller 230 rotate synchronously in opposite directions, thereby pushing the shock wave guide 240.

[0037] Please see Figure 1 and 4 The present invention also provides an intravascular shockwave therapy device including the above-mentioned catheter pushing mechanism, and a treatment component 300 including a shockwave generator 310 and a connecting cable 320. The connecting cable 320 is electrically connected to the shockwave generator 310. The shockwave catheter 240 is connected to the connecting cable 320. The end of the shockwave catheter 240 is provided with a catheter seat 241, and the catheter seat 241 is connected to the connecting cable 320.

[0038] It should be noted that the motor 270, the shock wave generator 310, and the connecting cable 320 are all conventional instruments. Their working principles, dimensions, and models are not related to the functions of this application, so they will not be described in detail. Their specific models and control principles are existing technologies well known to those in the art, and will not be elaborated here.

[0039] The working principle of the catheter delivery mechanism and intravascular shockwave therapy device is as follows: During use, the shockwave catheter 240 is passed through the fixed ring 120 and the rotating ring 130. After the balloon end of the shockwave catheter 240 is inserted into the blood vessel, the shockwave catheter 240 is placed inside the first rotating roller 220 and the second rotating roller 230. It is used in conjunction with other external medical equipment such as angiography machines. When the motor 270 is started, driving the first rotating shaft 221 to rotate, the first rotating shaft 221 drives the first rotating roller 220 and the first gear 222 to rotate. The first gear 222 meshes with and drives the second gear 232 to rotate. The second gear 232 drives the second rotating shaft 231 to rotate, and the second rotating shaft 231 drives the second rotating roller 230 to rotate. The first rotating roller 220 and the second rotating roller 230 rotate synchronously in opposite directions, thereby pushing the shock wave duct 240. The forward and reverse rotation of the motor 270 is controlled, thus mimicking the forward and backward adjustment when medical personnel push the duct, which greatly improves flexibility and reduces the fatigue of medical personnel. When medical personnel need to rotate the duct, they can slightly turn the handle 132 to drive the rotating ring 130 to rotate, which in turn drives the internal shock wave duct 240 to rotate and adjust before pushing the duct.

[0040] It should be noted that the specific models and specifications of the motor 270, the shock wave generator 310, and the connecting cable 320 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0041] The power supply and operating principle of the motor 270, the shock wave generator 310, and the connecting cable 320 are clear to those skilled in the art and will not be described in detail here.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
