Description

Technical Field

[0001] The invention relates to a medical device for enlarging the inner diameter of a blood vessel at a lesion, in particular to a vibration-type interventional treatment device, belonging to the technical field of medical devices. Background Art

[0002] Percutaneous coronary intervention (PCI) includes percutaneous transluminal coronary angioplasty (PTCA) with or without stents. The main indications are angina pectoris (stable or unstable), myocardial ischemia and acute myocardial infarction. Guidewires and catheters are essential instruments for vascular interventional surgery. Commonly used clinical approaches include femoral artery access, radial artery puncture access, and femoral vein puncture access. Under the guidance of the guidewire and catheter, the patient enters the diseased blood vessel and uses angiography to detect the location, nature and degree of the lesion. Then, surgical operations such as stent implantation, arterial embolization or balloon drug delivery are performed.

[0003] However, in clinical practice, lesions with blood vessels that are too narrow often occur, making it impossible for stents or balloons to reach them smoothly. At present, coronary artery atherectomy and laser interventional therapy are mainly used clinically, and both treatment methods have operational disadvantages. Among them, although coronary artery atherectomy can improve the success rate of opening blood vessels and placing stents, poor operation of coronary artery atherectomy may also cause vascular damage, thrombosis or fragment shedding embolism, and even cause complications such as vascular perforation in severe cases; in addition, coronary artery atherectomy has high requirements for the doctor's operating skills, requiring the doctor to have deep experience accumulation and keen perception of lesions, especially during the operation, the doctor needs to quickly identify and effectively respond to possible complications such as coronary artery spasm, slow blood flow and / or no reflow phenomenon, and vascular dissection. In addition, laser interventional therapy requires precise operation and high technical requirements for doctors. Although the laser has a small penetration depth, it may still cause damage to surrounding tissues; and in some cases, laser interventional therapy is aimed at larger or specially located lesions, and there is a high probability that the lesions cannot be completely removed.

[0004] Therefore, it is necessary to conduct more in-depth research on existing interventional treatment devices to reduce the difficulty of operation for doctors during use and improve the success rate of surgery and patient satisfaction. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems and provide a vibration interventional treatment device.

[0006] The technical solution of the present invention is: a vibration-type interventional treatment device, including a balloon catheter, beaded microspheres, an interventional guidewire, a dynamic pressure sensor, a dynamic torque sensor and an ultrasonic vibration mechanism, wherein the interventional guidewire is inserted into the balloon catheter, and the interventional guidewire is detachably connected to the balloon catheter, and the interventional guidewire outside the human body is sequentially installed with the dynamic pressure sensor and the dynamic torque sensor, and is characterized in that: the balloon catheter is placed in a vascular calcification lesion in the human body, the balloon catheter is opened by filling with water so that its outer wall is in close contact with the vascular wall at the vascular calcification lesion, an interventional guidewire with a plurality of beaded microspheres arranged at the front end is inserted into the balloon catheter or the interventional guidewire is directly inserted, the plurality of beaded microspheres arranged on the interventional guidewire or the front end of the interventional guidewire reaches the vascular calcification lesion, and after the stenosis and occlusion at the vascular calcification lesion are relieved, the interventional guidewire and the balloon catheter can be withdrawn synchronously along the original route of the vascular wall, or after the interventional guidewire is withdrawn from the inside of the balloon catheter, the interventional guidewire is first withdrawn along the original route of the vascular wall, and then the balloon catheter is withdrawn.

[0007] The present invention also includes an ultrasonic vibration mechanism, which includes a longitudinal vibration piezoelectric ceramic group for controlling the front end of the interventional guide wire to produce telescopic vibration and a torsional vibration piezoelectric ceramic group for controlling the front end of the interventional guide wire to produce torsional vibration. The ultrasonic vibration mechanism produces telescopic vibration and torsional vibration that act together on the rear end of the interventional guide wire.

[0008] Furthermore, in the above-mentioned vibration interventional treatment device, a developing material for positioning under CT is added to the front end of the interventional guide wire, and the developing material includes one of polyurethane material, barium sulfate, bismuth compound and tungsten.

[0009] Preferably, the diameters of the beaded microspheres are arranged gradually from the front end of the interventional guidewire, and are all fixed to the interventional guidewire. The maximum diameter of the beaded microspheres is smaller than the inner diameter of the balloon catheter, and developing materials for positioning under CT are added to the surface of the beaded microspheres.

[0010] Furthermore, the above-mentioned vibration-type interventional treatment instrument, wherein: the ultrasonic vibration mechanism also includes an ultrasonic amplitude transformer, a first block, a second block, a third block and a fastener, the first end of the ultrasonic amplitude transformer is fixedly connected to the rear end of the interventional guidewire, and the second end of the ultrasonic amplitude transformer is fixedly connected to the first end of the first block. The longitudinal vibration piezoelectric ceramic group is fixedly arranged between the second end of the first block and the first end of the second block, and the torsional vibration piezoelectric ceramic group is fixedly arranged between the second end of the second block and the first end of the third block. The fastener sequentially penetrates and fixes the third block, the torsional vibration piezoelectric ceramic group, the second block, the longitudinal vibration piezoelectric ceramic group and the first block to form the ultrasonic vibration mechanism as a whole.

[0011] Furthermore, in the above-mentioned vibration interventional treatment instrument, the longitudinal vibration piezoelectric ceramic group includes several pieces of longitudinal vibration piezoelectric ceramics polarized along the thickness direction, and each piece of longitudinal vibration piezoelectric ceramics is equidistantly arranged along the axial direction.

[0012] Furthermore, in the above-mentioned vibration interventional treatment instrument, the torsional vibration piezoelectric ceramic group includes several pieces of tangentially polarized torsional vibration piezoelectric ceramics, and each piece of torsional vibration piezoelectric ceramic is equidistantly arranged along the axial direction.

[0013] In this way, by adopting the technical solution of the present invention, the ultrasonic vibration mechanism is intelligently controlled by the vibration drive control system. The vibration drive control system can collect the real-time changing data of the dynamic pressure sensor and the dynamic torque sensor, and can monitor the output power of the ultrasonic vibration mechanism in real time. According to the real-time change of the power, the force at the vascular calcification lesion is converted and fed back to the vibration drive control system. The driving voltage, phase and amplitude of the longitudinal vibration piezoelectric ceramic group and the torsional vibration piezoelectric ceramic group are controlled by the vibration drive control system to accurately control the amplitude of the front end of the interventional guide wire or several bead-shaped microspheres set at the front end of the interventional guide wire. The bead-shaped microspheres set at the front end of the interventional guide wire can provide directional vibration of specified frequency and power, and can independently adjust the vibration amplitude of the telescopic vibration and torsional vibration, adjust the penetration force and linear motion speed under dynamic conditions, so that it can accurately penetrate the plaque at the vascular calcification lesion, and avoid excessive amplitude after penetration to damage the inner wall of the blood vessel.

[0014] Compared with the prior art, after adopting the technical solution of the present invention, two vibration forms, namely, a longitudinal vibration piezoelectric ceramic group and a torsional vibration piezoelectric ceramic group, are provided. The force feedback signal of the vibration of the interventional guidewire can be collected in real time via the dynamic pressure sensor and the dynamic torque sensor. Then, the longitudinal vibration piezoelectric ceramic group and the torsional vibration piezoelectric ceramic group are combined to accurately control the size, phase and amplitude of the driving voltage according to the feedback signal. Under the condition of ensuring safe operation, the calcified and stenotic lesions can be gradually and point-to-point destroyed, the surgical accuracy can be improved, and the complications of the existing atherectomy technology or laser technology, such as vascular injury, thrombosis, fragment shedding and embolism, and lesions can be effectively avoided. The invention can solve the problems of incomplete removal and the like; moreover, several beaded microspheres can be arranged at the front end of the interventional guidewire, and the interventional guidewire forming a beaded structure can be matched with the balloon catheter. Different types of longitudinal vibration piezoelectric ceramic groups and torsional vibration piezoelectric ceramic groups are used to excite the rear end of the interventional guidewire, thereby transmitting the vibration force to generate telescopic vibration and torsional vibration at the front end of the interventional guidewire in the blood vessel. The two vibrations under the synergistic effect are transmitted through the close contact between the balloon catheter and the calcified lesions of the blood vessels, thereby more efficiently destroying the stenotic lesions in the blood vessels, and finally allowing the interventional surgical instruments to pass through and reach the designated position, which helps to improve the efficiency and success rate of the operation.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings to make it easier to understand and grasp. The balloon catheter 1, interventional guidewire 4, dynamic pressure sensor 5 and dynamic torque sensor 6 involved therein are all commonly used by ordinary technicians in the field, and there is no special requirement for them in this case.

[0020] like Figure 1 As shown, a vibration-type interventional treatment device of the present embodiment includes a balloon catheter 1, beaded microspheres 3, an interventional guidewire 4, a dynamic pressure sensor 5, a dynamic torque sensor 6 and an ultrasonic vibration mechanism. The interventional guidewire 4 is inserted into the balloon catheter 1, and the interventional guidewire 4 is detachably connected to the balloon catheter 1. The dynamic pressure sensor 5 and the dynamic torque sensor 6 are sequentially installed on the interventional guidewire 4 outside the human body.

[0021] According to the technical solution of this embodiment: the balloon catheter 1 is placed in the vascular calcification lesion 2 in the human body, and the balloon catheter 1 is opened by filling with water (the operation of filling with water facilitates ultrasound to penetrate the mixed interface of gas and liquid, and improves the vibration transmission effect) so that its outer wall is in close contact with the vascular wall of the vascular calcification lesion 2, and an interventional guide wire 4 with a plurality of beaded microspheres 3 set at the front end is inserted into the balloon catheter 1 or the interventional guide wire 4 is directly inserted (when the vascular calcification lesion 2 is too narrow, the number of beaded microspheres 3 can be 0), and a part of the plurality of beaded microspheres 3 set on the interventional guide wire 4 or the front end of the interventional guide wire 4 reaches the vascular calcification lesion 2 After relieving the stenosis and occlusion of the vascular calcification lesion 2, the interventional guidewire 4 and the balloon catheter 1 can be withdrawn synchronously along the original route of the blood vessel wall, or after the interventional guidewire 4 is pulled out from the inside of the balloon catheter 1, the interventional guidewire 4 is first withdrawn along the original route of the blood vessel wall, and then the balloon catheter 1 is withdrawn; it also includes an ultrasonic vibration mechanism, the ultrasonic vibration mechanism includes a longitudinal vibration piezoelectric ceramic group 12 for controlling the front end of the interventional guidewire 4 to generate telescopic vibration and a torsional vibration piezoelectric ceramic group 13 for controlling the front end of the interventional guidewire 4 to generate torsional vibration, and the telescopic vibration and torsional vibration generated by the ultrasonic vibration mechanism act together on the rear end of the interventional guidewire 4.

[0022] Preferably, in the above structure: a developing material for positioning under CT is added to the front end of the interventional guide wire 4, and the developing material includes one of polyurethane material, barium sulfate, bismuth compound and tungsten. When the number of bead-shaped microspheres 3 is 0, CT is used to locate whether the front end of the interventional guide wire 4 reaches the position of the vascular calcification lesion 2, and the real-time force feedback data of the dynamic pressure sensor 5 and the dynamic torque sensor 6 at this time are measured.

[0023] Preferably, in the above structure: the diameters of the beaded microspheres 3 are arranged from small to large starting from the front end of the interventional guide wire 4, and they are all fixedly connected to the interventional guide wire 4. The beaded microspheres 3 arranged in a continuous bead shape are convenient for generating adjustable directional vibrations, and the maximum diameter of the beaded microspheres 3 is smaller than the inner diameter of the balloon catheter 1. Development materials for positioning under CT are added on the surfaces of the beaded microspheres 3. CT is used to locate whether the front end of the interventional guide wire 4 or the set beaded microspheres 3 reaches the position of the vascular calcification lesion 2, and the real-time force feedback data of the dynamic pressure sensor 5 and the dynamic torque sensor 6 are measured at this time.

[0024] Preferably, in the above structure: the ultrasonic vibration mechanism also includes an ultrasonic amplitude transformer 7, a first block 8, a second block 9, a third block 10, and a fastener 11 (i.e., a bolt). The size and dimensions of the ultrasonic amplitude transformer 7 can be selected according to the specific blockage situation after angiography. The ratio of the left end diameter to the right end diameter is between 0.2-0.8. Different diameter ratios correspond to different left end amplitudes, which leads to different amplitudes at the end of the catheter. The purpose is to provide forward vibrations suitable for destroying plaques, while the vibration is not too large, thereby avoiding vascular damage.

[0025] Specifically, in the above-mentioned ultrasonic vibration mechanism, the first end of the ultrasonic horn 7 is fixedly connected to the rear end of the interventional guide wire 4, and the second end of the ultrasonic horn 7 is fixedly connected to the first end of the first stopper 8. The first stopper 8 is a wedge-shaped stopper structure, and the tip of the wedge-shaped stopper structure is defined as the first end of the first stopper 8, and the wide end of the wedge-shaped stopper structure is the second end of the first stopper 8, so as to better transmit the vibration force to the ultrasonic horn 7; the second stopper 9 and the third stopper 10 are both cubic structures, and the integrity of the ultrasonic vibration mechanism is maintained by the action between the various stoppers. The longitudinal vibration piezoelectric ceramic group 12 is fixedly provided between the second end of the first stopper 8 and the first end of the second stopper 9, and the torsional vibration piezoelectric ceramic group 13 is fixedly provided between the second end of the second stopper 9 and the first end of the third stopper 10. Finally, the third stopper 10, the torsional vibration piezoelectric ceramic group 13, the second stopper 9, the longitudinal vibration piezoelectric ceramic group 12 and the first stopper 8 are sequentially connected and fixed by the fastener 11 (i.e., a bolt) to form the entire ultrasonic vibration mechanism.

[0026] Preferably, if Figure 2 As shown in the above structure: the longitudinal vibration piezoelectric ceramic group 12 includes four pieces polarized along the thickness direction (such as Figure 2 The longitudinal vibration piezoelectric ceramics 121 are arranged equidistantly along the axial direction. The longitudinal vibration piezoelectric ceramics 121 are placed in a strong DC electric field. Figure 2 Here, sinωt represents a sine wave with a frequency of ω, which is a process of orienting the electric domains along the direction of the electric field. After polarization treatment, the longitudinal vibration piezoelectric ceramic 121 has piezoelectric properties. Through the matching design of the polarization direction and the applied electric field, it can generate longitudinal vibration, and the number of longitudinal vibration piezoelectric ceramics 121 can be increased or decreased by power design.

[0027] Specifically, the left and right sides of the adjacent longitudinal vibration piezoelectric ceramics 121 are both provided with first electrode sheets 122 for continuous power supply, which have a certain anti-interference ability and improve stability and precision.

[0028] Preferably, if Figure 3 As shown in the above structure: the torsional vibration piezoelectric ceramic group 13 includes two tangentially polarized (such as Figure 3 The torsional vibration piezoelectric ceramics 131 are arranged equidistantly along the axial direction. The torsional vibration piezoelectric ceramics 131 are placed in a strong DC electric field. Figure 3Here, sin(ωt+φ) represents a sine wave with a frequency of ω, and the phase shift φ represents the starting position of the waveform on the time axis or the offset relative to the reference position, which is the process of orienting the electric domains along the direction of the electric field. After polarization treatment, the torsional piezoelectric ceramic 131 has piezoelectric properties, and through the matching design of the polarization direction and the applied electric field, it generates torsional vibration, wherein the number of torsional piezoelectric ceramics 131 can be increased or decreased by power design.

[0029] Specifically, the second electrode sheets 132 are disposed on both the left and right sides of the adjacent torsional piezoelectric ceramics 131 . The second electrode sheets 132 have a certain anti-interference capability, thereby improving stability and precision.

[0030] In the technical solution of the present invention, a plurality of bead-shaped microspheres 3 are attached to the interventional guide wire 4, and a vibration driving structure is provided in which a longitudinal vibration piezoelectric ceramic group 12 and a torsional vibration piezoelectric ceramic group 13 cooperate with each other. The combination of these two aspects is the technical key of this case. Figure 1 The specific structure of the beaded microspheres 3 fixedly connected to the interventional guide wire 4 is shown. The beaded microspheres 3 can provide directional vibrations of a specified frequency and power, so that the front end of the interventional guide wire 4 can perform axial extension and retraction operations, thereby generating vibrations; Figure 2 and Figure 3 The key parts displayed are the longitudinal vibration piezoelectric ceramic group 12 and the torsional vibration piezoelectric ceramic group 13. For the dynamic pressure sensor 5 and the dynamic torque sensor 6, the dynamic pressure sensor 5 can adopt a piezoelectric pressure sensor; the sensitivity of the dynamic torque sensor 6 is 1±0.2mv / V; the torque is measured by strain gauge electrical measurement technology, and a strain bridge is formed on the elastic shaft. The electrical signal of the elastic shaft being torsion can be measured by providing power to the strain bridge. After the strain signal is amplified, it is converted into a frequency signal proportional to the torsion through pressure and / or frequency conversion. Ordinary technicians in this field can make conventional settings according to the existing technology, and this case has no special requirements for its model selection and combined use.

[0031] In this way, by adopting the technical solution of the present invention, the ultrasonic vibration mechanism is intelligently controlled by a vibration drive control system (a vibration monitoring system may be used, for example, a KM vibration online monitoring system, etc.), and the vibration drive control system can collect real-time changing data of the dynamic pressure sensor 5 and the dynamic torque sensor 6 to monitor the output power of the ultrasonic vibration mechanism in real time, calculate the force at the vascular calcification lesion 2 according to the real-time change of the power, and feed it back to the vibration drive control system, and control the driving voltage of the longitudinal vibration piezoelectric ceramic group 12 and the torsional vibration piezoelectric ceramic group 13 through the vibration drive control system. The phase and amplitude are transmitted by the ultrasonic amplitude transformer 7 to the front end of the interventional guidewire 4 or the several beaded microspheres 3 set at the front end of the interventional guidewire 4, so as to accurately control the amplitude of the front end of the interventional guidewire 4 or the several beaded microspheres 3 set at the front end of the interventional guidewire 4. The beaded microspheres 3 set at the front end of the interventional guidewire 4 can provide directional vibration of specified frequency and power, and can independently adjust the vibration amplitude of the telescopic vibration and the torsional vibration, and adjust the penetration force and the linear motion speed under dynamic conditions, so that it can accurately penetrate the plaque of the vascular calcification lesion 2, and at the same time avoid excessive amplitude after penetration to damage the inner wall of the blood vessel. When the force feedback signal changes from weak to strong, it indicates that the interventional guidewire 4 is destroying the calcified lesions. If a sudden drop in force is detected, it indicates that the calcified tissue has been destroyed. At the same time, you can try to push the interventional guidewire 4 in a straight line outside the body. If the force feedback signal gradually increases at this time, continue to adjust the driving voltage value of the longitudinal vibration piezoelectric ceramic group 12 and / or the torsional vibration piezoelectric ceramic group 13 until the force feedback information becomes weak again. The cycle is repeated until the interventional guidewire 4 reaches the narrow vascular calcified lesion 2, and the balloon catheter 1 is placed at the vascular calcified lesion 2 to expand the inner diameter of the blood vessel so that the interventional surgical instrument can pass through.

[0032] Through the above description, it can be found that compared with the prior art, after adopting the technical solution of the present invention, two vibration forms, namely, a longitudinal vibration piezoelectric ceramic group and a torsional vibration piezoelectric ceramic group, are provided. The force feedback signal of the vibration of the interventional guidewire can be collected in real time via a dynamic pressure sensor and a dynamic torque sensor. Then, the longitudinal vibration piezoelectric ceramic group and the torsional vibration piezoelectric ceramic group are combined to accurately control the size, phase and amplitude of the driving voltage according to the feedback signal. Under the condition of ensuring safe operation, the calcified stenosis lesions can be gradually and point-to-point destroyed, the surgical accuracy can be improved, and the complications of the existing atherectomy technology or laser technology, such as vascular damage, thrombosis, and fragment shedding embolism, can be effectively avoided. , and incomplete lesion removal; moreover, several beaded microspheres can be set at the front end of the interventional guidewire, and the interventional guidewire forming a beaded structure can be matched with the balloon catheter. Different types of longitudinal vibration piezoelectric ceramic groups and torsional vibration piezoelectric ceramic groups are used to excite the rear end of the interventional guidewire, thereby transmitting vibration force to generate telescopic vibration and torsional vibration at the front end of the interventional guidewire in the blood vessel. The two vibrations under the synergistic effect are transmitted through the balloon catheter in close contact with the calcified lesions of the blood vessels, thereby more efficiently destroying the stenotic lesions in the blood vessels, and finally allowing the interventional surgical instruments to pass through and reach the designated position, which helps to improve the efficiency and success rate of the operation.

[0033] The technical scheme, working process and implementation effect of the present invention are described in detail above. It should be noted that what is described is only a typical example of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical scheme formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
