Description

Technical Field

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

[0002] Intravascular balloon shockwave lithotripsy equipment can generally be divided into three parts according to function: the main unit, the handle, and the balloon catheter. The main unit is a high-voltage pulse generator, and the handle is a high-voltage pulse channel and control input interface. By adding one or more electrodes that can generate shock waves (also known as shock waves) inside the balloon of the catheter, and connecting the balloon catheter to the handle and the main unit, shock waves can be released simultaneously or sequentially by one or more electrodes under the control of the main unit.

[0003] During vascular shockwave therapy surgery, the main unit of the treatment device is placed on a cabinet, and then the handle is connected to the balloon and the main unit to use the shockwave therapy device. However, the shockwave therapy device is placed on the cabinet and lacks a fixing structure, which easily leads to the risk of the shockwave therapy device falling. To address this, we propose a positioning device and an intravascular shockwave therapy device. Utility Model Content

[0004] To overcome the shortcomings of the existing devices, this application provides a positioning device and an intravascular shockwave therapy device, which can solve the problem of the shockwave therapy device being easily dropped during use.

[0005] In the first aspect, the technical solution adopted by the embodiments of this application to solve its technical problem is: a positioning device, including a movable box, a rotating shaft rotatably connected to the top of the movable box, a support platform installed on the top of the rotating shaft, a clamping mechanism for fixing a shock wave therapy device installed on the support platform, a fixing ring also installed on the top of the movable box, and a plurality of snap-fit ​​parts installed on the outer wall of the rotating shaft, wherein the plurality of snap-fit ​​parts are snap-fitted with the fixing ring.

[0006] In one specific implementation, the clamping mechanism includes a positioning block fixedly installed on the top of the support platform. The positioning block has a positioning groove, and a double-ended screw is rotatably connected between the two side walls of the positioning groove. Two positioning elements are threaded onto the double-ended screw.

[0007] In one specific implementation, the positioning component includes two sliders, which are slidably disposed in the positioning groove and threaded onto the double-ended screw. One end of each slider is fixedly connected to a clamping block.

[0008] In one specific implementation, a plurality of grooves are provided on the side wall of the rotating shaft, and a plurality of snap-fit ​​components are respectively disposed in the plurality of grooves, and a plurality of arc-shaped holes are provided on the inner wall of the fixing ring.

[0009] In one specific implementation, the snap-fit ​​component includes a plug rod that is slidably disposed within the groove. One end of the plug rod is connected to the groove by a spring, and the other end of the plug rod is arc-shaped. The arc-shaped end of the plug rod is inserted into one of the arc-shaped holes.

[0010] In one specific implementation, a support ring is fixedly installed on the top of the mobile housing, and an annular groove is formed on the top of the support ring. Several support wheels are installed in the annular groove, and the support platform is placed on the several support wheels.

[0011] In one specific implementation, a number of rollers are fixedly installed at the bottom of the mobile housing.

[0012] Secondly, this application also provides an intravascular shockwave therapy device, including the aforementioned positioning device.

[0013] The advantages of this embodiment are as follows: By rotating a shaft at the top of the movable housing, installing a support platform at the top of the shaft, and installing a clamping mechanism on the support platform, the shockwave therapy device is placed on the support platform and clamped and fixed by the clamping mechanism, thus achieving the purpose of positioning the shockwave therapy device. By installing a fixing ring at the top of the movable housing, with several arc-shaped holes on the inner wall of the fixing ring, and a groove on the outer wall of the shaft, a rod is slidably arranged in the groove, and a spring is connected between one end of the rod and the groove, so that the arc-shaped end of the rod can be inserted into the arc-shaped hole, thus achieving the positioning of the shaft. When the support platform is rotated, the end of the rod can switch between several arc-shaped holes, thereby facilitating the adjustment of the angle of the shockwave therapy device.

Detailed Implementation

[0020] The technical solution in this application embodiment is to solve the problem of the shockwave therapy device being easily dropped during use. The overall idea is as follows:

[0021] Example:

[0022] Please see Figure 1-5 A positioning device includes a movable housing 10, a rotating shaft 20 rotatably connected to the top of the movable housing 10, a support platform 30 mounted on the top of the rotating shaft 20, a clamping mechanism 40 for fixing a shockwave therapy device mounted on the support platform 30, a fixing ring 50 also mounted on the top of the movable housing 10, and a plurality of snap-fit ​​pieces 60 mounted on the outer wall of the rotating shaft 20, which are snap-fitted with the fixing ring 50. Specifically, the intravascular shockwave therapy device is placed on the support platform 30 and clamped and fixed by the clamping mechanism 40 to prevent the shockwave therapy device from moving. The support platform 30 is mounted on the rotating shaft 20, and the snap-fit ​​pieces 60 mounted on the rotating shaft 20 and snap-fitted with the fixing ring 50 facilitate the rotation of the support platform 30, thereby facilitating the adjustment of the angle of the shockwave therapy device. Furthermore, a plurality of rollers 80 are fixedly mounted on the bottom of the movable housing 10, specifically consisting of directional wheels and universal wheels.

[0023] See Figure 2 and 3The clamping mechanism 40 includes a positioning block 410 fixedly installed on the top of the support platform 30. A positioning groove 420 is provided on the positioning block 410. A double-ended screw 430 is rotatably connected between the two end sidewalls of the positioning groove 420. Two positioning elements 440 are threaded onto the double-ended screw 430. Each positioning element 440 includes two sliders 4410, which are slidably disposed within the positioning groove 420 and threaded onto the double-ended screw 430. A clamping block 4420 is fixedly connected to one end of each slider 4410. During setup, the two sliders 4410... Both ends are provided with internal threaded holes, so that the double-ended screw 430 can drive the two sliders 4410 to slide in the positioning groove 420. The two clamping blocks 4420 are slidably mounted on the support platform 30. The two sliders 4410 drive the two clamping blocks 4420 to move on the support platform 30. At the same time, buffer pads are provided on the facing surfaces of the two clamping blocks 4420. Furthermore, one end of the double-ended screw 430 rotates through one end of the side wall of the positioning groove 420. Specifically, the cylindrical part of the double-ended screw 430 rotates the side wall of the positioning groove 420, and one end of it is connected to a handle.

[0024] See Figure 5 The side wall of the rotating shaft 20 has several grooves 210, and several snap-fit ​​pieces 60 are respectively disposed in the grooves 210. The inner wall of the fixing ring 50 has several arc-shaped holes 510. The snap-fit ​​piece 60 includes a rod 610, which is slidably disposed in the groove 210. A spring 620 is connected between one end of the rod 610 and the groove 210, and the other end of the rod 610 is arc-shaped. The arc-shaped end of the rod 610 is inserted into one of the arc-shaped holes 510. In the specific setup, when the rotating shaft 20 rotates, it will cause the arc-shaped end of the insertion rod 610 to slide within the arc-shaped hole 510. The arc-shaped end of the insertion rod 610 will be squeezed by the arc-shaped hole 510, thereby causing the insertion rod 610 to slide into the groove 210. At the same time, it will squeeze the spring 620, thereby causing the end of the insertion rod 610 to travel into the next arc-shaped hole 510 to complete the angle adjustment of the support platform 30, and thus complete the adjustment of the shock wave therapy equipment, so as to facilitate the use of the shock wave therapy equipment.

[0025] See Figure 4 A support ring 70 is fixedly installed on the top of the movable housing 10. An annular groove 710 is opened on the top of the support ring 70. Several support wheels 720 are installed in the annular groove 710. The support platform 30 is placed on the several support wheels 720. Specifically, a connecting shaft is fixedly connected to both ends of the support wheel 720. The connecting shaft is rotatably connected to the inner wall of the annular groove 710. The several support wheels 720 support the support platform 30, which can reduce the frictional resistance on the support platform 30.

[0026] An intravascular shockwave therapy device, comprising

[0027] The aforementioned positioning device.

[0028] When using this application: the shockwave therapy device is placed on the support platform 30, and then the double-ended screw 430 is rotated. The double-ended screw 430 drives the two sliders 4410 to move towards each other, thereby causing the two clamping blocks 4420 to move towards each other, so as to clamp and fix the shockwave therapy device on the support platform 30, thereby positioning the shockwave therapy device. When it is necessary to adjust the angle of the shockwave therapy device, the support platform 30 is pushed to rotate, so as to adjust the angle of the shockwave therapy device for easy use.

[0029] It should be noted that the specific model and specifications of the mobile housing 10 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0030] The power supply and its principle for the movable housing 10 are clear to those skilled in the art and will not be described in detail here.

[0031] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
