Description

Technical Field

[0001] This utility model relates to the field of balloon polishing technology, specifically to an automatic balloon tube segment polishing device. Background Technology

[0002] A high-pressure balloon is a specialized instrument used in interventional medical procedures. Typically made of high-strength polymer materials, it possesses excellent pressure resistance and expandability while maintaining precise diameter and shape. It is suitable for the pretreatment of severely calcified lesions, and the balloon surface is coated with medication to inhibit restenosis. It is widely used in cardiovascular, urological, and digestive fields.

[0003] Because high-pressure balloons use thicker tubing, the outer diameter of the balloon catheter increases, making it difficult to pass through narrowed lesions. Without changing the original material of the balloon catheter, it is impossible to simultaneously meet the dual requirements of high pressure resistance and good passage. Therefore, the balloon tubing segment needs to be ground to reduce its outer diameter. Current technology typically involves manual operation by employees, which is inefficient and results in poor consistency in balloon dimensions. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] like Figures 1-7 As shown, in one embodiment, an automatic grinding device for balloon tubing segments includes:

[0033] (1) The control host 1, as the core control unit of the entire automatic grinding equipment, is firmly installed on one side of the workbench 2. It integrates a variety of control modules and circuit components, and can receive various instructions input by the operator, thereby realizing the precise setting of key parameters in the grinding process. These parameters cover grinding speed, grinding time, rotation angle, etc., providing basic control logic for the automated operation of the entire grinding process.

[0034] (2) Drive motor 3 is installed inside the control host 1. As a power output source, it can efficiently convert electrical energy into mechanical energy. According to the preset speed and direction of the control host 1, it stably drives the balloon catheter to rotate, thereby cooperating with the grinding parts to complete the grinding operation of the balloon tube section.

[0035] (3) Pneumatic chuck 4 is rotatably connected to drive motor 3 and clamps and releases the balloon catheter assembly through the connected air source, ensuring that the balloon catheter assembly will not be displaced or fall off during the polishing process, thus ensuring the accuracy of polishing.

[0036] (4) Clamping fixture 5 is set on the other side of the worktable 2 to clamp the grinding parts (such as sandpaper) so that the grinding parts and the rotating balloon catheter assembly maintain a suitable relative position relationship so that the grinding parts can uniformly and effectively grind the balloon tube segment during the rotation of the balloon catheter.

[0037] Please continue reading. Figures 1-7 In this embodiment, a display slot 11 matching the size of the display is specially provided on the front or operation panel of the control host 1. This slot can accommodate the installation requirements of the touch display. After the display is embedded in the slot, not only can the stability of the display installation be guaranteed, but also the operator can conveniently and clearly observe the various information displayed on the display during operation.

[0038] Furthermore, on one side of the display slot 11, multiple sets of reserved holes 12 are provided according to a certain layout and spacing. The size and number of these reserved holes 12 are set according to the type of display control components and installation requirements. They can be used to install various display control components (such as operation buttons, indicator lights, adjustment knobs, etc.), thereby enriching the operation functions and information display methods of the control host 1.

[0039] It should be explained in detail that the control host 1 is also equipped with a control motherboard 13, which can carry a variety of chips, circuit interfaces and control programs. It can receive signals from various sensors and operating components, and after calculation and processing, send corresponding control signals to various actuators such as drive motor 3, pneumatic chuck 4, clamping fixture 5, etc., to coordinate the actions between the components and ensure that the equipment operates stably according to the preset process.

[0040] For example, the pneumatic clamp 4 is detachably mounted on the rotating shaft block 6, which facilitates the replacement, repair and maintenance of the pneumatic clamp 4. When it is necessary to adapt to balloon catheter assemblies of different specifications, the corresponding pneumatic clamp 4 can be quickly replaced. The pneumatic clamp 4 is rotatably connected to the bearing seat 7 through the rotating shaft block 6, so that the pneumatic clamp 4 can rotate flexibly around the bearing seat 7 together with the rotating shaft block 6 under the drive of the drive motor 3, ensuring the smooth rotation of the balloon catheter assembly.

[0041] Furthermore, a diaphragm coupling 8 is detachably installed at the output end of the drive motor 3, which can effectively transmit the torque of the drive motor 3; the drive motor 3 is rotatably connected to the rotating shaft of the pneumatic chuck 4 through the diaphragm coupling 8, and the rotational power generated by the drive motor 3 can be transmitted to the rotating shaft of the pneumatic chuck 4 through the diaphragm coupling 8, thereby driving the pneumatic chuck 4 and the held balloon catheter assembly to rotate; while achieving high-efficiency transmission, it can also compensate for certain installation errors and axial, radial and angular offsets during operation, ensuring the stability of transmission.

[0042] It should be explained in detail that the pneumatic chuck 4 includes grippers 41, and multiple sets of grippers 41 are arranged at equal angles around the connecting block 42, so that the gripping force of the grippers 41 on the balloon catheter assembly is more uniform, avoiding deformation or damage to the balloon catheter assembly due to uneven gripping force, while ensuring the coaxiality of the balloon catheter assembly during rotation.

[0043] Specifically, the connecting block 42 is detachably mounted on the cover plate 43 so that the type and layout of the gripper 41 can be adjusted according to different balloon catheter assembly specifications; while the cover plate 43 is detachably connected to the rotating shaft block 6, further improving the disassembly and assembly flexibility of the overall structure of the pneumatic chuck 4, facilitating equipment maintenance and component replacement.

[0044] Please continue reading. Figures 1-7 In this embodiment, the clamping fixture 5 includes a clamping block 51. A special clamping groove 511 is provided on the top of the clamping block 51 according to the shape and size of the grinding part. The shape of the clamping groove 511 is adapted to the grinding part (such as sandpaper), which can stably embed the grinding part therein, prevent the grinding part from sliding or falling off during the grinding process, and ensure the smooth progress of the grinding operation.

[0045] Furthermore, a lead screw guide module 9 is installed at the bottom of the clamping block 51. The lead screw guide module 9 can drive the clamping block 51 to achieve linear displacement adjustment along the axial direction of the balloon catheter under the action of manual or external drive device, thereby adjusting the distance between the grinding part and the balloon catheter assembly. A linear guide module 10 is installed below the lead screw guide module 9, which can drive the clamping block 51 to achieve linear displacement adjustment along the radial direction of the balloon catheter under the action of manual or external drive device, thereby adjusting the relative position between the grinding part and the balloon catheter assembly.

[0046] Working principle: Select the matching pneumatic chuck 4 and mandrel according to the size of the balloon product. Install the balloon to be processed on the pneumatic chuck 4. Adjust the polishing process parameters (such as polishing speed, polishing time, etc.) through the touch screen on the control host 1. After the polishing process is started, the control motherboard 13 controls the drive system to drive the pneumatic chuck 4 and balloon tubing to rotate. The lead screw guide module 9 and linear guide module 10 move accordingly, driving the sandpaper fixed on the clamping block 51 to move accordingly. That is, by adjusting the relative movement between the rotating balloon and the moving sandpaper, the automatic polishing of the balloon tubing section is achieved, ultimately reducing the outer diameter of the balloon tubing section, improving polishing efficiency and dimensional consistency.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
