Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing equipment technology, specifically to a tooling for bonding balloon guide tubes to balloons. Background Technology

[0002] Balloon guiding catheters are commonly used medical devices in interventional therapy. They typically consist of a multi-layered composite catheter with an outer layer that has a certain degree of hardness and wear resistance and an inner layer that is smooth, as well as an expandable balloon. They are mainly used to deliver the balloon to specific parts of the body, such as blood vessels, to assist in treatment. Balloon guiding catheter bonding involves surface treatment of the area where the balloon and guiding catheter need to be bonded, so that the balloon is firmly fixed to the guiding catheter, ensuring that the entire device can function properly during treatment.

[0003] Existing technologies often have the following problems when used:

[0004] In the manufacturing process of balloon guiding catheters, the bonding between the balloon and the guiding catheter is a critical step. Traditional bonding methods often rely on manual operation, which makes it difficult to guarantee the bonding and positioning accuracy between the balloon and the guiding catheter, easily affecting the performance of the balloon guiding catheter. Furthermore, the balloon's edge-flipping and repositioning operation after applying adhesive is inefficient, and the applied adhesive tends to solidify prematurely, resulting in poor bonding between the balloon and the guiding catheter. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tooling for bonding balloons to balloon guide tubes. It can effectively solve the problems in the existing technology that it is difficult to ensure the bonding and positioning accuracy of balloons and guide tubes by manual operation, which can easily affect the performance of balloon guide tubes. It also solves the problems that the balloon and guide tube have low efficiency in the balloon flipping and resetting operation after applying glue, resulting in poor bonding effect between balloons and guide tubes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a tooling for bonding a balloon guide tube to a balloon, comprising:

[0008] The guide tube and the balloon, wherein the guide tube has several air holes on its circumferential sidewall;

[0009] The positioning base frame has a semi-circular upper surface.

[0010] A balloon positioning assembly includes two sets of lifting slide rods fixedly connected to the upper end face of a positioning base. Positioning pressure plates are slidably connected to the outer peripheral walls of the two sets of lifting slide rods. A lifting adjustment plate is fixedly connected between the two positioning pressure plates. A support frame is fixedly connected to the upper end face of the positioning base. A positioning drive component is fixedly connected to the middle of the support frame. The positioning drive component is used to drive the lifting adjustment plate and the two positioning pressure plates to move up and down.

[0011] Two auxiliary bonding components are fixedly connected to the upper end of the support frame. The auxiliary bonding components are used to assist in completing the flanging and repositioning operation after the balloon is coated with glue.

[0012] Furthermore, the positioning drive component includes a threaded sleeve fixedly connected to the middle of the upper end of the support frame, and an adjusting screw is threadedly connected inside the threaded sleeve. The lower end of the adjusting screw is rotatably connected to the upper surface of the lifting adjustment plate.

[0013] Furthermore, the auxiliary bonding component includes a sliding frame fixedly connected to the upper end of the support frame, a limiting slider slidably connected to the sliding frame, a straight rod slidably connected through the middle of the limiting slider, a convex block fixedly connected to the lower end of the straight rod, and a flap fixedly connected to the lower end of the convex block.

[0014] Furthermore, the auxiliary bonding component also includes a first micro magnet fixedly connected to the upper end face of the convex block, and a second micro magnet fixedly connected to the lower end face of the limiting slider. The first micro magnet and the second micro magnet are arranged with opposite poles attracting each other.

[0015] Furthermore, thin silicone pads are provided on the upper end face of the positioning base and the lower end face of the positioning pressure plate.

[0016] Furthermore, an adjustment knob is fixedly connected to the upper end of the adjustment screw, and several anti-slip protrusions are fixedly connected to the outer peripheral wall of the adjustment knob. A traction ring is fixedly connected to the upper end of the straight rod.

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] This invention includes a balloon positioning assembly. By turning the adjusting screw, the lifting adjustment plate and two positioning pressure plates are driven to move downward. Several lifting slide rods can limit the downward movement of the two positioning pressure plates to maintain their downward stability. When the two positioning pressure plates move down to contact the positioning base and the balloon, the balloon and guide tube can be precisely positioned on both sides, ensuring the stability and bonding accuracy of the balloon during subsequent bonding, and guaranteeing the performance of the balloon guide tube.

[0019] This invention includes an auxiliary bonding component. After the balloon is positioned, the convex block can be pushed down to ensure that the flap is fully attached to the balloon. When the balloon is flapped and glue is applied to the balloon and guide tube, the flap of the balloon covers the flap. After the glue is applied, the convex block is quickly driven to move up and slide horizontally, causing the flap of the balloon to begin to separate from the guide tube. This allows the operator to quickly reset the flap of the balloon, improving the efficiency of the balloon flap reset operation, preventing the applied glue from solidifying, and ensuring the bonding effect between the balloon and the guide tube.

[0027] 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. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example: Refer to Figures 1 to 5 A tooling for bonding a balloon guide tube to a balloon includes: a guide tube 1, a balloon 2, a positioning base 4, and a balloon positioning assembly. The guide tube 1 has several air holes 3 on its circumferential sidewalls. The upper end face of the positioning base 4 has a semi-circular structure. The balloon positioning assembly includes two sets of lifting slide rods 5 fixedly connected to the upper end face of the positioning base 4. Positioning pressure plates 6 are slidably connected to the outer circumferential walls of both sets of lifting slide rods 5. Thin silicone gaskets 18 are provided on the upper end face of the positioning base 4 and the lower end face of the positioning pressure plates 6. A lifting adjustment mechanism is fixedly connected between the two positioning pressure plates 6. A support frame 8 is fixedly connected to the upper end of the plate 7 and the positioning base 4. A positioning drive component is fixedly connected to the middle of the support frame 8. The positioning drive component is used to drive the lifting adjustment plate 7 and the two positioning pressure plates 6 to move up and down. The positioning drive component includes a threaded sleeve 9 fixedly connected to the middle of the upper end of the support frame 8. An adjusting screw 10 is connected to the inner thread of the threaded sleeve 9. An adjusting knob 19 is fixedly connected to the upper end of the adjusting screw 10. Several anti-slip protrusions are fixedly connected to the outer peripheral wall of the adjusting knob 19. The lower end of the adjusting screw 10 is rotatably connected to the upper end of the lifting adjustment plate 7.

[0030] The adjusting screw 10 is turned by rotating the adjusting knob 19. The screw 10 and the threaded sleeve 9 are engaged to drive the lifting adjusting plate 7 and the two positioning pressure plates 6 to move downward. During this process, several lifting slide rods 5 can limit the downward movement of the two positioning pressure plates 6 to maintain the downward stability of the two positioning pressure plates 6. When the two positioning pressure plates 6 move down to contact the positioning base frame 4 and the balloon 2, the balloon 2 and the guide tube 1 can be accurately positioned on both sides to ensure the stability and bonding accuracy of the balloon 2 during subsequent bonding and to ensure the performance of the balloon guide tube.

[0031] Reference Figure 1 and Figure 5Two auxiliary bonding components are fixedly connected to the upper end of the support frame 8. The auxiliary bonding components are used to assist in completing the flanging and repositioning operation after the balloon is coated with glue. The auxiliary bonding components include a sliding frame 11 fixedly connected to the upper end of the support frame 8. A limit slider 12 is slidably connected to the sliding frame 11. A straight rod 13 is slidably connected through the middle of the limit slider 12. A traction ring 20 is fixedly connected to the upper end of the straight rod 13. A convex block 14 is fixedly connected to the lower end of the straight rod 13. A flap 15 is fixedly connected to the lower end of the convex block 14.

[0032] After the balloon 2 is positioned, the convex block 14 can be driven to move down by the traction ring 20, so that the flap 15 is fully attached to the balloon 2. When the balloon 2 is flipped and glue is applied to the balloon 2 and the guide tube 1, the flipped edge of the balloon 2 covers the flap 15. After the glue is applied, the traction ring 20 is quickly pulled and pushed horizontally, so that the convex block 14 can move up and slide horizontally a distance, so that the flipped edge of the balloon 2 begins to separate from the guide tube 1. This makes it easier for the operator to quickly reset the flipped edge of the balloon 2, which helps to improve the efficiency of the balloon 2 flipped edge reset operation, avoids the glue from solidifying, and ensures the bonding effect between the balloon 2 and the guide tube 1.

[0033] The auxiliary bonding component also includes a first micro magnet 16 fixedly connected to the upper end face of the convex block 14, and a second micro magnet 17 fixedly connected to the lower end face of the limiting slider 12. The first micro magnet 16 and the second micro magnet 17 are arranged to attract each other with opposite poles.

[0034] Pulling the traction ring 20 drives the convex block 14 and the flap 15 to move upward. The magnetic attraction between the first micro magnet 16 and the second micro magnet 17 can fix the convex block 14 to maintain the position of the flap 15 and prevent the flap 15 from affecting the placement and positioning of the guide tube 1 and the balloon 2.

[0035] The working principle of this utility model is as follows:

[0036] 1. In use, the adjusting screw 10 is turned by rotating the adjusting knob 19. The adjusting screw 10 and the threaded sleeve 9 are engaged to drive the lifting adjusting plate 7 and the two positioning pressure plates 6 to move downward. During this process, several lifting slide rods 5 can limit the downward movement of the two positioning pressure plates 6 to maintain the downward stability of the two positioning pressure plates 6. When the two positioning pressure plates 6 move down to contact the positioning base frame 4 and the balloon 2, the balloon 2 and the guide tube 1 can be accurately positioned on both sides to ensure the stability and bonding accuracy of the balloon 2 during subsequent bonding and to ensure the performance of the balloon guide tube.

[0037] 2. After the balloon 2 is positioned, the convex block 14 can be driven to move down by the drive traction ring 20, so that the flap 15 is fully attached to the balloon 2. When the balloon 2 is flipped and glue is applied to the balloon 2 and the guide tube 1, the flipped edge of the balloon 2 covers the flap 15. After the glue is applied, the convex block 14 can be moved up and slid horizontally a distance by quickly pulling and pushing the traction ring 20, so that the flipped edge of the balloon 2 can start to separate from the guide tube 1, so that the operator can quickly reset the flipped edge of the balloon 2. This helps to improve the operation efficiency of the flipped edge reset of the balloon 2, avoids the glue from solidifying, and ensures the bonding effect between the balloon 2 and the guide tube 1.

[0038] 3. Before the balloon 2 and guide tube 1 are positioned and bonded, the convex block 14 and the flap 15 can be moved upward by pulling the traction ring 20. The convex block 14 can be fixed by the magnetic attraction of the first micro magnet 16 and the second micro magnet 17 to maintain the position of the flap 15 and prevent the flap 15 from affecting the placement and positioning of the guide tube 1 and balloon 2.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
