Description

Technical Field

[0001] The present invention relates to the field of guide wire bending, and in particular to an automatic guide wire bending device. Background Art

[0002] Currently, most existing intubation guidewires rely on manual bending. Manual operation has many disadvantages. It cannot accurately guarantee the bending size. In medical scenarios where high guidewire bending accuracy is required, this may cause deviations during the intubation process, affecting the treatment effect and even causing medical risks. Moreover, during the bending process of guidewires made of some special materials, rebound deformation is prone to occur due to the material properties. In order to overcome rebound deformation, additional heating treatment is often required. This process not only increases the complexity and time cost of the operation, but also places higher demands on the technical experience of the operator.

[0003] At the same time, when a traditional guidewire is bent, the heating source and the guidewire remain relatively stationary. At this time, due to the local high temperature of the heating source, the part of the guidewire in contact with the heating source will continue to be in a high temperature environment when the guidewire is fixed. This can easily lead to excessive heating of this part of the guidewire, causing uneven changes in the microstructure of the guidewire material, such as distortion of the crystal structure or uneven grain growth, resulting in a decrease in the mechanical properties of the guidewire, such as reduced strength and poor toughness. Moreover, fixed heating can easily form local high-temperature oxidation points or thermal stress concentration areas on the surface of the guidewire, which not only affects the surface quality of the guidewire, reducing its smoothness, and increasing the friction resistance with human tissue during subsequent intubation operations, but may also become a potential risk point for guidewire breakage.

[0037] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] refer to Figures 1 to 11 , a guide wire automatic bending device, comprising:

[0039] Workbench 1;

[0040] The rotating mechanism 4 is arranged at one end of the workbench 1, and includes a supporting platform 5, a servo motor 6, a rotating shaft 8, a fixed tube 12, a rotating base 21, a guide cylinder 22 and a pulling cylinder 25. The supporting platform 5 is fixedly connected to the workbench 1, the servo motor 6 is fixedly connected to the lower end of the supporting platform 5, the rotating base 21 is rotatably connected to the upper end of the supporting platform 5 and is fixedly connected to the output end of the servo motor 6, the rotating shaft 8 is coaxially arranged with the output end of the servo motor 6 and is against the upper end of the rotating base 21, and the fixed tube 12 is arranged above the rotating shaft 8 (combined with Figure 6 and Figure 7 ), the pulling cylinder 25 is provided on one side of the rotating shaft 8 close to the edge of the supporting platform 5, and the guide cylinder 22 is provided on the side of the rotating shaft 8 away from the pulling cylinder 25;

[0041] The heating mechanism 28 is provided beside the support platform 5 and heats the bent guide wire 2;

[0042] The pulling mechanism 32 is connected to the workbench 1 and limits the guide wire 2 .

[0043] When the device is in operation, the head of the guide wire 2 extends from the side of the rotating shaft 8 and is clamped by the pulling cylinder 25. Then the servo motor 6 starts and drives the rotating base 21 to rotate. When the rotating base 21 rotates, the guide wire 2 will bypass the rotating shaft 8 and bend. Then the heating mechanism 28 approaches the rotating shaft 8 and heats the bent part of the guide wire 2. The pulling cylinder 25 drives the guide wire 2 to move back and forth during the heating process of the guide wire 2, so that the bent part of the guide wire 2 can be evenly heated during the heating process. The pulling mechanism 32 limits the guide wire 2 to ensure that the guide wire 2 can remain taut during the processing.

[0044] In order to supplement the specific structure of the rotating mechanism 4, the following features are also provided:

[0045] The rotating mechanism 4 also includes a main frame 7, a supporting frame 9, a carrier 10 and a screw sleeve 11. The middle of the rotating shaft 8 is formed with an annular groove 81 (refer to Figure 7 ), the main frame 7 is fixedly connected to the upper end of the rotating base 21 (reference Figure 6), the lower end of the rotating shaft 8 passes through the main frame 7 and abuts against the rotating base 21, the supporting frame 9 is arranged on the side of the main frame 7 and is fixedly connected to the rotating base 21, the carrier 10 is fixedly connected to the upper end of the supporting frame 9, the screw sleeve 11 is fixedly connected to the upper end of the carrier 10, the rotating shaft 8 and the screw sleeve 11 are coaxially arranged, and the screw sleeve 11 is threadedly connected to the fixed pipe 12 (reference Figure 11 When installing the rotating shaft 8, the operator sequentially passes the rotating shaft 8 of corresponding specifications through the screw sleeve 11, the carrier 10 and the main frame 7, and then presses it downward against the rotating base 21. The operator then screws the fixed tube 12 onto the screw sleeve 11. The annular groove 81 in the middle of the rotating shaft 8 will limit the bent guide wire 2. Different sizes of rotating shafts 8 will cause the bent guide wire 2 to generate different diameters of the bending angle.

[0046] In order to quickly install the rotating shaft 8, the following features are also provided:

[0047] The rotating mechanism 4 also includes a top plate 17, a push plate 20, a plurality of return springs 16, a plurality of springs 13, a plurality of contact pressure rods 15 and a plurality of balls 14, and the plurality of springs 13 are arranged in an array at equal angles along the circumferential direction of the inner wall of the screw sleeve 11 (refer to Figure 11 ), one end of a plurality of springs 13 is fixedly connected to the inner wall of the screw sleeve 11, and the other end is against the outer wall of the rotating shaft 8. The top plate 17 is fixedly connected to the upper part of the fixed tube 12 coaxially. The push plate 20 is slidably arranged above the top plate 17. A plurality of touch and pressure rods 15 are arranged in an array at equal angles along the circumference of the push plate 20. The upper end of the touch and pressure rods 15 is fixedly connected to the push plate 20, and the lower end is slidably connected to the top plate 17. A plurality of balls 14 are respectively rotatably connected to the lower ends of the plurality of touch and pressure rods 15. A plurality of return springs 16 are respectively sleeved on the outside of the plurality of touch and pressure rods 15. The upper end of the return spring 16 is fixedly connected to the push plate 20, and the lower end is fixedly connected to the top plate 17. After the rotating shaft 8 is inserted into the screw sleeve 11, the rotating shaft 8 will pass through the plurality of springs 13 and be tightened by the plurality of springs 13. At this time, the rotating shaft 8 completes the first limit. The operator then screws the fixed pipe 12 onto the outside of the nut 11 until the top plate 17 and the upper end of the rotating shaft 8 are against each other. Now, a number of balls 14 are located above a number of reeds 13 and the two do not counteract each other.

[0048] In order to achieve secondary reinforcement of the rotating shaft 8, the following features are specifically provided:

[0049] The rotating mechanism 4 also includes a knob 18 and a screw 19. The screw 19 is threadedly connected to the upper end of the fixed tube 12 and the lower end thereof abuts against the push plate 20 (refer to FIG. Figure 11), the knob 18 is fixedly connected to the upper end of the screw 19. After the top plate 17 abuts against the upper end of the rotating shaft 8, the operator turns the knob 18 and drives the screw 19 to move downward. At this time, the movement of the screw 19 pushes the push plate 20 to move downward. After the push plate 20 moves, it drives the corresponding balls 14 to move through the contact rods 15 until the balls 14 abut against the upper end of the spring 13 and cause the spring 13 to undergo secondary deformation (such as Figure 11 As shown), the spring 13 will finally reinforce the rotating shaft 8 for a second time to prevent the guide wire 2 from moving during the bending process.

[0050] In order to achieve the goal of not damaging the exterior of the guide wire 2 when the cylinder 25 is pulled back and forth to pull the guide wire 2, the following features are specifically provided:

[0051] The rotating mechanism 4 also includes two clamping claws 26 and two anti-slip gaskets 27. The two clamping claws 26 are symmetrically connected to the output end of the pulling cylinder 25 (refer to Figure 7 ), two anti-slip washers 27 are respectively fixedly connected to the sides of the two clamping jaws 26. When the pulling cylinder 25 is activated, the pulling cylinder 25 drives the two anti-slip washers 27 to approach the guide wire 2 through the two clamping jaws 26. Then, the pulling cylinder 25 drives the guide wire 2 to move in a reciprocating motion, so that the heating mechanism 28 can evenly heat the bend.

[0052] In order to facilitate the guide cylinder 22 to guide the guide wire 2, the following features are also provided:

[0053] The rotating mechanism 4 further includes two guide blocks 23, which are respectively fixed to the output ends of the guide cylinder 22 (refer to Figure 3 ), the two guide blocks 23 are formed with a guide groove 24 on the side closest to each other to limit the position of the guide wire 2. When the guide wire 2 is pulled by the pulling cylinder 25, the guide wire 2 first passes through the guide groove 24 for position control. During the rotation of the rotating base 21, the guide cylinder 22 drives the two guide blocks 23 to move away from each other to avoid the guide wire 2 in the bending process and prevent the guide wire 2 from colliding with the guide blocks 23 during the bending process.

[0054] In order to supplement the specific structure of the heating mechanism 28, the following features are also provided:

[0055] The heating mechanism 28 also includes a push cylinder 29, a lifting cylinder 30 and a heating gun 31 (refer to Figure 1), the lifting cylinder 30 is fixedly connected to the workbench 1, the pushing cylinder 29 is fixedly connected to the output end of the lifting cylinder 30, and the heating gun 31 is fixedly connected to the output end of the pushing cylinder 29. After the rotating base 21 rotates, the lifting cylinder 30 is activated and drives the pushing cylinder 29 upward. The activation of the pushing cylinder 29 drives the heating gun 31, which is fixedly connected to its output end, close to the guide wire 2 being bent. The subsequent activation of the heating gun 31 can evenly heat the bend of the guide wire 2, improving the quality of the bent guide wire 2.

[0056] In order to position the guide wire 2 and prevent the guide wire 2 from moving before being clamped by the pulling cylinder 25, the following features are also provided:

[0057] The pulling mechanism 32 also includes a head end clamping cylinder 37, a tail end clamping cylinder 38, a first transfer plate 39, a second transfer plate 40 and four rubber clamping blocks 41. The upper end of the workbench 1 is formed with an avoidance hole 3 (refer to Figure 4 ), the first transfer plate 39 is arranged at the upper end of the workbench 1 and is located on the side of the avoidance hole 3 close to the supporting platform 5, the second transfer plate 40 is arranged just below the avoidance hole 3 and is fixedly connected to the workbench 1, the head end clamping cylinder 37 is fixedly connected to the first transfer plate 39, the tail end clamping cylinder 38 is fixedly connected to the second transfer plate 40, and the output ends of the head end clamping cylinder 37 and the tail end clamping cylinder 38 are respectively fixedly connected to two rubber clamping blocks 41 (reference Figure 5 Before the guide wire 2 is bent, the head end clamping cylinder 37 and the tail end clamping cylinder 38 are activated and respectively clamp the guide wire 2 through the corresponding rubber clamping blocks 41 to prevent the guide wire 2 from deviating and affecting the bending effect. At the same time, the rubber clamping blocks 41 protect the guide wire 2 and prevent the guide wire 2 from being damaged due to excessive clamping force when being clamped.

[0058] In order to ensure that the guide wire 2 moves straight and prevent the guide wire 2 from curling up, the following features are specifically provided:

[0059] The pulling mechanism 32 further includes a pulling frame 36, a limiting roller 42 and a weight 35. The pulling frame 36 is arranged below the workbench 1 and is fixedly connected to the workbench 1 (refer to FIG. Figure 5 ), a limiting roller 42 is rotatably mounted on the end of the pulling frame 36 away from the support platform 5, contacting the guide wire 2. The weight 35 is fixedly connected to the end of the guide wire 2 away from the support platform 5. To maintain tension during bending, the weight 35 pulls the end of the guide wire 2 away from the support platform 5. This allows the guide wire 2 to remain taut while being pulled by the pulling cylinder 25. The limiting roller 42 ensures smooth movement of the guide wire 2.

[0060] In order to facilitate the guide wire 2 to maintain tension during movement, the following features are specifically provided:

[0061] The pulling mechanism 32 also includes an extrusion roller 33 and a transfer roller 34. The extrusion roller 33 is arranged on the side of the first transfer plate 39 near the avoidance hole 3. The extrusion roller 33 is rotatably connected to the upper end of the workbench 1 via a wheel seat. The transfer roller 34 is arranged below the extrusion roller 33 and rotatably connected to the lower end of the workbench 1 via a wheel seat. The transfer roller 34 and the extrusion roller 33 limit the moving guide wire 2. During the movement of the guide wire 2, the extrusion roller 33 and the transfer roller 34 ensure that the guide wire 2 does not deflect, thereby improving the quality of the guide wire 2 after bending.

[0062] The working principle of this device is that when the device is in operation, the operator first positions and installs the guide wire 2. During this process, the head end clamping cylinder 37 and the tail end clamping cylinder 38 are started and respectively clamp the guide wire 2 through the corresponding rubber clamping blocks 41 to prevent the guide wire 2 from deviating and affecting the bending effect. At the same time, the rubber clamping blocks 41 will protect the guide wire 2 to prevent the guide wire 2 from being damaged due to excessive clamping force when being clamped.

[0063] Then the head of the guide wire 2 extends out from the side of the rotating shaft 8 and is clamped by the pulling cylinder 25, and the servo motor 6 starts and drives the rotating base 21 to rotate. During the rotation of the rotating base 21, the guide cylinder 22 will drive the two guide blocks 23 to move away from each other so as to avoid the guide wire 2 in the bending process and prevent the guide wire 2 from colliding with the guide blocks 23 during the bending process.

[0064] The guide wire 2 will then pass around the rotating shaft 8 and bend. Subsequently, the heating gun 31 approaches the rotating shaft 8 under the action of the lifting cylinder 30 and the pushing cylinder 29 and heats the bent part of the guide wire 2. The pulling cylinder 25 will drive the guide wire 2 to move back and forth during the heating process, so that the bent part of the guide wire 2 can be evenly heated during the heating process.

[0065] The weight 35 will pull the end of the guide wire 2 away from the support platform 5, so that when the guide wire 2 is pulled by the pulling cylinder 25, the guide wire 2 can remain taut while keeping moving.

[0066] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
