Description

Technical Field

[0001] This utility model relates to the field of vascular closure device processing technology, specifically a vascular closure device wire forming machine. Background Technology

[0002] A vascular closure device is a medical device used for hemostasis at the puncture site after interventional surgery. It replaces traditional manual compression with mechanical occlusion or bio-coagulation, significantly shortening hemostasis time and reducing the risk of complications. The vascular closure device uses a nickel-titanium alloy or stainless steel wire for rapid occlusion of the vascular puncture site, achieving minimally invasive hemostasis through shape memory or mechanical support. During the manufacturing process of the vascular closure device wire, to ensure high-precision 3D bending of materials such as nickel-titanium alloys and to ensure the shape memory performance and mechanical properties of the vascular occlusion structure, a vascular closure device wire forming machine is required. However, current forming machines still have the following shortcomings:

[0003] For example, patent document CN218611419U discloses a metal wire bending and forming device. This metal wire bending and forming device can adapt to various working conditions by adjusting the position of the workpiece placement disc. The overall structure is very simple and flexible and very convenient to use. However, it is not easy to maintain a stable feeding of the metal wire, and the movement of the metal wire is prone to deviation. Moreover, the movement of the metal wire is not monitored in real time, so it is impossible to guarantee the uniformity of the length and quality of the metal wire. Utility Model Content

[0013] This utility model provides a metal wire forming machine for blood vessel closure devices, which has the following beneficial effects:

[0014] 1. This utility model incorporates auxiliary components, including a support column, a support groove, a wire feeding mechanism, a wire straightener, a fixed column, a limiting support cylinder, a laser rangefinder, and a PLC control panel. In use, the wire passes through the support groove, is supported by the support column, and then passes through the wire feeding mechanism, which automatically moves the wire forward. The wire moves to the inside of the wire straightener, where it is straightened. Finally, the wire passes through the limiting support cylinder, where the fixed column keeps the wire at a uniform horizontal level, preventing deviation in its path. The laser rangefinder monitors the wire's movement distance in real time, and the PLC control panel receives real-time feedback after each specified distance movement. The PLC control panel automatically stops the wire feeding mechanism, ensuring uniform length for each wire segment.

After moving to a suitable distance, the servo motor is started, causing the servo motor to drive the movable disc to rotate. The movable disc drives the bending rollers to rotate, causing the bending rollers to bend and form the metal wire. The hydraulic push rod is then started, causing the hydraulic push rod to drive the cutting tool downward to the cutting groove to cut the metal wire. Thus, the device can realize the bending and forming of metal wire and can automatically cut the metal wire, improving the overall processing efficiency. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3As shown, a vascular closure device wire forming machine includes a forming operation table 1 and an auxiliary component 3. The forming operation table 1 is an integrated structure, and a support base 2 is installed on the lower surface of the forming operation table 1. The auxiliary component 3 is disposed on the upper surface of the forming operation table 1, and the auxiliary component 3 includes a support column 301, a support groove 302, a wire feeding mechanism 303, a wire straightener 304, a fixed column 305, a limiting support cylinder 306, a laser rangefinder 307, and a PLC control panel 308. The support column 301 is disposed on the right side of the forming operation table 1, and the support groove 302 is installed on the top of the support column 301. The support column 301 is a tightly integrated structure. A wire feeding mechanism 303 is provided on the right end of the upper surface of the forming operation table 1, and a wire straightener 304 is installed on the left side of the wire feeding mechanism 303. The lower surface of the wire straightener 304 is connected to the upper surface of the forming operation table 1, and a fixed column 305 is installed on the left side of the wire straightener 304. A limit support cylinder 306 is provided on the top of the fixed column 305, and the limit support cylinder 306 and the fixed column 305 are a tightly integrated structure. A laser rangefinder 307 is provided on the front left side of the forming operation table 1, and a PLC control panel 308 is installed on the left front side of the forming operation table 1.

[0022] The specific operation is as follows: When in use, the metal wire is passed through the support groove 302, and the metal wire is assisted by the support column 301. The metal wire passes through the wire feeding mechanism 303, which drives the metal wire to move forward automatically. The metal wire moves to the inside of the metal wire straightener 304, where it is straightened. The metal wire passes through the limiting support cylinder 306, and the fixed column 305 keeps the metal wire at a uniform horizontal line to prevent deviation of the metal wire's movement path. The movement distance of the metal wire is monitored in real time by the laser rangefinder 307. After the metal wire moves a specified distance each time, the feedback is sent to the PLC control screen 308 in real time. The PLC control screen 308 automatically controls the wire feeding mechanism 303 to stop running, which can ensure that the length of each metal wire segment is uniform.

[0023] Please refer to Figure 3The lower surface of the forming operation table 1 is tightly connected to the upper surface of the support base 2. A support plate 4 is installed on the left end of the upper surface of the forming operation table 1. A forming component 5 for bending and forming is provided on the surface of the support plate 4. The forming component 5 includes an auxiliary fixing seat 501, a cutting groove 502, a fixing plate 503, a hydraulic push rod 504, and a cutting tool 505. The auxiliary fixing seat 501 is located on the left surface of the support plate 4, and a cutting groove 502 is opened on the upper surface of the auxiliary fixing seat 501. A fixing plate 503 is installed at the upper end of the left surface of the support plate 4, and the upper surface of the fixing plate 503 is... The support plate 4 is provided with a hydraulic push rod 504, and a cutting tool 505 is installed at the bottom of the hydraulic push rod 504. The forming component 5 also includes a fixed plate 506, a protective cylinder 507, a servo motor 508, a movable plate 509, and a bending roller 510. The fixed plate 506 is installed at the rear end of the left surface of the support plate 4. The protective cylinder 507 is provided at the left end of the surface of the fixed plate 506. The servo motor 508 is installed inside the protective cylinder 507. The output end of the servo motor 508 is connected to the movable plate 509 through a coupling. The bending roller 510 is provided on the right surface of the movable plate 509.

[0024] The specific operation is as follows: When in use, the wire feeding mechanism 303 drives the metal wire through the surface of the support plate 4 and through the limiting groove on the upper surface of the auxiliary fixing seat 501. After moving to a suitable distance, the servo motor 508 is started, which drives the movable plate 509 to rotate. The movable plate 509 drives the bending roller 510 to rotate, so that the bending roller 510 bends the metal wire. The hydraulic push rod 504 is started, which drives the cutting tool 505 to move downward into the cutting groove 502 to cut the metal wire.

[0025] In summary, as Figures 1 to 3As shown, in use, the metal wire forming machine for vascular closure devices first passes the metal wire through the support groove 302. The support column 301 provides auxiliary support for the metal wire. The wire then passes through the wire feeding mechanism 303, which drives the wire to move forward automatically. The wire moves to the inside of the wire straightener 304, where it is straightened. The wire then passes through the limiting support cylinder 306. The fixed column 305 keeps the wire at a uniform horizontal line, preventing deviation of the wire's movement path. The wire feeding mechanism 303 drives the wire through the surface of the support plate 4 and from the limiting position on the upper surface of the auxiliary fixing seat 501. The wire passes through the slot, and the movement distance of the metal wire is monitored in real time by the laser rangefinder 307. After the metal wire moves a specified distance each time, the feedback is sent to the PLC control panel 308 in real time. The PLC control panel 308 automatically controls the wire feeding mechanism 303 to stop running, which can ensure that the length of each metal wire segment is uniform. After moving to a suitable distance, the servo motor 508 is started, which drives the movable disk 509 to rotate. The movable disk 509 drives the bending roller 510 to rotate, so that the bending roller 510 bends and shapes the metal wire. The hydraulic push rod 504 is started, which drives the cutting tool 505 to move downward into the cutting slot 502 to cut the metal wire.
