Description

Technical Field

[0001] This utility model relates to the field of suture processing, and in particular to a device for attaching an antibacterial coating to cardiovascular sutures. Background Technology

[0002] Cardiovascular disease is one of the major diseases that seriously threaten human health worldwide. Cardiovascular sutures are often used in the treatment of cardiovascular diseases. With the continuous advancement of medical technology, the performance requirements for cardiovascular sutures are also increasing. The effective adhesion of antibacterial coatings to cardiovascular sutures can effectively reduce the risk of postoperative infection, improve the success rate of surgery and the quality of patient recovery.

[0003] Existing methods for applying antibacterial coatings to cardiovascular sutures typically involve immersing the suture in the coating or spraying it with a spray gun. However, current equipment lacks the ability to smooth the coating and control its thickness. During processing, this can easily lead to uneven distribution of the coating on the suture surface, resulting in areas that are too thick or too thin. This affects the quality and performance of the coating, reduces production efficiency and quality, and is very inconvenient to use.

[0004] Therefore, there is a need to design a flexible and convenient cardiovascular suture antibacterial coating application device that can simultaneously smooth and control the thickness of the coating after drying the suture before application, thereby improving coating adhesion and uniformity, increasing production efficiency and quality. Utility Model Content

[0005] To overcome the shortcomings of current equipment that lacks the function of smoothing the coating and controlling the coating thickness, which easily leads to uneven distribution of the coating on the suture surface during processing, resulting in localized areas that are too thick or too thin, affecting the quality and performance of the coating, reducing production efficiency and quality, and causing great inconvenience in use, this utility model provides a cardiovascular suture antibacterial coating application device that can smooth and control the coating thickness while applying the coating to the suture after drying it before application, improving coating adhesion and uniformity, increasing production efficiency and quality, and offering flexible and convenient use.

[0006] The technical solution is as follows: A cardiovascular suture antibacterial coating attachment device, comprising a support, a winding drum, a motor, a support plate, a spraying cylinder, a nozzle, a take-up drum, an adjustment component, and a drying component.

A spraying cylinder is connected to the upper side of the support plate on the right side. Multiple nozzles are connected to the inner side of the spraying cylinder. The output shaft of the motor on the right passes through the support and is engaged with the take-up drum. An adjustment component for adjusting the thickness of the antibacterial coating is located in the middle of the support. A drying component for progressively drying the antibacterial coating is located on the right side of the support.

[0007] In a preferred embodiment of this utility model, the adjustment component includes a locking pin, a lower clamping block, an upper clamping block, a forming ring, a slide rod, a spring, and an electric push rod. The upper part of the bracket is locked with a locking pin, and the lower clamping block is placed on the upper side of the upper part of the bracket. The locking pin is locked with the lower clamping block. Slide rods are connected to both the front and rear parts of the lower clamping block. The upper clamping block is slidably connected between the slide rods. Multiple forming rings are connected to the sides of the upper and lower clamping blocks that are close to each other. Springs are connected between the slide rods and the upper clamping block. An electric push rod is connected to the lower side of the upper part of the bracket. The electric push rod and the processor are electrically connected through a control module. The telescopic end of the electric push rod contacts the upper clamping block.

[0008] In a preferred embodiment of this utility model, the sliding rods are all T-shaped.

[0009] In a preferred embodiment of this utility model, the drying assembly includes a heating cylinder, heating lamps, a primary drying cylinder, a secondary drying cylinder, and a tertiary drying cylinder. The upper side of the support plate on the left is connected to the heating cylinder, and multiple heating lamps are connected to the inner side of the heating cylinder.

[0012] Beneficial effects: 1. This utility model moves a forming ring of corresponding thickness to a suitable position, and then the upper forming ring moves to contact the suture. The suture is dried by the heating lamp in the heating cylinder, and the coating is sprayed from the nozzle. The forming ring spreads the coating evenly on the surface of the suture and controls the thickness. Thus, the suture can be dried before coating and the coating can be applied to the suture while smoothing the coating and controlling the thickness. This improves the adhesion and uniformity of the coating, increases production efficiency and quality, and is flexible and convenient to use.

The motor 3 is connected to both the left and right sides of the bracket 1. The motor 3 and the processor are electrically connected via a control module. The output shaft of the left motor 3 passes through the bracket 1 and is engaged with the winding drum 2. Two support plates 4 are connected to the upper left side of the bracket 1, and the spraying cylinder 8 is connected to the upper side of the right support plate 4. Twelve nozzles 9 are connected to the inner side of the spraying cylinder 8. The output shaft of the right motor 3 passes through the bracket 1 and is engaged with the take-up drum 20. An adjustment assembly for adjusting the thickness of the antibacterial coating is located in the middle of the bracket 1, and a drying assembly for progressively drying the antibacterial coating is located on the right side of the bracket 1.

[0022] like Figure 3As shown, the adjustment assembly includes a locking pin 10, a lower clamping block 11, an upper clamping block 12, a forming ring 13, a sliding rod 14, a spring 15, and an electric push rod 16. The upper part of the bracket 1 is engaged with the locking pin 10. The lower clamping block 11 is placed on the upper side of the upper part of the bracket 1, and the locking pin 10 is engaged with the lower clamping block 11. The lower clamping block 11 is connected to both the front and rear parts of the lower clamping block 11, and the sliding rods 14 are all T-shaped for easy guidance. The upper clamping block 12 is slidably connected between the sliding rods 14. Five forming rings 13 are connected to the side of the upper clamping block 12 and the lower clamping block 11 that are close to each other. The springs 15 are connected between the sliding rods 14 and the upper clamping block 12. The electric push rod 16 is connected to the lower side of the upper part of the bracket 1. The electric push rod 16 and the processor are electrically connected through a control module. The telescopic end of the electric push rod 16 contacts the upper clamping block 12.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the drying assembly includes a heating cylinder 5, heating lamps 6, a primary drying cylinder 17, a secondary drying cylinder 18, and a tertiary drying cylinder 19. The heating cylinder 5 is connected to the upper side of the support plate 4 on the left, and five heating lamps 6 are connected to the inner side of the heating cylinder 5. The primary drying cylinder 17 is connected to the upper right side of the bracket 1, and five heating lamps 6 are also connected to the inner side of the primary drying cylinder 17. The secondary drying cylinder 18 is connected to the right side of the bracket 1, and five heating lamps 6 are also connected to the inner side of the secondary drying cylinder 18. The tertiary drying cylinder 19 is connected to the upper right side of the bracket 1. The primary drying cylinder 17 has the same specifications as the secondary drying cylinder 18 and the tertiary drying cylinder 19. Five heating lamps 6 are also connected to the inner side of the tertiary drying cylinder 19. The assembly also includes a guide ring 7. The guide ring 7 is connected to the inner side of the upper left part of the heating cylinder 5, and the guide ring 7 is also connected to the lower side of the upper right part of the tertiary drying cylinder 19 for guidance.

[0024] This device can be used when an antibacterial coating needs to be applied to cardiovascular sutures. The device involves bringing the support 1 into contact with the ground, then engaging the winding drum 2 with the cardiovascular suture to the output shaft of the left motor 3, and then engaging the take-up drum 20 with the output shaft of the right motor 3. Next, according to production requirements, the lower clamping block 11 is placed on the support 1, and then the lower clamping block 11 is moved to move the forming ring 13 of the corresponding thickness to the appropriate position. The locking pin 10 is then engaged with the support 1 and the lower clamping block 11 for fixation. Finally, the suture is pulled to move through the left guide ring 7, the spraying cylinder 8, the corresponding forming ring 13, and then through the primary drying cylinder 17. The secondary drying drum 18 and the tertiary drying drum 19 extend from the right-hand guide ring 7 and are wound around the take-up drum 20. Then, the processor activates the electric push rod 16 via the control module. The telescopic end of the electric push rod 16 extends and contacts the upper clamping block 12, causing the upper clamping block 12 to move along the slide rod 14. The spring 15 is stretched, causing the upper forming ring 13 to move and contact the suture thread. The slide rods 14 are all T-shaped for easy guidance. Next, the processor activates the motor 3 via the control module. The motor 3 drives the take-up drum 20 to rotate for unwinding and rewinding, causing the suture thread to move. Simultaneously, the heating drum 5... The heating lamp 6 illuminates to dry the suture. After drying, the paint is introduced into the spray gun 8 and sprayed out from the nozzle 9, allowing the paint to adhere to the suture. As the suture continues to move, the forming ring 13 evenly spreads the paint on the suture surface and controls the thickness. This allows for simultaneous drying of the suture before coating and coating application, while also smoothing and controlling the thickness of the coating, improving adhesion and uniformity, increasing production efficiency and quality. The process is flexible and convenient. The heating lamp 6 in the primary drying cylinder 17, secondary drying cylinder 18, and tertiary drying cylinder 19 illuminates, causing the temperature of the heating lamp 6 to gradually increase from left to right. The temperature is increased, and the coated suture is gradually dried by varying the temperature. The dried suture is then wound onto the take-up drum 20 for collection. The primary drying drum 17 is identical in specifications to the secondary drying drum 18 and the tertiary drying drum 19, allowing for gradual drying of the suture at different temperatures after coating. This prevents excessively rapid drying, which could lead to solvent residue or bubble formation, and also prevents coating cracking or shrinkage, further improving production quality. After coating is complete, the motor 3 is turned off, and the winding drum 2 and the take-up drum 20 are removed. The electric push rod 16 then reverses its movement, causing its extension end to retract and return to its original position. The spring 15 rebounds, and the upper clamping block 12 moves in the opposite direction along the slide rod 14 to reset.This causes the corresponding forming ring 13 to move and reset, then a new winding drum 2 and a take-up drum 20 are installed, and the above operation is repeated to continue applying the antibacterial coating to the suture.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
