Description

Technical Field

[0001] This invention relates to the field of suture manufacturing equipment technology, and more particularly to a production equipment for collagen absorbable medical sutures. Background Technology

[0002] Sutures with needles are mainly used for suturing in general surgical procedures, such as obstetrics and gynecology, general surgery, urology, plastic surgery, orthopedics, thoracic surgery, and ophthalmology. In the production process of sutures with needles, the suture needs to be threaded through the needle eye, and then a suture presser is used to flatten the needle end at the junction of the needle eye and the suture, connecting the needle and the suture. To minimize scarring after suturing, current technologies often use collagen material in the manufacture of sutures; however, the suture material is relatively soft, and multi-strand sutures are prone to splitting, making it difficult to thread the suture through the needle eye during the needle insertion process. Coating the surface of the suture with a hardener binds the multi-strand sutures together, increasing the hardness of the needle insertion area, effectively reducing the difficulty of threading and improving the efficiency of needle insertion.

[0003] Common methods for applying hardener to sutures include spraying, dipping, and brushing. For example, US Patent 5425746 discloses a spraying method for applying hardener to sutures. This method requires placing the suture-wound roller in a confined space for spraying; otherwise, the large amount of solvent evaporation will be detrimental to the management of the cleanroom and the health of the operators. US Patent 3890975 discloses a dipping method for applying hardener to sutures. This process involves winding the suture onto a roller and then immersing the portion to be coated with hardener in the hardener. This process requires a large amount of hardener and uses large containers, resulting in significant solvent evaporation, which is detrimental to the management of the cleanroom and the health of the operators. Furthermore, dipping can lead to uneven hardener coating thickness. Some manufacturers manually brush the hardener onto the suture after winding. This brushing method effectively avoids the problems of large solvent evaporation and excessive hardener waste. However, due to manual application, there are problems such as uneven hardener coating, difficulty in controlling coating thickness, high labor intensity, and high production costs.

[0004] Therefore, there is a need for a production equipment for absorbable collagen medical sutures that do not require the use of a hardening agent that is harmful to human health during the assembly of sutures and needles. Summary of the Invention

This achieves the technical effect that the production equipment for medical sutures does not require the use of hardening agents that are harmful to the human body when assembling sutures and suture needles, and the assembly process has a low labor intensity.

The axial direction of the support rods 122 is the same as the axial direction of the rotation axis of the thread roller. The rotation drive assembly 130 is a motor used to drive the feed roller 110 and the feed roller 120.

[0080] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the cutting blade assembly 200 includes a support frame 210, a support block 220, a blade support plate 230, a cutting blade 240, a pad 250, and a clamping plate 260. The support frame 210 provides support and includes a support guide rail 211, which is a straight guide rail with its length direction aligned with the axial direction of the winding roller and located on one side of the winding roller. The support block 220 is slidably positioned on the support guide rail 211 to support the blade support plate 230 and the pad 250. The blade support plate 230 is slidably positioned on the support block 220 along the height direction of the equipment and slides under the control of the control unit to support the cutting blade. The functions of the cutting tool 240 and the clamping plate 260 are as follows: The cutting tool 240 is generally long and narrow, and is fixed on the tool support plate 230; the pad 250 is fixed on the support block 220, and the pad 250 is located directly below the cutting tool 240. The downward movement of the cutting tool 240 cooperates with the pad 250 to cut the suture thread; the clamping plate 260 is a long and narrow rubber plate, fixed on the tool support plate 230 and set close to the cutting tool 240. When the tool support plate 230 moves downward, the clamping plate 260 abuts against the pad 250, clamping and fixing the end of the suture thread away from the thread end covering assembly 300.

[0081] The thread end covering assembly 300 is used to cover one of the thread ends of the suture with paraffin wax mixed with iron powder or magnetic powder, and includes a fixed base plate 310, a cover plate assembly 390 and a paraffin wax chamber 380.

[0082] The fixed base plate 310 is a rectangular plate that is fixed on the winding roller. The length direction of the fixed base plate 310 is the same as the axial direction of the winding roller.

The length direction of the rope groove is perpendicular to the length direction of the fixed base plate 310 and the rope groove passes through the fixed base plate 310. The spacing between the rope grooves is preferably 2 cm.

[0084] The rope groove consists of a guide part 320 and a covering part 330, with the covering part 330 close to the cutting tool 240. The width of the guide part 320 is greater than or equal to the diameter of the suture line. The length of the covering part 330 is less than 1.5 cm, and the width is greater than the diameter of the suture line. Both ends of the covering part 330 are provided with adhesive strips 340, which are made of rubber material and are used to adhere tightly to the suture line to prevent liquid paraffin from flowing out of the covering part 330 when it is filled with paraffin. When the rotating plate 392 abuts against the fixed base plate 310, the covering part 330, the adhesive strips 340, the suture line, and the rotating plate 392 together form a tubular space for filling with paraffin.

[0085] like Figure 5 and Figure 7 As shown, the cover plate assembly 390 includes a support body 391 and a rotating plate 392; the support body 391 is a rod or frame structure used to support and position the rotating plate 392; one end of the rotating plate 392 is rotatably and fixedly connected to the support body 391, and rotates under the control of the control unit; when the rotating plate 392 rotates to a horizontal state, it completely covers the fixed base plate 310, at which time the bottom surface of the rotating plate 392 is attached to the top surface of the fixed base plate 310; the rotating plate 392 is provided with a wax injection hole 370 corresponding to the covering part 330, and the wax injection hole 370 is connected to the paraffin wax tank 380;

[0087] The filling material inside the paraffin chamber 380 is a mixture of paraffin wax and iron powder and / or magnetic powder, wherein the paraffin wax content is not less than one-half.

[0088] Furthermore, the attached soft strip 340 is generally ring-shaped, including a ring-shaped strip 341 and a soft block 342; the ring-shaped strip 341 is fixed at both ends of the covering part 330; the soft block 342 is fixed on the rotating plate 392, and the ring-shaped strip 341 and the soft block 342 are combined to form a ring.

[0089] like Figure 8As shown, the suture needle clamping assembly 400 is used to clamp and fix the suture needle, and is a clamp body. There are multiple clamps, which are fixed on a horizontal ground. The needle hole squeezing assembly 500 is used to squeeze the tail of the suture needle, thereby fixing the suture thread on the suture needle.

[0105] In actual use, under the control of the control unit, the column 610 picks up the thread end wrapped with paraffin wax and then puts it into the secondary coating groove 350. In the secondary coating groove 350, a layer of pure paraffin wax is wrapped again. Finally, the column 610 is used to thread the thread end into the suture needle.
