Description

Technical Field

[0001] The utility model relates to the technical field of fishbone wire production, in particular to a fishbone wire cutting device capable of preventing waste scraps from sticking. Background Art

[0002] Fishbone sutures, also known as fishbone-type barbed wires, are a special type of surgical suture with paired blunt-edged fishbone-like protrusions on both sides. The advantage of barbed wires is that they do not need to be knotted, and once the suture is tightened, they are not easy to loosen, so they have a huge advantage in situations where knotting and thread lifting are inconvenient. For general surgery, this situation is laparoscopic surgery, such as laparoscopic gastrointestinal anastomosis and closure of the pelvic peritoneum after laparoscopic rectal cancer resection. The use of barbed wires can make suturing easier and can greatly shorten the time required for suturing.

[0003] Cutting on a single strand of wire can produce barbs one by one, thereby making a fishbone wire, which then needs to be cut into different lengths. During the existing cutting of the fishbone wire, there is a problem that the waste generated at the broken end of the fishbone wire is easy to stick to the surface of the cutting knife; therefore, the existing needs are not met, and a fishbone wire cutting device that prevents the waste from sticking is proposed. Utility Model Content

[0022] The fishbone wire body 4 first passes through the middle of the first turntable 3 and the second turntable 301, then passes through the middle of the top block 501 and the pressing block 5, and finally passes through the cutting component 1. The first turntable 3 and the second turntable 301 rotate simultaneously to provide a stable force for the fishbone wire body 4 to move forward. When one end of the fishbone wire body 4 reaches a predetermined length, the first turntable 3 and the second turntable 301 stop rotating, the pressing block 5 presses the top block 501, and the fishbone wire body 4 is fixed between the top block 501 and the pressing block 5. The cutting component 1 then cuts the fishbone wire body 4 to avoid the situation where the cut fishbone wires are of different lengths, further improving the stability of the cutting operation.

[0023] The cutting assembly 1 includes a positioning plate 101, a cutting knife 102, a fixed bin 103, a scraper 104, a collecting box 105, a support plate 106 and a piston rod 107, one end of the piston rod 107 is connected to the cutting knife 102, one end of the piston rod 107 is connected to the support plate 106, the cutting knife 102, the fixed bin 103 and the scraper 104 are located inside the positioning plate 101; a first through groove 1011 and an installation space 1013 are provided inside the positioning plate 101, a second through groove 1012 is provided on the side of the positioning plate 101, the fixed bin 103 and the scraper 104 are located inside the first through groove 1011, the collecting box 105 is located below the first through groove 1011, and the cutting knife 102 is located inside the installation space 1013.

[0024] A limiting block 1021 is provided on the side of the cutting knife 102, a cutting head 1022 is provided at one end of the cutting knife 102 facing the inside of the positioning plate 101, a fixing column 1031 and a spring 1032 are provided inside the fixed bin 103, a third through slot 1033 is provided below the fixed bin 103, a slider 1041 is provided above the scraper 104, the slider 1041 is sleeved on the fixing column 1031, the slider 1041 is connected to the scraper 104 through a connecting column 1042, the connecting column 1042 is located inside the third through slot 1033, the collecting box 105 is installed below the bottom plate 2, and the internal spaces of the first through slot 1011, the fourth through slot 201 and the collecting box 105 are connected.

[0025] The piston rod 107 pushes the cutting knife 102 to move forward. After the cutting knife 102 cuts the fishbone wire body 4 into two sections, the cutting knife 102 is reset. The next time the cutting knife 102 moves forward for cutting, the cutting knife 102 passes through the middle of the two scrapers 104. The spring 1032 squeezes the slider 1041 toward the middle inside the fixed bin 103. The slider 1041 drives the scraper 104 to squeeze against the surface of the blade head 1022 of the cutting knife 102, thereby removing the waste chips stuck on the blade head 1022 of the cutting knife 102. The waste chips fall along the scraper 102 into the collecting box 105 below, avoiding the situation where the waste chips accumulate on the surface of the cutting knife 102 and cause the life of the cutting knife 102 to decrease, thereby further improving the production efficiency.

[0026] When the cutting knife 102 passes through the middle of the two scrapers 104 , the limiting block 1021 abuts against the scraper 102 , thereby preventing the scraper 102 from wearing the blade of the cutting knife 104 , and further improving the life of the cutting knife 102 .

[0027] Working principle: the fishbone wire body 4 first passes through the middle of the first turntable 3 and the second turntable 301, then passes through the middle of the top block 501 and the pressure block 5, and finally passes through the cutting component 1. When one end of the fishbone wire body 4 reaches a predetermined length, the first turntable 3 and the second turntable 301 stop rotating, the pressure block 5 presses the top block 501, the fishbone wire body 4 is fixed between the top block 501 and the pressure block 5, and the cutting component 1 cuts the fishbone wire body 4. When waste chips stick to the cutting knife 102, the scraper 104 removes the waste chips stuck to the blade head 1022 of the cutting knife 102, and the waste chips fall along the scraper 104 into the collecting box 105 below, thereby improving production efficiency.
