Technical Field
[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a barbed suture cutting machine. Background Art
[0002] A barbed suture cutting machine is a device specialized for processing medical suture lines. It can form barbed structures on the surface of the suture lines. A barbed suture is a knotless suture line with barbed structures on its surface. When suturing tissues, these barbs penetrate into the tissue interior and lock it in place, eliminating the need to tie knots to secure the suture line. This is convenient in operation, reduces the operation time, and has high safety. The basic function of a barbed suture cutting machine is to process barbed suture lines with different specifications and characteristics according to different medical needs to meet the suture requirements of different surgical sites.
[0003] When a barbed suture cutting machine cuts a suture line, it moves a cutting knife to cut the surface of the suture line. Most of the cutting knives of existing barbed suture cutting machines are driven by cylinders. Although the cylinder can provide power for the movement of the cutting knife, the repeated movement efficiency of the cylinder is low, and the production efficiency of the barbed suture cutting machine cannot be improved. To solve this technical problem, the utility model proposes a barbed suture cutting machine. Summary of the Utility Model

Specific embodiments
[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] As Figures 1-5 shown, a barbed wire cutting machine includes a cabinet 1. Two support seats 2 are connected to the upper surface of the cabinet 1, and the two support seats 2 are symmetrical. The inner walls of the two support seats 2 are connected with a sleeve 3, and the inner wall of the sleeve 3 is connected with a wire seat 4. The stability of the sleeve 3 is maintained by the support seats 2, and the barbed wire is supported by the wire seat 4, so that the cutter 13 has a supporting force when cutting the barbs of the barbed wire.
[0023] A base 25 is connected to the outer surface of the sleeve 3. A motor 5 is installed on one side of the base 25. The output shaft of the motor 5 is connected with a cam 6. A push rod 7 is arranged inside the base 25. One end of the push rod 7 is connected with a wheel seat 8. The inner wall of the wheel seat 8 is rotatably connected with a roller 9. The outer surface of the roller 9 is in contact with the outer surface of the cam 6. The cam 6 is driven to rotate by the motor 5 as the driving force. When the cam 6 rotates, the push rod 7 is pushed to move its position, and the rotation of the roller 9 in contact with the cam 6 reduces the friction.
[0024] The other end of the push rod 7 is hinged with a first connecting rod 10. The other end of the first connecting rod 10 is threadedly connected with a threaded sleeve 11. The threaded sleeve 11 has the function of adjusting the cutting depth of the cutter 13. By rotating the threaded sleeve 11, the first connecting rod 10 and the second connecting rod 12 are driven to move their positions, changing the supporting position of the cutter 13. The other end of the threaded sleeve 11 is threadedly connected with a second connecting rod 12. The other end of the second connecting rod 12 is hinged with a cutter 13, and the cutter 13 is located above the wire seat 4. The push rod 7 drives the cutter 13 to move its position through the first connecting rod 10 and the second connecting rod 12, and while the cutter 13 moves its position, the barbs of the barbed wire are cut.
[0025] A support shaft 14 is connected to the outer side of the cutter 13, and one end of the support shaft 14 is rotatably connected to a guide wheel 15. A guide groove 16 is provided on the inner side of the sleeve 3, and the inner wall of the guide groove 16 contacts the outer surface of the guide wheel 15. The guide groove 16 guides the direction of the guide wheel 15, guides the cutting position of the cutter 13, and maintains the stability of the guide wheel 15.
[0026] The inner wall of the base 25 is connected to a first slide seat 17, and the inner wall of the first slide seat 17 is slidably connected to the outer surface of the push rod 7. The stability of the push rod 7 during movement is maintained by the first slide seat 17. The outer surface of the push rod 7 is connected to a support plate 18. The outside of the push rod 7 is sleeved with a first spring 19, one end of the first spring 19 is connected to one side of the first slide seat 17, and the other end of the first spring 19 is connected to one side of the support plate 18. The push rod 7 receives the elastic pushing force of the first spring 19 through the support plate 18, and is pushed to reset by the first spring 19 after the push rod 7 moves.
[0027] Two support frames 20 are connected to the upper surface of the wire seat 4, and the two support frames 20 are symmetrical. The inner wall of the support frame 20 is slidably connected with a second slide seat 21, and one side of the second slide seat 21 is rotatably connected with a pressure roller 22. The second slide seat 21 has the function of sliding up and down. The support frame 20 maintains the stability of the second slide seat 21 when sliding, and the second slide seat 21 supports the pressure roller 22 to maintain the stability of the pressure roller 22. During the transmission of the barbed wire, the pressure roller 22 applies pressure to it to maintain the stability of the barbed wire during transmission, so as to prevent the barbed wire from leaving the wire seat 4. The upper surface of the second slide seat 21 is connected with a guide rod 23, and the outer side of the guide rod 23 is sleeved with a second spring 24. One end of the second spring 24 is connected to the inner wall of the support frame 20, and the other end of the second spring 24 is connected to the upper surface of the second slide seat 21. The stability of the second spring 24 during elastic movement is maintained by the guide rod 23, and the elastic supporting force provided by the second spring 24 to the second slide seat 21 is always kept in contact with the barbed wire.
[0028] It should be noted that in actual use of the device, the barb wire is first inserted into the sleeve 3, and then the barb wire is placed on the wire seat 4, and then the barb wire is passed through the pressure roller 22 and pulled out from the sleeve 3, and the motor 5 is started. When the motor 5 rotates, the cam 6 is driven to rotate, and then the cam 6 contacts the roller 9 to push the push rod 7 to move. The push rod 7 pushes the first connecting rod 10 and the second connecting rod 12 to move, and the second connecting rod 12 pushes the cutter 13 to cut the barb wire. When the push rod 7 moves, the first spring 19 is compressed by the support plate 18. The compressed first spring 19 provides power for the push rod 7 to reset. When the cutter 13 moves, the guide wheel 15 is driven to rotate in the guide groove 16 through the support shaft 14 to guide the moving direction of the cutter 13.
