[0001] This utility model relates to the field of medical cutting equipment technology, specifically to an automatic winding and cutting equipment for medical biodegradable fibers. Background Technology

[0002] Medical sutures are an indispensable tool in modern surgery. With a long history, they are now divided into two categories: absorbable sutures and non-absorbable sutures. They are mainly used for suturing or ligating human tissues. The required length of medical sutures varies depending on the application site and scenario, and manufacturers offer a variety of length specifications for their sutures.

[0003] Currently, most medical suture manufacturers on the market manually measure and cut the sutures after production. This method is not only prone to contaminating the sutures, but also inefficient. Especially for sutures with high elongation, manual operation is not precise and stable, which makes it impossible to effectively guarantee the length and increases processing costs. Therefore, medical biodegradable fiber automatic winding and cutting equipment is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic winding and cutting device for medical biodegradable fibers, which solves the problem that in the existing technology, after the sutures are prepared, most of them are measured and cut manually. This method is not only prone to contaminating the medical sutures, but also inefficient. Especially for sutures with high elongation, manual operation cannot be precise and stable, which leads to the inability to effectively guarantee the qualified length and increases the processing cost.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic winding and cutting device for medical biodegradable fibers, including a base plate 1, a plurality of connecting rods 101 fixedly connected to the top of the base plate 1, an mounting plate 102 fixedly connected between the tops of the plurality of connecting rods 101, a U-shaped fixing frame 103 fixedly connected to the top of the base plate 1, a transmission component 2 provided at the bottom of the mounting plate 102, a winding component 3 provided at the top of the transmission component 2, a lifting component 4 provided at the top of the base plate 1, and a cutting section between the top and bottom of the fixing frame 103. Cutting component 5 mounts the take-up roller 304 onto the winding component 3. The transmission component 2 drives the take-up roller 304 to automatically wind the thread, eliminating manual contact throughout the process and preventing thread contamination. The motor 205 ensures stable winding, solving the problem of handling high-elongation threads. After winding to the preset length, the lifting component 4 pushes the support platform 402 to precisely align with the thread. The cutting component 5 drives the cutting shears to cut the thread. Mechanical positioning and cutting ensure the length is qualified, reducing costs. Full automation significantly improves efficiency, solves the pain points of traditional manual processing, and ensures product qualification rate.

[0017] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the transmission assembly 2 includes several rotating rods 201, each rotatably mounted between the top and bottom ends of the mounting plate 102. A gear 202 is fixedly connected to the bottom end of each rotating rod 201. A support rod 203 is fixedly connected to the bottom end of the mounting plate 102, and a support plate 204 is fixedly connected to the bottom end of the support rod 203. A motor 205 is fixedly mounted on the top end of the support plate 204, and the output end of the motor 205 is connected to the shaft end of one of the gears 202. The winding assembly 3 includes several mounting rods 3. 01. Each mounting rod 301 is fixedly connected to the top of each rotating rod 201. A circular chuck 302 is fixedly connected to the outer end of each mounting rod 301. A slot is opened at the top of each chuck 302. A screw hole 303 is opened at the bottom of the inner part of each slot. A take-up roller 304 is sleeved on the outer end of each mounting rod 301. The bottom end of each take-up roller 304 is inserted into the slot. A bolt 305 is threaded between the top of each take-up roller 304 and the inside of the screw hole 303.

[0018] During implementation, the take-up roller 304 is fitted onto the outer end of the mounting rod 301, with the bottom end of the take-up roller 304 inserted into the slot at the top of the chuck 302. Then, the bolt 305 is screwed from the top of the take-up roller 304 into the threaded hole 303 at the bottom of the slot, securing the take-up roller 304 firmly to the mounting rod 301 through the threaded connection. This prevents the take-up roller 304 from shifting during winding, which could lead to uneven thread winding and lays the foundation for subsequent precise winding. Subsequently, the transmission assembly 2 is activated to drive the winding assembly 3 to wind the thread. The mounting plate... The motor 205 on the bottom support plate 204 of 102 is energized and operates. Its output end drives the gear 202 connected to it to rotate. This gear 202 drives the gears 202 at the bottom of the other rotating rods 201 to rotate synchronously through meshing transmission. The rotating rods 201 then rotate smoothly between the top and bottom of the mounting plate 102. The mounting rod 301 fixed at the top of the rotating rod 201 and the take-up roller 304 rotate synchronously with the rotating rod 201, automatically winding the medical biodegradable fiber suture onto the take-up roller 304. The entire winding process does not require manual contact with the suture, completely avoiding the problem of hand contamination of the suture during manual measurement. At the same time, the uniform rotation driven by the motor 205 ensures stable winding tension, solving the problem of unstable operation when manually winding sutures with high elongation.

[0019] As one implementation method in this embodiment, such as Figure 3As shown, the lifting assembly 4 includes an electric push rod 401, which is fixedly installed on the top of the base plate 1. A support 402 is installed on the telescopic end of the electric push rod 401. A cutting groove 403 is horizontally opened on the top of the support 402. A slider 404 is fixedly connected to both the left and right sides of the support 402. The cutting assembly 5 includes an electric push rod 501, which is fixedly installed on the top of the fixing frame 103. A connecting plate 502 is installed on the telescopic end of the electric push rod 501. A slider 504 is fixedly connected to both the left and right sides of the connecting plate 502. A cutter 503 is fixedly connected to the bottom of the connecting plate 502. A sliding groove 104 is opened on both the left and right sides of the fixing frame 103. Each slider 404 and each slider 504 are slidably connected in the sliding groove 104.

[0020] During implementation, the lifting assembly 4 is activated to adjust the cutting position. The telescopic end of the electric push rod 401 at the top of the base plate 1 pushes the support platform 402 upward. The sliders 404 on the left and right sides of the support platform 402 slide smoothly along the grooves 104 on the side of the fixed frame 103, providing vertical guidance for the support platform 402, until the cutting groove 403 at the top of the support platform 402 is aligned with the sewing thread on the take-up roller 304, and the sewing thread just overlaps the cutting groove 403, achieving precise positioning of the sewing thread and avoiding manual positioning. The length deviation is precisely controlled, ensuring the thread length meets specifications and reducing processing costs caused by length discrepancies. Finally, the cutting assembly 5 is activated to complete the automatic cutting. The telescopic end of the electric push rod 501 at the top of the fixing frame 103 pushes the connecting plate 502 downwards. The sliders 504 on the left and right sides of the connecting plate 502 slide along the groove 104, ensuring the connecting plate 502 moves vertically downwards. The cutting scissors 503 fixed at the bottom of the connecting plate 502 also move downwards, precisely cutting into the cutting groove 403 to cut the thread. The cutting process is completed automatically by the mechanical structure, eliminating the need for manual pulling of the thread. This not only significantly improves cutting efficiency but also avoids the stretching and deformation of high-elongation threads caused by manual operation, further ensuring the accuracy of the thread length after cutting.

[0021] Working principle: When this medical biodegradable fiber automatic winding and cutting equipment is working, the winding assembly 3 is assembled first. The take-up roller 304 is placed on the outer end of the mounting rod 301, so that the bottom end of the take-up roller 304 is inserted into the slot at the top of the chuck 302. Then, the bolt 305 is screwed from the top of the take-up roller 304 into the screw hole 303 at the bottom of the slot. The take-up roller 304 is firmly fixed on the mounting rod 301 through the threaded connection, which avoids the take-up roller 304 from shifting during winding, resulting in uneven thread winding and laying the foundation for subsequent accurate winding.

[0022] Subsequently, the transmission assembly 2 is activated to drive the winding assembly 3 to wind the thread. The motor 205 on the bottom support plate 204 of the mounting plate 102 is powered on and operates. Its output end drives the gear 202 connected to it to rotate. This gear 202 drives the gears 202 at the bottom of the other rotating rods 201 to rotate synchronously through meshing transmission. The rotating rods 201 then rotate smoothly between the top and bottom of the mounting plate 102. The mounting rod 301 fixed at the top of the rotating rod 201 and the take-up roller 304 rotate synchronously with the rotating rod 201, automatically winding the medical biodegradable fiber suture onto the take-up roller 304. The entire winding process does not require manual contact with the suture, completely avoiding the problem of hand contamination of the suture during manual measurement. At the same time, the uniform rotation driven by the motor 205 ensures stable winding tension, solving the problem of unstable operation when manually winding sutures with high elongation.

[0023] After the take-up roller 304 winds the thread to the preset length, the lifting assembly 4 is activated to adjust the cutting position. The telescopic end of the electric push rod 401 at the top of the base plate 1 pushes the support 402 upward. The sliders 404 on the left and right sides of the support 402 slide smoothly along the grooves 104 on the side of the fixed frame 103, providing vertical guidance for the support 402 until the cutting groove 403 at the top of the support 402 is aligned with the thread on the take-up roller 304, and the thread just overlaps the cutting groove 403. This achieves precise positioning of the thread, avoids length deviation caused by manual hand positioning, effectively ensures that the thread length is qualified, and reduces processing costs caused by unqualified length.

[0024] Finally, the cutting assembly 5 is activated to complete the automatic cutting. The telescopic end of the electric push rod 501 at the top of the fixing frame 103 pushes the connecting plate 502 downward. The sliders 504 on the left and right sides of the connecting plate 502 slide along the groove 104, ensuring that the connecting plate 502 moves vertically downward. The cutting scissors 503 fixed at the bottom of the connecting plate 502 also move downward, accurately cutting into the cutting groove 403 to cut the thread. The cutting process is completed automatically by the mechanical structure, eliminating the need for manual pulling of the thread. This not only greatly improves cutting efficiency but also avoids the stretching and deformation of the thread with a high elongation rate caused by manual operation, further ensuring the accuracy of the thread length after cutting.

[0025] After cutting, electric push rod 401 drives the support 402 to reset, and electric push rod 501 drives the cutting scissors 503 to reset. A new take-up roller 304 can be quickly replaced for the next round of winding and cutting. The whole process is automated, which not only eliminates the risk of contamination caused by manual contact, but also ensures the consistency of the stitch length through mechanical transmission and positioning, significantly improving production efficiency and product qualification rate.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
