Description

Technical Field

[0001] This invention relates to the field of sterilization equipment, and particularly to a sterilization apparatus and method for suture production. Background Technology

[0002] Medical sutures are common linear materials widely used in various surgical procedures to close wounds and connect tissues. With the continuous advancement of science and technology, suture materials have undergone four generations of development: the first generation was silk suture, the second generation was catgut suture, the third generation was chemically synthesized absorbable sutures (PGA, PGLA, PLA), and the fourth generation is collagen absorbable sutures.

[0003] The fourth generation is a collagen absorbable suture. In the existing suture spinning process, a certain ratio of chitosan, collagen, and sesame oil materials are used to produce nine nascent filaments with a diameter of about 0.01 mm through a spinneret controlled by an ultra-fine filament diameter closed-loop control system. The nascent filaments undergo a double diffusion process between a coagulation bath and a coagulation liquid (acetone, ammonia, etc.) to form finished filaments. Then, they are twisted and untwisted by a false twisting mechanism to form the original suture. After cross-linking treatment to increase its strength and adjust its hydrophilicity, it becomes a medium suture with a certain diameter and strength after appropriate chemical treatment, cleaning, and drying. It is then fed into a winding mechanism with micro-tension control by a winding mechanism to complete the winding of the finished suture.

[0004] Gelatin is made from collagen, a protein found in animal skin and bones. Its main component is protein; it is a pale yellow, transparent, and odorless gelatin. Currently, gelatin is made by boiling collagen, a protein found in the skin, hooves, connective tissue, and bones of animals. Collagen is a biological macromolecule, a major component of animal connective tissue, and the most abundant and widely distributed functional protein in mammals, accounting for 25%–30% of total protein, and even more than 80% in some organisms.

[0005] The raw materials needed to produce collagen sutures need to be cleaned before processing. Most sterilization equipment can only perform sterilization and cannot clean. However, after cleaning, sterilization is achieved by introducing steam, making it difficult to sterilize the materials at the same time as cleaning. This makes the processing steps complicated and affects the processing efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a sterilization device and method for suture production to solve the above-mentioned problems, thereby improving the problem that sterilization is achieved by steam injection after cleaning, which makes it difficult to sterilize materials at the same time as cleaning, and the processing steps are complicated and affect processing efficiency.

[0007] The present invention achieves the above-mentioned objective through the following technical solution: a sterilization device for suture production, comprising: a shell, wherein a servo motor is installed at the upper end of the shell; a sterilization mechanism, wherein the sterilization mechanism is installed inside the shell, and the surface of the sterilization mechanism extends to the outside of the shell; wherein the sterilization mechanism includes a cleaning component for cleaning and removing impurities from materials, the cleaning component is installed inside the shell, a lower sterilization seat is connected to the lower end of the cleaning component, the lower sterilization seat extends to the outside of the shell, a crushing component is disposed inside the cleaning component, the surface of the crushing component extends to the inside of the lower sterilization seat, the crushing component is used to assist in crushing the materials, and a centrifugal component is installed inside the lower sterilization seat, the centrifugal component is used to heat the materials.

[0008] Preferably, the cleaning assembly includes an upper sterilization seat fixedly connected to the inner wall of the outer shell. The upper sterilization seat has an internal circular cavity. A side liquid storage tank is formed on one side of the upper sterilization seat. A rotating column, rotatably connected to the inner wall of the outer shell, is disposed inside the internal circular cavity. A shaped blade is fixedly connected to the surface of the rotating column. An arc-shaped filter plate is disposed between the internal circular cavity and the side liquid storage tank. An impurity storage box is fixedly connected to the inner wall of the side liquid storage tank. An impurity filter cloth is connected to the inner wall of the impurity storage box, and the impurity filter cloth contacts the lower arc surface of the arc-shaped filter plate. A pump body is fixedly connected to the inner bottom wall of the side liquid storage tank. A conduit is connected to the outlet of the pump body, and a nozzle is installed at the other end of the conduit. Driving the pump body causes it to spray the warm liquid inside the side liquid storage tank through the conduit and out through the nozzle. The sprayed liquid can combine with ozone for sterilization. A drain valve is provided on the inner wall of the side liquid storage tank, and an inlet pipe is connected to the inside of the side liquid storage tank.

[0009] Preferably, the compaction assembly includes a guide chamber located inside the upper sterilization seat and an internal compaction chamber located inside the lower sterilization seat. An electric push rod is fixedly connected to the outer shell surface inside the guide chamber. The telescopic end of the electric push rod extends into the guide chamber and is fixedly connected to an arc-shaped sealing plate. A central connecting pipe connects the guide chamber and the internal compaction chamber. A rotating rod is installed on the inner wall of the central connecting pipe, and a conical truncated cone is fixedly connected to the surface of the rotating rod. The electric push rod drives the arc-shaped sealing plate to close and open the guide chamber. Simultaneously, a rubber sealing ring is provided on the surface of the arc-shaped sealing plate to ensure a water-tight effect. When the rotating rod rotates, it will cause the conical truncated cone to rotate accordingly.

[0010] Preferably, the centrifuge assembly includes a cylindrical chamber and a heating chamber located inside the lower sterilization chamber. The heating chamber is connected to the cylindrical chamber and the internal crushing chamber. A telescopic sliding seat is slidably connected to the inner bottom wall of the heating chamber. Multiple ball bearings are installed on the inner bottom wall of the telescopic sliding seat. A rotating cylinder is positioned above the telescopic sliding seat. A square shaft is provided on the inner wall of the cylindrical chamber. A rotating shaft is fixedly connected to the upper end of the square shaft and is fixedly connected to the output shaft of a servo motor. When the rotating cylinder rotates, the ball bearings on the inner bottom wall of the telescopic sliding seat ensure the smooth movement of the rotating cylinder. {The mounting base for the ball bearings on the inner bottom wall of the telescopic sliding seat is separable and telescopic, but can also be replaced with a hinged opening mechanism, etc., depending on the actual situation.}

[0011] Preferably, a crescent-shaped mounting plate is fixedly connected to the inner wall of the internal circular cavity. The inner side of the crescent-shaped mounting plate is in contact with the surface of the shaped blade, and an arc-shaped groove is formed on the inner side of the crescent-shaped mounting plate. {The shaped blade is curved in the middle to form a “”-shaped bend, giving it an overall eaves-like shape. The ridge line is curved into an arc shape, and water-permeable holes are formed on the surface of the shaped blade.} At this time, the shaped blade will rotate around the rotating column as the axis of rotation.

[0012] Preferably, one end of the rotating column extends through to the outside of the housing and is fixedly connected to a first one-way bearing, the outer edge of which is fixedly connected to a worm gear. The rotating shaft drives the worm to rotate, which in turn drives the worm gear meshing with it to follow suit. When the worm gear moves, it drives the rotating column to rotate synchronously via the first one-way bearing.

[0013] Preferably, a fixed abutment is fixedly connected to the inner wall of the internal crushing chamber, and an internal groove is formed inside the conical truncated cone. A movable crushing block is slidably connected to the inner wall of the internal groove, and a spring is installed on the side of the movable crushing block near the internal groove. The fixed abutment on the inner wall of the internal crushing chamber allows the movable crushing block to cooperate with the fixed abutment to form a gap through which material can pass. At this time, the movable crushing block and the fixed abutment abut against each other, causing the movable crushing block to contract towards the internal groove while simultaneously squeezing the spring. As the conical truncated cone continues to rotate, the movable crushing block will become misaligned with the fixed abutment. Under the reset action of the spring, the movable crushing block will move towards the inner wall of the internal crushing chamber. At this point, the gap allowing material to pass disappears, and the material will be squeezed by the movable crushing block, thus undergoing initial crushing to aid in subsequent cooking steps.

[0014] Preferably, the upper end of the rotating rod extends through the central connecting pipe and is fixedly connected to a second one-way bearing, while the lower end of the rotating rod extends into the interior of the internal crushing chamber and is fixedly connected to a bottom scraper. A servo motor is driven to rotate forward, causing the pulley on the surface of the rotating rod to rotate synchronously, at which point the second one-way bearing will idle.

[0015] Preferably, a bottom round rod is fixedly connected to the inner wall of the rotating cylinder, and a top locking block is fixedly connected to the upper end of the bottom round rod. The lower end of the bottom round rod extends through the interior of the telescopic sliding seat. An internal partition is installed on the inner wall of the rotating cylinder, and a square hole sliding sleeve is slidably connected to the surface of the square shaft. The square hole sliding sleeve matches the top locking block. The top locking block rotates synchronously through the square hole sliding sleeve. The upper end of the top locking block can be set to be conical. In this case, the top locking block will drive the rotating cylinder to rotate synchronously through the bottom round rod, which will cause the rotating cylinder to drive the internal partition to rotate synchronously as well. At this time, the rotating cylinder contains materials and some liquid. Under the drive of the internal partition, the liquid will rotate with the rotating cylinder, thereby completing the centrifugation operation.

[0016] Preferably, a worm gear meshing with a worm wheel is fixedly connected to the surface of the rotating shaft, and pulleys are fixedly connected to the surfaces of both the rotating shaft and the rotating rod. A transmission belt is fitted onto the surfaces of the two pulleys. When the servo motor rotates forward, the rotating shaft will rotate accordingly, causing the worm gear to drive the worm wheel to work synchronously. At this time, the rotating shaft will drive the first one-way bearing to rotate freely, and the pulley on the surface of the synchronous rotating shaft will drive the pulley on the surface of the rotating rod to rotate synchronously via the transmission belt. At this time, the second one-way bearing will rotate freely.

[0017] A method for producing sutures;

[0018] A1. First, warm water is injected into the side storage tank through the inlet pipe. Then, the pump body is driven to work, and ozone is injected into the inner cavity. Ozone can also be continuously injected through an external pipe as needed. When ozone is injected into the inner cavity, the nozzle will spray liquid to contact with the ozone for sterilization. At the same time, materials such as animal connective tissue are put in. When the liquid sprayed from the nozzle comes into contact with the ozone, it impacts the shaped blades and moves. At the same time, the shaped blades move the liquid in contact with the ozone, and the liquid will sterilize the materials. When the shaped blades move, they will turn the materials, thereby completing the cleaning and preliminary sterilization of the materials and removing some impurities from the materials.

[0019] A2. After the cleaning and preliminary sterilization operations are completed, the clean sterile liquid can be replaced. After a period of sedimentation, the material is located at the bottom of the inner wall of the internal circular cavity. The servo motor is operated in reverse, which will drive the rotating column and rotating rod to move synchronously. Then, the rotating column will drive the shaped blade to rotate in reverse, driving the electric push rod to drive the arc-shaped sealing plate to open the feed port of the guide chamber. At this time, the shaped blade will guide the sedimented material into the guide chamber and then into the internal crushing chamber. The rotating rod drives the conical truncated cone to perform preliminary crushing of the material, which is convenient for the subsequent cooking of the material. Afterwards, the material is guided to the heating chamber for centrifugation.

[0020] A3. Place the rotating cylinder on the inner bottom wall of the telescopic sliding seat, and insert the lower end of the bottom round rod into the telescopic sliding seat. At this time, the rotating cylinder will be above the ball bearings. Simultaneously, place the telescopic sliding seat into the heating chamber. This will cause the top locking block at the upper end of the bottom round rod to contact the lower arc-shaped surface of the square hole sliding sleeve. The abutting arc-shaped surface will cause the top locking block to engage with the square hole sliding sleeve. Then, as the square shaft rotates, the bottom round rod will rotate synchronously through the cooperation of the square hole sliding sleeve and the top locking block. This will cause the rotating cylinder to centrifuge the internal material through the internal partition. At the same time, the heating plate installed on the inner wall of the heating chamber can assist in the steaming operation of the material inside the rotating cylinder, and perform secondary sterilization of the material.

[0021] The beneficial effects of this invention are:

[0022] 1. During operation, the cleaning component can clean the materials fed into the machine and remove some impurities, reducing their impact. Simultaneously, it uses ozone to sterilize the materials. Compared to existing equipment that uses steam for sterilization after cleaning, which is difficult to sterilize simultaneously and involves complex processing steps that affect efficiency, this device removes some impurities during the cleaning process and uses ozone for preliminary sterilization. This allows for sterilization during cleaning, shortening processing steps and improving efficiency.

[0023] 2. During operation, the crushing assembly assists in crushing materials after initial sterilization. The device uses a second one-way bearing to drive a rotating rod, which in turn rotates the conical truncated cone. This rotation of the cone causes the movable crushing block to rotate synchronously. Material falling onto the top of the cone is then propelled towards its conical surface by centrifugal force. Simultaneously, the inner wall of the crushing chamber is equipped with fixed blocks that, when the cone rotates, cause the movable crushing block to... The crushing block, together with the fixed abutment block, will create a gap through which the material can pass. At this time, the moving crushing block and the fixed abutment block will abut against each other, causing the moving crushing block to contract into the inner groove while squeezing the spring sheet. As the conical truncated cone continues to rotate, the moving crushing block will be misaligned with the fixed abutment block. At this time, the moving crushing block will move towards the inner wall of the inner crushing chamber under the reset action of the spring sheet. At this time, the gap that allows the material to pass through will disappear, and the material will be squeezed by the moving crushing block. At this time, the material will be initially crushed to assist the subsequent cooking steps.

[0024] 3. The crushed material will be cooked in the heating chamber, and centrifugation can be performed at the same time. This method allows some impurities to be released during the heating process. At this time, under the action of centrifugation, the impurities and cooking products will be separated into different areas, which will help the operators to process and extract them. At the same time, the cooking process will sterilize the material a second time. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In practical implementation: such as Figure 1-11 As shown, a sterilization device for suture production includes: a housing 1, with a servo motor 2 mounted on the upper end of the housing 1; and a sterilization mechanism 3, which is installed inside the housing 1 and has its surface extending to the outside of the housing 1.

[0039] The sterilization mechanism 3 includes a cleaning component 31 for cleaning and removing impurities from materials. The cleaning component 31 is installed inside the outer shell 1. The lower end of the cleaning component 31 is connected to a lower sterilization seat 34, which extends to the outside of the outer shell 1. A crushing component 32 is installed inside the cleaning component 31. The surface of the crushing component 32 extends into the interior of the lower sterilization seat 34. The crushing component 32 is used to assist in crushing the materials. A centrifugal component 33 is installed inside the lower sterilization seat 34. The centrifugal component 33 is used to heat the materials.

[0040] By feeding materials into the cleaning component 31, the cleaning component 31 will remove impurities and clean the materials during operation. After cleaning, the cleaning component 31 will reverse its movement driven by the servo motor 2. At this time, the crushing component 32 will work, and the materials inside the cleaning component 31 will be introduced into the crushing component 32. Then, when the servo motor 2 is working, the crushing component 32 will be driven by the centrifugal component 33 to perform preliminary crushing and crushing of the materials inside. In subsequent material feeding processes, liquid and materials will be introduced into the centrifugal component 33 for processing and centrifugation. During the cooking process, the materials will be softened by the centrifugal component 33. The softened materials will be centrifuged by the centrifugal component 33, separating the internal impurities from the softened materials, making it easier for operators to obtain materials for auxiliary processing.

[0041] like Figures 1-9 As shown, the cleaning assembly 31 includes an upper sterilization seat 311 fixedly connected to the inner wall of the outer shell 1. The upper sterilization seat 311 has an internal circular cavity 312. A side liquid storage tank 313 is provided on one side of the upper sterilization seat 311. A rotating column 314 rotatably connected to the inner wall of the outer shell 1 is disposed inside the internal circular cavity 312. A shaped blade 315 is fixedly connected to the surface of the rotating column 314. An arc-shaped filter plate 316 is disposed between the internal circular cavity 312 and the side liquid storage tank 313. An impurity storage box 3110 is fixedly connected to the inner wall of the side liquid storage tank 313. An impurity filter cloth 3111 is connected to the inner wall of the impurity storage box 3110. 111 contacts the lower arc surface of the arc-shaped filter plate 316. The inner bottom wall of the side liquid storage tank 313 is fixedly connected to the pump body 317. The outlet of the pump body 317 is connected to the conduit 318. The other end of the conduit 318 is equipped with a nozzle 319. The inner wall of the internal circular cavity 312 is fixedly connected to the crescent mounting plate 3112. The inner side of the crescent mounting plate 3112 contacts the surface of the irregular blade plate 315. The inner side of the crescent mounting plate 3112 is provided with an arc groove 3113. One end of the rotating column 314 extends to the outside of the outer shell 1 and is fixedly connected to the first one-way bearing 3115. The outer edge of the first one-way bearing 3115 is fixedly connected to the worm gear 3114.

[0042] Material is fed into the inner cavity 312 through the material inlet at the upper end of the upper sterilization seat 311. Ozone can be installed inside the inner cavity 312. The pump 317 is then driven to pump the warm liquid inside the side liquid storage tank 313, guided by the conduit 318, and sprayed out through the nozzle 319. A drain valve is provided on the inner wall of the side liquid storage tank 313, and a water inlet pipe is connected inside the side liquid storage tank 313. The nozzle 319 then sprays the liquid onto the inner wall of the arc-shaped groove 3113. The inner wall of 3113 guides the fluid to flow towards the crescent mounting plate 3112 and impact the irregular blade plate 315 {the irregular blade plate 315 is curved in the middle with a "7" shaped bend, and the whole shape is like an eaves. The ridge line is curved into an arc. Water-permeable holes are opened on the surface of the irregular blade plate 315}. At this time, the irregular blade plate 315 will rotate around the rotating column 314 as the axis of rotation {at the same time, the liquid level in the upper sterilization seat 311 needs to be maintained between the highest point of the water inlet area of ​​the arc-shaped filter plate 316 and the highest point of the impurity filter cloth 3111}.

[0043] When the fluid impacts the shaped impeller 315, the ridge end of the shaped impeller 315 away from the rotating column 314 will agitate the material inside the liquid. Simultaneously, at the end of the shaped impeller 315 away from the rotating column 314, the material will be guided to both sides in the fluid. This agitation and dispersion will cause the material to move towards the arc-shaped filter plate 316, where it will intercept the material. Meanwhile, impurities in the material will pass through the arc-shaped filter plate 316 {larger impurities will be removed before input, while smaller impurities will be agitated by the water flow and easily pass through the arc-shaped filter plate 316}. The side storage tank 313 is connected to the internal circular cavity 312. When the pump body 317 is working, the side storage tank 313 will... The water flow is always directed outwards. When the pump body 317 is working, the water flow will always flow from the internal circular cavity 312 to the side liquid storage tank 313. At this time, the water flow will carry impurities to wash the impurity filter cloth 3111. Since the upper arc-shaped part of the impurity filter cloth 3111 is not supported, it will bend downwards under the impact of the water flow. Then the impurities will enter the impurity temporary storage box 3110. After that, the water flow will carry the impurities towards the pump body 317. At this time, it will be intercepted by the horizontal part of the impurity filter cloth 3111. Then the impurities will be retained inside the impurity temporary storage box 3110. Under the combined action of water flow, gravity and the bending part of the impurity filter cloth 3111, the impurities will be reduced and flow back to the internal circular cavity 312. This allows the impurities in the material to be gradually collected by the impurity temporary storage box 3110, ensuring that the internal impurities are removed when the material is cleaned and sterilized.

[0044] After the internal cavity 312 has been cleaned and sterilized, the pump body 317 can be stopped, and the servo motor 2 can be reversed. This reverse rotation of the servo motor 2 will drive the worm gear 3313 to rotate via the rotating shaft 3314, which in turn will drive the meshing worm wheel 3114 to follow suit. When the worm wheel 3114 rotates, it will drive the rotating column 314 to rotate synchronously via the first one-way bearing 3115. This rotating column 314 will then drive the shaped blade 315 to rotate in reverse. At this time, the end of the shaped blade 315 away from the rotating column 314 will agitate the material settled at the bottom of the internal cavity 312. Simultaneously, the end of the shaped blade 315 away from the rotating column 314 will gather the material in the middle area of ​​the shaped blade 315. Furthermore, because the shaped blade 315 is curved at its ridge, and... When the end of the shaped blade 315 away from the rotating column 314 contacts the inner wall of the crescent mounting plate 3112, the material will move along the inner wall of the crescent mounting plate 3112 when it is pushed. At this time, the electric push rod 322 can be driven to move the arc-shaped closed plate 323, so that the guide chamber 321 is connected to the inner cavity 312. Then, the material will enter the interior of the guide chamber 321 under the guidance of the shaped blade 315. The opening shape of the guide chamber 321 matches the end section of the shaped blade 315. At the same time, if the shaped blade 315 pushes too much material, the material will not be able to completely enter the guide chamber 321. At this time, since the end of the shaped blade 315 does not contact the inner wall of the arc groove 3113, the material will no longer be supported and will slide down along the inner wall of the crescent mounting plate 3112 under gravity. It will be pushed into the guide chamber 321 again by the adjacent shaped blade 315.

[0045] The compaction assembly 32 includes a guide chamber 321 located inside the upper sterilization seat 311 and an internal compaction chamber 326 located inside the lower sterilization seat 34. An electric push rod 322 is fixedly connected to the surface of the outer shell 1 inside the guide chamber 321. The telescopic end of the electric push rod 322 extends into the interior of the guide chamber 321 and is fixedly connected to an arc-shaped sealing plate 323. A central connecting pipe 324 connects the guide chamber 321 and the internal compaction chamber 326. A rotating rod 325 is installed on the inner wall of the central connecting pipe 324, and a cone is fixedly connected to the surface of the rotating rod 325. The cone-shaped truncated cone 328 has a fixed abutment 327 fixedly connected to the inner wall of the inner compaction chamber 326. The cone-shaped truncated cone 328 has an inner groove 3210. A movable compaction block 3212 is slidably connected to the inner wall of the inner groove 3210. A spring piece 3211 is installed on the side of the movable compaction block 3212 near the inner groove 3210. The upper end of the rotating rod 325 passes through the middle connecting pipe 324 and is fixedly connected to the second one-way bearing 3213. The lower end of the rotating rod 325 passes through the interior of the inner compaction chamber 326 and is fixedly connected to the bottom scraper 329.

[0046] The electric push rod 322 drives the arc-shaped sealing plate 323 to close and open the guide chamber 321. Simultaneously, a rubber sealing ring is provided on the surface of the arc-shaped sealing plate 323 to ensure water tightness. When the centrifugal assembly 33 is working, the second one-way bearing 3213 drives the rotating rod 325 to rotate. The rotating rod 325, in turn, drives the conical truncated cone 328 to rotate. This rotation of the conical truncated cone 328 causes the movable crushing block 3212 to rotate synchronously. Material falling onto the conical truncated cone 328 will move towards its conical arc surface under centrifugal force. Meanwhile, the inner wall of the internal crushing chamber 326 is equipped with a fixed abutment 327. When the conical truncated cone 328 rotates, the movable crushing block 3212, in conjunction with the fixed abutment 327, will allow the material to pass through. During the gap, the movable crushing block 3212 and the fixed abutment block 327 abut against each other, causing the movable crushing block 3212 to contract into the inner groove 3210 while squeezing the spring sheet 3211. When the conical truncated cone 328 continues to rotate, the movable crushing block 3212 will be misaligned with the fixed abutment block 327. At this time, the movable crushing block 3212 will move towards the inner wall of the inner crushing chamber 326 under the reset action of the spring sheet 3211. At this time, the gap that allows the material to pass through disappears, and the material will be squeezed by the movable crushing block 3212. At this time, the material will be initially crushed to assist the subsequent cooking steps. When the conical truncated cone 328 continues to move, the gap will be formed again. Impacted by the water flow above, the crushed material will impact the inner bottom wall of the inner crushing chamber 326 and then be pushed into the interior of the heating chamber 333 by the bottom scraper 329.

[0047] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 10 , Figure 11As shown, the centrifuge assembly 33 includes a cylindrical chamber 332 and a heating chamber 333 located inside the lower sterilization seat 34. The heating chamber 333 is connected to the cylindrical chamber 332 and the internal crushing chamber 326. A telescopic sliding seat 334 is slidably connected to the inner bottom wall of the heating chamber 333. Multiple ball bearings 335 are installed on the inner bottom wall of the telescopic sliding seat 334. A rotating cylinder 336 is arranged above the telescopic sliding seat 334. A square shaft 331 is arranged on the inner wall of the cylindrical chamber 332. A rotating shaft 3314 is fixedly connected to the upper end of the square shaft 331. The rotating shaft 3314 is fixedly connected to the output shaft of the servo motor 2. A bottom round rod 337 is fixedly connected to the inner wall of the rotating cylinder 336. A top locking block 339 is fixedly connected to the upper end of the bottom round rod 337. The lower end of the bottom round rod 337 extends into the interior of the telescopic sliding seat 334. An internal partition 338 is installed on the inner wall of the rotating cylinder 336. A square hole sliding sleeve 3310 is slidably connected to the surface of the square shaft 331. The square hole sliding sleeve 3310 matches the top locking block 339. A worm 3313 that meshes with the worm gear 3114 is fixedly connected to the surface of the rotating shaft 3314. Pulleys 3311 are fixedly connected to the surfaces of both the rotating shaft 3314 and the rotating rod 325. A transmission belt 3312 is sleeved on the surfaces of the two pulleys 3311 to drive the servo motor 2 to rotate forward. At this time, the rotating shaft 3314 will rotate accordingly, which will cause the worm 3313 to drive the worm gear 3114 to work synchronously. 314 will cause the first one-way bearing 3115 to rotate idling. The pulley 3311 on the surface of the synchronous rotating shaft 3314 will drive the pulley 3311 on the surface of the rotating rod 325 to rotate synchronously via the transmission belt 3312. At this time, the second one-way bearing 3213 will rotate idling, and the square shaft 331 will rotate synchronously with the rotating shaft 3314. In turn, the square shaft 331 will drive the square hole sliding sleeve 3310 to rotate synchronously. The square hole sliding sleeve 3310 will drive the top locking block 339 to rotate synchronously. The upper end of the top locking block 339 can be set as conical. At this time, the top locking block 339 will drive the rotating cylinder 336 to rotate synchronously via the bottom round rod 337, thereby causing the rotating cylinder 336 to rotate synchronously. The cylinder 336 will drive the internal partition 338 to rotate synchronously. At this time, the inside of the rotating cylinder 336 contains materials and some liquid. Under the drive of the internal partition 338, the liquid will rotate with the rotating cylinder 336 to complete the centrifugation operation. At this time, the material with more impurities will be close to the inner wall of the rotating cylinder 336, while the material with fewer impurities will remain in the central area of ​​the rotating cylinder 336. When the rotating cylinder 336 rotates, the ball bearings 335 on the bottom wall of the telescopic sliding seat 334 ensure the smooth movement of the rotating cylinder 336. {The mounting seat of the ball bearings 335 on the bottom wall of the telescopic sliding seat 334 is separate and telescopic, and can also be replaced with a hinged opening method according to the actual situation}.

[0048] A method for producing sutures;

[0049] A1. First, warm water is injected into the side storage tank 313 through the inlet pipe. Then, the pump body 317 is driven to work, and ozone is injected into the inner cavity 312. Ozone can also be continuously injected through an external pipe as needed. When ozone is injected into the inner cavity 312, the nozzle 319 will spray out liquid to contact with ozone for sterilization. At the same time, materials such as animal connective tissue are put in. When the liquid sprayed out by the nozzle 319 comes into contact with ozone, it impacts the shaped blade 315 and moves. At the same time, the shaped blade 315 moves the liquid in contact with ozone, and the liquid will sterilize the materials. When the shaped blade 315 moves, it will turn the materials to complete the cleaning and preliminary sterilization of the materials, and remove some impurities from the materials.

[0050] A2. After the cleaning and preliminary sterilization operations are completed, the clean sterile liquid can be replaced. After a period of sedimentation, the material is located at the bottom of the inner wall of the internal circular cavity 312. The servo motor 2 is operated in reverse, which will drive the rotating column 314 and the rotating rod 325 to move synchronously. Then, the rotating column 314 will drive the shaped blade 315 to rotate in reverse, driving the electric push rod 322 to drive the arc-shaped sealing plate 323 to open the feed port of the guide chamber 321. At this time, the shaped blade 315 will guide the sedimented material into the guide chamber 321 and then into the internal crushing chamber 326. The rotating rod 325 drives the conical frustum 328 to perform preliminary crushing of the material, which is convenient for the subsequent cooking of the material. Afterwards, the material is guided to the heating chamber 333 for centrifugation.

[0051] A3. Place the rotating cylinder 336 on the inner bottom wall of the telescopic sliding seat 334, and insert the lower end of the bottom round rod 337 into the telescopic sliding seat 334. At this time, the rotating cylinder 336 will be above the ball bearing 335. Simultaneously, place the telescopic sliding seat 334 into the heating chamber 333. This will cause the top locking block 339 at the upper end of the bottom round rod 337 to contact the lower arc-shaped surface of the square hole sliding sleeve 3310. The abutting arc-shaped surface will cause the top locking block 339 to engage with the square hole sliding sleeve 3310. Then, as the square shaft 331 rotates, the bottom round rod 337 will rotate synchronously through the cooperation of the square hole sliding sleeve 3310 and the top locking block 339. This will cause the rotating cylinder 336 to centrifuge the internal material through the internal partition 338. At the same time, the heating plate on the inner wall of the heating chamber 333 can assist in the steaming operation of the material inside the rotating cylinder 336, and perform secondary sterilization of the material.

[0052] In use, the material is fed into the internal circular cavity 312. The pump body 317 drives the warm liquid inside the side storage tank 313 through the conduit 318 and sprays it out through the nozzle 319. The guide crescent mounting plate 3112 on the inner wall of the arc-shaped groove 3113 impacts the irregular blade plate 315. The irregular blade plate 315 rotates around the rotating column 314, turning the material over. The material moves towards the arc-shaped filter plate 316, and impurities in the material pass through the arc-shaped filter plate 316. When the pump body 317 is working, the water always flows from the internal circular cavity 312 to the side storage tank 313. The impurities are washed away by the impurity filter cloth 3111 and left in the impurity temporary storage box 3110. After the internal circular cavity 312 is cleaned and sterilized, the pump... When body 317 stops working, it simultaneously drives servo motor 2 to reverse. This reverse rotation of servo motor 2 causes the worm gear 3313 to rotate via rotating shaft 3314, which in turn drives the worm wheel 3114, which meshes with it, to follow suit. During this rotation, the worm wheel 3114 drives rotating column 314 to rotate synchronously via first one-way bearing 3115. Rotating column 314 causes the shaped blade 315 to reverse. The end of the shaped blade 315 furthest from rotating column 314 will move the material at the bottom of the internal cavity 312 along the inner wall of the crescent mounting plate 3112, driving electric push rod 322 to move the arc-shaped sealing plate 323. The guide chamber 321 connects to the internal cavity 312, and material is introduced into the guide chamber 321. The second... One-way bearing 3213 drives rotating rod 325 to rotate, thereby causing conical truncated cone 328 to drive movable crushing block 3212 to rotate synchronously. Material falls onto the conical truncated cone 328 and moves towards the conical arc surface of the conical truncated cone 328 under the action of centrifugal force. At the same time, the inner wall of the internal crushing chamber 326 is provided with fixed abutment block 327. When the conical truncated cone 328 rotates, the movable crushing block 3212 and the fixed abutment block 327 abut against each other to form a gap for material to pass through. The movable crushing block 3212 retracts into the inner groove 3210 and squeezes the spring sheet 3211. When the conical truncated cone 328 continues to rotate, the movable crushing block 3212 and the fixed abutment block 327 are misaligned, and the material is squeezed by the movable crushing block 3212. The truncated cone 328 continues to move, and the gap is formed again. The water flow impacts the crushed material against the bottom wall of the inner crushing chamber 326. It is then pushed into the heating chamber 333 by the bottom scraper 329. The square shaft 331 rotates synchronously with the rotating shaft 3314. The square shaft 331 drives the square hole sliding sleeve 3310 to rotate synchronously. The square hole sliding sleeve 3310 drives the top locking block 339 to rotate synchronously. The upper end of the top locking block 339 is set in a conical shape. The top locking block 339 drives the rotating cylinder 336 to rotate synchronously through the bottom round rod 337. The rotating cylinder 336 drives the internal partition 338 to rotate synchronously. When the rotating cylinder 336 rotates, the ball bearings 335 on the bottom wall of the telescopic sliding seat 334 ensure the smooth movement of the rotating cylinder 336.
