Description

Technical Field

[0001] This invention relates to a high-performance medical metal cable manufacturing platform and preparation method, belonging to the field of medical orthopedic braiding technology. Background Technology

[0002] In the field of orthopedic internal fixation devices, high-performance metal cables made of multi-strand metal wires are gradually replacing traditional steel plates for ligation and fixation of fracture sites. Compared with plate and screw internal fixation, metal cable ligation has clinical advantages such as less trauma and faster postoperative recovery. Currently, the preparation of such high-performance medical metal cables mainly relies on manual braiding or semi-automatic machine-assisted braiding. The basic process involves twisting multiple metal wires layer by layer or in groups to ultimately synthesize a multi-strand metal cable.

[0003] However, the aforementioned preparation methods have revealed shortcomings in both efficiency and quality during actual production. On the one hand, manual twisting and semi-automatic machine operation have a slow production cycle, and the twisting process needs to be completed in multiple segments, making it impossible to achieve one-time forming and twisting of multiple layers of metal wires. The numerous process transfers result in low overall production efficiency, are time-consuming and labor-intensive, and cannot meet the capacity requirements of mass production. On the other hand, manual operation and simple mechanical twisting lack effective guarantees for the tension control, twist pitch uniformity, and interlayer arrangement accuracy of the metal wires. The twisted metal cables are prone to problems such as uneven interstrand gaps, local looseness, or uneven surfaces, directly causing the tensile strength and fatigue life of the products to fail to meet the standards. The appearance quality also fails to meet the strict standards of clinical implantable devices, seriously restricting the consistency of product quality.

[0004] Therefore, there is an urgent need to find an efficient manufacturing method that can achieve one-time forming and twisting of multiple metal wires. This method should be able to uniformly twist multiple layers of metal wires in one process, and ensure the density and surface flatness of the metal cable through reliable tension and twist pitch control. This will significantly improve production efficiency while ensuring that the product has the mechanical strength and appearance quality to meet the requirements of clinical implantation.

[0014] Secondly, the present invention provides a method for preparing a high-performance medical metal cable, using a high-performance medical metal cable fabrication platform, comprising: The core wire is fixed to the take-up and release mechanism at one end, and after being pulled out, it passes through the central core tube of the inner winding mechanism, the central core tube of the middle winding mechanism, and the central core tube of the outer winding mechanism in sequence, and is wound into the groove of the groove wheel of the dual-drive traction machine. Then it is pulled out from the groove of the groove wheel and wound onto the take-up and release mechanism at the other end. The wires on the inner winding mechanism, the middle winding mechanism, and the outer winding mechanism are pulled out and fixed onto the core wire, respectively. Simultaneously, the take-up and release mechanism, the inner winding mechanism, the middle winding mechanism, the outer winding mechanism, and the dual-drive traction machine are activated. The twisting pitch is controlled by the dual-drive traction machine to form a multi-layer spiral structure medical metal cable on the core wire, and the twisted medical metal cable is pulled onto the take-up and release mechanism.

[0015] Advantages and effects of the present invention: This invention addresses the shortcomings of existing medical metal cable manufacturing processes, which rely on manual stranding or semi-automatic machine-assisted operations. These shortcomings include slow production cycles, the need for multiple segmented stranding processes preventing the one-time forming of multi-layered metal wires, and the lack of effective tension control and strand pitch uniformity in manual operations, leading to uneven inter-strand gaps and substandard mechanical properties. Through a systematic structural innovation—a concentric series layout of three winding mechanisms (inner, middle, and outer layers), precise control of the stranding pitch by a dual-drive traction machine, and coordinated linear wire laying by the take-up and unwinding mechanism—this invention constructs an automated manufacturing platform for one-time forming and stranding of multi-stranded metal wires. This fully mechanized operation replaces traditional manual segmented stranding, significantly improving production efficiency while ensuring the density and surface flatness of the metal cable strands through reliable tension and strand pitch control. Specifically, it also includes: 1. The inner, middle, and outer winding mechanisms are coaxially connected in series, enabling continuous stranding of multiple layers of metal wire in a single process: The inner, middle, and outer winding mechanisms are arranged concentrically along the direction of the core wire's travel, with their central core tubes coaxially positioned. After the core wire is pulled out from one end by the take-up and release mechanism, it passes through the central core tubes of each layer in sequence. The wire carriers of each layer simultaneously release the metal wire of the corresponding layer and strand it onto the core wire. This series layout breaks through the limitations of traditional segmented stranding processes that require multiple steps, allowing the inner, middle, and outer metal wires to be continuously stranded in one process, thus solving the core problem of low efficiency in the production of multi-layer metal cables from a process architecture perspective.

[0016] 2. The differential rotation of the multi-layer winding discs and the orientation of the central wire carrier maintain coordination, ensuring the tightness of the interlayer stranding and structural stability: The large and small turntables of the middle layer winding mechanism can be independently driven to perform differential circular motion, while the wire carrier discs of the outer layer winding mechanism and the middle layer wire carrier discs can perform circular motions in opposite directions. The wire carriers on the central wire carrier discs of each layer remain oriented and do not rotate with the turntables, ensuring that the metal wire is not twisted during release. Each layer of wire carriers releases the wire under constant tension, forming a uniform and tight spiral winding structure on the core wire surface. This effectively eliminates the defects of uneven interstrand gaps and localized looseness in traditional manual stranding, ensuring that the mechanical strength and fatigue life of the metal cable meet clinical implantation requirements from both tension and twist control perspectives.

[0017] 3. The dual-drive traction machine and the linear winding mechanism work together to achieve precise control of the twisting pitch and uniform winding of the product: The dual-drive traction machine drives two traction wheels through two sets of reduction motors, one above the other. The center of the first groove of the lower traction wheel is aligned with the center of the wire outlet of the upper traction wheel. The core wire obtains stable traction force under the constraint of the groove of the groove wheel. The twisting pitch is precisely controlled by matching the traction speed and the winding spool speed. The motion module of the winding mechanism performs linear reciprocating motion and works in conjunction with the winding reduction motor to evenly arrange the twisted metal cable on the winding spool, ensuring the winding quality of the product and the convenience of subsequent retrieval.

[0018] 4. Fully automated operation replaces traditional manual segmented stranding, significantly improving production efficiency and product quality consistency: From core wire release, synchronous stranding of multiple layers of metal wires, and pitch control to finished product winding, the entire process is completed automatically by various mechanisms on the frame, completely changing the traditional operation mode that relied on manual layer-by-layer segmented stranding. Production cycle time is greatly increased, and the stranding time for a single metal cable is significantly shortened, saving substantial labor costs. Simultaneously, mechanized tension and pitch control eliminates individual differences introduced by manual operation, significantly improving batch consistency and appearance quality, providing a reliable equipment foundation for the large-scale, standardized production of medical metal cables.

[0050] In some embodiments, the intermediate spindle transmission mechanism 3-3 includes an intermediate bearing housing 3-3-1, an intermediate spindle 3-3-3, an intermediate spindle gear 3-3-2, an intermediate spindle winding transmission gear 3-3-4, an intermediate core tube 3-3-5, an intermediate core tube fixing bracket 3-3-7, and an intermediate die sleeve 3-3-6; the intermediate spindle 3-3-3 is mounted on the intermediate bearing housing 3-3-1, and the intermediate spindle gear 3-3-2... 3-2 is installed on the middle layer main shaft 3-3-3.

The middle layer die sleeve 3-3-6 is installed on the middle layer central core tube 3-3-5.

[0051] In some embodiments, the intermediate winding mechanism 3 further includes multiple intermediate winding disc mechanisms 3-13 and multiple intermediate winding disc gears 3-17. Each intermediate winding disc mechanism 3-13 includes an intermediate winding disc wire carrier 3-13-1, a small intermediate winding disc turntable 3-13-2, an intermediate flange sleeve 3-13-3, a small intermediate disc gear 3-13-4, a small intermediate disc gear shaft 3-13-5, and a central intermediate wire feeder 3-13-6. The multiple intermediate winding disc wire carriers 3-13-1 are mounted on the small intermediate winding disc turntable 3-13-2, and the small intermediate disc gear 3-13-4 is mounted on the small intermediate disc gear shaft 3-17. On 3-5, the two ends of the middle layer small turntable gear shaft 3-13-5 are respectively fixed in the bearing holes of the two middle layer flange sleeves 3-13-3. The middle layer center wire feeder 3-13-6 is installed on the upper end of the middle layer small turntable gear shaft 3-13-5 and does not rotate with the middle layer winding disc small turntable 3-13-2, but maintains its orientation.

[0052] In some embodiments, the middle layer winding mechanism 3 further includes a middle layer support plate 3-14 and a plurality of middle layer connecting rods 3-15. The middle layer support plate 3-14 is fixed together with the middle layer upper turntable 3-12 through the plurality of middle layer connecting rods 3-15. The middle layer large turntable motor 3-4 drives the middle layer lower turntable 3-11 and the middle layer upper turntable 3-12 to perform circular motion, and the middle layer small turntable motor 3-8 drives the middle layer winding disc mechanism 3-13 to perform circular motion through the middle layer main shaft transmission mechanism 3-3.

Each layer of wire carriers releases wire under constant tension, and the metal wire forms a uniform and tight spiral winding structure on the surface of the core wire. This effectively eliminates the defects of uneven interstrand gaps and local looseness in traditional manual twisting. From the two dimensions of tension and twist control, it ensures that the mechanical strength and fatigue life of the metal cable meet the requirements of clinical implantation.

[0053] During operation, the small turntable motor 3-8 twists the threads on each of the middle layer winding disc mechanisms 3-13 and the threads on the middle layer center feeder 3-13-6 together. Then, each twisted strand is passed through the hole of the middle layer support disc 3-14 at the die opening.

The outer layer wire-carrying spool 4-12-1 and the middle layer wire-carrying spool 4-12-2 respectively perform circular motions in opposite directions.

[0057] During operation, the outer layer small stranding disc motor 4-6 twists the wires of the outer layer wire carrying disc 4-12-1, the middle layer wire carrying disc 4-12-2, and the center wire carrying disc 4-12-3 together, and then pulls them out separately and passes them through the corresponding holes of the outer layer total stranding disc 4-13 at the die opening. The outer layer total stranding disc 4-13 moves in a circular motion with the outer layer shaft seat upper disc 4-11, twisting the strands into one strand, forming a multi-layer spiral structure on the surface of the spiral structure pulled by the middle layer winding mechanism 3.

[0058] In some embodiments, the dual-drive traction machine 5 includes a reduction motor bracket 5-1, two sets of reduction motors 5-2, and two traction wheels 5-3. The two sets of reduction motors 5-2 are respectively installed above and below the reduction motor bracket 5-1, with the lower reduction motor 5-2 installed at an angle. The two traction wheels 5-3 are respectively installed on the upper and lower reduction motors 5-2, with the center of the first slot of the lower traction wheel 5-3 aligned with the center of the wire outlet of the upper traction wheel 5-3. This installation method allows the core wire to obtain stable traction force under the constraint of the groove of the groove wheel. When tractioning the product, the product will not rub against the edge of the groove of the traction wheel. The twisting pitch is precisely controlled by the traction speed and the rotation speed of the winding disc, effectively ensuring the interstrand density and surface flatness of the metal cable.

[0059] In some embodiments, the take-up and unwinding mechanism 6 includes a linear motion module bracket 6-1, a motion module 6-2, a take-up and unwinding reduction motor 6-3, a locking pin bracket 6-4, a locking pin 6-5, and a take-up and unwinding reel 6-6.

[0060] During operation, the core yarn is pulled out from the spool of the take-up and release mechanism 6 at one end, passes sequentially through the center of the inner winding mechanism 2, the middle winding mechanism 3, and the outer winding mechanism 4, and winds into the groove of the grooved wheel of the dual-drive traction machine 5. It is then pulled out from the grooved wheel and wound onto the spool of the take-up and release mechanism 6 at the other end. After the core yarn is fixed, the yarns on the multiple sets of yarn carriers on the inner winding mechanism 2 are pulled out and fixed onto the core yarn. The yarns on the multiple sets of winding spools on the middle winding mechanism 3 and the yarns on the central release device are pulled out, and the yarns on the multiple sets of outer, middle, and central yarn carriers on the outer winding mechanism 4 are pulled out and fixed respectively.

[0061] Simultaneously, the take-up and release mechanism 6, inner winding mechanism 2, middle winding mechanism 3, outer winding mechanism 4, and dual-drive traction machine 5 are activated. The inner winding mechanism 2 twists the inner wires of the medical metal cable together. The product twisted by the inner winding mechanism 2 is pulled to the middle winding mechanism 3 by the dual-drive traction machine 5. The middle winding mechanism 3 twists multiple strands of wire onto the product of the inner winding mechanism through the wire carrier on the winding spool mechanism. Then, the product is pulled to the outer winding mechanism 4 by the dual-drive traction machine 5 for compound twisting. Finally, the twisting pitch is controlled by the dual-drive traction machine 5, and the twisted product is wound onto the spool by the take-up and release mechanism 6.

[0062] The inner winding mechanism 2, the middle winding mechanism 3, and the outer winding mechanism 4 rotate in different directions, and the spiral direction formed by each layer is also different. The wire carrier on the central wire carrier plate of each layer maintains directional movement to ensure that the wire is not twisted during the release process. From the release of the core wire, the synchronous twisting of multiple layers of metal wires, the control of the twist pitch to the winding of the finished product, the entire process is completed automatically by the various mechanisms on the frame 1. This completely changes the traditional operation mode of relying on manual layer-by-layer twisting and braiding, greatly increasing the production cycle and significantly shortening the twisting time of a single metal cable, saving a lot of labor costs. At the same time, the mechanized tension and twist pitch control eliminates the individual differences introduced by manual operation, significantly improving the batch consistency and appearance quality of products, and providing a reliable equipment foundation for the large-scale and standardized production of medical metal cables.

[0063] Secondly, the present invention provides a method for preparing a high-performance medical metal cable, using the aforementioned high-performance medical metal cable fabrication platform, comprising: The core wire is fixed to the take-up and release mechanism 6 at one end, pulled out and passed through the central core tube of the inner winding mechanism 2, the central core tube of the middle winding mechanism 3, and the central core tube of the outer winding mechanism 4 in sequence, and wound into the groove of the grooved wheel of the dual-drive traction machine 5, and then pulled out from the grooved wheel and wound onto the take-up and release mechanism 6 at the other end. The yarns on the multiple sets of yarn carriers on the inner winding mechanism 2 are pulled out and fixed to the core yarn; the yarns on the multiple sets of winding disc mechanisms and the yarns on the central yarn feeder on the middle winding mechanism 3 are pulled out, and the small turntable motor is started to twist the yarns on each winding disc mechanism and the yarns on the central yarn feeder together. Then, each twisted strand is passed through the hole of the support disc at the die opening. The support disc moves in a circular motion with the upper turntable to further twist the strands synthesized by the winding disc mechanism into a spiral structure; the yarns on the multiple sets of outer layer yarn carriers, middle layer yarn carriers and central yarn carriers on the outer winding mechanism 4 are pulled out respectively, and the small plying disc motor is started to twist the yarns of each layer yarn carrier together. Then, they are pulled out respectively and passed through the corresponding holes of the plying disc at the die opening. The plying disc moves in a circular motion with the upper disc of the shaft seat to twist the strands into one strand. Simultaneously, the take-up and release mechanism 6, the inner winding mechanism 2, the middle winding mechanism 3, the outer winding mechanism 4, and the dual-drive traction machine 5 are activated. The twisting pitch is controlled by the dual-drive traction machine 5 to form a multi-layer spiral structure medical metal cable on the core wire, and the twisted medical metal cable is pulled onto the take-up and release mechanism 6.
