Description

Technical Field

[0001] The present invention relates to the technical field related to bionic ligament medical devices, and in particular to a bionic ligament auxiliary device based on plasma and super freezing technology. Background Art

[0002] Synthetic bionic ligaments are mainly made of polyethylene fishing line and provide new solutions for a variety of medical and engineering applications. Especially in the field of medicine, the development of bionic ligaments has brought revolutionary progress to ligament repair and biomechanics research. Traditionally, cadaver models are the main way to conduct ligament experiments, but obtaining cadaver specimens is not only expensive, but also limited by supply chain, ethical issues and conditions of use. As an economical and convenient alternative, bionic ligament models provide laboratories and hospitals with efficient research and training tools. Although bionic ligaments have shown excellent application potential in many fields, a key issue is often overlooked: stress. In the field of materials such as metal steel, stress is regarded as a crucial physical quantity because it directly affects the strength, plasticity, fatigue life and safety of the material. However, in the field of bionic materials and biomechanics, the importance of material stress is often not given enough attention.

[0003] Bionic ligaments are subjected to complex mechanical environments during application, especially when the human body is moving. Every time the joint moves, stretches or bears weight, the ligament will be subjected to dynamic stress. This stress not only affects its immediate function, but also determines its durability and degradation rate in long-term use. If the bionic ligament cannot adapt to this complex stress distribution, it may cause its performance to deteriorate or fail prematurely in long-term use. Therefore, it is particularly important to conduct in-depth research on the stress tolerance of bionic ligaments in practical applications and design a device that can improve the mechanical properties of bionic ligaments according to different needs.

The inner ring of the heat preservation shell 1001 is fixedly installed with a second support frame 1003. The upper surface of the second support frame 1003 is fixedly installed with arc guide rails 1004 on both sides. The outer ring of the arc guide rail 1004 is fixedly installed with an arc rack 1005. A fixed platform 100 is arranged above the arc guide rail 1004. 6.

[0040] Furthermore, the hollow rollers 303 are respectively arranged on both sides of the fixed roller 307 and are in an equilateral triangle structure. There are two groups of fixed rollers 307 and they are symmetrically arranged on the diagonal of the outer shell 1. Through the arrangement of the fixed rollers 307 and the hollow rollers 303, the same distribution on the upper and lower sides of the outer shell 1 can be well coordinated for tension adjustment.

[0046] Furthermore, the liquid nitrogen tank 11 and the compressor 12 provide a cold source for the high-pressure freezing nozzle 1010. The connecting pipeline between the compressor 12 and the high-pressure freezing nozzle 1010 is guided by the wire board 1002.

[0047] Working principle: first, the bionic ligament is fed in from one end of the inlet 2, and then passes through the bottom of the hollow roller 303, passes through the top of the fixed roller 307, and then passes through the hollow roller 303 on the other side. At the same time, the position of the limit plate 305 is controlled by the bidirectional screw slide 304, so that the limit plate 305 limits and corrects the bionic ligament. Secondly, the bionic ligament will pass from the side of the pressure rod 5. When the bionic ligament passes through the fixed roller 307, the tension sensor 308 can sense it, and the position of the pressure rod 5 can be moved by the electric slide 4 to adjust the tension. Then, the bionic ligament passes through the middle position of the two sets of plasma generators 602, and then the plasma generator 602 is controlled by the pulse power supply 8 and the pulse controller 9 to perform high-energy discharge, and then the nozzle 604 on one side of the inverted crescent nozzle 603 is sprayed to efficiently treat the surface of the bionic ligament, and at the same time, the baffle 6 is driven by the cylinder 608. 07 slides to control the opening and closing of the nozzles 604 on both sides of the inverted crescent-shaped nozzle 603. When the surface of the bionic ligament is treated, it quickly enters the heat preservation shell 1001, and at the same time, the refrigerant is transported through the liquid nitrogen tank 11, and is transported to the high-pressure freezing nozzle 1010 through the compressor 12. Then, when it passes through the shunt pipe 1011, the shunt head 1017 at one end of the connecting shaft 1016 can be driven by the valve motor 1015 to rotate to control different openings. When the shunt head 1017 is above the spherical groove 1012, the direct nozzle 1013 is opened to spray the refrigerant. After the shunt head 1017 rotates ninety degrees, the direct nozzle 1013 can be closed and the scattering nozzle 1014 can be opened. When the shunt head 1017 is downward, it can be fully opened to quickly cool the surface of the bionic ligament. Finally, the processed bionic ligament can be transported out through the position of the fixed roller 307 and the hollow roller 303 below.
