The invention discloses a preparation method of a non-stick pan with a wear-resistant ceramic coating, which comprises the following steps: step S1: performing sandblasting and roughening treatment on the metal pan body to form an uneven convex structure on the inner surface of the pan, and then performing Degreasing treatment and cleaning for later use; step S2: by weight, respectively weigh 45-65 parts of boron-modified silica sol and 30-50 parts of silane-modified nano-titanium sol; and add 10-15 parts of additives and 1.5 ~4.5 parts of suspending agent, stir and mix evenly to obtain coating slurry; step S3: coat the coating slurry obtained in step S2 on the inner surface of the pot in step S1, first use UV curing, and then quickly dry to obtain The wear-resistant ceramic coating is non-stick. The non-stick pan ceramic coating prepared by the invention not only has the characteristics of high-temperature boiling resistance and anti-sticking, but also has the advantages of anti-cracking, antibacterial and wear-resistant, and meets the long-term safe use requirements of the non-stick pan coating.

The invention relates to an absorbable screw and a soft tissue fixing device containing the same and belongs to the technical field of medical instruments. The absorbable screw comprises, by weight, 10-20% of poly(butylene-co-epsilon-caprolactone carbonate), 70-90% of poly(lactic-co-glycolic acid) copolymer and 1-5% of N-hydroxysulfosuccinimide sodium salt, wherein the poly(lactic-co-glycolic acid) copolymer is synthesized by PDLA [poly(d-lactic acid)] and PGA (polyglycolic acid), and a molar ratio of the PDLA to the PGA is 40-60 to 60-40. The absorbable screw is good in degradation stability, little irritating to tissues, good in compatibility and beneficial to hernia healing. The soft tissue fixing device containing the absorbable screw comprises a detachable catheter which is coated with a compatible lubricating coating, thereby being applicable to laparoscopic hernia repair operations. The soft tissue fixing device containing the absorbable screw has the advantages of adhesion prevention and convenience and reliability in operation; the catheter is a detachable replacement part, and accordingly a doctor can reuse the soft tissue fixing device only by replacing the catheter.

The invention discloses a preparation method of an antibacterial and wear-resistant composite non-stick pan coating, which comprises the following steps: S1: performing sandblasting and roughening treatment on the metal pan body, and then degreasing and cleaning for standby; S2: applying nano-zinc powder , Nano-alumina powder and dispersing aid are evenly ball-milled, then evenly mixed with silane coupling agent and deionized water, then sequentially add zinc metal organic framework and silane coupling agent, continue to stir, and evenly coat on the inner surface of the metal pot , after high-temperature calcination, the non-stick pan bottom layer is obtained; S3: Weigh a certain amount of silane-modified nano-silica sol; then add additives and suspending agents, stir and mix evenly, and then apply it on the bottom layer, and then perform UV curing and drying successively. Get a composite ceramic nonstick coating. The non-stick pan ceramic coating prepared by the invention solves the problems of poor antibacterial performance, easy cracking, poor wear resistance and short service life of the existing non-stick pan coating, and meets the long-term safe and healthy use requirements of the non-stick pan coating .

Belonging to the paint field, the invention in particular relates to a preparation method of a sprayable transparent super-amphiphobic paint. The method includes the steps of: A. calcining 0.1-10g ofa silicon source under a 400-1200DEG C temperature condition for 2-6h to obtain a silica aggregate; B. modifying the silica aggregate obtained in step A by vapor deposition or liquid-phase condensation, and then performing drying to obtain a silica aggregate; and C. adding a solvent into the silica aggregate obtained by drying after modification in step B so as to obtain a suspension solution witha mass concentration of 1-100mg / mL, i.e. the product. The preparation method provided by the invention is simple, and the obtained super-amphiphobic paint has super-hydrophobicity, super-oleophobicity, oil stain resistance, adhesion prevention, and corrosion protection properties, and at the same time has high transparency, friction resistance, green and environmental protection and other excellent properties.

The invention relates to a soft tissue fixing device with absorbable screws and belongs to the technical field of medical apparatus and instruments. The soft tissue fixing device with the absorbable screws comprises a driving device, a screw pipe and a driving rod, wherein the screw pipe is externally in screw joint with a guide pipe; the guide pipe is internally provided with multiple absorbable screws; thread structures are formed on nailed beams of the absorbable screws and provided with screw lead springs; the multiple absorbable screws are sequentially and serially connected end to end so as to be arranged in the guide pipe with a spiral groove. When in use, a trigger is pulled, so that the driving rod is driven by the driving device to rotate, and furthermore the absorbable screws can be emitted out from the guide pipe one by one during herniorrhaphy under a laparoscope. The soft tissue fixing device with the absorbable screws is especially applicable to the herniorrhaphy under the laparoscope, and has the characteristics of adhesion prevention, and convenience and reliability in operation; the guide pipe is a detachable replacement part, so that the fixing device can be repeatedly used only by replacing the guide pipe.
