First, a new type of fruit and vegetable preservative: A new type of preservative has been developed at the Hokkaido Agricultural Products Processing Center in Japan. Its production and use methods are: take potassium sulfite or sodium sulfite 79% - 80%, starch 10% - 11%, calcium stearate 10% (above are all weight percentages), mixed into fine, press 1 g 1 Packed in a small paper bag. When in use, they should be placed in a container for storing fruits or vegetables or covered in a plastic film, so that they can be volatilized naturally. Usage: Apples, pears, oranges 2-3 grams per kilogram, grape 5 grams per kilogram, fruits and vegetables can be stored for 2-3 months, the loss is only 2% -3%, without the loss of the control group of the agent Up to 60% - 70%. The use of this preservative has obvious economic benefits. II. Acetate Storage Feed Cereals: California Grain Storage and Transportation Corporation has developed a new method to spray a layer of 15% acetic acid on top of each layer of grain feed when loading feed, grain or crushed cereal feed into a warehouse. 5% of propiolic acid. Because both acetic acid and propiolic acid can inhibit seed germination and prevent microbial survival and reproduction. The results showed that after one year of preservation of grain and feed by this method, the nutrient content of grain and feed did not decrease, and the control group of this method was not used, and its nutrient content was reduced by 18%-20%. Third, the new method of egg preservation: Japan Fukushima Livestock Research Institute developed a new method. First, the selected egg is placed in a gas-tight plastic bag. Then, the bag is filled with nitrogen to discharge air, and then stored in an environment of about 10°C. The hatching rate of eggs preserved by this method is significantly higher than that of eggs preserved by ordinary methods. The hatching rate after 1 week of preservation is increased from 65% to 75%, and that from 2 weeks is increased from 60% to 70%. It is preserved for 3 weeks. The hatching rate reached 68% and 60% in 4 weeks. However, the hatching rate of ordinary methods for more than 2 weeks is less than 40%.

Laparoscopic instruments are medical devices used in minimally invasive procedures. These instruments are designed to be inserted through small incisions in the body, allowing surgeons to operate with less pain, scarring, and recovery time than traditional open surgery.
Advantages of Laparoscopic Instruments:
1. Smaller incisions: Laparoscopic instruments allow the use of smaller incisions, reducing scarring, pain and recovery time.
2. Improved visualization: Laparoscopic instruments provide a better view of the surgical site, allowing for more precise and accurate surgical procedures.
3. Reduced risk of infection: Compared with traditional open surgery, laparoscopic surgery usually has a lower risk of infection.
4. Reduced blood loss: Laparoscopic instruments are designed to minimize tissue trauma, thereby reducing blood loss during surgery.
5. Faster recovery: Compared with traditional open surgery, laparoscopic surgery usually has a faster recovery time, allowing patients to return to normal activities sooner.
