Disposable Endo Fascia Closure System
Disposable minimally invasive fascial closure device is a medical device used to close the abdominal fascia layer after laparoscopic surgery. The device consists of a needle and suture that can be inserted through a small incision in the skin and used to close the layers of fascia without the need for a larger incision. The device is designed to reduce the risk of complications associated with traditional methods of fascial closure, such as wound infection, hernia and dehiscence. The single-use nature of the device also reduces the risk of cross-contamination and infection. Use of the device could shorten recovery time and improve outcomes for patients undergoing laparoscopic surgery.

Overnight winter cabbage is a good variety of easy-to-control, high-yield, but nursery time is at the highest temperature in the north. High temperature, rain, and drought cause certain difficulties for nursery, resulting in annual reduction in planting area by more than 30% due to low emergence rate, causing farmers With great economic losses, how can we scientifically cultivate young seedlings of cabbage to achieve Miao Qi Miao? First, the first good nursery plots, 40-60 square meters seedbed. In particular, the spherical winter cold cabbage has high seed prices. Only thin seeding can maintain large seedlings and strong seedlings, which reduces the cost of seed production. Thin-seeding seedlings can also extend the time of cabbage in the seedbed to prevent fall crops from falling in time and affect planting. The nursery plots must be selected from fertile sandy loam, which is not easily flooded, and after harvesting the spring crops, the sorghum should be ploughed in time. On July 20th, the cabbage was sown, and the seedlings in the sunbeams were sown. With the arable land per 667 square meters (one acre) application of high-quality compound fertilizer 40 kg. The selection of compound fertilizer must pay attention to the selection of brand products with relatively stable quality. Some unstable compound fertilizers are unstable in content. Volatile ammonia ignites the seedlings. It is strictly forbidden to use unfermented chicken manure and urea, ammonium bicarbonate and other nitrogen fertilizers, and to fully use the fertilizer. After mixing, the seedlings are finely chopped with fine pestle and sowed for sowing. Second, fine seeds broadcast, rain, pest control, anti-high temperature. Before sowing, cabbage seeds were mixed with soil and boring for 6 hours. Before sowing, the water temperature seedbed was soaked and then aired slightly. The seeds were sown after five in the afternoon and sowed with more fine soil to ensure that the soil-doped seeds could be covered with a thin layer of seedlings on the seedbed. The soil must be thin, which can significantly increase the rate of emergence. Such as when the seeds are even when the rainy weather, you can not cover the soil, after the rain and then sprinkle a layer of fine soil, control of underground pests, soil mix can be mixed with phosphorus, organic phosphorus pesticides can also be used to seduce wheat bran to kill underground pests. After sowing, a small shed can be used to cover 60% of the shade net to prevent rain and sun. Shadeless nets also use small arches to cover straw protection. At the time of sowing, in order to reduce the production cost, it is recommended that the farmer's friends use seedlings made of nutrients or nutritional patches, which can save 30 to 50% of the medium amount and significantly increase the emergence rate. Third, strengthen seedling management and timely prevention and control of pests and diseases. After sowing cabbage, generally 3 to 4 days to Qimiao, Qimiao must pay attention to exposing the grass in the evening to curb seedlings, so as not to form high leg seedlings. Droughts should be sprayed in time, and water spray can be used every afternoon to effectively reduce ground temperature, and also to promote seedlings to grow into early seedlings to increase their resistance to stress. The disease of seedlings is mainly blight and damping-off. No. 1 or No. 2 spray or 72% of Pric 600 times with 2 sprays, insect pests are mainly cabbage caterpillars and beet armyworm, can be used to inhibit Taibao, Ruijin special prevention. Four, and Ming Teng, planting is the key. The general management level, the early and late winter cabbage planting is the key to successful planting. The time for colonization in the southern part of Shandong Province is limited to the September 20th of the Gregorian calendar. If it is postponed to October 1, the phenomenon of premature bolting is extremely serious under improper management measures. In the north of Shandong Province, the boundary between August 20 and September 10 should be adopted, and as early as possible, the autumn crops should be harvested in advance and planted in advance. After harvesting the previous crop, cultivated land in time. Combined with site preparation, Mushi high-quality organic fertilizer 3000-5000 kg, imported compound fertilizer 75 kg. Planting can be planted on a flat plant, with a width of 20-30 cm and a plant spacing of 30-33 cm. It can also be ridged and planted, ridge width is 70 cm, height is 10-15 cm, ridge roof is planted in double rows, plant spacing is 33 cm, and ridge distance is 30. cm. When planting, 10 kg of compound fertilizer can be used as seedlings in the mu, and the seedling water can be poured in time after planting. Five, water and fertilizer attack, manage to win high yield. After planting and easing seedlings, they generally coincide with autumn drought, and they must be watered in time. In mid-October, when the temperature turns cold, cabbage should enter the heart-wrapping period and should be followed by 20 kg of urea and watered once every 5-7 days to promote heart-wrapping as soon as possible. In mid-November, cabbage must have a 5-7 percent heartbeat, otherwise it will fail to grow. Then pour frozen water. During the winter season, if the drought is severe, it should be watered in time to prevent freezing. On the 15th of January, the Great Cold had passed, and the beginning of spring was approaching. The temperature rose and the cabbage began to grow. At this time, small water should be poured and top dressing should be carried out to prompt all the cabbages to be harvested, at the latest no later than March 25. After March 25, most cabbages began to break the ball and bolting. Sixth, winter cabbage cultivation should pay attention to the problem. 1. Cabbage fully ripened before winter, should be harvested as soon as possible, the degree of bagging more than 80%, the ability to reduce cold, harvest at this time, can reduce economic losses. After the colder areas in the north can be harvested, the soil concentration value can be stored in the small arch shed for 30-40 days. 2. If the timing of planting is postponed due to unexpected circumstances or early winter comes, the management of water and fertilizer in late autumn and early spring can be strengthened. In particular, the management of water and fertilizer in the early 70 days prior to bolting can be used to achieve good harvest. 3, north of Longhai Line, latitude in the 38 degrees -39 degrees area, it is recommended in a particularly cold year, covered with a simple small arch or covered wheat straw, both antifreeze and increase production, but also increased the freshness of winter cabbage when listed. According to the survey, the simple small shed is priced at 0.30-0.80 yuan more than the 500-gram market price without capping, and the 3,000 yuan per mu increase. 4. The breeding time in northern and central Hebei Province can be advanced to July 10-20, and the colonization time will be August 20 before. Appropriate regions: Henan, Shandong, Shanxi, Shaanxi, and central and southern Gansu.
