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.

Why is it better and safer to keep the fermentation bed dry during production? The reason lies in the powerful activity of the functional microbial strains used in the pig bed. These microbes function effectively under specific conditions, such as when using rice bran as a carrier with a moisture content of 65%. However, during operation, the bedding doesn’t need to be watered directly. Instead, when the functional microorganisms are active, maintaining a moisture level of 65% is ideal and safer to dry. But why is that the case?
Let’s take the example of the Jinbao fermentation bed to clarify this. In the Jinbao system, the sawdust layer is usually only 50 cm thick, and the moisture content is kept at 65%, which is a standard requirement. It uses only a specific type of bacterial culture, and no additional water is needed, making it more secure. But where does the moisture come from?
First, let's look at the sources of moisture:
1. **Sawdust itself**: Fresh sawdust, such as from Chinese fir, eucalyptus, or other types of wood, naturally contains a certain amount of moisture. The water content can vary depending on the type of tree, but it's generally around 60%. Dry sawdust, on the other hand, may have a moisture content as low as 30% of its dry weight.
2. **Pig excrement**: This is a major source of moisture. Pig feces typically contain about 60% water, and urine adds even more. For example, each pig produces about 4 kg of excrement per day. In a 20-square-meter fermentation bed housing 15–20 pigs, this results in about 60 kg of water daily—substantial enough to maintain the required moisture without adding any extra water.
3. **Other sources**: There may also be small amounts of moisture from drinking water residues, feed leftovers, or rainwater. However, these are minor and should be managed carefully through proper sheltering to prevent excessive moisture buildup.
Secondly, not adding water is actually better and safer for the fermentation process. Since the moisture comes naturally from the sawdust and pig waste, there’s no need for human intervention. If too much water is added, the moisture level could exceed 65%, leading to an environment that’s too wet for the beneficial microbes. This could cause them to die off, rendering the fermentation bed ineffective. On the other hand, if the moisture is too low, the microbes will just go into a dormant state, and their activity will slow down. But once the right moisture level is reached, they become active again, helping to break down waste, reduce odor, and improve overall efficiency.
In conclusion, keeping the fermentation bed dry and relying on natural moisture sources is not only safer but also more effective in maintaining a healthy and sustainable system.
