In medical surgery, especially in chest surgery, the sternum saw plays a vital role. The sternum saw is a surgical tool specially designed to cut the sternum, allowing the surgeon to access the chest cavity for further operations.
Function and design of sternum saw
The main function of the sternum saw is to cut the sternum so that the surgeon can access the heart, lungs and other organs in the chest cavity. Traditionally, there are two main forms of sternum saws: manual saws and electric saws.
1. Manual sternum saw: This saw is similar to an ordinary manual saw, but its design is specially optimized to be more precise and effective when cutting the sternum. Manual sternum saws are usually used for minor surgeries or when electric equipment is not available.
2. Electric sternum saw: The more commonly used in modern medicine is the electric sternum saw. This saw drives the saw blade through an electric motor, providing higher cutting efficiency and less physical exertion. Electric sternum saws are equipped with different saw blade types to suit different surgical needs and the hardness of the sternum.
Sternum saws are mainly used in chest surgeries, including:
1. Heart surgery: When performing heart surgery (such as coronary artery bypass grafting or heart valve surgery), surgeons need to access the heart by cutting through the sternum. Sternum saws play a key role in this type of surgery.
2. Lung surgery: For some surgeries that require the removal or repair of lung tissue, sternum saws are equally important. It allows surgeons to clearly see and operate on the lungs.
3. Chest trauma: When dealing with chest trauma (such as serious car accident injuries), sternum saws can help quickly open the chest for emergency treatment.
With the advancement of medical technology, the design and function of sternum saws are also constantly evolving. For example, modern electric sternum saws are lighter, have higher cutting accuracy and better safety performance. The application of new materials and technologies makes these tools more durable and reduces risks during surgery.
