First of all, you need to understand the human anatomy structure, the thymus of the mediastinum of the heart, and almost partly hidden behind the sternum. It is equivalent to saying that it is basically impossible to bypass the sternum, a large stone blocking the road, for surgery. It is better to split the sternum than to break many other bones when taking off the road. The front chest of the human body does not have any other bones except the sternum. Moreover, this approach is the fastest. Split the sternum to quickly expose important organs such as the mediastinum of the heart. Since you choose thoracic surgery, the first thing is to ensure that the surgery field is spacious, bright and thorough, so that the doctor can work quickly to solve the surgery early. This method is to choose a central abdomen incision like abdominal surgery. Both the thoracic cavity and the abdominal cavity can be imagined as sacks. If you split it in the middle, it is easiest to see clearly what is in it.

When it comes to chopping bones, you will naturally think of the orthopedic knife mentioned before. For a sternum like a big bone like a big tree trunk, the doctor will directly use a chainsaw faster. The chainsaw that the doctor takes is definitely not a chainsaw used on the construction site outside. If you take that one on the stage, you will probably have to scare people to death.

Orthopedic knife can be made very light, like a chainsaw used for surgery, and it looks like a flash drill. As long as the power is sharp enough, it will work the same. The size of the tool depends on the size of the target object. Just splitting a bone is not a big tree, so why do you have to use a tool?

Chainsaw cuts a big tree, not randomly. You have to cut it in a neat way and split it in two instants to achieve the goal of easily cleaning up the mess afterwards.

The surgical chainsaw is called a sternum saw. When splitting the sternum, it should also have planning and purpose. The incision is made on the center tangent, and the incision is neat, and the incision is beautiful. The second is that the incision bones must be re-tied after the operation. It is easy to benchmark and the incision heal easily. The third is that the surgical field after the sternum is exposed, which is conducive to subsequent visceral surgery. If the incision is crooked, you must not readjust the surgical field after opening the incision, and the patient is in pain.

The important node is here, so you need to cut the center line accurately.

I don’t know if you can see where the midline is when you touch the skin and position the sternum before the operation. After you have a surgery, you have incited the skin. The previously predicted line will definitely be gone, and you need to re-determine the midline position.

After the surgery, the doctor needs to clarify the midline of the sternum all the way. The process of exploring this process is also preparing for splitting the sternum. It is not easy to say that this process is simple. A human bone is not a simple bone, but other things such as skeletal muscles are attached to the upper part. When repairing bones, the doctor must use his hands to use tools like brushing away dust and wires from the metal components of the machine, and first sort out and peel off these attachment components before starting. As a very important large bone in the human body, there are many muscle groups attached to it.

The main surgeon, wearing gloves, reached in and touched it, took out the ribs on both sides to determine the outer edge of the sternum, and then set two or three midpoints as the line connecting the upper and lower midpoints. After that, the nurse handed over a midpoint, which is what we usually call the mid-point hemostasis forceps.
