The xiphoid process is at the lower end of the sternum and is made of cartilage in most people.
For cartilage, you don't need an electric saw, you can use surgical scissors. When doing anything, you can choose to break through from the easiest place and finally bite the hard bone. This is a common strategy, and the same is true in the medical path. Saw the xiphoid process before the sternum.
Cutting off is equivalent to opening a breakthrough. As with the previous point, the most important thing is to clean up the "things" attached to the bones.
The first assistant who is accompanying the surgeon does not use separation pliers this time, but uses pliers to clamp the small baffle on the xiphoid process, and then cleans up the "pile of debris" behind the "baffle". It's like you want to dismantle a piece of machinery.
It is impossible to do this without cutting the surrounding wires connected to the robotic arm.
The electric scalpel held by the surgeon squeaks and coagulates to incise the exposed rectus abdominis muscle after the xiphoid process is lifted. This location is close to the abdominal cavity, so be very careful to prevent excessive dissection and the fluid placed in the thoracic and pericardial cavity flowing into the abdominal cavity, which may cause
Complications of abdominal organs.
After the incision, a gap was exposed behind the xiphoid process. The surgeon put down the electric knife and stretched out a finger of his right hand to penetrate deeply from the gap to the left back of the sternum. This position is next to the pericardium. The doctor's finger gently and slowly pushed.
The pleura on the left and right sides of the mediastinum is pushed open and blunt dissection is performed.
If the child is younger, the doctor's fingers may be able to separate directly to the upper end of the back of the sternum. If the child is older, one finger cannot reach the upper end of the sternum. Like other engineering projects, in this case, the only way to use tools is to replace the fingers.
, put it in and insert it forward along the direction of your fingers. Doctors usually use long flat forceps close to the sternum to perform blunt dissection.
Use tools instead. Just like poking with fingers, you need to confirm where you have poked and whether you have penetrated. For this reason, after the long flat tweezers are inserted like this, the ends need to be connected to confirm that the target position of separation is correct.
To use an analogy, human tissue is like a large cave with many caves hidden in a mountain. It is complexly intertwined. Long flat tweezers are like a pole entering an entrance of a large cave. You have to ensure that the rope appears at the designated entrance. It needs to be at the designated entrance.
Connect the end of the pole.
This is reflected on the operating table. The surgeon needs to free his other hand to reach the incision at the upper end of the sternum. Since his right hand is occupied, he can only stretch out the fingers of his left hand and insert them from the upper end in an attempt to connect with the length of the upper part of the tissue that is separated from below.
Flat tweezers.
This separation path is located next to the back end of the sternum. The doctor's naked eye is blocked by the bone, so it is called the mysterious cave. Sometimes it may take a long time, and the fingers of the left hand and the end of the long flat forceps are not in contact.
I don't know if the separation is in place. If this happens, the doctor can only withdraw the long flat forceps outside, measure the length just inserted and compare it with the length of the sternum, so as to determine whether the depth just inserted is in place.
You may find it strange that the distance between the upper and lower ports of the sternum is not long and cannot be seen behind the bones. However, if the distance is not long, you can completely rely on feeling to catch it. How come the two ends are always unable to connect? I used to talk about general surgery in the morning
It's too blunt separation. Blunt separation is not hard cutting with an electric knife. To use another analogy, the doctor's fingers and tools are like tadpoles wandering around in a cave looking for their mother. It is impossible for them to forcefully split the wall between the caves.
, you have to go to the right path to encounter it.
It would be best to touch it so that the tadpoles can find their mother.
