The xiphoid process is at the lower end of the sternum, and most people are cartilage.

For cartilage, you can use chainsaws, and surgical scissors. You can choose to break through from the easiest place to start and then chew hard bones. This is the same in the medical path. Scimitar cutting off the xiphoid process is equivalent to opening a breakthrough. As before, the most important thing is to clean up the "things" attached to the bones.

You should accompany the main knife to Ichisuke this time, and use the clamp to clamp the small baffle, the xiphoid process, and then clean the "pile of debris" behind the "bag". It is impossible to remove a robotic arm without cutting the wires connected to the robotic arm around it.

The electric knife held by the main surgeon electrocondenses the exposed rectus abdominal muscle after the xiphoid process is lifted. Here you are close to the abdominal cavity, be very careful to prevent excessive dissection of the fluid placed in the chest pericardial flowing into the abdominal cavity and causing complications of the abdominal organs.

After incision, a gap was exposed behind the xiphoid process. The main knife put down the electric knife, stretched out a finger of the right hand and went deep into the left posterior side of the sternum. This position was next to the pericardium, and the doctor's fingers gently pushed it slowly and pushed the pleura on the left and right sides of the mediastinum, which was done blunt separation.

If this child is younger, the doctor's finger may be able to be separated directly to the upper end of the back of the sternum. If it is bigger, one finger cannot reach the upper end of the sternum. Like other engineering, in this case, the only way is to use tools to replace the fingers, put them in and insert them forward in the direction of the finger. Doctors usually use long flat tweezers to close the sternum for blunt separation.

Replace with tools, just like finger poking, you need to determine where the poking was made. For this reason, after inserting Changping tweezers like this, the end needs to be connected to confirm that the target position of the separation is correct.

To put it in a metaphor, human body tissue is like a large cave with many caves hidden in a mountain, with complex interweaving. Long flat tweezers are like a pole entering an entrance to a cave. If you want to ensure that the rope appears at the designated hole, you need to connect the end of the pole at the designated hole.

Embodied on the operating table, the main surgery needs to free up the other hand to the incision at the upper end of the sternum. Since the right hand is occupied, the only thing that can extend the finger of the left hand and insert it from the upper end to try to connect the long flat tweezers that separate the tissue upwards below.

This separation path is a separation next to the back end of the sternum. The doctor's naked eyes are blocked by the bones and is invisible, so it is called the Mysterious Cave. Sometimes it may be inserted for a long time, and the fingers of the left hand and the end of the Changping Tweezer are not in contact, so it is unknown whether the separation is in place. If this happens, the doctor can only withdraw the Changping Tweezer outside and compare the length of the sternum just inserted to determine whether the depth of the insertion just now is in place.

You may find it strange. The distance between the upper and lower ports of the sternum is not long, and it is said that it is invisible to be seen behind the bone, but it is not long to catch it. If you want to catch it, you can feel it. How can you never contact both ends? In the past, general surgery has talked about blunt separation early in the morning. Blunt separation is not a hard cut by the electric knife. For example, a doctor's fingers and tools are like tadpoles wandering in a cave to look for their mothers. It is impossible to say that you can hardly split the walls between the caves. You must go to the right path before you can touch it.
