Chapter 1514 Specialized Chapter, Anatomical Records
The pectoralis major and pectoralis minor muscles were developed normally, with neatly arranged muscle fibers, no signs of bleeding or contusion, and no signs of rupture. The intercostal muscles showed no bleeding or rupture, the ribs showed no fractures or dislocations, and the costal cartilage showed no damage. This indicates that the deceased's chest was not subjected to any external impact or injury, ruling out the possibility of death caused by chest trauma.
"Xiao Lin, record: subcutaneous fat thickness 1.5 cm, pale yellow, evenly distributed, no abnormalities; pectoralis major and pectoralis minor muscles are normally developed, muscle fibers are neatly arranged, no bleeding or contusion; intercostal muscles have no bleeding or rupture, ribs have no fractures or dislocations, costal cartilage is undamaged; pleura is intact, without rupture or bleeding, pleural surface is smooth, no adhesions, initially ruling out the possibility of death due to damage to thoracic organs or chest trauma." Zhang Lin reported slowly while performing the autopsy, his tone calm and professional.
"Understood, Teacher Zhang, all recorded!" Xiao Lin quickly took notes, his admiration for Zhang Lin's professionalism and rigor growing stronger—he wouldn't overlook any minute detail, and every discovery would be meticulously recorded to ensure the accuracy and completeness of the autopsy results.
Zhang Lin continued his work, the scalpel moving slowly, cutting open the pleura little by little. After the pleura was cut open, he carefully used sterile forceps and rib shears to cut the costal cartilages on both sides of the sternum, moving gently to avoid rib fragments falling off and damaging the internal organs in the thoracic cavity. After cutting the costal cartilages, he carefully used sterile forceps to peel back the sternal flap, opening the thoracic cavity and exposing the internal organs inside.
There was no blood or fluid accumulation in the pleural cavity, the pleural cavity was dry, and the internal organs such as the heart, lungs, trachea, bronchi, thymus, and mediastinum were in normal positions, intact in shape, without any abnormal lesions, injuries, or traces of bleeding.
"Xiaolin, record: No blood or fluid accumulation in the pleural cavity, and the pleural cavity is dry; Heart: Located in the middle left of the pleural cavity, normal in shape, approximately 12 cm x 9 cm x 6 cm in size, dark red in color, smooth in surface, without rupture, bleeding, or lesions, consistent with the characteristics of a normal heart."
"Lungs: Both lungs are normal in shape and symmetrical in size, with no abnormal lesions."
Using sterile tweezers, Zhang Lin carefully combed through every internal organ in the chest cavity, checking them one by one to ensure no detail was missed. His movements were gentle yet precise, his gaze focused and sharp, as if he were examining a precious work of art, allowing no flaws whatsoever.
"The internal organs of the chest cavity showed no damage or abnormal lesions, ruling out the possibility of death caused by damage to the internal organs of the chest cavity or hidden diseases. This is consistent with the results of the abdominal autopsy. Further confirmation indicates that the deceased's only fatal injury was a stab wound to the left side of the abdomen from a single-edged sharp instrument, which led to spleen rupture and acute hemorrhagic shock." After completing the examination, Zhang Lin said firmly, his judgment becoming even clearer.
"Understood, Teacher Zhang. Recording complete. The thoracic autopsy revealed no abnormalities, further confirming the accuracy of the cause of death!" Xiao Lin quickly wrote down the record, a relieved expression on his face—although the case was still difficult, at least they had clarified the cause of death, which was an important breakthrough.
“Okay, next, extract one heart tissue sample and one lung tissue sample,” Zhang Lin continued. “Using a sterile scalpel, take a piece of the left ventricular wall tissue from the heart, put it in a sterile tissue specimen bottle, label it with relevant information, and send it to the laboratory for pathological examination to confirm whether there are any potential pathological changes in the heart and lungs, completely rule out the possibility of death caused by latent diseases, and ensure the rigor and accuracy of the autopsy results.”
"Understood, Teacher Zhang!" Xiao Lin quickly replied, picking up a sterile scalpel and two sterile tissue specimen bottles and handing them to Zhang Lin. Zhang Lin took the instruments, gently extracted the samples, carefully cutting off a small piece of tissue from the left ventricular wall of the heart and the upper lobe of the right lung, placing them into the corresponding tissue specimen bottles, pouring in an appropriate amount of fixative, sealing them, and then handing them to Xiao Lin.
Xiaolin took the samples and quickly marked them: "Unidentified male corpse, heart tissue sample, extraction time: 12:15 pm today" and "Unidentified male corpse, lung tissue sample, extraction time: 12:15 pm today". Then, she neatly placed the samples on the sample tray, together with the previously extracted samples.
"Teacher Zhang, the heart and lung tissue samples have been extracted and labeled!"
Zhang Lin nodded, his gaze sweeping over the internal organs in the chest cavity once more. After carefully examining the area and confirming that no details had been missed and no other abnormalities were found, he said, "Alright, the chest cavity dissection is complete. Xiao Lin, carefully cover the internal organs in the chest cavity with sterile gauze to prevent contamination. Then, record the time when the chest cavity dissection ended."
"Understood, Teacher Zhang!" Xiao Lin quickly replied, picked up sterile gauze, and carefully covered the internal organs inside the deceased's chest cavity. Then, glancing at the clock on the wall, he quickly recorded: "Record: Thoracic autopsy completed, time: 12:20 PM; Key findings of the thoracic autopsy: no blood or fluid accumulation in the thoracic cavity; all internal organs in the thoracic cavity, including the heart and lungs, are normal in shape, without damage or abnormal lesions, ruling out the possibility of death caused by damage to internal organs or latent diseases; two tissue samples were extracted from the heart and lungs, which have been marked and stored without omission or error."
Zhang Lin nodded slightly after watching Xiao Lin finish taking notes. Then, he adjusted the angle of the operating light, shifting the light to the deceased's neck area, and said in a serious tone, "The thoracic autopsy is finished. Next, we will proceed with the neck autopsy. The focus of the neck autopsy is to examine the neck tissues, trachea, esophagus, neck blood vessels, nerves, and other structures to rule out the possibility of death due to mechanical asphyxiation (strangulation, strangulation). At the same time, we will check the neck for any hidden external injuries, injection marks, or other traces to look for clues that can identify the deceased or the suspect—the murderer has a very strong counter-investigation awareness, and we cannot overlook any small clue, even a tiny needle mark on the neck could be crucial."
"Understood, Teacher Zhang, I will be extra careful, making sure to record and observe everything thoroughly, and I won't overlook any detail!" Xiao Lin quickly agreed, his pen ready to be used again, his eyes becoming even more focused. "Record: Thoracic dissection completed, time: 12:20 PM today; Next, proceed with the neck dissection, focusing on examining the neck tissues, blood vessels, nerves, trachea, esophagus, etc., to rule out the possibility of death due to mechanical asphyxiation or injection of poison, and to look for suspicious trace evidence and individual identification characteristics."
Zhang Lin took a deep breath, picked up the sterile scalpel again, and said to Xiao Lin, "Neck dissection, incision direction: from the midpoint of the lower edge of the mandible, along the midline of the neck, down to the suprasternal notch, connecting with the thoracic anatomical incision to form a complete longitudinal incision; incision angle: 20° to the skin, with the blade facing the inside of the neck; incision force: gentle and moderate, avoiding damage to the neck blood vessels, nerves, and trachea, and preventing blood from contaminating the neck tissue and affecting the accuracy of the test results—the neck has a dense network of blood vessels and nerves, and any accidental damage may destroy trace evidence and affect our judgment."
