Dalian - March 11, 2016 - Today, Professor Zhao Yu from West China Hospital of Sichuan University and Tang Wenlong, MD, from the Longmen District, Shenzhen, China, dressed in isolation gowns, are busy dissecting the Dalian Life Mystery Museum. The middle ear of the sperm whale tries to explore the hearing world of the sperm whale.
Â
Before and after Valentine's Day this year, two male sperm whales were killed in the beach along the coast of Jiangsu Rudong, causing widespread concern. After seeing Professor Zhu Hongjin, the director of Dalian Life Mystery Museum, after consulting with the local government, one of the sperm whales has now arrived at the Museum of Life Mystery. The curator hopes to make this sperm whale the world's largest whale through bioplastic technology. Plasticized specimens.
Â
The curator said: "Sperm whale belongs to the toothed whale. The toothed whale relies on hearing to perceive the world, so its hearing must be very sensitive. From the morphological point of view, study the morphology of the ossicles and the connections between them, and the anatomy of the inner ear. The characteristics will be very meaningful. The hearing of the sperm whale is mainly based on the bone conduction of the mandible, not directly by sound waves. Therefore, it is very meaningful to study and analyze the relationship between the bone conduction and the anatomy of the middle ear and inner ear."
Â
The curator also mentioned that there is almost no literature on the hearing of sperm whales, so the anatomical study of the sperm whale auditory system will be of great significance in the search for the hearing world of sperm whales.
Â
Dissecting the middle ear of a sperm whale is a very complicated process. Dr. Zhao Yu said: "Ocean creatures are definitely more dependent on bone conduction. The inner ear is more important to them, but we have very little understanding of the hearing system of sperm whales. Therefore, we hope that this anatomy can better explore the hearing world of sperm whales. The anatomical scene is stinking, and the middle ear of the sperm whale is dissected in such an environment. It is both a delicate workmanship and a very laborious 'dirty work'. Therefore, the power system required for dissection is It is crucial that Medtronic's advanced technology plays an important role in this anatomy."
Â
Dr. Tang Wenlong said: "Sperm whales are so sensitive to hearing, what is its ear, and what is the difference between the human ear and the human ear. Many questions are placed before us. We hope that this anatomy can completely contour the middle ear conduction system of the sperm whale. And the lost structure. However, this anatomy is extremely demanding for our fine operation, so the requirements for the surgical power system are also higher. The Medtronic IPC integrated power system just meets the needs of this anatomy."
Â
The IPC ENT integrated power system mentioned by the two ear specialists can help doctors provide efficient power and clear surgical field of vision while maintaining precise manipulation of the anatomical position. This anatomical sperm whale is preferred to require high-speed cutting efficiency to remove a large amount of bone, and then requires good stability, to ensure long-term fine operation, also requires a good handle design to ensure convenient operation, and IPC power The system is just right for these needs.
Â
Chen Shizhen, senior director of surgical technology business in Medtronic Greater China, said: "I am very pleased that two domestic authoritative ear specialists have chosen our IPC technology to help dissect the middle ear of sperm whale. As experts say, sperm whales rely on hearing to perceive the world, we I also hope that this study will help sperm whales create a better living environment and reduce the death of sperm whales.
Â
The production of sperm whale plasticized specimens by the Dalian Life Mystery Museum is of great scientific significance for understanding and studying sperm whales and cetaceans. In the process of anatomy of sperm whales, the museum will invite relevant experts at home and abroad to study and discuss. This anatomical study of the sperm whale auditory system is currently the first sperm whale research group.
