ABSTRACT
BACKGROUND: Training for acupuncture manipulation is an important step from theory to clinical practice in Mongolian medicine. OBJECTIVE: To establish mechanical models related to different Mongolian acupuncture techniques of the upper limb acupoints in a virtual environment, and to demonstrate the Mongolian acupuncture process of upper limb acupoints at multiple levels. METHODS: A professional from the Mongolian Medical College of Inner Mongolia Medical University performed a demonstration for Mongolian acupuncture of the forearm acupoints via perpendicular insertion (needle insertion at a 90° angle to the skin), oblique insertion (needle insertion at a 45° angle to the skin), and cruciform insertion (needle rotation after insertion into the skin). Information was collected with ATP-IV acupuncture manipulation parameter tester within 10 seconds of acupuncture. The scanning conditions were voltage 9 V and current 250 mA, and the remaining parameters were set to the default value. The voltage-time diagram was plotted based on X, Y and Z axis sampling information, and the acupuncture process model was established as previously reported. Biomechanical analysis was performed on the modeling of the Mongolian acupuncture process. The implementation of the research program was in line with the relevant ethical requirements of Inner Mongolia Medical University. RESULTS AND CONCLUSION: The parameters of perpendicular, transverse, and cross-shaped insertion were measured by the ATP-IV acupuncture manipulation parameter tester. The axial force of the needle raised rapidly after the needle tip touched the soft tissue surface, and dropped sharply, accompanied by the sense of frustration, after piercing the soft tissue. Then the resistance of the needle tended to be flat due to the soft tissue elasticity and friction. These findings were basically consistent with the biomechanical results reported by Okamura. Compared with the complicated acupuncture manipulation of traditional Chinese medicine, the acupuncture methods described in the Mongolian medical literature, characterized by simple operation and simple appliance, only include one three-step acupuncture technique combined with hand feeling and eight acupuncture techniques combined with acupoints.
ABSTRACT
Objective To investigate the feasibility to execute percutaneous kyphoplasty(PKP) in the field comprehensive surgical shelter during kinds of natural disasters. Methods Five experimental pigs underwent PKP in a comprehensive surgical shelter during simulated natural disasters, and were observed for operating time, intraoperative blood loss, complications and postoperative survival rate. Results All the 5 pigs had the operations completed successfully with high postoperative performances in extremities motion and survival rate, and the mean operating time was(43±5.7)min and the mean intraoperative blood loss was (42±3.6)ml.Cement penetrated into the intervertebral space of one pig with satisfactory extremities motion,while no complications occurred in the other pigs.Conclusion The comprehensive surgical shelter proves to enable PKP,and thus extends emergency treatment to the frontier during simulated natural disasters.
