Orthopedic navigation device and preparation method thereof

Abstract

The invention relates to a navigation device in an orthopedics department and a preparation method of the navigation device. A first supporting rod and a second supporting rod of the navigation device in the orthopedics department are made of titanium alloy which comprises, by weight, 2 percent to 7 percent of Al, 0.5 percent to 3 percent of Sn, 0.5 percent to 3 percent of Zr, 2 percent to 4 percent of Mo, 2 percent to 4 percent of V, 1 percent to 2 percent of Mn, 1 percent to 2 percent of Cr, 0.1 percent to 0.5 percent of Si, the balance Ti and inevitable impurities. The preparation method of the navigation device in the orthopedics department comprises the steps of firstly, evenly mixing the raw materials, pressing the raw materials to obtain a Ti electrode, conducting vacuum melting on the Ti electrode in a vacuum consumable electrode electric-arc furnace, melting titanium alloy cast ingots obtained after being melted in the vacuum consumable electrode electric-arc furnace, then conducting pouring to obtain blanks, conducting postprocessing on the blanks to obtain the first supporting rod and the second supporting rod, and assembling the first supporting rod and the second supporting rod with other components to form the navigation device in the orthopedics department. The obtained navigation device in the orthopedics department is compact and perfect in whole structure, good in rigidity and light in total mass, and the strength of the supporting rods is high.

Description

technical field [0001] The invention relates to a medical device and a preparation method thereof, in particular to an orthopedic navigation device and a preparation method thereof, belonging to the technical field of medical devices. Background technique [0002] With the continuous increase of national support and the acceleration of the global integration process, China's medical device industry has developed by leaps and bounds. Among them, some medical devices similar to the orthopedic navigation system emerged at the historic moment. This system can greatly reduce the risk of complex orthopedic surgery and bring a new operation mode to orthopedic surgery technology-visualized surgical technology. This kind of orthopedic surgery uses the navigation system to formulate the surgical plan and intraoperative navigation before the operation. It can track the surgical instruments during the operation, and update and display the position of the surgical instruments on the pati...

Problems solved by technology

However, the overall structure of the device is fragmented, backward, and imperfect, and it is not closely connected with modern orthopedic surgery, which makes the device subject to many restrictions during use.

In addition, the materials currently used in medical devices are all made of stainless steel or ordinary alloy materials. Although the medical devices made of these materials can basically meet the requirements in terms of strength and rigidity, their performance is average. The finished medical device is relatively heavy
