Abstract

The invention belongs to the technical field of medical titanium alloy bars, and provides a TC4ELI titanium alloy for an ultrasonic scalpel and a production method of the titanium alloy bar. The TC4ELI titanium alloy specifically comprises the following material chemical components: 5.5-6.5% of Al, 3.5-4.5% of V, 0.15-0.25% of Fe, 0.1-0.5% of Si, 0.08-0.13% of O, 0-0.05% of C, 0-0.03% of N, 0-0.005% of H, and the balance of Ti and inevitable impurity elements in titanium sponge. The raw materials are subjected to three times of vacuum consumable smelting, so that the components are uniform and consistent without internal defects. The blank is subjected to a series of later hot working and heat treatment, and the performance meets the performance requirement of the ultrasonic scalpel. According to the method, the steps of composition, hot working and heat treatment are controlled step by step, the titanium alloy bar with the best matching strength, plasticity, toughness and fatigue performance is prepared, the ultra-high cycle fatigue of the ultrasonic scalpel is improved, the service life is prolonged, the scalpel breaking phenomenon in the operation process is avoided, and the method has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of medical titanium alloys, in particular to a production method of TC4ELI titanium alloys and titanium alloy rods used for ultrasonic scalpels. Background technique [0002] At present, the working principle of the ultrasonic scalpel is to convert the electric energy provided by the ultrasonic generator into high-frequency mechanical vibration through the ultrasonic transducer, and then amplify the amplitude of the mechanical vibration through the ultrasonic horn, and the amplified mechanical vibration is transmitted to the transformer. The knife rod connected with the radial rod and the end part finally realize the function of cutting tissue by contacting the biological tissue. The ultrasonic scalpel has the characteristics of low frequency, large amplitude, and continuous operation. It also has the advantages of high precision, neat surgical incision, fast hemostasis, small thermal burn area, and less smo...
