Abstract

The invention belongs to the technical field of medical titanium alloys, and relates to a medical ultrasonic knife Ti7Al4Mo titanium alloy wire and a preparation method thereof. According to the preparation method, high-temperature forging and low-temperature rolling processes are effectively combined, so that the strength and plasticity of the material are improved at the same time; the method specifically comprises the following steps: heating a cast ingot to an alpha + beta two-phase region, and carrying out multi-heating-number reversing upsetting forging, precision forging, straightening and middle multi-time surface defect coping to obtain a bar blank; through deformation heat caused by high-frequency forging in the precision forging process, heat of the material is dispersed more uniformly, the structure and mechanical properties of the Ti7Al4Mo titanium alloy material are effectively improved, and the Ti7Al4Mo titanium alloy material can be widely applied to the fields of ultrasonic knife heads, jet engine parts, missile forgings, weaponry and the like and has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of medical titanium alloys and relates to a medical ultrasonic knife, in particular to a medical ultrasonic knife Ti7Al4Mo titanium alloy wire and a preparation method thereof. Background technique [0002] Clinical ultrasonic scalpels can be divided into soft tissue ultrasonic scalpels and hard tissue ultrasonic scalpels according to the surgical objects. They are mainly used in cataract emulsification, liver and gallbladder tumor suction, liposuction, bone cutting, cutting and coagulation, etc. Compared with the traditional high-frequency electric knife and mechanical clamp, the medical ultrasonic knife has the characteristics of low frequency, large amplitude, continuous work, high precision, less hemostasis, no burns, and quick recovery. [0003] Many scholars and institutions at home and abroad have conducted research on ultrasonic scalpels and have extended them to clinical operations. In the past two ...
