Shaping method of titanium alloy medical inner fixing plate

Abstract

The invention discloses a shaping method of a titanium alloy medical inner fixing plate. The shaping method comprises the steps that 1, obtaining an existing bone tissue three-dimensional virtual model of a target patient; 2, simulating a bending shape of a virtual inner fixing plate attached to the bone tissue three-dimensional virtual model in a virtual environment; and step 3, extracting the spatial characteristic information of the bending shape of the virtual internal fixing plate obtained in the step 2, and driving a chuck of a bending mechanism to practically bend a standard part entityof the titanium alloy internal fixing plate by utilizing the obtained spatial characteristic information to obtain the titanium alloy medical internal fixing plate capable of being used for the target patient. The bending efficiency and the attaching precision of the titanium alloy medical internal fixing plate can be improved, repeated bending can be reduced, metal fatigue can be avoided, meanwhile, the preoperative preparation time can be shortened, and the operative preparation cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a shaping method of a titanium alloy medical internal fixation plate. Background technique [0002] Due to traffic accidents, falls, bumps and other traumatic factors, human bone tissue will be broken, fragmented or partially lost. Bone tissue lesions (benign and malignant tumors, etc.) can cause bone tissue morphology destruction or loss of function, and medical personnel have to incise or resect the lesioned bone tissue during disease treatment, which results in the destruction of bone tissue continuity. The incompleteness of bone tissue will affect the corresponding functions of the human body. For example, the incompleteness of the jaw not only affects the beauty of the patient's face, but also directly affects the patient's chewing, speech and other functions, affecting the patient's physical and mental health. [0003] For the defect or loss of bone tissue, it is n...

Problems solved by technology

[0007] 1. Bending the titanium plate before the operation needs to make the target bone tissue printing model entity of the patient. Before the doctor bends the titanium alloy internal fixation plate, there is no suitable way to know the bending shape of the titanium alloy internal fixation plate, and can only rely on the operation experience, so it takes longer

Preoperative high-precision bending takes an average of nearly 2 hours; if it is bent quickly during the operation, the fitting accuracy with the target bone tissue will be extremely l
