Flexible forming device and forming method of amorphous alloy skull repairing body

Abstract

The invention belongs to the field of flexible forming of skull repairing bodies, and discloses a flexible forming device and a forming method of an amorphous alloy skull repairing body. The device comprises clamping units and a forming unit, wherein the clamping units are symmetrically arranged on the side surfaces of the forming unit; the forming unit comprises a tool head and laser devices; themultiple laser devices are uniformly arranged on the upper end of the tool head in the peripheral direction and are used for heating a to-be-machined zone before the to-be-machined zone below the tool head is machined by the tool head, so that a amorphous alloy plate of the to-be- machined zone is located in a supercooling liquid phase zone between a glass-transition temperature and an initial crystallization temperature; and the tool head rolls and forms the to-be-machined amorphous alloy plate along a preset trajectory layer by layer, so that flexible forming of the to-be-machined amorphousalloy plate is realized. Through the flexible forming device and the forming method, the biological compatibility of the obtained skull repairing body is good; bouncing of the repairing body is avoided; and the success rate of skull repairing surgery is improved.

Description

technical field [0001] The invention belongs to the field of flexible shaped skull repair body, and more specifically relates to a flexible forming device and a forming method of an amorphous alloy skull repair body. Background technique [0002] The skull is an important part of protecting the human brain. Skull repair surgery is usually a surgery for the treatment of skull defects. When the maximum diameter of the skull defect exceeds 3cm, skull repair surgery is required. The most important link is the manufacture of the skull prosthesis. [0003] At present, the cranial prosthesis is mainly made of titanium mesh, and amorphous alloy plate is rarely used. Because the titanium mesh material is prone to rebound during the forming process, most of the cranial prosthetic bodies made of this material have poor forming accuracy and cannot be used. Fully fit the patient's wound; [0004] As for the preparation method of the skull repair body, the common methods include manual m...

AI Technical Summary

Problems solved by technology

Hydraulic method uses liquid to obtain high pressure, which is expensive

The main problem of the multi-point forming method is that the machining accuracy is limited by the size of the basic body group, which cannot meet the accuracy requirements

For the skull repair body, the structure of the repair body required by different patients is different. Using the above methods, it is necessary to tailor the mold to meet the needs of different patients. On the one hand, the manufacturing cost is greatly increased, and on the other hand It also prolongs the manufacturing time and greatly reduces the manufacturing efficiency, which ultimately affects the success rate of patients' operations.
