Manufacturing method of skull lock

Abstract

The invention discloses a manufacturing method of a skull lock. The method comprises the following steps of heating a first material to a molten state; mixing a second material into the first material in the molten state, and uniformly mixing; waiting for cooling and solidification of the molten mixture; preparing an osteogenesis part through a forming method, matching the osteogenesis part with a locking part to form the skull lock, and after the locking part fixes a bone flap and a skull opening in the first direction, and forming a plurality of induction holes which exist in the osteogenesis part of the gap between the bone flap and the skull and in a penetrating mode in the second direction different from the first direction induce bone cells at the two ends of the opening of the bone flap and the skull to grow towards each other so as to form bone anchors.

Description

technical field [0001] The invention relates to the medical field related to the neurosurgery skull, in particular to a method for making a skull lock. Background technique [0002] In neurosurgery, under some commonly used surgical methods, the patient's skull needs to be cut open, and the cut bone is called a bone flap, which needs to be put back to its original position after surgery to achieve subsequent bone healing. Certain immobilization devices are required to prevent displacement of the bone flap until bone union is complete. [0003] CN209564187U relates to the technical field of neurosurgery medical equipment, specifically a skull lock, comprising a fixed locking piece, a movable locking piece, a cable tie, a handle, a top tightening column and a return spring; the lower end and the upper end of the cable tie are connected with the fixed lock The lock piece is fixedly connected with the handle; the movable lock piece is provided with a lock hole matching the cabl...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the existing technology can only realize the fixation of the bone flap. In order to guide the process of bone growth, any irregular growth of the bone will cause the bone to heal after bone healing. In addition, if absorbable materials are used in the design, the cranial lock will not be able to provide sufficient stable support to ensure the position of the bone flap in the later stage of bone healing. At this time, the bone flap is still prone to displacement , so that the bone healing results fall short, and the existing technology cannot realize the stable support of the bone flap throughout the bone healing period and the uniform formation and guidance of the direction and strength of the bony bone.
