Embodiment 1

[0049] The skull lock of this embodiment adopts structure one, wherein the middle layer of upper and lower lock plate materials is taken from rolled pure magnesium (purity is 99.99%) plate. A Φ5mm×0.8mm locking piece with a toothed edge is prepared by stamping, and 4 first through holes and 4 second through holes with a diameter of Φ0.5mm are drilled. The upper and lower ceramic layers of the locking piece are made of original It is obtained by a high-temperature ceramic method, and the thickness of the obtained ceramic layer is 20 μm. The connecting wire is made of pure magnesium (99.99% pure) wire with a diameter of 0.4 mm to connect the upper and lower locking pieces. The functional wire is made of pure magnesium (purity: 99.99%), the cross section is circular, the diameter is 1mm, and the diameter of the third through hole is 0.5mm. The beams are arranged continuously, with a thickness of 0.2 mm and a width of 0.5 mm. The surface of connecting wire, functional wire and b...

Embodiment 2

[0052] The skull lock of the present embodiment adopts the second structure, wherein the middle layer of the upper and lower lock plate materials is taken from rolled state ZK60 magnesium alloy (purity is 99.9%) plate. A Φ8mm×1mm locking piece with a 0.5mm diameter limiter and a toothed edge is prepared by punching, and 4 first through holes and 4 second through holes with a diameter of Φ0.5mm are drilled, and the locking piece is The upper and lower ceramic layers are formed by an in-situ high-temperature ceramic method, and the thickness of the obtained ceramic layer is 50 μm. The connecting wire is made of polylactic acid wire with a diameter of 0.4mm, which connects the upper and lower locking pieces. The functional wire is made of ZK60 magnesium alloy (purity: 99.9%), the cross section is circular, the diameter is 1.5mm, and the diameter of the third through hole is 0.5mm. The beams are arranged continuously, with a thickness of 0.3 mm and a width of 0.6 mm. The surface...

Embodiment 3

[0055] The skull lock of the present embodiment adopts the third structure, wherein the middle layer of the upper and lower lock plate materials is taken from a rolled magnesium-strontium alloy (purity is 99.9%) plate. The Φ12mm×1.5mm locking piece with toothed edge is made by stamping method, the height of the middle protrusion of the lower locking piece is 2mm, and the width is 2mm. The upper and lower locking pieces are drilled with 4 first through holes with a diameter of Φ0.7mm and 4 second vias. The upper and lower ceramic layers of the locking piece are obtained by electrodeposition, and the thickness of the obtained ceramic layer is about 50 μm. The connecting wire adopts magnesium-strontium alloy (purity is 99.9%) wire material with a diameter of 0.6mm, and connects the upper and lower locking pieces. The surface of connecting wire and functional wire is prepared with calcium phosphorus coating by electrodeposition method.

Abstract

The invention provides a degradable skull lock capable of improving skull healing ability, which aims to solve the problems of skull defect rapid healing and infection. Each lock plate of the skull lock adopts a degradable composite material with a sandwich structure; a connecting filament adopts a pure magnesium or magnesium alloy or degradable macromolecular material; the upper lock plate and the lower lock plate are locked by a connecting filament mode; and a functional filament is designed between the upper lock plate and the lower lock plate, and a skull gap is filled with the functional filament. The degradable skull lock capable of improving the skull healing ability can solve the problem that the existing implant material has low bioactivity and the problem of infection, can accelerate skull healing and reduce the occurrence rate of infection, and can be biodegraded.

Description

technical field [0001] The invention relates to a cranial lock for neurosurgical treatment, and in particular provides a degradable cranial lock that improves the healing ability of the skull. Background technique [0002] Skulllock is a medical device used for bone flap fixation after craniotomy. After craniotomy, the cranial lock can quickly meet the clinical fixation requirements of the bone flap. It is easy to operate, fast to tighten, and firmly clamped, saving operation time. [0003] At present, the cranial locks used clinically are divided into two types according to the material, which are non-absorbable and absorbable. The non-absorbable cranial lock is made of titanium alloy. Due to its biological stability in the body, it needs to exist in the human body for a long time. This cranial lock is not suitable for children before puberty. For adults, the long-term existence of cranial lock can also cause a certain degree of discomfort. Absorbable cranial locks are m...
