Abstract
The utility model discloses a gridding-shaped metal skull plate. A plurality of bolt holes are arranged at the periphery of the skull plate; the skull plate is provided with three-dimensional meshes which comprise a plurality of vertical through holes distributed from the upper surface to the lower surface of the skull plate and a plurality of transverse pore canals communicating with part or all of the through holes. When the sick bone of a patient is grafted into the gridding-shaped metal skull plate, the marginal bone cells of the bone window contacting the skull plate can grow into the three-dimensional meshes in an embedding way to circle and be locked so as to achieve the effect of effectively preventing the grafting body from separating and loosening from sclerotin. In addition, due to the structure of the three-dimensional meshes, the skull plate can be made to be thicker than the existing metal netting, and the skull plate has better rigidity and favorable goodness of fit with the surface of the skull without molding clipping. In the use, the skull plate is less influenced by the temperature of the environment and is not easily deformed by heat or cold.

Background technology
Become common neurocranial surgery treatment case by local disappearance of the caused skull of situations such as tumor operation, severe trauma, malformation correction and reparation thereof.This type of operation of great majority at present uses the wire netting sheet of shaping to substitute the skull at disappearance position, generally need be in operation to the wire netting sheet cut out, bending, moulding or the like reprocessing be to fit with skull surface as far as possible, so the wire netting sheet is generally selected thin softer metal material for use.This wire netting sheet can produce distortion as the alternative rigidity deficiency that exists in the part of skull under unexpected external force effect, serious meeting injures scalp or cerebral tissue.
The utility model content
The purpose of this utility model provides a kind ofly to be had strong rigidity and need not the latticed metal skull plate of moulding reduction with the good goodness of fit of skull surface.
For achieving the above object, this utility model is taked following design:
A kind of latticed metal skull plate, it is characterized in that, this skull plate periphery is provided with several screw holes, and this skull plate has three-dimensional mesh, and this three-dimensional mesh comprises the horizontal duct of several the vertical through hole to lower surface and connected component or whole described through holes from skull plate upper surface.
Described three-dimensional mesh is abound with in whole skull plate.
Described three-dimensional mesh is arranged in the middle part of this skull plate, and this skull plate periphery is ring-type compact metal support portion, and described screw hole is located on the described ring-type compact metal support portion.
Described three-dimensional mesh is strip and block and distributes, this skull plate periphery is ring-type compact metal support portion, this skull plate middle part has the strip compact metal support bar integrally formed with ring-type compact metal support portion, and described screw hole is located on the described ring-type compact metal support portion.
Described horizontal duct is monolayer duct or multilamellar duct.
It adopts medical metal to make.
The surface of described three-dimensional mesh has hydroxyapatite coating layer, medical plastic coating or medical silica-gel coating.
The utility model has the advantages that:
1, the latticed metal skull of this utility model plate, this skull plate periphery is provided with several screw holes, this skull plate has three-dimensional mesh, and this three-dimensional mesh comprises the horizontal duct of several the vertical through hole to lower surface and connected component or whole described through holes from skull plate upper surface.Therefore, patient understands in the chimeric three-dimensional mesh of growing into and around locking at the bone window edge osteocyte that contacts with the skull plate after suffering from this latticed metal skull plate of bone implantation, reaches to prevent effectively that muchly implant and sclerotin break away from loosening effect.In horizontal duct is under the situation in multilamellar duct, the skull plate thickness will be much larger than existing wire netting sheet thickness, and this skull plate has rigidity preferably, and in using because thereby this skull plate thickness has strengthened the distance between cerebral tissue and scalp greatly, make interior tissue be subjected to the external temperature environmental effect less, and skull plate self also is difficult for taking place cold and hot distortion.
2, the latticed metal skull of this utility model plate, wherein three-dimensional mesh is arranged in the middle part of this skull plate, and this skull plate periphery is ring-type compact metal support portion, and screw hole is located on the ring-type compact metal support portion.Therefore, big for example tension, resistance to compression, bending resistance, antitorque of mechanical loading can be born in ring-type compact metal support portion.
3, the latticed metal skull of this utility model plate, wherein three-dimensional mesh are strip and block and distribute, and this skull plate periphery is ring-type compact metal support portion, and this skull plate middle part has strip compact metal support bar, and screw hole is located in the metallic support portion.The existence of ring-type compact metal support portion and strip compact metal support bar makes this utility model skull plate can bear big for example tension, resistance to compression, bending resistance, antitorque of mechanical loading.
4, the latticed metal skull of this utility model plate, wherein laterally the duct is the multilamellar duct, if when need not to bear big mechanical loading because of plate body size position less or that implanted, laterally the monolayer duct also can be adopted in the duct.
5, the latticed metal skull of this utility model plate, the brain temperature difference influence that causes in order to improve metal heat-conducting rate height has hydroxyapatite coating layer or medical plastic, medical silica-gel coating on the surface of skull plate plate body and three-dimensional dictyosome.
