The problem for affecting nuclear-magnetism to check after being connected using traditional titanium connection sheet and titanium nail.
The material of the plain film and cylinder of this device is resorbable polymeric materials, then the device is equally applicable to children
Patient, provides a kind of Cranial-bone-flap replacement and fixation product that can be used for children to neurosurgeon, using easy to operate, and carries
The high long-term effect of operative treatment, expands the use range of the device.
In the present embodiment, the plain film is flat cuboid, a length of 3-30 millimeters, a width of 1-15 millimeters, and thickness is
0.1-10 millimeters；The cylinder is rectangular cylinder or cylinder, the diameter and plain film of the width or cylinder of the rectangular cylinder
Width consistent, be a diameter of 2-10 millimeters of 1-15 millimeters, rectangular cylinder thickness or cylinder, rectangular cylinder or cylinder
Physical length be 2-20 millimeters.
More preferably, a length of 10 millimeters of the cuboid of the plain film, a width of 3 millimeters, thickness is 1 millimeter, 1 millimeter of thickness
Certain intensity can be both reached, and had been covered on skull surface and will not also seem that projection was felt, the edge of the plain film had been carried out
Slope process, can make flat cuboid be covered in skull surface incisura more small；The width of the rectangular cylinder or
The diameter of cylinder is consistent with the width of plain film, is 3 millimeters, a diameter of 2.5 millimeters of rectangular cylinder thickness or cylinder, square
The physical length of shape post or cylinder is 5.5 millimeters, and the length is typically smaller than skull thickness 2-3 millimeters, prevents embedded cylinder from dashing forward
Broken skull and stimulate Epidural cavity organize.
In the present embodiment, pawl is provided with the interior receipts side of the rectangular cylinder or the surface of cylinder is provided with screw thread
3, there is diminution gradual change at the tip 0.5-3 millimeters of rectangular cylinder or cylinder, gradual change angle is 5-35 degree, and tip diameter is 0.5-
5 millimeters.
More preferably, there is diminution gradual change at 1.5 millimeters of the tip of the rectangular cylinder or cylinder, gradual change angle is 10 degree,
Tip diameter is 2 millimeters.
The main purpose of the diminution gradual design of apparatus of the present invention is easy for embedded and prevents from slipping, and enhances the device solid
Fixed degree of stability, while the Cranial-bone-flap after fixed will not be subject to the pressure of vertical direction, equally it also avoid intracranial pressure and faces
Resistance during Shi Zengjia to brain tissue so that fixed result devoid of risk, if the making material of the device is degradable and lures
Lead the macromolecular material of skeletonization, then be exactly the excellent good product of children's neurosurgery.
Reset the be connected preparation method of device of above-mentioned Cranial-bone-flap is：Select a kind of high score for meeting medical embedded requirement
Sub- material is formed by injection or finishing impression.The condition for selecting injection or finishing impression is carried out in the dust proof workshop of ten thousand grades or hundred grades, with
Ensure the purity and clean level during injection or finishing impression so that the product of formation meets the technology of embedded type medicine equipment
Require.
1st, a kind of absorbable polymer material that meet medical embedded requirement is selected by being molded.This absorbable
Macromolecular material can be that polycaprolactone (PCL) polymer gradually forms tunnel and micropore in degradation process in vivo, be easy to
Gegenbaur's cell, the Gegenbaur's cell secretion ossein for growing into, the carrier bracket of the ossein (type i collagen) of secretion as skeletonization, body
Calcium ion and phosphate radical in liquid deposits on type i collagen fiber and assembles and be combined into new bone tissue.The reason for selecting injection exists
The material shape for meeting implantation human body requirement provided in current country's external enwergy is fine particulate, therefore, first according to the system of product
Female mold is designed as shape need, at temperature 60-85 DEG C, then carries out injection mo(u)lding.
2nd, a kind of macromolecular material finishing impression of the nonabsorable for meeting medical embedded requirement is selected to form.This non-absorbent
Macromolecular material can be a kind of novel high molecular polymer for ultra-high molecular weight polyethylene (PE), the external nineties at the end of the eighties
Just start to be applied to clinic, used as Srgery grafting material, there is light weight, good biocompatibility not to be absorbed, not conducted heat for which,
Satisfactory mechanical property, postoperative low repressive, do not affect CT, MRI to check, and titanium material checks there is different degrees of impact to MRI.
The material shape for being implanted into meeting of selecting that finishing impression is that country's external enwergy at present provides the reason for make human body requirement be plate-like, because
This, needs first to design 3-D graphic according to the making shape need of product, 3-D graphic is switched to three-dimensional data then and imports essence
Finishing impression shaping is carried out in the work computer of carving machine, is needed to select four axles or five-axle linkage according to the precision of product and space structure
Finishing impression equipment carry out the making of product.
