Description
Technical field
The utility model relates to skull recovery technique fields, repair more particularly, to a kind of skull with groove structure
Multiple sticking patch.
Background technique
Cranioplasty is a kind of brain for leading to skull defeci for brain trauma and operation of opening cranium etc. and being repaired to it
The common operation of surgery.The patient of skull defeci often has the mental burdens such as heavier sense of insecurity, and can cause headache, it is dizzy,
Be afraid of the syndromes such as vibration, the time of skull defeci is longer, and the incidence of skull defect syndrome and subsequent brain damage is higher.For
Restore the airtightness of cranial cavity, physiological intracranial pressure is kept to stablize, mitigates skull defect syndrome, to skull defeci diameter 3
Centimetre or more, no muscle covering, no contraindication person should carry out skull repairing.It is generally acknowledged that repairing in post-craniotomy 3 ~ 6 months is
Preferably, because being the repairing to skull tissue, material is selected to require have very high biocompatibility first, and needs while guarantees
Certain strength and stiffness both provided protection strong enough, also to meet the needs of moulding in art, and it is satisfied to reach profile reparation
Effect.
In recent years, polyether-ether-ketone, the high molecular materials such as English name polyetheretherketone (abbreviation PEEK) by
In the good biocompatibility of material, can complicated plasticity, excellent mechanical, protective performance is good, and postoperative comfort level is high, gradually at
For the recent tendency of materials for use in skull-fixing.The main stream approach applied at present is that self-taped type titanium is added to follow closely using strap in cranium jawbone
Sticking patch and Preserve selef-cranium are repaired to connect the skull of PEEK material production, but is found in use process: when self-taped type titanium nail exists
When squeezing into PEEK skull repairing piece, due to PEEK material have excellent toughness, titanium nail entry site material around titanium follow closely to
Upper irregular tilting, and then the sinking of strap and titanium nail is hindered, it eventually leads to fixed plate and titanium nail raises upward, it cannot
It is bonded skull and repairs patch faces.According to clinic feed back, fixed plate and titanium nail raise upward, on the one hand influence skull repairing effect
Fruit is not beautiful enough, and another aspect boss and the skin covered will form friction, is prone to wear skin and inflammation is caused to be sent out
It is raw.
Utility model content
The technical problems to be solved in the utility model is to overcome existing skull to repair sticking patch to be easy to appear in use
It tilts, repair efficiency unsightly, is easy to cause the defect and deficiency of skin abrasion and inflammation, provide a kind of with groove structure
Skull repairs sticking patch.
The utility model above-mentioned purpose is achieved through the following technical solutions:
A kind of skull reparation sticking patch with groove structure, skull are repaired sticking patch and are prepared by plastic material, and the skull is repaired
Multiple patch faces are equipped with several first grooves, and first groove location is beaten with when connecting Preserve selef-cranium and skull reparation sticking patch
The self-tapping screw position entered is corresponding.
The first groove that skull repairs patch faces is used as the fixed hole position of self-tapping screw, i.e. screw position groove, self tapping
Type screw can repair sticking patch generation in skull when in use and irregularly tilt upwards around titanium nail, pass through setting screw position groove
It can be very good to accommodate these irregular tiltings upwards, so that strap connection skull repairs sticking patch and self cranium in cranium jawbone
The skull modification patch faces of recessed circumferential can be bonded when bone, whole surface keeps fitting smooth, solves self-tapping screw
The problem of cannot obtain flat surface because of periphery material tilting in the use of plastic material.The number of first groove matches institute
Screw number, several first grooves are distributed in the surrounding of skull patch.
Preferably, first groove is the circle of 1.5~2.8mm of diameter, and depth is 0.3 ~ 0.4mm.Circular groove with
Tapping screw matches, and being usually used in the fixed self-tapping screw of skull repairing system is circle, in use around screw
The protrusion of generation also substantially surrounds circle, and round deep hole, which can more coincide, accommodates convex portion.
Preferably, the skull repairs patch faces and is also provided with the second groove, second groove location with connect oneself
The position that body skull and skull repair strap in cranium jawbone used when sticking patch is corresponding, and second groove surrounds first
Groove, first bottom portion of groove are deeper than the second bottom portion of groove.
The upper surface that above-mentioned skull repairs sticking patch has dual groove design, and the first groove is corresponding with self-tapping screw；
Second groove is corresponding with strap in cranium jawbone, for accommodating the groove of strap in cranium jawbone.Specifically, first is recessed
Slot position is in the bottom range of the second groove, i.e., screw position groove is located in cranium jawbone in the recess of strap position, so that cranium
Strap can be completely embedded into skull and repair sticking patch and flush with the skull upper surface of the second groove vicinity in jawbone, further
The regularity of appearance is improved, the abrasion to contact skin is mitigated.
Preferably, the length of second groove is 7 ~ 9mm, and width is 6 ~ 8mm, and depth is 0.6 ~ 0.7mm.
Preferably, the skull repairs sticking patch and forms to obtain by poly aryl ether ketone material.The polyethers that the utility model uses
Ether ketone material has better biocompatibility compared with titanium net, avoids stimulation of the metal otter board to skull tissue, generates
Allergy, rejection, and have the features such as good intensity, toughness, preferred, polyethers ether ketone.
Preferably, it is arc smooth edge that the skull, which repairs the edge of sticking patch,.The design of arc smooth edge can be to avoid
Because sharp component is to skull or the possible damage of its hetero-organization.
Preferably, the skull is repaired and is provided with through-hole in patch body.The setting of through-hole can be conducive to Cerebrospinal fluid
Discharge, effectively reduces hypohydrops.
It is highly preferred that the aperture of the through-hole is 2 ~ 3 mm, through-hole spacing is 10 ~ 15 mm.
Compared with prior art, the utility model has the beneficial effects that
The utility model provides a kind of skull reparation sticking patch with groove structure, is set by first groove on surface
Meter can be very good to accommodate the kick generated when self-tapping screw is fixed to be used, strap in cranium jawbone pasted
The skull for closing recessed circumferential modifies patch faces, guarantees the smooth of entire repairing surface, skull repairs sticking patch can also be further
Second groove is set, strap in cranium jawbone is accommodated by the second groove, skull is repaired sticking patch and can preferably be connected self
Skull, the compressing to reparation position soft tissue is reduced without obvious protrusion in the upper surface of skull entirety after connection, and reduces edge
Protrusion situation and it is more attractive, thus avoid patient because repair position soft tissue abrasion inflammation by pain torment and reduce different
Object sense mitigates the psychological burden of patient significantly, can be widely applied to skull and repairs in clinical trial.
