Description
Technical field
The present invention relates to medical fields, specifically a kind of for fixing the skull lock of skull.
Background technique
Skull lock is a kind of medical instrument of the fixation for Craniotomy bone flap, and Craniotomy skull lock can be rapidly
Reach the fixed requirement of bone flap clinic, saves operating time, human body can be chronically implanted.
Existing skull lock is usually to be equipped with two locking plates up and down and an intermediate lock core, and two locking plates and lock core are all
It is connected through a screw thread, rotates locking plate when fixed skull in this way so that cranium is fixed in two locking plate relative motions in turn
Bone.
But existing fastening is when in use, if Fig. 1 is existing skull lock construction, lower locking plate and upper collet and
Lock core can only be rotated relative to the direction of lock core, so when in use, sometimes since the surface of lock core and skull can not
Reach fitting, cause tightness not high, some even also needs second operation.
Summary of the invention
It is an object of the present invention to disclose a kind of skull lock of fixing compact regarding to the issue above, including lower locking plate, on
Locking plate and lock core, lock core connect upper collet with lower locking plate, which is characterized in that the upper collet center includes one second
Spill spin block, lock core pass through the second spill spin block, and it is upper collet sheet that the second spill spin block set, which has second rotating ring the second spill spin block periphery,
By the second shaft a connection, the second spill spin block and the second rotating ring can be with respect to second for body, the second spill spin block and the second rotating ring
Shaft a rotation, the second rotating ring connected with upper collet ontology by the second shaft b, and the second rotating ring and upper collet ontology can be with
It is rotated relative to the second shaft b, the center of the second spill spin block descend the back side of locking plate equipped with a knob slot relatively, in knob slot
Equipped with the knob that can be rotated around lock core, knob and lock core are threadedly coupled, and the skull lock is equipped with control handle rotation
Fastener, upper collet can be moved up and down with respect to lock core.
In the present invention, the symmetrical circular shape that the concrete shape of locking plate can be common, due to design of the invention, this hair
It is bright the shape of locking plate to be revised as asymmetrical shape, it such as can be a rectangle, square, and rectangular design
It can preferably to fix skull in the case where area is certain, and it is existing since locking plate and lock core can not freely turn
It is dynamic, it is typically only capable to enough circles.So the shape for the skull lock locking plate that the present invention preferably increases, can easily fix skull
Any position.
For skull since the curved surface of each position etc. is inconsistent, existing skull lock can not be fitted in bone surface completely sometimes,
Cause tightness not high, and skull lock of the invention can be freely rotated in two directions, it can be according to the surface shape of skull
Shape is preferably fitted in the surface of skull, increases the tightness of skull, avoids since the not tight bring of skull lock is a series of
Problem.
When in use, especially when upper collet is not symmetrical, asymmetric upper collet is cannot by the present invention
It is enough arbitrarily to rotate, so upper collet and lock core of the invention be instead of such as the threaded connection of traditional approach, it is common can on
Lower movement, if upper collet central hole location be greater than lock core section, at this time need on the second spill spin block be equipped with one and
The knob that lock core is threadedly coupled controls upper collet by external strength turning knob and lower locking plate clamps skull.
As an improvement, knob is equipped with recess portion, fastener is equipped with the protrusion for being caught in recess portion, and fastener can be traditional
Fastener, and the lock core that can fracture.
In practice, single upper collet using rotatable design can so that tightness increase, but in order to
Fastening performance is further provided for, the design similar with upper collet is usually also used in lower locking plate, lower locking plate center includes one
A first spill spin block, lock core pass through the second spill spin block, and the first spill spin block set has the first rotating ring, under the first spill spin block periphery is
Locking plate ontology, the first spill spin block and the first rotating ring are connected by first rotating shaft a, and the first spill spin block and the first rotating ring can phases
First rotating shaft a is rotated, the first rotating ring) it is connected with lower locking plate ontology by first rotating shaft b, the first rotating ring and lower locking plate sheet
Body can be rotated relative to first rotating shaft b, and wherein lock core and the first spill spin block may be a fixed connection and be also possible to integrated molding.
And in order to increase the compactness and stability maintenance of locking plate and skull under upper collet, upper collet and lower locking plate to
Increase can be set up or be all provided on opposite and skull frictional force further provides for the partial structurtes of stability, such as can be circular cone
The protrusion of property, is also possible to the structure of various recess portion injustice.
The present invention can also be led to for the lock core that fractures using the turn of bilge being equipped in the end of lock core for the lock core that fractures
Existing fastener is crossed to fracture.
Excellent effect of the invention be but be not limited to can use various shapes lock plate structure, fastening when not
It needs to rotate locking plate, and the angle of locking plate can be rotated when needing to be preferably bonded with skull, specific
When use, spill spin block, rotating ring, locking plate ontology thickness are most preferably designed with tightness, in general, spill spin block thickness
Less than rotating ring, rotates ring thickness and be less than locking plate ontology.
