The elastic handgrip bar 4 of root, at least 3 handgrip bars 4, which are uniformly distributed, is fixed on the end that handgrip pushes away column 2, and it is fixed that handgrip pushes away column 2
There is one end of handgrip bar 4 to be inserted into from outer housing import 1-1, and is through at outer housing 1；In outer housing 1, the contraction of handgrip bar 4 is placed in
In outer housing 1, when handgrip, which pushes away column 2, to be fixed with one end of handgrip bar 4 and be pierced by from outer housing outlet 1-2, all handgrip bars 4 are together
It flicks；The handgrip, which pushes away column 2 and is not fixed to one end of handgrip bar 4, is connected with elastic plate 5, and 5 one end of elastic plate is fixed on handgrip and is pushed away
On column 2, the other end is pierced by outer housing outlet 1-2；Setting in column 2, which is pushed away, in handgrip pushes away column through-hole, support rod 3, which inserts in, to be pushed away in column through-hole,
And support rod 3 can push away column 2 from handgrip and be fixed with one end of handgrip bar 4 and be pierced by.
Outer housing 1 is transparent shell, and outer housing 1 is equipped with graduation mark 7 close to the outer wall of import, is convenient for by graduation mark 7
Nipper device stretches in the position for needing the skull base defects leak being moved under accurate perception nerve endoscope；It is arranged on handgrip bar 4
Several sawtooth enhance chucking power of the patching material on handgrip bar；Handle 6 is set in the end of support rod 3, facilitates and pushes support rod 3,
Meanwhile several suction hole 3-1 are set in one end that support rod 3 faces out housing outlets 1-2, suction tube 3-2 is also set up in support rod 3,
One end of suction tube 3-2 and several suction hole 3-1 are penetrated through, and the other end is pierced by the handle 6 of 3 end of support rod 3 and support rod, be pierced by
The external negative pressure device of suction tube 3-2 of 3 end of bar 3 and support rod.Water-filled pipe 8 is equipped on outer housing 1, water-filled pipe 8 passes through
Outer housing 1 is worn, it is convenient that repairing skull base defects leak position is rinsed during surgery, for rinsing surgical field of view in art.Outside
Shell 1 and handgrip push away column 2 and are provided with the equidirectional one end of elastic plate 5 setting outer housing handle 9, are arranged on elastic plate 5 several
Several handle limit holes are arranged on outer housing handle 9 for elastic plate limit hole, and several elastic plate limit holes, several handles limit
Hole corresponds, and also sets up spacer pin 10, spacer pin 10 is successively through at any one elastic plate limit hole and any one handle
Limit hole, so that elastic plate 5 is fixed on outer housing handle 9, elastic plate 5 can not be moved, when spacer pin 10 is from elastic plate 5, outer
When shell handle 9 takes out, elastic plate 5, outer housing handle 9 are separated, and elastic plate 5 can move；Pass through outer housing handle 9 simultaneously
Facilitate nipper under hand nerve probe scope.
In use, be sandwiched in the soft patching material that basis cranii needs is repaired on the handgrip bar 4 that handgrip pushes away on column 2, so that
Patching material is sandwiched between handgrip bar 4 and handgrip bar 4；Pull outward elastic plate 5, and the outer shipper pole of elastic plate 5 moves handgrip push rod 2 and bounces back to
In outer housing 1, at the same time, handgrip, which pushes away the handgrip bar 4 on column 2 and also starts Stepwize Shrink, enters outer housing 1, and patching material is pressed from both sides
It holds and steps into outer housing 1；
Sometimes clamping does not enter in outer housing 1 soft patching material completely, and handgrip, which pushes away, has porous attraction on column,
Under vacuum suction, outer housing can be completely in reach patching material by the further inspiration outer housing 1 of patching material
It is interior.That is, when in use, be sandwiched between handgrip bar 4 and handgrip bar 4 in patching material, pull outward elastic plate 5 when, handgrip pushes away on column 2
Handgrip bar 4 also start Stepwize Shrink and enter outer housing 1, patching material is clamped to be stepped into outer housing 1, while being started negative
Pressure device, negative pressure device through suction tube 3-2, several suction hole 3-1 adsorb patching material so that patching material absorption be fixed on to
Bar 3 faces out one end of housing outlets 1-2, it is ensured that patching material is moved completely as handgrip bar 4 bounces back in outer housing 1 in outer
In shell 1.
Then, nipper device under nerve endoscope is stretched in the position for needing the skull base defects leak being moved to, outer housing goes out
Mouth 1-2 pushes elastic plate 5 against repairing skull base defects leak to be repaired, and handgrip is driven to push away the outside housing outlets side 1-2 of column 2
To movement, when handgrip pushes away column 2 and is fixed with one end of handgrip bar 4 and is pierced by from outer housing outlet 1-2, all handgrip bars 4 are gradually flicked,
So that handgrip bar 4 discharges clamping to patching material, patching material gradually the swelling top for falling into repairing skull base defects leak, under
Side；Then support rod 3 is pushed, support rod 3 is pushed away in column 2 from handgrip and is pierced by, and resists patching material；Then it pulls back elastic plate 5, drives handgrip
It is mobile to push away 2 direction outside case entrances 1-1 of column, until handgrip pushes away the handgrip bar 4 on column 2 and is contracted in outer housing 1, due to support rod
4 resist patching material always, so that patching material be effectively prevent to return in outer housing 1 with when handgrip bar 4 is shunk；Finally again
Nipper device under whole nerve endoscope is removed from basis cranii position, patching material perfection is realized, is uniformly distributed in skull base defects
Leak upper and lower parts reach patching material in skull base defects leak caulked shape effect.
