In, first perforate 1161, the second perforate 1162 and the 3rd perforate 1163 are three round holes of coaxial setting.It is described
The aperture of first perforate 1161 is more than the aperture of second perforate 1162.The aperture of second perforate 1162 is more than described the
The aperture of three perforates 1163.3rd perforate 1163 is used for partial receipt and the fixed screw 112.3rd perforate
1163 aperture is slightly larger than the external diameter of the screw 112, so that the screw 112 can be passed through.Second perforate 1162 is used
In partial receipt and the fixed sealing-plug 113.The aperture of second perforate 1162 is slightly less than the outer of the sealing-plug 113
Footpath, so that second perforate 1162 and the interference fits of sealing-plug 113.First perforate 1161 is used for partial receipt
With the fixed fluid sealant 114.
Fig. 4 is referred to, the sealing-plug 113 includes a cock body 1130.The cock body 1130 uses insulating elastic material system
It is standby.The shape of the cock body 1130 it is identical with the shape of the second perforate 1162 and with the interference fits of the second perforate 1162.
In one embodiment, the cock body 1130 is cylindrical silicon rubber.The present invention defines screwdriver when the cock body 1130 is used
The side of 20 insertions is the top of the cock body 1130, and the opposite side relative with the top is the bottom of the cock body 1130.
The top of the cock body 1130 has a groove 1131.The inside of cock body 1130 has a gap 1132.The groove 1131
Side be inclined-plane, so as to which the screwdriver 20 for being put into the groove 1131 is guided to the gap of the bottom of groove 1131
At 1132.The gap 1132 can make screwdriver 20 through the cock body 1130 and be restored to the original state after the extraction of screwdriver 20.
In one embodiment, the opening of the groove 1131 is wicker leaf shape and has two concave curvatures.The gap
1132 pass through the bottom centre position of groove 1131 and extend along the length direction of the groove 1131.The gap 1132
Width need according to the knife bar diameter design of screwdriver 20, it is ensured that screwdriver 20 through when the cock body 1130 will not be torn.
In one embodiment, the gap 1132 at least extends to relative another side from a side of the groove 1131.
In another embodiment, the two ends in the gap 1132 are extended respectively on the cock body 1130 outside the groove 1131.Can be with
Understand, when the cutter head of screwdriver 20 enter it is fashionable gradually can strut the gap 1132 to both sides along the guiding of the groove 1131,
So as to which the cock body 1130 for preventing cutter head from withstanding near the gap 1132 is stretched downwards, cause to be permanently deformed or tear.By institute
State the elastic deformation that the cock body 1130 near gap 1132 separately causes to both sides smaller, the shape in the gap 1132 will not be damaged
Shape, after screwdriver 20 is extracted, the gap 1132 can restore to the original state rapidly.
Fig. 5-6 are referred to, the bottom of the cock body 1130 has a hole 1133.The gap 1132 is by the groove
1131 connect with hole 1133.Described hole 1133 includes one first hole 1133a, one second hole 1133b and one the 3rd
Hole 1133c.The first hole 1133a, the second hole 1133b and the 3rd hole 1133c set gradually from inside to outside and
It is interconnected.Preferably, the first hole 1133a, the second hole 1133b and the coaxial settings of the 3rd hole 1133c.
The aperture of the first hole 1133a is slightly larger than the diameter of the knife bar of screwdriver 20, so that the first hole 1133a
The insertion of screwdriver 20 can smoothly be accommodated.The aperture of the first hole 1133a is much smaller than the internal diameter of the screw 112, from
And the screw 112 is not inserted in the first hole 1133a.Further, the space of the first hole 1133a formation
When can accommodate the insertion of the cutter head of screwdriver 20, the downward deflection of cock body 1130 near the gap 1132, so that this is downward
The cock body 1130 of deformation will not touch the hard end of screw 112.It is appreciated that the cock body 1130 as fruit part is deformed is clipped in
Acted in the middle of the cutter head of screwdriver 20 and screw 112 and by certain extruding force, then can cause the damage of the cock body 1130 of the deformation
It is bad.The aperture of the second hole 1133b is slightly larger than the external diameter of the screw 112, so as to house part screw 112.Institute
The aperture outline for stating the 3rd hole 1133c is less than the external diameter of the screw 112 and is more than or equal to the interior warp of the screw 112, from
And the screw 112 can be clamped.It is appreciated that when the screw 112 is screwed out counterclockwise, institute can be easier inserted upwards
State in the second hole 1133b.The side wall of the 3rd hole 1133c can clamp the screw 112, make the screw 112
Keep vertical state.Further, thickness of the side wall of the 3rd hole 1133c in the 3rd hole 1133c depth directions
It is very thin, usually 0.2 millimeter~0.4 millimeter.Because the sidewall thickness of the 3rd hole 1133c is very thin and second hole
1133b aperture is slightly larger than the external diameter of the screw 112, therefore, when the screw 112 is screwed out counterclockwise, both will not be from described
3rd hole 1133c side wall is painstaking, also will not be painstaking from the side wall of the second hole 1133b, described so as to prevent
The jack-up of sealing-plug 113 is come when screw 112 is screwed out counterclockwise.It is appreciated that the second hole 1133b and the 3rd hole
1133c depth selection has related to the length of the screw 112.In one embodiment, the length of the screw 112 is
2.0 millimeters, the second hole 1133b depth is 0.4 millimeter, and the depth of the 3rd hole 1133c is 0.3 millimeter.
Fig. 7-8 are referred to, in another embodiment, the sealing-plug 113 can also make Split type structure.Specifically, institute
Cock body 1130 is stated including a base 1130a, a core 1130b being arranged on base 1130a and the core is sheathed on
Sleeve 1130c on 1130b.The cylinder of sealing-plug 113 generally one.The base 1130a and the core 1130b are equal
To be round table-like.The height and diameter that the height of the base 1130a is much smaller than the core 1130b are more than the core 1130b
Diameter.The base 1130a is coaxially disposed and is integrally formed with the core 1130b.The sleeve 1130c is a hollow circle
Post.The interior diameter through equal to or slightly less than the core 1130b of the sleeve 1130c.The external diameter of the sleeve 1130c is equal to
The diameter of the base 1130a.The base 1130a and core 1130b is prepared using silicon rubber.The sleeve 1130c
It can be prepared using silicon rubber, can also the larger material preparation of the hardness such as metal or resin.The top tool of the core 1130b
Have with a groove 1131.There is the gap 1132 inside the core 1130b and the gap 1132 is by the core 1130b
It is divided into symmetrical two halves.The Split type structure can avoid the problem of inclined and easy tear is cut in the gap 1132 of centre.
Fig. 9 is referred to, the connection component 110 comprises the following steps when being connected：Have interior hexagonal recessed on screw 112
The one end in hole 1120 is inserted in bottom the second hole 1133b of sealing-plug 113 and clamped by the 3rd hole 1133c；
In the fixing hole 116 that sealing-plug 113 and screw 112 are put into the connector 111 together；Screwdriver 20 is worn from gap 1132
Cross sealing-plug 113 and insert in the interior hexagonal pit 1120 of the screw 112；The screw 112 is rotated and extracts screwdriver after fixing
20；The top of sealing-plug 113 and fixing hole 116 are sealed using fluid sealant 114.
It is appreciated that the connector 111 is not limited to the connector construction of above-mentioned impulse generator 11, as long as can coordinate
The connector that sealing-plug 113 of the present invention is used can realize the present invention.For example, for connecting stimulating electrode 12 and extension lead
13 connector.Therefore, as long as including the implantable medical device using the connection component of sealing-plug of the present invention in this hair
Within bright protection domain.
In addition, those skilled in the art can also do other changes in spirit of the invention, these are according to present invention spirit
The change done, should all be included in scope of the present invention.
