The pedicle screws are configured with a recess (58) formed therein having threads therein for threaddly enaging a set screw (90).
A threaded set screw may be used to secure the bone screw within the locking plate.
The 'setscrew-like' fastener only interfaces with the elongated member.
Tightening of the clamping screw within the clamping screw orifice removably joins the barrel to the barrel housing.
The closure may also be in the form of a set screw and closure combination, with the set screw including a breakaway driving head and a removal head with a polyhedral shaped external surface.
The device (10) further includes a set screw (20) and a rod connector (14).
The tool comprises a means for limiting the force applied to the core by the set screw (13, 14).
A pair of flats (50) are each formed in the shank portion(34) for engaging the set screws (fig.3 : 44) when the arbor (fig.1 : 26) is configured to have the set screws (fig.2 : 44).
The screws are preferably set screws, comprising a guide structure (9), a threaded structure (10), a fall-away prevention structure (11), and a wrenching structure (12).
The bone anchor also includes a locking cap(102) that has a main body (900) and a set screw (1000).
The pressure spiral conveyor (4) is provided with cooling means (16) and/or the body (1) is provided with cooling means arranged in the zone of the pressure spiral conveyor (4).
A pressure chamber of which the volume can be varied by turning the pressure screw (4) is formed in a bore (18) of the housing (2).
Due to the pressure of the nut material in the strength of lower than the pressure screws, it is only necessary to check the pressure of the nut screw bending and shear strength.
Accordingly, the axle hole in the bottom part of the pressing screw has a corresponding segmented structure.
A boss (71) is formed at the centre inside the top cap, pressing onto or pressing close to a top end plane (33) of the pressing screw.
A terminal end (32'') of the pressure screw (4) delimits a second pressure chamber (37), and the first and second pressure chambers (33, 37) and the piston space (17) are fluidically connected to one another.
The screw stop position of the stator (1a) of the motor (1) is displaced at a predetermined angle with respect to the pressing/fixing screw (11) around the axis of the motor (1).
A special pressure screw make immovable the guide during the cutting operation.
The pressure screw (4) has, over a lengthwise portion, a radial spacing from the wall of the bore (18), with the result that a first pressure chamber (33) is formed.
The locking mechanisms (2) include a pressing screw (2-3) with a bottom plate and a nut (2-4).
The gearbox (11) is modified by a 'blister' (12), which houses the pressure screw and housing (14).
The web collar is positioned on a segment of casing and is secured in place with set screws.
The locking mechanism (100) includes a body (102), an insert (108, 308), a rod seat (110, 310) and a set screw.
The distal surface of the outer set screw has a shape that is complementary to the shape of the proximal surface of the compression member.
Therefore, the fastening force of the pedicle fixation screw and the set screw is increased, the movement of the spine rod is prevented in case of the realignment of the pedicle, and a spine can be realigned stably.
