Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
" horizontal stroke " or " perpendicular " herein all sets for convenience of narration, is not the restriction to the technical program structure.
As shown in Figure 1 to Figure 3.
Multipurpose dilator in a kind of posterior spinal operation, including opening frame and retractor.The opening frame includes L-shaped
Fix bar 8 and the mobile bar of straight rod-shaped 1.Lived by a contiguous block 3 and the horizontal edge of the fix bar 8 one end of the mobile bar 1
Dynamic connection, makes the mobile bar 1 be in the fix bar 8 in a plane, and can be moved along the horizontal edge.
The retractor includes hook retractor 7 and retracts plate 5, can be arranged on the mobile bar 1 or solid by contiguous block 3 respectively
On the vertical edge of fixed pole 8, different combinations is formed.For example, the hook retractor 7 can be arranged on the vertical edge of the fix bar 8,
The traction plate 5 is arranged in the mobile bar 1, meets the needs of semi-vertebral plate operation.Or in mobile bar 1 and fix bar 8
Vertical edge on be respectively mounted it is described traction plate 5, can meet full state chart operation needs.Meanwhile the hook retractor 7 or traction plate 5 are equal
It can be moved by vertical edge of the contiguous block 3 along the mobile bar 1 or fix bar 8, to obtain different size of surgical field of view.
Spline-simulating neck is respectively equipped with the horizontal edge and vertical edge and the mobile bar 1 of the fix bar 8；The contiguous block
3 be open hollow box-like in both ends, is capable of being socketed in the fix bar 8 or mobile bar 1 of activity；Set on the contiguous block 3
There is spanner 2 with teeth.When pulling the spanner 2, the latch can be driven to rotate and be caught in or depart from the neck, make institute
State contiguous block 3 and the fix bar 8 or the mutually locking of mobile bar 1 or unblock.
The hook retractor 7 is complete two used, is each that bending is shaft-like, and its lower end is provided with crotch, its upper end and
The contiguous block 3 is fixedly linked, and can adjust the distance between two hook retractors 7 by mobile link block 3, and then adjust support
The scope opened.Preferably, the similar more sets of shape can be made in the hook retractor 7, have the difference for meeting compatriots' parameter respectively
Dimensions, so that the drawing of spinous process side when meeting the operation of different building shape patient semi-vertebral plate appears.
The traction plate 5 is circular arc tabular, and its upper end is provided with the connection sheet of triangle.The upper end of the connection sheet passes through company
