Abstract

A spine fixator with adjustable angle is composed of a supporting part, a top seat, a bottom seat and two angle regulating mechanisms linked between said supporting part and top (and bottom) seat and with length regulating function. It features that the angles of top and bottom seats can be regulated for matching with the angles of lower and top end plates for upper and lower spine bones.

Description

Vertebra fixer

Technical field

The present invention is relevant a kind of vertebra fixer, the particularly vertebra fixer of relevant a kind of adjustable angle.

Background technology

Tradition vertebra fixer (for example referring to Fig. 1) can't be adjusted angle, can not be suitable for to be the vertebra fixer between different vertebral segments, if use reluctantly, treats that with making the relative position of fixed vertebral segments after fixing changes, and causes spinal fixation improperly.

Summary of the invention

One of purpose of the present invention is to provide a kind of vertebra fixer of adjustable angle.

Another object of the present invention is to provide a kind of vertebra fixer with angle-adjusting mechanism.

Another purpose of the present invention is to provide a kind of vertebra fixer with angle-adjusting mechanism and height adjustment mechanism.

Vertebra fixer of the present invention, it comprises:

One support component;

One footstock, it is and this support component top combination;

One base, it is and this support component bottom combination;

It is characterized in that: the combination of the combination of this footstock and support component and/or this base and support component is with the angle-adjusting mechanism combination, make this footstock and or this base can adjust angle between itself and this support component according to need.

The footstock of stating, its shape and structure there is no specific limited, and for example it can be the holder (referring to the holder shown in Fig. 1-a label 10 and 20) of traditional vertebra fixer, or similar structure (referring to the footstock shown in Fig. 2 label 300).

Above-mentioned base, its shape and structure there is no specific limited, and for example it can be the holder (referring to the holder shown in Fig. 1-a label 10 and 20) of traditional vertebra fixer, or similar structure (referring to the base shown in Fig. 2 label 200).

Above-mentioned support component, its shape there is no certain limitation, for example the support component (referring to the support component shown in Fig. 1-a label 40) that it can roughly the same traditional vertebra fixer.Unique the junction with footstock or base has the part or all of of angle-adjusting mechanism.

Above-mentioned angle-adjusting mechanism, it can be to have arbitrarily adjusts angle view of function guiding mechanism (for example gear type angle-adjusting mechanism), screws togather the formula angle-adjusting mechanism or similar structures is preferable with curved surface shown in Figure 2.

The combination of above-mentioned support component and footstock, and the combination of support component and base, at least a is to adopt angle-adjusting mechanism, it is preferable all adopting angle-adjusting mechanism with two kinds.When the combination of support component and footstock (or support component and base) was not adopted angle-adjusting mechanism, then this footstock (or base) was preferable to form one (being integrally formed referring to Fig. 1-a

label

10 and 40 for example) with this support component.When angle-adjusting mechanism is adopted in the combination of this support component and footstock (or support component and base), this angle-adjusting mechanism all is positioned on this support component or the footstock (or base), or part is positioned at support component, partly on footstock (or base), or partly be positioned at support component, partly on footstock (or base), partly use so that this support component and footstock (or base) combination closely, with the latter two is preferable, is the best with last described person.

Above-mentioned support component, in case of necessity, can have a height adjustment mechanism, this height adjustment mechanism can adopt arbitrarily common height adjustment mechanism (for example referring to Fig. 1-a), but with height adjustment disclosed in this invention mechanism (referring to Fig. 2 and Fig. 6-a, is preferable 6-b).

The present invention utilizes angle-adjusting mechanism, make footstock and/or base can adjust angle between itself and support component according to need, the angle that footstock and base are constituted, and treat that angle is identical between the last soleplate of the fixing following soleplate (end-plate) of going up vertebral segments and following vertebral segments.

Angle-adjusting mechanism of the present invention, its support component also can have height adjustment mechanism, makes it have the effect of adjusting height and adjusting angle simultaneously.
