Correspondingly, sliding slot 52 is opened in the cooperation plane of auxiliary functor 2.It is of course also possible to another way is configured, sliding rail 51
It is fixed on the cooperation plane of auxiliary functor 2, correspondingly, sliding slot 52 is opened in the cooperation plane of function of tonic chord part 11.
Furthermore the sliding rail of the 51 " T-shaped " shape of preferred cross-sections shape of sliding rail, so that auxiliary functor 2 and function of tonic chord part 11
Cooperation it is even closer, both guarantee the stationarity of opposite sliding.Lubrication portion can also be set between sliding rail 51 and sliding slot 52
53, preferred embodiment is as follows: it is spaced in the side wall and bottom wall of sliding rail 51 and is inlaid with graphite, and graphite is slightly above plane, with 0.5~
1mm is advisable.In this way, the coefficient of friction of auxiliary functor 2 and function of tonic chord part 11 is just reduced, so that sliding is more smooth, and
Abrasion loss is reduced, guarantees the cooperation precision of the two.The cross sectional shape of sliding rail 51, can be in addition to that can be above-mentioned " T shape " shape
For " dovetail " shape, it is of course also possible to use other any suitable shapes.
Furthermore conventional intervertebral foramen decompression pincers (are cut flat with platform 111 corresponding to stinging in the utility model and sting cutting blade due to jaw
211) height is lower, and itself is higher with the status requirement in minimally invasive duct, it is possible that function of tonic chord part under extreme case
It can just be stung under axis trimming plumbness and switch to bone.In order to solve the above-mentioned technical problem, stinging cut piece 21 can obliquely set
It sets, 35~45 ° of tilt angle, and it is stung cutting blade 211 and be higher by auxiliary functor 2 and is advisable with 4~8mm, and the axis of function of tonic chord part is conducive to
Line tilts 25~50 ° relative to service aisle and is placed, so that the contraposition process for stinging bone early period is more convenient, quick.
Furthermore in order to expand the scope of application of gun-type intervertebral foramen decompression pincers, it is abnormal to be conducive to processing hyperplastic tissue's hypertrophy etc.
Case, can increase to sting cut piece 21 and sting and cut flat with stinging between platform 111 and cut stroke, preferably not less than 18mm.
Furthermore elastic portion 6 can be configured using following manner: the first elastic slice 61 passes through rivet and 12 phase of fixed handle
Fixed, the second elastic slice 62 is fixed also through rivet and 3 phase of flexible handle.Notch, In are offered in the free end of the first elastic slice 61
The free end of second elastic slice 62 is provided with extension body, and the extension body wear in notch, when being held, put to flexible handle 3
When operation, which makees free to slide.As advanced optimizing, above-mentioned first elastic slice 61 and the second elastic slice 62 can be by bullets
Spring steel obtains.
Furthermore in order to improve non-skid property, can also be all provided in the portion of the handle on fixed handle 12 and flexible handle 3
It is equipped with skid resistance strip 7, to improve its handling, raising operation precision.
Furthermore for different situations suitable for performing the operation, the above-mentioned width for stinging cutting blade may be configured as it is a series of, such as:
4mm、6mm、8mm、10mm。
Furthermore one layer of PVD plated film can also be respectively provided on vice body main body 1, auxiliary functor 2, so that stinging cutting blade 211
It is more wear-resisting, sharp, it is not easy to break.In addition, being easy to clean gun-type intervertebral foramen decompression pincers, and will not in use process
There is phenomena such as fading, corrosion.
Finally, Fig. 5 shows the structural schematic diagram under the utility model gun-type intervertebral foramen decompression pincers working condition.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
