Through hole 510；
Screwdriver rod 600, is inserted into guide channel 110, and screwdriver rod 600 is provided with the bar portion for being available for guide pin 300 to insert
Axially extending bore 610；One end of screwdriver rod 600 is provided with bar portion internal thread corresponding with interarticular screw 10；Screwdriver rod 600 it is another
One end is provided with and is available for the rotation draw-in groove 630 that the head of binding circulator 700 is inserted；
Interarticular screw 10 is provided with the nail portion axially extending bore 11 for the insertion of guide pin 300；Bullet is additionally provided with access sheath 100
Property keeper 120, the positioning end of flexible positioning piece 120 is stretched into guide channel 110, and the positioning end of flexible positioning piece 120 can be pressed
Tapered sleeve 210 and screw tap 500 in tight insertion guide channel 110.
In the guide channel 110 of the insertion access sheath 100 of passage-opening awl of the invention 200, for being opened in articular process 1
Hole operation；Because passage-opening awl 200 includes tapered sleeve 210 and awl 220, in perforate, awl 220 is inserted in tapered sleeve 210；Opening
Kong Hou, awl 220 takes out from tapered sleeve 210, and tapered sleeve 210 can realize the protection to proximity of muscle tissue.One end of guide pin 300
It is inserted into the hole that awl 220 is opened, the other end of guide pin 300 is inserted into screw tap 500, screwdriver rod 600 and joint
In prominent screw 10, made with playing guiding to the screw tap 500 in insertion access sheath 100, screwdriver rod 600 and interarticular screw 10
With.The head of drill bit 400 is used to drill, and the head of screw tap 500 is used for tapping.One end connection interarticular screw of screwdriver rod 600
10, in the rotation draw-in groove 630 of the other end of the insertion screwdriver rod 600 of binding circulator 700, binding circulator 700 can drive bottle opener
Bar 600 is moved to the direction away from interarticular screw 10, interarticular screw 10 is separated with screwdriver rod 600.
The setting of flexible positioning piece 120 can make the axis of tapered sleeve 210 and screw tap 500 in insertion guide channel 110 with
The axis of guide channel 110 is conllinear.
Apparatus is followed closely in the articular process of the present embodiment, screw way precisely can be effectively accomplished fluently, due to passage-opening awl 200, drill bit
400th, screw tap 500, screwdriver rod 600 are inserted in guide channel 110, so can protect proximity of muscle group during nailing
Knit.
Apparatus is followed closely in articular process also to be included：Bone reamer 900, bone reamer 900 can be inserted into guide channel 110；Bone reamer 900
It is provided with the knife portion axially extending bore 910 for being available for guide pin 300 to insert.Bone reamer 900 can be in the hole in the hole of the tapping of articular process 1
Mouth grind it is corresponding with the structure of the junction of the post 12 and the head of a nail 13 of interarticular screw 10 be recessed, the depression can effectively drop
Incisura after low upper nail.
In the present embodiment, the screw thread in the post 12 of interarticular screw 10 is varying pitch, post 12 away from the head of a nail 13
One end for post 12 front end, post 12 connection the head of a nail 13 one end for post 12 rear end, from the front end of post 12 to
The rear end of post 12, pitch diminishes successively；When such structure makes the post 12 of interarticular screw 10 enter to follow closely, interarticular screw 10
Post 12 the speed in hole that enters in articular process 1 of front end it is fast, the rear end of the post 12 of interarticular screw 10 enters articular process 1
On hole speed it is slow, form a function for pressurization, be more beneficial for interarticular screw 10 and articular process 1 is coupled fusion.
The front end of bone reamer 900 is exactly that bone reamer 900 needs to stretch into the one end in the hole that drill bit 400 is bored, bone reamer 900
Front end include the light bar portion 920 that sets gradually and reamer portion 930, the external diameter of light bar portion 920 is identical with the diameter of drill bit 400,
The internal diameter of light bar portion 920 is identical with the diameter of guide pin 300, can play guide effect；The reamer portion 930 at the rear of light bar portion 920
Shape it is identical with the structure of the junction of the post 12 and the head of a nail 13 of interarticular screw 10, to the hole opened in articular process 1
After aperture carries out scraping hinge treatment, the head of a nail 13 of interarticular screw 10 can be buried to the bone plane of articular process 1, reach zero incisura
Effect.
In order that binding circulator 700 is more stable with the connection of screwdriver rod 600, rotation draw-in groove 630 is ring-like draw-in groove, rotation
The inner ring surface 631 of draw-in groove 630 is hexagon, and it is circle to rotate the outer ring surface 632 of draw-in groove 630；The head of binding circulator 700 sets
There is mounting groove 710, the inwall 711 of mounting groove 710 is the corresponding hexagon of inner ring surface 631 with rotation draw-in groove 630, mounting groove
710 outer wall 712 is corresponding with the outer ring surface 632 of rotation draw-in groove 630 circular.
The outer peripheral face of screwdriver rod 600 is provided with indication wire, and indication wire is black, when indication wire is close to passage barrel end
When, represent that interarticular screw 10 is squeezed into screw way completely, in case doctor's overexertion, protects patient not to be subject to secondary wound
Wound.
Following closely apparatus for the ease of driving screw tap 500 or screwdriver rod 600 to rotate, in articular process also includes：Handle is installed
800, handle 800 is installed and is provided with the handle portion axially extending bore 810 for being available for guide pin 300 to insert；Installing handle 800 can drive drill bit
400th, screw tap 500 or screwdriver rod 600 rotate.
Because the other end of the afterbody, the afterbody of bone reamer 900 and screwdriver rod 600 of screw tap 500 is equipped with jointing 20,
The head for installing handle 800 is provided with the link slot for being available for jointing 20 to insert.Afterbody, bone reamer 900 when screw tap 500
When jointing 20 on the other end of afterbody or screwdriver rod 600 inserts link slot, handle 800 is installed and is achieved that and screw tap
The grafting of the other end of 500 afterbody, the afterbody of bone reamer 900 or screwdriver rod 600.
Flexible positioning piece 120 includes the spring 121 and hoodle 122 that are arranged in access sheath 100 and are connected, hoodle
Stretch into guide channel 110 122 one end away from spring 121.One end away from spring 121 of hoodle 122 is exactly fixed elasticity
The positioning end of position part 120.One end away from spring 121 of hoodle 122 can limit tapered sleeve 210, brill in insertion guide channel 110
First 400 and the shift position of screw tap 500, the structure of spring 121 and hoodle 122 be easy to tapered sleeve 210, drill bit 400 and screw tap 500 from
Taken out in guide channel 110；Flexible positioning piece 120 in the present embodiment is at least two, the edge of at least two flexible positioning piece 120
The circumference for access sheath 100 is uniformly distributed.Hoodle 122 can prop up insertion guide channel 110 in tapered sleeve 210, drill bit 400,
Screw tap 500 and bone reamer 900 simultaneously give its certain pressure, play a part of interim positioning.
Tapered sleeve 210 is provided with dentation convex portion 212.The dentation convex portion 212 of the head of tapered sleeve 210 can be embedded in awl 220 and be opened
Hole arrival end in, with stabilising direction and reaming.
