All other embodiment obtained, fall within the protection scope of the utility model.
Refering to fig. 1 shown in -8, a kind of preceding road hollow screw operation auxiliary Path Setup device of upper cervical spine, including access sheath
1 and sting device 2, access sheath 1 include the service aisle pipe 11 of the inner hollow being inserted in step by step, first order expanded casing 12,
Second level expanded casing 13, third pole expanded casing 14 and quadrupole expanded casing 15, the top side of service aisle pipe 11 are set
There is hand-held part 111, the outer diameter of service aisle pipe 11 is 1cm, internal diameter 0.8cm, length 10.5cm, and service aisle pipe 11 is worn
Piercing inclination angle of inclined plane is 25 °, and the outer diameter of first order expanded casing 12 is 0.8cm and is decremented to fourth stage expansion with the differential of 0.2cm
Casing 15, sting device 2 include hollow puncture needle 21 and needle core 22, hollow puncture needle 21 and 22 nested encryptions of needle core, band trepan
Puncturing lever 3 include hollow loop bar 31 and trepan puncturing lever 32, trepan puncturing lever 32 passed through from the cavity of hollow loop bar 31 and with
Hollow loop bar 31 is threadedly coupled, and hollow screw tap 4 is made of handle 41 and screw tap bar 42, and the front end of screw tap bar 42 is equipped with tapping spiral shell
Line, guiding device 5 include hollow boring bit 51 and guide pin 52, and 51 front end of hollow boring bit, which is equipped with, pierces screw thread, and guide pin 52 passes through hollow
The cavity of drill bit 51 is connect with 51 fitting of hollow boring bit, and the guide pin 52 of the guiding device can be with the hollow puncture of sting device
Needle 21, the fourth stage expanded casing 15 of access sheath, band trepan puncturing lever 3,4 nested encryptions of hollow screw tap.
Specific use process is as follows for the present apparatus: the first step, has an X-rayed the lower reduction of the fracture.In thyroid cartilage right border longitudinal incision
0.5 centimetre of skin incision, index finger presses on notch upper and lower respectively in left hand, and vagina vasorum and esophageal intubation are pushed away and separated simultaneously by finger tip
It is promoted toward cervical vertebra.It passes through deep fascia through skin incision using sting device 2 and swings up and down and reach cervical vertebra anterior median line, C
Arm lateral view is examined determine that it is located at centrum forward position after, swing and separate cervical vertebra/esophagus gap and be sent under dentata centrum upwards
1/3, it is retracted into dentata centrum lower edge, the adjustment of positive side position observes hollow puncture needle 21 and is located at cdontoid process axis, takes out needle core 22, thoroughly
Guide pin 52, which is pierced, through hollow puncture needle 21 depending under and adjusts guide pin 52 enters dentata lower lip position, angle direction and be sent to cdontoid process
Tip.Retain guide pin 52, extracts hollow puncture needle 21.
Step 2: expanded casing is expanded deep fascia and deep gap along guide pin 52 and is organized step by step, namely from minimum outer diameter
Fourth stage expanded casing 15 is gradually pierced into first order expanded casing 12, since the outer diameter of fourth stage expanded casing 15 increases step by step
To first order expanded casing 12, during expanding step by step can more docile, prevent the channel of expansion from deviation problem occur；So
