Description
Technical field
The present invention relates to medical appliance fields, and in particular to micro-wound percutaneous atlas posterior internal fixation system.
Background technique
Atlas is also known as atlas, for annular, is made of anterior arch, cantle and two lateral mass.Research shows that axial compression is
The main reason for leading to Study of Atlas Fracture by Finite.The parting of Study of Atlas Fracture by Finite is as follows: the damage of I type is that individual anterior arch or cantle are fractured, II type
Damage is that atlas part Front Frame and rear structure damage simultaneously, and III type is lateral mass damage, and no matter whether front and back bow fractures.It is right
In the treatment of Study of Atlas Fracture by Finite, clinically generally fixed using Philadelphia traction, neck brace, way of escape C1-2 is merged, fixed outside head-ring waistcoat
Deng.To the III type fracture of I type, II type fracture and the atlas ring breakage that occur shifting, need fixed outside row head-ring waistcoat；After fixation
It crosses and extends through bit slice in the wrong such as prompt extensive region tooth anterior diastema > 5mm, and the Study of Atlas Fracture by Finite of a small number of first fracture or Unstable internal fixation, need to go
Way of escape C1-2 fusion.For have operation pointer Study of Atlas Fracture by Finite, the present invention can small percutaneous incision complete operation, retain cervical vertebra rotation
Turn, under the premise of stretching and beading function, achievees the purpose that Titanic micro-plates simultaneously, it is minimally invasive to set nail, the destruction of cervical spinal anatomy is reached
To minimum.
In the prior art, there is the Study of Atlas Fracture by Finite of operation pointer generally to use posterior occipitocervical fusion, extensive region pillow fusion, extensive region pivot
The modes such as fusion.Above-mentioned modus operandi is both needed to row cervical vertebra Posterior midline approach, the cervical vertebral bodies such as exposure occipital bone, atlas, dentata.Operation
Notch is larger, and easy damaged veniplex, intraoperative hemorrhage is more, and operating difficulty is big, and risk is high, and easily causes the sense of deep tissue
Dye.Traditional operation is in order to obtain Titanic micro-plates, often to sacrifice cervical vertebra stretching and beading, rotation function as cost, as Occipitocervical fussion, extensive region are rested the head on
Fusion, the fusion of extensive region pivot etc..Patient often loses part cervical vertebra stretching and beading, rotation function while receiving Study of Atlas Fracture by Finite treatment.
Summary of the invention

It is identical；The length of screw can be obtained by the scale on screw tap handle)；Expander is removed after tapping, retains seal wire；Twist nail
Device is screwed into lateral mass screw (ensuring that the direction of screw is consistent with the depth)；The mounting head that U-shaped sets stick device one end is equipped with pitman,
Lateral mass screw is inserted by first through hole, fourth hole and follows closely tail, and perspective after position is ideal, connects needed for U-shaped is set and read on stick device
The length taken over the baton；Extract U-shaped and set stick device, the pitman of appropriate length is installed in the one end Yu Qizhong, by pitman by first through hole,
Fourth hole is inserted into the fixation hole of nail tail of lateral mass screw；After perspective is shown in that position is satisfied, tail cap is temporarily twisted using compression bottle opener；
By being inserted into anti-rotary sleeve in the second through-hole, third through-hole, locked bottle opener, the tail cap of locking screw ailhead, until locking screw are used
Mother is broken off, and the nut to fracture is retained in locked bottle opener；Pull out locked bottle opener and anti-rotary sleeve, exit it is U-shaped set stick device, close
Wound.
Above, it is existing for guiding needle, seal wire, 3 grades of expanders, screw tap, compression bottle opener, locked bottle opener, anti-rotary sleeve
Common surgical medical equipment in technology, stubborn spike devices include the anti-rotary sleeve being connected with lateral mass screw and U-shaped set stick
Device, anti-rotary sleeve are provided with a through-hole parallel with fixation hole far from one end of lateral mass screw, and U-shaped stick device one end of setting is across two
In the fixation hole of lateral mass screw, the other end passes through the through-hole of two anti-rotary sleeves, can guarantee that the direction of two lateral mass screws is complete
Unanimously.
Due to the above technical solutions, the present invention has the following advantages over the prior art:
1, the configuration of the present invention is simple is compact, convenient and reasonable operation, can make to perform the operation it is faster effectively；
2, merging positioning, the merging of pitman that arc frame body of the invention facilitates in operation for Kirschner wire position；
3, reduce open wound when operation fixed the invention enables atlas, only need four miniature incisions, mitigate
The pain of patient, shortens the recovery time in patient's later period, is conducive to the rehabilitation of the state of an illness；
4, the present invention sets nail using the completion of micro-wound percutaneous small notch, under the premise of retaining Cervical Rotating, stretching and beading function, reaches
Purpose to Titanic micro-plates shortens operating time simultaneously, without exposure centrum, reduces the risk of deep tissue infection；Hand
Art notch is small, and intraoperative hemorrhage is less, has clear advantage.
