Technical field
The present invention relates to a kind of medical instrument, guided in specifically a kind for the treatment of for fracture of odontoid process of vertebra dentata hollow
Dentoid process of axis's sighting device of screw positioning.
Background technology
Fracture of odontoid process of vertebra dentata is the common fracture of cervical vertebra, accounts for the 10%~14% of fracture of cervical spine.Untreated or treatment are not
The odontoid fracture disunion rate caused by is 42-72%, and it is fixed to exist simultaneously potential atlanto-axial instability, may cause brain stem,
The acute or chronic damage of spinal cord or nerve root causes serious quadriplegia, respiratory dysfunction, or even dead.Therefore to pivot
The patient of vertebra odontoid fracture answers active treatment.From 1981, report used the direct treatment of internal fixation of odontoid fracture of screw for the first time
Since, it has proven convenient that compared with traditional therapy, this technology can not only rebuild the stability of articulatio atlantoepistrophica for clinical practice,
The activity of articulatio atlantoepistrophica can also be retained to the maximum extent, operation wound is small, and union rate is high, and is obviously improved minimal invasive treatment
Quality, it is believed that the technology is the first choice of odontoid fracture operative treatment.Although anterior screw treatment of internal fixation of odontoid fracture
Curative effect is clinically affirmed, but is oriented to Kirschner wire due to mainly operating by rule of thumb in the past and is needed to adjust repeatedly, and performed the operation
Randomness is big, in some instances it may even be possible to generate serious complication, including screw extraction, displacement fracture, nonunion or screw tapping
Cdontoid process and injure spinal cord etc..Chinese patent 2012102768399 discloses one kind《Dentoid process of axis's screw sighting device》, adopt
Two shrinking connecting-rods on hollow guiding pipe are mounted on to change the direction of hollow guiding pipe, two shrinking connecting-rods with nut adjustment
It is connected on vernier control plate, vernier control plate is connect by ball-joint with supporting rod.This dentoid process of axis's screw sighting device
It can be used for guiding Kirschner wire in fracture of odontoid process of vertebra dentata treatment to be accurately positioned, to improve surgical quality, reduce surgical error,
Reduce the pain of patient.But it in the course of surgery, since the position for needing to adjust is numerous, and adjusts each point of adjustment and mutually closes
Connection, generally requires to adjust repeatedly and can be only achieved requirement, influences operation progress.In addition, the length of the shrinking connecting-rod of nut adjustment is difficult
Precisely to measure, the position that shrinking connecting-rod is connected on vernier control plate is not known yet, this dentoid process of axis's screw sighting device
Coordinate data record position cannot be used, the positioning in can not performing the operation before repetition.
Invention content
The object of the present invention is to provide a kind of simple in structure, easy to use, governing speeds soon, can use coordinate representation position
Dentoid process of axis's sighting device, guiding Kirschner wire is accurately positioned in being treated for fracture of odontoid process of vertebra dentata, to improve operation matter
Amount reduces surgical error, reduces the pain of patient.
The present invention is for technical scheme applied to solve the technical problem：
Dentoid process of axis's sighting device of the present invention includes hollow guiding pipe and is connected on hollow guiding pipe
Sighting device, the sighting device include the inner sleeve and outer sleeve being arranged concentrically, and the outer diameter of the inner sleeve is less than outer sleeve
Internal diameter, the outer diameter of the hollow guiding pipe is less than the internal diameter of inner sleeve, the outer wall of hollow guiding pipe and the inner ring surface of inner sleeve
Between be symmetrically arranged with left half axle and right axle shaft, the left half axle and the axis of right axle shaft coaxial arrangement and left half axle and right axle shaft
The center of circle that line passes through inner sleeve；It is provided with semiaxis and lower half between the outer ring surface of the inner sleeve and the inner ring surface of outer sleeve
The center of circle that axis, the upper semiaxis and the coaxial arrangement of lower semiaxis and the axis of upper semiaxis and lower semiaxis pass through inner sleeve；Upper semiaxis
It is vertical with the axis of left half axle and right axle shaft with the axis of lower semiaxis；The upper semiaxis, lower semiaxis, left half axle and right axle shaft by
Can the inner sleeve and outer tube of relative rotation and coaxial arrangement be set with；Connecting plate and connecting seat are set on the outer sleeve.
The scale for indicating relative position is provided on the outer tube wall of the inner sleeve and outer tube joining place.
The inner sleeve is the annular hollow pipe that air pump is connected by high-pressure air pipe, and one end of the inner sleeve is fixedly connected
It is connected on inner sleeve and with the tube chamber of inner sleeve, the other end of inner sleeve is equipped with air bag, and the expanding end of the air bag is located at
In the inner cavity of outer tube, one end of the outer tube connects inner sleeve, the other end of outer tube by rotatable snap ring
It is fixedly connected on hollow guiding pipe or outer sleeve.
After adopting the above technical scheme, the sighting device adjusts the direction of guide pipe, structure letter by dicyclic sighting device
Single, easy to use, governing speed is fast and available coordinate representation position, the convenient details for quantitatively recording surgical procedure utilize coordinate
The repeatable positioning reproduced in operation；Positioning Kirschner wire is set to be predominantly located in guider using hollow guide device, convenient for control
Direction avoids it from being bent and cause the suitable illusion of inserting needle；Using pressure control swelling gasbag fixation hollow guider, positioning is dynamic
Make soon, fixed reliable, position is fixed after accurate positionin and positioning, reduces inserting needle repeatedly, improves the accuracy that screw enters；
It need not be implanted into fixing glue on Cervical vertebra and fixed connecting rod is firmly secured to operating bed, it is fixed reliable.
