Description
Technical field
The present invention relates to a kind of medicine equipment, a kind of dicyclic pivot cone cdontoid process sight guiding hollow screw location in fracture of odontoid process of vertebra dentata is treated.
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.The odontoid fracture disunion rate that untreated or malpractice cause is 42-72%, and it is fixed to there is potential atlanto-axial instability simultaneously, the acute or chronic damage of brain stem, spinal cord or nerve root may be caused, cause serious quadriplegia, respiratory dysfunction, even dead.Therefore the patient of fracture of odontoid process of vertebra dentata is answered active treatment.Since reported first in 1981 uses the direct treatment of internal fixation of odontoid fracture of screw, clinical practice has proven to, compared with traditional methods for the treatment of, this technology is possible not only to rebuild the stability of articulatio atlantoepistrophica, can also retain the activity of articulatio atlantoepistrophica to greatest extent, operation wound is little, and union rate is high, and it being obviously improved patients ' life quality, it is believed that this technology is the first-selection of odontoid fracture operative treatment.Although the curative effect of anterior screw treatment of internal fixation of odontoid fracture is affirmed the most clinically, but in the past owing to mainly operating by rule of thumb, guide Kirschner wire to need repeatedly to adjust, operation randomness is big, possibly even produce serious complication, injure spinal cord etc. including screw extraction, displacement fracture, nonunion or screw tapping cdontoid process.Chinese patent 2012102768399 discloses one " axis odontoid screw sight ", it uses nut to regulate two shrinking connecting-rods being arranged on hollow guiding pipe thus changes the sensing of hollow guiding pipe, two shrinking connecting-rods are connected on vernier control plate, and vernier control plate is connected with support bar by ball-joint.This axis odontoid screw sight may be used for guiding Kirschner wire to be accurately positioned in fracture of odontoid process of vertebra dentata treatment, thus improves surgical quality, reduces surgical error, reduces the misery of patient.But in surgical procedure, owing to the position needing regulation is numerous, and it is interrelated to regulate each point of adjustment, generally requires adjustment repeatedly and can be only achieved requirement, affects operation progress.It addition, the length of the shrinking connecting-rod of nut regulation is difficult to precisely measure, the position that shrinking connecting-rod is connected on vernier control plate is the most uncertain, and this axis odontoid screw sight can not use coordinate data record position, it is impossible to the location in operation before repetition.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, easy to use, governing speed fast, the dicyclic pivot cone cdontoid process sight of available coordinate representation position, Kirschner wire is guided to be accurately positioned in fracture of odontoid process of vertebra dentata is treated, thus improve surgical quality, reduce surgical error, reduce the misery of patient.
The present invention solves that technical problem be the technical scheme is that
Dicyclic pivot of the present invention cone cdontoid process sight includes hollow guiding pipe and is connected to the sighting device on hollow guiding pipe, described sighting device includes inner sleeve and the outer sleeve being arranged concentrically, the external diameter of described inner sleeve is less than the internal diameter of outer sleeve, the external diameter of described hollow guiding pipe is less than the internal diameter of inner sleeve, being symmetrically arranged with left half axle and right axle shaft between outer wall and the inner ring surface of inner sleeve of hollow guiding pipe, described left half axle and right axle shaft are coaxially disposed and the axis of left half axle and the right axle shaft center of circle by inner sleeve；It is provided with semiaxis and lower semiaxis, described upper semiaxis and lower semiaxis between outer ring surface and the inner ring surface of outer sleeve of described inner sleeve to be coaxially disposed and the axis of upper semiaxis and the lower semiaxis center of circle by inner sleeve；Upper semiaxis is vertical with the axis of left half axle and right axle shaft with the axis of lower semiaxis；Described upper semiaxis, lower semiaxis, left half axle and right axle shaft are set with by the inner sleeve that can rotate against and be coaxially disposed and outer tube and form.
Described inner sleeve is the annular hollow pipe being connected air pump by high-pressure air pipe, one end of described inner sleeve is fixedly connected on inner sleeve and connects with the tube chamber of inner sleeve, the other end of inner sleeve is provided with air bag, the expanding end of described air bag is positioned in the inner chamber of outer tube, one end of described outer tube connects inner sleeve by rotatable snap ring, and the other end of outer tube is fixedly connected on hollow guiding pipe or outer sleeve.
Described inner sleeve represents the scale of relative position with being provided with on the outer tube wall of outer tube joining place.
After using technique scheme, this sight is by the sensing of dicyclic sighting device regulation guide pipe, simple in construction, easy to use, governing speed soon and available coordinate representation position, the convenient details quantitatively recording operation technique, utilize the repeatable location reproduced in operation of coordinate；Hollow guide device is used to make location Kirschner wire be predominantly located in guider, it is simple to control direction, it is to avoid it bends and causes the suitable illusion of inserting needle；Using air pressure to control swelling gasbag fixation hollow guider, location action is fast, and fixing reliable, after being accurately positioned and positioning, position is fixed, and decreases inserting needle repeatedly, improves the accuracy that screw enters；Need not implant fixing nail on Cervical vertebra and fixing connecting rod is firmly secured to operation table, fixing reliable.
