Abstract
The invention discloses an odontoid process guidepin aiming device, which is provided with a connecting beam of which one end is inserted with a hollow guide drill used for sleeving a guidepin; the connecting beam at the end part is provided with a hollow guide drill locking device; the middle of the connecting beam is provided with a universal adjuster capable of being locked on the connecting beam; and an adjustable fixing post is inserted into the universal adjuster. The odontoid process guidepin aiming device can make axial leads of the hollow guide drill and an odontoid process in the same line, accurately determine angles and positions of the hollow guide drill and the guidepin, has accurate feed direction, is difficult to generate deviation, effectively solve the problems of shift of fastening screws and poor healing or deformed healing of odontoid process fracture, avoids puncturing dura mater spinalis and nerves, can drive in the guidepin for one time according to surgical requirements, shortens the time of a surgery, and reduces surgical wounds and complicating diseases.
Description
Technical field
The invention belongs to the Orthopeadic Surgery technical field of medical instruments, be specifically related to a kind of odontoid process guidepin aiming device.
Background technology
Through the existing 20 years history of the prominent fracture of throat road tooth hollow screw fixation, be mainly used in the prominent fracture of the shallow III type of Anderson II type and Anderson tooth, operation acquires a certain degree of difficulty, and can cause the internal fixation screw skew, the tooth not good or malunion of union of fracture of dashing forward, even stab spinal dura mater and nerve.During the prominent fracture of the tooth of being expert at multiple screws, the first step will penetrate guide pin, because of pin is thin, and distance, the inserting needle direction is difficult for grasping, and is prone to deviation.As to proofread and correct, inserting needle again, often be difficult to avoid former needle track, thereby cause internal fixation position and poor effect.
Summary of the invention
The technical problem to be solved in the present invention is to be prone to deviation for overcoming existing guide needle on the inserting needle direction, and a kind of odontoid process guidepin aiming device is provided, and to shorten operating time, reduces operation wound and complication.
For solving the problems of the technologies described above, the present invention has the connection crossbeam, and an end that connects crossbeam is fitted with the hollow guide bur that is used for the suit guide pin, and the connection crossbeam of this end is provided with hollow guide bur locking device; Be provided with the universal adjustment device that may be locked on the connection crossbeam at the middle part that connects crossbeam, be fitted with adjustable fixed bar in the universal adjustment device.
Described connection crossbeam is a screw rod, and described universal adjustment device is locked on the connection crossbeam by the nut at its two ends.
Be provided with the locking tooth that is used for fixed angle between described universal adjustment device one end and the nut.
Described universal adjustment device is the mutual spiral-lock in outer end two lamellar bodies together, and these two lamellar body the inners are sleeved on the described connection crossbeam, are provided with the groove that grips bar between two lamellar bodies.
Described locking device is to be installed in the lock screw that connects beam-end.
During use, conventional otch, appear the vertebral body anterior diastema, by the perspective location, determine C2, the C3 intervertebral space, lower edge point before the excision C2 vertebral body supports lower edge before the C2 vertebral body with the hollow guide bur that is inserted in guide pin, the range estimation aiming, direction according to extended line is fixed to C4 or C5 vertebral body with fixed bar, and the distance of adjusting hollow guide bur angle and hollow guide bur and fixed bar by the universal adjustment device on the connection crossbeam is also fixing, and positive side position perspective guarantees that the extended line of hollow guide bur or guide pin is positioned at tooth and dashes forward central, squeeze into guide pin, perspective is examined its position again, be of convenient length, squeeze into, withdraw from hollow guide bur, the dismounting sight, be screwed into hollow screw, operation is finished in the perspective back.
From the above mentioned, the present invention is owing to be fitted with the hollow guide bur that is used for the suit guide pin at an end that connects crossbeam, and the connection crossbeam of this end is provided with hollow guide bur locking device; Be provided with the universal adjustment device that may be locked on the connection crossbeam at the middle part that connects crossbeam, be fitted with adjustable fixed bar in the universal adjustment device, can make hollow guide bur and the tooth axial line conllinear of dashing forward, determine angle, the position of hollow guide bur and guide pin accurately, the inserting needle direction is accurate, be not prone to deviation, effectively solve the hold-down screw skew, the tooth not good or malunion of union of fracture of dashing forward, avoid stabbing spinal dura mater and nerve, can shorten operating time by the disposable guide pin of squeezing into of requirements of operation, reduce operation wound and complication.
