Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of cervical vertebral level angle unobstructed operation probe.
Background technology
Odontoid fracture is a kind of common injury, accounts for the 8%-15% of fracture of cervical vertebra.Odontoid fracture is divided into 3 types, and wherein II type nonunion rate is 15%-85%.Odontoid fracture fixed by clinical employing anterior approach single piece of hollow screw, remains atlas and axis mobility, improves union of fracture rate, and do not need strong extenal fixation after internal fixation treatment, is a kind of Therapeutic Method preferably.
C2 odontoid fracture, front road cannulated compression screw fixation, need first to insert guide pin, the method inserting guide pin is at present: first carry Kirschner wire lower edge before C2 vertebral body with bone drill and pierce boring, after insert guide pin, this Kirschner wire, due to linearly shape, is shown in accompanying drawing 1, there is following substantive deficiency in operation process:
1.C2 position is comparatively dark, and the straight line degree of depth of distance skin is larger.Sometimes in order to obtain good level angle, need to appear from C5.6 level, large to prevertebral fascia damage range, adhesion, the cicatrix scope of formation are large.
2. the two ends of odontoid fracture are level substantially, and inserting Kirschner wire needs to keep close to horizontal level.And otch be positioned at entry point before, downside, there is angle in sagittal plain when entering Kirschner wire, the position of level of approximation can not be kept, cause inserting Kirschner wire difficulty, needing repeatedly, repeatedly changes its course inserts Kirschner wire, causes nail road to expand, makes screw lose due internal validity.
The stop of dead ahead due to mandibular bone of 3.C2 and the existence of the important body of gland of cervical region, directly can not form operative approach, at the horizontal approach of C5, can only need upwards have individual angle.And upwards after angulation, Kirschner wire can not be entered in level of approximation position, cause inserting screw failure, operative failure.
4. because Kirschner wire can not bend substantially, need linear operating, may cause during operation fracture site can not being fixed, Kirschner wire also may be caused to be strayed into intraspinal tube and cause spinal cord injury, simultaneously because the operation of straight line stops operating field, cause damage.
Summary of the invention
