Abstract
The utility model provides an anterior locking cervical plate system which belongs to clinical medicine spinal surgery cervical unofficial decision instrument which is suitable for curing diseases such as lumbar intervertebral disc protrusion and wound. The anterior locking cervical plate system includes a cervical plate and a bone screw, the cervical plate is equipped with two rows of bone screws, the bone screw is assembled in the bone screw hole, an elastic ring seat is set between two rows of bone screws in the cervical plate middle part, an elastic ring is set in the elastic ring seat, the elastic ring flicks the bone screw closing and tightening two sides. The anterior locking cervical plate system has simple structure and reliable self-lock, is not easy to deform and is convenient for clinical operation, can uses the bone screw with fixed angle according with various patient condition and also can use the screw with adjustable angle.
Description
Technical field
This utility model anterior plate fixation fixed system belongs to clinical medicine spinal surgery cervical vertebra operating theater instruments decided at the higher level but not officially announced, is applicable to diseases such as treatment prolapse of lumbar intervertebral disc, wound.
Background technology
Anterior plate fixation internal fixation technology treatment prolapse of lumbar intervertebral disc, wound, tumor etc. have been widely used in clinical.Because human spine's special physiological structure and movable frequent, very high to the design and the requirements of weaving process of anterior plate fixation, not only volume is little, the fatigue resistance height, and must guarantee tight security.Particularly the bone screw that uses in this system causes the internal fixation failure if no locking device causes the loosening of screw easily and withdraws from steel plate.Gently then cause the patient to perform the operation once more, heavy then can pierce through organ crisis life.The like product of present clinical use though locking device is all arranged, all is to be screwed into other screw again or to lock with method such as tiltedly taking along after the synthetism spiral shell is fixing, be secondary locking, trouble not only, and lock unreliable, have potential safety hazard, locking device is short service life.
The utility model content
The technical problems to be solved in the utility model is: unreliable for the locking of existing anterior plate system, as to have potential safety hazard etc. problem, this utility model provides a kind of anterior plate fixation fixed system, it adopts the self-locking of bullet circle, the bullet circle automatically springed open and holds out against bone screw after bone screw was screwed into, and self-locking is reliable.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of anterior plate fixation fixed system, have cervical steel plate, bone screw, cervical steel plate is provided with two row bone screw hole, bone screw is assemblied in the bone screw hole, two row connect and are provided with the bullet ring support between the screw in the middle of the cervical steel plate, play in the ring support bullet circle is installed, the bullet circle automatically springs open the bone screw that holds out against both sides.
Described bone screw has fixed angle bone screw and angle adjustable bone screw, and the boss of fixed angle bone screw lower head is outer through cooperating with the bone screw aperture, and the boss of angle adjustable screw head below is outer through being slightly smaller than the bone screw aperture.
Be provided with the perspective window between the adjacent two bullet circles in the middle of the described steel plate, be convenient to the situation that the doctor observes patient.
Described bone screw disposes special-purpose release bottle opener.
The beneficial effects of the utility model are: this anterior plate fixation fixed system is simple in structure, and self-locking is reliable, and the bullet circle is difficult for deformation failure, and clinical manipulation is very convenient, can adopt the fixed angle bone screw, also available angle adjustable screw according to patient's different situations.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is an assembling sketch map of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structural representation of cervical steel plate.
Fig. 4 is the structural representation of release bottle opener.
Among the figure: 1. cervical steel plate, 2. bone screw, 21. fixed angle screw, 22. angle adjustable screws, 3. bone screw hole 4. plays ring support, 5 bullet circles, 6. perspective window, 7. release bottle opener.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of anterior plate fixation fixed system, have cervical steel plate 1, bone screw 2, cervical steel plate 1 is provided with two row bone screw hole 3, bone screw 2 is assemblied in the bone screw hole 3, be provided with between the two row bone screws 2 in the middle of the cervical steel plate 1 and play ring support 4, play in the ring support 4 bullet circle 5 is installed, bullet circle 5 automatically springs open the bone screw 2 that holds out against both sides.
Cervical steel plate 1 is according to clinical instructions for use, and the steel plate length design has plurality of specifications, bone screw hole 3 that 4 holes, 6 holes, 8 holes also should be arranged mutually, places bone screws 2 in the bone screw hole 3.
Bone screw 2 screws in vertebral body in the bone screw hole 3 of cervical steel plate 1, cervical steel plate 1 is fixed on the suitable spinal vertebral, the boss for the treatment of bone screw 2 lower head sticks in the bone screw hole 3, and cervical steel plate 1 intermediary bullet circle 5 automatically springs open, and holds out against bone screw 2.Different situations according to patient can be used fixed angle screw 21, also can use angle adjustable screw 22.In operation process, after bone screw 2 is screwed in the vertebral body, to find improperly, the release bottle opener 7 of available dedicated takes out bone screw, as shown in Figure 4, ressembles bone screw 2.
