Description
Technical field
This utility model relates to a kind of Orthopedic Clinical apparatus, particularly relates to a kind of anterior approach slope fixture.
Background technology
For row Reconstruction after the large portion excision of neck 1,2 vertebral tumor, performed the operation in the past and all adopt the direct screw of anterior approach abnormity titanium net to fix, or use bones of limbs steel plate to be fixed.But these methods enough do not stablize lasting fixed effect, therefore, the method utilizing slope to carry out anterior cervical vertebrae titanium net or titanium plate internal fixtion is considered to have better stability.At present existing special through anterior approach slope to the steel plate apparatus that neck 3 vertebral body is fixing, but the application of the type steel plate depends on the complete of lateral mass of atlas anatomical structure, is therefore necessary to develop new anterior approach slope steel plate, to reaching better stablizing effect.
Summary of the invention
The purpose of this utility model is the anterior approach slope fixture providing a kind of improvement, and it is exclusively used in the fixture fixing to neck 3 vertebral body through anterior approach slope, can reach the fixed effect more more reliable and more stable than other anterior approach fixtures existing.
The anterior approach slope fixture of improvement described in the utility model comprises the slope fixed part of upper end and the vertebral body fixed part of lower end; Described slope fixed part is provided with three locking screws, and triangularity arranges, so that by screw, described slope fixed part is fixed on anterior approach slope; The centre of described vertebral body fixed part is provided with paired locking screw, so that it is online by screw, described vertebral body fixed part to be fixed on titanium; The bottom of described vertebral body fixed part is provided with paired screw, so that by screw, described vertebral body fixed part is fixed on neck 3 vertebral body.
According to the further feature of anterior approach slope described in the utility model fixture, between described slope fixed part and described vertebral body fixed part, shape has a certain degree.
According to the further feature of anterior approach slope described in the utility model fixture, the angle between described slope fixed part and described vertebral body fixed part is 114 ° to 148 °.
Anterior approach slope described in the utility model fixture, be special through anterior approach slope to the fixture that neck 3 vertebral body is fixing, the Interal fixation mode more in the past used, device of the present utility model is more suitable for the situation of atlas and axis complete resection, and locking hole can the better stability must rebuilding upper cervical spine, the advantageously rehabilitation of patient Yu.

Detailed description of the invention
Embodiment one: the preparation of anterior approach slope described in the utility model fixture
Anterior approach slope described in the utility model fixture, as depicted in figs. 1 and 2, comprises the slope fixed part 8 of upper end and the vertebral body fixed part 9 of lower end; Described slope fixed part 8 is provided with three locking screws 1,2 and 3, and triangularity arranges, so that by screw, described slope fixed part 8 is fixed on anterior approach slope; The centre of described vertebral body fixed part 9 is provided with paired locking screw 4 and 5, so that it is online by screw, described vertebral body fixed part 9 to be fixed on titanium; The bottom of described vertebral body fixed part 9 is provided with paired screw 6 and 7, so that by screw, described vertebral body fixed part is fixed on neck 3 vertebral body.Preferably, the angle between slope fixed part 8 and vertebral body fixed part 9 is 114 ° to 148 °.
Anterior approach slope described in the utility model fixture, can make with steel plate or similar material.
The concrete size of anterior approach slope described in the utility model fixture is individual variation because of different patient and specific design.In a preferred embodiment, anterior approach slope described in the utility model fixture is prepared according to following size.
It is 15mm that minister is fixed on mainboard slope, and the widest part is 20mm, arranges three screws, and triangularity arranges, and is fixed on slope by screw 1,2,3.The wide 15mm of mainboard vertebral body fixed part.Is arranged in the middle of mainboard vertebral body fixed part locking screw, the wide 5mm of screw, on the fixing plant bone mass of screw 4,5 or titanium cage, by rear titanium cage and slope fixture, by locking screw, to carry out entirety fixing.Mainboard vertebral body fixed part lower end is arranged to screw, and screw 6,7 is fixed on neck 3 vertebral body.Mainboard slope fixed part and mainboard vertebral body fixed part have a certain degree, and angular range is 114 ° to 148 °.Fixture thickness is 1.6mm.Screw diameter is 3.5 mm.
Embodiment two: the application of anterior approach slope described in the utility model fixture
It is below embodiment anterior approach slope of the present invention fixture being used for clinical practice.
As shown in Figure 3, the patient lies supine of upper cervical spine pathological changes is on operation table, and through anaesthetizing successfully, the wild skin of sterilization operation on neck, spreads aseptic towel, list.
Get upper cervical spine throat pharynx posterior approach, expose body of cervical vertebra, Fluoroscopy location, excision C1 anterior arch and C2 vertebral body, row C2-3 diskectomy, select suitable titanium cage (Johson & Johnson) to mould head end firmly can be fitted in slope edge, tail end is fixed on C3 soleplate.Fill broken bone block in it, the outwardly extending lip of this titanium cage is stayed front and is fixed to slope and C3 vertebral body to allow screw.After the length of measuring bolt, the os integumentale screw of 4 3.5 mm dias is inserted and is fixed by titanium cage.Rear portion is aided with pillow neck fixture, extends downward the lateral mass of C4.The entrance of slope screw and neck 3 vertebral body screw is measured.Kirschner wire (diameter is 1.0mm) is used to bore a hole at predetermined entry point.Get out screw thread with the drill bit of diameter 2.5 millimeters, then use the reaming of diameter 3.5 millimeters of hand-power screwdrivers.After measuring the length of screw, mainboard slope fixed part three screws 1,2 and 3, triangularity arranges, and is fixed on slope by screw.Be arranged in the middle of mainboard vertebral body fixed part, to locking screw 4 and 5, be fixed on titanium cage by screw, by rear titanium cage and slope fixture, by locking screw, to carry out entirety fixing.Mainboard vertebral body fixed part lower end is arranged to, to screw 6 and 7, be fixed on neck 3 vertebral body by screw.
C arm confirms that internal fixtion is in place, after repeatedly rinsing otch, looks into without active hemorrhage, in cervical incision built-in silica gel tube half Tube Drain one after cervical vertebra sequence is good with normal saline.Sew up subcutaneous tissue and subcutaneous.
