Description
Technical field
The present invention relates to medical appliance fields, strut fixator in particular to a kind of posterior cervical self-locking.
Background technique
The current clinical application of cervical posterior approach has 3 kinds of art formulas.The first be canalis spinalis Enlarging decompression art, i.e., after hit exactly into
Road exposure cervical vertebra plate and the vertebral plate for cutting off neck 3 to neck 7；Second is canalis spinalis expansion single open-door decompression, and side vertebral plate is cut entirely
Disconnected opposite side vertebral plate cuts off outer cortex；The third expands double door decompression, cutting among vertebral plate for canalis spinalis, and bilateral lamina is closely closed
The prominent place's excision lateral cortex of section.Three of the above art formula all can be different degrees of destruction neck after muscle spinous process ligament complex, cause
Sagittal alignment, the long-term pain of postoperative patient are uncomfortable.
Summary of the invention
The purpose of the present invention is to provide a kind of posterior cervical self-lockings to strut fixator, to solve the above problems.
The technical scheme adopted by the invention is that: it provides a kind of posterior cervical self-locking and struts fixator, feature exists
Strutting fixator in the posterior cervical self-locking includes support plate A, support plate B, and described one end support plate A is rectangular
Shape, the other end are isosceles triangle, sliding slot are provided with inside the support plate A, the sliding slot inner wall is provided with ratchet, described
The one end support plate B is rectangle, and the other end is isosceles triangle, and the support plate B rectangle structure end two sides are provided with and institute
The ratchet that the support plate A sliding slot inner wall ratchet stated matches, the support plate B are inserted into inside the support plate A
In sliding slot.
Further, the ratchet is right angled triangle, the tooth tip direction direction support of the ratchet of the support plate A
The rectangle structure end of plate A, the tooth tip direction of the ratchet of the support plate B is towards the rectangle structure end of support plate B.
Further, the support plate A and support plate B isosceles triangle one end are provided with hangnail.
Further, the support plate A and support plate B are provided with pressing tongs slot.
The beneficial effects of the present invention are: the design is for posterior cervical through spatium intermusculare approach, muscle after the neck that adequately protects
Spinous process ligament complex retains the important features such as ligamentaum nuchae, supraspinal ligament, interspinal ligaments, ligamentum flavum, cuts with piezosurgery osteotomy
Neck 3 struts fixator with self-locking to incision bilateral lamina and is fixed, vertebral plate is maintained to be promoted, moulded again to 7 bilateral lamina of neck
A more roomy canalis spinalis is made, it is postoperative more close to cervical vertebrae physiological structure, truly accomplish nape structural remodeling, drops
The complication of low tradition neck posterior approach, it is easy to operate in art, improve the safety of procedure efficiency and operation.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.

Attached drawing 6 is the main view of pressing tongs of the present invention.
In attached drawing, 1. support plate A, 2. support plate B, 3. hangnails, 4. ratchets, 5. pressing tongs slots, 6. pressing tongs, 7. sliding slots.
Specific embodiment
Below with reference to the drawings and the specific embodiments technical solution that the present invention will be described in detail, to become apparent from, intuitively
Understand invention essence of the invention.
In the accompanying drawings, the present invention provides a kind of posterior cervical self-lockings to strut fixator, including support plate A1, support plate
B2, described one end support plate A1 are rectangle, and the other end is isosceles triangle, and sliding slot 7, sliding slot 7 are provided with inside support plate A1
Inner wall is provided with ratchet 4, and correspondingly, the one end support plate B2 is rectangle, and the other end is isosceles triangle, the support plate B2 long
Square structure end two sides are provided with the ratchet matched with the 7 inner wall ratchet 4 of support plate A1 sliding slot, and the ratchet 4 is straight
Angle triangle, the tooth tip direction of the ratchet 4 of the support plate A1 is towards the rectangle structure end of support plate A1, the support
The tooth tip direction of the ratchet 4 of plate B2 is inserted into the support towards the rectangle structure end of support plate B2, support plate B2
Inside plate A in sliding slot, because ratchet 4 is triangular structure of right angle, it can make support plate A1, support plate B2 can only when working in coordination
It is moved along direction disconnected from each other, and then the vertebral plate cut when operation can be made to open certain angle, while had again reversed
Locking function is still able to maintain the angle adjusted when support plate A1, support plate B2 are pressurized, when being performed the operation, will press
6 pincers ends of pincers are inserted into support plate A1, in the pressing tongs slot 5 that support plate B2 is provided with, and operation pressing tongs 6 makes support plate A1, the edge support plate B2
Direction movement disconnected from each other, and then the vertebral plate of bilateral cutting is pushed to open suitable angle, facilitate surgical procedure.
Present invention is mainly used for posterior cervical invasive surgery formulas, when in use, cut neck 3 to 7 bilateral of neck with piezosurgery osteotomy
Vertebral plate pulls backward through body surface, and after the vertebral plate of bilateral cutting opens certain angle, the present invention is protruded into vertebral plate and corresponding
In articular process cancellous bone, pushes bilateral plate fixation to strut osteotomy gap by pressurized clamp, and utilize self-locking function of the invention, rise
Effect is strutted to fixation, one more roomy canalis spinalis of refigure is postoperative more close to cervical vertebrae physiological structure.
