Description
Technical field
This utility model relates to a kind of spinal column way of escape does not have the guider that ray is put nail, belongs to medical instruments field.
Background technology
The development since coming out the eighties in last century of pedicle screw technology has been widely used in the operative treatment of illness such as spinal column degeneration, centrum olisthe, spinal canal stenosis, vertebral fracture, deformity, metastatic tumor of bone, spinal column unstability rapidly.At present, pedicle screw is one of internal fixation device that is most widely used in the spinal surgery, but in practical operation, puts the process of nail and need have an X-rayed repeatedly, and when particularly putting nail in little otch or percutaneous Wicresoft, the number of times of perspective is obviously to increase.The low dose of ray exposure of repeated multiple times at present is still indeterminate to patient and medical personnel's infringement, and still, patient and medical personnel's ray exposure is the common recognition of present all spinal surgeons in the reduction spinal surgery art.
The location of the mid-nail of art is to rely on X-ray machine at present, operation is to have an X-rayed repeatedly and to adjust in the art, quantity of X-rays X needed perspective repeatedly especially when little otch was put the nail operation, the ray that obviously prolongs patient and medical personnel exposes, prolong operating time, and perspective also increases the probability that operative incision infects in the art.Though up-to-date robot system does not need perspective in putting the nail process, need pre-buried location metal needle before its art, simultaneously also need to carry out CT scan, patient's ray does not expose and reduces, and the misery inserted of extra increase positioning needle.In addition, robot costs an arm and a leg, and the whole world also only has hospital few in number to use at present, can't penetration and promotion.
The utility model content
The utility model purpose: the purpose of utility model is to put when operation nail carrying out the vertebra way of escape, provide a kind of can assisting to put the nail guider accurately, fast and easily, use this device to put the nail operation down in that no ray or minute quantity ray are auxiliary, obviously reduce patient and medical personnel's ray exposure.
Technical scheme: a kind of spinal column way of escape described in the utility model does not have the guider that ray is put nail, comprises locating rack between spinous process, slide scale and angular transition bar;

Described angular transition bar comprises square metal bar and the tubular element that is complementary with through hole, one end of described metallic rod inserts with through hole and is connected, make the rotation of metallic rod and the rotation of pointer be consistent and can in through hole, slide, the other end of metallic rod is connected with tubular element, described tubular element can rotate around the other end of metallic rod by connector, the axis of described metallic rod passes the axle center of tubular element, described metallic rod is provided with the scale of distance between prompting axle center of tubular element and the slide scale, the internal diameter of described tubular element and pedicle of vertebral arch are put nail open circuit awl equal diameters, finally instruct the angle of pedicle screw of open circuit awl by this tubular structure.
Lower plate is fixedlyed connected with tabular pedestal by joint pin, makes base be the design of bilateral pes valgus type, is convenient to place in the art, particularly can stretch into subcutaneous easily.
The C type structure that grab handle is opened for the side of connect going up lower plate, mid portion is the holding area, mainly be to make things convenient for to grip in the art, and the design of C type can avoid syndeton between the lower plate interference of angle selector bar to be influenced the slip of slide rule.
Further improve technique scheme, the other end of described metallic rod has through hole along its width, and described tubular element is connected with described through hole by two hinges of its sidewall, is carved with the prompting scale that is used to point out rotational angle on the described hinge.
Further improve technique scheme, the lower surface of described tabular pedestal is provided with the spike projection, conveniently is fixed on the supraspinal ligament; The end face of described train wheel bridge is provided with columnar protrusions, knocks this position gently behind the correct placement positioning frame in the art, and the projection on the base will be fixed on the supraspinal ligament.
Concrete operations in the art: patient's lumbar vertebra MRI sagittal bit slice and lateral lumber spine sheet are measured before the art, measured the distance back between the pedicle of vertebral arch projection outer rim and spinous process center on angle between desirable angle of pedicle screw and the supraspinal ligament vertical line and the positive bit slice of lumbar vertebra:
The first step, the surgical exposure preliminary clear and definite pedicle of vertebral arch that finishes is put after the pin mark, the locating rack of this guider is fixed in puts between a nail sections vertebral body and the last joint vertebra spinous process, that is: gripping grab handle with hands, to use hammer to knock the column at locating rack top gently outstanding, then locating rack by the outstanding held stationary of spike on spinous process.
Second step, grip C type grab handle by the assistant, the stable position frame, the patient correctly places the angular transition bar, that is: keep tubular element and pointer almost parallel, pointer position penetrates metallic rod square hole slot when zero degree, the open circuit awl passes the tubulose structure, then by suitably rotating tubular element adjustment open circuit awl direction (because pointer and tubular element interlock, so pointer can depart from zero degree generally speaking) and adjust distance between tubular element and the slide scale, open circuit awl far-end is placed on to be intended putting on the position of pin mark, mobile slide scale, make the pointed angle coil intermediary zero degree quarter, at this moment, the direction of pointer is consistent with the direction of open circuit awl, and the direction of base and supraspinal ligament is consistent, prompting pointer and base are vertical when pointer points to 0 °, are vertical between open circuit awl and the supraspinal ligament just, are adjusted to the inclined to one side and tail drift angle degree of correct head according to the suitable more mobile slide scale of the angle between desirable angle of pedicle screw that records before the art and the supraspinal ligament vertical line.
The 3rd step, the flare angle of retentive control tubular element is 0 °, scale on the viewing angle selector bar, contrast before the art distance between the pedicle of vertebral arch projection outer rim and spinous process center on the lumbar vertebra normotopia sheet then, can determine further whether the selection of pointer point is appropriate, if obvious shortening is arranged then point out the risk that enters canalis spinalis than measuring before the art.After determining to put pin mark, can bore into open circuit after the suitable control flare angle and bore.
This utility model compared with prior art, its beneficial effect is: (1) is simple to operate, grasps easily, doctor's acceptance is good; (2) put the nail reliable for effect; (3) low price; (4) ray that can obviously reduce patient and medical personnel exposes; (5) put in the nail operation in little otch Wicresoft, even do not expose supraspinal ligament, the spinule sample projection of base still can guarantee can accurately be positioned equally between two spinous process across skin, and all feasible for Wicresoft and cutting operation, the scope of application is extensive.
