Description

A kind of cervical vertebra single open-door surgical guide

Technical field

This utility model relates to medical instrument technical field, particularly relates to a kind of cervical vertebra single open-door surgical guide.

Background technology

The operation of posterior cervical single open-door is the common method of the cervical spondylosis such as current surgical intervention multistage prolapse of cervical intervertebral disc, stenosis, ossified posterior longitudinal ligament.In the operation of posterior cervical single open-door, the selection of enabling side and door-hinge side slotting position is extremely important for the successful implementation of operation.If enabling side slotting position is too close to center line, then may cause that open door effect is undesirable, canalis spinalis expanded scope not enough, affect decompression effect；If slotting position is the most outer, it is likely that injure vertebral artery cause massive hemorrhage because groove depth crosses deep, further it is also possible to cause door-hinge to survey complete fracture occurs, affect this side bony union, the consequence such as cause that the instability of postoperative vertebral plate, vertebral plate are closed the door again.

Utility model content

This utility model aim to provide a kind of individuation, make cervical vertebra single open-door surgical guide simple, easy to use, in posterior cervical single open-door is performed the operation, auxiliary determines concrete slotting position, reduces operation risk and complication.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:

A kind of cervical vertebra single open-door surgical guide, including guide plate body, the back side of described guide plate body is and the curved surface of human body lamina surface phase matching, gap and abrasive drilling operating walk way is had on guide plate body, described gap and abrasive drilling operating walk way all run through guide plate body front and back, and described gap is opening down, and described abrasive drilling operating walk way has two, two abrasive drilling operating walk ways lay respectively at the left and right sides of gap, and the left and right sidewall of described abrasive drilling operating walk way is plane.

Preferably, described guide plate body having two fixing Ding Ding roads, two fixing Ding Ding roads lay respectively at the left and right sides of gap, and described fixing Ding Ding road is positioned at inside abrasive drilling operating walk way.When using this surgical guide, fixing nail can be implanted simply and easily by fixing Ding Ding road, so that this surgical guide can be firmly fixed on vertebral plate, reduce operation technique error.

Further, described abrasive drilling operating walk way is from front to back, from both sides to intermediate, inclined.

Preferably, described abrasive drilling operating walk way is to intermediate, inclined 5 °～10 °.

Further, the front of described guide plate body is plane.

Further, two fixing Ding Ding roads are symmetrical with gap.

Further, described guide plate body thickness is 3mm～5mm.

Compared with prior art, this utility model has the advantages that

This utility model the most just can position with the position of cross-notching, on the one hand accurate positioning, can reach optimal therapeutic effect and reduce the generation of complication, on the other hand reducing operating difficulty, shorten young surgical learning curve.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is further elaborated.

As it is shown in figure 1, cervical vertebra single open-door surgical guide disclosed in this utility model, including guide plate body, the back side of guide plate body is and the curved surface of human body lamina surface phase matching, and guide plate body thickness is 3mm～5mm.Gap 1, abrasive drilling operating walk way 2 and fixing Ding Ding road 3 is had on guide plate body, gap 1 and abrasive drilling operating walk way 2 all run through guide plate body front and back, abrasive drilling operating walk way 2 and fixing Ding Ding road 3 all have two, two abrasive drilling operating walk ways 2 lay respectively at the left and right sides of gap 1, two fixing Ding Ding roads 3 also lay respectively at the left and right sides of gap 1, gap 1 is opening down, and two fixing Ding Ding roads 3 are symmetrical with gap 1, and fixing Ding Ding road 3 is vertical with vertebral plate.Fixing Ding Ding road 3 is positioned at the inner side of abrasive drilling operating walk way 2.The left and right sidewall of abrasive drilling operating walk way 2 is plane.As in figure 2 it is shown, abrasive drilling operating walk way 2 is from front to back, from both sides to intermediate, inclined, generally abrasive drilling operating walk way 2 is to intermediate, inclined 5 °～10 °, if patient exists anatomical variation, then position and the angle of inclination of abrasive drilling operating walk way 2 is determined on a case-by-case basis.As in figure 2 it is shown, the front of guide plate body is plane, or as it is shown on figure 3, the front of guide plate body is the curved surface identical with the back side, i.e. guide plate body is obtained by back side stretching.

During use, fully expose neck 2 vertebral plate lower edge to neck 7 vertebral plate, and after wiping out neck 3 to neck 7 spinous process, will attach to the soft tissue scraped clean of neck 3 to neck 7 vertebral plate rear surface；Guide plate body being placed in vertebral plate rear surface, makes guide plate body rear surface be close to vertebral plate rear surface, make gap 1 ride in the spinous process root of residual, gap 1 holds 2nd/to three/2nd of spinous process root Zhou Jing；The left and right lateral margin of guide plate body exceedes the place of dividing a word with a hyphen at the end of a line of vertebral plate and lateral mass, the left and right lateral margin of guide plate body is positioned at 2nd/to three/2nd of lateral mass, upper limb and the lower edge of guide plate body flush with the joint capsule stop of zygapophysial joints, and it is positioned at the inner side of vertebral plate bound, with fixing nail, guide plate body being fixed on vertebral plate rear surface by two fixing Ding Ding roads 3, the lateral wall of abrasive drilling operating walk way 2 is tangent with pedicle of vertebral arch cortical bone；Then vertebral plate is slotted by use abrasive drilling along the sidewall of abrasive drilling operating walk way 2, takes out fixing nail afterwards, takes off guide plate body, carry out operation technique below.

Certainly; this utility model also can have other numerous embodiments; in the case of without departing substantially from this utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and deformation according to this utility model, but these change accordingly and deformation all should belong to the scope of the claims appended by this utility model.
